Beginners on the road may be at a loss in the face of difficult scenes such as narrow road sticking and turning around in place. Don’t worry, your car will automatically "pass"; When the city is congested, the car will automatically adjust (shock absorber, and at the same time control the opening of the switch or the braking force to cooperate), so that bad experiences such as starting to look up and nodding the brakes will no longer occur; The road ahead is sharp, and the car senses it earlier than you do. Steering, braking and suspension work together to reduce the turning radius, making the turning safer and more comfortable …

If the smart car is compared to a person, then the car also needs a smart "cerebellum", that is, the vehicle central coordinated motion controller (VMC) to dominate the whole body movement. As we all know, the brain is an organ that regulates the body’s functions and controls people’s movements and feelings, while the role of the cerebellum is to regulate muscle movements and maintain the balance of the human body. The cerebellum feeds back the information from the exercise to the brain, thus playing the role of regulating and correcting the exercise. The "cerebellum" of the intelligent chassis is not simply executed after receiving the instructions from the central computing and decision-making unit "Brain", but comprehensively considers the current application scenarios, optimizes the handling performance and ride comfort on the basis of ensuring vehicle safety, and then distributes the instructions to steering, braking and suspension, and finally realizes the coordinated control of six degrees of freedom (front and rear, left and right, up and down) in X, Y and Z directions, "muscle" and ""

In the next three years, SAIC will devote itself to building a brand-new "scientific and technological life". Including "intelligent brain", "agile body" and "strong heart". Among them, the "agile body" is the first to achieve a breakthrough in the "VMC technology of the whole vehicle", which keeps the vehicle body stable in different driving modes and various road conditions. It is reported that VMC will be first applied to the new Zhiji car next year. At present, SAIC’s intelligent solution integrating people, vehicles and environment is undergoing research and development, testing and verification.

Chassis by wire or smart car
The last piece of "puzzle"

In the new electronic architecture, the automobile execution system is also undergoing changes. From traditional chassis to electric chassis, and then to intelligent chassis, automobile chassis is welcoming brand-new changes.

Vehicle control is nothing more than longitudinal control represented by braking, lateral control represented by steering, and suspension control represented by up and down, which corresponds to six degrees of freedom of automobile movement. In order to meet the strict requirements of faster response speed and higher control accuracy of automatic driving, intelligent chassis needs brake, steering and suspension components by wire, and intelligent chassis has also become a wire-controlled chassis.

Chassis-by-wire system transmits the driver’s operation command to the actuator through the electronic controller, replacing the connection and execution from the traditional mechanical structure such as steering wheel and pedal, so it has the advantages of high precision, high safety and high response speed. By controlling the chassis with digital signals, the mechanical decoupling of the control system and the execution system can be realized. The drive-by-wire chassis can not only meet the requirements of higher-level automatic driving, but also enrich the imagination space of the intelligent cockpit and bring a safer and more comfortable driving experience to the occupants.

The chassis by wire mainly includes three core components: brake by wire, steering by wire and suspension system. Among them, brake-by-wire can not only meet the requirements of rapid response of automatic driving, but also meet the rigid requirements of energy recovery and increasing cruising range of new energy vehicles, and the market penetration rate is rapidly increasing. At present, the electro-hydraulic braking EHB system has been widely used in high-end pure electric vehicles. Although additional safety redundant equipment is needed, the intelligent Two-Box scheme is still more common in the short term, and the penetration rate of the intelligent One-Box will be significantly improved in the next few years.

Steer-by-wire steering is a rigid demand in the intelligent driving stage, which is gradually emerging. At present, it is in the stage of research and development verification and just getting on the bus, and it will also become a technical hotspot in the next few years. In the next 10 years, the penetration rate of steer-by-wire will reach 50%.

Since the beginning of this year, the air suspension system has been put on the market with some models, and the market popularity has also climbed once.

From the reality, with the acceleration of intelligent by-wire control system in smart electric vehicles to improve the competitiveness of brand models, by 2025, the domestic smart chassis market is expected to expand rapidly, which is expected to reach more than 50 billion yuan. Among them, the technical reserve of brake-by-wire is relatively mature, and the market is expected to grow at a compound annual growth rate of 34% from 2022 to 2025; In the next 4-5 years, the improvement of its assembly rate will provide a core increment for the smart chassis market, while steer-by-wire and air suspension are expected to enter the pre-assembly lead-in period in 2025.

Cross-domain fusion
Flexible deployment

From a technical point of view, at present, there is a trend of integration of various systems of automobiles, such as intelligent cockpit and intelligent driving, which are being integrated across domains. Zhang Ying, president of Bosch Chassis Control System in China, said that compared with the traditional chassis control system, in which all components are relatively independent for longitudinal, lateral and vertical vehicle dynamic control, VMC can adapt the chassis that was basically "just for itself" to the trend, and integrate the functions of transmission system, driving system, steering system and braking system into multiple systems, which greatly improves the vertical integration ability of chassis development, and can be flexibly deployed in pairs.

Steering and braking integration. It is very difficult for ordinary drivers to slam the steering wheel or make a big correction if they turn a corner on the icy road. When steer-by-wire and brake can be combined, the steering wheel angle and brake controller of steer-by-wire can be controlled in coordination, and the brake and actuator of steer-by-wire are integrated. Ordinary drivers can turn with the help of technological innovation, without worrying about oversteering or understeering, avoiding obstacles successfully and easily turning corners smoothly.

Brake and suspension fusion. Suspension system should not only meet the requirements of comfort, but also take into account the requirements of handling stability. Comfort is also related to the braking system. If the braking is too urgent, there will be phenomena such as braking nodding and unstable control. Comfortable braking function makes you an "old driver" in seconds. Through the precise software control of the system, a part of the braking pressure can be released smoothly in an instant before the vehicle stops, which can greatly alleviate the vehicle nodding and ensure the vehicle to stop very safely.

Integration of braking and power system. When the car starts on smooth roads such as snow and ice, the driving wheels may slip and the direction will be out of control, which will lead to danger. The driving torque vector control and braking control are combined with each other, and the acceleration potential of the vehicle is fully tapped, the curve limit is exerted and the dynamic response is optimized through the optimal distribution of axle or wheel torque.

Integration of VMC and ADAS. In order to meet the richer functional experience in NAD autopilot scene, the chassis needs to provide a bearing platform for autopilot system, cockpit system and power system. In the NAD autopilot scenario, VMC can integrate four-wheel drive distribution, brake-by-wire and variable suspension functions to maximize the dynamic performance of the vehicle, while supporting high-level autopilot scenarios. Through FOTA upgrade, it can be flexibly upgraded and quickly iterated.

Safety and comfort
Have your cake and eat it.

As a safety component, intelligent chassis has the highest functional safety level requirements. Functional safety is the core requirement of intelligent chassis and autonomous driving development. If the high-order automatic driving system comes, redundant braking and fail-safe will become the most important. Only on the basis of safety can driving be pleasant, comfortable, agile and personalized.

When the smart car develops to L3 or above, the driver will no longer control the car for a considerable part of the driving process, and the main responsibility of driving has changed from the driver to the system itself, which brings great challenges to the performance and safety of the whole chassis. For the drive-by-wire chassis, the most important requirements are safety and redundancy, and redundancy is also safe in essence. VMC has two backup schemes of independent actuators. When the main controller fails, the redundant controller takes over, which can systematically reduce the risk of failure of key functions.

The intelligent chassis is divided into two important parts: one is the chassis execution part, which realizes the coordinated control in X, Y and Z directions and the coordinated wire control optimization; Second, the chassis domain control system, based on the advantages of strong hardware and high performance chassis, further realizes the whole domain fusion control and rapid iteration of chassis through experience drive.

With the development trend and evolution of centralized electronic and electrical architecture, chassis control will be promoted to the concept of "domain". Combined with the chassis hardware system, the intelligent chassis domain controller can comprehensively design and adjust the chassis comfort and handling.

VMC can uniformly adjust and control air spring height, shock absorber damping, electronic parking and other functions. The controller detects the vehicle state through the signal received by the sensor, determines the optimal parameter instruction according to the algorithm or control strategy, adjusts the spring stiffness and damping state of the shock absorber, and increases the correction of pitch and roll to enhance the control of the vehicle body. For example, when driving in the field with poor road conditions and encountering a protruding obstacle in front, VMC system will "command" the air spring to raise the height of the car body, and at the same time adjust the electric shock absorber to make the vehicle smooth. In the face of bumpy roads, the system will also use compensation braking to alleviate jitter.

Thanks to VMC, after adjusting a large number of key components such as tires, air suspension and steering system, each car realizes the combination of comfort and handling, and develops various driving modes such as sports, comfort and energy saving according to road conditions and driving habits of users to meet the individual needs of users. At the same time, VMC relies on continuous collection and identification of users’ personalized driving data, and provides driving experience that meets users’ psychological expectations through human-vehicle interaction and self-learning iteration.

Different routes
"Zero" requires cooperation.

The Roadmap of Intelligent Chassis Technology for Electric Vehicles establishes the development goal of intelligent chassis, and the overall goal is that by 2030, intelligent chassis will meet the requirements of first-class products and leading technology. "The next 10 years will be a major strategic opportunity period for China’s intelligent chassis technology innovation and industrial development." Li Jun, then chairman of China Automotive Engineering Society, pointed out at the 2023 Electric Vehicle Intelligent Chassis Conference. At the same time, the intelligent chassis industry has also entered a critical stage of technical competition. Among them, the chassis domain controller has become a battleground for intelligent chassis development.

In the past, the international Tier 1 controlled the core of chassis control technology and provided "black box" chassis solutions for car companies. Many car companies, especially China brands, are highly dependent on suppliers’ development support, and the development time is long and the constraints are high, resulting in the lack of deep-seated chassis function integration development ability of the main engine factory, which makes the vehicles only meet some simple basic driving experiences, with few extended functions and relatively single driving experience.

On the one hand, with the rapid launch of new models, car companies urgently need to change the current situation. In the view of some OEMs, the high integration of software and hardware and cross-domain integration control ability are the core competencies that car companies must have in the era of smart cars, and they must be in their own hands. At present, some OEMs, such as BYD, Ideality and Weilai Automobile, have started full-stack self-research in this respect, and tend to plan chassis domain, convergence domain and other architectures, and lead the development of application software, and also put forward the requirements of "white box" delivery software for suppliers.

On the other hand, the international Tier 1 will obviously not give up the current market interests. Bosch China said that ABS and ESP are one of Bosch’s main products at present, and we are taking smart chassis as our next goal. ZF and Jidu have jointly developed the next generation of intelligent chassis technology to support automobile robots to "move freely".

With the continuous upgrading of R&D technology, coupled with the advantages of stable supply chain, rapid development and market response, China suppliers are likely to catch up with others. Among them, since the mass production of One-box line control products in 2021, Bethel has carried a number of models to the market. At the same time, local start-ups such as Nathan, Tongyu, Likun and Grubo have successfully mass-produced brake-by-wire products based on the Two-box scheme, achieving a new breakthrough in localization.

There are various indications that in the field of intelligent chassis, especially in VMC, the boundary between OEMs and suppliers in the technical field has become blurred, and the technical route of domain controllers will also be "contended by a hundred schools of thought". Borders are often fought out, but at the same time, there are opportunities for cooperation in competition.

Zhang Jinhua, chairman of the China Society of Automotive Engineering, suggested that we should advocate adhering to the sense of cooperation, deepen the whole-scale cooperation, cross-border cooperation and international cooperation, and deepen the synergy between the industrial chain.

Although the full-stack self-developed chassis domain control allows the main engine factory to master more autonomy, it also needs to consider the cost and efficiency. The drive-by-wire chassis products need a lot of adjustment work and the full cooperation of the parts manufacturers. The advantage of the main engine factory is to integrate the parts control provided by suppliers. In the future, the direction of cooperation between the two parties is likely to be to jointly define the system architecture and development design, and all parties will contribute their own "points" and unite to achieve a "breakthrough". Specifically, the supplier may only be responsible for providing the hardware and doing the underlying driver, and then open the control right to the OEM to do in-depth joint development with the OEM, so as to improve the development efficiency and software reusability, speed up the iteration and reduce the cost.

Xiaomi car first exposure! Is it exciting to open books at a low price?

Author | Li Yan Source | Brand Front Page

Some time ago, Lei Jun’s annual speech was screened on the Internet.

Some netizens found that in the three-hour discussion about brand growth and cognitive breakthrough, Lei Jun didn’t say anything about building a car, which suddenly triggered various speculations.

Just a few days ago, it was revealed that Xiaomi had been successfully approved by the planning department and had the qualification to produce electric vehicles.

What followed was the photo that Lei Jun recently posted on the social platform. The banner read "Fight for Xiaomi Car!"

Laman expectation

On August 23, some media reported that Xiaomi had been successfully approved by the planning department and had the qualification to produce electric vehicles.

This indicates that,Xiaomi Auto is one step closer to the goal of mass production early next year.

Xiaomi has also become the fourth company approved to build a car since the end of 2017.

It is reported that if a company wants to enter the field of new energy vehicles, it needs to obtain "double qualifications" to meet production and sales. The acquisition of double qualifications is extremely difficult.

This is one of the reasons why Weilai, Tucki and other new car-making forces choose OEM.

As can be seen from other media reports, Xiaomi has investment layouts in five major areas: intelligent driving, intelligent cockpit, intelligent network connection, intelligent electric power and car cloud service.

As the industrial chain matures, Xiaomi Automobile will be officially on the road soon.

In fact, Lei Jun basked out."Fight for Xiaomi Automobile"At the time of the banner, some netizens posted spy photos of Xiaomi cars galloping on the highway in Xinjiang.

At the same time, Hu Zhengnan, a partner of Shunwei Capital Investment, also exposed the energy consumption performance of Xiaomi Automobile during Lei Jun’s release of a series of Weibo trends located in Xinjiang.

Under normal circumstances, a medium and large car, such as Tucki P7, Tesla Model S and other single-motor models, whose energy consumption per 100 kilometers is less than 15kWh is an excellent level.

The Xiaomi car under test has an energy consumption data of 8.8kWh, which is far lower than the current average of 15.8, and it can be regarded as excellent performance.

As soon as this data came out, it directly filled the expectations of rice noodles.

It is reported that,Xiaomi plans to produce about 100 thousand electric vehicles next year. At the same time, it is confirmed that the battery suppliers at this stage are Zhongchuang Singapore Airlines and Contemporary Amperex Technology Co., Limited.

As the attention continues to rise, the design of Xiaomi car’s configuration, laser radar, frameless door and closed grille exposed by bloggers in May this year is even more eye-catching …

Mass production is imminent

As early as Xiaomi Investor Day in October 2021, Lei Jun said that Xiaomi Automobile is expected to be officially mass-produced in the first half of 2024.

In the past three years, news about Xiaomi automobile has emerged from time to time. News such as the completion of the first phase of the factory and the purchase of spare parts confirmed the steady progress of Xiaomi’s car.

At present, there seems to be more and more "breaking news" about Xiaomi Automobile.

According to media reports, the photos of Xiaomi’s new car road test show that the first model will be a coupe with a slip-back design.

The seemingly long front of the car is slightly different from the inherent impression of netizens on pure electric vehicles. At the same time, the new car is expected to have a closed front end design to further optimize aerodynamic performance.

In addition, although the car body is covered with "camouflage", it can still be seen that lidar equipment is mounted on the top of the car.

Some netizens boldly gave an "irresponsible" guess through the details of the pictures-at least there are two versions with and without lidar.

The first one is that the roof is equipped with a laser radar, and the wheel hub adopts a hollow Y-shaped hollow shape, as well as a "high-equipped" version of the yellow brake caliper.

The other is that there is no lidar on the roof, and the hub shape is more focused on reducing air resistance than the previous hollow design.

Of course, in addition to configuration, netizens are more concerned about the pricing of Xiaomi Automobile.

After all, Xiaomi can quickly occupy the minds of young consumers by maximizing the cost-effectiveness advantage.

In June of this year, Xiaomi’s intelligent AI assistant "Little Love Classmate" made an own goal of "Xiaomi Car Pricing" when answering questions from users.

The head of public relations of Xiaomi Group denied rumors in Weibo: "Xiaomi Auto will be released next year, so how can there be a price now? Xiao Ai’s reply was to grab a report on speculation in 2022. "

However,According to the price of "online transmission", the high-end version may cost 299,000 yuan, and the low-end version is 199,000 yuan..

Xiaomi insiders said that the price will be adjusted according to the market situation next year, and this price may not be the final pricing.

If this price is true, it seems to be a little far from "the first electric car for young people".

What we prefer to believe is that Mr. Lei has "persuaded the board of directors overnight".The overall profit margin of Xiaomi’s hardware will not exceed 1%.. As for the profit point, it depends on software services and ecosystem.

In those days, Lei Jun beat down the price of mobile phones by "overnight persuasion", and consumers used high-priced products with real prices.

Therefore, the profit rate of "persuading executives overnight" will not exceed 1%, which makes netizens have the expectation that "good things are about to happen".

Intellectual priority

In fact, in the new energy track, the profit margin of no more than 1% is basically a beautiful imagination.

For any car company, it needs to rely on huge scale effect to achieve it.

The "small profits but quick turnover" often mentioned in the consumer market, if you want to maintain the daily expenses of car companies, I am afraid it is a bit difficult to even "plug your teeth".

Take BYD, the industry’s "profit extreme", as an example.

Some investment banks have done rough calculations. The cost price of BYD’s 2023 Qin Plus DM-i is 99,000 yuan, while the starting price of this model is 99,800 yuan.

This also means that selling a BYD may only earn a few hundred yuan, and the profit rate is even less than 1%.

From the data point of view, its net interest rate in the first quarter of 2023 was only 3.64%, even lower than the 7.15% of Toyota, a traditional fuel vehicle company.

As a new energy head brand, this is still the case. It just means,At present, the "model" of hardware comprehensive profit rate in the automobile market is less than 1%, which is really a beautiful imagination..

However, BYD has perfect upstream and downstream industries, and many factors are affecting the profit margin of the brand.

For BYD, the premise of "small profits but quick turnover" is the efforts of cost control such as upstream and downstream connection and mass production, as well as the revenue support of multiple explosions at the same time.

For Xiaomi Automobile, the advantage lies in the sound volume of Xiaomi brand and the cognitive label of "cost performance".

The existence of these stickers made Xiaomi, which sold 33.2 million mobile phones in the second quarter of 2023, still attractive in the eyes of consumers.

Nowadays, the automobile market has reached its peak. Whether Xiaomi Automobile can once again come up with a cost-effective "killer" to conquer consumers is another matter.

Some netizens believe that the new energy track may only be low enough to subvert the industry.

In my opinion,Sufficient low price is based on cost control, showing the leading edge of intelligent driving, chips, power batteries and other fields..

Since the new energy track was opened, the price is not the only consideration for consumers to buy, but the better product "intelligence" and user experience are.

In March, 2021, when Lei Jun officially announced that Xiaomi was building a car, he said: "I am willing to put all my reputation in life and personally lead the team to fight for Xiaomi Automobile."

When the mass production of Xiaomi car is just around the corner, will this dream of building a car with Lei Jun’s reputation in life conquer more young people?

We will wait and see.

Expert: Microsoft Black Screen is suspected of illegally controlling the computer system.

  In recent years, China’s Internet users have maintained sustained and rapid growth. By the end of November this year, the number of Internet users had reached 290 million, surpassing the United States and ranking first in the world. At the same time, the network "hacker" crime is also increasingly rampant.


  The crime of hacking into civil computers


  In recent years, China’s Internet users have maintained sustained and rapid growth. By the end of November this year, the number of Internet users had reached 290 million, surpassing the United States and ranking first in the world.



Microsoft’s monopoly is controversial.


  Criminal law amendment


  Yesterday (December 23rd), the National People’s Congress Standing Committee (NPCSC) deliberated the seventh draft of the Criminal Law Amendment. The new draft specially adds relevant clauses to crack down on hacker crimes, and its application scope extends to other computer information systems other than state affairs, national defense construction and cutting-edge science and technology.


  In addition, the revision of the new draft will also crack down on "underground money houses" and illegal operation of securities, futures and insurance businesses, and it is planned to clearly define the constitutive elements of the crime of organizing pyramid schemes.


  Keywords: 1 Hacking crime


  Providing hacking programs will also be punished.


  Internet hackers who illegally control a large number of computers may face jail time. The seventh draft of the Criminal Law Amendment, which was considered by the National People’s Congress Standing Committee (NPCSC) for the second time, defined the serious act of illegally invading the civil computer information system as a "crime", which was added at the suggestion of the Ministry of Public Security.


  Article 285 of the Criminal Law has stipulated that anyone who invades the computer information system in the fields of state affairs, national defense construction and cutting-edge science and technology shall be sentenced to fixed-term imprisonment of not more than three years or criminal detention. The Ministry of Public Security believes that at present, some people use technical means to illegally invade computer information systems beyond the above provisions, which seriously endangers network security, and criminal responsibility should also be investigated for such acts.


  Li Shishi, deputy director of the NPC Law Committee, said in his explanation of the draft that the draft adds two provisions to Article 285 of the Criminal Law: "Whoever violates state regulations, invades other computer information systems other than those specified in the preceding paragraph, obtains data stored, processed or transmitted in the computer information system, or illegally controls the computer information system, if the circumstances are serious, shall be sentenced to fixed-term imprisonment of not more than three years or criminal detention, and shall also or shall only be fined; If the circumstances are particularly serious, he shall be sentenced to fixed-term imprisonment of not less than three years but not more than seven years and fined. "


  At the same time, "those who provide programs and tools specially used for invading or illegally controlling computer information systems, or who knowingly provide programs and tools to others for invading or illegally controlling computer information systems, if the circumstances are serious, shall be punished in accordance with the provisions of the preceding paragraph."


  Keywords: 2 Underground money house


  Run an underground money house or investigate criminal responsibility


  The seventh draft of the Criminal Law Amendment also added provisions to crack down on "underground money houses". "Those who illegally engage in securities, futures and insurance business without the approval of the relevant state authorities, or illegally engage in fund payment and settlement business, with a large amount, shall be investigated for criminal responsibility."


  This regulation comes from the rampant activities of "underground money houses" put forward by the Legislative Affairs Office of the State Council and the Ministry of Public Security. It is suggested that the behavior of "underground money houses" to evade financial supervision and illegally handle large-sum fund transfer and other fund payment and settlement services for others should be listed separately in the criminal law on the crime of illegal business.


  Keywords: 3 military vehicle number plate


  Buying and selling military cards can be sentenced to a maximum of seven years.


  The first-instance draft of the amendment to the Criminal Law stipulates the act of forging, stealing, buying or selling or illegally providing or using special signs such as the number plates of armed forces vehicles, and stipulates that the maximum sentence is three years’ imprisonment. The revised draft raises the maximum term of imprisonment for the above-mentioned acts. If the circumstances are particularly serious, they will be sentenced to fixed-term imprisonment of not less than three years but not more than seven years and fined.


  The draft of the second instance did not make any new amendments to the provisions of the draft of the first instance, such as the sentencing of the crime of huge amount of property with unknown sources and the crimes committed by people around public officials.


  Keywords: 4 MLM crime


  Organize pyramid selling to clarify the form of crime


  On the basis of adding the crime of organizing pyramid selling, the new draft further clarifies the constitutive elements of this crime form. In the second draft, it is clearly stipulated that in the name of business activities such as selling goods and providing services, organizations and leaders require participants to obtain the qualification of joining by paying fees or purchasing goods and services, and form hierarchies in a certain order, directly or indirectly using the number of developers as the basis for remuneration or rebate, inducing and coercing participants to continuously develop pyramid schemes in which others participate, defrauding property and disrupting economic and social order, shall be sentenced to fixed-term imprisonment of not more than five years or criminal detention and fined; If the circumstances are serious, he shall be sentenced to fixed-term imprisonment of not less than five years and fined.


  "Microsoft’s black screen is no different from hacking." Experts say that Microsoft is suspected of "illegally controlling" the computer system.


  ■ Expert interpretation


  Defining "illegal control" is first of all against the will of the parties. Lv Jingjian, director of china computer federation, said that Microsoft’s previous "black screen" action was the same as that of a hacker from a technical point of view-it modified the computer without authorization.



Microsoft giants (Gates on the left and Ballmer on the right)


  [Keywords:] illegal control


  Against the will of the parties


  As for how to define illegal control, Lv Jingjian, director of china computer federation, thinks that it is against the will of the parties, such as remotely modifying the settings-how to use and configure the computer is the right of the user, and implementing the modification without authorizing a third party is against the will of the parties. In addition, large-scale control of other computer information systems should also be suspected of the provisions of the current draft, but if it is just a prank, it is difficult to define it as a crime.


  Lu Jingjian said that from a technical point of view, general computer information systems have loopholes, and if they are discovered by opponents, they will be attacked. The service of providing bug fixes can be regarded as a commitment and responsibility for product quality. And Microsoft’s black screen plan, when repairing for users, left something behind-two plans of Microsoft’s black screen, WGA(WINDOWS Value-added Plan) and OGA(OFFICE Value-added Plan), were released to provide value-added services for genuine users. If Microsoft finds that users are not using genuine products during the service, it will leave a "logic bomb" and black the screen once an hour. Accordingly, he believes that Microsoft is the same as a hacker from a technical point of view.


  [Keywords:] information system


  Widely used in life


  For non-professionals, the understanding of computer information system is usually desktop computer. Lu Jingjian explained that without an operating system, it is also a computer system to directly run operating codes.


  At present, the embedded system accounts for more than 90% of the application of computer information system, but it is also a big loophole in network security. For example, some imported printers have embedded processors. When printing through a computer, the data is first stored in the memory, but it will not be deleted after printing, so it may be stolen.


  Embedded systems are widely used in elevators, cars and mobile phones, and remote control is entirely possible.


  [Keywords:] hacker role


  Face up to potential and strengthen guidance


  As a director of the Computer Society, Lv Jingjian does not agree to crack down on hackers. "Hackers, Ke Bai and honker have made special contributions to the work of improving technology. For example, 70% of the defects in computer software are detected, and many defects are picked out by these people."


  Lv Jingjian believes that they can play their role in many aspects. For example, after the important software comes out, some people can be called to help test it, and some rewards will be given after the test. Lv Jingjian believes that if there are these channels, most people may go in this direction, and the remaining "Jiang Yang thieves" will be few, and the public security departments can also concentrate on dealing with them.


  He suggested that after the introduction of the law, the state should introduce supplementary measures and reward mechanisms. "Industry and academia should face up to hackers and guide them to the right path." (The text is a pseudonym) (Wu Peng)

"Fitness Path", have you used it correctly?

  There is a beautiful scenery in the community, by the river and in the park. Have you noticed it? It is a fitness area composed of some brightly colored fitness equipment, where grandparents or parents often play with their children. Do you know what these instruments are called?

  These fitness equipment have a name, and its scientific name is "National Fitness Path".

  Generally speaking, the "national fitness path" is mostly located in parks, green spaces, rivers and residential areas with good environment. A kind of sports equipment is installed at intervals, and there are paths connecting all kinds of equipment, which is the road to health. Because it is more suitable for ordinary people to exercise, it is called "National Fitness Path".

  What is the "fitness path"?

  In order to implement the national fitness plan and promote the development of urban and rural residents’ fitness activities, the government has invested in building national fitness centers and multi-functional sports venues to provide venues and equipment for residents’ fitness activities, and the "National Fitness Path" is one of the important components.

  The "national fitness path" refers to outdoor fitness equipment suitable for the masses to exercise. One kind is installed at intervals, and there are paths between the equipment, so it is called "fitness path". At present, under the guidance of national policies and guidelines, most urban and rural areas in China have built a series of community fitness paths, administrative village fitness paths and park fitness paths. These fitness paths play a positive role in strengthening people’s physique and can meet the fitness needs of different people.

  What is the use of "fitness path"?

  As the name implies, the "fitness path" is used for fitness, which is composed of a number of fitness equipment with different functions. These devices can exercise arm strength, leg strength, waist and abdomen strength, relax muscles and exercise our speed and flexibility.

  The "national fitness path" can also improve the physical function and quality of ordinary people, relieve the work pressure and mental depression, and finally achieve the goal of preventing and curing diseases and prolonging life.

  What changes have taken place in the body of middle-aged and elderly people?

  In the middle-aged and elderly population, a series of changes have taken place in body shape and function, such as decreased body organ function, decreased cardiopulmonary function, decreased muscle, decreased strength, decreased nerve function and flexibility, and increased body fat. Fitness exercise plays a great role in keeping the middle-aged and elderly healthy, prolonging life and improving the quality of life. The fitness path around us provides a good fitness venue and equipment for middle-aged and elderly friends. However, the adaptability of middle-aged and elderly people is obviously reduced, and their ability to respond to sports stimuli is poor. Faced with numerous equipment on the fitness path, it is easy to cause sports injuries if it is not properly selected. Therefore, the use of fitness path is more important for middle-aged and elderly people.

  What problems should middle-aged and elderly people pay attention to when using fitness path?

  First of all, regular physical examination to understand the health level and physical condition.

  Secondly, safety comes first. It is suggested that middle-aged and elderly people should walk together when exercising through the fitness path, and try not to be alone. If there is any discomfort in the exercise, stop it immediately. Pay attention to the weather changes when exercising, and it is not advisable to exercise in bad weather such as cold, wind, rain and fog.

  Third, pay attention to dress when exercising, wear soft, warm, light, breathable and sweat-absorbent clothes, and sports shoes with thick soles, good elasticity and appropriate size. In winter, you can wear hats and gloves without affecting safety and exercise.

  Fourth, middle-aged and elderly bodybuilders with diseases or injuries should exercise under the guidance of doctors or professional rehabilitation instructors.

  Fifth, before exercise, we should make full preparations. After exercise, we should pay attention to relaxing and sorting out activities, and replenish water properly during exercise.

Why did nine cars get on the bridge? Three Questions on the Crash Accident of online celebrity Pontoon Bridge in a Scenic Spot in Hubei Province

  □ Our reporter Liu Huan Liu Zhiyue

  □ Intern Yi Jiaxin of our newspaper

  On May 16th, in Shiziguan Scenic Area, Zhushan Town, Xuanen County, Enshi Tujia and Miao Autonomous Prefecture, Hubei Province, a black vehicle broke through the guardrail and fell into the water when passing the floating bridge in online celebrity, which aroused widespread concern in the society.

  On the night of the incident, the Information Office of Xuanen County Government issued a notice saying that a commercial vehicle in Shiziguan Scenic Area, Zhushan Town, Xuanen County fell into the water from the floating pontoon, with eight people on board, three people escaped from danger, and five people died after being rescued ashore. At present, the business of the scenic spot has been suspended, and the aftermath and accident investigation are being carried out in an orderly manner.

  On the morning of May 17th, the reporter of "Rule of Law Daily" called the Lion Pass Scenic Area, and the staff of the scenic area said that they were fully cooperating with the police investigation and actively doing the aftermath, and the subsequent opening hours would be announced separately.

  The cause of the pontoon car crash is still under investigation, but the reporter found that there are at least three questions to be solved about the safety management of scenic spots.

  Limited to seven. Why did nine cars get on the bridge?

  The floating bridge involved in the project is called "Dream of Covered Bridges", which is a key tourism project recommended by Lion Pass Scenic Area.

  According to official website, a scenic spot, the floating bridge is 400 meters long and 4.5 meters wide, which can accommodate 10,000 people to walk on it at the same time.

  During the May Day holiday this year, Mr. Shen, a citizen of Wuhan, Hubei Province, came here to visit the Lion Pass Scenic Area. "There is no separate charge for the pontoon bridge. As long as you buy tickets, you can drive and play, and the traffic volume has not been small." At the peak of play, the pontoon bridge is full of vehicles, one next to the other, resulting in flooding of the bridge deck and difficulty in driving.

  Before driving across the bridge, Mr. Shen also noticed that there was a warning sign at the entrance of the pontoon bridge, which read "No retrograde" and "20 yards speed limit", and there was an automatic speaker at the entrance to remind him.

  It is worth noting that the vehicle that crashed into the bridge was a nine-seat commercial vehicle.

  Ms. Li is a native of Enshi and has visited the scenic spot. According to her memory, before she drove on the pontoon bridge, the staff repeatedly stressed that it was necessary to open the window and pass slowly while driving. Moreover, there are many speed bumps on the pontoon bridge, with relatively short guardrails on both sides and a "speed limit of 20 yards" sign on the roadside.

  However, she found on the pontoon bridge that some tourists were driving fast on the bridge, which made her feel a little jumpy. "How dare you drive so fast?"

  Ms. Li noticed that although there were security guards at the entrance of the pontoon, there was no manned rescue point in the middle of the pontoon at that time, and the exit of the pontoon was unattended.

  The video of the car crashed through the net showed that the black commercial vehicle brought layers of waves when passing through the pontoon bridge, and the tire skidded while driving, and then broke through the guardrail and fell into the water.

  Is it really safe to claim to be able to cross the pontoon bridge of tanks?

  The floating bridge involved is also famous for being "the most beautiful floating bridge in Hubei".

  According to public information, a video platform account named "Shanghai Qihua Water Project" published a short video of "China’s most beautiful online celebrity pontoon bridge dedicated to cars in Shiziguan Grand Canyon, Enshi, Hubei (60 meters deep)".

  According to the video content, the car can float on the bridge: "When the car crosses this pontoon bridge created by the locals, it drives on a green emerald river. The water ripples clear the way, and the left and right handrails move up and down in waves, which has a magical feeling of crossing time and space. "

  The reporter found that on the afternoon of May 17, the above video had been deleted. According to public information, Shanghai Qihua Aquatic Engineering Construction Co., Ltd. is the builder of the pontoon bridge.

  The reporter called the company to interview the safety of the pontoon bridge, but was rejected by the other party.

  According to public information, in March this year, the person in charge of the Lion Pass Scenic Area said in an interview with the media: "The pontoon bridge itself is German technology and used for tanks. There has never been an accident since it was put into use in 2016. "

  However, the safety dispute about the pontoon bridge has always existed.

  According to official website, Enshi Prefecture Government, in August 2019, there were frequent local rainstorms. In order to ensure safety, Xuanen County and Zhushan Town Government, together with relevant departments, formed an inspection team to conduct a four-day safety inspection of Shiziguan Scenic Spot and Chedongping Scenic Spot within their jurisdiction. After the inspection team conducted a safety hazard investigation of the Lion Pass Scenic Area, it issued an instruction to order rectification within a time limit. Among them, the safety facilities for rafting in the scenic spot are not in place, the pontoon bridge has not been identified by safety, and the rafting project is ordered to stop operation immediately, and the pontoon bridge is immediately prohibited from passing.

  Since the beginning of this year, the pontoon bridge has also adjusted its opening plan several times due to the weather.

  On March 7th this year, WeChat WeChat official account in Lion Pass Scenic Area published an article saying that due to the weather, the water level in the scenic area dropped, and all self-driving vehicles could not cross the pontoon bridge. On April 23, the scenic spot once again published an article saying that due to the weather, the water level in the scenic spot rose, and the self-driving route of individual passengers was adjusted to "only run the pontoon ring road".

  Is the hidden danger rectification in place after listing supervision?

  Due to major hidden dangers, the Lion Pass Scenic Area was once listed and supervised.

  Official website, Emergency Management Bureau of Enshi Prefecture, shows that since 2019, the State Work Safety Committee has listed and supervised a number of major hidden dangers found in the state-wide work safety supervision and inspection, and Lion Pass Scenic Area is one of them.

  There are five main safety hazards and problems in this scenic spot: there are no emergency life-saving equipment such as lifebuoys along the pontoon; Sightseeing bus inspection of 4 batteries has expired; Iron railings are used for the highway adjacent to the water in the scenic area, and they are damaged; There are many pumice stones on the mountain wall beside the highway in the scenic area; The 380V power distribution cabinet did not form a fire separation with the ticket office.

  In July, 2020, Lion Pass Scenic Area was awarded the national 4A-level tourist attraction. WeChat official account, the WeChat of the scenic spot, once wrote that the Lion Pass Scenic Spot passed the landscape quality evaluation in June 2018, and after two years of rectification and creation, the environmental quality and service quality of the scenic spot have been greatly improved.

  In April, 2021, the Office of the Enshi State Safety Committee issued a notice saying that the Enshi State Safety Committee Office conducted a spot check and acceptance of some hidden dangers, and decided to cancel a number of major hidden dangers listed and supervised according to the acceptance, among which the Lion Scenic Area was on the list of sales numbers. On April 22 of the same year, the Lion Pass Scenic Area was closed to upgrade the scenic spot and reopened a week later.

  On April 28th this year, Vice Governor of Enshi Prefecture led a team to inspect the safety of special equipment in Shiziguan Scenic Area, urging and guiding enterprises to improve their management and maintenance, requiring enterprises to enhance their awareness of safety responsibility of special equipment, and actively carry out self-inspection and investigation of hidden dangers to prevent safety accidents.

  The safety inspection has not gone far, and the tragedy has already happened.

[Those things in China] Foreign "online celebrity" is optimistic about China’s business opportunities. US media: Keep up with the trend and tap high-quality content to be competitive

  China Daily Online, January 11th In recent years, China’s "online celebrity" economy has grown exponentially. According to the data released by consulting organizations, the number of "online celebrity" with more than 100,000 fans in 2017 increased by 57.3% compared with 2016. For China, a market with 1 billion mobile phone users, foreign "online celebrity" have also found huge business opportunities. Nowadays, more and more foreign faces appear on various social platforms in China.

  According to the American news website The China First News, in 2018,’s "online celebrity" economy was about $14 billion (about 96 billion yuan). The huge fan base and lucrative advertising fees have made a fortune for domestic "online celebrity", and now foreigners are competing to join in the fun. In order to stand out from the fierce competition, foreigners follow the trend and meet the needs of China fans to the greatest extent by providing distinctive content.

  Launch its own brand

  According to the article, foreigners who were famous in China in the past were either international celebrities themselves or lived in Asia. The latter can attract people’s attention for two reasons. First, it is as unconventional as a "bearded spice girl" who has been a wrestler; The second is to become a China hand like a mountain.

  Nowadays, a new type of foreign celebrities has begun to rise. They have often become popular on social media abroad. Although he can only speak a few simple Chinese, the English level of young people in China has improved, and fans often translate subtitles spontaneously, which attracts the attention of many fans in China. In short, these content creators always have something that interests China audiences.

Gavin’s screenshot of Weibo

  Gavin Thomas, an 8-year-old "smirk boy", is an example. In many Asian countries, in order not to offend people or ease the embarrassing atmosphere, people always squeeze out a fake smile. Gavin’s "embarrassed and polite smiles" aroused people’s resonance and made him gain a lot of fans.

  In July 2018, Gavin opened a Weibo account, and the number of Weibo fans has reached 1.95 million, exceeding his fans on Facebook, Twitter and YouTube. Gavin has cooperated with Taobao and launched a series of co-branded products, such as sweaters with his head, which is a change in the way foreign online celebrity realized in China.

  In 2018, there seems to be a new trend among foreign bloggers. They should not only produce high-quality content, but also integrate themselves into all aspects of life in China and form their own distinctive cultural brands. In 2019, foreign "online celebrity" may pay more attention to the interaction with netizens in China, create an influential independent brand in China and realize its realization.

  Multi-platform operation

  The article points out that WeChat and Weibo are the largest social media platforms in China. In addition, social media platforms such as Youku Tudou, Tik Tok, Xiaohongshu, Meipai, and Bili also have many users.

  Previously, foreign "online celebrity" bloggers were mainly active in WeChat and Weibo, but in 2018, a short video boom started in China, with domestic bloggers shooting short videos on various platforms, and foreign bloggers also followed the trend.

  Some of them hang out on short video platforms such as Li Li, some settle in Xiaohong’s writing product evaluation, and some specialize in making funny videos. Some foreign bloggers even have fans in Zhihu. Marie from England can speak fluent Chinese. On social media in China, her name is Tan Manru. Going to Zhihu and making videos made her famous in China.

  In 2015, Tan Manru and China’s popular Chen Han Siri filmed a video, which was posted on Mile Mile, Youku and YouTube, and the number of hits exceeded 37,000. The video released by Chen Han Siri focuses on letting China audience know about western culture.

  When answering questions from Zhihu, Tan Manru often gives her own unique views on cultural differences and explains her understanding of China culture in a humorous way. She won more than 130,000 endorsements and 41,580 collections on Zhihu. After becoming popular on Zhihu, Tan Manru also began to enter other platforms. She settled in the knowledge question-and-answer platform "Be a little better" to provide paid question-and-answer service for fans.

  In 2018, social media in China flourished, and various platforms emerged one after another. Especially with the rise of short videos, creating richer content to help major platforms attract users has become a must for foreign "online celebrity".

  Seek institutionalized operation

  The article thinks that 2018 is the era of short video, with second shot, Aauto Quicker and Tik Tok leading the way. The video ecosystem has also changed in other ways.

  However, as foreign "online celebrity" clustered in China content market, more and more people encountered difficulties in cross-cultural communication and entering the China market. At this time, MCN(Multi-Channel Network) operation mode shows certain advantages. Slivki Show, a Ukrainian video blogger on YouTube, is an example of the cooperation between content creators and MCN organizations. Slivki Show will share interesting scientific experiments and life tips, such as how to squeeze 2 liters of orange juice from an orange. It has more than 1 million fans and 191 million video hits on Youtube. In 2017, Slivki Show settled in Weibo and added Chinese subtitles to the video.

  MCN institutions explore and sign talents, and then push them to various media platforms. Yoola, a MCN company working with Slivki Show, manages more than 72,000 channels on YouTube. Yoola localizes the channels that it thinks are suitable for China audiences.

  People may not have noticed that many foreign entertainers have settled in China social media websites or cooperated with MCN organizations. American model Carly Klaus settled in Little Red Book in May. Actor Robert Downey Jr., singers Taylor Swift and Britney Jean Spears, basketball player Dwyane Wade all opened Weibo, and Radiohead of British rock band also used Weibo. Many of these people’s social media accounts in China are managed by the Fanstang of MCN. And creative rookies can cooperate with many small MCN organizations to localize their content in China market.

  The article points out that in the future, there will be more foreign "online celebrity" active on social media platforms in China, especially those YouTube foreign bloggers who have many fans. They won’t miss the market of China, and they will be more active in 2019.

Live broadcast with goods can not be consumed "trust"

  A number of online celebrity’s recent "tragic auction" incident caused widespread concern. They deliberately design scripts and words, and deceive well-meaning consumers through live broadcast and false marketing. Due to the huge amount involved, the social impact is extremely bad.

  Fake help to farmers, really bring goods. Selling miserable false marketing is indifferent to feelings, unreasonable to reason, and unacceptable to law. What needs to be reflected is that similar farce has been staged repeatedly, and there have been many criticisms on the Internet for a long time. Why can online celebrity, who is under the banner of helping farmers, repeatedly bluff and cheat?

  The cost of traffic fraud violation is low. A script, several actors, through fictional experiences on the Internet platform, can gain the sympathy of netizens, bring goods live openly, and even sell fake and shoddy products. This practice not only infringes on consumers’ right to know, but may also be suspected of constituting a crime. Low risk and huge returns have become the driving force for some live broadcast operators and online celebrity to take risks.

  Live broadcast with goods lacks rigid constraints. In recent years, online celebrity’s economy has developed rapidly. Under the commercial packaging, many anchors have become popular and quickly realized their traffic. Due to the profit-seeking nature of capital, shanzhai is in power and counterfeit goods are rampant frequently. This shows from the side that the live broadcast industry is developing rapidly, but the industry standards and norms that match it should also keep up in time.

  It is difficult to prove consumer rights protection. There are a large number of online celebrity scattered on major live broadcast platforms, and most businesses do not have physical stores. The duration of false propaganda is generally short, so it is not difficult to obtain evidence directly. It is difficult for ordinary consumers to trace the true source of goods, and it is even more difficult to prove online celebrity’s false propaganda. Under normal circumstances, only after the business is subject to administrative punishment can consumers complain with the punishment record.

  The chaos has been repeatedly banned, and the platform is hard to blame. In the pursuit of value that traffic is king, some platforms have become distribution centers for fake goods, which are full of labeled sales and fake and shoddy goods. In the long run, these platforms will overdraw the trust of consumers, leading to the gradual loss of users, and ultimately the loss will outweigh the gain. Therefore, in order to develop healthily in the long run, the platform should strictly filter user content and truly implement disciplinary measures.

  The auction and false marketing not only overdraw the goodwill of the public, but also corrupt the social atmosphere. Online celebrity should realize that the fan economy is a trust economy, and if trust is consumed wantonly, the consequences will be very serious once it is overturned. Since false marketing will cause harm to all parties, it is necessary to strictly investigate the live broadcast accounts that violate public order and good customs to defraud netizens, cut off traffic empowerment and illegal profit-making channels, and also clear the space for online consumption.

Five major urban agglomerations explore the road "hydrogen energy" fuel cell vehicles welcome good results

  In the workshop of Beijing Yihuatong Technology Co., Ltd., workers are assembling hydrogen engines. Information photo

  With the implementation of the "double carbon" strategy, the development of China’s hydrogen energy industry has entered the "fast lane", and the transportation field represented by fuel cell vehicles has become an important breakthrough. The reporter of Economic Information Daily recently learned that the construction of five demonstration urban agglomerations of fuel cell vehicles in China has been accelerated, the core technologies have been continuously broken, and the hydrogen energy industry chain has been gradually improved. Under a series of favorable conditions, the delivery and commissioning of domestic fuel cell vehicles ushered in an intensive period. However, it is worth noting that the hydrogen energy industry is still in its infancy, and it is necessary to make efforts in infrastructure construction and other aspects.

  Fuel cell vehicles are intensively put into operation

  Every day, a number of special "green brand cars" will be ushered in at Shanghai Petroleum Qingwei Oil-Hydrogen Co-construction Station, which is the first batch of fuel cell network cars in China that have been put into operation recently. At present, there are only 80 vehicles in this batch, which operate around Hongqiao Airport and are expected to increase to 200 by the end of the year.

  This is a microcosm of the accelerated application of hydrogen energy in China. In August, 2021, the five ministries and commissions jointly issued the Notice on Launching the Demonstration and Application of Fuel Cell Vehicles, and agreed to start the demonstration and application of fuel cell vehicles in urban agglomerations submitted by Beijing, Shanghai and Guangdong. In December 2021, demonstration urban agglomerations of fuel cell vehicles in Henan and Hebei were successively approved, and a "3+2" fuel cell vehicle demonstration pattern was formed nationwide.

  As the leading city of Beijing-Tianjin-Hebei fuel cell vehicle demonstration city group, the starting area of Daxing International Hydrogen Energy Demonstration Zone built by Beijing was completed and put into operation in March this year. At present, the first phase of the Southern District project has also started construction, and it is expected to be completed within this year, expanding the testing, workshop and office space of the park. The second and third phases of the demonstration area are being planned and designed simultaneously to provide space guarantee for the subsequent projects.

  "We have built a perfect ecological chain for the hydrogen energy industry from special policies, industrial alliances, third-party testing and certification platforms, and standard formulation." Ren Juanjuan, deputy director of Beijing Daxing District Bureau of Economy and Information Technology, said that at present, there are more than 1,000 fuel cell vehicles promoted in Beijing-Tianjin-Hebei urban agglomeration as a whole, and nearly 600 vehicles have been promoted in Daxing District, covering various application scenarios such as tourist buses, sweepers and heavy trucks.

  According to the Fuel Cell Vehicle Database released by GGII, from August 2021 to August 2022, that is, the first year of the national fuel cell vehicle demonstration city group, the cumulative sales of fuel cell vehicles in the five demonstration groups were 2590.

  According to the report of Chuancai Securities, under the background of the steady advancement of local policies, the delivery and commissioning of domestic fuel cell vehicles ushered in an intensive period. In the third quarter of 2022, a total of 1,346 fuel cell vehicles were delivered, of which more than 1,000 were put into use in five demonstration urban agglomerations. As a mature field of hydrogen energy application at present, the industrial effect of vehicle is gradually emerging.

  According to the data of China Association of Automobile Manufacturers, the production and sales of fuel cell vehicles also continued to grow at a high speed. In September 2022, the production and sales of fuel cell vehicles were 183 and 202 respectively, up by 18.1% and 16.8% respectively. From January to September, the production and sales of fuel cell vehicles all reached 2,000 units, up 1.7 times and 1.3 times respectively.

  nucleusHeart technology accelerates breakthrough

  In addition to policy support, accelerating the breakthrough of core technologies is one of the important supports for accelerating the demonstration operation of hydrogen fuel cell vehicles.

  On the north side of Beijing Daxing International Hydrogen Energy Demonstration Zone, in the production workshop of Beijing Yihuatong Technology Co., Ltd., on the production line with an annual output of 3,000 hydrogen energy engines, several workers are assembling precision parts, and monitoring the torque and angle in real time through intelligent electric tightening guns in their hands to avoid rework. On the next channel, countless small QR codes are marked on the ground, and robots shuttle back and forth. They can accurately deliver parts to the door through navigation and positioning technologies such as laser and vision.

  "At present, we have formed a comprehensive integrated hydrogen energy industry solution with fuel cell system as the core, and the power of hydrogen energy engine products independently developed and produced covers 30 kW to 240 kW." Bao Jianpeng, deputy director of the production department of Beijing Yihuatong Technology Co., Ltd. said.

  Another domestic hydrogen engine R&D and manufacturing enterprise in the park — — Beijing Wenli Technology Co., Ltd. has also built a series of fuel cell products and their core components through independent research and development, which are not only used in commercial vehicles and construction machinery vehicles, but also extended to non-vehicle fields such as mobile power supply and distributed power stations.

  "Our fuel cell engine technology is relatively mature, and the planned production capacity is 2,000 sets per year, while the air compressor can currently reach the production capacity of 20,000 sets." Zuo Linlin, deputy general manager of Beijing Wenli Technology Co., Ltd., said in an interview with the Economic Information Daily.

  It is understood that there are currently 139 enterprises registered in Daxing International Hydrogen Energy Demonstration Zone, initially forming a perfect hydrogen energy industry system. "The eight core component technologies of hydrogen fuel cells have basically achieved domestic autonomy and are still being iteratively upgraded." Ren Juanjuan revealed.

  Business people including Zuo Linlin have also felt this change in practice. In the early years, most of the key components and materials of hydrogen fuel cell vehicles were imported from abroad. Now, except for some products such as power semiconductors, the parts purchased by the company have basically been localized, the supply speed has been further accelerated, and the cost of key raw materials has continued to decline.

  Advanced layout of infrastructure

  As a key part of the hydrogen energy industry chain, the role of infrastructure construction can not be ignored.

  Daxing International Hydrogen Energy Demonstration Zone has the largest daily hydrogenation station in the world, with 8 hydrogenation machines and 16 hydrogenation guns, with a daily hydrogenation capacity of 4.8 tons, and about hundreds of hydrogen energy vehicles come here for hydrogenation every day. Hydrogen from the hydrogen refueling station can also be directly transported to the hydrogen-related testing center with an area of 1,500 square meters through pipelines.

  According to the data of the National Energy Administration, by the end of June, more than 270 hydrogen refueling stations had been built in China, accounting for about 40% of the global total, ranking first in the world.

  However, compared with the promotion of hydrogen fuel cell vehicles, the guarantee of hydrogen energy replenishment is still insufficient. "At present, our main limitation is infrastructure. If the hydrogen refueling station can keep up, the fuel cell will usher in an explosive growth." Zuo Linlin said.

  The reporter noted that at present, many places have issued plans to support the development of hydrogen energy industry, and infrastructure construction is one of the key points. For example, at a recent press conference, Tang Wenkan, deputy director of the Shanghai Economic Information Commission, revealed that a special plan for hydrogen refueling stations will be introduced, and the layout will be moderately advanced. In 2025, more than 70 hydrogen refueling stations of various types will be built and put into use to achieve full coverage of key application areas.

  During the "14th Five-Year Plan" period in Guangdong Province, 300 hydrogen refueling stations were built, including over 200 demonstration urban agglomerations. The financial subsidies for the construction of hydrogen refueling stations at all levels can reach up to 5 million yuan. Beijing will give 5 million yuan and 2 million yuan of fixed construction subsidies to hydrogen refueling stations built (including reconstruction and expansion) within the administrative area according to the rated working capacity of compressors of not less than 1000 kg and 500 kg in 12 hours respectively.

  Insiders pointed out that the hydrogen energy industry is still in its infancy, and the problems restricting development such as technology, cost and infrastructure are gradually improving, but it is expected that a major breakthrough will be achieved after 2025. The report released by Kang Yong, chief economist of KPMG China, shows that hydrogen energy is expected to take the lead in commercialization in the transportation field; Green hydrogen production, localization of key materials of hydrogen fuel cells and equipment of hydrogen refueling stations will become hot tracks in the hydrogen energy industry; The regional industrial layout of hydrogen energy has been rapidly formed.
