　　On November 28th, Beijing held the 427th press conference on the prevention and control of COVID-19 epidemic to inform the latest situation.Today 0— At 15: 00, there were 2086 new cases of COVID-19 infection in Beijing.

　　Liu Xiaofeng, deputy director of Beijing Center for Disease Control and Prevention, introduced:From 0: 00 to 15: 00 on November 28, new local COVID-19 virus infections were added.2086 casesAmong them, there were 1907 isolated observers and 179 social screening personnel.

　　Liu Xiaofeng said,The number of newly reported cases in Beijing is still at a high level, and the epidemic situation in Chaoyang District continues to be high. The epidemic situation in the fast-growing areas has expanded, and the epidemic situation in some sporadic areas has increased significantly.

　　Beijing: Strengthening the detection of nucleic acid detection points to prevent cross infection.

　　Xu Hejian, spokesman of Beijing Municipal Government, said:Further optimize nucleic acid detection to achieve safe, orderly and high quality.It is necessary to adhere to the principle of rational, orderly and convenient nucleic acid detection, scientifically coordinate the layout, personnel organization and time arrangement of nucleic acid detection points, and further strengthen the detection of nucleic acid detection points to prevent cross-infection. It is necessary to continuously optimize the process of "collection, delivery, inspection, reporting and verification" to improve the speed, quality and effect of detection, screening and yang chasing. It is necessary to concentrate on improving the quality and efficiency of nucleic acid detection in key epidemic-related townships, quickly find the source of risk, and effectively cut off the chain of epidemic transmission.

　　Some supermarkets and pre-warehouses were temporarily shut down, and nearly 30% of riders were blocked.

　　Guo Wenjie, deputy director of the Beijing Municipal Bureau of Commerce, said:At present, the epidemic situation in Beijing is grim, and the epidemic prevention and control is in a critical period. As the number of people living at home continues to increase, the online demand for residents’ living materials continues to grow. From the daily order, it is about 10% ~ 20% higher than the daily order of 3 million before the epidemic. At the same time, affected by the epidemic, some supermarkets and pre-warehouses were temporarily shut down, nearly 30% of riders were blocked, and the delivery of orders was restricted to some extent. The average daily delivery volume of on-the-job riders increased by nearly 80% compared with daily life.

　　Overall,At present, the online platform goods in the city are sufficient and the price is stable, but in some areas and some time periods, there have been problems of tight transportation capacity and delayed delivery. In the face of the sudden epidemic, the supplier companies race against time to organize the supply of goods, and the takeaway brother spares no effort to take orders for distribution, which basically guarantees the living needs of the general public.The supply network involved in the epidemic requires quick sealing and quick solution. In principle, it should be disposed of and reopened within 24 hours.Guo Wenjie, deputy director of the Beijing Municipal Bureau of Commerce, said:In order to ensure the needs of people’s livelihood, the outlets of the supply sites should be fully opened, and the stocking volume should be increased by 3 ~ 5 times daily.For the supply-guarantee outlets involved in the epidemic, it is required to seal and solve them quickly.In principle, it should be disposed of and reopened within 24 hours, and the closing time should not exceed 72 hours at most.At the same time, establish a green pass mechanism to guarantee the supply of vehicles to ensure that all outlets replenish goods 24 hours a day.Do not empty the rack and keep the goods..Multi-channel recovery of delivery capacity

　　Guo Wenjie, deputy director of the Beijing Municipal Bureau of Commerce, said:Since the outbreak of the epidemic in April 2022, in order to coordinate the epidemic prevention of take-away riders and the distribution of living materials, we have established a "white list" mechanism for suppliers, and strengthened epidemic prevention measures through "four falls and five guarantees", that is, losing identity, store warehouse, distribution area and residential address; Make sure that the nucleic acids are not 0 and 1, and that the results without antigen are not on duty. Make sure to wear N95 mask all the time, make sure that the hands are disinfected before delivery, and make sure that there is no contact distribution in the risk area. It has played an important role in ensuring the supply of daily necessities in Beijing by forming a supply team with strengthened protection and flexible deployment to minimize the number of staff involved in the epidemic or become a source of infection.

　　Since the current epidemic, in the face of severe epidemic prevention situation and supply pressure, the number of "white list" personnel has rapidly expanded from 5,000 to 40,000 in two weeks. In addition, take-away enterprises are encouraged to increase the recruitment of riders by increasing the commission ratio and setting up incentives such as running orders, and to supplement the transportation capacity as soon as possible by coordinating the allocation of manpower in different regions and sharing labor with catering enterprises.

　　Establish emergency safeguard mechanism of vegetable through train

　　Guo Wenjie, deputy director of the Beijing Municipal Bureau of Commerce, said:At present, there are 356 municipal vegetable through trains in 15 through train enterprises, which can provide direct supply services for vegetables and other necessities for about 500 communities and meet the needs of 3 million residents. In addition, 50 postal vehicles have been prepared to form a reserve mobile force, which can be put into distribution at any time. Dynamically monitor the supply of daily necessities in various regions, and the urban commercial department will make timely judgments.Organize through trains at any time to send vegetables and other necessities to communities in need, so as to facilitate residents to buy them.

　　"Food is the most important thing for the people", and the daily life security of ordinary people is a huge matter, which cannot be stopped for a moment. This is the top priority of our work. People, cars, goods, markets, stores and warehouses are all indispensable. The business department will mobilize various forces to do the best to ensure the supply of living materials for citizens.

　　Do a good job in ensuring the daily medical service for people at risk of epidemic.

　　Wang Xiaoe, member of the Party Committee and spokesperson of the Beijing Municipal Health and Wellness Committee, introduced:In order to do a good job in ensuring medical service for epidemic-related risk personnel in high-risk areas, home isolation, centralized isolation, etc., and meet the daily medical needs of residents during the epidemic, the medical treatment and hospital prevention team closely followed the epidemic prevention and control situation, adhered to problem-oriented, closely coordinated with departments, coordinated medical resources, and further optimized and adjusted the daily medical service guarantee measures for epidemic-related risk personnel to ensure that medical services were not interrupted or delayed, and guaranteed people’s life safety and health.

　　The first is to implement classified protection and respond quickly to the needs of the masses for medical treatment.Arrange the situation of children, pregnant women, long-term dialysis patients, tumor radiotherapy and chemotherapy patients, critical patients and other key personnel involved in the epidemic, establish a work account, and inform critical patients to dial 120. For other non-critical patients who seek medical treatment daily, the medical team and community workers keep the telephone open for 24 hours to respond and solve the medical needs of residents in time.

　　The second is to establish a docking mechanism to meet the needs of medical treatment in various ways.Establish a docking mechanism between communities (villages), medical teams, community health service institutions and designated hospitals. When people involved in epidemic risk have daily medical needs, they will dock with medical teams or community health service institutions in time, and arrange medical personnel to meet medical medication and health needs through online diagnosis and treatment and drug delivery. For the epidemic-related risk personnel who need to go out for medical treatment, if it is really necessary to go to the designated hospital after judgment, the medical team or community health service institutions will coordinate and dock with the hospital.

　　The third is to improve the transshipment measures and smooth the channels for going out for medical treatment.In the closed control area, a mass medical support motorcade can be set up, and social vehicle assistance services can be provided when people involved in epidemic risk need to go out for medical treatment; For epidemic-related risk personnel who have the ability to drive by themselves or their families to accompany them to the hospital for medical treatment, they are encouraged to take private cars for medical treatment, unblock medical channels, and inform them well; For self-driving medical treatment, the bayonet in each control area should be released in time; Medical institutions should make good preparations for consultation, and medical institutions should not refuse to accept consultation because people involved in epidemic risk go to see a doctor on their own.

　　The fourth is to implement closed-loop management to ensure the safety of going out for medical treatment.People at risk of epidemic going out for medical treatment must do personal protection in the whole process, implement closed-loop management, and return to closed-loop immediately after medical treatment. Medical support vehicles that undertake the task of transferring people with epidemic risk should be dedicated to special vehicles, with physical isolation between the cab and the carriage, equipped with protective equipment in the vehicle, and the driver should strictly regulate and do personal protection to ensure the safety of going out for medical treatment and minimize the risk of social spillover.

CCTV News:According to the website of the US Navy Times, on April 8, local time, the first "Ford" of the newly developed "Ford" class aircraft carrier of the US military made its first self-powered voyage in Newport Port, and immediately began sea trials. So what is the difference between the latest aircraft carrier developed by the US military?

"Ford": Known as the world’s most advanced aircraft carrier

"Ford", 332 meters long and 40 meters wide, has a displacement of over 100,000 tons. It uses nuclear propulsion and has a speed of 30 knots. The number of carrier-based aircraft has reached more than 75, with a staffing of 4,550, and the total cost is as high as 13 billion US dollars.

　△ Figure/vision china

The overall dimensions of the "Ford" class aircraft carrier are not much different from those of the Nimitz class aircraft carrier (the active nuclear-powered multi-purpose aircraft carrier under the US Navy), but the performance has been significantly improved:

First, the degree of automation is further improved by using electromagnetic catapult instead of steam catapult and electromagnetic arresting device instead of hydraulic arresting device..

Second, the use of new nuclear reactors is more efficient..

Thirdly, it is possible to adopt a multi-functional phased array radar with single frequency band or a multi-functional radar with stronger anti-missile ability, so that the information level is higher.. 　

The sea trial of "Ford" will be carried out for several days, mainly focusing on the related tests of hull mechanical engineering and power system. After that, the US Navy will conduct flight operations and conduct a comprehensive test of the aircraft carrier’s flight deck.

　△ Figure/vision china

So, what is so outstanding about this so-called world’s most advanced aircraft carrier?Military expert Zhang Junshe believes that there are three main points.：

First of all, as the third-generation nuclear-powered aircraft carrier, Ford uses electromagnetic catapult, which has stronger ejection ability and more flexibility.You can eject a plane every 45 seconds25% faster than a Nimitz-class steam catapult. According to data research, Nimitz-class aircraft carrier can dispatch up to 160 carrier aircraft every day, and once electromagnetic catapult is used, the carrier aircraft dispatch of "Ford" aircraft carrier can reach 180.

Second, the power generation capacity is improved, which is three times higher than that of Nimitz-class aircraft carriers. The "Ford" aircraft carrier has two new and advanced nuclear reactors, each with a power generation capacity of 300 MW.In this way, we can meet the needs of using high-energy weapons such as rail gun and laser cannons in the future..

Thirdly, the setting on the deck is optimized. It will take time to finish the action of refueling and hanging bombs on carrier aircraft,From two hours to one hour..

Equipped with shipborne drones to subvert traditional operations

Another striking thing about the American "Ford" aircraft carrier is that it is equipped with an X-47B unmanned attack aircraft. It is the world’s first unmanned aerial vehicle that does not rely on manual remote control, but is independently controlled by artificial intelligence.

According to experts’ analysis, the X-47B unmanned attack aircraft has a long range and a large combat radius. Once it is put into operation, it can not only reduce casualties, but also carry out a deadly deep attack on the other side. Although the X-47B unmanned attack aircraft has many problems in the shipboard test, if it is used in conjunction with future manned fighters on the aircraft carrier, it will greatly improve the combat capability of the US Navy.

Military expert Zhang Jun society：

Former U.S. Defense Secretary Hagel once pointed out at the shangri-la dialogue Conference that once the X-47B unmanned attack aircraft successfully took off or landed on the aircraft carrier, it marked that the U.S. Navy entered a new aviation era, and it was also a milestone for the United States to gain military superiority.

Expert: The US military will rely more on aircraft carrier combat forces in the future.

In 2012, after the first nuclear-powered aircraft carrier Enterprise in the United States was retired, the US military has maintained a lineup of 10 Nimitz-class nuclear-powered aircraft carriers. After Trump took office, he put forward the slogan of restoring the number of aircraft carriers to 12. What does the joining of "Ford" mean to the US military?

Zhang Junshe, a military expert, believes that the main purpose of increasing the number of ships from the current 10 to 12 is to maintain the absolute superiority of the US Navy, especially compared with other countries. At present, the aircraft carriers owned by some countries in the world are much worse than the Nimitz-class aircraft carriers in the United States in terms of tonnage, the number of carrier-based aircraft and combat strength. In this case,The United States continues to develop aircraft carriers, of course, indicating that it will rely more on aircraft carrier combat forces in the future..

　　The Internet of Vehicles has once again taken a crucial step.

　　Recently, the "Implementation Plan for the Establishment of National Jiangsu (Wuxi) Vehicle Networking Pilot Area" was released to the public, marking the official launch of the construction of the first national vehicle networking pilot area in China. One day later, Miao Wei, Minister of Industry and Information Technology, and Wu Zhenglong, Governor of Jiangsu Provincial People’s Government jointly unveiled the first car networking pilot zone in China in Wuxi, Jiangsu. It can be said that the era of car networking has started.

　　At the vehicle networking security summit forum of the 6th National Cyber Security Publicity Week Sub-forum held recently in 2019, the vehicle networking security issue became a hot topic. Experts and scholars from the fields of vehicle networking and network security have conducted in-depth discussions on issues such as the development of vehicle networking security industry, security technology and application innovation, and actively made suggestions and suggestions.

　　Experts believe that the rapid development of the Internet industry is inseparable from the support of network security work, and the development of vehicle networking has also brought new challenges to network security. At present, the overall safety of the Internet of Vehicles is still in its infancy, which requires the joint participation of the automobile industry and the coordinated cooperation of related industries, so as to unite the strength of the industry, continue to increase R&D, innovation and investment from the aspects of technology, standards, management, even industrial system and personnel training, build a people-centered network security system of the Internet of Vehicles, and protect the security of terminal (vehicle) link data.

　　Accelerate the integration and innovation of 5G and car networking

　　In 2018, the car networking industry entered the fast lane. This year, China has successively issued a number of policy documents to promote the development of car networking.

　　In April 2018, the Ministry of Industry and Information Technology and other three departments issued the "Intelligent Networked Vehicle Road Test Management Specification (Trial)", which means that "unmanned" driving cars can be tested on more actual roads. In June 2018, the Ministry of Industry and Information Technology issued a series of documents entitled "Guidelines for the Construction of National Vehicle Networking Industry Standard System (General Requirements)", proposing that by 2020, an intelligent networked vehicle standard system that can support assisted driving and low-level automatic driving will be initially established.

　　In November 2018, the Ministry of Industry and Information Technology issued the "Regulations on the Management of Direct Communication Using 5905-5925MHz Frequency Band in Vehicle Networking (Intelligent Networked Vehicles) (Provisional)" to support the national special economic zones, new districts and free trade pilot zones to accelerate the construction of intelligent transportation systems.

　　On December 25, 2018, the Ministry of Industry and Information Technology issued the "Action Plan for the Industrial Development of the Internet of Vehicles (Intelligent Networked Vehicles)", clarifying that by 2020, a breakthrough will be made in the cross-industry integration of the Internet of Vehicles (Intelligent Networked Vehicles) industry, and intelligent networked vehicles with high-level autonomous driving functions will be applied in a specific scene scale, with the penetration rate of Internet of Vehicles users reaching over 30% and the infrastructure level of intelligent roads significantly improved.

　　Under the guidance of these policy documents, the development of China’s car networking industry has been further accelerated, and the industrial scale has been expanding.

　　On September 6, at the 2019 Expo Intelligent Transportation and Vehicle Networking Industry Development Summit Forum, the implementation plan for the establishment of the national Jiangsu (Wuxi) Vehicle Networking Pilot Area was officially released. On September 7, Miao Wei and Wu Zhenglong jointly unveiled the first car networking pilot zone in China in Wuxi, Jiangsu.

　　Miao Wei proposed to combine the commercial deployment of 5G, give full play to China’s foundation and advantages in network technology, pilot demonstration, industrial integration, institutional mechanisms, etc., and accelerate the integration and innovation of 5G and car networking; Focus on the "stuck neck" technical links such as automotive chips, computing platforms and in-vehicle operating systems, achieve breakthroughs one by one, and support qualified regions and enterprises to try first; Promote the improvement of relevant laws and regulations, speed up the construction of the vehicle networking pilot area, strengthen the exploration of management mechanism and operation mode, improve the level of safety protection technology, and ensure the healthy development of the vehicle networking industry.

　　Some experts believe that the development of the car networking industry is conducive to improving the level of car networking and intelligence, realizing automatic driving, developing intelligent transportation, and promoting information consumption. It is of great significance for China to promote supply-side structural reform, promote the construction of a manufacturing power and a network power, and achieve high-quality development.

　　Give play to the key role of network security

　　The development of car networking is a profound change involving the value chain, industrial chain and innovation chain. During the 13th Five-Year Plan period, China will take scientific and technological innovation as the guide and intelligent networking as the main direction, and strive to create new formats and new kinetic energy, and promote the transformation, efficiency and upgrading of the automobile industry, so as to achieve the goal from big to strong.

　　Zhao Zhiguo, director of the Network Security Administration of the Ministry of Industry and Information Technology, believes that "the Internet of Vehicles is a new thing, with a new industrial form, a large industry span and a wide range of applications. Its perfection and development require vehicle companies, parts research and development companies, Internet companies, universities, and scientific research institutions to jointly explore and work together."

　　"Without network security, everything is impossible." According to Shen Changxiang, an academician of China Academy of Engineering, safety is the premise of development, and development is the guarantee of safety. Network security threats and protection are eternal themes, and cyberspace is much more fragile than imagined. The traditional "blocking and killing" has been difficult to deal with attacks, so it is necessary to establish a computing framework of active immunity. By building a triple protection framework of active immunity supported by a trusted security management center, the active immune computing model with measurable and controllable calculation results and coexistence of protection and calculation can be achieved. Shen Changxiang said frankly, "The Internet of Vehicles is a typical Internet of Things. It is necessary to simplify complex problems with the hierarchical protection safety management center architecture and form a safety management center according to the hierarchical protection requirements."

　　With the advent of the 5G era, is the Internet of Vehicles a joy or a worry? Wang Yongjian, a researcher at the Internet Emergency Center, said that the Internet of Vehicles in the 5G environment faces five major security threats: intelligent networked vehicles, mobile intelligent terminals, Internet of Vehicles service platforms, wireless communication in the Internet of Vehicles, data security and privacy protection in the Internet of Vehicles. The security risks introduced by 5G generalized access in wireless communication mainly include: traffic attack, identity forgery and malicious interference.

　　To this end, Wang Yongjian suggested that in terms of technical monitoring means, it is necessary to study the intelligent abnormal traffic monitoring mechanism based on deep learning and other technologies, improve the network security protection capability of the Internet of Vehicles, and provide monitoring and early warning functions and network control functions; Based on the 5G authentication framework and communication encryption algorithm, a trusted "man-vehicle-road-cloud" collaborative communication is built to realize timely identification and alarm of unauthorized access. At the same time, the monitoring and positioning technology of abnormal strong interference is studied, and the monitoring system is intelligently arranged based on roadside facilities to monitor important frequency bands in real time, so as to realize the cooperative positioning of abnormal interference sources in satellite navigation and other systems.

　　Build a network trust support platform together.

　　How to deal with the security risks faced by the Internet of Vehicles? Experts attending the meeting put forward suggestions from many angles.

　　"The car network security trust system is an important means to solve the network security problem of the car network." Zheng Jihu, director of the data resource center of China Automotive Technology and Research Center Co., Ltd., said that in order to solve the problems faced by the automobile industry in the process of establishing a network trust system, China Automobile Center has jointly established a network trust support platform for the automobile networking with relevant enterprises, universities and research institutes to provide network security for the intelligent and networked development of the automobile industry.

　　It is worth noting that "China Internet of Vehicles (Intelligent Networked Cars) Network Trust Alliance" was launched at the forum. According to Zheng Jihu, the alliance aims to build a better trust support platform for the Internet of Vehicles (IoT), and to connect the upstream and downstream industrial chains of the IoT trust system.

　　Yang Bin, senior vice president of Tianrongxin Company, pointed out that "to do a good job in the security protection of the Internet of Vehicles, we need to learn from the protection technology of IT network security, combine the business scenarios of the Internet of Vehicles, and adopt a variety of protection technologies to work together."

　　"For example, through authentication and encryption technology, the trusted identity authentication and communication encryption transmission of the in-vehicle network, the car and the cloud, the car and the mobile phone can be realized, and attacks such as command cracking, replay attacks, identity forgery and data theft can be prevented." Yang Bin said, through the vehicle intrusion detection technology based on white list, combined with security incident reporting and cloud strategy distribution, the attack detection such as abnormal traffic and abnormal message identification in the vehicle can be realized.

　　For another example, the in-vehicle security domain is isolated through the in-vehicle security gateway, so as to realize access control between key interconnected components in the vehicle, depth detection of CAN messages, security audit, intrusion prevention, etc., and realize the security protection of the in-vehicle network boundary.

　　Regarding how to do a good job in the safety of car networking, Zhao Zhiguo put forward five suggestions: First, fully understand the importance and urgency of car networking safety; The second is to accelerate the breakthrough of the core technology of vehicle networking security; The third is to promote the improvement of the security system of the Internet of Vehicles; The fourth is to strengthen the guarantee of talent team; Fifth, strengthen international exchanges and cooperation.

　　Guo Yansong, deputy director of the Technology Center of Great Wall Motor Co., Ltd., called for the establishment of industry-recognized automotive network security data; At the same time, formulate a car network security solution suitable for China’s national conditions; In addition, it is necessary to speed up the formulation of standards, certification and access systems so that enterprises in the industry can have evidence to follow.
