　　Developing autonomous driving technology is an important content of building a transportation power. In recent years, with the rapid development of new technologies such as artificial intelligence, 5G and big data, the application of autonomous driving technology in the field of transportation has been accelerated, and the rapid iteration from closed site testing to road testing and from pilot demonstration to commercial trial operation has been realized.

　　The Ministry of Transport recently issued the "Guide to Transportation Safety Services for Self-driving Vehicles (Trial)" (hereinafter referred to as the "Guide"), which made it clear for the first time from the national policy level that intelligent networked vehicles can be used for transportation business activities, and pressed the "acceleration button" for the commercial application of self-driving technology in China.

　　What is the development of autonomous driving technology at present? How to improve the safety guarantee ability of autonomous driving? The reporter interviewed the relevant person in charge of the Ministry of Transport and relevant experts.

　　The market scale is growing rapidly, and it is steadily moving towards commercial application.

　　"With the joint efforts of all parties, in recent years, China’s autopilot-related industries and market scale have shown a rapid growth trend, and autopilot technology has steadily moved from testing and demonstration to commercial application." Zhang Jinhua, chairman of China Automotive Engineering Society, introduced.

　　The industrial development environment continues to improve. At present, 17 national-level test demonstration zones, 7 national-level vehicle networking pilot zones and 16 "Shuangzhi" pilot cities have been built nationwide, with a cumulative open test road of over 22,000 kilometers and a cumulative test mileage of over 70 million kilometers. Beijing, Shanghai, Guangzhou, Shenzhen and other cities have introduced policies to allow self-driving cars to engage in commercial trial operation of urban public buses, taxis, logistics and distribution in specific areas and at specific time periods, and the application scale has been expanding.

　　In Shunyi District, Beijing, hundreds of bright yellow automatic delivery vehicles appeared in the streets and lanes, waiting for traffic lights side by side with pedestrians, or avoiding other vehicles safely on the road. "After years of iterative upgrading, unmanned delivery vehicles can not only ‘ Get ’ , can provide consumers with ‘ Send it quickly ’ Service experience. " The person in charge of the automatic delivery department of Meituan said that at present, in Shunyi, the daily delivery orders of automatic delivery vehicles of Meituan have reached thousands.

　　In the Economic Development Zone of Wuhan, Hubei Province, open the "radish run" taxi software, and you can quickly call an unmanned self-driving car by setting the starting point and the ending point. Passengers click "OK" on the back screen, and the vehicle can travel according to the established route. "The fisheye camera and laser sensor on the roof device can help the vehicle avoid obstacles accurately and automatically adjust the speed according to the road conditions." According to the person in charge, 300 driverless cars have been put into operation since the unmanned self-driving travel service was opened in Wuhan in August 2022, covering a population of over 4 million.

　　The application of industry innovation has accelerated. Scene-level autonomous driving solutions have accelerated to maturity, and some autonomous driving products have reached the conditions of mass production application, and have been applied to transportation service scenes such as urban travel and freight logistics on a certain scale, and new formats such as autonomous parking service and unmanned distribution have emerged continuously. At present, there are more than 200 self-driving city buses, more than 1,500 self-driving taxis and about 1,000 self-driving trucks in China. Baidu Apollo autopilot test has a total mileage of more than 78 million kilometers, and its travel service covers more than 10 cities.

　　With the continuous expansion of market scale, it is urgent to strengthen industry norms. "At present, the basic requirements for using self-driving cars for transportation operations are still unclear, which is not suitable for the healthy and orderly development of self-driving cars, and the safety pressure is increasing." The relevant person in charge of the Transportation Service Department of the Ministry of Transport said that the Guide clarified the basic requirements for using self-driving cars to engage in transportation business activities under the framework of current laws and regulations, and guided the healthy development and standardized application of self-driving cars in the field of transportation services in an orderly manner while ensuring transportation safety.

　　Build a security system to provide compliance for business activities.

　　Transportation services are related to the national economy and people’s livelihood. Continuously improving the safety and security capability is the primary goal of transportation services, and it is also the basic requirement for the promotion and application of self-driving cars in transportation services. Sorting out the measures in the Guide, the word "safety" runs through.

　　"Adapting to the development trend of autonomous driving, the Guide focuses on ensuring the transportation safety of autonomous vehicles. Under the condition of meeting the requirements of relevant departments for the access and road traffic of autonomous vehicles, it puts forward requirements for the production conditions and qualifications of transportation operations, dynamic supervision and emergency handling of vehicle operation, and operational supervision, and guides the transportation safety services of autonomous vehicles in all directions and in the whole chain." Zhang Jinhua said.

　　In terms of technical standards, the Guide clarifies the technical requirements for self-driving cars, emphasizing that "self-driving cars engaged in taxi passenger transport, road passenger transport and road cargo transport should also meet the requirements of technical standards for operational motor vehicle safety in the transportation industry". "This move has achieved the connection with the management boundary of self-driving cars in the departments of industry, information and public security." Li Bin, vice president of the Highway Research Institute of the Ministry of Transport, said.

　　In terms of personnel allocation, the Guide specifically puts forward the concept of "safety officer" in view of the safety problems during driving.

　　"The on-board driver or operation safety guarantee personnel of the self-driving car is ‘ Safety officer ’ 。” Li Bin said that the Guide fully considers the business models of self-driving transportation with different formats, and provides for the allocation, skills and qualification requirements of safety officers engaged in different transportation business activities by classification on the premise of ensuring safety. Among them, in view of the application scenario of fully self-driving cars engaged in taxi passenger transport, the form of personnel support for remote safety officers is put forward in particular, and it is clear that "with the consent of the people’s government of the district and city, remote safety officers can be used when operating in designated areas, and the ratio of people to vehicles of remote safety officers should not be less than 1: 3".

　　"Overall, the Guide has built a safety guarantee system from six aspects: safety production system, transportation safety guarantee, running state information management, vehicle dynamic monitoring, safety notification and emergency response." Li Bin believes that under the premise of being consistent with the current road transportation management, the Guide fully combines the new characteristics of self-driving car transportation, and provides compliance for self-driving cars to engage in road transportation business activities safely.

　　Classified scenarios provide normative guidance to accelerate the application of technology.

　　As a new technology, autonomous driving has been widely used in various transportation service scenarios. Different scenarios have different design and operation conditions, different security risks and different risk level requirements. In order to further ensure safety, "classified policy" has become a highlight of the Guide.

　　The Guide clarifies the application scenarios of self-driving cars to carry out road transport services. For urban public buses and trams, related passenger transport business activities can be carried out under the scenes of physically closed, relatively closed or simple road conditions with fixed lines and controllable traffic safety; For taxis, passenger transport business activities can be carried out in the scene of good traffic conditions and controllable traffic safety; At the same time, self-driving cars are prohibited from engaging in road dangerous goods transportation business activities. At the same time, the Guide clarifies the requirements for "self-driving transport operators", and taxi passenger transport and road passenger transport should be insured with carrier liability insurance according to law.

　　"Standardizing the application of self-driving cars in the field of transportation services by classification, scene and level will effectively guide all kinds of transportation service business activities to carry out self-driving applications, effectively ensure the safety of self-driving transportation services, and promote the healthy and orderly development of commercial applications of auto-driving." Wang Advanced, vice president of the Research Institute of the Ministry of Transport, said.

　　The overall scale of China’s automobile industry remains in the forefront of the world, and the production capacity and application technology level have been greatly improved. As an important breakthrough to improve the level of industrial intelligence, autonomous driving has been valued and supported by relevant departments.

　　In 2020, the Ministry of Transport issued the Guiding Opinions on Promoting the Development and Application of Road Traffic Autopilot Technology; In 2021, the Ministry of Industry and Information Technology issued the Opinions on Strengthening the Access Management of Intelligent Networked Automobile Manufacturers and Products; In November 2023, four ministries and commissions, including the Ministry of Industry and Information Technology, issued the Notice on Launching the Pilot Work of Intelligent Networked Vehicle Access and Road Access, which covered the key links of vehicle use, such as production access and road management of automobile products, and the management policies for the production and use of self-driving vehicles were gradually established … … In recent years, various ministries and commissions have accelerated the research on policies related to the commercial application of autonomous driving and issued a series of policy documents.

　　"The increasingly perfect industrial development environment has made it possible for self-driving cars to accelerate their application in transportation services." Wang Advanced said that the release of the Guide has established a safe bottom line for the application of self-driving cars, and also left enough room for the innovative application of autonomous driving, which will further promote the application of autonomous driving technology in the transportation field.

　　Upward oblique push-ups

　　Standard push-ups

　　Downward oblique push-ups

　　L extension

　　Flexion and extension of sitting arm

　　Hip bridge

　　Alternate forward arrow squat

　　Moderate exercise can not only maintain good physical function and enhance the athletic ability of skeletal muscles, but also help officers and men to relieve anxiety and maintain an optimistic and positive attitude towards life. Here are some recommended fitness exercises that can be done at home.

　　Practice chest muscle movements — — Push-ups According to the difficulty of the action, it is divided into upward inclined push-ups, standard push-ups and downward inclined push-ups. When doing push-ups, be careful not to collapse, hips or shoulders. Upward inclined push-ups are suitable for beginners, while downward inclined push-ups are suitable for people who can easily do standard push-ups. It is suggested that each group should have 10-15, with 3-4 groups at a time.

　　Stimulate back muscle movements — — L-shaped extension L-shaped stretching can stimulate back muscles, enhance back muscle strength, maintain the stability of thoracic vertebrae, relieve muscle tension caused by long-term desk work and reading, and make people stand tall and straight. It is suggested that each group should have 10-20, with 2-4 groups at a time.

　　Practice upper arm movements — — Sitting posture, arm flexion and extension. Flexion and extension of sitting arm can exercise triceps brachii, improve arm strength and protect shoulder joint. This action can be done by the bed, in front of the TV cabinet or with a stable chair. It is suggested that each group should have 10-20, and each group should have 2-3.

　　Practice hip muscle movements — — Hip bridge. The gluteal bridge can directly stimulate the gluteus maximus, which is helpful to stabilize the hip joint and improve the forward inclination of pelvis. At the same time, it can also activate the deep stable muscle group, strengthen the core and prevent low back pain. Be careful not to use arm strength to prop up your body when doing this action. It is suggested that 10 should be a group and 2 groups should be trained.

　　Lower extremity motor ability training — — Alternate forward lunges. Strong lower limb strength can improve the flexibility and stability of body movement. Training the exercise ability of lower limbs can not only burn fat, but also strengthen joints and reduce the chance of injury during exercise. When doing this action, be careful that the knee joint does not exceed the toe, do not buckle internally, and keep in line with the toe direction to avoid putting pressure on the knee joint. It is suggested that 10 should be a group and 2 groups should be trained.

　　Core muscle group training — — Flat support. Plate support is a static exercise, which strengthens muscle strength by exercising core muscle groups, maintains the stability of spine, pelvis and scapula, and shapes the lines of waist, abdomen and buttocks. When doing flat support, be careful not to bend your back, bow your back or get on your hips. At the beginning, you can aim at supporting for 1 minute. If you can’t finish, you can increase the distance between your feet and reduce the difficulty.

Chatelet Opera House, Golden Globe Festival. When Beckham handed the Golden Globe Award to Messi, the audience stood up and gave applause!

This is a tribute to the ball king. During the performance inspection period of the 2023 Golden Globe Awards (from August 1, 2022 to July 31, 2023), Messi contributed 42 goals and 26 assists, as well as the World Cup champion, World Cup MVP and Ligue 1 champion trophy. The 8 th Golden Globe Award is in hand, and Messi leads alone in the century-old football.

Messi smiles and accepts the award, and we will think of Cristiano Ronaldo, one of the peerless double arrogance.

38-year-old Cristiano Ronaldo, will he feel "injured"? Cristiano Ronaldo is really a little injured-Cristiano Ronaldo, who played successfully in Riyadh, suffered a slight bruise on his ankle, which did not affect his play. The Golden Globe Award is 5-8 behind Messi, and Cristiano Ronaldo, who is competitive, is hard to quiet inside.

Sports media all over the world gave the front page headline of the cover to Messi, who was holding the Golden Globe Award, and the praise was overwhelming. At this time, Riyadh, Saudi Arabia is already late at night, and Cristiano Ronaldo may have fallen asleep, preparing for the quarter-final of Saudi Arabia’s "Guardian Cup of Two Holy Temples" on the second day, or the quarter-final of Saudi Arabia’s King’s Cup, without much attention.

At this moment, we can feel the fact more: the dispute between the peerless and arrogant has ended.

On December 10, 2022, Portugal was eliminated in the quarter-finals, and Cristiano Ronaldo said goodbye with tears; On December 18, 2022, Messi won the sacred World Cup under the crowd, and the global media all exclaimed that "the new ball king was born". In just 8 days, the peerless double pride has embarked on a different track, and its historical position has been frozen.

In the twilight of his football career, Messi made a great leap to lift the World Cup and achieve the greatest goal. C Ronaldo left regrets and explained disappointment and unwillingness with tears. On the night of the Golden Globe, Messi was crowned with the Golden Globe Award for the eighth time-this is the continuation of Messi’s joy and Cristiano Ronaldo’s sadness in the World Cup, which really ended the dispute between the two arrogance.

The era of double arrogance PK has ended, and the era of Messi and Ronaldo has also ended.Messi in Miami and Cristiano Ronaldo in Riyadh are veterans running in the afterglow of sunset, and the direction of sunset is the time to hang up your boots. This day will come eventually, and watch and cherish it.

The future belongs to Bellingham and Harland. Premier League, Champions League, La Liga, this is the sun-like stage, the center of world football. The dispute between Messi and Cristiano Ronaldo is no longer the mainstream-although the two veterans can still contribute to the monopoly level of heat and topic, the gods also have the end of the day, and next year’s Golden Globe Award is likely to completely turn over the page of double arrogance.

　　Air China flight CA1524 flew normally today (July 11th) after the clear sky turbulence, but the aircraft type changed.

　　The Paper reporter learned from Fei Changzhun platform that on July 11th, Air China flight CA1524 will still fly normally, and it is scheduled to take off from Shanghai Hongqiao Airport at 14: 45, and it is expected to land at Beijing Capital International Airport at 16: 36, with Boeing 747-89L.

　　On July 11th, China International Airlines issued a notice in its official Weibo: On July 10th, 2023, Air China flight CA1524 (Shanghai-Beijing), model A330-300, was suddenly bumped by the clear sky during the flight, and the crew and crew handled it according to the procedures, making every effort to safeguard the safety of passengers, and one passenger and one flight attendant were injured in the process. The flight landed normally at 17: 18, and Air China arranged a special person to accompany the injured passengers and flight attendants to the hospital for treatment.

　　Air China official micro-release notice Weibo screenshot

　　On the 11th, the band @SummerVapour Summer Solstice Dream released Weibo, saying that he was on flight CA1524 at that time, and he personally experienced the thrilling scene of the plane bumping. According to its profile in Weibo, SummerVapour Summer Solstice Dream Band consists of three people.

　　At noon on the 12th, Weibo replied to the The Paper reporter that the passengers were blinded at first when the plane was bumpy, and only after the plane was stable did everyone slow down and start looking for things, and young people helped the elderly with mobility difficulties. "Thanks to Air China flight CA1524, the professional crew, and the passengers who abide by the regulations, everyone was surprised and had an unforgettable flight."

　　In addition, Weibo also shared some warm-hearted clips at the time of the incident. After the turbulence, the crew broadcast for medical practitioners. The fans of star @ Kid-Lil Ghost had medical qualification certificates, and stood up first to help the injured passengers. When landing, @ Boxing World Li Jingliang soothed the passengers around and took everyone to applaud the crew. After landing smoothly, the musicians of various bands on the plane got up and squatted to help some people with mobility difficulties find lost mobile phone headphones and other items.

　　This incident has caused many netizens to pay attention to the word "clear sky bumps".

　　According to @ Central Meteorological Observatory, clear-sky turbulence usually occurs on sunny days, which is caused by clear-sky turbulence. Turbulence is caused by the irregular flow of the atmosphere. When encountering turbulence, the plane will bump rapidly, and in severe cases, the plane may temporarily lose control. Because it is not accompanied by obvious weather phenomena, it is difficult to observe and detect, which poses a great threat to flight safety.

　　According to the Beijing Evening News, in June, 2017, China Eastern Airlines flight MU774 from Paris to Kunming, China, also had a clear sky bump, causing dozens of passengers on board to be injured to varying degrees. At that time, Wu Mingxiang, a senior captain of Shenzhen Airlines, said: "We can only make a comprehensive analysis of the forecast through the high-altitude weather map before taking off, but the accuracy is low. In fact, flying to an area that may be bumpy is not necessarily bumpy, and it is also related to the flight altitude, so ‘ The clear sky is bumpy ’ It is not easy to predict. It is recommended that passengers fasten their seat belts when sitting in their seats. After all, the flight situation is complicated. Planes are different from cars, and the impact force before and after is not as big as that up and down, so wearing a seat belt can prevent people from flying and being injured. Generally speaking, people who are injured by bumps in the air are not wearing a seat belt. "

　　According to a recent report by Xinhua News Agency, a British study shows that in recent decades, the probability of aircraft encountering clear sky bumps during flight is increasing, which is inseparable from global warming under climate change.

　　Chen Jianguo, a senior pilot, told The Paper that there is no need to panic excessively in the event of bumps. Remember that keeping your seat belt fastened on the plane is the safest preventive measure, regardless of whether the seat belt indicator is on or not.
