350 kilometers per hour, operating mileage of 30,000 kilometers. The rapid development of China’s high-speed railway has become a shining “China business card”, and China’s high-speed rail technology is constantly improving. Among them, self-driving will be launched at the end of this year, the smart Beijing-Zhang high-speed rail promotion. On the 25th, five high-speed railway science and technology workers from China National Railway Group Co., Ltd. invited by the State New Office met with Chinese and foreign journalists, said Yang Bin, director of the Engineering Management Center of China National Railway Group Co., Ltd. and commander of the Beijing-Hung High-speed Railway Construction Command.

Take a self-driving high-speed train at the end of the year
In the second half of 2018, China Railways organized an independent intelligent high-speed rail integrated system test in Beijing-Shen high-speed railway, focusing on intelligent equipment, intelligent construction, intelligent operation and other aspects of a total of 29 tests, with the autonomous train operation control system test marked by the self-driving function of high-speed rail is one of the most important test projects.
Self-driving system is one of the key core systems of intelligent railway, which is of great significance for reducing driver’s labor intensity, improving driving safety, enhancing passenger experience and green energy saving.
Train safety is improved, train punctuality rate is improved, passenger comfort is improved, driving efficiency is improved, driver’s labor intensity is reduced, and the energy consumption of train traction is reduced. System function can be summed up as four automatic one linkage: station automatic departure, automatic operation of the interval, automatic stop at the station, automatic opening of the parking, door and platform door linkage control. The self-driving test of the Revival motor vehicle group at 350km/h was a success, and the experimental data showed that the parking error of the train set was controlled within 10cm, the energy saving index was about 15%, and the train punctuality rate was theoretically 100%.
Self-driving will be launched at the end of this year, the smart Beijing-Zhang high-speed rail promotion. At that time, you can take the self-driving high-speed train.
In 2016, China’s Pearl River Delta city in the world to achieve the first 200km/h of self-driving, in 2018 in the Beijing-Shenzhen high-speed rail test to achieve the first high-speed rail self-driving speed of more than 300km/h. China’s railways have taken the lead in autonomous driving of high-speed rail.
China Railways has equipped more than 560 groups of Revival

“Now, China Railway has been equipped with more than 560 sets of Revival, Revival is also moving towards serialization, intelligent, branding direction. “As a railway science and technology worker involved in research and development, Zhang Bo feels sincerely proud and proud.
Zhang Bo, deputy director of the locomotive and vehicle research institute of China Railway Science Research Institute Group Co., Ltd., and head of the research and development team of the Academy of Railwayscience Revival.
Superior quality and performance, Revival has become China’s high-end equipment manufacturing brand. In July 2016, The Revival successfully crossed and re-connected at 420 km/h in Zhengxu High-speed Railway, the first time in the world that high-speed rail has been operated. In September 2017, The Revival achieved commercial operation of 350 km/h on the Beijing-Shanghai high-speed railway.
Since graduating from Shanghai Railway University in 1997, Zhang Bo has been engaged in locomotive research and research, is a member of the overall technology and core system research and development team of Revival, and has participated in the whole process of research and innovation of Revival at 350 km/h.
Now we’re using Beidou satellites for control measurements.
Wang Changjin, Deputy Chief Engineer of China Railway Design Group Co., Ltd. and Master of National Engineering Survey and Design
“Now we use Beidou satellite sattos for control measurements, remote sensing and mapping with domestic high-scoring satellites, topographic mapping with airborne lidar and drones, and geological surveys with earth exploration.” “China Railway Design Group Co., Ltd. Deputy Chief Engineer, national engineering survey and design master Wang Changjin is very impressed.
High-speed rail construction must first survey, then can be designed, the third step can be built, and finally is the operation. Wang Changjin and his team have created a technical standard system for the measurement of china’s high-speed railway precision engineering, which is one of the key technologies for the success or failure of high-speed railway construction.
Wang Changjin, who has been engaged in railway survey and design work for 33 years, has witnessed the dramatic changes in the railway survey and design in China.
Thirty-three years ago, just participated in the work of Wang Changjin, in the railway survey, the most common means is the use of “latitude, large plate plus flat” manual mapping topographic map, the use of hand-shake computer, T-size ruler plus curve plate design, manual drawing. “The efficiency is very low, and the railway construction is naturally not fast. Wang Changjin said that today, railway design means from manual mapping to computer-aided mapping, from two-dimensional design to three-dimensional design, from single-disciplinary single-person design to multi-professional collaborative design, railway survey design efficiency has increased dozens of times.
Wang Changjin participated in the survey and design of the first high-speed railway with 350 kilometers per hour in China, the Beijing-Tianjin intercity railway, the first highest technical standard and the fastest high-speed railway- the Beijing-Shanghai high-speed railway, and the first high-speed railway in the high-cold region- the Hada high-speed railway. Counting these achievements, Wang Changjin felt that he had caught up with the good times.
Build a high-speed rail like a building block
“At present, China’s railway construction error has reached the millimeter level, the construction process, the work law requirements are very high. Yang Bin revealed that the Beijing-Hung intercity railway is currently under construction, actively exploring the study of the new era of railway construction development level of intelligent chemical equipment and supporting technology, China’s first section of high-speed rail assembly integrated bridge main project has been successfully achieved.
This assembly-type integrated bridge construction technology innovation, it is also known as “building high-speed rail like building blocks.”
“Mainly the bridge project pile foundation, pier, cap, box beams and bridge wall protection wall, cable slots, etc. are in the factory for professional design, segmented standardization of prefabrication, and then shipped to the site assembled. Yang Bin said that this technology is a major breakthrough in the traditional way of building bridges in railway construction, reflecting the construction concept of green, efficient, high-quality, safe and humane high-speed railway construction in China today.
“I and the research team, independent research and development of 12 sets of work equipment, to ensure accurate position. Yang Bin said that in the process of research and application of high-speed railway bridge assembly integrated key technology, the construction of high-speed railway assembly-type integrated construction system, formed three industrial methods, prepared five standards, applied for a number of patents.
