The New Breakthrough of Automatic Driving Technology Is Applied in the Field of High-speed Rail for the First Time

In today's intelligent technology, automatic driving technology will be applied in the field of high-speed rail for the first time. It is reported that the intelligent technology of Beijing Zhangjiakou high-speed railway (Beijing Zhangjiakou) has achieved comprehensive coverage, and the automatic driving technology of high-speed railway with a speed of 300-350 kilometers per hour will be applied in Beijing Zhangjiakou high-speed railway for the first time. In the future, the intelligent multiple unit train running on Beijing Zhangjiakou high-speed railway can automatically monitor and alarm the natural environment such as wind level, rainfall and snow depth, so as to ensure the real-time boarding of gale alarm information.

On October 27, at the 14th China International Modern Railway Technology and equipment exhibition, He Huawu, academician of the Chinese Academy of engineering, vice president of China Association of science and technology and special technical adviser to the general manager of China Railway Corporation (hereinafter referred to as "China Railway General Manager"), mentioned in his speech that China has been in Guanhui, Dongguan and Dongguan in the Pearl River Delta Two inter city railways with a speed of 200 km / h between Foshan and Zhaoqing have opened automatic train operation technology (ATO). The automatic train operation technology of high-speed railway with a speed of 300-350 km / h is still blank in the world. This technology will be applied for the first time in Beijing Zhangjiakou high-speed railway.

Beijing Zhangjiakou high speed railway is an important part of the fast track from Beijing to the West and North and the Beijing Tianjin Hebei intercity railway network. It is a major transportation infrastructure for the 2022 Beijing Winter Olympic Games. China Railway Corporation proposes to build Beijing Zhangjiakou high-speed railway into a "high-quality project and intelligent high-speed railway".He Huawu comprehensively introduced the intelligent coverage level of Beijing Zhangjiakou high speed railway, which is reflected in three aspects: intelligent equipment, passenger oriented intelligent service technology and operation and intelligent construction.He Huawu revealed that on the Beijing Zhangjiakou high-speed railway, the future will be based on the "Fuxing" Chinese standard EMU platform to develop intelligent EMUs with self sensing of working status, self diagnosis of operation faults and safety oriented self decision-making.

In terms of power supply system, the vehicle will be equipped with an intelligent power supply system composed of intelligent power supply equipment, intelligent power supply dispatching, intelligent power supply operation management and communication network to realize the functions of intelligent fault diagnosis, early warning, self-healing and reconstruction, and form a health assessment system of power supply system.The dispatching system will build an intelligent dispatching command system of high-speed railway based on artificial intelligence to realize the functions of intelligent dynamic dispatching, intelligent collaborative control, intelligent transfer dispatching and intelligent fault diagnosis, so as to optimize the overall train dispatching efficiency of the road network, improve the emergency decision-making and processing capacity of the system, and improve the operation efficiency and passenger satisfaction.He Huawu also said that in the future, the intelligent EMU trains running on the Beijing Zhangjiakou high-speed railway can automatically monitor and alarm the natural environment such as wind level, rainfall and snow depth, so as to ensure the real-time boarding of gale alarm information. It can also realize earthquake early warning and automatic emergency disposal, and automatically alarm and prevent illegal intrusion along the line.

The future operation and maintenance of Beijing Zhangjiakou high-speed railway EMU trains will also be intelligent. He Huawu said that in the future, advanced technologies such as big data, in-depth learning, fault prediction and health management (PHM) and augmented reality will be applied to realize the whole process management of technical equipment, improve the intelligent level of maintenance of technical equipment such as EMUs, reduce the full life cycle cost of equipment and improve the transportation efficiency and safety level.China Railway Corporation will launch a number of intelligent services for Beijing Zhangjiakou high speed railway, including: improving 12306 website and self-service facilities; Support multi language foreign bank card payment; Expansion ticket forms (regular ticket, connecting ticket, frequent travel ticket, etc.); It can realize electronic ticket, face brushing, station entry and ticket checking; Provide travel planning and information services, as well as WiFi full coverage and in station navigation services; It can realize baggage check-in and synchronous security inspection, and provide personalized and barrier free services.On the other hand, the high-speed railway station closely related to passengers will also realize intellectualization: the station provides intelligent guidance and self-service facilities, which can realize the intelligent perception of station operation (illegal intrusion identification, abnormal detection of crowd aggregation and diffusion, environmental monitoring and regulation, etc.), realize the intelligent monitoring and management of station equipment, and is equipped with air source heat pump Energy saving and environmental protection technologies such as closed pneumatic conveying of waste.

It is reported that at present, the Beijing Zhangjiakou high-speed railway project is under construction. It also has intelligent application in project construction management and infrastructure detection and monitoring.For example, the construction of Beijing Zhangjiakou high-speed railway project takes BIM GIS technology as the core, comprehensively applies the new generation of information technologies such as Beidou satellite positioning, smart IOT and mobile Internet, completes the automatic collection and information interconnection of data in the construction process and test site, and constructs a full-life traceable closed-loop management system and comprehensive management platform for project construction quality.In the intelligent detection and monitoring of infrastructure, it can realize the safety monitoring of key engineering structures such as Badaling Great Wall underground station, intelligent perception and safety early warning of key turnout status, and intelligent data analysis, processing and application.
