Beijing Zhangjiakou High speed Railway is the world's first intelligent high-speed railway with a speed of 350 kilometers per hour, and it is also an important transportation infrastructure to support the success of the 2022 Winter Olympics in Beijing. Since its construction, Beijing Zhangjiakou High speed Railway has formed 67 application and innovation achievements, and carried out 12 intelligent upgrading works; Relying on the key project of the national key research and development plan "Science and Technology Winter Olympics" - the key technology and demonstration project of Beijing Zhangjiakou high-speed rail intelligent service, we will focus on the three goals and tasks of passenger intelligent travel, high-speed rail operation safety, and humanistic winter Olympics service, so as to provide high-quality modern railway transportation service guarantee for the successful holding of the Beijing Winter Olympics. Recently, Ma Jianjun, the second person in charge of Beijing Zhangjiakou High speed Railway Intelligent Service Key Technology and Demonstration Project, and the deputy general manager of China Academy of Railway Sciences Group Co., Ltd., visited the People's Ice Snow · Ice Snow Technology Talk, The important scientific and technological achievements of intelligent service of Beijing Zhangjiakou high-speed railway are introduced.

Ma Jianjun introduced that the intelligent high-speed rail service has three goals. In terms of ticketing services for the Winter Olympics, it is the first to open 12306 English website and its APP launch 12306 English customer service specialist We also developed a Chinese and English automatic ticket vending machine to support foreign bank card payments; The second is to launch time ticket and fixed ticket of Beijing Zhangjiakou high-speed railway ； Third, development Commemorative Winter Olympics featured train tickets. In terms of ticket purchase services for special groups, 12306 Love Edition was launched Services, providing services such as large font, large icon and one button operation for the elderly, It also provides voice screen reading and broadcasting services for the visually impaired. For the physical handicap Obstructive, supports custom gestures, and realizes simple operation and convenient interaction Ticketing service. At the same time, manual remote assistance ticket selling is also set at the station Equipment to help passengers purchase tickets by audio and video.

Humanistic Winter Olympics services are implemented in terms of passenger travel Now waiting, taking the train and leaving the station are all links. At the passenger waiting link, Jingzhang The stations along the whole high-speed railway line provide international voice navigation and reality for Chinese and foreign passengers Time guided service. At the passenger boarding link, the whole line of Beijing Zhangjiakou High speed Railway was firstly arranged 5G communication network, and developed 5G based train multimedia Olympic information service Service system, providing technical support for 5G HD broadcast and smart game watching; Secondly, the Olympic type intelligent multiple units developed by the railway department have realized high-speed railway The function of parking train seats and barrier free wheelchairs and the storage of ski equipment In other words, it provides service guarantee for supporting facilities dedicated to athletes and the disabled. In the process of passenger departure, research It has temperature measurement, face recognition, light, sunshine and other environment adaptation And can realize passengers' contactless exit, and has carried out pilot Application.

In terms of stable and safe operation, it is a research work to ensure the safe and orderly operation of high-speed railway The most important thing. Comprehensive use of new technologies such as big data, artificial intelligence and satellite navigation A number of research and research work. First, we developed a high-speed railway operation safety big data platform, analyzed and dug The distribution law of high-speed railway operation faults in time and space has been excavated, and the high-speed railway operation faults have been strengthened Precise prevention and control of key equipment and people of the railway, and advance prevention of equipment failure Fan; Second, Beidou satellite navigation technology was used to build the foundation of Beijing Zhangjiakou high-speed railway Qianghe tunnel coverage enhancement system has realized the high-speed railway foundation of subgrade and slope High precision deformation monitoring of facilities and safety protection of operators; Third, we have developed video monitoring and wind, rain, snow and foreign matter monitoring for the whole Beijing Zhangjiakou high-speed railway line Platform, carried out comprehensive analysis and visual display of space-time big data Operational risks have been studied, judged and forewarned in advance; Fourthly, the EMU fault has been constructed Prediction and Health Management (PHM) platform to reveal the evolution and failure of EMU performance The rule of obstacle occurrence, guiding the development of EMU digital condition based maintenance; Fifth, development The intelligent integrated dispatching system of high-speed railway has been established to realize the daily scheduling plan of various types of work Preparation and centralized dispatching command; Sixth, we have developed passenger service and production management Control platform, improve the cooperation and linkage of high-speed railway station passenger transport organization integration business Ping. At the same time, the station lighting, air conditioning and other passenger transport equipment are effectively reduced Able to control.

"Intelligent innovation will be promoted in national railways." Ma Jianjun said, "By December 2021, the operating mileage of Chinese railways has reached 146000 km, including 38000 km of high-speed railway, ranking first in the world. through Through Beijing Zhangjiakou High speed Railway Science and Technology Winter Olympics Project, data platform and intelligent application have been developed And relevant algorithm models, which are generally applicable to other high-speed railway lines, It can be popularized in national railways. In fact, some system platforms have Promote and apply on other high-speed railway lines. stay In terms of intelligent ticketing, 12306 will be held in the Winter Olympics During this period, we provided international intelligent ticket buying services, and through the Winter Olympics demonstration It has promoted the transformation of 12306 into an international and comprehensive travel service website. Complete solution of railway 5G application on Beijing Zhangjiakou high-speed railway The successful application provides application demonstration and important reference for other high-speed railways. The passenger service and production management and control platform can The guidance screen and other passenger transport equipment are effectively controlled for energy conservation. Through the Winter Olympics demonstration Promote the development of high-speed railway stations in the direction of green energy conservation, and realize the national "double carbon ’ The goal is to contribute to the power of high-speed railway. ”(Liu Jia)
