It will be more convenient to travel by high-speed rail.
2065438+On August 8, 2008, Fuxing will run at a speed of 350 kilometers per hour between Beijing and Tianjin. By 2020, driven by the specific timetable for the completion and opening to traffic of Xiong Jing inter-city railway, "to become a transportation power, the railway goes first" is no longer just a slogan, and the intelligent high-speed railway is becoming the vanguard of "the railway goes first" and making bold progress on the road of independent development.
China's high-speed rail has developed rapidly.
In August, 2008, the first high-speed rail in China, the Beijing-Tianjin intercity high-speed rail, was put into operation, marking the arrival of the high-speed rail era in China. According to the data in the Analysis Report on Market Foresight and Investment Strategic Planning of High-speed Railway Industry released by Forward-looking Industry Research Institute, from 20 13 to 20 17, the fixed assets investment of national railways was 3.9 trillion yuan, and the new railway operating mileage was 29,400 kilometers, of which the high-speed railway15700 kilometers was the most concentrated and intensive railway investment in history. By the end of 20 17, the national railway mileage reached127,000 kilometers, including 25,000 kilometers of high-speed rail, accounting for 66.3% of the world's total high-speed rail, close to two-thirds of the world's total high-speed rail. Strive to reach175,000 kilometers by 2025, including 38,000 kilometers of high-speed rail.
China intelligent high-speed rail has taken a new step of independent development. For example, the Beijing-Zhangjia high-speed railway, which started on 20 16, is an important guarantee project for the 2022 Beijing Winter Olympics, with a design speed of 350 kilometers per hour and a total length of the main line of 174 kilometers. Chongli Railway leads from Xiahuayuan North Station of Beijing-Zhangjiakou High-speed Railway to Taizicheng Station, with a total length of 53 kilometers, which can initially realize intelligent construction, intelligent equipment and intelligent operation.
In the future, new technologies such as cloud computing, big data, Internet of Things, mobile Internet, artificial intelligence and Beidou navigation will be widely used in high-speed rail, and resources will be comprehensively and efficiently utilized to realize comprehensive perception, ubiquitous interconnection, integrated processing, active learning and scientific decision-making of information between high-speed rail mobile devices, fixed infrastructure and internal and external environment, and realize an intelligent high-speed rail system with integrated management throughout the life cycle.
Analysis on the development prospect of China's high-speed railway
In terms of intelligent construction, the railway department will adopt intelligent beam yard management system in bridge construction through the integrated application of BIM (Building Information Model), CIM (Computer Integrated Manufacturing) and other technologies to realize the research and development and application of intelligent core equipment (tensioning, grouting, static load test, etc.). ) to realize quality control and traceability management in the whole process of production, transportation and erection; In terms of tunnel engineering, efforts are made to realize the "three-oriented" goals of advanced geological prediction informatization, tunnel surrounding rock measurement and three-dimensional laser cross-section scanning informatization, and tunnel excavation and lining construction auxiliary decision informatization, and tunnel segments are intelligently prefabricated and assembled to realize the monitoring and collaborative management of shield machine operation state. At the same time, continuously improve the design level and construction quality of high-speed rail, ensure that the operating mileage of high-speed rail will reach more than 30,000 kilometers in 2020 and about 38,000 kilometers in 2025, and take the lead in building a developed modern railway network in 2035.
In terms of intelligent equipment, the railway department will develop intelligent EMUs with self-awareness of working conditions, self-diagnosis of running faults and self-decision of guiding safety, adopt innovative head design based on aerodynamic performance, realize the application of Beidou satellite navigation system, improve the starting performance of large ramps and power battery system, fully master the automatic driving technology of 350 kilometers per hour, and further improve the vibration and noise indicators of high-speed trains.
In terms of intelligent operation, the railway department will build China's big data center, widely use big data technology, dynamically analyze and grasp the changes of passenger flow, implement more accurate allocation of transportation resources, improve the "one map a day" transportation organization mode of high-speed rail, and make the high-speed rail dispatching command and operation organization more flexible and efficient.
In terms of intelligent services, the railway department will promote the integration of the high-speed rail network and the Internet, and launch services such as passenger itinerary planning and comprehensive traffic information sharing to meet the needs of 350 kilometers per hour, large capacity, high reliability and uninterrupted mobile communication, and realize the transformation from a single voice communication service to multimedia services such as data and video, so as to provide passengers with better network services; At the same time, we will expand and improve the through train services such as online ticket purchase, ordering, shopping, hotel reservation and "high-speed rail+* * * car enjoyment" to make passengers travel more convenient, fast and warm.
