High-speed rail travel will be more convenient
August 8, 2018, the "Fuxing number" will be in the Beijing-Tianjin intercity to achieve the speed of 350 kilometers per hour operation, and by 2020, in the Beijing-Hsiungary Intercity Railway is completed and open to traffic of the specific timetable for the promotion of the "transportation power, railway first" is no longer just a slogan, but also a "railway first". Under the impetus of the specific schedule for the completion of Beijing-Hungary Intercity Railway in 2020, the slogan of "Transportation Power, Railway First" is no longer just a slogan, and the intelligent high-speed railway is becoming the front-runner of "Railway First", and marching forward on the road of independent development.
China's rapid development of high-speed rail
August 2008, China's first high-speed rail - Beijing-Tianjin Intercity High Speed Railway opened for operation, marking the arrival of China's high-speed rail era. According to the data of "Analysis Report on Market Prospecting and Investment Strategy Planning of High-speed Railway Industry" released by Prospect Industry Research Institute, from 2013 to 2017, the national railroad completed fixed asset investment of 3.9 trillion yuan, with a new railroad operating mileage of 29,400 kilometers, including 15,700 kilometers of high-speed railroads, which is the most concentrated and intense period of railroad investment in history. By the end of 2017, the operating mileage of national railroads reached 127,000 kilometers, including 25,000 kilometers of high-speed railways, accounting for 66.3% of the world's total high-speed railways and nearly two-thirds of the world's total high-speed railways. It strives to reach about 175,000 kilometers of railroad network by 2025, including about 38,000 kilometers of high-speed rail.
China's intelligent high-speed railroads have taken new steps toward independent development. For example, the Beijing-Zhangzhou high-speed railway, which started construction in 2016, is an important safeguard project for the 2022 Beijing Winter Olympics, with a design speed of 350 kilometers per hour and a main line length of 174 kilometers. Chongli Railway leads from Beijing-Zhangzhou high-speed railroad Xiayuan North Station to Taizicheng Station, with a mainline 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, Beidou navigation and other new technologies will be widely applied on high-speed railways, and resources will be comprehensively and efficiently utilized to realize comprehensive perception, ubiquitous interconnection, fusion processing, active learning and scientific decision-making of high-speed railways in terms of mobile equipments, fixed infrastructures and information between internal and external environments, and to realize the intelligent high-speed railroads system with integrated management of the whole life cycle.
Analysis of China's High-speed Railway Development Prospects
In terms of intelligent construction, the railroad department will adopt intelligent girder management system in bridge construction through the integration and application of BIM (Building Information Modeling), CIM (Computer Integrated Manufacturing) and other technologies, realize the research, development and application of intelligent core equipments (tensioning, pressurization, static load test, etc.), and realize the quality control and traceability management of the whole process of making, transporting and erecting; and realize the quality control and traceability management of the whole process of making, transporting and erecting; and realize the quality control and traceability management of the entire life cycle of the high-speed railway system. In tunnel construction, the company adopts intelligent girder management system, realizes the development and application of intelligent core equipment (tensioning and compression slurry, static load test, etc.), and realizes the whole process of quality control and retrospective management of production, transportation and erection; in tunnel construction, the company strives to realize the "triple" goals of over-advanced geological forecasting informationization, tunnel rock measurement and three-dimensional laser section scanning informationization, and auxiliary decision-making informationization of tunnel excavation and lining construction, adopts the intelligent prefabrication of tunnel tubular pieces and the assembly type tunnel base, and realizes the operational monitoring and collaborative management of shield tunnel machine. At the same time, the design level of the high-speed railway is continuously upgraded. Meanwhile, the design level and construction quality of high-speed railways will be continuously improved to ensure that the operating mileage of high-speed railways will reach more than 30,000 kilometers in 2020, about 38,000 kilometers in 2025, and take the lead in building a well-developed and perfect modern railroad network in 2035.
In terms of intelligent equipment, the railroad department will research and develop intelligent rolling stock with self-perception of working condition, self-diagnosis of operating faults and self-decision-making of guiding safety, adopt innovative design of head type based on aerodynamic performance, realize the application of the Beidou satellite navigation system, improve the performance of large gradient starting and the power battery system, comprehensively master the technology of 350km/hour auto-pilot, and further improve the indexes of vibration, noise, etc. of the high-speed train. vibration, noise and other indicators.
In terms of intelligent operation, the railroad department will build China's big data center, make extensive use of big data technology, dynamically analyze and grasp the changes in passenger flow, implement more accurate allocation of capacity resources, improve the transport organization mode of high-speed rail "one day, one map", so as to make high-speed rail dispatching and commanding, operation and organization more flexible and efficient.
In terms of intelligent service, the railroad department will promote the dual-network integration of high-speed rail network and the Internet, introduce services such as traveler's itinerary planning, comprehensive traffic information*** enjoyment, etc., and satisfy the speed of 350 kilometers per hour, high-capacity, high-reliability and uninterrupted mobile communication, realize the transformation of single voice communication service to multimedia services such as data and video, and provide travelers with better network service; at the same time, it will expand and improve the network services of ticket purchase, meal ordering, shopping, and other related services. At the same time, it expands and improves network ticketing, meal ordering, shopping, hotel booking and one-stop services such as "high-speed rail + **** enjoy the car", which makes travel more convenient, fast and cozy for travelers.
