What kind of development has China’s high-speed rail experienced?

Analysis of the development prospects of the high-speed rail industry: Smart high-speed rail embarks on a new journey

High-speed rail travel will be more convenient

On August 8, 2018, "Fuxinghao" It will achieve a speed of 350 kilometers per hour between Beijing and Tianjin. By 2020, driven by the specific timetable for the completion and opening of the Beijing-Xiongan intercity railway, "transportation power, railway first" is no longer a simple slogan, smart high-speed rail is becoming The vanguard of "railway first" marches forward bravely on the road of independent development.

China's high-speed rail is developing rapidly

In August 2008, China's first high-speed rail, 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 "High-speed Railway Industry Market Foresight and Investment Strategic Planning Analysis Report" released by the Qianzhan Industry Research Institute, from 2013 to 2017, the country's railways completed fixed asset investment of 3.9 trillion yuan, and added 29,400 kilometers of railway operating mileage, including high-speed railways. 15,700 kilometers, which is the period with the most concentrated and intensive railway investment in history. By the end of 2017, the country's railway operating mileage reached 127,000 kilometers, including 25,000 kilometers of high-speed rail, accounting for 66.3% of the world's total high-speed rail and nearly two-thirds of the world's total high-speed rail. It strives to expand the railway network to about 175,000 kilometers by 2025, including about 38,000 kilometers of high-speed rail.

China’s smart high-speed rail has taken a new step in independent development. For example, the Beijing-Zhangjiakou High-speed Railway, which started construction in 2016, is an important support project for the 2022 Beijing Winter Olympics. It has a design speed of 350 kilometers per hour and a total length of 174 kilometers. The Chongli Railway leads from Xiahuayuan North Station of the Beijing-Zhangjiakou High-speed Railway to Taizicheng Station. The main line is 53 kilometers long and 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 on high-speed railways to comprehensively and efficiently utilize resources to realize high-speed railway mobile equipment, fixed infrastructure and internal Comprehensive perception of information between external environments, ubiquitous interconnection, fusion processing, active learning and scientific decision-making realize an intelligent high-speed railway system with integrated management of the entire life cycle.

Analysis of China’s high-speed rail development prospects

In terms of intelligent construction, the railway department will use the integrated application of BIM (Building Information Modeling), CIM (Computer Integrated Manufacturing) and other technologies in bridge construction. On the road, the intelligent beam field management system is adopted to realize the research and development and application of intelligent core equipment (tensioning, grouting, static load testing, etc.), and to realize the quality control and traceability management of the whole process of manufacturing, transportation and erection; in tunnel engineering, we strive to achieve The "three modernization" goals of advance geological forecasting informatization, tunnel surrounding rock measurement and three-dimensional laser section scanning informatization, and tunnel excavation and lining construction auxiliary decision-making informatization use intelligent prefabrication of tunnel segments and prefabricated tunnel bases to achieve shield Institutional operation status monitoring and collaborative management. At the same time, we will continue to improve the design level and construction quality of high-speed rail to 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. We will take the lead in building a developed and complete modern railway network in 2035.

In terms of intelligent equipment, the railway department will develop intelligent EMUs with self-sensing working status, self-diagnosis of operating faults, and self-guided safety decision-making. It will adopt an innovative head design based on aerodynamic performance to realize Beidou Satellite navigation system application, improved steep slope starting performance and power battery system, comprehensive mastery of 350 kilometers per hour automatic driving technology, and further improvement of high-speed train vibration, noise and other indicators.

In terms of intelligent operations, the railway department will build China's big data center, make extensive use of big data technology, dynamically analyze and grasp changes in passenger flow, implement more accurate allocation of transportation resources, and improve the high-speed rail's "one map per day" The transportation organization model makes high-speed rail dispatching, command, and operation organization more flexible and efficient.

In terms of smart services, the railway department will promote the integration of high-speed rail networks and the Internet, launch passenger itinerary planning, comprehensive transportation information sharing and other services to meet the requirements of 350 kilometers per hour, large capacity, high reliability, Uninterrupted mobile communication enables the transformation of single voice communication services to multimedia services such as data and video, providing passengers with better network services; at the same time, it expands and improves online ticketing, meal ordering, shopping, hotel reservations and "high-speed rail+***" One-stop services such as "Car Enjoy" make travel more convenient, fast and warm for passengers.
