The newly-built Fuzhou-Xiamen railway is the first high-speed railway with a design speed of 350 kilometers per hour in Fujian Province and the first cross-sea high-speed railway in the country. A few days ago, the reporter learned from the Intelligent Fuzhou-Xiamen Railway Science and Technology Innovation Seminar that the Fourth Railway Institute has carried out 56 intelligent projects and 25 scientific research topics to introduce intelligent design into the Fuzhou-Xiamen Railway.
In the past 10 years, China's high-speed rail has developed rapidly, and a huge high-speed rail network of "four vertical and four horizontal" has been built, and the majestic blueprint of "eight vertical and eight horizontal" is also ready to emerge. Statistics show that up to now, China has opened 25000 kilometers of high-speed rail lines, accounting for 2/3 of the world's total high-speed rail. The concept of "transportation power, railway first" should not only take the lead in the scale of the road network, but also be reflected in the road of intelligent development. Under the unified deployment of China Railway Corporation, a series of construction technologies of intelligent railway are being tested first in cutting-edge projects such as Beijing Zhangjiakou high-speed railway and Fuzhou Xiamen high-speed railway. More convenient, fast and warm high-speed railway travel is getting closer and closer to us.
Intelligent high-speed rail refers to the use of cloud computing, Internet of Things, big data, artificial intelligence, mobile Internet, BIM and other advanced technologies to promote the development of railways from digital to intelligent and intelligent. The intelligent Fuxia design research being carried out by the Fourth Railway Institute covers three parts: "intelligent construction", "intelligent equipment" and "intelligent operation.
Intelligent construction, fine construction to ensure quality. Through the integration and application of BIM (Building Information Model), CIM (Computer Integrated Manufacturing) and other technologies, the fine construction of bridges, tunnels and other projects is realized to ensure the quality control and traceability management of the whole process from blueprint to completion. In the design of Quanzhou Bay Bridge on Fuzhou-Xiamen high-speed railway, the Fourth Railway Institute has already carried out research on "three-dimensional collaborative management system for bridge coordination construction" in advance, completed BIM modeling, and implemented operation status monitoring in the whole process of bridge construction, transportation and erection.
Intelligent equipment, improve efficiency and promote development. At present, my country has opened self-driving trains on two intercity railways with a speed of 200 kilometers per hour in Guanhui and Fozhao in the Pearl River Delta. China is working hard to fill the gap in the world's high-speed rail self-driving technology between 300 kilometers per hour and 350 kilometers per hour, and will use it on the first batch of intelligent high-speed railways in Fuxia and Jingzhang. At the same time, the Beidou satellite navigation system independently developed by China will be adopted to escort the safe and punctualized operation of high-speed rail.
Intelligent operation, details change to benefit the people's livelihood. After the Fuzhou-Xiamen high-speed railway is opened to traffic in the future, it will dynamically grasp the changes of passenger flow through big data, and realize a more flexible and efficient operation organization with a more accurate "one map per day" transportation organization mode. The self-service management of station ticketing, synchronous security check, station Wi-Fi station navigation system design, online ticket purchase, meal reservation, shopping, hotel reservation and "high-speed rail shared car" and other more humanized and scientific services not only make China's railway move towards a new stage of intelligent development, but also mean surprising benefits for passengers.
The Fuzhou-Xiamen high-speed railway has a total length of 277 kilometers and will start construction in September 2017 with a construction period of 5 years. In November 2017, the Fourth Railway Institute established the Fuzhou-Xiamen Railway "Excellent Engineering Intelligent High-speed Railway" research working group to carry out early research on bridges, geology, catenary, and surveying. The relevant design person in charge of the Fourth Railway Institute said that after the completion of the Fuzhou-Xiamen high-speed railway, it will be connected from Fuzhou to Xiamen within one hour. At the same time, the engineering quality, equipment, operation management, and service quality of this high-speed railway will reach first-class standards. The new attitude leads the new fashion of railway travel ".
