As the "nerve" and "brain" of rail transit, the communication signal system is an important guarantee for the safe and efficient operation of rail transit, and is the concentrated embodiment of the high-end technical level. This morning, the 2019 China International Rail Transit and Equipment Manufacturing Industry Expo held the "Rail Transit Communication Signal Key Technology Forum". More than 10 rail groups from Changsha, Tianjin, Taiyuan, Xi'an and other places, as well as exhibitors and university guests gathered together to discuss the development of key technologies for rail transit communication signals in the era of big data, cloud computing and artificial intelligence.
Concept: fully automatic operation system to solve seamless transfer
In the road network coordination, how to reduce the transfer time of passengers and how to carry out intelligent control?
A fully automatic operation system is one solution. At the forum, Cui Ke, chief engineer of the Research and Design Institute of Casco signal Co., Ltd., introduced the fully automatic operation 2.0 system for smart subway that they are studying.
Cui Ke said that the system takes serving passenger behavior as the core and faces the multiple needs of intelligent subway. On the basis of the existing fully automatic operation system, it covers five parts: driverless train, intelligent dispatching, intelligent depot, intelligent station and intelligent operation and maintenance. It has greatly improved the intelligent level of center, station, depot, dispatching and operation and maintenance management, and realized the intelligent control of urban rail transit in the whole process and in the whole scope.
"China is currently one of the countries with the largest number of fully automatic operation projects in the world. Fully automatic operation has shown a blowout development in recent years, and China's rail transit has made great contributions." Trico said.
Situation: Rail Transit Helps Orderly Growth of Urban Agglomerations
On September 25 this year, when General Secretary Xi Jinping inspected the development of Beijing's rail transit construction and preparations for the operation of the Daxing Airport Line, he emphasized that urban rail transit is the development direction of modern big city transportation. The development of rail transit is an effective way to solve the disease of big cities, and it is also an effective way to build green cities and smart cities.
At the forum, Xie Yaozheng, deputy general manager and director of the R & D and Design Department of Tongzhi Rail Vehicle Co., Ltd., said that building a scientific and reasonable comprehensive transportation system and improving the level and structure of rail transit will contribute to the orderly expansion of urban spatial structure and the orderly growth of urban clusters.
"The construction of a rail transit system with different levels and different systems as the main body, orderly speed and slow, and a combination of primary and secondary is an organic response to the different traffic needs of each circle, and is an important ability of rail transit to promote the development of urban agglomeration traffic." Xie Yaozheng pointed out.
China's first subway was opened on October 1, 1969. At that time, it was not used for commercial operation. In the following 30 years, major domestic cities have their own first subway lines. By the end of 2018, 32 cities in China had opened and operated 155 urban rail transit lines, with a total mileage of 5140km, ranking first in the world.
The future: the development of intelligent high-speed rail, improve railway capacity
By the end of 2018, China's high-speed rail mileage had reached 29000 kilometers, accounting for 70% of the global high-speed rail mileage. Although China's high-speed rail has developed to the world's leading ranks, but only rely on encrypted road network, will increase the overall cost of transport capacity. We need to study intelligent high-speed rail, through intelligent technology to improve transport capacity, to solve the transport demand.
Xing Yi, deputy general manager of Beijing National Communication and Signal Research and Design Institute Group Co., Ltd., pointed out that the intellectualization of high-speed rail technology is to realize intelligent railway through human wisdom after obtaining all kinds of information on the railway. He also proposed that intelligent railway is the wide application of cloud computing, Internet of things, big data, artificial intelligence new technologies. With new technology, through comprehensive perception and the interconnection of everything, realize the informatization, automation and intelligence of the railway, and create a new generation of transportation system that is safer, more reliable, cost-effective, warm and comfortable, convenient, fast, energy-saving and environmentally friendly.
