Rail transit signal system with multi-network integration

Abstract

The invention relates to a rail transit signal system with multi-network integration. The system comprises a trackside train control subsystem which simultaneously supports the mixed tracking operation of a national railway train based on CTCS and an urban rail transit train based on CBTC, a compatible vehicle-mounted subsystem which is used for realizing cross-line operation of a national railway network, an intercity railway network, a city railway network and an urban railway traffic network, a networked intelligent scheduling subsystem which is used for realizing intelligent scheduling management of rail transit networks and coordination of network operation plans across different rail transit networks, an interlocking subsystem which is in communication connection with and interacts with the trackside train control subsystem, the compatible vehicle-mounted subsystem and the networked intelligent scheduling subsystem, and a train-ground wireless communication subsystem which provides communication for national railway trains and urban rail trains at the same time. Compared with the prior art, the rail transit signal system has the advantages of interconnection, deep fusion and the like.

Description

technical field [0001] The invention relates to a rail traffic signal system, in particular to a rail traffic signal system with multi-network integration. Background technique [0002] At present, there are four typical rail transit networks in China, which are national railway network, intercity railway network, urban railway network and urban rail transit network. The national railway network connects important central cities, with a target speed of 250-350km / h, a line operating speed of 300km / h, and an average station distance of more than 50km; intercity rail transit is a public rail transit line within a regional urban agglomeration, with a target speed of 160km / h~200km / h, the line length is about 150km, and the average station distance is about 10km; the urban rail transit lines and operating characteristics are between intercity rail transit and urban rail transit, and the speed target value is 120km / h~160km / h, The line length is about 80km; the urban rail transit ...

AI Technical Summary

Problems solved by technology

The national railway network mostly adopts the CTCS train control system, which has a high average travel speed and can meet the requirement of a 5-minute operation interval; urban rail transit mostly adopts the CBTC train control system based on wireless communication, with a low average travel speed and can meet the requirement of a 2-minute operation interval ; while the operational requirements of the intercity railway network and urban railways are between national railways and urban rail transit. According to different investment subjects and operational needs, some lines adopt the national railway train control type, and some lines adopt the urban rail train control mode. The different train control systems are very different, so that the trains of the national railway system cannot run on the urban rail system, and the urban rail system trains cannot run on the national railway system.

As a result, the line networks form separate networks, which cannot realize the sharing of line resources and train resources, and also increases the time cost of passengers traveling
