City regional railway signal system and control method thereof

Abstract

The invention discloses a city regional railway signal system and a control method thereof. The city regional railway signal system comprises a control center device, a plurality of station devices, a line side unit and a vehicle device; the control center device is used for obtaining the running information of every train and outputting the movement information of the trains to the station devices after processing; the station devices are used for outputting the train movement information output from the control center device and the route information established through the line side unit to the vehicle device after processing; the line side unit is used for detecting the train position information, establishing train routes according to the interlocking information, enabling the route information of the trains to be generated into the message information and outputting the message information to the vehicle device; the vehicle device is used for adjusting the running state of the trains according to the train route control information and the message information and feeding back the adjusted running state of the trains to the station devices. According to the city regional railway signal system and the control method thereof, the functions such as the interconnection and intercommunication of the line network interior, accurate stopping, shielding gate linkage and interval automatic running and automatic turn-back can be achieved based on an ETCS-1 (Europe Train Control System-1) platform.

Description

technical field [0001] The invention relates to the technical field of railway signals, in particular to a city-area railway signal system and a control method thereof. Background technique [0002] Urban railway, also known as urban rail transit, is an electrified passenger railway that is specially operated between adjacent cities and group urban areas. The operating speed is generally between 120 and 200km per hour, and the distance between stations is small. This kind of line usually enters the urban area directly. , is a new type of rail transit transportation mode between urban rail transit (subway, light rail) and intercity high-speed railway. Compared with the subway, it has a larger average station distance, a higher speed target value, a higher travel speed, and a traffic density. Moderate features. [0003] And my country's existing rail transit signal system is divided into two categories of national railway and urban rail transit. The national railway signal s...

Problems solved by technology

[0004] At the same time, the current mainstream urban rail transit signal system uses the automatic train control system CBTC (Communication Based Train Control) based on wireless communication. There is no application performance at a speed of 120km / h and above, and the system construction investment is large, there are many trackside equipment, and the post-maintenance workload is heavy
