A multi-train control system and method based on train-vehicle communication

Abstract

The invention proposes a multi-train control system and method based on vehicle-to-vehicle communication. Including: S1. Judging the train departure status. If the train is controlled to depart, enter S2. If the train is controlled to receive the train, enter S3; Planned driving; S3, multiple trains enter the station in marshalling mode, dispatching equipment prepares the train receiving plan, and group control equipment controls the trains to enter the station and stop according to the plan. It breaks the mode of train independent control, group control multiple trains according to one train control mode, realize multi-train control and maximize Shorten the train tracking interval and shorten the departure time, so as to realize the high speed of the train, increase the density of receiving and departing trains at the station, maximize the excavation of the line transportation capacity, and improve the line transportation efficiency.

Description

technical field [0001] The invention belongs to the technical field of rail traffic control, in particular to a multi-train control system and method based on vehicle-to-vehicle communication. Background technique [0002] Currently, CTCS-2, CTCS-3, ETCS-1, ETCS-2, CBTC, FAO and other train control systems regard the train as an independent individual for train control. Under independent control, It is required that there must be a sufficient safety tracking interval between the trains. When the distance between the two trains is relatively close, according to the independent train control mode, it is necessary to reduce the speed of the rear vehicle and increase the distance from the front vehicle to provide safety for the braking of the rear vehicle. distance, thereby reducing the efficiency of train tracking. [0003] The current high-speed train control system and the urban rail traffic control train control system control the train as an independent individual, and thr...

Problems solved by technology

[0003] The current high-speed train control system and the urban rail traffic control train control system control the train as an independent individual, and through the blocking technology, the train is controlled according to the braking curve model of one braking. The high-speed train based on the quasi-moving blocking technology Both the control system and the urban rail transit train control system based on moving block technology cannot realize the group control capability, and both need to control the train operation under a certain safe braking distance between the trains. The vehicle control technology under the safe distance has already The bottleneck of the above two systems is reached
