A train collision avoidance method and system in a vehicle-to-vehicle communication state

Abstract

The train collision avoidance method and system under the vehicle-to-vehicle communication state provided by the embodiments of the present invention include: establishing a wireless communication connection with the preceding train adjacent to the same running track; receiving the first current speed transmitted by the preceding train and the first current acceleration information; according to the first current speed and the first current acceleration information, combined with the second current speed and the second current acceleration information of the following train, the following train is used as the following target to construct the following Model; according to the early warning information fed back by the car-following model, determine the operation and collision avoidance plan. The train collision avoidance method and system provided by the embodiments of the present invention realize the direct transmission of front and rear train information, reduce the dependence on the ground train control system, and improve the operating efficiency of the line; and according to the distance, speed and acceleration of the front and rear two cars Information is used to control train operation, thereby realizing collision avoidance between trains and improving the safety level of train operation.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of railway transportation, and in particular, to a train collision avoidance method and system in a vehicle-to-vehicle communication state. Background technique [0002] In the communication-based train control system (Communication Base Train Control, CBTC for short) of traditional urban rail transit, ground equipment is used to transmit and interact with all trains wirelessly. The train uploads its own running direction and position and other information to the ground zone controller (Zone Controller, ZC for short), and the ground ZC combines the information given by the interlocking subsystem to report to the jurisdiction based on the current position of the train, the condition of the line ahead and other factors. The train sends a move authorization. The train controls the operation of the train based on the operation plan of the valid movement authorization received in real time ...
