Embodiment Construction

[0017] With the rapid development of urban rail transit, a train control system based on vehicle-to-train communication emerged as the times require. This system directly sends the information of the vehicle to the front and rear vehicles through the wireless communication between trains, so as to achieve the purpose of tracking the vehicle in front and effectively improve the The traditional communication-based train control system (Communication Based Train Control System, CBTC) has the disadvantages of time-consuming train-ground communication and numerous trackside equipment. At the same time, under the influence of special transportation phenomena such as tidal passenger flow, based on the train virtual marshalling of the vehicle-to-vehicle communication train control system, the number and type of train marshalling are dynamically adjusted, and flexible marshalling strategies are adopted for peaks and flat and low peaks, which can effectively Reduce the waste of resources...

Abstract

The embodiment of the invention provides a virtual marshalling train turnout resource management method and system based on train-train communication. The method comprises the steps that an exclusive request for applying for a target turnout exclusive lock is sent to an object controller OC; an exclusive permission returned by the OC based on the exclusive request is received, and the exclusive permission is sent to a following vehicle based on vehicle-to-vehicle communication; when the virtual marshalling train passes through the target turnout, a lock release command is sent to the OC, and the OC is indicated to release a resource exclusive lock of the target turnout; then the master control train in the virtual marshalling train represents the whole virtual marshalling train to apply for a target turnout exclusive lock, it is ensured that application conflicts caused by simultaneous application of multiple trains during turnout resource application are avoided; and when the whole virtual marshalling train passes through the target turnout, the exclusive lock of the target turnout is released. It can be guaranteed that the virtual marshalling train normally passes through the turnout, and then the running efficiency of the train is improved.

Description

technical field [0001] The present application relates to the technical field of rail transit, in particular to a method and system for managing turnout resources of a virtual marshalled train based on vehicle-to-vehicle communication. Background technique [0002] With the rapid development of urban rail transit, a train control system based on vehicle-to-train communication emerged as the times require. This system directly sends the information of the vehicle to the front and rear vehicles through the wireless communication between trains, so as to achieve the purpose of tracking the vehicle in front and effectively improve the The traditional communication-based train control system (Communication Based Train Control System, CBTC) has the disadvantages of time-consuming train-ground communication and numerous trackside equipment. At the same time, under the influence of special transportation phenomena such as tidal passenger flow, based on the train virtual marshalling ...
