Method and device for automatically unlocking degraded vehicle path based on rear vehicle perception

Abstract

The embodiment of the invention provides a method and device for automatically unlocking a degraded vehicle path based on rear vehicle perception, and relates to the technical field of rail transit. The method comprises the following steps: acquiring a degraded train path of a communication fault train, wherein the communication fault train represents a train which cannot communicate with a train control system and other trains; acquiring train sensing information collected by a train-mounted intelligent eagle eye system ITE included in the train with normal communication; and based on the train sensing information and the degraded train path, determining an available track section, and performing unlocking processing on the available track section. Therefore, the degraded vehicle path does not need to be unlocked after the communication fault train completely runs out of the degraded vehicle path, but the available track section is determined in real time according to the train sensing information, and automatic unlocking processing is carried out, so that the utilization rate of road resources is improved, the operation influence on the normal communication train due to the fact that the section is occupied by the degraded train path is reduced, and the operation efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of rail transit, in particular, to a method and device for automatically unlocking a degraded vehicle path based on the perception of rear vehicles. Background technique [0002] At present, whether it is a traditional CBTC system (Communication Based Train Control System) or a train control system based on vehicle-to-vehicle communication, it must rely on communication between various devices to obtain line information or train information ahead. However, due to the dependence on communication, when the train communication equipment fails and the train is degraded, it will not only affect the operation of the train, but also affect other trains on the running line, which may lead to the degradation of other trains with normal communication equipment, thereby affecting operational efficiency. [0003] When a train has a communication failure and becomes a degraded vehicle, it often plans the degrad...

Problems solved by technology

[0004] However, on the one hand, this way of unlocking the path of degraded vehicles is too dependent on manual labor, and on the other hand, it will lead to the occupation of too many road resources, which will affect the operation of normal trains, thereby affecting operational efficiency.
