城市轨道交通区域控制器内通信列车联合筛选方法研究

Research on Joint Screening Method for Communication Trains in Urban Rail Transit Zone Controller

在城市轨道交通中,为实现列车的紧密追踪,CBTC系统需要识别两列通信列车之间没有非通信车。本文提出一种区域控制器内通信列车联合筛选方法。该方法通过ZC(区域控制器)综合两相邻通信列车位置信息并消除通信列车信息异步的影响,在确保安全的前提下完成通信列车间列车筛选,从而提高CBTC系统的运行效率。该方法具有通用性,可适用于两通信列车头对头、头对尾、尾对尾的中间筛选场景。

In urban rail transit,in order to achieve close tracking of trains,the CBTC system needs to identify that there are no non-communication cars between two communication trains.In this paper,a joint screening method for communication trains in the zone controller is proposed.In this method,the ZC(zone controller)synthesizes the position information of two adjacent communication trains and eliminates the influence of asynchronous communication train information,and completes the inter-communication train screening under the premise of ensuring safety,so as to improve the operation efficiency of the CBTC system.This method is universal and can be applied to the head-to-head,head-to-tail,and tail-to-tail intermediate screening scenarios of two communication trains.
