摘要
在采用CBTC系统的城市轨道交通线路上,当车-地无线通信设备或者地面ATP设备故障时,列车通常转为由后备系统控制行车.后备系统下列车追踪前车的方式决定了系统的运行能力,进一步决定了故障恢复时间以及对运行系统的影响严重程度和范围.该文通过一起故障分析了点式系统存在的不足,并分析了基于列车主动感知系统的追踪方案,说明基于主动感知的后备运行系统在高运行密度的线路上可具有更小的追踪间隔,并能减少列车下线,有效提高故障情况下的乘客服务水平.
Abstract
In urban rail transit lines using the CBTC system,when the train-ground wireless communication equipment or ground ATP equipment fails,the train usually turns to a backup operation system.The way for a train to tracking trains ahead in backup operation system determines the operating performance.It also determines the recovery time,which indicates the severity and scope of the impact on operation by the system failure.This article analyzes the shortcomings of the ITC system through a fault,and analyzes the tracking scheme based on the train active perception system,which shows that the backup operation system based on active perception can have a smaller headway on high density lines effectively,and can keep trains in service,and effectively improve the passenger service level under fault.
