屏蔽门系统安全回路快速诊断方法

A quick diagnostic method to Safety loop of the Platform sliding door control system

安全回路作为屏蔽门控制系统的核心组成部分,直接影响屏蔽门系统运行的稳定性、安全性。屏蔽门系统通过安全继电器把安全回路已接通信号传送给信号系统,信号系统判断屏蔽门系统处于安全状态,地铁列车可以安全进站或发车。门机控制器将安全回路的状态以及门机的信息上传至主监控中心。可以对各屏蔽门的安全回路进行实时监控,一旦安全回路发生故障,可以迅速定位到故障点,并且进行及时维修,确保地铁运营的安全。

Safetyloop as thepart of the Platform sliding doorcontrol system,a direct impact on the stabilityand thesecurityof Platform sliding door system.The safetyloop of Platform sliding dooris switched on thesignaltransmitted to thesignalsystem through thesafety relay,signalsystem judges thePlatform sliding door systemin a safe state, the subway traincan safelystop orstart.The doorcontroller unit willsend the safety loop stateand the information of doorcontroller unittothe main monitoring system.the main monitoring system canmonitor the safety loopof eachPlatform sliding door,once thesafety circuitis in fault ,the monitor system can quicklylocatethe fault point,andtimelyrepair,ensurethe safety of subway operation.
