The invention provides a shield door system safety circuit fault diagnosis circuit and a shield door system.In the shield door system safety circuit fault diagnosis circuit provided by the invention, a shield door system safety circuit fault diagnosis sub-circuit is arranged for each safety circuit relay in a shield door system safety circuit; the front-end wire harness state of the safety circuit relay is detected through the relay front-end wire harness detection unit, and the on-off state of the safety circuit relay is detected through the relay on-off state detection unit, so that the front-end wire harness state of a plurality of safety circuit relays and the on-off state of the safety circuit relays can be detected and monitored in real time; the specific reason of the safety circuit fault is that the front-end wire harness of the safety circuit relay is disconnected or the safety circuit relay is not closed can be found in time through the detection signal, and the specific position of the safety circuit fault can be positioned in time through the detection signal, so that the maintenance and troubleshooting time is greatly reduced; and the operation reliability of rail transit such as metros is improved.
本发明提供一种屏蔽门系统安全回路故障诊断电路及屏蔽门系统,在本发明提供的屏蔽门系统安全回路故障诊断电路中,针对屏蔽门系统安全回路中的每个安全回路继电器,分别设置有屏蔽门系统安全回路故障诊断子电路,通过继电器前端线束检测单元检测安全回路继电器的前端线束状态,通过继电器开闭状态检测单元检测安全回路继电器的开闭状态,能实时对多个安全回路继电器的前端线束状态及安全回路继电器的开闭状态进行检测监控,通过检测信号能及时发现安全回路故障的具体原因是安全回路继电器前端线束断开还是安全回路继电器没闭合,通过检测信号还能及时定位安全回路故障的具体位置,极大地减少了维修和排查时间,提高了地铁等轨道交通的运行可靠性。
