The invention discloses a subway train ATO door interface data recorder. The recorder comprises a central controller, a plurality of optocoupler isolation switches which are respectively connected with the central controller and each contactor in a subway train ATO control circuit, and transmit signals of the contactors to the central controller in real time, and a data recording module which is connected with the central controller and is used for recording the signal input time and state of each contactor. According to the subway train ATO door control interface data recorder, an original circuit structure of a train does not need to be changed, ATO door control signals can be monitored and recorded in real time, when a fault occurs, the cause of the fault can be accurately judged, and rapid maintenance by workers is facilitated.
本发明公开了一种地铁列车ATO车门接口数据记录仪,包括:中央控制器;若干光耦隔离开关,分别与中央控制器和地铁列车ATO控制电路中的各个接触器连接,将接触器的信号实时传输至中央控制器;数据记录模块,与中央控制器连接,记录各个接触器的信号输入时间和状态。本发明提供的地铁列车ATO车门控制接口数据记录仪,不需改变列车原有电路结构,可以实时监控并记录ATO车门控制信号,能够在故障发生时,准确判断故障发生原因,便于工作人员进行快速维修。
