The invention discloses a platform door gap detection system and a control method thereof.The platform door gap detection system comprises a DCU, an LCB, a safety circuit, a door state indicator lamp and a gap detection device.The DCU starts the gap detection device after detecting that a controlled sliding door is closed, and when the gap detection device detects that no foreign matter exists, a safety circuit relay contact of the gap detection device is kept closed, and the door state indicator lamp is switched on; a corresponding sliding door safety loop is closed; when a foreign matter exists, a gap detection device safety circuit relay contact is disconnected, a corresponding sliding door safety circuit is disconnected, a whole-side safety circuit is not connected, a DCU controls a door state indicator lamp of the corresponding sliding door to flicker, after the foreign matter is taken out, the whole-side safety circuit is closed, and the train can normally exit the station; when the gap detection device acts abnormally, after the corresponding sliding door is isolated through the LCB, the safety circuit on the whole side is closed, a train can normally go out, operation is simpler, meanwhile, when the device is abnormal, the device and the corresponding sliding door can be synchronously isolated, and safety is higher.
本发明公开了一种站台门间隙探测系统及其控制方法,包括DCU、LCB、安全回路、门状态指示灯、间隙探测装置,DCU检测到被控滑动门关闭后启动间隙探测装置,间隙探测装置检测到无异物时,间隙探测装置安全回路继电器触点保持闭合,对应滑动门安全回路闭合;有异物时,间隙探测装置安全回路继电器触点断开,对应滑动门安全回路断开,整侧安全回路不通,DCU控制对应滑动门的门状态指示灯闪烁,取出异物后,整侧安全回路闭合,列车可以正常出站;间隙探测装置动作异常时,通过LCB隔离相应滑动门后,整侧安全回路闭合,列车可以正常出,操作更为简单,同时装置异常时,可以将装置与对应的滑动门同步隔离,安全性更高。
