The invention provides a subway operation emergency system for preventing a train from colliding with a gate, and the system comprises an infrared correlation detector which comprises an infrared transmitter and an infrared receiver, the infrared transmitter is disposed at one side of a gate body, and the infrared receiver is disposed at the other side of the gate body; the annunciator is arranged beside the track, and the distance between the annunciator and the gate along the track line is larger than the braking distance of the train; the signal machine is connected with the infrared receiver and is also in communication connection with the train automatic control system; when the infrared receiver cannot receive the infrared signal of the infrared transmitter, the signal machine sends an early warning signal to the train automatic control system; and the automatic train control system comprises an emergency anti-collision module, and after the emergency anti-collision module receives the early warning signal sent by the signal machine, the train is controlled to be braked emergently through the automatic train control system. The train can be prevented from colliding with the gate in the closed or semi-closed state, and major safety accidents such as train derailment are avoided.
本发明提供一种预防列车撞击闸门的地铁运行应急系统,包括:红外对射探测器,包括红外发射器和红外接收器,红外发射器设于闸门门体的一侧,红外接收器设于闸门的门体的另一侧;信号机,设于轨道旁侧,沿轨道线与闸门的距离大于列车的制动距离;信号机与红外接收器相连接,还与列车自动控制系统通信连接;当红外接收器无法接收到红外发射器的红外信号时,信号机向列车自动控制系统发送预警信号;列车自动控制系统,包括应急防撞模块,应急防撞模块接收到信号机发送的预警信号后,通过列车自动控制系统控制列车紧急制动。本发明可以预防发生列车撞上关闭或半关闭状态的闸门,避免造成列车脱轨等重大安全事故。
