The invention relates to the technical field of rail transit, and discloses a redundancy switching emergency braking relieving circuit and method for a double-end redundancy signal system, and the circuit comprises two emergency braking control circuits. Each of the two emergency braking control circuits comprises an emergency braking loop and an ATC; when emergency braking is triggered by signal redundancy switching/emergency braking is triggered by non-signal redundancy switching, the ATC drives an emergency braking relay EBCR to lose power, and an emergency braking loop is controlled to be disconnected; when non-signal redundancy switching triggers emergency braking and needs to be reset, after a train stops stably, the ATC drives an emergency braking relay EBCR to be powered on, it is confirmed that the emergency braking triggering condition disappears, and an emergency braking loop is controlled to be closed; when signal redundancy switching triggers emergency braking and needs to be reset, the standby ATC drives the emergency braking relay EBCR and the emergency braking reset relay EBRVKR to be powered on, and then the emergency braking loop can be controlled to be closed. According to the invention, the emergency braking can be automatically and seamlessly relieved during fault switching of the double-end redundant signal system, so that the operation efficiency and the safety are greatly improved.

    本发明涉及轨道交通技术领域,公开了双端冗余信号系统冗余切换紧急制动缓解电路及方法,包括:两个紧急制动控制电路;两个紧急制动控制电路均包括紧急制动环路和ATC;当信号冗余切换触发紧急制动/非信号冗余切换触发紧急制动时,ATC驱动紧急制动继电器EBCR失电,控制紧急制动环路断开;当非信号冗余切换触发紧急制动需复位时,则待列车停稳后,ATC驱动紧急制动继电器EBCR得电,确认紧急制动触发条件消失,控制紧急制动环路闭合;当信号冗余切换触发紧急制动需复位时,则备系ATC驱动紧急制动继电器EBCR及紧急制动复位继电器EBRVKR得电,即可控制紧急制动回路闭合。本发明在双端冗余信号系统故障切换时能自动、无缝缓解紧急制动极大提高了运营效率与安全性。
