The invention relates to a rail transit emergency lighting control circuit which comprises an emergency lighting control train line penetrating through a whole vehicle, a time delay module located on a head vehicle and a head vehicle contactor controlled by the time delay module, and the end of the emergency lighting control train line is connected with an emergency power supply of the head vehicle through a first normally open contact of the head vehicle contactor. A second normally open contact of the head car contactor is connected in series with a power supply loop of the head car emergency lighting lamp; the middle train is provided with a middle train contactor connected to an emergency lighting control train line, and a normally open contact of the middle train contactor is connected into a power supply loop of a middle train emergency lighting lamp in series. Every two adjacent vehicles are grouped, and the emergency lighting lamps are connected through the emergency lighting redundant train lines. A pairwise redundant power supply mode is adopted for vehicle emergency lighting power supply, the function of emergency lighting time delay after the whole train is dormant is achieved through an adjustable time delay relay, and the function of short circuit and overload isolation of a downstream control circuit is achieved by additionally arranging a circuit breaker.

    本发明涉及轨道交通紧急照明控制电路,包括贯穿整车的紧急照明控制列车线、位于头车延时模块、受控于该延时模块的头车接触器,紧急照明控制列车线的端部经头车接触器的第一常开触点连接头车的紧急供电电源,头车接触器的第二常开触点串联接入头车紧急照明灯具的供电回路;中间车设置有接在紧急照明控制列车线上的中间车接触器,中间车接触器的常开触点串联接入中间车紧急照明灯具的供电回路;相邻车辆两两分组,其紧急照明灯具之间通过紧急照明冗余列车线连接。本发明车辆紧急照明供电采用两两冗余的供电方式,整列车通过可调延时继电器实现整车休眠后紧急照明延时的功能,通过增加断路器实现下游控制电路短路和过载的隔离功能。
