The invention relates to a rail transit vehicle passenger room lighting delay turn-off control circuit which is characterized in that two mutually redundant lighting turn-on train lines are arranged, a lighting turn-on instruction is sent out when the train lines are at high levels, a lighting turn-off instruction is sent out when the train lines are at low levels, lighting is turned on as long as one train line is at the high level, and when the two trains are at the low levels, the lighting turn-off instruction is sent out when the train lines are at the low levels. Therefore, the accuracy of illumination control is ensured. Meanwhile, the delay power supply bus is arranged between the permanent power supply bus and the lighting system power supply load, after the train is dormant, the delay power supply bus continues to supply power for a period of time, then a contact of the lighting delay power-off contactor is disconnected, connection between the lighting load and the permanent power supply bus is cut off, and the situation that the lighting load continuously consumes the capacity of a storage battery is avoided. The power shortage of the storage battery is prevented, the service life of the storage battery is effectively prolonged, and lighting on and lighting off in the train activation state and the train dormancy state can be achieved.

    本发明涉及一种轨道交通车辆客室照明延时关断控制电路,其通过设置两条互为冗余的照明开列车线,列车线高电平时,发出照明开指令,低电平时发出照明关指令,只要有一条列车线为高电平,照明即开启,当两条列车全部为低电平时,照明才关闭,保证了照明控制的准确性。同时,在永久供电母线和照明系统电源负载之间设置了一条延时供电母线,列车休眠后,延时供电母线会继续供电一段时间后照明延时断电接触器的触点断开,切断照明负载与永久供电母线的连接,避免照明负载持续消耗蓄电池容量,防止蓄电池亏电,有效延长蓄电池使用寿命,并且可实现列车激活和休眠两种状态下的照明开启和关闭。
