The invention discloses an emergency load power-on control circuit for a rail transit vehicle and a full-automatic driving train, and the circuit comprises a first contactor, and a main contact of the first contactor is connected between a power supply and an emergency load; one end of the first contactor auxiliary contact is connected with a first relay coil, and the other end is connected with the power supply; the first relay coil is connected with the power supply; a normally open contact and a normally closed contact of the first relay are connected in series and then are connected with the power supply; the positive end of a coil of the first contactor is connected between a normally open contact and a normally closed contact of the first relay; the positive end of a coil of the first contactor is connected with the power supply; the design thought of TCMS system logic judgment and hard wire switching execution is adopted, so that the redundancy and the controllability of the low-voltage power supply system can be improved; according to the invention, the problem of excessive capacity dissipation of the storage battery when the full-automatic driving train is dormant for a long time can be solved.

    本发明公开了一种轨道交通车辆及全自动驾驶列车紧急负载上电控制电路,包括第一接触器,所述第一接触器主触点连接在所述电源和紧急负载之间;所述第一接触器辅助触点一端接第一继电器线圈,另一端接所述电源;所述第一继电器线圈与所述电源连接;所述第一继电器的常开触点和常闭触点串联后接所述电源;所述第一接触器的线圈正端接入所述第一继电器的常开触点和常闭触点之间;所述第一接触器的线圈正端接所述电源采用TCMS系统逻辑判断加硬线切换执行的设计思路,可增加低压供电系统的冗余性和可控性;本发明可以解决全自动驾驶列车在长时间休眠时蓄电池容量耗散过多的问题。
