Abstract

The invention relates to the technical field of subway vehicle doors, and discloses a novel door restarting control circuit and method. The circuit comprises components such as a zero-speed relay, a cab activation relay, a restarting relay and the like, and the restarting contactor is controlled to be turned on or off by combining a restarting instruction through detecting a train zero-speed and cab activation signal and utilizing a power-losing delay characteristic, so that the power supply loop of the gate controller is closed again after being disconnected for a short time, and the one-key synchronous restarting of the whole car door is achieved. This design adaptation manual driving and unmanned mode ensure the synchronous action of full train door through restarting the door controller train line, effectively promote the emergent processing efficiency of door trouble, satisfy the intelligent demand of railcar.
