The invention discloses a train platform compensator control method and device. A motor drives a movable pedal to move through a motor reduction gearbox, and the motor is controlled through a motor drive circuit; when the movable pedal stretches out or retracts back, the three phases of the motor are conducted with the three phases of the motor driving circuit; when the movable pedal is in a locked state, the three phases of the motor and the three phases of the motor drive circuit are disconnected, and the three phases of the motor are connected. The wiring condition of the motor can be changed through the relay, the motor isswitchedto a generator, the motor is driven by counter electromotive force current generated by rotation of the motor to move in the opposite direction, so that movement of the movable pedal is hindered, the motor reduction gearbox can play a role in changing the transmission torque, the torque borne by the movable pedal in the locked state is small, the resistance of the movable pedal is improved, and the load of the motor is reduced.
本发明公开了一种列车站台补偿器控制方法及装置:电机通过电机减速箱驱动活动踏板运动,所述电机通过电机驱动电路控制;当活动踏板伸出或缩入时,所述电机的三相均导通于电机驱动电路的三相;当活动踏板处于锁停状态时,所述电机的三相与电机驱动电路的三相均断开,且电机的三相之间导通。本发明可通过继电器改变电动机的接线情况,使其切换成发电机,利用电机转动产生的反电动势电流驱动电机往反方向运动,从而阻碍活动踏板的运动,本发明的电机减速箱能够起到改变传递扭矩的作用,使活动踏板在锁定状态下受到的扭矩较小,提升活动踏板的阻力,降低电机的负载。
