The invention discloses an elevator band-type brake circuit, a detection method and a computer storage medium, and relates to the technical field of power electronics. The elevator band-type brake circuit is characterized in that a control unit receives a band-type brake signal and controls a first field-effect tube, a first relay and a second relay to be sequentially switched off based on the band-type brake signal; the control unit detects whether the first field effect transistor completes the turn-off operation flow or not through action feedback of the brake, and/or detects whether the first relay and the second relay complete the turn-off operation flow or not through the detection circuit; and if not, the control unit generates an alarm signal. By means of the mode, the detection circuit is arranged, action feedback of the brake is received, the first field-effect tube, the first relay and the second relay are detected, the use safety of the circuit is improved, meanwhile, the turn-off sequence of the first field-effect tube, the first relay and the second relay is controlled in the brake contracting process, and the brake contracting safety is improved. And the service life of the relay is prolonged.

    本发明公开了一种电梯抱闸电路、检测方法以及计算机存储介质,涉及电力电子技术领域。该电梯抱闸电路包括:控制单元接收到抱闸信号,基于抱闸信号控制第一场效应管、第一继电器和第二继电器依次关断;控制单元通过制动器的动作反馈检测第一场效应管是否完成关断的操作流程,和/或通过检测电路检测第一继电器和第二继电器是否完成关断的操作流程;若否,则控制单元产生报警信号。通过上述方式,通过设置检测电路和接收制动器的动作反馈,对第一场效应管、第一继电器和第二继电器进行检测,提高了电路的使用安全性,同时通过在抱闸过程中对第一场效应管、第一继电器和第二继电器的关断顺序进行控制,提高了继电器的使用寿命。
