The present invention relates to an escalator malfunction preventing method which converts a signal, outputted by sensing a rotation state of a driving unit through a malfunction preventing device of an escalator, into a waveform signal and detects speeding and reverse-driving generated due to deterioration, damage, and malfunction by using a phase and a pulse width of the converted waveform signal, thereby stopping an operation.

    본 발명은 에스컬레이터의 오작동 방지 장치를 통해 구동부의 회전상태를 감지하여 출력된 신호를 파형신호를 변환하며, 변환된 파형신호의 위상과 펄스폭을 이용하여 노후, 파손 및 고장에 의해 발생하는 과속 및 역주행을 감지하여 작동을 정지시킬 수 있도록 하는 에스컬레이터 오작동 방지 방법에 관한 것이다.
