The present invention relates to an escalator malfunction preventing device, which outputs a waveform signal by detecting the rotation speed and a direction of a driving unit of an escalator, converts the outputted waveform signal into a pulse signal to detect an overspeed and a contraflow driving signal by damage or a defect using a phase, and stops an operation.

    본 발명은 에스컬레이터 오작동 방지장치에 관한 것으로서, 에스컬레이터의 구동부의 회전속도 및 방향을 감지하여 파형신호를 출력하며, 출력된 파형신호를 펄스신호로 변환하여 위상을 이용하여 파손 또는 고장 등에 의한 과속 및 역주행 신호를 검출하여 작동을 정지시킬 수 있는 에스컬레이터 오작동 방지장치에 관한 것이다.
