The present invention relates to a safety multiplexing device for a platform screen door comprising: a door control unit (DCU) (120) corresponding to a platform screen door (111) in a one-to-one manner, and including a motor control unit to control opening and closing of the platform screen door (111), and a first cable port (121) to which a main cable (C1) is connected; a plurality of platform screen door sensors (141, 142) which are arranged on the screen wall (112), and detect whether a person or an object is present around the platform screen door (111); and a multiplexing control board (130) which is connected between the platform screen door sensors (141, 142) and the DCU (120) by cables (C2, C3, C4), includes a second cable port (137) to which a main cable (C2) connected to the first cable port (121) is connected, and a plurality of sensor cable ports (131, 132, 133) to be connected to the platform screen door sensors (141, 142) by sensor cables (C3, C4), and outputs a detection control signal to the DCU (120) through the main cable (C1) if a detection signal is received from at least one among the plurality of platform screen door sensors (141, 142). Accordingly, multiplexing of the platform screen door sensors can be realized while using the DCU without modifying the structure of the DCU to strengthen the safety of operation of the platform screen door.

    본 발명은 승강장안전문용 안전 다중화 장치에 관한 것으로, 승강장안전문(111)에 일대일로 대응되어서 구비되고, 승강장안전문(111)의 개폐를 제어하기 위한 모터제어부와, 메인 케이블(C1)이 접속되는 제1 케이블포트(121)가 구비되어 있는 DCU(Door Control Unit)(120)와, 상기 스크린 벽체(112)에 구비되고, 승강장안전문(111) 주변에 사람이나 물체가 있는지 여부를 감지하는 복수의 승강장안전문 센서(141,142)와, 승강장안전문 센서(141,142)와 DCU(120) 사이에서 케이블(C2,C3,C4)에 의해서 연결되고, 제1 케이블포트(121)와 접속된 메인 케이블(C2)이 접속되는 제2 케이블포트(137)가 구비되어 있고, 승강장안전문 센서(141,142)와 센서케이블(C3,C4)에 의해서 연결하기 위한 센서케이블 포트(131,132,133)가 복수로 구비되어 있으며, 복수의 승강장안전문 센서(141,142) 중에서 적어도 하나로부터 감지신호를 수신하는 경우에는 메인 케이블(C1)을 통해서 DCU(120)로 감지제어신호를 출력하는 다중화 제어보드(130)를 포함하여 구성되는 것을 특징으로 하고, 이에 의하면, DCU의 구조 변경 없이 그대로 이용하면서 승강장안전문 센서의 다중화를 구현할 수 있어서 승강장안전문의 동작의 안전성을 강화할 수 있는 이점이 있다.
