The present invention relates to a signal transmission device for train recognition, which is to safely drive a signal generation board even in situations where high voltage power lines for train driving and external high voltage noise can be introduced, and at the same time, to safely protect a power element of an output board even if the signal generation board malfunctions or there is no output. According to the present invention, the signal transmission device comprises an insulating transformer (103) (105), an R-C network (106), a comparator and filter (107), and a voltage divider (109). The present invention enables safe signal transmission and generation of a driving signal without separate non-isolated connection between the signal generation board and a transmission board by the configuration.

    본 발명은 열차 인식을 위한 신호송출장치에 있어 열차 구동용 고전압 전원선과 외부의 고전압 잡음이 유입될 수 있는 상황에서도 안전하게 신호생성보드를 구동하고, 동시에 신호생성보드가 오동작하거나 출력이 없는 경우에도 출력보드의 전력소자를 안전하게 보호하기 위한 장치에 대한 것으로, 절연 트랜스포머(103)(105), R-C네트워크(106), 비교기및필터(107), 분압기(109)를 포함하는 것을 특징으로 한다. 본 발명은 상기와 같은 구성에 의해 신호생성보드와 송출보드간 별도의 비절연 연결이 없이 안전한 신호전송과 구동신호 생성이 가능하게 한다.
