Abstract

본 발명은 고장 자동절체형 데이타전송장치에 관한 것으로, 2중계 구조에서 고장절체디바이스를 이용하여 구성되어 있으며, 이러한 구성의 데이타전송장치의 전체구성에서 어느 한 부분에서 이상이 발생하면 자동적으로 바로 이상이 있는 부분만을 다른 예비부분으로 절체하여 정상동작상태를 유지할 수 있어 상용계와 예비계의 복합적인 장애에도 정상동작할 수 있기 때문에, 철도신호시스템의 중앙사령실과 현장역 설비사이에서 데이타를 전송해주는 데이타전송장치의 고신뢰성 확보에 유용하도록 한것이다.The present invention relates to a failure automatic switching type data transmission apparatus, and is configured by using a failure switching device in a dual relay structure, and when an error occurs in any part of the overall configuration of the data transmission apparatus having such a configuration, the error is automatically immediately changed. It is possible to transfer the data between the central command room of the railroad signal system and the field station equipment because it can maintain the normal operation state by switching only this part to another spare part and can operate normally even in the complex obstacles of commercial and spare systems. It is useful for securing high reliability of data transmission device.
