Abstract

Track circuit is a simple electrical device which lies in the connection of the two rails by the wheels and axle of locomotives and rolling stock to short out an electrical circuit, used to detect the absence of a train on rail tracks. In railway signaling system, there are similar systems such as RFID and wheel sensor, GPS etc, are research and developing. Hybrid track circuit is using RFID antenna and reader on the cab and RFID tag on the sleeper. because of the safety in railway operation, tag detection of train position detection function in the hybrid track circuit needs high reliability. This paper studied tag recognition enhancement used tag angles.

철도신호시스템에서 열차위치 검지기능은 선로의 레일을 전기회로의 일부분으로 사용하여 차륜에 의해 단락되어 열차의 유무를 검지하는 궤도회로, RFID와 차륜센서, GPS 등과 같은 여러 가지 방식으로 구현 연구가 되고 있다. 하이브리드 궤도회로는 안테나와 리더기를 차량에 설치하고, 태그를 침목위에 설치하여, 안테나에서 태그에 저장된 절대위치정보를 제어장치에 전송하여 열차위치를 인식하는 RFID 방식의 궤도회로이다. 열차위치검지기능에서 태그의 인식율은 열차운행의 안전에 직접적인 영향을 주게 되므로 고신뢰도를 요구한다. 본 논문에서는 방향각을 갖는 태그를 이용한 태그인식율의 향상에 관한 연구를 하였다.
