초록

고속철도 차량기지에는 고전압임펄스(HVITC)와 AF 궤도회로를 사용하고 있다. HVITC는 열차의 위치검지 및 궤도 절손검지 기능을 하고, AF궤도회로는 열차제어 정보를 전송하여 고속열차의 이상 유무를 검지하는 출발 전 시험에 사용한다. 두 궤도회로는 별도로 구성되어 있고, 같은 레일을 사용하여 제어신호를 스위칭에 의해서 전송하고 있다. AF 궤도회로는 루프케이블을 궤도 안쪽에 설치하는 방법으로 구성할 수 있다. 그러면 스위치를 제거할 수 있고, 상시 시험용 제어신호를 전송할 수 있다. 이 경우에 두 궤도회로는 상호간섭이 발생할 수 있다. 본 논문에서는 두 궤도회로를 동시에 동작하는 경우에 발생되는 간섭을 두 회로의 모델링을 통하여 규명하였다.

Two types of track circuits are used in high speed railway car depots: one is High Voltage Impulse Track Circuit(HVITC); the other is AF track circuit. HVITC detects train occupation of blocks and broken rail; the AF track circuit is used for train onboard control system pretesting before departure. This testing is used to transmit train control information through the AF track circuit. The two systems are switched in turns for testing. We propose a system in which the AF track circuit is replaced by a loop cable that is installed on the inside rail; as such, engineers do not need to switch the systems. In cases in which the two systems run simultaneously, mutual interference may occur. In this paper, we identified this mutual interference by modeling of the two circuits.
