Abstract

The railway signalling system for safe train operation regulates the train speed to ensure the safety distance between consecutive trains by using wayside facilities such as track circuits and interlocking systems. In addition, this signalling system controls the trackside equipment such as a railway point along the train line. This ground-equipment-based train control systems require high CAPEX and OPEX. To deal with these problems, the train control system using the on-board controller has been recently proposed and its related technologies have been widely studied. The on-board-controller-based train control system is that the on-board controller can directly control the trackside equipment on the train line. In addition, if this system is used, the wayside facilities can be simplified, and as a result, the efficient and cost-effective train control system can be realized. To this end, we have developed the prototypes of the on-board controller and wayside object control units which control the point and crossing gate and performed the integrated operation simulation in a testbed. In this paper, before the field test of the on-board-controller-based train control system, we perform the preliminary field trial including the installation test, wireless access test, interface test with other on-board devices, and normal operation test.

열차의 안전 운행을 위한 철도신호시스템은 궤도회로, 연동장치 등의 지상 설비를 이용하여 열차의 안전거리를 확보하기 위해 열차의 속도와 거리를 제어한다. 또한 이러한 철도신호시스템은 열차의 진로에 따라 선로전환기 등의 선로변 설비들을 제어한다. 이러한 지상 중심의 열차제어시스템은 높은 유지보수 비용이 요구된다. 이에 대한 해결책으로, 최근 차상중심 열차제어시스템이 제안되었고, 관련 기술들의 개발이 활발히 이루어지고 있다. 이러한 차상중심 열차제어시스템은 차상에서 직접 열차 진로상의 선로변 설비들을 제어하는 기술이며, 이러한 시스템의 도입으로 선로변 시설물들이 간소화되어 효율적이고 경제적인 열차제어시스템의 구현이 가능하다. 이에 따라 차상제어장치와 선로전환기, 건널목차단기 등의 선로변 제어장치의 시제품을 개발하였고, 테스트 베드를 구축하여 열차운영 시나리오에 따른 통합 운영 시뮬레이션을 수행하였다. 본 논문에서는 차상중심 열차제어시스템의 현장 적합성 시험에 앞서 설치시험, 무선망 통신시험, 차상제어장치의 인터페이스 시험 및 정상 기능 시험을 포함한 예비현장시험 결과를 기술한다. 시험 결과는 시험 시나리오의 모든 항목을 만족하였으며, 이를 통해 개발한 차상중심 열차제어시스템의 유효성을 확인하였다.
