Abstract

The inspection of distance to go train control system conducted only when train is in main line or inspecting line, that affects low work efficiency and hazard elements to safe operation. Before or after train operation, the interface test between on-board and wayside signal system must be conducted. In this paper, onboard signal interface inspection system based on the real-time automatic analysis of onboard system status information that is transmitted to the wayside system and the operation status check of the onboard signal device operates as a virtual train information that is transmitted to the onboard system have been proposed. And after building the inspection system to the inspecting track of Daejeon Subway Line 1, Panam Depot, the verification algorithm of proposed interface test and the results was presented. therefore, it has enhanced work efficiency to do not carry train operation of a half hour in test line to test on-board system.

차내 연산 열차제어시스템은 검수고에 지상신호장치가 설치되지 않은 경우 본선 및 시험선으로 출고하였을 때에만 점검이 가능하여 업무의 효율성 저하 및 안전운행에 위해요인으로 작용한다. 열차의 운행 전 또는 운행 후 안전운행 확보를 위한 측면에서 차상 지상신호 설비 간 인터페이스 동작시험이 반드시 필요하다. 본 논문에서는 지상에서 차상시스템으로 전송되는 가상의 열차 운행정보에 따른 열차 차상신호 장치의 동작상태 확인과 차상에서 지상시스템으로 전송되는 열차 상태정보에 대한 실시간 자동 분석을 기반으로 한 열차 차상신호 인터페이스 검사시스템을 제안하여 대전도시철도 판암기지에 구축, 차상 지상신호 간 인터페이스시험 알고리즘을 검증하였다. 이에 따라 차상 열차제어시스템 점검을 위해 약 30분간의 시험선 운행이 불필요하여 업무의 효율성을 크게 향상시켰다.
