초록

철도 지선 구간의 유지보수 비용을 최소화하기 위해 ICT 기반 차상제어시스템을 개발 중이다. 이 시스템은 기존의 열차제어방식과 달리 선로 주변 신호기와 고정폐색장치를 없애고 이동폐색방식을 적용하며 차상에서 선로전환기와 건널목을 제어하는 방식이다. 본 논문의 목적은 ICT 기반 차상제어시스템 개발 이전에 고려해야 할 주요 운영 이슈 사항을 분석하며 주요 대상은 열차운행준비, 운전 편의성, 관제역할, 폐색방식, 그리고 운영비용을 고려하였다. 열차 출발 전에 기관사가 DMI를 통해 입력하여야 할 입력데이터를 정의하였고 관련 업무 프로세스를 UML 도구를 활용하여 설계하였다. 기관사의 운전 편의성 측면에서는 역 진입 시의 제동시점 지원 필요성과 기관사의 원활한 운전 훈련을 위한 운전시뮬레이터가 필요하다. 기관사가 선로전환기와 건널목을 직접 제어하는 업무절차를 UML 도구로 설계하였다. 기존 운영 방식과의 차이를 확인하기 위해 고정폐색방식과 이동폐색방식 간에 비교 분석하였으며, 비용 측면에서는 기존방식과 ICT 방식의 신호설비에 따른 유지보수 비용 이점을 제시하였다.

In order to minimize the maintenance cost at local lines, Information & Communication Technology based onboard train control system is being developed. Unlike the central traffic control based fixed block system, this system use a moving block method and railway driver direct control switch and railway crossing. The purpose of this paper is to analyze the concerned main operational issues are as follows: the preparation of train operation, drivability, the role of driver and controller, block system and cost. We defined the role of driver and driver's input data for train service, and we designed the business process of driver using UML tool. We considered the aspect of drivability, DMI is needed to support the braking moment for the driver and driver training simulator. We designed the driver business process for control of switch and railway crossing. We analyzed the fixed block system and moving block system to confirm the difference with the existing operational method. The cost analysis structure is also needed for the operation cost comparison.
