Abstract

In this study, Urban maglev is applied to inductive-loop speed and position detection system for the top-level classification system for the entire system, and performed functional analysis On-board signal equipment, Wayside-signal equipment divided by the reliability, availability, maintainability, and safety through analysis of the proposed formula. RDB and by applying a system service for each device was calculated to availability, safety analysis. The PHA, FMEA, HAZOP over the Top Event of the FTA is performed by presenting the results. This also shows approach methods and relative activities for project to accomplish and ensure the system requirements.

도시형 자기부상열차 실용화사업에 적용된 유도무선루프방식 열차제어시스템에 대하여 최상위 레벨에서 전체 시스템에 대한 시스템 분류, 기능 분석을 시행하고 차상신호설비, 지상신호설비로 나누어 신뢰도, 가용도, 유지보수도 및 안전도를 수식을 통하여 분석한 결과를 제시하였다. RAM 분석은 신뢰도 블록도(RBD)를 각 장치별로 적용하여 시스템 서비스 가용도를 산출하였고, 안전도 분석은 PHA(예비위험원 분석), FMEA (고장모드영향분석), HAZOP을 통한 각각의 정상사상(Top Event)의 FTA(고장트리분석)을 시행하고 그 결과를 제시하여 RAMS 목표 값에 도달함을 수식을 통하여 증명하였다.
