Abstract

This paper presents the methods to acquire the Safety Certificate from Independent Safety Assessment based on the IEC or EN standard which is commonly applied to railway system for Automatic Train Protection (ATP) system in accordance with ERTMS/ETCS Level 1 system. This also shows approach methods and relative activities for project lifecycle to accomplish and ensure the system requirements of ATP system, RAMS and system quality activities. These kind of activities for quality assurance of ATP system to obtain Safety Certificate could improve the quality of domestic railway system based on On-Board system of ERTMS/ETCS Level 1 and also contribute to the growth of railway business.

본 논문에서는 철도신호시스템분야에서 중요한 신뢰성과 안전성 수준을 국제규격에 부합할 수 있도록 하기 위한 접근방법을 모색하며, 국철 구간의 차상신호시스템 (ERTMS/ETCS Level 1)도입에 따라 현실적이고 접근 가능한 구체적인 활동 사항들을 프로젝트 수행과 연관하여 기술한다. 이에 따라 시스템 전반에 걸친 RAMS 및 안전성 평가를 통한 인증활동에 대한 부분을 제시하며, 국내 철도 신호시스템 적용을 위한 차상신호 시스템(ERTMS/ETCS Level 1)에 있어 차상장치(On-Board)를 중심으로 품질 및 안전 무결성(SIL) 수준 확보에 따른 안전성 확보방안의 구체적인 위험도분석 및 평가 활동을 제시 하고자 한다
