A Study on the Prospective Safety Analysis Procedure for Safety Control System

안전제어시스템의 사전 안전성 해석절차 연구

The train control system using radio is based on the radio communication between an on-board control system and a ground control system unlike other train control systems that rely on track circuit. To realize a new train control system based on a new principle, it is important to analyze safety in a systematic manner at an early stage, and identify important factors for the system. For this reason, we think a procedure that select hazards and identify their causes and allocate safety requirements to such hazards. This paper describes this procedure to realize system safety.
