A Study on the Process to Establish Safety of Level Crossing

건널목장치에서의 안전성확보 방안 고찰

In this paper, the relationship between system engineering lifecycle and safety lifecycle is investigated. V diagram and IEC 61508 model are represented in the lifecycle model. V diagram easily shows the flow of information between phases. But it does not show the amount of work involved in each stage. IEC 61508 model describes the activities to be performed during each phase of the lifecycle. And also the causal-consequence analysis for the level crossing is presented Representing this analysis procedure, we are try to establish safety of level crossing.
