Abstract

This paper analyzes the hazard related to train control, the functional requirements for atrain control system(TCS) and the automatic train protection(ATP) functional allocation that ensures the interoperability of a radio communications-based TCS. In addition, the interoperability can be obtained using wireless communications technology standards and standardized functional allocations of TCS performed on the wayside and onboard. Using this information, an integrated operating system for a rail network can be constructed. The functional allocations of TCS that support interoperability, require hazard analysis of TCS and definition of the system requirements. The hazard factors for a TCS are confirmed through setting the train safety space control and train speed limit excess. Furthermore, this paper determines the impact of the hazard factors on the TCS and, defines the functional requirements for the TCS subsystems and the ATP wayside and onboard functional allocations.

연구는 무선통신기반 열차제어시스템의 상호운영성(interoperability)을 확보하기 위하여 열차제어와 관련된 위험원 분석, 열차제어시스템의 기능요구사항 설정 및 차상과 지상ATP(Automatic Train Protection)장치의 기능배치를 포함하고 있다. 개방형 무선통신기술을 활용하고, 지상과 차상에서 수행되는 열차제어시스템의 기능배치를 표준화화여 상호운영성을 확보할 수 있으며, 이를 통하여 철도망의 통합운영체계를 구축할 수 있다. 상호운영성을 지원하는 열차제어시스템의 기능을 지상과 차상에 배치하기 위해서는 위험원 분석과 시스템 요구사항 정의를 필요로 한다. 열차제어시스템의 위험원으로 열차안전간격제어와 열차제한속도초과를 설정하여 위험원 요인을 확인하였다. 또한 위험원 요인이 열차제어시스템에 미치는 영향을 확인하고 열차제어시스템의 하부장치의 기능요구사항과 ATP의 지상기능과 차상기능 배치를 정의하였다.
