열차제어시스템 임베디드 소프트웨어 기능안전성 검증방안 연구

초록

The train control system is being converted to the computer system from the existing mechanical device, and the dependency on software is being increased rapidly. Though the size and degree of complexity of embedded software for train control system are slower than the development speed of hardware, it is expected that the size will be grown bigger gradually and the degree of complexity will be increased also. Accordingly, various software test and validation activities are highly recommended in the international standards related railway software. In this paper, we recommended a method functional black-box testing for train control system software.
