초록

최근 임베디드 시스템 기술의 발전에 따라 열차제어시스템의 자동화가 촉진되고 있다. 이를 위한 하드웨어의 안전성 검증을 위한 연구는 활발히 진행되고 있으나, 소프트웨어의 안전성을 검증하기 위한 체계적인 노력은 거의 이루어지지 않고 있다. 이 논문에서는 열차제어 시스템 소프트웨어의 안전성을 자동으로 평가 할 수 있는 소프트웨어 도구를 제안한다. 이를 위하여 관련 국제표준을 분석하였으며, 기존의 사용 소프트웨어 테스팅 도구들을 조사하였다. 이로부터 국제표준에서 요구하는 주요 요건을 테스팅 할 수 있는 도구를 제안하였으며, 이 도구는 소프트웨어 전 개발주기에서 이용이 가능하다. 이 도구는 기존의 테스팅 도구들과는 달리 소프트웨어의 안전성을 검증할 수 있다는 점에서 그 의의가 크다.

Abstract

Recent advances in embedded system technology have brought more dependence on automating train control. While much efforts have been reported to improve electronic hardware's safety, not so much systematic approaches to evaluate software's safety, especially for the vital software running on board train controllers. In this paper, we propose a new software tool to evaluate software safety for the train controller. We have reviewed requirements in the international standards and surveyed available tools in the market. From that, we identified necessary tests to meet the standards and proposed a tool that can be used during the whole software life cycle. We show the functional architecture and internal components of the tool. Our tool is unique in that it is a comprehensive tool specifically designed for software safety evaluation while other tools are not.
