Abstract

The communication-based train control (CBTC) technology is a kind of railway signaling technologies and is to control the train operation through communication. A project adopting the CBTC technology is in progress and its object is to develop interoperable and interchangeable subsystems. Thus the purpose of this paper is on how to develop the required subsystems and integrate them successfully without sufficient design information at the system level. Accordingly this project shall require the integration and test at the system level. In order to do so, a top-level system specification shall be needed, which is not available in the current phase of the project. The main objective of the test and evaluation activities is to see whether the developed system meets the system specification. In this paper, we describe how the test and evaluation can be carried out based on the subsystems design specifications, considering the system architecture and the operation concept of the existing system as well.

현재 추진되고 있는 무선통신을 기반으로 하는 열차제어시스템 개발 프로젝트에서는 상호운영성 및 상호교환성을 고려하는 하부시스템의 개발을 목표로 하고 있다. 이 프로젝트는 상위 시스템 수준의 설계보다는 주로 하부시스템의 설계에 집중되어 있다. 시스템에 대한 시험평가는 시스템 사양에 대한 만족 여부를 확인하는 것이며, 이에 따라 시스템 수준으로 통합된 시스템 사양서가 필요하다. 본 연구에서는 시스템 사양서가 마련되지 않은 하부시스템의 설계단계에서 최상위 시스템 수준의 시험평가에 대한 방안을 제시하였다.
