신뢰성 확보를 위한 철도 신호제어용 프로토콜 검정기 개발

초록

In this paper, we develope a protocol verification tool that verifies the correctness of rail signal control protocol type 2 specified in LTS(Labeled Transition System) by using model checking method. This tool removes many errors and ambiguities of an informal method used in the past and saves down expenditures and times required in the protocol development. Therefore it is expected that there will be an increase in safety, reliability and efficiency in terms of the maintenance of the signaling system by using the developed verification tool.
