통신기반 열차제어시스템 성능평가를 위한 로밍시뮬레이터 개발

초록

This paper assesses communication performance using a roaming simulator when roaming occurs between onboard and ground wireless communication devices for communication based train control system (CBTC). We developed a roaming simulator to check communication performance before installing ground and onboard equipments on actual wireless sections. The roaming simulator to be introduced in this paper is for roaming simulation before conducting CBTC field test, which is the project to develop Urban Rail Signaling System Standards, being conducted in KRRI. Therefore, if you use the roaming simulator before the field test,you can predict various roblems to occur in actual environment and reduce time, cost and people necessary to resolve these problems.
