무선통신을 이용한 철도차량의 위치 및 속도 검지시스템 설계

초록

This paper proposed a new position detection method for train speed control using the PDOA(Phase Difference of Arrival). This method aims to apply to AGT(Automated Guide way Transit) systems, operated with driverless. So it is absolutely required to range, calculate and decide a train position precisely. This system consists of VRS(Vehicle Radio Set) and WRS(Wayside Radio Set). The VRS transmits a wireless signal to the WRS, the controller calulate a straigt line with the PDOA. Next step calculate an exact position using track DB. This paper incudes the concept, configuration, analysis and results of this method.
