위상차(PDOA)를 이용한 이동체 위치 및 속도 검지

초록

This paper proposes a new Position detection method for train speed control using the PDOA(Phase Difference of Arriving). 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 WRS(Wayside Radio Set). The VRS transmits a wireless signal to the WRS, the controller calculate a straight line with the PDOA. Next step calculate an exact position using track DB. This paper includes the concept, configuration, analysis and results of this method.
