POSITION TRACKING AND OPERATING MANAGEMENT SYSTEM OF MOVING OBJECT BY USING PHASE DIFFERENCE

摘要

PURPOSE: A position tracking and operating management system of a moving object by using the phase difference is provided to seize the current position of the vehicle by using the phase difference between a wayside radio set(WRS) and a vehicle radio set(VRS) mounted on the moving object. CONSTITUTION: A position tracking and operating management system of a moving object by using the phase difference includes a vehicle radio set(VRS)(2,3), a wayside radio set(WRS)(4), a central radio set and a position tracking set. The VRS(2,3) are installed on the moving object to transmit the specific radio signal. The WRS(4) is installed along the lane at a predetermined interval to receive the radio signal from the VRS(2,3). The central radio set collects the radio signal from the WRS(4) and the identification information of the corresponding VRS. The position tracking set searches the previously stored traffic lane data base by receiving the identification information of the WRS(4) and the radio signal of the moving object. And, the position tracking set calculates the position information of the corresponding moving object by using the phase difference between the WRS(4) for the moving object from the radio signal of the moving object and the identification information of the WRS(4).
