To provide a moving vehicle position detector with which it is possible to detect the position of a moving vehicle (e.g., a train) before start of movement.SOLUTION: A moving vehicle position detector includes a fixed wireless station 7 for performing wireless communication with an onboard wireless station (mobile wireless station) amounted in a train T and installed in a station or vehicle base (mobile facility) where a plurality of trains T (moving vehicle) can stand by, and is constituted so as to receive a radio wave transmitted from the onboard wireless station with the fixed wireless station 7 and calculate its arrival direction (radio wave arrival angle θ), as well as calculate the distance D from the fixed wireless station 7 to the train T (onboard wireless station) on the basis of a radio wave reciprocation time between the fixed wireless station 7 and the onboard wireless station and specify the position of the train T on the basis of the calculated radio wave arrival angle θ and distance D.SELECTED DRAWING: Figure 5
【課題】移動開始前の移動体(列車等)の位置を検知することのできる移動体位置検知装置を提供する。【解決手段】移動体位置検知装置は、複数の列車T(移動体)が待機可能な停車場又は車両基地(移動体施設)に設置されて列車Tに搭載された車上無線局(移動体無線局)との間で無線通信を行う固定無線局7を含み、前記車上無線局から送信された電波を固定無線局7で受信してその到来方向(電波到来角θ)を算出すると共に、固定無線局7と前記車上無線局との間の電波往復時間に基づき固定無線局7から列車T(の前記車上無線局)までの距離Dを算出し、算出された電波到来角θ及び距離Dに基づき列車Tの位置を特定するように構成されている。【選択図】図5
