To provide an obstacle detection system capable of improving reliability and safety while suppressing increase in costs.SOLUTION: The obstacle detection system includes: a plurality of detection devices 211, 212, 213, 221, 222, 223 provided along a track 51 to detect the existence of an object on the track; transmission lines 40, 41, 42, 43 provided along the track and connected with the plurality of detection devices to transmit detection results of the plurality of detection devices; and ground radio devices 10, 11, 12 connected with one end of both ends of the transmission line to perform radio communication with a train 3 traveling on the track. The ground radio device includes: a detection result acquisition unit for acquiring detection results of the plurality of detection devices through the transmission lines; an obstacle determination unit for determining whether or not an object detected by the detection device is an obstacle by using the detection results; and a ground radio unit for transmitting obstacle determination information including information of specifying a position of the obstacle to the train when it is closer to the train than the ground radio device connected to the other end of both ends of the transmission line.SELECTED DRAWING: Figure 1

    【課題】コスト上昇を抑えながら信頼性・安全性をより向上させた障害物検知システムを提供する。【解決手段】軌道51に沿って設けられ、軌道上の物体の存在を検知する複数の検知装置211、212、213、221、222、223と、軌道に沿って設けられ、複数の検知装置が接続され複数の検知装置の検知結果を伝送する伝送線路40、41、42、43と、伝送線路の両端のうち一方の端に接続され、軌道上を走行する列車3と無線通信を行う地上無線装置10、11、12と、を備える。地上無線装置は、複数の検知装置の検知結果を、伝送線路を介して取得する検知結果取得部と、検知結果を用いて、検知装置で検知された物体が障害物であるか否かを判定する障害物判定部と、自身が伝送線路の両端のうち他の端に接続された地上無線装置よりも列車に近い場合に、物体の位置を特定する情報を含む障害物判定情報を列車に送信する地上無線部と、を備える。【選択図】図1
