To provide an obstacle monitoring device which can reduce or remove an undetectable region where an occurrence of a train passage obstacle cannot be detected, while increases of installation costs or maintenance costs are suppressed.SOLUTION: An obstacle monitoring device 1 comprises an impedance measuring part 3 to measure an impedance of a track circuit 11, an obstacle detecting part 5 to detect an occurrence of an obstacle of a train passage in a section of the track circuit 11 based on a change of an impedance of the track circuit 11 and a reporting part 7 to report that a train passage is impossible in the section of the track circuit 11 when the obstacle of the train passage occurs.SELECTED DRAWING: Figure 1 【課題】設置コストや維持コストの増加を抑制しつつ、列車通行の障害の発生を検知できない検知不能領域を減少させ又はなくすことのできる障害監視装置を提供する。【解決手段】障害監視装置１は、軌道回路１１のインピーダンスを測定するインピーダンス測定部３と、軌道回路１１のインピーダンスの変化に基づいて軌道回路１１の区間に列車通行の障害が発生したことを検知する障害検知部５と、前記列車通行の障害の発生時に軌道回路１１の区間が列車通行不能であることを通報する通報部７と、を有する。【選択図】図１
