To make it possible to detect a sign of abnormality in a platform fence accurately without being affected by an environmental factor.SOLUTION: A platform fence state monitoring device 1 acquires a first motor current waveform signal of a first motor 13a for driving a first door part 12a when the first door part 12a and a second door part 12b of a platform fence 10 installed on a platform are simultaneously controlled to be opened/closed and a second motor current waveform signal of a second motor 13b for driving the second door part 12b, and performs prescribed comparative determination processing based on the first motor current waveform signal and the second motor current waveform signal to detect a sign of abnormality relating to any of driving mechanisms of the first door part 12a and the second door part 12b.SELECTED DRAWING: Figure 1 【課題】環境要因に左右されることなく、ホーム柵の異常の兆候を精度よく検出できるようにすること。【解決手段】ホーム柵状態監視装置１は、プラットホームに設置されたホーム柵１０の第１の扉部１２ａ及び第２の扉部１２ｂが同時に開閉制御されているときの第１の扉部１２ａを駆動する第１のモータ１３ａの第１のモータ電流波形信号と第２の扉部１２ｂを駆動する第２のモータ１３ｂの第２のモータ電流波形信号とを取得し、第１のモータ電流波形信号と第２のモータ電流波形信号とに基づく所定の対比判定処理を行って第１の扉部１２ａ及び第２の扉部１２ｂの何れかの駆動機構に係る異常の兆候を検出する。【選択図】図１
