To not only detect the abnormality of a door of an elevator but also specify a cause of the occurrence of the abnormality with a simple structure.SOLUTION: A door abnormality detection device 10 includes a data acquisition unit 110 for acquiring a plurality of kinds of load data that are varied at the time of opening/closing a cage door 2 of an elevator 1, a data storage unit 120 for classifying and accumulating the load data acquired by the data acquisition unit 110, and an abnormality determination unit 130 for detecting the abnormality of the door by comparing the load data acquired at the time of opening/closing the nearest cage door with the load data accumulated in the data storage unit 120 at the time of opening/closing the door normally. The abnormality determination unit 130 specifies a cause of the occurrence of the door abnormality by combining and comparing the plurality of kinds of load data when the door abnormality is detected.SELECTED DRAWING: Figure 4

    【課題】簡便な構成でエレベーターのドア異常を検出するだけでなく、その発生原因をも特定する。【解決手段】ドア異常検出装置10は、エレベーター1のケージドア2の開閉時に変動する複数種類の負荷データを取得するデータ取得部110と、データ取得部110が取得した負荷データを分類して蓄積するデータ格納部120と、直近のケージドアの開閉時に取得した負荷データと正常なドア開閉時にデータ格納部120に蓄積された負荷データとを比較することによってドア異常を検出する異常判定部130とを備える。さらに異常判定部130は、ドア異常を検出した場合に、複数種類の負荷データを組み合わせて比較することにより、当該ドア異常の発生原因を特定する。【選択図】図4
