PROBLEM TO BE SOLVED: To provide a door abnormality detection device of an elevator which can specify possible cause for opening/closing abnormality of a door.SOLUTION: In a door abnormality detection device of an elevator comprising door detection means for detecting abnormality which is generated when a door 1 is opened/closed, the door detection means includes: a three-axis acceleration sensor 8 which detects an acceleration of opening/closing operation of the door 1; acceleration abnormality detection means which detects abnormality of opening/closing operation of the door 1 based on a change in acceleration of opening/closing operation of the door 1 detected by the three-axis acceleration sensor 8; and specification means which specifies abnormal cause of opening/closing operation of the door 1 based on information obtained by the three-axis acceleration sensor 8 and the acceleration abnormality detection means.SELECTED DRAWING: Figure 3

    【課題】ドアの開閉異常の原因を特定することができる昇降機のドア異常検出装置の提供。【解決手段】本発明は、ドア1が開閉する際に発生する異常を検出するドア検出手段を備えた昇降機のドア異常検出装置において、前述のドア検出手段が、ドア1の開閉動作の加速度を検出する3軸加速度センサ8と、この3軸加速度センサ8によって検出されたドア1の開閉動作の加速度の変化に基づいて、ドア1の開閉動作の異常を検出する加速度異常検出手段と、3軸加速度センサ8及び加速度異常検出手段によって得られた情報に基づいて、ドア1の開閉動作の異常原因を特定する特定手段とを含んでいる。【選択図】図3
