To provide a door monitoring device which achieves a highly convenient control according to a door operating condition even if a signal from a door safety device mounted on an elevator is not available.SOLUTION: An elevator door monitoring device is connected to a maintenance worker terminal carried by a maintenance worker of an elevator via a communication line and monitors a door of the elevator. The elevator door monitoring device is provided with a current detector in an electric motor to open/close a car door and transmits information to urge the modification of the car door operation to the maintenance worker terminal when the number of times that the current detected by the current detector exceeds a threshold reaches a prescribed condition.SELECTED DRAWING: Figure 6
【課題】エレベーターに搭載されているドア安全装置からの信号が入手できない場合でも、ドアの動作状況に応じて利便性の高い制御を実現するドア監視装置を提供する。【解決手段】エレベーターの保守作業員が携帯する保守員端末と通信回線を介して接続され、前記エレベーターのドアを監視するエレベータードア監視装置において、かごドアを開閉する電動機に電流検出器を設け、前記電流検出器で検出した電流が閾値を超えた回数が所定条件となった場合、前記かごドアの動作を変更するよう促す情報を、前記保守員端末へ送信する。【選択図】図6
