To diagnose a status of a machine prior to a maintenance inspection so as to prevent occurrence of a defect or failure of the machine and to prevent deterioration of service for users, by remotely controlling a set speed value of the door opening/closing without dispatching an operator to the site.SOLUTION: An elevator door abnormality diagnosis system is provided with: a remote control unit 21 which outputs a set speed value of door opening/closing of an elevator door 8 which is modified to a value different from that of the normal operation; a door opening/closing speed control unit (a door control unit 15) which inputs the modified set speed value of door opening/closing so as to control the opening/closing speed of the elevator door 8; a speed sensor 10 which measures the opening/closing speed of the elevator door 8; and an abnormality diagnosis unit (a door control unit 15) which determines whether there is an abnormality in the elevator door 8 by comparing the modified set speed value of door opening/closing and the speed value measured by the speed sensor 10.SELECTED DRAWING: Figure 2
【課題】現場に保守点検員が出向かなくてもエレベータのドアの戸開閉速度設定値を遠隔制御することで、保守点検前に事前に機器の状態を判断することを可能とし、機器不具合及び故障の発生を未然に防ぎ、利用者に対するサービス低下を防止する。【解決手段】エレベータドア8の戸開閉速度設定値を、通常運転時とは異なる値に変更した戸開閉速度設定値を出力する遠隔制御部21と、変更された戸開閉速度設定値を入力してエレベータドア8の戸開閉速度を制御する戸開閉速度制御部(ドア制御部15)と、エレベータドア8の戸開閉速度を計測する速度センサ10と、変更された戸開閉速度設定値と、速度センサ10の速度計測値とを比較することによってエレベータドア8の異常有無を判別する異常診断部(ドア制御部15)とを具備する。【選択図】図2
