To provide an elevator door diagnosis device and a door diagnosis method capable of detecting an abnormality while recognizing which of a car door side and a landing door side is a cause of the abnormality when the abnormality occurs at an elevator door.SOLUTION: The elevator door diagnosis device comprises a door abnormality detection unit and a door diagnosis processing unit. The door abnormality detection unit detects an abnormality occurring during opening/closing of a car door of an elevator. The door diagnosis processing unit moves the car door to a position where it is not engaged with a landing door to open/close the car door again upon detection of the abnormality by the door abnormality detection unit when a car lands at one of floors to open/close the door. The abnormality is determined to be present at the floor where the car is landing when no abnormality is detected by the door abnormality detection unit at the time of opening/closing of the door, and the abnormality is determined to be present at the door when the abnormality is detected.SELECTED DRAWING: Figure 1

    【課題】エレベータドアで異常が発生した際に、異常の原因がかごドア側にあるか、乗場ドア側にあるかを認識しつつ異常を検出することが可能なエレベータのドア診断装置およびドア診断方法を提供する。【解決手段】実施形態によればドア診断装置は、ドア異常検出部とドア診断処理部とを備える。ドア異常検出部は、エレベータのかごドアが戸開閉した際に発生した異常を検出する。ドア診断処理部は、乗りかごがいずれかの階に着床して戸開閉した際にドア異常検出部で異常が検出されると、乗りかごを乗場ドアと係合しない位置に移動させてかごドアを再度戸開閉させ、当該戸開閉によりドア異常検出部で異常が検出されなかった場合には、着床していた階の乗場ドアに異常があると判定し、異常が検出された場合にはかごドアに異常があると判定する。【選択図】図1
