PROBLEM TO BE SOLVED: To provide an elevator door opening/closing diagnosis system capable of detecting a symptom of door opening/closing abnormality.SOLUTION: An elevator door opening/closing diagnosis system comprises: a normal diagnosis part 22 for performing normal diagnosis for determining whether or not, door opening/closing abnormality occurs, by comparing a time required for opening/closing a door at a normal diagnosis torque which is lower than that in a normal operation time, in inspection time of a door of an elevator, with a reference value; a low torque diagnosis part 24 for, when it is determined that, the door opening/closing abnormality does not occur, by the normal diagnosis part 22, performing low torque diagnosis for comparing a time required for opening/closing the door at a torque lower than the normal diagnosis torque, with the reference value; and a diagnosis result storage part 26 for associating a result of the low torque diagnosis by the low torque diagnosis part, with the torque in the low torque diagnosis, and storing the same.SELECTED DRAWING: Figure 3

    【課題】本発明は、戸開閉異常の兆候を検出できるエレベーターの戸開閉診断システムを提供することを目的とする。【解決手段】本発明に係るエレベーターの戸開閉診断システムは、エレベーターのドアの点検時に、通常運転時よりも低い通常診断トルクでドアを開閉させるのに要する時間を基準値と比較することで戸開閉異常が発生しているか否かを判定する通常診断を行う通常診断部22と、通常診断部22により戸開閉異常が発生していないと判定された場合に、通常診断トルクよりも低いトルクでドアを開閉させるのに要する時間を基準値と比較する低トルク診断を行う低トルク診断部24と、低トルク診断部による低トルク診断の結果を当該低トルク診断におけるトルクと関連付けて記憶する診断結果記憶部26と、を備える。【選択図】図3
