To diagnose a diagnosis target object of an elevator without deteriorating workability.SOLUTION: An elevator diagnostic device for diagnosing a diagnosis target object of an elevator by non-contact vibration measurement, comprises: a radar for obtaining a measurement signal including a vibration component of the target object; a determination unit that determines a filtering setting for separating the vibration component for each distance and/or each azimuth with respect to the measurement signal obtained using the radar; a separation unit that separates the vibration component while shifting the determined filtering setting; an extraction unit that extracts the vibration component of the diagnosis target object by comparing a chronological change of the vibration component separated by the separation unit with operation information of the elevator acquired by an acquisition unit; and a diagnostic unit that diagnoses the diagnosis target object, based on the extracted vibration component.SELECTED DRAWING: Figure 2
【課題】作業性を悪化させることなく、昇降機の診断対象物を診断可能とする。【解決手段】昇降機の診断対象物を非接触式の振動計測によって診断する昇降機診断装置であり、物体の振動成分を含む計測信号を得るためのレーダーと、レーダーを用いて得られる計測信号に対して、振動成分を距離別及び/又は方位別に分離するためのフィルタリング設定を決定する決定部と、決定したフィルタリング設定をずらしながら振動成分を分離する分離部と、分離部が分離した振動成分の経時的な変化と取得部が取得した昇降機の運行情報とを比較することにより、診断対象物の振動成分を抽出する抽出部と、抽出した振動成分に基づいて診断対象物を診断する診断部と、を備える。【選択図】図2
