The invention relates to an elevator diagnosis device and an elevator diagnosis method, which can diagnose a diagnosis object of an elevator without worsening operability. The elevator diagnostic device diagnoses an object to be diagnosed of an elevator by means of non-contact vibration measurement, and is provided with: a radar for obtaining a measurement signal including a vibration component of the object; a determination unit that determines filter settings for separating vibration components by different distances and/or different orientations with respect to a measurement signal obtained using the radar; a separation unit that separates the vibration component while shifting the determined filter setting; an extraction unit that extracts the vibration component of the object to be diagnosed by comparing the change over time of the vibration component separated by the separation unit with the operation information of the elevator acquired by the acquisition unit; and a diagnosis unit that diagnoses the object to be diagnosed on the basis of the extracted vibration component.

    本发明涉及升降机诊断装置以及升降机诊断方法,能够在不使作业性恶化的情况下诊断升降机的诊断对象物。升降机诊断装置通过非接触式的振动测量来诊断升降机的诊断对象物,具有:雷达,其用于得到包含物体的振动成分的测量信号;决定部,其针对使用雷达得到的测量信号,决定用于将振动成分按不同距离和/或不同方位进行分离的滤波设定;分离部,其一边错开决定出的滤波设定一边分离振动成分;提取部,其通过对分离部分离出的振动成分的经时性的变化与取得部所取得的升降机的运行信息进行比较,提取诊断对象物的振动成分;诊断部,其根据提取出的振动成分来对诊断对象物进行诊断。
