The invention relates to a diagnostic device of a passenger conveyor, and aims to obtain a diagnostic device of an escalator capable of improving diagnostic accuracy. The diagnostic device (4) of the escalator records a signal acquired from the acquisition object detector after the escalator is installed as reference data. The diagnostic device (4) records, as diagnostic data, a signal acquired from the acquisition target detector after recording the reference data. The diagnostic device (4) determines the presence or absence of an abnormality in the target device by comparing the diagnostic data and the reference data during operation in the normal operation mode. The detector group (20) includes at least one of a speed detector, a state detector, a current detector, and a voltage detector.

    乘客输送机的诊断装置,目的在于获得能够提高诊断精度的自动扶梯的诊断装置。自动扶梯的诊断装置(4)将在自动扶梯安装后从取得对象检测器取得的信号记录为基准数据。诊断装置(4)将在记录基准数据之后从取得对象检测器取得的信号记录为诊断数据。诊断装置(4)在通常运转模式下的运转中通过比较诊断数据和基准数据来判定对象设备有无异常。检测器组(20)包含速度检测器、状态检测器、电流检测器和电压检测器中的至少任意一个。
