The invention provides an escalator abnormity detection device and an escalator abnormity detection method, which are not easy to be influenced by external interference and can detect abnormity of a step roller and a step chain at low cost and high precision. According to the embodiment, the first distance sensor and the second distance sensor are correspondingly arranged at the left and right parts of the step rollers which are arranged at the left and right parts by taking the step as the center. The first distance sensor and the second distance sensor measure the distance from the first distance sensor and the second distance sensor to the rotating shaft of the step roller. The abnormality determination part determines whether there is an abnormality in the step roller based on whether distance signals output from the first and second distance sensors are within a normal range, and determines whether there is an abnormality in the step roller when the travel speed of the escalator detected by the speed detection part is greater than a certain speed. Whether the step chain is abnormal or not is judged on the basis of the time difference until the first distance sensor and the second distance sensor detect the rotating shaft of the step roller.

    本发明提供一种能够不易受到外部干扰的影响,廉价地高精度地检测梯级滚轮以及梯级链的异常的自动扶梯异常检测装置以及自动扶梯异常检测方法。根据实施方式,第1以及第2距离传感器与以梯级为中央而设置在左右两处的梯级滚轮对应地设置在左右两处。所述第1以及第2距离传感器测定从所述第1以及第2距离传感器到所述梯级滚轮的旋转轴的距离。异常判定部基于从所述第1以及第2距离传感器输出的距离信号是否在正常范围内来判定所述梯级滚轮有无异常,并且在由速度检测部检测到的自动扶梯的行进速度为一定速度以上的情况下,基于到所述第1以及第2距离传感器检测到所述梯级滚轮的旋转轴为止的时间差来判定梯级链有无异常。
