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。
To accurately detect abnormality of a footstep roller and a footstep chain inexpensively while being hardly affected by disturbance.SOLUTION: An escalator abnormality detection device includes a speed detection unit for detecting the traveling speed of an escalator, distance sensors provided in right and left two positions while sandwiching a footstep therebetween to measure a distance up to a rotation shaft of a footstep roller, an abnormality determination unit for detecting abnormality of the footstep roller based on whether or not distance signals output from the distance sensors are in a normal range and detecting abnormality of a footstep chain based on the time difference until the rotation shaft of the footstep roller is detected by the distance sensors provided in the right and left two positions if the speed measured by the speed detection unit is a fixed speed or more, and an abnormality output unit notifying the outside of the abnormality detected by the abnormality determination unit.SELECTED DRAWING: Figure 4
