Provided is an abnormality detection device of a passenger conveyor. The invention provides a technology which is beneficial to distinguishing abnormal factors of a driving belt of a passenger conveyor, remotely judging proper maintenance and the opportunity of carrying out the maintenance. The passenger conveyor is provided with a driving rotating body which is connected with a driving motor for driving a plurality of steps; a driven rotating body connected to the speed reducer; the annular transmission belt is wound and hung on the driving rotating body and the driven rotating body; and an idle pulley that adjusts the tension of the endless belt. The abnormality detection device of the passenger conveyor detects a first speed serving as the running speed of an annular transmission belt according to the rotating speed of an idle wheel, and detects a second speed serving as the traveling speed of the annular transmission belt according to the traveling time of the annular transmission belt. The amount of elongation of the endless belt is calculated by comparing the first speed and the second speed.

    乘客输送机的异常检测装置。提供在区分乘客输送机的传动带的异常因素而远程判断适当的维护以及进行该维护的时机方面有利的技术。乘客输送机具有:驱动旋转体,其与驱动多个梯级的驱动马达连结;从动旋转体,其与减速器连结;环形传动带,其绕挂于驱动旋转体和从动旋转体上;以及惰轮,其进行环形传动带的张力调整。乘客输送机的异常检测装置根据惰轮的旋转速度检测出作为环形传动带的行驶速度的第一速度,并根据环形传动带的巡回时间检测出作为环形传动带的巡回速度的第二速度,通过比较第一速度和第二速度而运算出环形传动带的伸长量。
