Abstract (en)
[origin: WO2018177708A1] The invention relates to a method for detecting and monitoring the mechanical state of an escalator or a moving walkway comprising at least one circulating belt and at least one detection device. The method has at least the following steps: generating at least one spatial image of at least one section of the circulating belt; selecting at least one region of the spatial image; comparing the selected region with at least one comparison region, wherein the comparison region is defined by three-dimensional coordinates and represents a virtual area which can be uniquely assigned to the selected region; and generating an alarm signal if the selected region differs from the comparison region such that specified thresholds are exceeded.
