US 2021/0276831 A1 · MONITORING OF THE MECHANICAL CONDITION OF AN ESCALATOR OR A MOVING WALKWAY

Abstract

The application relates to a method for detecting and monitoring the mechanical condition of an escalator or a moving walkway with at least one revolving band and at least one detecting device. The method includes (i) preparing at least one spatial image of at least one section of the revolving band, (ii) selecting at least one region of the spatial image, (iii) comparing the selected region with at least one comparison region, wherein the comparison region is defined by three-dimensional coordinates and represents a virtual space which can be clearly assigned to the selected region, and (iv) generating an alarm signal if the selected region differs from the comparison region by surpassing predetermined limits.

A method for detecting and monitoring the mechanical condition of an escalator or a moving walkway with at least one revolving band and at least one detecting device, the method comprising:

creating at least one spatial image of at least one section of the revolving band,
selecting at least one region of the spatial image,
comparing the selected region with at least one comparison region, the comparison region being defined by three-dimensional coordinates and representing a virtual space that can be clearly assigned to the selected region, and
generating an alarm signal if the selected region differs from the comparison region by surpassing predetermined limits,
wherein the assignment of the comparison region to the selected region is carried out via reference marks which are assigned to fixed components of the escalator or the moving walkway, wherein the reference marks can be identified in the spatial image and in the corresponding comparison region.

An escalator or moving walkway comprising:

a band arranged in a revolving manner;
at least one detecting device for detecting and monitoring a mechanical condition of the escalator or the moving walkway, wherein the detecting device comprises at least one image capturing device configured to generate spatial images, wherein the condition of the revolving band and/or the arrangement of sections of the band relative to fixed components of the escalator or the moving walkway can be detected by the detecting device in that at least one spatial image of a section of the revolving band is generated, distinctive surfaces or edges of the section captured on this image are selectable by a processing unit of the detecting device and are comparable with a three-dimensional comparison region stored in a data storage, wherein that the comparison region can be assigned to the selected region via reference marks, wherein the reference marks are assigned to fixed components of the escalator r the moving walkway and wherein the reference marks are identifiable in the spatial image as well as in the corresponding comparison region.
