METHOD AND DEVICE FOR MONITORING TECHNICAL CONDITION OF CONVEYOR BELT ELEMENTS Russian patent published in 2022 - IPC B65G43/00 

FIELD: belt conveyor technical condition visual control.

SUBSTANCE: claimed technical solution relates to methods for visual control of the technical condition of the elements of the belt conveyor. The method for monitoring the technical condition of the belt conveyor elements comprises the steps, at which: a) the belt conveyor is filmed using a scanning device containing at least two cameras, while the first camera captures a video image in the visible spectrum, and the second camera ensures the receipt of thermograms due to shooting in the infrared (IR) spectrum; b) the received images are processed during the shooting process using at least one computational algorithm stored in the memory of the scanning device and providing the formation of an augmented reality display process in real time by superimposing thermograms or illuminated areas with a temperature above the threshold T_thr, obtained using the second camera, on top of the images taken by the first camera; c) in the course of image processing at step b), a conveyor element is determined, which is at least one roller or a place of contact of the fixed elements of the conveyor with the conveyor belt, the thermogram of which contains a temperature value exceeding the threshold value T_thr; d) a data packet is formed containing: an image of the detected conveyor element in the visible spectrum, the thermogram of which contains a temperature value exceeding the threshold value T_thr, with a superimposed thermogram or a highlighted area where the temperature is above the threshold value T_thr, maximum and minimum temperatures, geographical coordinates shooting points, date and time; e) storing the generated data packet on the scanning device and transmitting said data packet to the remote control system.

EFFECT: increasing the efficiency of monitoring the technical condition of the belt conveyor elements, by automating and accurately determining the heating of the conveyor elements using video identification in the visible and infrared spectrum, forming an image of the inspected objects using augmented reality technology, as well as identifying the location of the elements by obtaining geo- survey coordinates.
