FIELD: physics.
SUBSTANCE: invention relates to computer technology, in particular to a method and a system for automated monitoring of the state of a conveyor belt in terms of detecting anomalous sources of concentrated resistance to movement of the conveyor belt by analysing temperature distribution data on thermograms. Method comprises steps of: obtaining a sequence of frames from an infrared camera arranged so as to obtain thermal images of the surface of the conveyor belt; obtaining temperature distribution for thermograms of the obtained frames of the thermal image of the surface of the conveyor belt; thermal image obtained frames are processed, during which temperature distribution for the obtained frame thermal image of the surface of the conveyor belt is compared with a reference temperature distribution or a given reference value of the temperature distribution parameter, wherein the temperature distribution comes in the form of a histogram built on the basis of the temperature distribution Ti to Ti + ΔT, where T is the tape temperature, and ΔT are discrete temperature intervals; presence of abnormal source of concentrated resistance to movement of conveyor belt is determined, if the value of one or more parameters of the temperature distribution is different from the given reference value for one or more parameters of the temperature distribution and/or the temperature distribution on the thermogram is different from one or more reference temperature distributions corresponding to the operation of the conveyor belt in normal mode, or corresponds to the reference temperature distribution, indicating the occurrence of an abnormal source of concentrated resistance to the movement of the conveyor belt; data on detected abnormal sources of concentrated resistance to movement of conveyor belt are recorded in memory of computing device and/or they are transmitted to external device.
EFFECT: determination of presence of abnormal source of concentrated resistance to movement of conveyor belt by analysis of temperature distribution on thermogram.
