APPARATUS AND METHOD FOR DETECTING TENSION PROBLEM OR MEANDERING PROBLEM OF CONVEYOR BELT ON BASIS OF VISION SENSOR

摘要

A method for detecting the condition of a conveyor belt on the basis of a vision sensor, according to an embodiment of the present invention, comprises the steps of: (a) recognizing, by the vision sensor arranged a certain distance from the conveyor belt, at least one sensing mark marked on the outer surface of the rotating conveyor be (b) comparing, by the vision sensor, a pre-stored sensing mark image in a normal state with a recognized sensing mark image, to determine whether at least one of a tension problem and a meandering problem acting on the conveyor belt has occurred, on the basis of a difference in pixel values between the images; and (c) when at least one problem is detected, transmitting, by the vision sensor, a warning message to a manager terminal, wherein the tension problem refers to a phenomenon in which the conveyor belt operates at a preset tension or less and sags, and the meandering problem refers to a phenomenon in which the direction of the conveyor belt deviates in a direction different from the direction in a normal state.
