The invention discloses a belt longitudinal tearing detection method based on image discontinuous point detection. According to the method, an imaging system is installed under a belt, the optical axis of the imaging system is perpendicular to the non-bearing surface of the belt so that a clear belt surface image can be obtained, the horizontal direction of the image corresponds to the width direction of the belt, and the vertical direction of the image corresponds to the axial direction of the belt; the image is split horizontally at equal intervals, discontinuous points are searched on each split segment, and it is judged that the belt is torn longitudinally when the number of the discontinuous points is larger than a set threshold value. By the adoption of the method, measurement precision is high, sensitivity is high, equipment is simple, low in cost and easy to install and maintain, and abrasion of detection equipment is avoided due to the adoption of non-contact detection.
Description
Belt longitudinal tear detection method based on image discontinuity point detection technical field The invention relates to a method for detecting longitudinal tearing of a belt of a belt conveyor, in particular to a non-contact method for detecting longitudinal tearing of a belt based on image discontinuity point detection. Background technique In coal mine production, the belt conveyor is one of the most important means of transportation. The longitudinal tearing accidents of the belt conveyor occur frequently during the coal conveying process. If it is not found in time, the entire belt will be torn and damaged. cause huge economic losses. At present, the methods for detecting the longitudinal tear of the belt are: impact detection method (detection of impact force propagation in the belt medium), abnormal force detection of idler rollers (analysis of abnormal force of idler rollers), ultrasonic method (detection of ultrasonic transmission in belt medium) , varistor ...
