Belt conveyor intelligent control system and method based on machine vision

Abstract

The invention discloses a belt conveyor intelligent control system and method based on machine vision. The belt conveyor intelligent control system can comprise a coal quantity detection device and acontrol device, the coal quantity detection device comprises a structure light source and an image acquisition device, the structure light source is used for projecting structure light to detected coal on a conveyor belt, and the image acquisition device is used for acquiring real-time images of the detected coal under the structure light; and the control device is connected with the coal quantitydetection device and a belt conveyor control box so as to obtain the real-time images and real-time power of the conveyor belt of the belt conveyor, obtain a first predicted coal quantity according to the real-time images, obtain a second predicted coal quantity according to the real-time power of the conveyor belt, analyze according to the first predicted coal quantity and the second predicted coal quantity to calculate the actual mass of the detected coal, and adjust the running speed of the belt conveyor according to the actual mass. The control system can accurately adjust the running speed of the belt conveyor, so that the belt conveyor runs stably and safely.

Description

technical field [0001] The invention relates to the technical field of coal transportation, in particular to an intelligent control system and control method of a belt conveyor based on machine vision. Background technique [0002] In the prior art, the development of the control technology of the belt conveyor is relatively lagging behind. In order to ensure safe production, the operation control of the belt conveyor is usually only started in advance when there is coal, and delayed parking when there is no coal; Reduced speed operation, but this requires more operators. When the amount of coal suddenly increases, it will cause overweight pressure belt, or the coal material will accumulate too high and fall outside the conveyor belt. [0003] In the related technology, the amount of coal is calculated by sensors such as conveyor belt scales and ultrasonic waves, but the conveyor belt scale is set on the conveyor belt and runs with the conveyor belt, which not only makes the...

[0002] In the prior art, the development of the control technology of the belt conveyor is relatively lagging behind. In order to ensure safe production, the operation control of the belt conveyor is usually only started in advance when there is coal, and delayed parking when there is no coal; Reduced speed operation, but this has high requirements for operators. When the amount of coal suddenly increases, it will cause overweight pressure belt, or excessive coal accumulation will fall outside the conveyor belt

[0003] In the related technology, the amount of coal is calculated by sensors such as conveyor belt scales and ultrasonic waves, but the conveyor belt scale is set on the conveyor belt and runs with the conveyor belt, which not only makes the conveyor belt scale easy to damage, but also the conveyor belt scale is more expensive and costs more. higher
