Intelligent monitoring system for monitoring coal conveying belt for of coal conveying system

Abstract

The invention relates to an intelligent monitoring system for monitoring a coal conveying belt of a coal conveying system, comprising a coal particle identification module, a belt sinkage detecting module, a horizontal belt displacement detecting module, a belt conveyor vibration detecting module and a controller, wherein the controller is connected with all the modules in a wired or wireless manner; the coal particle identification module is used for monitoring whether large coal blocks exist on the coal conveying belt by firstly detecting whether coal cutoff occurs and then utilizing a particle image identification technology; the belt sinkage detecting module is used for monitoring whether large coal blocks exist on the coal conveying belt by judging the sinking degree of the belt; the horizontal belt displacement detecting module is used for monitoring whether the coal conveying belt deviates or is torn; the belt conveyor vibration detecting module is used for monitoring whether the coal conveying belt is impacted by the large coal blocks or generates friction with the large coal blocks by detecting the vibrating frequency of a belt conveyor; and the controller sends a braking instruction after receiving an instruction needing to brake the belt conveyor so as to brake the belt conveyor.

Description

technical field [0001] The invention relates to the detection field, in particular to an intelligent monitoring system for monitoring a coal conveying belt of a coal conveying system. Background technique [0002] In industries that need to transport a large amount of coal, such as thermal power generation, iron and steel smelting plants, coal mining plants, coal chemical industry and other industries, coal conveyor belts are widely used. The transportation of coal from the coal pile or coal storage to the designated location, such as the combustion boiler, is generally realized by two-stage coal conveyor belt transmission. The primary coal conveying belt is also called the cantilever belt, which is usually installed on the cantilever belt conveyor. The cantilever belt conveyor is well known to those skilled in the art. , conveyor belt, transmission device, etc., the coal taking device holds a large amount of coal from the coal pile and pours it on the conveyor belt, and th...

AI Technical Summary

Problems solved by technology

[0003] There are many protection and detection methods about coal conveyor belts in the prior art, such as belt transformation method, pressure detection method, pull wire switch detection, X-ray detection method, etc., but there are many problems in these methods, for example: 1. Only the belt is torn 2. The belt needs to be modified, which is very costly and unacceptable to users; 3. The technical means are single and cannot deal with various factors that cause damage to the coal conveyor belt during actual operation. The effect is not obvious, and the life of the coal conveyor belt has not been significantly improved; 4. The detection index is unstable, and the normal state and the fault state cannot be accurately distinguished, and it cannot be practically applied because of its high false alarm rate; Risk factors for belt breakage

[0004] Since the monitoring effect of the existing technology on the coal conveyor belt is not obvious, the life of the coal conveyor belt has not been substantially extended. Therefore, an intelligent monitoring system for the coal conveyor belt is needed, which does not require modification or contact with the coal conveyor belt. , can carry out bulk coal identification, belt deviation, broken belt and tear monitoring, and realize all-round monitoring and protection of coal conveying belt
