An online detection device and detection method for surface cracks on a conveyor belt

Abstract

The invention relates to a conveying belt surface crack online detection device. The conveying belt surface crack online detection device comprises a body frame, a background light source, projection light sources, an area array CCD camera and a processing industrial personal computer, wherein the processing industrial personal computer is connected with a remote monitoring computer. The body frame comprises an upper frame body and a lower frame body, a conveying belt is installed between the upper frame body and the lower frame body, the processing industrial personal computer is configured to be used for storing and processing collected original conveying belt surface crack images, and the remote monitoring computer is configured to be used for performing level distinction on the processed conveying belt surface images and judging the crack degree of the conveying belt. By means of the conveying belt surface crack online detection device and a detection method, the functions of automatic online conveying belt image collection, conveying belt image processing, image transmission, automatic focusing of collecting camera optical lenses and the like are achieved, the detection means of traditionally judging cracks of a conveying belt through man determination is changed, and the effect of monitoring the coal conveying belt of a coal system is improved.

Description

technical field [0001] The invention relates to the detection field, in particular to an online detection device and detection method for surface cracks on a conveyor belt. Background technique [0002] Conveyor belts are widely used in engineering construction, freight transportation, coal transportation, etc. It can conveniently and quickly transport various types of objects from one place to another, replacing the physical labor of manual handling, especially in places where the environment is particularly harsh, such as The transportation of coal raw materials in coal mines is limited by the geographical environment, the road surface of the transportation mine is uneven, the mine is deep, and it is not conducive to manual movement. Therefore, the automatic coal transportation method using the conveyor belt has promoted the development of the mining industry. The development of automation has brought huge economic profits to the society. Coal mining is the medium and long...

[0002] Conveyor belts are widely used in engineering construction, freight transportation, coal transportation, etc. It can conveniently and quickly transport various types of objects from one place to another, replacing the physical labor of manual handling, especially in places where the environment is particularly harsh, such as The transportation of coal raw materials in coal mines is limited by the geographical environment, the road surface of the transportation mine is uneven, the mine is deep, and it is not conducive to manual movement. Therefore, the automatic coal transportation method using the conveyor belt has promoted the development of the mining industry. The development of automation has brought huge economic profits to the society. Coal mining is the medium and long-term development demand of the country, and the mining time is long. This requires the assessment of the high safety characteristics of various equipment for coal mining. The same is true for the conveyor belt transportation of coal mines. It needs to have high safety and reliability. However, under the long-term working conditions, the conveyor belt often has friction cracks. If it is not found in time, it is easy to break, which will lead to the paralysis of coal transportation in the mine. Therefore, an online automatic detection is needed. Conveyor belt crack status, timely alarm processing

[0003] Due to factors such as high dust concentration, high flammable gas concentration, and large static electricity during coal transportation in the coal mine operating environment, it is not conducive to manual direct observation of the cracks on the conveyor belt.
