Embodiment Construction

[0021] Several embodiments of the present invention are discussed in detail below with reference to the accompanying drawings.

[0022] figure 1 The basic steps of the conveyor belt automatic detection method of the present invention are schematically shown. As shown in the figure, the automatic detection method 100 of the conveyor belt using X-ray imaging technology of the present invention mainly includes the following steps.

[0023] Step 101: X-rays are used to perform perspective imaging on the first section of the running conveyor belt to obtain a first image.

[0024] Step 102: Obtain first histogram information from the first image, the histogram information is obtained through histogram equalization, and histogram equalization is a method for adjusting contrast by using image histogram in the field of image processing , which is usually used to increase the local contrast of many images, especially when the contrast of the useful data of the image is quite close. By...

Abstract

The invention provides an automatic detection method, utilizing the X-ray imaging technology, for a conveying belt. The automatic detection method includes: subjecting a first section of the operating conveying belt to X-ray imaging to acquire a first image; acquiring first histogram information from the first image; subjecting a second section, subsequent to the first section, of the conveying belt to X-ray imaging to acquire a second image; acquiring second histogram information from the second image; extracting multiple peaks from the first histogram information and the second histogram information; mutually correcting positions of the first image and the second image according to the multiple peaks from the first histogram information and the second histogram information; and comparing the corrected first image with the corrected second image to determine whether a metal core cable of the conveying belt is broken or not. The metal core cable inside the conveying belt can be directly observed by the aid of X-ray imaging, and faults such as cable breakage can be observed conveniently and accurately by means of digital image comparison.

Description

technical field [0001] The invention relates to the field of conveyor belts, in particular to an automatic detection method for conveyor belts. Background technique [0002] Conveyor belts with traction elements generally include traction elements, load bearing members, driving devices, tensioning devices, redirecting devices, supports, and the like. The traction parts are used to transmit the traction force, and conveyor belts, traction chains or rigid ropes can be used; the load-bearing components are used to hold materials, such as hoppers, brackets or spreaders, etc.; The brake (stopper) and other components; the tension device generally has two types of screw type and heavy hammer type, which can keep the traction part at a certain tension and sag to ensure the normal operation of the conveyor belt; the support part is used to support the traction part or load Components, rollers, rollers, etc. can be used. [0003] For conveyor belts with metal core cables, the metal...
