Embodiment 1

[0024] A laser-assisted conveyor belt tear detection device such as figure 1 As shown, it includes a laser projection device 1 , a video detection device 2 and a microcomputer 3 , and the laser projection device 1 and the video detection device 2 are respectively connected to the microcomputer 3 by communication.

[0025] The laser projection device 1 is arranged above the conveyor belt 4 and is used for projecting a bar-shaped laser to the surface of the conveyor belt 4 , and the bar-shaped laser penetrates the surface of the conveyor belt 4 transversely. The video detection device 2 is aligned with the bar-shaped laser on the conveyor belt 4 and is used for real-time tracking and acquisition of the position and shape of the bar-shaped laser and sending it to the microcomputer 3 . The laser projection device and the video detection device share the same microcomputer, or use different microcomputers respectively.

[0026] The microcomputer 3 judges whether the conveyor belt ...

Embodiment 2

[0029] A detection method based on the above-mentioned laser-assisted conveyor belt tear detection device, specifically comprising:

[0030] The laser projecting device projects a bar-shaped laser to the surface of the moving conveyor belt, and the bar-shaped laser traverses the surface of the conveyor belt transversely.

[0031] The video detection device tracks and acquires the bar laser and its shape in real time and sends it to the microcomputer.

[0032] The detection algorithm module of the microcomputer compares the shape of the real-time bar laser with the shape of the pre-stored bar laser. If they are consistent, the conveyor belt is not torn; if not, the conveyor belt is torn. The shape of the pre-stored bar laser includes horizontal stripes, vertical stripes, and oblique stripes at 45 degrees to the horizontal stripes, so that the tearing in each direction of the conveyor belt will be approximately perpendicular to at least one laser, and the tearing will be approxi...

Abstract

The invention provides a laser-assisted conveyor belt tear detection device. The detection device comprises a laser projection device, a video detection device and a microcomputer, wherein the laser projection device and the video detection device are separately in communication connection with the microcomputer, the laser projection device is arranged above or below a conveyor belt and is used for projecting strip-shaped laser to the upper surface or the lower surface of the conveyor belt, the strip-shaped laser transversely penetrates through the surface of the conveyor belt, and the video detection device is aligned with the strip-shaped laser on the conveyor belt and is used for tracking and acquiring the position and the shape of the strip-shaped laser in real time and sending the same to the microcomputer; and the microcomputer determines whether the conveyor belt is torn or deviated according to the real-time position and the real-time shape of the strip-shaped laser. The invention also provides a laser-assisted conveyor belt tear detection method. According to the device and method, by collecting a laser image projected on the conveyor belt and combining with the detectionalgorithm, whether the conveyor belt is torn is sensitively and accurately detected, and false alarms for traces with different colors on the conveyor belt are avoided.

Description

technical field [0001] The invention belongs to the field of industrial detection, in particular to a laser-assisted conveyor belt tear detection device and method. Background technique [0002] On the production lines of steel mills, mines and ports, as well as in airports, subways and some factories, most of the equipment currently used for item transmission is transported by conveyor belts. The artificial intelligence deep learning algorithm can detect the tearing of the conveyor belt very sensitively, but sometimes there are traces of different colors on the conveyor belt. These traces are not tears, but they look similar to tearing. report, resulting in a high false alarm rate and a high shutdown rate, seriously affecting normal operation. [0003] At present, the conveyor belt has a huge market capacity. The global belt conveyor maintenance market value is about 1.8 trillion yuan / year, and the Chinese belt conveyor maintenance market value is about 600 billion yuan / ye...
