Embodiment 1
[0039] Such as figure 1 and figure 2As shown, the belt conveyor belt tear state detection system includes an image acquisition unit, a defect location unit, a transmission unit and a data processing unit; wherein,
[0040] The imaging unit includes an image acquisition device 2 arranged on one side of the belt and a laser light source 1 arranged on the adjacent side of the image acquisition device; specifically,
[0041] The image acquisition device 2 is a camera arranged in a protective cover and a zoom lens matched with the camera. The installation height of the image acquisition device 2 is lower than the installation height of the belt, and the camera lens faces the non-working surface of the belt (ie, the back of the belt) Set so that the width of the captured image exceeds the width of the belt;
[0042] In this embodiment, since the installation height of the belt is 450mm, the installation height of the image acquisition equipment is 300mm, which is lower than the i...
Embodiment 2
[0056] Such as image 3 As shown, a detection method implemented by a belt conveyor belt tear state detection system, the specific steps are as follows:
[0057] S1. Use the imaging unit to continuously acquire images of the non-working surface of the belt with 11 parallel laser rays at the same image acquisition frequency; wherein, the distance between two adjacent laser rays is 20 mm;
[0058] Among them, since the position of the laser light relative to the camera is fixed, the position of the laser light in the image is also fixed after the installation is completed, so the camera's setting position is adjusted to each laser light on the image collected during the debugging stage Keep the same length, brightness and clarity, and each laser line has no breakpoints, such as Figure 4 As shown; if the image acquisition range is large, the target image can also be intercepted in the image collected by the camera by setting the coordinate position of the target image to obtain...
