Embodiment 1

[0029] Such as Figure 1~3 As shown, it is a schematic structural diagram of a conveyor belt longitudinal tear detection device based on dual vision sensors provided in Embodiment 1 of the present invention; it includes a housing 3, and the housing 3 is fixedly equipped with an infrared light emitting module 1, a visible light Emitter module 2, power supply module 5, infrared light detection module 11, visible light detection module 12, collected data preprocessing module 15, storage module 17 and data processing module 16, the described housing is provided with infrared light emission glass window 18, visible light Emitter glass window 19 , infrared light detection glass window 13 , visible light detection glass window 14 and fixed base 4 .

[0030] Such as figure 2 and image 3 As shown, the housing 3 is fixed on the connecting bracket 21 below the upper conveyor belt 20 through the fixed base 4, and the inline beams emitted by the infrared light emitting module 1 and the...

Embodiment 2

[0067] In this embodiment, the width of the detected conveyor belt is 800 mm, and the running speed of the conveyor belt is 6.0 m / s. The device is installed in the middle of the connecting bracket between the conveyor belt racks, and the upper surface of the device is 550mm away from the lower surface of the upper conveyor belt. The frame rate of the collected image is 17 frames / s, and other parameters are the same as those in Example 1. In this example, the detection device can detect the longitudinal tear of the conveyor belt with an accuracy of over 98% when the conveyor belt is running fast.

Embodiment 3

[0069] In this embodiment, the width of the detection conveyor belt is 1600mm, and the running speed of the conveyor belt is 6.0m / s. Two sets of devices are used to install on the left and right sides of the connecting bracket between the large conveyor belt racks respectively. The distance between the upper surface of the device and the lower surface of the upper conveyor belt is 550mm. In this embodiment, two sets of detection devices are used to simultaneously detect the longitudinal tear of the large belt running at high speed, and the detection accuracy rate is above 98%.

[0070] The present invention makes full use of the advantages that infrared light has good thermal imaging and penetrability, and visible light images have better detailed information, reflecting the real environment target situation, and performs feature-level fusion of infrared light images and visible light images to enrich image information , enhance the spectral information of the image, make up f...

Abstract

The invention belongs to the technical field of automatic detection, and particularly relates to a conveying belt longitudinal tearing detection device based on a double visual sensor. The conveying belt longitudinal tearing detection device comprises a shell body, an infrared light emitting module, a visible light emitting module, a power supply module, an infrared light detection module, a visible light detection module, an acquired data preprocessing module, a storage module and a data processing module are fixedly arranged in the shell body, the shell body is fixedly arranged on a connecting support below an upper conveying belt through a fixed base, linear light beams emitted through the infrared light emitting module and the visible light emitting module are received through the infrared light detection module and the visible light detection module respectively after being incident on the upper conveying belt and then sent to the acquired data preprocessing module, the acquired data preprocessing module is used for preprocessing acquired image data and then sending the preprocessed image data to the data processing module, and the data processing module is used for analyzingthe acquired data and judging whether the conveying belt is torn or not. According to the conveying belt longitudinal tearing detection device, the reliability of longitudinal tearing detection of theconveying belt is improved.

Description

technical field [0001] The invention belongs to the technical field of automatic detection, and in particular relates to a conveyor belt longitudinal tear detection device based on dual vision sensors. Background technique [0002] Conveyor belts mainly include ordinary canvas core conveyor belts, synthetic fiber core conveyor belts, steel cord core conveyor belts, etc. With the development of conveyors in the direction of high speed, large scale, ultra-long distance, and large inclination angle, steel cord conveyor belts are more and more widely used. The tensile strength of the steel cord conveyor belt has been greatly improved, but its longitudinal tear resistance has not been improved. It is only the strength of the rubber itself, so it is easy to cause longitudinal tearing. The belt conveyor is the main artery of the production and transportation of factories and mines. Once the longitudinal tear occurs, it will bring great direct and indirect losses, especially for hi...
