[0040] The dust detection mechanism 11 detects dust on the surface of the photovoltaic panel based on machine vision. An industrial light source can be used for detection, and a strip light source can be considered. Generally, four strip light sources are used to illuminate from the left, right, front and back. The dust on the surface of the backlight panel is displayed by glancing.

[0041] Or use an industrial camera, the camera resolution also needs to be very high, generally use a camera with more than 10 million pixels, or directly use the top 29 million pixel camera to take pictures;

[0042] It is recommended to use a large-diameter, small-magnification telecentric lens for industrial lenses, which can achieve better image effects. Because cameras generally have high resolutions, their interfaces generally use F-mount or M42 interfaces, so the lens cannot use a conventional C-mount lens.

[0043] As well as visual algorithms through texture analysis, particle analysis and other defect detection algorithms, or develop corresponding algorithms yourself. This type of detection is more troublesome to handle using NI VISION. It is recommended to use software such as Halcon / VisionPro, or develop corresponding algorithms yourself.

[0044] Principle and advantages of use:

[0045] When in use, when the dust detection mechanism 11 detects that there is a lot of dust on the first solar photovoltaic panel 3, it sends the detection information to the control module 5. At this time, the control module 5 sends the information to the mobile device 6. The mobile device 6 issues a cleaning instruction. At this time, the control module 5 controls and adjusts the control valve 19 through the I / O controller 7, so that the water inside the water pipe 1 can be transported, and then the sprinkler head 2 at the end of the water pipe 1 can flush the first solar photovoltaic panel 3. Under the flushing of the water flow, the dust on the first solar photovoltaic panel 3 is washed away, and then the water stains carry the dust and are discharged through the drainage mechanism 4, and the photovoltaic power generation is converted through the second solar photovoltaic panel 10 and the control inverter 8, and then the control inverter 8 is controlled. The voltage is respectively transmitted to the control module 5, the I / O controller 7 and the battery pack 9 for power supply. In the case of bad environment, the battery pack 9 realizes power supply operation for the control module 5 and the I / O controller 7. A water volume detection sensor 22 is installed on the drain pipe 17. When the water flow is drained normally, the water output of the water pipeline 1 and the water discharged by the drain pipe 17 can reach a balance. When the water volume detection sensor 22 detects that the water volume does not reach the predetermined water volume (the water volume discharged by the drain pipe 17 is less than the water output of the water pipeline 1, and there is a possibility of blockage of the pressure water bucket 13. In practice, it is common to be blocked by debris such as leaves and plastic bags), it is necessary to start the micro water pump 20 to pump water, accelerate drainage, and prevent debris such as leaves and plastic bags from blocking the pressure water bucket 13. At the same time, an alarm is issued, and manual inspections are carried out to discharge the debris.
