[0002] With the global emphasis on clean and renewable energy, photovoltaic power generation, as a primary form of new energy development and utilization, has garnered widespread attention and development. Photovoltaic power generation systems utilize photovoltaic panels to convert solar energy into electricity, providing a clean, renewable energy solution for the power market. However, in practice, the power generation efficiency of photovoltaic panels is affected by a variety of factors, among which the cleanliness of the panel surface is a crucial factor.

[0003] Photovoltaic panels, exposed to the elements for extended periods outdoors, are inevitably eroded by sunlight, rain, wind, and other natural factors, leading to the formation of contamination layers such as dust, dirt, and bird droppings. This contamination layer significantly reduces light penetration, diminishing the amount of solar radiation received by the panels and, consequently, lowering photoelectric conversion efficiency. Existing methods of using drones to sequentially clean photovoltaic panels in a specific direction hinder efficient cleaning of all panels within a predetermined area. Summary of the Invention

[0054] Example 1

[0055] Reference Figure 1 The first embodiment of the present application provides a method for cleaning a photovoltaic power station, characterized by comprising the following steps:

[0056] S10: Obtain original cleanliness information of photovoltaic panels in a preset area.

[0057] Specifically, the original cleanliness information is used to characterize the adhesion of stains on the surface of the photovoltaic panel. The higher the original cleanliness, the smaller the area of ​​dust or stains attached to the surface of the photovoltaic panel, the easier the dust or stains are to be cleaned, and the fewer cleaning resources are consumed in cleaning the dust or stains. Conversely, the larger the area of ​​dust or stains attached to the surface of the photovoltaic panel, the more difficult the dust or stains are to be cleaned, and the more resources are consumed in cleaning the dust or stains.

[0058] S20. Acquire cleaning resources required to clean each photovoltaic panel to a target cleanliness level based on the original cleanliness information.

[0059] By analyzing the cleanliness information of the photovoltaic panel surface, we can further analyze the types of dust or stains attached to the photovoltaic panel surface. The cleanliness of each photovoltaic panel is different, and the cleaning resources required to clean the photovoltaic panel to the target cleanliness are also expected to be different.

[0060] S30. Plan a route for the cleaning equipment based on the cleaning resources required to clean each photovoltaic panel and the upper limit of the resources that the cleaning equipment can carry at one time.

[0061] Due to the varying cleanliness levels of photovoltaic panels, the cleaning equipment can only carry a limited amount of resources at a time. After using up its resources, the cleaning equipment must return to a refueling point to replenish them. The cleaning equipment's movement route is planned based on the resources required to clean each photovoltaic panel in a pre-defined area to the target cleanliness level and the amount of cleaning resources the tilting equipment can carry at a time. The cleaning equipment can be a drone-mounted cleaning device. The drone carries a container for the cleaning resources, which is equipped with a spraying device. The spraying device's head can be equipped with an atomizing nozzle. The spraying device can be equipped with a solenoid valve or other device to control the opening and closing of the spraying device. The spraying device can also be equipped with a pressure pump to control the kinetic energy of the cleaning resource during spraying. The cleaning resource can be cleaning water, and the cleaning equipment also provides a cleaning agent separate from the cleaning water. The drone can be equipped with two spray systems: one for spraying cleaning water and the other for spraying cleaning agent. The cleaning agent capacity can be smaller than the cleaning water capacity, for example, one tenth of the cleaning water capacity.

[0062] Example 2

[0063] Based on Example 1, this embodiment provides a method for cleaning a photovoltaic power station, comprising the following steps:

[0064] S10: Obtain original cleanliness information of photovoltaic panels in a preset area.

[0065] Optionally, the step of obtaining original cleanliness information of photovoltaic panels in a preset area includes:

[0066] S11. Acquire image information of photovoltaic panels within a preset area.

[0067] S12: Divide the image information into several pixel blocks.

[0068] S13. Obtain cleanliness information of the pixel block according to preset characteristic information of the pixel block.

[0069] S14. Obtaining original cleanliness information of the photovoltaic panel based on the cleanliness information of all pixel blocks.

[0070] Specifically, using devices such as high-definition cameras, drones, satellite imagery, or ground-based surveillance cameras, capture images of photovoltaic panels during a preset time period, such as early morning when there is ample sunlight and minimal shadows. Ensure clear images with even lighting to reduce the complexity of post-processing. After acquiring image information of the photovoltaic panel surface, the image acquisition device uploads the information to a server or cloud for processing. Filtering techniques such as Gaussian filtering and median filtering are applied to remove noise and improve image quality. If necessary, color correction is performed to eliminate color deviations caused by varying lighting conditions. The preprocessed image is evenly segmented into several pixel blocks using a preset segmentation size, such as 10x10 pixels or 50x50 pixels. The segmentation size should be based on the size of the photovoltaic panel surface details and the image resolution. By segmenting the image information into several pixel blocks, the image information of the photovoltaic panel can be easily compared with that of a standard photovoltaic panel, allowing for more accurate cleanliness information to be obtained. Based on the characteristics of photovoltaic panel cleanliness, a series of feature information is defined, such as grayscale value, brightness, contrast, and texture features (such as a gray-level co-occurrence matrix). The feature information defined above is extracted for each pixel block. Based on the extracted feature information, the cleanliness of each pixel block is evaluated through a preset algorithm or model such as a machine learning model, threshold judgment, etc. This step may involve comparing with a standard clean sample or a model trained using historical data. The cleanliness information of all pixel blocks is aggregated and spatially integrated according to their position on the photovoltaic panel. The weighted average method, maximum method, minimum method or a custom aggregation strategy can be used to calculate the original cleanliness information of the entire photovoltaic panel. When obtaining the original cleanliness information of the entire photovoltaic panel, it may be necessary to consider the weight differences of different areas of the photovoltaic panel (such as the edge and center).

[0071] S20. Acquire cleaning resources required to clean each photovoltaic panel to a target cleanliness level based on the original cleanliness information.

[0072] Obtain the area of ​​dust or stains on the photovoltaic panel, further analyze the texture of the stains, or the type of stain color, or the depth of the stain color on the photovoltaic panel, determine the type of stain, and further subdivide the stains. Obtain historical data on the cleaning resources required to clean the same area and the same type of stains, process the historical data, calculate the cleaning resources required to clean the same type of stains per unit area, and then calculate the cleaning resources required to clean each photovoltaic panel to achieve the target cleanliness based on the cleanliness information on the photovoltaic panel.

[0073] Optionally, the step of obtaining the cleaning resources required to clean each photovoltaic panel to achieve a target cleanliness according to the original cleanliness information includes:

[0074] S21. Compare the original cleanliness information with the preset cleanliness range.

[0075] Specifically, the preset cleanliness interval defines the cleanliness range of the photovoltaic panel from "relatively clean" to "needs cleaning." This interval is usually determined based on the optimal working conditions and historical maintenance data of the photovoltaic panel performance.

[0076] S22: If the original cleanliness of the photovoltaic panel is greater than the maximum value of the preset cleanliness range, the photovoltaic panel is marked as a photovoltaic panel that does not need to be cleaned.

[0077] When the original cleanliness of the photovoltaic panel is greater than the maximum value of the preset cleanliness range, it means that the surface condition of the photovoltaic panel is good, it will not affect the power generation of the photovoltaic panel, and does not need to be cleaned. In order to improve the cleaning efficiency of the photovoltaic panels in the preset area, the photovoltaic panels that do not need to be cleaned are marked, and the photovoltaic panels that do not need to be cleaned will be excluded in the subsequent cleaning process.

[0078] S23. If the original cleanliness of the photovoltaic panel is less than the minimum value of the preset cleanliness range, mark the photovoltaic panel as a first-class photovoltaic panel.

[0079] If the original cleanliness of a photovoltaic panel is less than the minimum value of the preset cleanliness range, it indicates that the surface condition of the photovoltaic panel is very poor, with dust or stains covering a large area, making cleaning difficult. Directly spraying the photovoltaic panel surface with cleaning equipment will not be able to completely remove the stains, or will require a large amount of cleaning resources. Therefore, a detergent can be used to clean the first type of photovoltaic panels to improve their cleaning efficiency.

[0080] S24. If the original cleanliness of the photovoltaic panel is within the preset cleanliness range, mark the photovoltaic panel as a second-category photovoltaic panel.

[0081] When the original cleanliness of the photovoltaic panel is within the preset cleanliness range, it means that the surface condition of the photovoltaic panel is poor, the area of ​​dust or stains attached to the surface is small and easy to clean, and the surface can be directly sprayed and rinsed by cleaning equipment without the use of detergents, avoiding the need to clean the detergents after using the detergents, which increases the cleaning resources.

[0082] S25. Obtain cleaning resources required for the first and second types of photovoltaic panels to achieve target cleanliness, respectively, based on historical data of resources required for cleaning the first and second types of photovoltaic panels to achieve target cleanliness.

[0083] For ease of understanding, let's take a quantitative example. For example, the factory cleanliness of a photovoltaic panel without any debris on its surface is 100, and the preset cleanliness range is 30-95. If the surface cleanliness of a photovoltaic panel is 96, the panel is marked as a panel that does not require cleaning; if the surface cleanliness of a photovoltaic panel is 10, the panel is marked as a Class I panel; if the surface cleanliness of a photovoltaic panel is 50, the panel is marked as a Class II panel.

[0084] S30. Plan a route for the cleaning equipment based on the cleaning resources required to clean each photovoltaic panel and the upper limit of the resources that the cleaning equipment can carry at one time.

[0085] Optionally, the step of planning a travel route of the cleaning equipment includes:

[0086] S31 . Plan a first route based on the location information of the first type of photovoltaic panels, and send a signal to control a cleaning device to pre-clean the first type of photovoltaic panels along the first route.

[0087] Specifically, when a photovoltaic panel is marked as a first-category photovoltaic panel or a second-category photovoltaic panel, its location information can be obtained by reading the label information of the photovoltaic panel.

[0088] Optionally, the step of pre-cleaning the first type of photovoltaic panels includes:

[0089] S311. The cleaning equipment sprays cleaning resources onto the first type of photovoltaic panels to moisten the first type of photovoltaic panels.

[0090] If the detergent is sprayed directly onto the first type of photovoltaic panels, the surface of the stain may be dry and smooth, and the detergent may not adhere well to the stain, reducing the cleaning effect of the detergent. Therefore, the cleaning resource is first sprayed onto the first type of photovoltaic panels to wet the surface of the first type of photovoltaic panels or the stain, so that the detergent can better adhere to the stain.

[0091] S312: After wetting is completed, a signal is sent to control the cleaning equipment to spray cleaning agent onto the first type of photovoltaic panels to pre-clean the first type of photovoltaic panels.

[0092] The first type of photovoltaic panel is pre-cleaned by spraying a cleaning agent onto the stains. After the second type of photovoltaic panel is cleaned, the first type of photovoltaic panel is cleaned. During this period, the cleaning agent adheres to the surface of the first type of photovoltaic panel, further corroding and soaking the stains, reducing the adhesion of the stains to the first type of photovoltaic panel, making it easier to rinse the first type of photovoltaic panel and remove the stains from the surface of the first type of photovoltaic panel. The cleaning agent can be in the form of an aqueous solution, an emulsion, a suspension, etc., making it easier to spray.

[0093] S32. Obtain first remaining resources of the cleaning equipment according to the resources carried by the cleaning equipment and the resources consumed by the cleaning equipment for pre-flushing the first type of photovoltaic panels.

[0094] Specifically, the resources carried by the cleaning equipment refer to cleaning resources, specifically cleaning water, excluding detergents. The first remaining resources of the cleaning equipment also refer to cleaning resources, excluding detergents.

[0095] S33. Plan a second route based on the location information of the second type of photovoltaic panels and the first remaining resources of the cleaning equipment, and send a signal to control the cleaning equipment to clean the second type of photovoltaic panels along the second route to achieve the target cleanliness.

[0096] The target cleanliness is greater than the maximum value of the preset cleanliness range. For ease of understanding, if the factory cleanliness of the photovoltaic panel surface without debris is 100, and the preset cleanliness range is 30-95, then the target cleanliness can be 97.

[0097] Optionally, the steps of cleaning the second type of photovoltaic panels to achieve a target cleanliness level include:

[0098] S331, determining whether the first remaining resources are sufficient to clean all second-type photovoltaic panels to achieve target cleanliness;

[0099] S332: If the first remaining resources are sufficient to clean all the second-type photovoltaic panels to the target cleanliness, a signal is sent to control the cleaning equipment to clean the second-type photovoltaic panels along the second route to the target cleanliness;

[0100] Specifically, if the first remaining resources carried by the cleaning equipment can clean all the second-type photovoltaic panels, the cleaning equipment does not need to return to the supply point to replenish resources. At this time, the cleaning equipment can directly clean the second-type photovoltaic panels.

[0101] S333. If the first remaining resources are not sufficient to clean all the second-category photovoltaic panels to the target cleanliness, a signal is sent to control the cleaning equipment to clean the second-category photovoltaic panels along the second route to achieve a preset cleanliness. Secondly, a signal is sent to control the cleaning equipment to return to the supply point to replenish cleaning resources. Thirdly, a signal is sent to control the cleaning equipment to clean the second-category photovoltaic panels along the second route to achieve the target cleanliness.

[0102] Specifically, if the first remaining resources carried by the cleaning equipment cannot clean all the second-type photovoltaic panels, it needs to return to the supply point at least once to replenish the cleaning resources. At this time, the first remaining resources can be sprayed onto the second-type photovoltaic panels to clean the surface of the second-type photovoltaic panels to a preset cleanliness level. At the same time, the first remaining resources can also be wetted to reduce the adhesion of the dust or stains on the surface of the second-type photovoltaic panels. This will make it easier for the dust or stains to fall off the surface of the photovoltaic panels when the cleaning resources are replenished. For ease of understanding, a quantitative example is given: the original cleanliness of the surface of the second-type photovoltaic panels is 60, the preset cleanliness is 65, and the target cleanliness is 97.

[0103] S34. After all the second-type photovoltaic panels have been cleaned, a signal is sent to control the cleaning equipment to clean the first-type photovoltaic panels along the first route to achieve the target cleanliness.

[0104] Optionally, after the second type of photovoltaic panels are cleaned, the step of cleaning the first type of photovoltaic panels to achieve a target cleanliness level includes:

[0105] S341. After all the second-type photovoltaic panels are cleaned, obtain a second remaining resource of the cleaning equipment;

[0106] Specifically, the second remaining resources refer to cleaning resources, excluding detergents.

[0107] S342, determining whether the second remaining resources are sufficient to clean all first-type photovoltaic panels to achieve target cleanliness;

[0108] S343: If the second remaining resources are sufficient to clean all the first-type photovoltaic panels to the target cleanliness, a signal is sent to control the cleaning equipment to clean the first-type photovoltaic panels to the target cleanliness along the first route from the end point to the starting point;

[0109] Specifically, at this time, the cleaning equipment does not need to return to the supply point to replenish cleaning resources. After completing the cleaning of the first type of photovoltaic panels along the end point to the starting point of the first line, the cleaning equipment can also be located at the starting point, making it convenient to recycle the cleaning equipment at the starting point.

[0110] S344. If the second remaining resources are not sufficient to clean all the first-class photovoltaic panels to the target cleanliness, a signal is sent to control the cleaning equipment to return to the supply point to replenish cleaning resources, and then a signal is sent to control the cleaning equipment to clean the first-class photovoltaic panels along the starting point to the end point of the first route to the target cleanliness.

[0111] Specifically, the cleaning equipment needs to return to the replenishment point at least once to replenish cleaning resources. At this time, the second remaining resources can be sprayed onto the first type of photovoltaic panels to clean the surface of the first type of photovoltaic panels to the second cleanliness level. At the same time, the dust or stains attached to the surface of the first type of photovoltaic panels can be moistened to reduce the adhesion of the dust or stains. This allows the dust or stains to be more easily removed from the surface of the photovoltaic panels when the cleaning resources are replenished. For ease of understanding, a quantitative example is used: the original cleanliness of the surface of the first type of photovoltaic panels is 30, the second cleanliness is 50, and the target cleanliness is 97.

[0112] In this embodiment, after the drone runs out of power, it needs to return to the warehouse or charging station to replace or recharge the battery. Therefore, during the cleaning of the first type of photovoltaic panels and the second type of photovoltaic panels, the power consumption of the drone is related to the weight of the drone itself, the weight of the carried resources and the flight time. For photovoltaic panels with different cleanliness levels, the resources consumed for cleaning the photovoltaic panels are different. It is necessary to reasonably plan the drone's route to minimize the drone's power consumption and reduce the waste of drone electricity.

[0113] The steps of path planning during the cleaning of the first type photovoltaic panel or the second type photovoltaic panel include:

[0114] According to the location information of photovoltaic panels, a matrix map is established.

[0115] According to the matrix map, obtain the flight time of the cleaning equipment between any two photovoltaic panels;

[0116] Based on the flight time and the cleaning resources required to clean the corresponding photovoltaic panels, the path with the least energy consumption of the cleaning equipment is obtained.

[0117] Specifically, the path of the cleaning equipment that consumes the least energy includes multiple flight paths, and the flight time of each flight path is linearly related to the flight speed of the cleaning equipment;

[0118] The product of the flight time of each flight path and the total weight corresponding to the cleaning equipment is calculated as the path energy consumption of the flight path. The path with the least energy consumption refers to the path with the smallest total path energy consumption.

[0119] Each flight path is connected sequentially, and the cleaning equipment's cleaning resources are gradually consumed during the cleaning process, gradually reducing the total weight of the cleaning equipment. By planning the drone's flight path, the drone's energy consumption is minimized, improving the utilization of the drone's power.
