Description

Technical Field

[0001] The present invention relates to the field of control systems, and in particular to a photovoltaic power generation control system based on solar radiation. Background Art

[0002] The intensity and direction of solar energy are affected by many factors, such as the alternation of day and night, seasonal changes, weather conditions (such as cloud cover, haze, etc.), and geographical location. These factors cause solar radiation to be significantly intermittent and volatile, making it difficult for photovoltaic power generation equipment to output electricity stably. For example, on cloudy or rainy days, the intensity of solar radiation drops significantly, and the efficiency of photovoltaic power generation decreases; on sunny days, the constant change in the position of the sun will cause the angle of light received by the photovoltaic panels to change, affecting the power generation efficiency. Therefore, it is necessary to monitor solar radiation information in real time in order to reasonably regulate photovoltaic power generation equipment so that it is always in the best working condition.

[0003] In the process of regulating photovoltaic power generation equipment, the photovoltaic power generation regulation system will be used.

[0004] The existing photovoltaic power generation control system can only realize simple functions, such as adjusting the angle of photovoltaic panels according to the position of the sun, etc. It is unable to comprehensively and accurately monitor and analyze various information of the photovoltaic power generation system, and it is difficult to meet the control needs in complex environments, which has a certain impact on the use of safety protection systems. Therefore, a photovoltaic power generation control system based on solar radiation is proposed. Summary of the invention

[0005] The technical problem to be solved by the present invention is: how to solve the problem that the existing photovoltaic power generation control system can only realize simple functions, such as adjusting the angle of photovoltaic panels according to the position of the sun, and cannot comprehensively and accurately monitor and analyze various information of the photovoltaic power generation system, and it is difficult to meet the control needs in complex environments. A photovoltaic power generation control system based on solar radiation is provided.

[0006] The present invention solves the above technical problems through the following technical solutions, which include: A solar radiation collection module is arranged around the photovoltaic power generation equipment to collect solar radiation information; Power generation equipment collection module, used to collect photovoltaic power generation equipment information; Environmental collection module, used to collect environmental information of photovoltaic power generation equipment; An image acquisition module is provided on the solar radiation acquisition module and the photovoltaic power generation device, and is used to acquire image information of the solar radiation acquisition module and image information of the photovoltaic power generation device; A data processing module is used to process solar radiation information, photovoltaic power generation equipment information, image information of the solar radiation collection module, image information of the photovoltaic power generation equipment and information about the environment in which the photovoltaic power generation equipment is located, and generate photovoltaic equipment control information, photovoltaic power generation equipment auxiliary control information and environmental warning information; The information sending module is used to send photovoltaic equipment control information, photovoltaic power generation equipment auxiliary control information and environmental warning information to a preset receiving terminal.

[0007] Furthermore, the setting process of the solar radiation collection module is as follows: At least 8 groups of solar radiation collection modules are provided, and the 8 groups of solar radiation collection modules are arranged in a circular array around the photovoltaic panel, and the number of solar radiation collection modules in each group is two; A group of solar radiation collection modules are respectively arranged in the east, southeast, south, southwest, west, northwest, north and northeast directions; The distance between two solar radiation collection modules in each group of solar radiation collection modules must be within a preset range; Each solar radiation collection module must be located outside the abnormal area, and the distance between each solar radiation collection module and the abnormal area must not be greater than a preset value; Each solar radiation collection module consists of a solar radiation collection device and a micro photovoltaic power generation device.

[0008] Furthermore, the determination process of the abnormal area is as follows: collecting image information of the photovoltaic power generation equipment from top to bottom in different time periods, taking the center point of the photovoltaic power generation equipment as the first reference point, extracting the shadow of the photovoltaic power generation equipment from the image information of the photovoltaic power generation equipment, and extracting the point farthest from the first reference point from the shadow of the photovoltaic power generation equipment as the second reference point; The first reference point and the second reference point are connected to obtain a reference line, and the length L of the reference line is measured. Then, a circle is drawn with the first reference point as the center and the length L as the radius. The area within the circle is the abnormal area.

[0009] Furthermore, the solar radiation collection module collects solar radiation information in the following process: The solar radiation collection device in the solar radiation collection module collects solar radiation intensity information and solar radiation inclination in real time, and the micro photovoltaic power generation equipment collects real-time power generation efficiency to obtain real-time power generation efficiency; Calculate and process the solar radiation intensity information and solar radiation inclination angle collected by two solar radiation collection devices; When the deviation between the solar radiation intensity information collected by the two solar radiation collection devices is within a preset range, and the deviation between the solar radiation inclination angles collected by the two solar radiation collection devices is also within a preset range, that is, one of the two solar radiation intensity information is selected to be derived as the finally selected solar radiation intensity information, and one of the two solar radiation inclination angles is selected to be derived as the finally selected solar radiation inclination angle; When the deviation between the solar radiation intensity information collected by the two solar radiation collection devices exceeds a preset range or the deviation between the solar radiation inclination angles collected by the two solar radiation collection devices exceeds a preset range, it is determined that re-collection is required; The process of obtaining the real-time power generation efficiency is as follows: collecting the initial power of the micro photovoltaic power generation equipment and the power after a preset time; The difference between the power after the preset time and the initial power of the micro photovoltaic power generation equipment is calculated to obtain the real-time power generation; Calculate the ratio of real-time power generation to the preset duration, that is, obtain the power generation efficiency; Real-time solar radiation intensity information, solar radiation inclination and power generation efficiency constitute solar radiation information.

[0010] Furthermore, the process of acquiring the photovoltaic equipment control information is as follows: Extracting photovoltaic power generation equipment information, which includes equipment inclination and equipment direction; Then extract the solar radiation information, that is, extract the solar radiation information collected by all solar radiation collection devices, and sort them in order from large to small; Extract the directions corresponding to the maximum value and the second largest value in the solar radiation information, namely the optimal direction and the suboptimal direction; Then, the angle difference between the device direction and the optimal direction is calculated to obtain a first angle difference, and the angle difference between the device direction and the suboptimal direction is calculated to obtain a second angle difference; When the first angle difference and the second angle difference are both greater than the preset value, photovoltaic device control information is generated; At this time, the power generation efficiency in the optimal direction and the power generation efficiency in the suboptimal direction are extracted; When the power generation efficiency in the optimal direction is greater than the power generation efficiency in the suboptimal direction, the content of the photovoltaic equipment control information is to adjust the direction of the photovoltaic power generation equipment to the optimal direction; When the power generation efficiency in the optimal direction is lower than the power generation efficiency in the suboptimal direction, the content of the photovoltaic equipment control information is to adjust the direction of the photovoltaic power generation equipment to the suboptimal direction.

[0011] Furthermore, after the photovoltaic power generation equipment is adjusted to the corresponding direction, the difference between the equipment inclination angle and the solar radiation inclination angle is extracted to obtain the inclination difference. When the inclination difference exceeds the preset range, the photovoltaic equipment control information is generated. At this time, the photovoltaic equipment control information is to adjust the inclination angle of the photovoltaic power generation equipment to within the deviation of ±5° from the solar radiation inclination angle. Before generating photovoltaic equipment control information, it is necessary to first perform energy status detection, that is, first collect the current storage capacity of photovoltaic power generation energy storage equipment, calculate the ratio of the current storage capacity of the energy storage equipment to the full state capacity, and obtain the evaluation ratio; When the evaluation ratio is greater than the preset value, no photovoltaic equipment control information is generated.

[0012] Furthermore, the process of obtaining the auxiliary control information of the photovoltaic power generation equipment is as follows: Extracting image information of the solar radiation collection module and image information of the photovoltaic power generation equipment; The insect model is imported into the image information of the solar radiation collection module, the number of times the insect model appears is extracted from the image information of the solar radiation collection module, marked as F1, and then the image duration F2 is extracted; Calculate the ratio Ff of F1 and F2, that is, obtain the insect appearance parameter Ff. When the insect appearance parameter Ff is greater than a preset value, the auxiliary control information of the photovoltaic power generation equipment is generated. At the same time, the image information of the solar radiation collection module is processed, and the solar radiation collection module is equally divided into a preset number of areas. When the number of insect models identified in any area is greater than the preset value, auxiliary control information of the photovoltaic power generation equipment is generated; The process of processing the image information of the photovoltaic power generation equipment to generate the auxiliary control information of the photovoltaic power generation equipment is the same as the process of processing the image information of the solar radiation collection module to generate the auxiliary control information of the photovoltaic power generation equipment.

[0013] Furthermore, the specific process of obtaining environmental warning information is as follows: Extract the collected environmental information of the photovoltaic power generation equipment, which includes environmental temperature information, environmental wind force information and environmental abnormal object information; The ambient temperature information is extracted. When the ambient temperature information is greater than a preset value and the ambient wind force information is abnormal, an environmental warning message is generated; When the number of environmental anomalies exceeds the preset value, an environmental warning message is generated.

[0014] Furthermore, the process of collecting the environmental wind force information is as follows: wind force collection equipment is set in the east, west, south and north directions of the photovoltaic cell; When the ambient temperature information is greater than the preset value, and the wind force information collected by the wind force collection devices set in the four directions of east, west, south and north are all less than the preset value, it means that the ambient wind force information is abnormal; The process of obtaining the number of environmental anomalies is as follows: extract the center position of the photovoltaic power generation equipment, use this position as the reference point, draw a circle with a preset length as the radius, obtain the detection area, and collect the number of objects in the detection area whose height is greater than the preset height, that is, obtain the number of environmental anomalies.

[0015] Compared with the prior art, the present invention has the following advantages: the photovoltaic power generation control system based on solar radiation can monitor the photovoltaic power generation system in all directions in real time, and the radiation collection modules distributed in the ring array can cover the radiation data in 8 main directions, thus ensuring the comprehensiveness and accuracy of data collection; Based on the optimal / suboptimal direction selection algorithm, the photovoltaic panel orientation is dynamically adjusted to improve the efficiency of light energy capture. The dynamic tilt calibration mechanism makes the photovoltaic panel tilt match the solar radiation tilt in real time. The validity of the radiation data is verified through micro-power generation equipment. The intelligent judgment technology of abnormal areas avoids the equipment being arranged in the blocked area. Energy storage status assessment mechanism ensures the economic efficiency of control operations, and dual-device redundancy verification improves data credibility; It can also detect biological contamination risks in a timely manner, and conduct multi-directional wind monitoring combined with high temperature warning to prevent hot spot effects and insufficient heat dissipation; The obstacle detection mechanism is set up to avoid occlusion risks in advance, making the system more worthy of promotion and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 It is a system block diagram of the present invention. DETAILED DESCRIPTION

[0017] The following is a detailed description of an embodiment of the present invention. This embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation method and a specific operation process are given, but the protection scope of the present invention is not limited to the following embodiment.

[0018] like Figure 1 As shown, this embodiment provides a technical solution: a photovoltaic power generation control system based on solar radiation, including: A solar radiation collection module is arranged around the photovoltaic power generation equipment to collect solar radiation information; Power generation equipment collection module, used to collect photovoltaic power generation equipment information; Environmental collection module, used to collect environmental information of photovoltaic power generation equipment; An image acquisition module is provided on the solar radiation acquisition module and the photovoltaic power generation device, and is used to acquire image information of the solar radiation acquisition module and image information of the photovoltaic power generation device; A data processing module is used to process solar radiation information, photovoltaic power generation equipment information, image information of the solar radiation collection module, image information of the photovoltaic power generation equipment and information about the environment in which the photovoltaic power generation equipment is located, and generate photovoltaic equipment control information, photovoltaic power generation equipment auxiliary control information and environmental warning information; The information sending module is used to send photovoltaic equipment control information, photovoltaic power generation equipment auxiliary control information and environmental warning information to a preset receiving terminal.

[0019] The setting process of the solar radiation collection module is as follows: At least 8 groups of solar radiation collection modules are provided, and the 8 groups of solar radiation collection modules are arranged in a circular array around the photovoltaic panel, and the number of solar radiation collection modules in each group is two; A group of solar radiation collection modules are respectively arranged in the east, southeast, south, southwest, west, northwest, north and northeast directions; The distance between two solar radiation collection modules in each group of solar radiation collection modules must be within a preset range; Each solar radiation collection module must be located outside the abnormal area, and the distance between each solar radiation collection module and the abnormal area must not be greater than a preset value; Each solar radiation collection module consists of a solar radiation collection device and a micro photovoltaic power generation device; Eight groups of solar radiation collection modules are distributed in a circular array around the photovoltaic panels in the directions of due east, due southeast, due south, due southwest, due west, due northwest and due north, and can collect solar radiation information from multiple directions.

[0020] The solar radiation conditions in different directions will vary due to factors such as time, season and surrounding environment. Such a layout can ensure that solar radiation data in all directions can be obtained at different times of the day and different seasons of the year, so as to have a more comprehensive understanding of the solar radiation distribution around the photovoltaic panels and provide a more accurate basis for subsequent photovoltaic power generation regulation.

[0021] Each group is equipped with two solar radiation collection modules, and the distance between them is required to be within a preset range. The data collected by the two collection modules can be verified with each other. If the deviation between the solar radiation intensity information and the solar radiation inclination angle collected by the two collection modules is within a preset range, one of the two data can be selected as the final selected data, which helps to improve the reliability and accuracy of the data. If the deviation exceeds the preset range, it can be determined that the data needs to be collected again to avoid the use of erroneous data due to the failure or abnormality of a single collection module.

[0022] It is required that each solar radiation collection module be located outside the abnormal area, and the distance from the abnormal area shall not be greater than the preset value. Abnormal areas are usually areas that may have an adverse effect on solar radiation collection, such as areas that will produce shadows. By avoiding these areas, it can be ensured that the collection module collects normal solar radiation information, avoiding inaccurate radiation data collected due to factors such as shadows, thereby ensuring the scientificity and effectiveness of subsequent photovoltaic power generation control decisions based on these data.

[0023] Each solar radiation collection module consists of a solar radiation collection device and a micro photovoltaic power generation device. The solar radiation collection device is responsible for collecting solar radiation intensity information and solar radiation inclination, while the micro photovoltaic power generation device collects real-time power generation efficiency. Combining and analyzing these two types of data can provide a more comprehensive understanding of the relationship between solar radiation and photovoltaic power generation efficiency. For example, under the same solar radiation conditions, the power generation efficiency of micro photovoltaic power generation devices in different directions may be different. By comparing and analyzing these data, the most suitable orientation and inclination of photovoltaic panels can be found, thereby optimizing the operation of photovoltaic power generation equipment and improving power generation efficiency.

[0024] The determination process of the abnormal area is as follows: collecting the image information of the photovoltaic power generation equipment from top to bottom at different time periods, taking the center point of the photovoltaic power generation equipment as the first reference point, extracting the shadow of the photovoltaic power generation equipment from the image information of the photovoltaic power generation equipment, and extracting the point farthest from the first reference point from the shadow of the photovoltaic power generation equipment as the second reference point; The first reference point and the second reference point are connected to obtain a reference line, and the length L of the reference line is measured. Then, a circle is drawn with the first reference point as the center and the length L as the radius, and the area within the circle is the abnormal area; The above process takes into account the shadow changes in different time periods, and can comprehensively identify areas that may affect the solar radiation collection, avoiding the solar radiation collection module from collecting inaccurate data due to shadow obstruction, and providing a reliable basis for subsequent photovoltaic power generation regulation.

[0025] Clearly define abnormal areas and provide clear standards for the installation location planning of equipment such as solar radiation collection modules, so as to facilitate the reasonable arrangement of equipment and avoid areas that may be blocked.

[0026] It can effectively avoid the situation where photovoltaic power generation equipment does not receive enough solar radiation due to shadow blocking, reduce power generation losses, and improve the power generation efficiency of the entire photovoltaic power generation system.

[0027] The solar radiation collection module collects solar radiation information in the following process: The solar radiation collection device in the solar radiation collection module collects solar radiation intensity information and solar radiation inclination in real time, and the micro photovoltaic power generation equipment collects real-time power generation efficiency to obtain real-time power generation efficiency; Calculate and process the solar radiation intensity information and solar radiation inclination angle collected by two solar radiation collection devices; When the deviation between the solar radiation intensity information collected by the two solar radiation collection devices is within a preset range, and the deviation between the solar radiation inclination angles collected by the two solar radiation collection devices is also within a preset range, that is, one of the two solar radiation intensity information is selected to be derived as the finally selected solar radiation intensity information, and one of the two solar radiation inclination angles is selected to be derived as the finally selected solar radiation inclination angle; When the deviation between the solar radiation intensity information collected by the two solar radiation collection devices exceeds a preset range or the deviation between the solar radiation inclination angles collected by the two solar radiation collection devices exceeds a preset range, it is determined that re-collection is required; The process of obtaining the real-time power generation efficiency is as follows: collecting the initial power of the micro photovoltaic power generation equipment and the power after a preset time; The difference between the power after the preset time and the initial power of the micro photovoltaic power generation equipment is calculated to obtain the real-time power generation; Calculate the ratio of real-time power generation to the preset duration, that is, obtain the power generation efficiency; Real-time solar radiation intensity information, solar radiation inclination angle and power generation efficiency constitute solar radiation information; Each group is equipped with two solar radiation collection devices to compare the collected solar radiation intensity information and solar radiation inclination. When the deviation between the two is within the preset range, it means that the data is reliable and one of them is selected as the final result. If the deviation exceeds the range, the data is collected again, avoiding erroneous data caused by single equipment failure, measurement error and other factors from entering the subsequent analysis process, thereby ensuring the accuracy and reliability of the collected data.

[0028] In addition to solar radiation intensity and inclination, the real-time power generation efficiency of micro photovoltaic power generation equipment is also taken into comprehensive consideration. The power generation efficiency is closely related to the solar radiation conditions. By comparing the power generation efficiency and radiation data of different devices, the accuracy of the radiation data can be further verified to ensure that the collected information can truly reflect the actual solar radiation conditions.

[0029] The collection process covers three key parameters: solar radiation intensity information, solar radiation inclination, and power generation efficiency. These parameters are interrelated and each has its own significance. Radiation intensity reflects the energy of solar energy, radiation inclination affects the angle at which photovoltaic equipment receives solar energy, and power generation efficiency directly reflects the actual power generation capacity of photovoltaic equipment under current radiation conditions. Combining these parameters into solar radiation information provides comprehensive and rich basic data for the photovoltaic power generation control system, which helps to make subsequent control decisions more accurately.

[0030] Solar radiation collection equipment and micro photovoltaic power generation equipment both collect data in real time, which can timely reflect the dynamic changes of solar radiation and power generation efficiency. The environment and solar radiation conditions of the photovoltaic power generation system may change at any time. The real-time collected data can allow the system to perceive these changes in time and make corresponding adjustments quickly to adapt to different working conditions and improve power generation efficiency and system stability.

[0031] When the data deviation of the two acquisition devices exceeds the preset range, it is determined to re-collect data. This mechanism enables the system to flexibly respond to various abnormal situations, such as equipment failure, external interference, etc. By re-collecting data in a timely manner, the system can quickly restore the normal data collection process, ensure the continuity and effectiveness of the data, and thus improve the adaptability of the entire photovoltaic power generation control system to complex environments.

[0032] The process of obtaining the photovoltaic equipment control information is as follows: Extracting photovoltaic power generation equipment information, which includes equipment inclination and equipment direction; Then extract the solar radiation information, that is, extract the solar radiation information collected by all solar radiation collection devices, and sort them in order from large to small; Extract the directions corresponding to the maximum value and the second largest value in the solar radiation information, namely the optimal direction and the suboptimal direction; Then, the angle difference between the device direction and the optimal direction is calculated to obtain a first angle difference, and the angle difference between the device direction and the suboptimal direction is calculated to obtain a second angle difference; When the first angle difference and the second angle difference are both greater than the preset value, photovoltaic device control information is generated; At this time, the power generation efficiency in the optimal direction and the power generation efficiency in the suboptimal direction are extracted; When the power generation efficiency in the optimal direction is greater than the power generation efficiency in the suboptimal direction, the content of the photovoltaic equipment control information is to adjust the direction of the photovoltaic power generation equipment to the optimal direction; When the power generation efficiency in the optimal direction is lower than the power generation efficiency in the suboptimal direction, the content of the photovoltaic equipment control information is to adjust the direction of the photovoltaic power generation equipment to the suboptimal direction.

[0033] Accurately locate the best direction: By sorting the information collected by all solar radiation collection devices and finding the optimal and suboptimal directions, the direction in which the photovoltaic power generation equipment obtains the most solar radiation can be accurately determined. When the angle difference between the current direction of the device and these two directions is large, adjustments can be made to allow the device to receive as much solar energy as possible, thereby improving power generation efficiency.

[0034] Combined with power generation efficiency decision: not only consider the solar radiation intensity, but also compare the power generation efficiency of the optimal and suboptimal directions, and choose the direction with higher power generation efficiency as the adjustment target. This is because the actual power generation efficiency will be affected by many factors, and adjustment based solely on radiation intensity may not be the best choice. Combining power generation efficiency can make more scientific decisions and further improve power generation efficiency.

[0035] Realize intelligent control The basis for automated adjustment is clear: the entire process is based on clear rules and calculations, such as calculating angle differences, comparing power generation efficiency, etc. As long as the corresponding conditions are met, the control information is automatically generated, realizing automated intelligent control of photovoltaic equipment, reducing manual intervention, and improving the timeliness and accuracy of control.

[0036] Dynamically adapt to environmental changes: Solar radiation conditions will change dynamically with time, weather and other factors. This process extracts and analyzes solar radiation information in real time, and can adjust the direction of photovoltaic equipment in time according to environmental changes, so that the equipment is always in the best working condition.

[0037] Set a preset value for the angle difference, and make adjustments only when the angle difference is greater than the preset value, avoiding frequent small adjustments, reducing mechanical wear and energy consumption of the equipment, and reducing equipment maintenance costs and failure risks.

[0038] By making scientific decisions and choosing the best adjustment direction, we can ensure that the equipment can achieve better power generation effects after adjustment, realize the rational use of resources, and improve the input-output ratio.

[0039] When the photovoltaic power generation equipment is adjusted to the corresponding direction, the difference between the equipment inclination angle and the solar radiation inclination angle is extracted to obtain the inclination difference. When the inclination difference exceeds the preset range, the photovoltaic equipment control information is generated. At this time, the content of the photovoltaic equipment control information is to adjust the inclination angle of the photovoltaic power generation equipment to within the deviation of ±5° from the solar radiation inclination angle. Before generating photovoltaic equipment control information, it is necessary to first perform energy status detection, that is, first collect the current storage capacity of photovoltaic power generation energy storage equipment, calculate the ratio of the current storage capacity of the energy storage equipment to the full state capacity, and obtain the evaluation ratio; When the evaluation ratio is greater than the preset value, no photovoltaic equipment control information is generated.

[0040] The above process can further improve the power generation efficiency by extracting the difference between the device inclination and the solar radiation inclination. When the difference exceeds the preset range, the device inclination is adjusted to within ±5° of the solar radiation inclination. The solar radiation inclination changes with time and season. Matching the photovoltaic device inclination with it can enable the photovoltaic panels to receive sunlight vertically to the greatest extent, increase the amount of solar radiation received per unit area, and thus significantly improve the photovoltaic power generation efficiency.

[0041] The mechanism of real-time monitoring and adjusting the tilt angle can enable photovoltaic equipment to dynamically adapt to changes in the position of the sun in the sky, ensuring that the equipment is always at the optimal angle to receive solar energy. Compared with photovoltaic equipment with fixed tilt angles, it can achieve better power generation effects in different time periods and seasons.

[0042] Perform energy status detection before generating control information and calculate the evaluation ratio of energy storage equipment; When the evaluation ratio is greater than the preset value, it means that the energy storage device is close to full. At this time, even if the photovoltaic equipment is adjusted to improve the power generation efficiency, the excess electricity cannot be effectively stored. Instead, extra energy will be consumed for equipment adjustment. Therefore, not generating control information can avoid unnecessary energy waste and achieve optimal energy utilization.

[0043] Reducing unnecessary equipment adjustments can reduce mechanical wear and electrical losses of equipment, extend the service life of photovoltaic equipment and related control mechanisms, and reduce equipment maintenance costs and replacement frequency.

[0044] By detecting the energy status, we can avoid continuing to improve the power generation efficiency when the energy storage device is close to full state, effectively prevent the energy storage device from overcharging, protect the performance and safety of the energy storage device, and ensure the stable operation of the entire photovoltaic power generation system.

[0045] Deciding whether to adjust equipment based on the status of the energy storage device helps maintain the balance between power generation, energy storage and electricity consumption in the photovoltaic power generation system, improves the system's adaptability to different operating conditions, and enhances the system's stability and reliability.

[0046] The process of obtaining the auxiliary control information of the photovoltaic power generation equipment is as follows: Extracting image information of the solar radiation collection module and image information of the photovoltaic power generation equipment; The insect model is imported into the image information of the solar radiation collection module, the number of times the insect model appears is extracted from the image information of the solar radiation collection module, marked as F1, and then the image duration F2 is extracted; Calculate the ratio Ff of F1 and F2, that is, obtain the insect appearance parameter Ff. When the insect appearance parameter Ff is greater than a preset value, the auxiliary control information of the photovoltaic power generation equipment is generated. At the same time, the image information of the solar radiation collection module is processed, and the solar radiation collection module is equally divided into a preset number of areas. When the number of insect models identified in any area is greater than the preset value, auxiliary control information of the photovoltaic power generation equipment is generated; The process of processing the image information of the photovoltaic power generation equipment to generate the auxiliary control information of the photovoltaic power generation equipment is the same as the process of processing the image information of the solar radiation collection module to generate the auxiliary control information of the photovoltaic power generation equipment; Biological contamination warning The insect model recognition algorithm is used to monitor the insect aggregation on the surface of photovoltaic equipment in real time, detect biological pollution risks in time, and avoid the reduction of power generation efficiency due to insect shading; The area-divided detection mechanism can locate areas with high insect density, providing precise targets for cleaning operations, reducing maintenance costs and improving efficiency; Adopting the Ff parameter, i.e. the dual-index trigger mechanism of insect occurrence frequency and regional density, combined with dynamic threshold setting, ensures effective early warning under different environmental conditions; At the same time, by performing insect model recognition and analysis, auxiliary control information for photovoltaic power generation equipment is also generated when the preset conditions are met; The specific contents of the preconditions are: Insects are identified through insect model recognition algorithms. When the identified insect species is a spider, auxiliary control information for photovoltaic power generation equipment is directly generated to prompt maintenance personnel to clean up immediately. When spiders appear on photovoltaic power generation equipment, they may make webs on the photovoltaic power generation equipment, which will absorb a lot of dust, leaves and other debris, and will cause more insects to die and fall on the photovoltaic power generation equipment, so timely cleaning is required; The average thickness of spider webs can reach 0.5-2mm, and a single square meter of coverage can reduce light transmittance by 8%-15%. Timely cleaning can avoid continuous attenuation of power generation efficiency; The sticky secretions of spider webs (including spider silk proteins) can absorb PM2.5 and metal particles in the air, forming a complex pollution layer; Timely removal of spiders can delay equipment aging and prevent biodegradation erosion; Spider excrement contains uric acid and protease, and long-term attachment will accelerate the chemical etching of component glass (laboratory data: excrement with a pH value of 5.2 can reduce the light transmittance of glass by 0.7% per year).

[0047] To avoid structural stress concentration, a large spider web can withstand a tensile force of 0.5-1N, which may cause the edge sealing strip of the component to deform and cause the risk of water vapor penetration; When bees are first identified, continuous monitoring is performed to monitor the number of bees that appear within a preset time. When the number of bees that appear within a preset time is greater than a preset value, auxiliary control information for photovoltaic power generation equipment is generated to prompt maintenance personnel to immediately expel the bees. When there are many bees, it means that the bees may build nests on the photovoltaic power generation equipment. Although the conditions of the photovoltaic power generation equipment are not suitable for nesting, this possibility cannot be ruled out, so they also need to be removed; The monitoring is triggered at the early stage of bee gathering, and intervention is carried out before nesting behavior occurs to prevent the nest structure from causing physical pressure on the equipment or damage to the insulation layer; Timely removal of bees can ensure power generation efficiency and reduce shading losses; When bees gather, the surface coverage of a single module can reach 5%-15%, causing the power generation efficiency to drop by 7%-12% instantly. Timely removal can avoid continuous shading.

[0048] Bee feces contains uric acid and sugar, which form a conductive film after drying, which may cause hot spot effects and accelerate component aging.

[0049] When the identified insect species is a snail, the number of its appearance is monitored. When the number is greater than the preset value, auxiliary control information of photovoltaic power generation equipment is generated to prompt maintenance personnel to immediately clean the snail and clean the photovoltaic equipment; The snail's body and excrement will cover the surface of the solar panel, reducing the light transmittance and resulting in a decrease in power generation efficiency. Experimental data shows that partial shading can reduce power generation by 10%-30%.

[0050] The film formed by the snail mucus after drying will absorb dust, further reducing the light transmittance. Long-term accumulation may lead to a continuous decline in power generation.

[0051] If a snail dies on a photovoltaic panel, the friction of its shell may scratch the surface of the solar panel glass, destroy the anti-reflective coating, and affect the light transmission performance and UV resistance; When snails gather around brackets or junction boxes, they may chew on the sealing strips or insulation materials, causing the equipment to lose its sealing properties. When a snail enters the junction box or inverter, it may cause a short circuit, resulting in equipment damage or even fire hazards.

[0052] Synchronously monitor the image information of the solar radiation collection module and the photovoltaic panels to achieve biological contamination early warning covering the entire system.

[0053] Auxiliary control information can be generated without human intervention, which improves the intelligence level of the system and reduces the workload of operation and maintenance personnel.

[0054] This mechanism combines image recognition with intelligent algorithms to achieve active defense against biological contamination and ensure the continued efficient operation of the photovoltaic power generation system.

[0055] The specific process of obtaining environmental warning information is as follows: Extract the collected environmental information of the photovoltaic power generation equipment, which includes environmental temperature information, environmental wind force information and environmental abnormal object information; The ambient temperature information is extracted. When the ambient temperature information is greater than a preset value and the ambient wind force information is abnormal, an environmental warning message is generated; When the number of environmental anomalies exceeds the preset value, an environmental warning message is generated.

[0056] The process of collecting environmental wind force information is as follows: wind force collection equipment is set up in the east, west, south and north directions of the photovoltaic cell; When the ambient temperature information is greater than the preset value, and the wind force information collected by the wind force collection devices set in the four directions of east, west, south and north are all less than the preset value, it means that the ambient wind force information is abnormal; The process of obtaining the number of environmental anomalies is as follows: extract the center position of the photovoltaic power generation equipment, use the position as the reference point, draw a circle with a preset length as the radius, obtain the detection area, collect the number of objects with a height greater than the preset height in the detection area, and obtain the number of environmental anomalies; The above process realizes active defense against hot spot effect and joint warning of high temperature + no wind. When the ambient temperature is greater than the preset value and the wind speed in all four directions is less than the threshold, the warning is triggered, preventing the hot spot effect caused by poor heat dissipation of photovoltaic panels in advance, that is, preventing local high temperature from damaging the battery cells.

[0057] Directly judge the air flow around the solar panels through wind force detection to ensure that the heat dissipation effect meets the standards; Wind speed data is collected synchronously in four directions: east, west, south, and north, to avoid misjudgment caused by obstruction in a single direction; Dynamic heat dissipation verification: Combined with wind data under high temperature conditions, the effectiveness of the heat dissipation system can be verified in real time; Early identification of occlusion risks and quantitative detection of obstacles: a circular area is defined based on the center of the photovoltaic panel, and the number of tall objects (such as trees and buildings) is automatically counted to detect occlusion risks in advance; Predictive maintenance of power generation efficiency: reduce power generation loss caused by obstruction through early warning of abnormal objects; Comprehensive environmental risk assessment: Integrate temperature, wind speed, and obstacle data to build a multi-dimensional environmental risk model; High temperature + no wind dual trigger conditions improve the reliability of warnings and avoid false alarms of single parameters; Identify windless environments through wind monitoring and prevent equipment from overheating and damage through high temperature warnings; Anomaly warning helps adjust equipment layout and reduce mechanical stress caused by obstacles during strong winds; This enables early positioning of areas with poor heat dissipation and obstacles, and optimizes cleaning / maintenance routes; The four-way wind speed sensor monitors the air flow speed around the solar panel in real time. When the wind speed is insufficient in a high temperature environment, the system can immediately determine that the heat dissipation conditions have deteriorated and trigger an early warning. This design is directly related to the thermal management requirements of the photovoltaic panel. By quantifying the air flow parameters, the heat dissipation efficiency is guaranteed to avoid the reduction of power generation efficiency and shortened equipment life due to poor heat dissipation.
