Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation protection, and in particular to a photovoltaic power generation equipment protection method and system. Background Art

[0002] With the global energy restructuring and the rapid development of renewable energy, photovoltaic power generation equipment is increasingly being used in high-altitude, cold regions. These regions typically feature strong solar radiation and long hours of sunshine, which are favorable for photovoltaic power generation. However, they also face extreme environmental challenges such as low temperatures, strong ultraviolet rays, strong winds, and ice and snow. The protection technology for photovoltaic power generation equipment in these high-altitude, cold regions has evolved from simple adaptive modifications to specialized, intelligent protection. Initially, basic protective measures such as heating devices and reinforced brackets were primarily employed. Subsequently, targeted technologies such as intelligent snow removal, freeze-thaw monitoring, and UV-resistant coatings were gradually developed. These technologies also integrate environmental monitoring, fault diagnosis, and remote control functions, forming a comprehensive, multi-dimensional protection system.

[0003] Currently, a relatively mature system has been established for the protection of photovoltaic power generation equipment in high-altitude and cold regions. This system primarily encompasses the following aspects: First, low-temperature protection, such as the use of heating films and thermal circulation systems to ensure the normal operation of equipment in extremely cold environments; second, structural protection, including reinforced supports and snow-proof designs to cope with strong winds and snow loads; third, material protection, such as the use of special materials that are UV-resistant and cryogenically resistant; Furthermore, specialized equipment such as intelligent snow removal systems, lightning protection, and plateau inverters are also included. At the system level, remote monitoring and intelligent operation and maintenance systems are widely used to enable real-time monitoring and rapid response to equipment operating status and environmental parameters. The application of these technologies has significantly improved the safety, reliability, and power generation efficiency of photovoltaic power generation equipment in high-altitude and cold regions.

[0004] However, existing technologies for protecting photovoltaic power generation equipment in high-altitude and cold regions still have some shortcomings. In existing technologies, when protecting photovoltaic power generation equipment, protective devices are typically used to achieve the protective function. While this method can achieve effective protection, in actual operation, the protective devices can easily affect the power generation performance of the photovoltaic power generation equipment due to the continuous protection. Summary of the Invention

[0057] The present invention provides a photovoltaic power generation equipment protection method and system.

[0058] See also Figures 1 to 6 For ease of understanding, a method for protecting photovoltaic power generation equipment is provided. The photovoltaic power generation equipment includes a bracket 100 and a photovoltaic solar panel 200 installed on top of the bracket 100. A pressure sensor 300 is installed between the connection position of the bracket 100 and the photovoltaic solar panel 200.

[0059] The photovoltaic power generation equipment protection method comprises the following steps:

[0060] S100: Utilize the pressure sensor to collect real-time pressure data transmitted by the photovoltaic solar panel.

[0061] In this step, the real-time pressure data from the example accurately reflects the external pressure on the photovoltaic solar panel, providing a basis for subsequent judgment. The pressure sensor installed between the bracket and the photovoltaic solar panel has high accuracy and stability, suitable for long-term monitoring.

[0062] S200. Obtain a real-time ratio of real-time pressure data to initial pressure data; wherein the initial pressure data is the initial pressure transmitted by the photovoltaic solar panel when the photovoltaic power generation equipment is completed and accepted.

[0063] In this step, the real-time ratio reflects the current pressure changes experienced by the equipment and allows for the timely detection of abnormalities during operation. Initial pressure data is collected during the final acceptance inspection of the equipment, ensuring the accuracy and validity of the reference value.

[0064] S300, setting a preset ratio interval; wherein the preset ratio interval includes a first ratio interval and a second ratio interval, the initial pressure data is A, the first ratio interval is B, A<B≤1.01A; the second ratio interval is C, C>1.01A.

[0065] In this step, the setting of the preset ratio interval is based on a large amount of experimental data, which can effectively distinguish between normal and abnormal states and has strong adaptability and scalability.

[0066] It can be further clarified that, in this embodiment, after the photovoltaic power generation system is installed outdoors in a high-altitude and cold area, when it is in working condition, the source of the pressure data that affects the photovoltaic solar panel transmitted to the sensor is usually due to the accumulation formed on the surface of the photovoltaic solar panel, which causes the weight of the photovoltaic solar panel to increase. Under outdoor conditions, there are two main reasons for the formation of accumulation on the surface of the photovoltaic solar panel, one is ice or snowfall, and the other is dust accumulation. The increase in the gravity of photovoltaic solar energy caused by dust accumulation and environmental freezing is limited, while the ice caused by precipitation freezing or snowfall is not. Therefore, in this embodiment, the first ratio interval and the second ratio interval are set respectively, which is to provide operating specifications for subsequent protective operations and improve protection efficiency.

[0067] The primary reason for choosing 1.01A as the endpoint is to ensure that photovoltaic solar systems can maintain stability and safety despite minor environmental fluctuations in high-altitude cold regions. The reason for choosing 1.01A as the intermediate threshold is based on the following considerations: In high-altitude cold regions, the temperature swings between day and night are significant, and slight temperature fluctuations can cause thermal expansion and contraction of materials. Setting the endpoint at 1.01A allows the system to remain stable under these relatively small strains, preventing structural deformation or damage from minor load changes. Wind speeds in high-altitude cold regions can fluctuate frequently, and small adjustments in wind speed can cause slight increases in pressure. By allowing for a 1% pressure fluctuation, the system can absorb these frequent minor shocks without compromising overall stability. From a structural mechanics and engineering design perspective, a certain amount of redundancy is typically provided to ensure safety. This 1% margin provides an additional safety margin for the system, consistent with common design codes and standard practices, ensuring sufficient load capacity in the event of an emergency. The 1.01x setting provides a basic safety buffer, ensuring the durability and stability of the overall system. Based on historical data analysis of pressure fluctuations in similar environments, a 1% fluctuation is considered relatively safe under most non-extreme conditions. Therefore, this setting can effectively improve system reliability. In standard designs and best practices across multiple fields, a small amount of design redundancy beyond the normal operating range is considered a generally accepted design approach to ensure flexible handling capabilities under various operating conditions.

[0068] The choice of 1.01A as the endpoint of the ratio range was based on a multifaceted approach, taking into account the unique environmental factors of high-altitude cold regions and the safety and stability requirements of structural design. This approach allows the photovoltaic solar system to better adapt to changes in its operating environment, maintaining its functionality and safety with minor adjustments.

[0069] S400: Determine whether the real-time ratio is within the preset ratio range.

[0070] In this step, when the real-time ratio is lower or higher than the preset range, the system will trigger an alarm or prompt to guide relevant personnel to take appropriate measures.

[0071] S500: When the real-time ratio is within the preset ratio range, executing a preset protection strategy.

[0072] In step S500, when the real-time ratio is within the preset ratio range, the preset protection strategy is executed. The installation angle can be adjusted or a temporary support device can be activated to ensure the long-term operation of the protection device and the stability of the photovoltaic system.

[0073] Through the above steps, the photovoltaic power generation equipment protection method of the present invention can significantly reduce the impact of protective equipment on photovoltaic power generation efficiency, ensuring the stability and durability of the equipment. Compared with traditional protection methods, this method utilizes pressure sensors to continuously collect data, ensuring the real-time validity of information. It also utilizes ratio-based zoning to protect equipment, improving the accuracy of technical judgment. Different strategies can be implemented according to specific circumstances to reduce interference and impact on the equipment.

[0074] To better understand the present invention, the overall inventive concept of the present invention is as follows: using a sensor installed at the connection between a photovoltaic solar panel of a photovoltaic power generation device and a bracket supporting the photovoltaic solar panel, real-time pressure data of the photovoltaic solar panel is collected in real time, and a real-time ratio of the real-time pressure data to the initial pressure data collected when the photovoltaic solar panel is just installed is obtained. At the same time, a preset ratio range is set, which includes a first ratio range (0-1%) and a second ratio range (greater than 1%). Then, it is determined whether the real-time ratio is within the first ratio range or the second ratio range. When the real-time ratio is within the first ratio range, the ambient humidity and ambient temperature are collected in real time. When the ambient temperature is greater than 0°C and the ambient humidity is less than 80%, it is determined that the source of the pressure increase transmitted to the sensor by the photovoltaic solar panel is dust or sand. At this time, a pre-set cleaning device is used to clean the photovoltaic solar panel. After the cleaning operation is completed and the corresponding photovoltaic solar panel is dried for a preset period of time, the first current pressure data of the sensor is obtained again. When the ratio of the first current pressure data of the photovoltaic solar panel to the preset pressure value is not within the first ratio range or the second ratio range, the cleaning protection operation is completed. When the real-time ratio is in the first ratio interval, the ambient humidity and ambient temperature are collected in real time; when the ambient temperature is less than 0°C and the ambient humidity is greater than 80%, it is determined that the source of the pressure increase value transmitted to the sensor by the photovoltaic solar panel is ice caused by high humidity moisture in the air. At this time, the de-icing equipment pre-installed on the photovoltaic solar panel is used to heat and de-ice the photovoltaic solar panel. After completing the de-icing operation and keeping the corresponding photovoltaic solar panel warm for a preset period of time, the second current pressure data of the sensor is obtained. When the ratio of the second current pressure data of the photovoltaic solar panel to the preset pressure value is not within the first ratio interval and the second ratio interval, the de-icing protection operation is completed. When the real-time ratio is within the second ratio interval, it is determined that the source of the pressure increase value transmitted to the sensor by the photovoltaic solar panel is snowfall or precipitation ice. At this time, the de-icing equipment pre-installed on the photovoltaic solar panel is used to heat and de-ice the photovoltaic solar panel. After the de-icing operation is completed and the corresponding photovoltaic solar panel is kept warm for a preset period of time, the third current pressure data of the sensor is obtained. When the ratio of the third current pressure data of the photovoltaic solar panel to the preset pressure value is not within the first ratio interval and the second ratio interval, the de-icing protection operation is completed.

[0075] In this embodiment, a pressure sensor is used to collect real-time pressure data transmitted by the photovoltaic solar panel in real time, obtain a real-time ratio of the real-time pressure data to the initial pressure data, set a preset ratio interval, and determine whether the real-time ratio is within the preset ratio interval. When the real-time ratio is within the preset ratio interval, the preset protection strategy is selected for execution, so that the present invention can determine whether it is necessary to perform protection operations on the photovoltaic power generation equipment based on the ratio between the real-time pressure data transmitted to the sensor by the photovoltaic solar panel and the preset pressure data, and thus there is no need to continuously protect the photovoltaic power generation equipment, thereby avoiding the power loss caused by the continuous or permanent protection equipment that is set to continuously protect the photovoltaic power generation equipment and the defect that the power generation efficiency of the photovoltaic power generation equipment is affected due to the continuous protection of the protection equipment, thereby effectively ensuring the power generation efficiency of the photovoltaic power generation equipment.

[0076] In one embodiment, a cleaning device is installed on the periphery of the photovoltaic solar panel, the cleaning device is arranged toward the photovoltaic solar panel, and the cleaning device includes a cleaning mode.

[0077] Specifically, the cleaning equipment's configuration enables photovoltaic solar panels to maintain optimal operating conditions under various environmental conditions, reducing the decline in photovoltaic conversion efficiency caused by dust accumulation. The present invention primarily involves the intelligent control of the cleaning equipment, addressing the high energy consumption and low efficiency of traditional cleaning equipment.

[0078] Step S500 includes:

[0079] S510: When the real-time ratio is within the first ratio interval, real-time ambient temperature and real-time humidity of the area where the photovoltaic power generation equipment is located are collected in real time.

[0080] In step S510, when the real-time ratio is within the first ratio range, the system collects the ambient temperature and humidity of the area where the photovoltaic power generation equipment is located in real time. The environmental data obtained by the high-precision sensor can support accurate decision-making for subsequent cleaning operations.

[0081] S520: Determine whether the real-time ambient temperature is greater than 0° C. and whether the real-time ambient humidity is less than 80%.

[0082] In step S520, setting the judgment conditions can ensure that the cleaning operation is performed under suitable environmental conditions, thereby improving cleaning efficiency and avoiding waste of resources.

[0083] S530: When the real-time ambient temperature is greater than 0°C and the real-time ambient humidity is less than 80%, the protective device is started and the protective device is made to execute the cleaning mode to clean the photovoltaic solar panel, thereby completing the execution of the protection strategy.

[0084] Through step S530, not only the light transmittance of the photovoltaic panel is improved, but also the long-term damage to the equipment caused by pollutants can be effectively prevented, and the goal of maintaining high power generation efficiency is ultimately achieved.

[0085] Through the above steps, the protection method of the present invention optimizes photovoltaic power generation efficiency and solves the problems of difficult and inefficient regular equipment maintenance. Compared with traditional manual cleaning methods, it has the advantages of taking appropriate cleaning measures for different environmental conditions, reducing manual intervention and lowering operation and maintenance costs, and maintaining the cleanliness of the photovoltaic panel surface, thereby improving long-term energy output efficiency.

[0086] In one embodiment, step S530 includes:

[0087] S531. When the real-time ambient temperature is greater than 0° C. and the real-time ambient humidity is less than 80%, the protective device is started and the protective device is made to execute the cleaning mode to clean the photovoltaic solar panel.

[0088] In step S531, environmental conditions are set to ensure rapid evaporation of moisture, preventing water stains that could impact solar panel performance. This also prevents ice formation caused by high humidity, improving dust removal efficiency. Real-time environmental monitoring and control allows for optimal cleaning, effectively improving the conversion efficiency of photovoltaic equipment.

[0089] S532: After the cleaning operation is completed and the photovoltaic solar panel is dried for a preset period of time, the first current pressure data transmitted from the photovoltaic solar panel to the pressure sensor is collected again.

[0090] In step S532 , pressure data collection can further verify the cleaning effect to ensure the stability and connectivity of the solar panel after cleaning.

[0091] S533: When the first current pressure data is not within the preset pressure range, the cleaning and protection operation of the photovoltaic power generation equipment is completed.

[0092] In step S533, not only is the cleaning effect verified, but it is also possible to promptly identify whether there is any potential physical damage to the equipment.

[0093] Through the above steps, the photovoltaic power generation equipment protection method of the present invention realizes intelligent cleaning and monitoring operations, and successfully solves the technical problem that may cause efficiency reduction during equipment cleaning and maintenance.

[0094] In one embodiment, the protection device further includes a de-icing mode, and the protection device is switchable between the cleaning mode and the de-icing mode.

[0095] In the described embodiment, the protective device is installed around the perimeter of the photovoltaic solar panel and has two operating modes: cleaning mode and de-icing mode. By switching between these modes, the protective device can perform corresponding protective operations under different environmental conditions, ensuring that the solar panel maintains optimal working condition, effectively addressing the problem of reduced power generation efficiency caused by dirt and ice on the photovoltaic panel surface.

[0096] After step S520, the method further includes:

[0097] S540: When the real-time ambient temperature is less than 0° C. and the real-time ambient humidity is greater than 80%, the protective device is activated and enabled to execute the deicing mode to heat and de-ice the photovoltaic solar panel.

[0098] Specifically, in step S540, the de-icing mode aims to heat the surface of the solar panel to quickly melt the ice and snow attached to it, thereby avoiding the adverse effects of ice accumulation on the photovoltaic panel. This step is determined by the temperature sensing device and the humidity sensing device in a coordinated manner to ensure that the de-icing operation is carried out under safe and effective conditions.

[0099] S550: After the deicing operation is completed, control the protective device to continue to execute the deicing mode and keep the photovoltaic solar panel warm for a first preset time period.

[0100] Step S550 is to perform a heat preservation treatment on the photovoltaic solar panel after the de-icing operation is completed. At this time, the protective device control system still maintains the de-icing mode and continues to warm the panel surface for a preset period of time.

[0101] In one embodiment, after step S550, the method further includes:

[0102] S560: Collect the second current pressure data transmitted from the photovoltaic solar panel to the pressure sensor again.

[0103] In this embodiment, the protective device for photovoltaic power generation equipment not only has a cleaning function but also a de-icing mode. To cope with low-temperature icing conditions, the system can switch between de-icing and cleaning according to environmental changes, ensuring that the surface of the photovoltaic panels remains clean, thereby achieving normal photovoltaic conversion efficiency.

[0104] Specifically, in step S560, after the photovoltaic panel insulation process is completed, the second current pressure data transmitted by the photovoltaic solar panel to the pressure sensor is collected again. This allows for continuous monitoring of the physical condition of the solar panel, ensuring that the de-icing process does not cause excessive pressure on the panel structure and preventing material stress problems caused by temperature differences.

[0105] S570: When the second current pressure data is not within the preset pressure range, complete the de-icing protection operation for the photovoltaic power generation equipment.

[0106] In step S570, if the second current pressure data is not within the preset safe pressure range, it indicates that the equipment may be in an abnormal state after deicing. At this point, the system confirms the completion of the deicing protection operation for the photovoltaic equipment and prompts further inspection or maintenance to ensure the long-term stable operation of the equipment.

[0107] In one embodiment, step S500 further includes:

[0108] S51. When the real-time ratio is within the second ratio interval, it is determined that the source of the pressure increase value transmitted by the photovoltaic solar panel to the sensor is snowfall or precipitation freezing.

[0109] In step S51, this judgment can help the system accurately distinguish the physical pressure changes caused by different environmental factors, thereby optimizing the protection strategy and improving the working efficiency of the solar panel.

[0110] S52: Start the protective device and enable the protective device to execute the deicing mode to heat and de-ice the photovoltaic solar panel.

[0111] In step S52, the system activates the protective device to execute de-icing mode. During this operation, the device heats the solar panels to remove surface obstructions caused by snow or ice. This heating and de-icing process not only eliminates the reduction in solar efficiency caused by snow and ice accumulation, but also prevents structural damage to the panels caused by long-term freezing, thereby extending the panel's service life.

[0112] S53: After the deicing operation is completed, control the protective device to continue to execute the deicing mode and keep the photovoltaic solar panel warm for a second preset time period.

[0113] In step S53, after the de-icing operation is complete, the protective device continues de-icing mode, maintaining the temperature of the photovoltaic panels for a predetermined period of time. This heat preservation process, as exemplified in step S53, prevents the panels from refreezing within a short period of time, ensuring the long-term effectiveness of the de-icing process while minimizing energy loss.

[0114] Through this series of steps, the photovoltaic power generation equipment protection method of the present invention achieves automated deicing and protection in adverse weather conditions, mitigating the impact of snowfall or ice on equipment power generation efficiency. Unlike traditional physical deicing or fixed-period heating systems, this method distinguishes between changes in panel pressure caused by snowfall and ice formation, enabling precise protection strategies. It also eliminates the need for manual intervention, reducing operational and maintenance burdens and costs.

[0115] In one embodiment, after step S53, the method further includes:

[0116] S54: again collecting the third current pressure data transmitted by the photovoltaic solar panel to the pressure sensor.

[0117] In step S54, it is possible to monitor whether there are any pressure changes on the panel surface due to incomplete de-icing or re-icing during the extended insulation period. Compared with the previous two data collection and judgments, this step further confirms the continued effectiveness of the protection operation.

[0118] S55: When the third current pressure data is not within the preset pressure range, completing the de-icing protection operation for the photovoltaic power generation equipment.

[0119] In step S55, if the third current pressure data is outside the preset safety pressure range, the system determines that the PV system's de-icing protection operation has been completed. More specifically, by analyzing the pressure data, the system can automatically detect when the panels have returned to normal and prompt the system to terminate the protection operation, thereby avoiding unnecessary energy consumption and excessive operation, and protecting the longevity of the equipment.

[0120] This method, through multiple monitoring and evaluation mechanisms, achieves efficient and intelligent de-icing and protection for photovoltaic equipment, resolving equipment performance issues caused by low-temperature icing. Furthermore, the invention offers advantages such as ensuring the accuracy and effectiveness of protection through multiple pressure data collection and analysis; accurately terminating the operation upon completion of protection, reducing unnecessary energy consumption; and preventing potential damage to photovoltaic panels due to refreezing through continuous monitoring.

[0121] In one embodiment, after step S400, the method further includes:

[0122] S600: When the real-time ratio is not within the preset ratio range, the protection strategy is not executed and the photovoltaic power generation equipment is controlled to perform photovoltaic power generation operation.

[0123] Specifically, in step S600, if the real-time ratio is outside the preset range, the control system will not perform additional protective measures and will instead allow the PV equipment to continue normal PV power generation operations. This step, based on the system's current external environment and equipment performance, achieves efficient energy and resource utilization by ignoring unnecessary protective actions.

[0124] Through monitoring, the equipment can maintain continuous power output while reducing unnecessary energy consumption. This avoids the activation of redundant protection modes when there are no environmental threats, thereby improving the overall efficiency of the photovoltaic system. It also reduces equipment operational complexity and maintenance costs.

[0125] This method has the advantages of real-time monitoring of ratio data to ensure the accuracy of protection decisions; avoiding energy consumption caused by excessive protection and improving photoelectric conversion efficiency; reducing unnecessary equipment operations and lowering the system maintenance burden.

[0126] Based on the same technical concept, in a second aspect, the present invention further proposes a protection system for photovoltaic power generation equipment, wherein the photovoltaic power generation equipment includes a bracket 100 and a photovoltaic solar panel 200 mounted on top of the bracket 100. The protection system includes:

[0127] The sensor 300 is installed at the connection between the photovoltaic solar panel 200 and the bracket 100;

[0128] A protective device 400 , wherein the protective device 400 is installed on the periphery of the photovoltaic solar panel 200 and is disposed toward the surface of the photovoltaic solar panel 200 ; and

[0129] The terminal 500 is communicatively connected to the sensor 300 and the protection device 400 respectively, and the terminal 500 is used to execute the photovoltaic power generation equipment protection method described in the first aspect.

[0130] First, a sensor 300 is installed at the junction of the photovoltaic solar panel 200 and the bracket 100. The sensor 300 monitors the environmental parameters and physical conditions of the junction in real time, ensuring that the photovoltaic system can obtain timely data and respond effectively under both normal and abnormal operating conditions. In one specific embodiment, the sensor 300 is a high-precision pressure sensor capable of detecting structural stress fluctuations caused by wind speed changes or ice and snow accumulation. This real-time data is transmitted to the terminal 500, providing a basis for subsequent adjustments to the protective equipment 400.

[0131] Protective device 400 is installed around the periphery of photovoltaic solar panel 200, facing the panel surface. Its primary function is to dynamically adjust the protective state based on data from sensor 300 to minimize the impact of protection on power generation efficiency. In one embodiment, protective device 400 may utilize a smart dimming film material that adjusts its transmittance based on changes in light intensity, ensuring protection without significantly reducing power generation efficiency due to light blocking.

[0132] In another embodiment, the protective device 400 is designed to have an external baffle with automatically adjustable angle. After the sensor 300 senses real-time environmental data, it adjusts the baffle angle through the terminal 500 instruction, so that it automatically changes the protective posture in strong light or blizzard conditions, thereby avoiding unnecessary obstruction and improving the power generation effect.

[0133] Terminal 500, serving as the system's control unit, is communicatively connected to the sensor 300 and protective device 400. It is used to execute the photovoltaic power generation equipment protection method described in the first aspect. In one specific embodiment, terminal 500 integrates advanced data processing and artificial intelligence algorithms to analyze and predict potential environmental changes or risks in real time based on data received from sensor 300, and then automatically adjust the operating state of protective device 400.

[0134] In yet another embodiment, the terminal 500 is configured to have a remote management function, which enables continuous monitoring and adjustment of the device through a network interface, ensuring immediate response and optimization of protection strategies under any conditions.

[0135] By synergizing these components, the photovoltaic power generation equipment protection system of the present invention successfully resolves the technical issue of protective device 400 impacting power generation performance. The system continuously monitors environmental changes and dynamically adjusts the parameters of protective device 400, ensuring adequate protection while minimizing impact on the performance of the photovoltaic panels. Compared to traditional protection systems lacking intelligent adjustment capabilities, the present invention maximizes power generation efficiency while ensuring equipment safety, conserving resources, and improving the overall effectiveness of the equipment.

[0136] In one embodiment, the protection system further includes a temperature and humidity acquisition device 600 , which is spaced apart from the photovoltaic power generation equipment in the area where the photovoltaic power generation equipment is located, and the temperature and humidity acquisition device 600 is communicatively connected to the terminal 500 .

[0137] Temperature and humidity collection devices 600 are installed and distributed in localized areas of the photovoltaic system to comprehensively collect environmental parameters for the entire area. In one embodiment, these devices accurately measure the temperature and humidity around the solar panels. By acquiring real-time local weather data, it is possible to predict the impact of potential factors such as condensation or ice and snow accumulation on panel efficiency.

[0138] In another embodiment, the temperature and humidity sensors 300 and 301 are integrated into multiple data acquisition modules. The spaced distribution of these modules enhances the ability to monitor the entire photovoltaic system on-site. This architecture improves the system's ability to respond to microclimate changes in the region and facilitates fine-tuning of protection strategies.

[0139] The temperature and humidity collection device 600 communicates with the terminal 500 via a wireless network or a wired connection. The terminal 500 dynamically adjusts the operating state of the protection system based on the collected data to ensure that the photovoltaic system can operate effectively under various environmental conditions.

[0140] Of course, terminal 500 can control the opening and closing of protective device 400 based on temperature and humidity data. For example, when humidity is too high, it can automatically activate the protective film to prevent condensation. Terminal 500 can also use intelligent algorithms to predict possible high-risk conditions in conjunction with sensor 300 data, thereby implementing corresponding preventative measures in advance, such as actively heating the protective layer to prevent ice formation.

[0141] Through the integration and rational layout of the temperature and humidity acquisition device 600, the present invention excels in addressing the problem of insufficient environmental monitoring. The system can effectively provide information about the microclimate of the area where the photovoltaic equipment is located and use this information to adjust protection strategies in real time. Through the coordinated operation of the terminal 500 and the sensor 300, photovoltaic power generation equipment can be optimized and protected in all weather conditions, reducing the risk of performance loss or equipment damage caused by environmental changes. Compared with traditional passive protection systems, this embodiment improves the overall performance of photovoltaic equipment and brings significant long-term stability and high efficiency.

Any equivalent structural transformation made by utilizing the contents of the present invention's description and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
