Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, and in particular to a flexible, semi-transparent photovoltaic greenhouse system capable of generating electricity. Background Technology

[0002] Photovoltaic greenhouses are a product of the integration of photovoltaic power generation and modern agriculture. They integrate solar photovoltaic power generation systems, intelligent temperature control systems, and modern high-tech planting techniques, offering numerous significant benefits. In terms of economic benefits, the photovoltaic panels installed on the roof of the greenhouse convert solar energy into electricity, meeting the power needs of lighting, irrigation, temperature control, and other equipment within the greenhouse, achieving self-sufficiency in electricity and reducing the electricity costs of agricultural production. Regarding optimized planting, the intelligent temperature control system of photovoltaic greenhouses can precisely control environmental parameters such as temperature, humidity, and light within the greenhouse, creating optimal conditions for crop growth, thereby improving crop yield and quality. In terms of land utilization, photovoltaic greenhouses achieve a dual-use model of "power generation on the panels, planting underneath," making three-dimensional use of land resources without occupying additional land, significantly increasing the economic output of the land. Therefore, the integration of the photovoltaic industry and agriculture is undoubtedly an important direction for the future development of intelligent agriculture.

[0003] Photovoltaic products, as an environmentally friendly product, have created enormous wealth through their integration with agriculture. Currently, the main photovoltaic product is crystalline silicon solar cells, while perovskite solar cells, as a rising star, have shown many advantages. Their principle is based on the photovoltaic effect. When sunlight shines on the perovskite layer of a perovskite solar cell, the perovskite material absorbs photon energy and generates excitons. Due to the low exciton binding energy of the perovskite material, these excitons rapidly separate into free electrons and free holes at room temperature. The separated free electrons and holes then transport within the perovskite material. The electrons and holes transported through the transport layer are collected by electrodes, forming current and voltage. A typical perovskite solar cell structure mainly consists of a transparent conductive substrate, a carrier transport layer (including an electron transport layer and a hole transport layer), a perovskite layer, and metal electrodes. These layers are stacked together and work together to complete the photoelectric conversion process. Flexible perovskite solar cells are perovskite solar cells fabricated on flexible substrates (such as polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polyimide (PI), etc.). Semi-transparent perovskite solar cells (ST-PSCs) represent a cutting-edge technology in the photovoltaic field, achieving both power generation and light transmission through material innovation and structural optimization. Due to their light transmission, lightweight, and flexibility, semi-transparent flexible perovskite solar cells are ideally suited for integration into smart agriculture.

[0004] In existing technologies, image acquisition devices are used to capture images of photovoltaic panels and transmit them to data processing modules for image processing to determine whether the photovoltaic panels are damaged and where the damage is located. However, the repair of photovoltaic panels often relies solely on personal experience, resulting in a low success rate and waste of photovoltaic panels. Replacing damaged photovoltaic panels also increases farmers' production costs. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology in terms of the low success rate of repairing damaged photovoltaic panels, and to provide a flexible, semi-transparent photovoltaic greenhouse system that can generate electricity.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A flexible, semi-transparent photovoltaic greenhouse system capable of generating electricity includes photovoltaic panels composed of flexible, semi-transparent perovskite solar cell modules and an AI data processing module. The photovoltaic panels are laid on the roof of the greenhouse, and a roller module is installed on the roof of the greenhouse. One end of the photovoltaic panel is fixed to the roller module, and an inspection module is installed on the roller module. The AI ​​data processing module is electrically connected to both the roller module and the inspection module.

[0008] Preferably, the flexible semi-transparent perovskite solar cell module includes a transparent waterproof layer, a flexible semi-transparent perovskite solar cell layer, and a transparent heat insulation layer that are sequentially bonded together.

[0009] Preferably, the reel module includes a reel and an electronic controller, one end of which is mechanically connected to the reel and the other end of which is electrically connected to the AI ​​data processing module.

[0010] Preferably, the electronic controller is an electric motor, one end of which is mechanically connected to the reel, and the other end is electrically connected to the AI ​​data processing module.

[0011] Preferably, the reel includes a shaft and a housing sleeved outside the shaft, the housing being fixed to the shaft.

[0012] Preferably, a cleaning brush is installed on the shaft housing for cleaning the photovoltaic panel when the reel rotates.

[0013] Preferably, the inspection module is a high-definition camera or a spectral camera.

[0014] Preferably, it also includes an environmental sensing module, which is installed inside the greenhouse and electrically connected to the AI ​​data processing module.

[0015] Preferably, the environmental sensing module includes a temperature sensor, a humidity sensor, a light intensity sensor, and a carbon dioxide concentration sensor, wherein the temperature sensor, the humidity sensor, the light intensity sensor, and the carbon dioxide concentration sensor are electrically connected to the AI ​​data processing module.

[0016] Preferably, it further includes a power output module for outputting the power generated by the photovoltaic panel to an external electrical device. The positive input terminal of the power output module is electrically connected to the positive terminal of the photovoltaic panel, the negative input terminal is electrically connected to the negative terminal of the photovoltaic panel, and the output terminal of the power output module is electrically connected to the external electrical device.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention involves laying photovoltaic panels composed of flexible, semi-transparent perovskite solar cell modules on the roof of a greenhouse. A roll-up module is installed on the roof, with one end of the photovoltaic panel fixed to the roll-up module. An inspection module is installed on the roll-up module, and an AI data processing module is electrically connected to both the roll-up module and the inspection module. When the roll-up module rolls up the photovoltaic panel, the inspection module captures an image of the photovoltaic panel's surface and transmits it to the AI ​​data processing module. The AI ​​data processing module determines whether the photovoltaic panel is damaged, identifies the location and type of damage, and provides a repair method. This information is then transmitted to an external display device for viewing by relevant personnel. This improves the repair success rate of damaged photovoltaic panels and reduces the replacement rate, thereby lowering farmers' production costs. Furthermore, the AI ​​data processing module provides farmers with real-time updates on the health of the photovoltaic panels, allowing for timely repairs and preventing further damage due to data transmission delays, further reducing farmers' maintenance costs.

Detailed Implementation

[0027] The present invention will be further described in detail below with reference to experimental examples and specific embodiments. However, this should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0028] like Figure 1As shown, a flexible, semi-transparent photovoltaic greenhouse system capable of generating electricity includes a photovoltaic panel 10 composed of flexible, semi-transparent perovskite solar cell modules and an AI data processing module 20. The photovoltaic panel 10 is laid on the roof of the greenhouse, and a roller module 30 is installed on the roof of the greenhouse. One end of the photovoltaic panel 10 is fixed to the roller module 30, and an inspection module 40 is installed on the roller module 30. The AI ​​data processing module 20 is electrically connected to both the roller module 30 and the inspection module 40. The flexible perovskite solar cell modules are used directly as the photovoltaic panel 10, which can meet the folding, bending, and even stretching requirements of the photovoltaic panel 10 during use, increasing its application flexibility. In use, the photovoltaic panel 10 composed of flexible, semi-transparent perovskite solar cell modules fully absorbs solar energy and completes photoelectric conversion in a sunny environment. The AI ​​data processing module 20 can be installed inside or outside the greenhouse. It includes an edge computing control unit, which deploys a YOLOv8n model, a Mobile-UNet model, and an embedded relational database (SQLite). The YOLOv8n model identifies whether the photovoltaic panel 10 is damaged and the type of damage. The Mobile-UNet model determines the location of the damage. The embedded relational database stores common methods for repairing the photovoltaic panel 10. When the image of the photovoltaic panel 10 collected by the inspection module 40 is transmitted to the YOLOv8n model, if the YOLOv8n model determines that there is damage and its type, it transmits the damage information to the Mobile-UNet model to determine the location of the damage. The damage type is then matched with the SQLite database to determine the repair method. The method involves connecting the AI ​​data processing module 20 to an external display device when it is necessary to display the damage type, location, and repair method. This data is transmitted to the external display device for viewing by relevant personnel. Based on the location information, personnel locate the damaged photovoltaic panel 10 and repair it according to the provided repair method. This improves the repair success rate of the damaged photovoltaic panel 10 and reduces its replacement rate, thereby lowering farmers' production costs. Simultaneously, the AI ​​data processing module 20 provides farmers with real-time information on the health status of the photovoltaic panel 10, allowing for timely repairs and preventing further damage due to data transmission delays, further reducing maintenance costs. Since the photovoltaic panels 10 installed in greenhouses are composed of numerous sub-panels, when replacement is needed, the corresponding damaged sub-panel is located and disassembled, and a sub-panel of the same specifications is installed in the same location for replacement.The specific model of the edge computing main control unit is Jetson Xavier NX. The inspection module 40 is a high-definition camera or a spectrometer camera, which observes the damage of the photovoltaic panel 10 in real time during the daily installation and removal of the photovoltaic panel 10, and identifies damage such as cracks, scratches or delamination. The specific model of the high-definition camera is Sony IMX477, and the specific model of the spectrometer camera is SpecimIQ.

[0029] In some embodiments, such as Figure 2 As shown, the flexible semi-transparent perovskite solar cell module includes a transparent waterproof layer 11, a flexible semi-transparent perovskite solar cell layer 12, and a transparent heat insulation layer 13 that are sequentially bonded together. The transparent waterproof layer 11 can be made of polyethylene (PE), polyvinyl chloride (PVC), or ethylene-vinyl acetate copolymer (EVA). It not only meets the light transmittance required for crop growth but also provides a stable and suitable growing environment for crops, preventing them from being damaged by floods. Its thickness ranges from 0.1 to 0.2 mm. The flexible semi-transparent perovskite solar cell layer 12 can be stretched freely to meet any expansion and contraction conditions. It is used to regulate temperature imbalances in greenhouses, avoid strong light inhibition, promote crop growth, and provide fresh air for crops. As a means of artificially regulating crop respiration, it improves the quality of agricultural products. Its thickness ranges from 0.05 to 0.15 mm. The transparent heat-insulating layer 13 is made of polycarbonate (PC), ethylene-vinyl acetate (EVA) multifunctional composite film, or polyolefin multifunctional plastic film. It meets the needs of a stable growing environment for crops and artificially controls the crop growth rate. Its thickness ranges from 0.2 to 0.4 mm.

[0030] like Figure 3 As shown, in some embodiments, the reel module 30 includes a reel 31 and an electronic controller 32. One end of the electronic controller 32 is mechanically connected to the reel 31, and the other end is electrically connected to the AI ​​data processing module 20. After receiving a signal, the AI ​​data processing module 20 controls the electronic controller 32 to reel in and out of the reel 31. The electronic controller 32 is preferably an electric motor. One end of the electric motor is mechanically connected to the reel 31, and the other end is electrically connected to the AI ​​data processing module 20. The electric motor is preferably a 24V DC geared motor with a power range of 100W to 300W to control the rotational speed of the reel 31 between 20rpm and 90rpm. The reel 31 includes a shaft 311 and a housing 312 sleeved on the outside of the shaft 311. The housing 312 is fixed to the shaft 311 by bolts. The housing 312 is made of stainless steel to protect the photovoltaic panel 10 from external damage when rolled up. The diameter of the shaft 311 is preferably 50-100mm. The length of the housing is the same as the width of the greenhouse. A cleaning brush 50 is installed on the housing 312. Figure 4As shown, the cleaning brush 50 is used to clean the photovoltaic panel 10 when the spool 31 rotates. It is made of polyester fiber or silicone and its width is the same as the width of the spool housing 312. The photovoltaic panel 10 is exposed to the outdoor environment for a long time, and its surface easily accumulates dirt such as dust, bird droppings, leaves, and pollen. This dirt blocks sunlight from reaching the photovoltaic panel 10, reducing the amount of light received and thus lowering its power generation efficiency. Therefore, using the cleaning brush 50 can effectively remove obstructions from the photovoltaic panel 10, ensuring that sunlight can fully reach it and improving power generation efficiency. Specifically, when the spool 31 winds up the photovoltaic panel 10, the cleaning brush 50 washes the photovoltaic panel 10 at its current position, removing dirt to a certain extent. When the photovoltaic panel 10 needs to be lowered, the AI ​​data module 20 sends a control command to the controller 32 to lower the photovoltaic panel 10. This causes the controller 32 to control the reel 31 to rotate in the opposite direction to the rotation direction of the reel 31 during winding. That is, if the photovoltaic panel 10 needs to be wound up, the rotation direction of the reel 31 is clockwise; if the photovoltaic panel 10 needs to be lowered, the rotation direction of the reel 31 is counterclockwise. Since the photovoltaic panel 10 is laid on the sloping roof of the greenhouse, it can rely on its own weight and light weight (generally less than 1 kg / m²) to lower the panel. 2The photovoltaic panels 10 are laid out on the greenhouse roof due to their smooth and flexible surface. The AI ​​data processing module 20 controls the rotation speed of the reel 31 to prevent excessively rapid release that could cause the photovoltaic panels 10 to pile up or wrinkle. Alternatively, a second reel module can be installed at the other end of the photovoltaic panel 10. The structure of the second reel module is the same as that of the reel module 30. The reel of the second reel module is connected to the other end of the photovoltaic panel 10 via a rope. When the photovoltaic panel 10 needs to be wound up, the rope on the reel of the second reel module moves along with the photovoltaic panel 10. When the photovoltaic panel 10 needs to be lowered, the AI ​​data processing module 20 controls the second reel module to pull the photovoltaic panel 10 wound into the reel module 30 and lay it on the greenhouse. After laying it on the greenhouse, a pressing device is used to press the photovoltaic panel 10 down to prevent it from being blown away by the wind. The edge device is electrically connected to the AI ​​data processing module 20, and an image sensor is installed on the second reel module. The image sensor is also electrically connected to the AI ​​data processing module 20. When the reel module 30 needs to wind up the photovoltaic panel 10, the AI ​​data processing module 20 controls the edge pressing device to loosen, so that the reel module 30 can wind up the photovoltaic panel. When the photovoltaic panel 10 needs to be lowered, the second reel module pulls out the photovoltaic panel 10 wound into the reel module 30 and lays it on the greenhouse. After the image sensor installed on the second reel module detects that the photovoltaic panel 10 has been laid, it transmits the information to the AI ​​data processing module 20. The AI ​​data processing module 20 sends a control command to the edge pressing device to make the edge pressing device press the photovoltaic panel 10. The specific model of the edge pressing device is MISUMIMHE2-10D, and the specific model of the image sensor is OV5647.

[0031] like Figure 5As shown, in some embodiments, the power-generating flexible semi-transparent photovoltaic greenhouse system also includes an environmental sensing module 60, which is installed inside the greenhouse and electrically connected to the AI ​​data processing module 20. The environmental sensing module 60 detects the crop growth environment inside the greenhouse, including temperature, humidity, light intensity, and carbon dioxide concentration, and transmits the relevant detection data to the AI ​​data processing module 20. When the AI ​​data processing module 20 determines that the current crop growth environment inside the greenhouse is not optimal (the edge computing control unit in the AI ​​data module 20 also deploys a database of various crop growth parameters), it can control the electronic controller 32 in the reel module 30 to retract and extend the photovoltaic panels 10, making the environment inside the greenhouse more suitable for crop growth. The retraction and extension of the photovoltaic panels 10 conforms to the crop growth pattern, greatly reducing the impact of changes in a single environmental factor on the photovoltaic panels. To minimize the risk of changes in environmental factors due to the opening and closing of greenhouses, and to maximize crop survival rates, the environmental sensing module 60 includes a temperature sensor 61, a humidity sensor 62, a light intensity sensor 63, and a carbon dioxide concentration sensor 64. These sensors are electrically connected to the AI ​​data processing module 20. They are evenly arranged inside the greenhouse and connected in parallel to fully detect the environmental conditions inside the greenhouse. The specific number of sensors depends on the size of the greenhouse. Compared to information processed by traditional data modules, the AI ​​data processing module 20 can coordinate information from multiple dimensions, taking into account the temperature, humidity, carbon dioxide concentration, and light intensity inside the greenhouse to control the operation of the photovoltaic panels 10, thereby achieving intelligent control of the greenhouse environment and reducing labor costs for farmers. Specifically, the temperature sensor 61 is a Sensirion STS35, the humidity sensor 62 is a SHT45, the light intensity sensor 63 is an Apogee SQ-500, and the carbon dioxide concentration sensor 64 is a Sensirion SCD30.

[0032] like Figure 6As shown, in some embodiments, the power-generating flexible semi-transparent photovoltaic greenhouse system further includes a power output module 70 for outputting the electrical energy generated by the photovoltaic panel 10 to external electrical equipment. The positive input terminal (Vin+) of the power output module 70 is electrically connected to the positive (+) terminal of the photovoltaic panel 10, and the negative input terminal (Vin-) is electrically connected to the negative (-) terminal of the photovoltaic panel 10. The output terminal (Vout) of the power output module 70 is electrically connected to the external electrical equipment. The external electrical equipment includes a greenhouse lighting system, an irrigation system, a temperature control system, and electrical equipment for farmers' greenhouse work. The power output module 70 can be installed inside or outside the greenhouse. For DC-powered devices, the power output module 70 needs to include a voltage converter and an energy storage battery. The voltage converter and the energy storage battery are electrically connected. The voltage converter is used to match the voltage of the electrical energy converted by the photovoltaic panel 10 with the voltage required by the electrical device, so that the output voltage meets the needs of the electrical device. The energy storage battery is used to store the electrical energy generated by the photovoltaic panel 10. When there is a need for electricity, the energy storage battery transmits the electrical energy to the electrical device to prevent the generated electrical energy from being wasted due to unused energy. For AC-powered devices, the power output module 70 includes a voltage converter, an energy storage battery, and an inverter. The voltage converter, energy storage battery, and inverter are electrically connected in sequence. The inverter is used to convert the DC power generated by the photovoltaic panel 10 into AC power. The specific model of the voltage converter is Victron Orion-Tr 48 / 24-30A, the specific model of the energy storage battery is CATL 48V 100Ah, and the specific model of the inverter is Growatt SPF5000ES.
