[0001] This patent relates to a smart home, in particular to an adaptive smart photovoltaic window system. Background Art
[0002] With the development of society, family, as the core of life, is becoming the focus of people's attention. Improving the quality of life has become one of the important goals pursued by people. Smart home, with the help of modern technology, has significantly improved the quality and efficiency of life and has become the focus of social attention. In the field of smart home, windows, as a bridge for indoor and outdoor communication, have attracted more and more attention in recent years, and the development of smart window technology has become a hot spot in international research. Especially those electrochromic glass windows that can change color, they can adjust the color of light entering the room as needed, block part of the light, thereby adjusting the indoor brightness and avoiding dizziness caused by excessive light. Such windows have been used in some homes and offices. However, these windows consume electricity and fail to effectively utilize excess light, which is not in line with the concept of energy saving and environmental protection. Therefore, people began to explore smart window solutions that are both energy-saving and environmentally friendly, and can adjust the intensity of indoor light. Photovoltaic power generation technology, which uses solar energy to generate electricity, meets the requirements of energy saving and environmental protection. Therefore, the smart photovoltaic window system built using photovoltaic power generation technology has attracted much attention recently. Guan Wenjing and others from Zhejiang Jinko Energy Co., Ltd. disclosed a patent (CN109750946A), demonstrating a window that uses photovoltaic cells to generate electricity; Zhang Guoqi from Femtosecond Optoelectronics Technology (Xi'an) Co., Ltd. disclosed a solar photovoltaic window assembly with a tracking system (CN103821446A), which uses a mechanical tracking system to enable photovoltaic cells to follow sunlight and improve photovoltaic power generation efficiency; Shi Mingjun and others from Hongtai Optoelectronics Technology Co., Ltd. disclosed a solar photovoltaic window with an adjustment device, which ensures that sunlight is always perpendicular to the solar photovoltaic panel through the adjustment device, thereby improving conversion efficiency. Although these devices can use the window position for photovoltaic power generation and are equipped with auxiliary devices to improve photovoltaic power generation efficiency, they mainly focus on the function of photovoltaic power generation and do not fully enhance the function of the window itself. A key function of windows is to transmit light and provide a suitable light intensity for the room, and the light intensity required for different time periods is different. Therefore, the window needs to be able to adjust the light intensity entering the room, which is one of its main functions. At present, the above-mentioned technology still needs to be improved in this regard. If it is to completely replace the existing windows, it is necessary to strengthen its function of adjusting the incident light intensity, so it has not yet been widely used. Summary of the invention
[0003] In order to achieve the object of the present invention, the present invention provides an adaptive intelligent photovoltaic window system, characterized in that the window is composed of an intelligent photovoltaic module (1) and two layers of encapsulation glass (2), the latter completely sealing the module (1). The intelligent photovoltaic module (1) is embedded with photovoltaic cells (3), which are located between the two layers of encapsulation glass (2), and guide rails (4) are provided at both ends of the photovoltaic cells (3), and there is a gap (5) between the cells. A photovoltaic cell storage box (8) is provided on one side of the module (1), which contains a controller (6), and the controller (6) is connected to two drive motors (7) through a data line (9), and the motors are located next to the guide rail (4). The controller (6) is responsible for controlling the operation of the drive motor (7), and then controlling the movement of the guide rail (4) to adjust the position of the photovoltaic cell (3) connected to the guide rail, thereby changing the size of the gap (5) between the cells to automatically adapt to the required sunlight intensity indoors. The storage box (8) is also provided with a control motor (10), which is connected to the controller (6) through a data line (9). The control motor (10) is used to drive the movement of the manipulator (11), and the manipulator (11) is connected to both sides of the photovoltaic cell (3) through the manipulator interface (12) so as to move the cell (3) along the guide rail (13) in the storage box (8). Both ends of the cell (3) are connected to the guide rail (13) through the card slot (14). The beneficial effects of this include: The intelligent photovoltaic window system involved in the present invention has an adaptive function. By changing the spacing of photovoltaic cells in the photovoltaic module, the light transmittance of the window can be adjusted to control the indoor light level. This adjustment mechanism integrates mechatronics technology and uses artificial intelligence to achieve the ability to automatically adjust the light transmittance of the photovoltaic window in real time according to actual needs, so that it can automatically adapt to changes in indoor light intensity. In contrast, the existing intelligent photovoltaic window system mainly changes the color of the window glass by adjusting the voltage, thereby adjusting the light transmittance. However, the adjustment ability of this method is limited, and the light transmittance cannot be flexibly adjusted according to the demand for indoor light intensity. At the same time, it does not generate electricity, but consumes electricity, does not meet environmental protection standards, and cannot meet the requirements of modern buildings for energy conservation and environmental protection. Another method is to use a semi-transparent photovoltaic film, such as cadmium telluride, polycrystalline silicon, etc., which has the advantage of being able to generate photovoltaic power and meet the energy conservation and environmental protection standards of modern buildings, but once the film material is made, the light transmittance is fixed, the light transmittance cannot be adjusted in time according to actual needs, and its light transmittance cannot be adjusted according to demand. Traditional windows, whether blinds or curtains, can also achieve a certain degree of light intensity adjustment, but they require manual operation and have a limited adjustment range. The photovoltaic windows constructed by the present invention can achieve arbitrary adjustment of the incident light intensity according to the requirements of indoor light intensity. By equipping with appropriate sensors and algorithms and using a controller, photovoltaic windows can automatically adapt to changes in indoor light intensity and show excellent adaptive performance. In addition, the controller used can be implanted with an AI program to accumulate data such as light intensity, ambient weather and temperature that users usually use. Through AI deep learning, the user's usage habits can be understood, the default settings of the controller can be optimized, and the convenience of users using the system can be improved. It can also be connected with the control data of similar photovoltaic windows and usage requirements in the surrounding area through the Internet of Things, learn from each other and optimize, so that the selection of control parameters is more reasonable, the adaptive ability of the system is improved, and a more comfortable light intensity is provided for the use space.
[0004] The intelligent photovoltaic window system involved in the present invention has excellent light transmittance uniformity and high light transmittance quality. Light transmittance is achieved by spacing the photovoltaic cells in the photovoltaic module. These spacings are arranged in an equidistant manner, and can also be arranged in a differentiated nonlinear manner according to needs. For example, under specific needs, the spacing in the middle of the window can be increased, while the spacing on both sides can be reduced, so as to enhance the light transmittance of the middle part of the window to meet the visual needs when looking far away; at the same time, the arrangement of the cells can also form a specific pattern to achieve an artistic visual effect. In contrast, traditional curtain windows or blinds are completely opaque when blocking and cannot achieve these functions; and electrochromic windows and photovoltaic film windows are also difficult to meet the needs of nonlinear distribution of window light transmittance intensity.
[0005] The intelligent photovoltaic window system involved in the present invention has no special requirements on the material of the photovoltaic cells used. It can use translucent photovoltaic thin-film cells or most commercial photovoltaic cells including monocrystalline silicon and polycrystalline silicon. When silicon-based photovoltaic cells are used to form the photovoltaic module of the present invention, not only the environmental advantages and mature technology of silicon-based cells are brought into play, but also cost-effectiveness is brought about, thereby expanding the application range of silicon-based cells.
[0006] The present invention relates to an intelligent photovoltaic window system, which can intelligently adjust the light transmission intensity. The process receives user instructions through a controller, and supports multiple input methods such as panel input, voice input or remote mobile phone operation. The algorithm program in the controller calculates the required parameters and generates control commands to drive the motor to move, thereby adjusting the spacing of photovoltaic cells and realizing precise control of the light transmission intensity of the window. This timely intelligent adjustment method ensures that the window has an ideal light transmission intensity, so that the interior of the building can obtain the required light distribution, significantly improves the comfort of the indoor environment, and is suitable for building livable buildings.
[0007] The present invention relates to an intelligent photovoltaic window system, wherein the photovoltaic module used in the system includes a photovoltaic cell. In order to achieve more accurate light transmission intensity adjustment, a photovoltaic cell with a smaller width is generally used, and the size is in the centimeter level. Compared with the traditional large-sized and expensive photovoltaic cells, the small-sized photovoltaic cells can be manufactured using a smaller-sized single-crystal silicon material. This approach not only helps to reduce the production cost of photovoltaic cells, but also has a relatively low probability of color difference in small-sized cells, so it is more ideal in visual effect. In addition, since the photovoltaic cells in the photovoltaic window often need to be moved, the sensitivity of the entire photovoltaic window to the color difference of the photovoltaic module is not as strong as that of the solid-block photovoltaic window. Therefore, the anti-color difference requirements for the components are not as strict as those for large-sized fixed photovoltaic windows. In order to meet the environmental requirements for the color cleanliness of the photovoltaic window, it is only necessary to perform a simple treatment on the surface glass, such as processing into a concave condenser array and the like to increase the utilization efficiency of sunlight, and slow down the color difference by increasing the optical path and light reflection, so that the environmental requirements for the color cleanliness of the photovoltaic window can be basically met, and silicon-based photovoltaic cells can be used, which has positive significance for the development of photovoltaic windows.
[0008] The photovoltaic windows covered by the present invention have the remarkable characteristics of easy installation and fast construction. Specifically, photovoltaic cells are cleverly embedded between two layers of glass to form a photovoltaic module. This design not only ensures the modular characteristics of the module, but also makes the modular production process more efficient. The modular photovoltaic module greatly simplifies the installation process, allowing construction workers to complete the installation task easily and quickly. In addition, fasteners for fixing the components can be pre-designed between the supporting structure of the window and the photovoltaic module. The presence of these fasteners further enhances the convenience of installation and ensures that the photovoltaic module module can be installed in place at a faster speed and higher efficiency. In general, the photovoltaic windows of the present invention are not only innovative in design, but also demonstrate significant installation advantages in practical applications, greatly improving construction efficiency and convenience.
[0009] The present invention relates to an intelligent photovoltaic window system, which adopts a double-layer encapsulated glass structure to effectively protect the internal photovoltaic cells from damage and avoid direct exposure to adverse weather conditions, thereby extending the service life of the battery and ensuring the stable operation of the system. Compared with traditional single-layer glass windows, the double-layer glass structure not only improves the thermal insulation performance, but also brings a significant "warm in winter and cool in summer" effect, thereby improving the living comfort.
[0010] The photovoltaic windows of the present invention are also designed to be integrated with modern architectural aesthetics. By adopting advanced materials and manufacturing technologies, photovoltaic windows not only have high-efficiency power generation capabilities, but also can be perfectly integrated with the exterior design of the building, adding a sense of modernity and technology to the building. Its transparent or translucent characteristics enable the building to make full use of natural light during the day and reduce the energy consumption of indoor lighting. At the same time, photovoltaic windows can also be used as decorative lighting for buildings at night, showing a unique visual effect.
[0011] In terms of environmental protection, the photovoltaic windows of the present invention also perform well. Since they can effectively use solar energy to generate electricity, they help reduce dependence on traditional fossil energy and reduce carbon emissions. In addition, the use of photovoltaic windows can also reduce heat loss inside buildings, improve energy utilization efficiency, and further promote sustainable environmental development.
[0012] In terms of safety, the photovoltaic window of the present invention has also been carefully designed. The photovoltaic cells are embedded between the glass, which not only improves the stability of the structure, but also effectively prevents the cells from being directly exposed to the external environment, thereby extending the service life of the photovoltaic window. At the same time, this design can also prevent the cells from being damaged in extreme weather conditions, ensuring the stable operation of the photovoltaic window in various environments.
[0013] In summary, the intelligent adaptive photovoltaic window system of the present invention, while realizing photovoltaic power generation, enhances the light transmission performance of the window as the main light-transmitting component of the room, so that it has a better use effect. Its large-scale application will help to improve the living comfort of the room and meet the zero-emission goal of modern buildings. When this intelligent adaptive photovoltaic window system is used in conjunction with photovoltaic windows, the effect is better. The intelligent adaptive photovoltaic window system of the present invention is not only technologically innovative, but also demonstrates many advantages in practical applications. It can not only provide clean energy for modern buildings, but also improve the comfort of living and working, while meeting the requirements of environmental protection and sustainable development. With the continuous advancement of photovoltaic technology and the further reduction of costs, this intelligent photovoltaic window system is expected to be widely used in the future construction market.
