Description

Technical Field

[0001] This invention relates to the field of intelligent building technology, and more specifically, to a method for installing electrically operated louvered glass. Background Technology

[0002] With the development of building energy-saving technologies, motorized louvered glass, as a new type of intelligent shading system, is gradually being applied in modern buildings. Traditional louvered window control methods are mostly manual or timed, but these methods cannot meet real-time, precise shading needs, especially in applications under different seasons and lighting conditions. Motorized louvered glass systems, by automatically adjusting the louver angle, achieve intelligent control of indoor lighting, improving indoor comfort and energy efficiency. Therefore, how to efficiently and accurately install this motorized louvered glass system is a problem that urgently needs to be solved in modern buildings. Summary of the Invention

[0003] To overcome the aforementioned deficiencies of the prior art, the present invention provides an installation method for motorized louvered glass. This method involves installing a motor, a transmission device, a light sensor, and a control system, combined with a fuzzy control algorithm, to achieve automatic adjustment of the louver angle. This method can respond in real time to changes in light intensity, ensuring dynamic optimization of indoor lighting, reducing manual adjustment and air conditioning load, and lowering energy consumption, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A method for installing electrically operated louvered glass includes the following steps:

[0006] Step S1: Fix the frame and bracket to the window frame. The bracket is closely fitted with the external structure of the building to ensure the long-term stability of the motorized louvered glass.

[0007] Step S2: Install the motor in the predetermined position. The transmission device is linked to the motor through the transmission shaft, and the motor is adjusted by rotation.

[0008] Step S3: Install the motorized louvered glass panels sequentially onto the fixed bracket. Each motorized louvered glass panel can be adjusted in angle via an electric drive system.

[0009] Step S4: Install a light sensor at the window frame to monitor indoor and outdoor light intensity in real time. Based on the fuzzy control algorithm, the control system dynamically adjusts the angle of the motorized louvered glass according to changes in light intensity.

[0010] Step S5: Connect the power supply for the motorized louvers to the building's electrical grid.

[0011] The fuzzy control algorithm includes the following steps:

[0012] Step M1: Convert the light intensity L into a fuzzy linguistic variable, whereby the linguistic variable represents different light intensity ranges. The light intensity L has the following fuzzy ranges:

[0013] Low light intensity: Light intensity is below the preset threshold, indicating a weak light intensity.

[0014] Medium light intensity: equal to the preset light intensity threshold, representing a moderate light intensity situation;

[0015] High illumination: Light intensity exceeding a preset threshold, representing a strong illumination situation; the fuzzy value of the illumination intensity L is represented as: L={Low,Medium,High}, and the membership function of the fuzzy set is described by the following formula: Among them, L min L is the preset minimum light intensity. max L is the preset maximum light intensity. mid L is the preset median value of light intensity. width The width represents the light intensity.

[0016] In step M2, the angle θ of the motorized louvered glass is also a fuzzy quantity, described by the following intervals:

[0017] Small angle: This indicates that the motorized blinds are completely closed to prevent direct sunlight from entering;

[0018] Medium angle: indicates that the motorized blinds open at a medium angle;

[0019] Large angle: indicates that the motorized louvered glass opens at a large angle; the angle θ of the motorized louvered glass is blurred into θ = {Small, Medium, Large};

[0020] Step M3, during the defuzzification process, is the final output of the angle of the motorized louvered glass. Where, θ d To determine the final angle of the defuzzified motorized louvered glass, μ(θ) i θ represents the membership degree of the fuzzy output value. i For the corresponding angle.

[0021] As a further aspect of the invention, the installation of motorized louvered glass includes an electric motor, a transmission device, motorized louvered glass, a light sensor, a control system, and a frame and support compatible with the building structure. The electric motor provides power to drive the rotation and adjustment of the motorized louvered glass. The electric motor works closely with the transmission device, which transmits the power generated by the electric motor to the motorized louvered glass through mechanical structures such as drive shafts, gears, and pulleys. The transmission device includes a reducer, a servo motor, or a stepper motor. Through these drive modules, the motorized louvered glass system can control the angle changes of the motorized louvered glass, thereby adjusting indoor lighting and temperature. The motorized louvered glass uses high-strength, lightweight glass materials to ensure sufficient rigidity and durability during operation. The surface of the motorized louvered glass is coated or uses high-reflectivity materials to further enhance its shading and reflection capabilities. The light sensor monitors changes in indoor and outdoor light intensity in real time and feeds this data back to the control system. Based on the real-time feedback from the sensor, the control system can determine whether the current light intensity has reached a preset threshold, and then adjust the angle of the motorized louvered glass to optimize indoor lighting conditions and temperature. The control system is responsible for receiving feedback signals from the light sensor and determining the adjustment angle of the motorized louvered glass according to a predetermined control algorithm. The frame and bracket, which are compatible with the building structure, are customized according to the building's structure and dimensions to ensure that the motorized louvered glass system can be stably installed on the glass curtain wall. The frame material is made of high-strength aluminum alloy.

[0022] As a further aspect of the present invention, in step S1, the frame and bracket not only bear the weight of the entire motorized louvered glass system, but also determine the system's stability and long-term operating performance. First, the dimensions and installation positions of the frame and bracket are determined according to the design specifications of the building windows.

[0023] In practical applications, the requirements of Appendix E.5 (Table of Snow Pressure and Wind Pressure Values ​​for Cities Nationwide) of the current national standard "Load Code for Design of Building Structures" (GB50009-2012), "Load Code for Design of Building Structures" (GB50009-2012), and the provisions of the "Unified Standard for Reliability Design of Building Structures" (GB50068-2018) shall apply. For large glass curtain walls, the design of the frame and supports must calculate the load-bearing capacity of the curtain wall. The calculation of the load-bearing capacity of the curtain wall includes the following steps:

[0024] Step Y1, Calculation of horizontal wind load: Based on a 50-year return period, the basic wind pressure value is taken as W0 = 0.4 kN / m. 2 The calculated elevation of the curtain wall project is 9.39m, and the ground roughness category is Class B terrain. Therefore, the gust coefficient β can be obtained. gz=1.7, wind pressure height variation coefficient μ z =1;

[0025] Step Y2, Panel Wind Load Calculation: The glass panel is considered as an enclosure component directly bearing wind loads; therefore, the shape factor is not reduced. Thus, the shape factor for the negative pressure zone of the wall surface in this project (enclosed building) is: μ s1 =1 + 0.2 = 1.2. According to section 5.3.2 of standard JGJ102-2003, the standard value W for wind load on glass panels is... k It should not be less than 0.001 N / mm 2 Therefore, this project W k =0.001N / mm 2 ;

[0026] Step Y3, the design value of the wind load acting on the curtain wall is: W = γ w ·W k Where W is the design value of the wind load acting on the curtain wall, and γ w Let γ be the wind load partial factor. w The design value of the wind load acting on the curtain wall is: W = 1.5 × 0.001 = 0.0015 N / mm². 2 .

[0027] The bracket is made of aluminum alloy, a material that not only has strong load-bearing capacity but also corrosion resistance, making it suitable for long-term outdoor environments. During installation, the bracket's horizontal and vertical alignment is ensured using laser measuring instruments or a level to prevent instability in the motorized louvered glass system due to tilted or asymmetrical installation. The bracket is bolted to the building frame. Furthermore, appropriate insulating pads or cushioning materials are placed between the bracket and the frame to reduce impacts from temperature changes, vibrations, or wind.

[0028] As a further aspect of the present invention, in step S2, the motor is installed on the side near the window frame and is compatible with the building structure. The motor can be a DC motor, an AC motor, or a servo motor. When installing the motor, its shaft needs to be aligned with the input shaft of the transmission device to ensure the efficiency and stability of power transmission. Bolts, brackets, or mounting frames are used to secure the motor to prevent vibrations generated during operation from affecting its normal operation.

[0029] The transmission device transmits the rotational power generated by the motor to the motorized louvered glass via a drive shaft, gears, belts, or chains, thereby enabling the rotational adjustment of the louvered glass. The transmission device consists of multiple gears, bearings, pulleys, etc., and the gear ratio and friction coefficient are designed according to the size, weight, and required adjustment speed of the motorized louvered glass. Furthermore, the housing of the transmission device and the motor itself should have good heat dissipation performance, as the motor generates heat during prolonged operation; poor heat dissipation may lead to overheating and damage to the motor.

[0030] As a further aspect of the present invention, in step S3, the motorized louvered glass panels are sequentially installed onto the pre-fixed bracket. To ensure the normal operation of the motorized louvered glass panels, the gap between the bracket and the panels needs to be precisely controlled to avoid friction and resistance caused by uneven or excessively tight gaps. The motorized louvered glass panels are connected to the bracket via hinges or bearings. When installing the motorized louvered glass panels, installers need to use a level or laser measuring tool to ensure that the installation angle of each panel is correct and that the angles are not inconsistent due to installation errors. To ensure that each panel is precisely aligned after installation, positioning tools or fixing clamps are used to temporarily fix the panels, ensuring that they do not shift or deform during installation. The adjustable angle range of the motorized louvered glass panels is 0° to 90°. When fixing the panels, a professional adjustment device is used to adjust each panel to the predetermined angle, and then the panels are firmly fixed using a fixing device, such as bolts or locking devices, to ensure that the panels do not loosen or shift during long-term use.

[0031] As a further aspect of the present invention, in step S4, the light sensor, as a sensing component, is installed near the window frame to accurately and in real-time monitor the intensity of light entering the room. Simultaneously, the light sensor should avoid direct exposure to the shadow areas of windows or skylights and should also be protected from excessive interference from external environmental factors (such as building shadows or weather changes). The light sensor can continuously sense and capture changes in the intensity of natural light and feed this data back to the control system in real time.

[0032] Real-time feedback on changes in lighting allows the control system to respond quickly and automatically adjust the angle of the motorized blinds according to varying ambient light intensity, maximizing energy efficiency. When external light intensity increases, the blinds automatically open, allowing more natural light into the room and reducing the need for artificial lighting; when light intensity is too high, the motorized blinds automatically adjust to a suitable angle, reducing the impact of solar radiation on indoor temperature and lowering the air conditioning load. This adaptive adjustment mechanism maximizes the use of natural light during the day and reduces heat loss at night by closing the motorized blinds, thereby improving energy efficiency and reducing unnecessary energy consumption.

[0033] As a further aspect of the present invention, in step S5, the power supply of the motorized louvered glass needs to be connected to the building's power grid to ensure a stable power supply for the motor, light sensor, and control system. After the power connection is completed, the debugging phase begins. During debugging, the working status of each component is first checked, ensuring that the motor can start and run smoothly, and that the transmission device can smoothly drive the rotation of the motorized louvered glass without any jamming. Then, the light sensor is calibrated to ensure that it can accurately and in real-time sense changes in indoor and outdoor light intensity and transmit the data to the control system.

[0034] The technical effects and advantages of this invention's method for installing electrically operated louvered glass are as follows: This invention achieves automatic adjustment of the louver angle by precisely installing a motor, transmission device, light sensor, and control system, combined with a fuzzy control algorithm. It can respond in real-time to changes in light intensity, ensuring dynamic optimization of indoor lighting, reducing manual adjustments and air conditioning load, and lowering energy consumption. Furthermore, the system's intelligent control and automated adjustment greatly improve ease of use, meeting the needs under different lighting conditions, and maximizing the use of natural light through precise adjustment, providing an energy-saving and comfortable environment. Compared with traditional shading systems, this invention has higher automation, flexibility, and efficiency, and is widely applicable to the application needs of modern intelligent buildings, with significant energy-saving, environmental protection, and comfort improvements.

[0045] Example 1

[0046] See Figure 1 The flowchart shown illustrates an embodiment of the present invention that provides a method for installing electrically operated louvered glass, comprising the following steps:

[0047] Step S1: Fix the frame and bracket to the window frame. The bracket is closely fitted with the external structure of the building to ensure the long-term stability of the motorized louvered glass.

[0048] Step S2: Install the motor in the predetermined position. The transmission device is linked to the motor through the transmission shaft, and the motor is adjusted by rotation.

[0049] Step S3: Install the motorized louvered glass panels sequentially onto the fixed bracket. Each motorized louvered glass panel can be adjusted in angle via an electric drive system.

[0050] Step S4: Install a light sensor at the window frame to monitor indoor and outdoor light intensity in real time. Based on the fuzzy control algorithm, the control system dynamically adjusts the angle of the motorized louvered glass according to changes in light intensity.

[0051] Step S5: Connect the power supply for the motorized louvers to the building's electrical grid.

[0052] Furthermore, the installation of motorized louvered glass requires an electric motor, transmission device, louvered glass, light sensor, control system, and a frame and bracket compatible with the building structure. The electric motor provides power to drive the rotation and adjustment of the louvered glass. The electric motor works closely with the transmission device, which transmits the power generated by the electric motor to the louvered glass through mechanical structures such as drive shafts, gears, and pulleys. The transmission device includes a reducer, servo motor, or stepper motor. Through these drive modules, the motorized louvered glass system can control the angle change of the louvered glass, thereby adjusting indoor light and temperature. The louvered glass uses high-strength, lightweight glass material to ensure sufficient rigidity and durability during operation. The surface of the louvered glass is coated or uses high-reflective materials to further enhance its shading and reflection capabilities. The light sensor... Sensors monitor changes in indoor and outdoor light intensity in real time and feed this data back to the control system. Based on the real-time feedback from the sensors, the control system can determine whether the current light intensity has reached a preset threshold, and then adjust the angle of the louvers to optimize indoor lighting conditions and temperature. The control system is responsible for receiving feedback signals from the light sensors and determining the adjustment angle of the louvers according to a predetermined control algorithm. The frame and brackets, which are compatible with the building structure, are customized according to the building's structure and dimensions to ensure that the louver system can be stably installed on the glass curtain wall. The frame material is made of high-strength aluminum alloy.

[0053] Furthermore, in step S1, the frame and supports not only bear the weight of the entire louvered glass system but also determine the system's stability and long-term operational performance. First, the dimensions and installation positions of the frame and supports are determined according to the building's window design specifications. For large glass curtain walls, the design of the frame and supports must calculate the curtain wall's load-bearing capacity. This calculation includes the following steps:

[0054] Step Y1, Calculation of horizontal wind load: According to Appendix E.5 (Table of snow pressure and wind pressure values ​​for cities across the country) of the current national standard "Load Code for Design of Building Structures" (GB50009-2012), the basic wind pressure value is taken as W0 = 0.4 kN / m². 2 The calculated elevation of the curtain wall project is 9.39m, and the ground roughness category is Class B terrain. According to the current national standard "Load Code for Design of Building Structures" (GB50009-2012), the gust coefficient β can be obtained. gz =1.7, wind pressure height variation coefficient μ z =1;

[0055] Step Y2, Calculation of wind load on the glass panel: According to the current national standard "Load Code for Design of Building Structures" (GB50009-2012), the glass panel is considered as an enclosure component directly bearing wind loads, and the shape coefficient is not reduced. Therefore, the shape coefficient of the negative pressure zone on the wall of this project (enclosed building) is: μ s1 =1 + 0.2 = 1.2. According to section 5.3.2 of standard JGJ102-2003, the standard value W for wind load on glass panels is... k It should not be less than 0.001 N / mm 2 Therefore, this project W k =0.001N / mm 2 ;

[0056] Step Y3, the design value of the wind load acting on the curtain wall is: W = γ w ·W k Where W is the design value of the wind load acting on the curtain wall, and γ w The wind load partial factor is taken as γ according to Article 8.2.9 of the current national standard "Unified Standard for Reliability Design of Building Structures" (GB50068-2018). w Therefore, the design value of the wind load acting on the curtain wall is: W = 1.5 × 0.001 = 0.0015 N / mm². 2 .

[0057] The bracket is made of aluminum alloy, a material that not only has strong load-bearing capacity but also corrosion resistance, making it suitable for long-term outdoor environments. During installation, the bracket's horizontal and vertical alignment is ensured using laser measuring instruments or a level to prevent instability in the louvered glass system due to tilted or asymmetrical installation. The bracket is bolted to the building frame. Furthermore, appropriate insulating pads or cushioning materials are placed between the bracket and the frame to reduce impacts from temperature changes, vibrations, or wind.

[0058] Furthermore, in step S2, the motor is installed on the side near the window frame and is compatible with the building structure. The motor can be a DC motor, an AC motor, or a servo motor. When installing the motor, its shaft needs to be aligned with the input shaft of the transmission device to ensure efficient and stable power transmission. Bolts, brackets, or mounting frames are used to secure the motor to prevent vibrations generated during operation from affecting its normal operation.

[0059] The transmission device transmits the rotational power generated by the electric motor to the louvered glass via a drive shaft, gears, belts, or chains, thereby enabling the rotational adjustment of the louvered glass. The transmission device consists of multiple gears, bearings, pulleys, etc., and the gear ratio and coefficient of friction are designed according to the size and weight of the louvered glass and the required adjustment speed. Furthermore, the housing of the transmission device and the electric motor itself should have good heat dissipation performance, as the electric motor generates heat during prolonged operation; poor heat dissipation may lead to overheating and damage to the motor.

[0060] Further, in step S3, the louvered glass panels are sequentially installed onto the fixed bracket. To ensure the normal operation of the louvered glass panels, the gap between the bracket and the louvered glass panels needs to be precisely controlled to avoid friction and resistance caused by uneven or excessively tight gaps. The louvered glass panels are connected to the bracket via hinges or bearings. When installing the louvered glass panels, the installer needs to use a level or laser measuring tool to ensure that the installation angle of each louvered glass panel is correct and that the angle of the louvered glass panels is not inconsistent due to installation errors. To ensure that each louvered glass panel is accurately aligned after installation, positioning tools or fixing clamps are used to temporarily fix the louvered glass panels to ensure that they do not shift or deform during installation. The adjustment angle range of the louvered glass panels is 0° to 90°. When fixing the louvered glass panels, a professional adjustment device is used to adjust each louvered glass panel to the predetermined angle, and then the louvered glass panels are firmly fixed by a fixing device, which is a bolt or locking device, to ensure that the louvered glass panels do not loosen or shift during long-term use.

[0061] Furthermore, in step S4, the light sensor, as a sensing component, is installed near the window frame to accurately monitor the intensity of light entering the room in real time. Simultaneously, the light sensor should avoid direct exposure to the shadows of windows or skylights and should also be protected from excessive interference from external environmental factors (such as building shadows or weather changes). Through this installation, the light sensor can continuously sense and capture changes in the intensity of natural light and feed this data back to the control system in real time.

[0062] When the light sensor is working, it emits an electrical signal based on the ambient light intensity. The control system analyzes and processes this electrical signal. The control system uses a fuzzy control algorithm to dynamically adjust the electrical signal, calculating the optimal angle of the blinds to achieve optimal light adjustment. The fuzzy control algorithm includes the following steps:

[0063] Step M1: Convert the light intensity L into a fuzzy linguistic variable, whereby the linguistic variable represents different light intensity ranges. The light intensity L has the following fuzzy ranges:

[0064] Low light intensity: Light intensity is below the preset threshold, indicating a weak light intensity.

[0065] Medium light intensity: equal to the preset light intensity threshold, representing a moderate light intensity situation;

[0066] High illumination: Light intensity exceeding a preset threshold, representing a strong illumination situation; the fuzzy value of the illumination intensity L is represented as: L={Low,Medium,High}, and the membership function of the fuzzy set is described by the following formula: Among them, L min L is the preset minimum light intensity. max L is the preset maximum light intensity. mid L is the preset median value of light intensity. width The width represents the light intensity.

[0067] In step M2, the angle θ of the venetian blinds is also a fuzzy quantity, described by the following intervals:

[0068] Small angle: This means the louvers are completely closed to prevent direct sunlight from entering.

[0069] Medium angle: indicates that the louvers are opened at a medium angle;

[0070] Large angle: indicates that the venetian blinds are opened at a large angle; the angle θ of the venetian blinds is blurred to θ = {Small, Medium, Large};

[0071] Step M3, during the deblurring process, is the final output of the venetian blind angle. Where, θ d To determine the final angle of the deblurred venetian blinds, μ(θ) i θ represents the membership degree of the fuzzy output value. i For the corresponding angle.

[0072] Real-time feedback on changes in light intensity enables the control system to respond quickly and automatically adjust the angle of the blinds according to different ambient light intensities, maximizing energy efficiency. When external light intensity increases, the blinds automatically open, allowing more natural light into the room and reducing the need for artificial lighting; when light intensity is too high, the blinds automatically adjust to a suitable angle to reduce the impact of solar radiation on indoor temperature and lower the air conditioning load. Through this adaptive adjustment mechanism, natural light is maximized during the day, while heat loss is reduced at night by closing the blinds, thereby improving energy efficiency and reducing unnecessary energy consumption.

[0073] Furthermore, in step S5, the power supply for the motorized louvered glass needs to be connected to the building's power grid to ensure a stable power supply for the motor, light sensor, and control system. After the power connection is completed, the debugging phase begins. During debugging, the working status of each component is first checked, ensuring the motor can start and run smoothly, and that the transmission device can smoothly drive the rotation of the louvered glass without any jamming. Then, the light sensor is calibrated to ensure it can accurately and in real-time sense changes in indoor and outdoor light intensity and transmit the data to the control system.

[0074] In this embodiment, refer to Figure 2 The schematic diagram shows that the motorized louvered glass is installed at axis G / 4-1. (See attached diagram.) Figure 3 The schematic diagram shows that the motorized louvered glass is installed at axis 1 / G-E. See also...
