[0001] The present invention relates to the technical field of intelligent buildings, and more particularly to a method for installing electric shutter glass. Background Art

[0002] With the development of building energy-saving technology, electric blinds are gradually being used in modern buildings as a new type of intelligent shading system. Traditional blinds are mostly controlled manually or by timing, but these methods cannot meet the real-time and accurate shading needs, especially in different seasons and under different lighting conditions. The electric blinds system can achieve intelligent control of indoor lighting by automatically adjusting the angle of the blinds, thereby improving indoor comfort and energy-saving efficiency. Therefore, how to efficiently and accurately install this electric blinds system is an urgent problem to be solved in modern buildings. Summary of the invention

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a method for installing electric venetian blinds, which is achieved by installing a motor, a transmission device, a light sensor and a control system, combined with a fuzzy control algorithm to realize automatic adjustment of the angle of the venetian blinds, and can respond to changes in light intensity in real time to ensure dynamic optimization of indoor lighting, reduce manual adjustment and air-conditioning load, and reduce energy consumption, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A method for installing an electric blind glass comprises the following steps:

[0006] Step S1, fixing the frame and the bracket on the window frame, the bracket is closely matched with the external structure of the building to ensure the long-term stability of the electric blind glass;

[0007] Step S2, installing the motor at a predetermined position, the transmission device is linked with the motor through the transmission shaft, and the electric blind glass is driven to be adjusted by rotation;

[0008] Step S3, installing the electric louver glass on the fixed bracket in sequence, and the angle of each electric louver glass can be adjusted by the electric drive system;

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

[0010] Step S5, connecting the power supply of the electric blind glass to the power grid of the building;

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

[0012] Step M1, converting the light intensity L into a fuzzy linguistic variable, wherein the linguistic variable represents different light intensity intervals. The light intensity L has the following fuzzy intervals:

[0013] Low light: below the preset light intensity threshold, indicating low light intensity;

[0014] Medium: equal to the preset light intensity threshold, indicating medium light intensity;

[0015] High light intensity (High): higher than the preset light intensity threshold, indicating a strong light intensity; the fuzzy value of the light intensity L is expressed as: L = {Low, Medium, High}, and the membership function of the fuzzy set is described by the following formula: Among them, L min is the preset minimum light intensity, L max is the preset maximum light intensity, L mid is the preset middle value of light intensity, L width is the width of the light intensity;

[0016] Step M2, the angle θ of the electric blinds is also a fuzzy quantity, which is described by the following intervals:

[0017] Small angle: means the electric blinds are completely closed to prevent direct sunlight from entering;

[0018] Medium: means the electric blinds are opened at a medium angle;

[0019] Large angle: indicates that the electric blinds are opened at a large angle; the electric blinds angle θ is fuzzy as θ = {Small, Medium, Large};

[0020] Step M3, in the defuzzification process, the final output of the electric blinds glass angle Among them, θ d is the final angle of the electric blinds after defuzzification, μ(θ i ) is the membership degree of the fuzzy output value, θ i is the corresponding angle.

[0021] As a further solution of the present invention, the electric motor, transmission device, electric venetian blinds, light sensors, control system, and frames and brackets compatible with the building structure required for the electric venetian blinds are installed. The motor provides power to drive the rotation and adjustment of the electric venetian blinds. The motor is closely matched with the transmission device, and the function of the transmission device is to transmit the power generated by the motor to the electric venetian blinds through mechanical structures such as transmission shafts, gears, and pulleys. The transmission device includes a reducer, a servo motor or a stepper motor. Through these drive modules, the electric venetian blinds system can control the angle change of the electric venetian blinds, thereby adjusting the indoor light and temperature; the electric venetian blinds are made of high-strength, lightweight glass materials to ensure that they have sufficient rigidity and durability during operation. The surface of the electric venetian blinds is coated or made of highly reflective materials to further enhance its shading and reflection capabilities; the light The light sensor monitors the changes in indoor and outdoor light intensity in real time, and feeds back these data to the control system. According to 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 electric louver glass to optimize the indoor lighting conditions and temperature; the control system is responsible for receiving the feedback signal from the light sensor, and determining the adjustment angle of the electric louver glass according to a predetermined control algorithm; the frame and bracket compatible with the building structure are customized according to the structure and size of the building to ensure that the electric louver glass system can be firmly installed on the glass curtain wall, and the frame material is made of high-strength aluminum alloy.

[0022] As a further solution of the present invention, in step S1, the frame and the bracket not only bear the weight of the entire electric blind glass system, but also determine the stability and long-term operation effect of the system. First, the size and installation position of the frame and the bracket are determined according to the design specifications of the building windows.

[0023] In practical application, the current national standard "Code for Loads on Building Structures" (GB50009-2012) Appendix E.5 (Table of Snow Pressure and Wind Pressure Values ​​for Cities Nationwide), "Code for Loads on Building Structures" (GB50009-2012), "Code for Loads on Building Structures" (GB50009-2012) requirements, and "Uniform Standard for Reliability Design of Building Structures" (GB50068-2018) are implemented. For large glass curtain walls, the design of frames and brackets must calculate the load-bearing capacity of the curtain wall, and 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, take the basic wind pressure value 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. The gust coefficient β is: gz=1.7, wind pressure height variation coefficient μ z =1;

[0025] Step Y2, panel wind load calculation: The glass panel is regarded as a protective component that directly bears the wind load, and the shape coefficient is not reduced. Therefore, the shape coefficient of the negative pressure area of ​​the wall of this project (enclosed building) is: μ s1 =1+0.2=1.2, according to 5.3.2 of JGJ102-2003, the standard value of wind load on glass panel is W k Should not be less than 0.001N / mm 2 , so 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 wind load acting on the curtain wall, γ w is the wind load partial factor, take the wind load partial factor γ w =1.5, the design value of wind load acting on the curtain wall is: W = 1.5 × 0.001 = 0.0015 N / mm 2 .

[0027] The bracket is made of aluminum alloy material, which not only has a strong load-bearing capacity, but also is corrosion-resistant and can adapt to long-term outdoor environments. When installing the bracket, a laser measuring instrument or a level is used to ensure the horizontality and verticality of the bracket to avoid unstable operation of the electric blind glass system due to tilted or asymmetrical installation of the bracket. The bracket is connected to the building frame by bolts. In addition, appropriate isolation pads or buffer materials need to be set between the bracket and the frame to reduce the impact caused by temperature changes, vibrations or wind.

[0028] As a further solution of the present invention, in step S2, the motor is installed on a side close to the window frame and is compatible with the building structure. The motor is selected from a DC motor, an AC motor or a servo motor. When installing the motor, the axis needs to be docked with the input shaft of the transmission device to ensure the efficiency and stability of power transmission. The motor is fixed with bolts, brackets or mounting brackets to prevent vibration generated during operation from affecting the normal operation of the motor.

[0029] The function of the transmission device is to transmit the rotational power generated by the motor to the electric blinds through a transmission shaft, gears, belts or chains, so as to realize the rotation adjustment of the electric blinds. The transmission device is composed of a plurality of gears, bearings, pulleys, etc. The transmission ratio and friction coefficient of the gears are designed according to the size, weight and required adjustment speed of the electric blinds. In addition, the housing of the transmission device and the motor itself should have good heat dissipation performance, because the motor will generate heat during long-term operation. If the heat dissipation is poor, the motor may be overheated and damaged.

[0030] As a further solution of the present invention, in step S3, the electric louver glass is sequentially installed on the fixed bracket. In order to ensure the normal operation of the electric louver glass, the gap between the bracket and the electric louver glass needs to be precisely controlled to avoid friction and resistance caused by uneven gap or over-tightening. The electric louver glass is connected to the bracket through a hinge or a bearing. When installing the electric louver glass, the installer needs to use a level or a laser measuring tool to ensure that the installation angle of each electric louver glass is correct, and the angle of the electric louver glass will not be inconsistent due to installation errors. In order to enable each electric louver glass to be accurately aligned after installation, a positioning tool or a fixing fixture is used to temporarily fix the electric louver glass to ensure that it will not be offset or deformed during the installation process. The adjustment angle range of the electric louver glass is 0° to 90°. When fixing the electric louver glass, a professional adjustment device is used to adjust each electric louver glass to a predetermined angle, and then the electric louver glass is firmly fixed by a fixing device. The fixing device is a bolt or a locking device to ensure that the electric louver glass will not loosen or deflect during long-term use.

[0031] As a further solution of the present invention, in step S4, the light sensor is installed as a sensing component in an area close to the window frame to accurately and in real time monitor the light intensity entering the room. At the same time, the light sensor should avoid being directly exposed to the shadow area of ​​the window or skylight, and also needs to avoid 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 these data back to the control system in real time.

[0032] Real-time feedback of light changes enables the control system to respond quickly and automatically adjust the angle of the electric blinds according to the different ambient light intensities, maximizing energy efficiency. When the external light intensity increases, the blinds will automatically open to allow more natural light to enter the room and reduce the need for artificial lighting; when the light intensity is too strong, the electric blinds will automatically adjust to the appropriate angle to reduce the impact of solar radiation on the indoor temperature and reduce the air conditioning load. Through this adaptive adjustment mechanism, natural light can be maximized during the day, and the electric blinds can be closed at night to reduce heat loss, thereby improving energy efficiency and reducing unnecessary energy consumption.

[0033] As a further solution of the present invention, in step S5, the power supply of the electric louver glass needs to be connected to the power grid of the building to ensure that the motor, light sensor and control system can obtain a stable power supply. After the power connection is completed, the debugging phase is entered. During the debugging process, it is first necessary to check the working status of each component, check whether the motor can start and run smoothly, and ensure that the transmission device can smoothly drive the rotation of the electric louver glass without jamming. Then, the light sensor is calibrated to ensure that the sensor can accurately and real-time sense the changes in indoor and outdoor light intensity, and transmit the data to the control system.

[0034] The technical effects and advantages of the installation method of an electric venetian blind glass of the present invention are as follows: the present invention realizes automatic adjustment of the angle of the venetian blind by accurately installing the motor, transmission device, light sensor and control system in combination with the fuzzy control algorithm, and can respond to the change of light intensity in real time, ensure the dynamic optimization of indoor lighting, reduce manual adjustment and air-conditioning load, and reduce energy consumption. In addition, the intelligent control and automatic adjustment of the system greatly improve the convenience of use, can meet the needs under different lighting conditions, and maximize the use of natural light through precise adjustment to provide an energy-saving and comfortable environment. Compared with traditional shading systems, the present invention has higher automation, flexibility and efficiency, is widely applicable to the application needs of modern intelligent buildings, and has significant energy-saving, environmental protection and comfort improvement effects.

The motor provides power to drive the rotation adjustment of the louver. The motor is closely matched with the transmission device. The function of the transmission device is to transmit the power generated by the motor to the louver through mechanical structures such as transmission shafts, gears, and pulleys. The transmission device includes a reducer, a servo motor or a stepper motor. Through these drive modules, the electric louver system can control the angle change of the louver, thereby adjusting the indoor light and temperature; the louver is made of high-strength, lightweight glass material to ensure that it has sufficient rigidity and durability during operation. The surface of the louver is coated or made of high-reflective material to further enhance its sunshade and reflection capabilities; the light The sensor monitors the changes in indoor and outdoor light intensity in real time, and feeds back these data to the control system. According to 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 louver glass to optimize the indoor lighting conditions and temperature; the control system is responsible for receiving the feedback signal from the light sensor, and determining the adjustment angle of the louver glass according to a predetermined control algorithm; the frame and bracket compatible with the building structure are customized according to the structure and size of the building to ensure that the louver glass system can be firmly installed on the glass curtain wall, and the frame material is made of high-strength aluminum alloy.

[0053] Furthermore, in step S1, the frame and bracket not only bear the weight of the entire blind glass system, but also determine the stability and long-term operation effect of the system. First, the size and installation position of the frame and bracket are determined according to the design specifications of the building windows. For large glass curtain walls, the design of the frame and bracket must calculate the load-bearing capacity of the curtain wall, and the calculation of the load-bearing capacity of the curtain wall includes the following steps:

[0054] Step Y1, calculation of horizontal wind load: According to the current national standard "Code for Loads on Building Structures" (GB50009-2012) Appendix E.5 (Table of Snow Pressure and Wind Pressure Values ​​for Cities Nationwide), it can be seen that: Based on a 50-year return period, the basic wind pressure value is 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. According to the current national standard "Code for Loads on Building Structures" (GB50009-2012), the gust coefficient β is: gz =1.7, wind pressure height variation coefficient μ z =1;

[0055] Step Y2, panel wind load calculation: According to the current national standard "Code for Loads on Building Structures" (GB50009-2012), the glass panel is regarded as a protective component that directly bears wind loads, and the shape coefficient is not reduced. Therefore, the shape coefficient of the negative pressure area of ​​the wall of this project (enclosed building) is: μ s1 =1+0.2=1.2, according to 5.3.2 of JGJ102-2003, the standard value of wind load on glass panel is W k Should not be less than 0.001N / mm 2 , so 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 wind load acting on the curtain wall, γ w is the wind load partial factor, and the wind load partial factor γ is taken according to Article 8.2.9 of the current national standard "Uniform Standard for Reliability Design of Building Structures" (GB50068-2018) w =1.5, therefore, the design value of wind load acting on the curtain wall is: W = 1.5 × 0.001 = 0.0015 N / mm 2 .

[0057] The bracket is made of aluminum alloy material, which not only has a strong load-bearing capacity, but also is corrosion-resistant and adaptable to long-term outdoor environments. When installing the bracket, a laser measuring instrument or a level is used to ensure the horizontality and verticality of the bracket to avoid unstable operation of the louver glass system due to tilted or asymmetrical installation of the bracket. The bracket is connected to the building frame by bolts. In addition, appropriate isolation pads or buffer materials need to be set between the bracket and the frame to reduce the impact caused by temperature changes, vibrations or wind.

[0058] Furthermore, in step S2, the motor is installed on a side close to the window frame and is compatible with the building structure. The motor is selected from a DC motor, an AC motor or a servo motor. When installing the motor, the axis needs to be docked with the input shaft of the transmission device to ensure the efficiency and stability of power transmission. The motor is fixed with bolts, brackets or mounting brackets to prevent vibration generated during operation from affecting the normal operation of the motor.

[0059] The function of the transmission device is to transmit the rotational power generated by the motor to the louver glass through a transmission shaft, gears, belts or chains, so as to realize the rotation adjustment of the louver glass. The transmission device is composed of a plurality of gears, bearings, pulleys, etc. The transmission ratio and friction coefficient of the gears are designed according to the size, weight and required adjustment speed of the louver glass. In addition, the housing of the transmission device and the motor itself should have good heat dissipation performance, because the motor will generate heat during long-term operation. If the heat dissipation is poor, the motor may overheat and be damaged.

[0060] Further, in the step S3, the louver glass is sequentially installed on the fixed bracket. In order to ensure the normal operation of the louver glass, the gap between the bracket and the louver glass needs to be precisely controlled to avoid friction and resistance caused by uneven gap or over-tightening. The louver glass is connected to the bracket through a hinge or a bearing. When installing the louver glass, the installer needs to use a level or a laser measuring tool to ensure that the installation angle of each louver glass is correct, and the angle of the louver glass will not be inconsistent due to installation errors. In order to enable each louver glass to be accurately aligned after installation, a positioning tool or a fixing fixture is used to temporarily fix the louver glass to ensure that it will not be offset or deformed during the installation process. The adjustment angle range of the louver glass is 0° to 90°. When fixing the louver glass, a professional adjustment device is used to adjust each louver glass to a predetermined angle, and then the louver glass is firmly fixed by a fixing device. The fixing device is a bolt or a locking device to ensure that the louver glass will not loosen or shift during long-term use.

[0061] Furthermore, in step S4, the light sensor is installed as a sensing component in an area close to the window frame to accurately and in real time monitor the light intensity entering the room. At the same time, the light sensor should avoid being directly exposed to the shadow area of ​​the window or skylight, and should also avoid excessive interference from external environmental factors (such as building shadows or weather changes). Through installation, the light sensor can continuously sense and capture changes in the intensity of natural light, and feed these data back to the control system in real time.

[0062] When the light sensor is working, it will send out an electrical signal according to the light intensity of the surrounding environment, and the control system will analyze and process the electrical signal. The control system uses a fuzzy control algorithm to dynamically adjust the electrical signal, calculate the optimal angle of the blinds, and achieve optimal light adjustment. The fuzzy control algorithm includes the following steps:

[0063] Step M1, converting the light intensity L into a fuzzy linguistic variable, wherein the linguistic variable represents different light intensity intervals. The light intensity L has the following fuzzy intervals:

[0064] Low light: below the preset light intensity threshold, indicating low light intensity;

[0065] Medium: equal to the preset light intensity threshold, indicating medium light intensity;

[0066] High light intensity (High): higher than the preset light intensity threshold, indicating a strong light intensity; the fuzzy value of the light intensity L is expressed as: L = {Low, Medium, High}, and the membership function of the fuzzy set is described by the following formula: Among them, L min is the preset minimum light intensity, L max is the preset maximum light intensity, L mid is the preset middle value of light intensity, L width is the width of the light intensity;

[0067] Step M2, the angle θ of the louver glass is also a fuzzy quantity, which is described by the following intervals:

[0068] Small angle: indicates that the blinds are completely closed to prevent direct sunlight from entering;

[0069] Medium: Indicates that the louver glass opens at a medium angle;

[0070] Large angle: indicates that the louver glass is opened at a large angle; the louver glass angle θ is fuzzy as θ = {Small, Medium, Large};

[0071] Step M3, in the defuzzification process, the final output of the louver glass angle Among them, θ d is the final angle of the louver glass after defuzzification, μ(θ i ) is the membership degree of the fuzzy output value, θ i is the corresponding angle.

[0072] Real-time feedback of light changes enables the control system to respond quickly and automatically adjust the angle of the louver glass according to the different ambient light intensities, maximizing energy efficiency. When the external light intensity increases, the louver glass will automatically open to allow more natural light to enter the room and reduce the need for artificial lighting; when the light intensity is too strong, the louver glass will automatically adjust to the appropriate angle to reduce the impact of solar radiation on the indoor temperature and reduce the air conditioning load. Through this adaptive adjustment mechanism, natural light can be maximized during the day, and the louver glass can be closed at night to reduce heat loss, thereby improving energy efficiency and reducing unnecessary energy consumption.

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

[0074] In this embodiment, see Figure 2 In the schematic diagram shown, the electric blinds are installed at the G axis / 4 axis-1 axis. Figure 3 In the schematic diagram shown, the electric shutter glass is installed at the 1 axis / G axis-E axis. Figure 4 As shown in the schematic diagram, the electric blinds are also installed at the 4th axis / E axis-G axis. Figure 5 As shown in the schematic diagram, the electric blinds are divided into three groups and controlled by a wall switch. Figure 6 In the schematic diagram shown, at the 1-axis / G-axis-E-axis, there are four compartments next to the entrance door. Figure 7 The schematic diagram shown shows two sets of electric blinds of 1-axis / G-axis and E-axis, and the wall control switch is installed on the 1-axis / G-axis column. Figure 8 The schematic diagram shown shows a three-group electric glass blind with G axis / 4 axis-1 axis, and the wall control switch is installed on the G axis / 4 axis column. Fig. 9 The schematic diagram shown shows two sets of electric blinds of 4-axis / E-axis-G-axis, and two wall hole switches are installed on the 4-axis / G-axis column.

[0075] The present invention realizes automatic adjustment of the angle of the blinds by precisely installing the motor, transmission device, light sensor and control system, combined with the fuzzy control algorithm, and can respond to changes in light intensity in real time, ensure dynamic optimization of indoor lighting, reduce manual adjustment and air conditioning load, and reduce energy consumption. In addition, the intelligent control and automatic adjustment of the system greatly improve the convenience of use, can meet the needs under different lighting conditions, and maximize the use of natural light through precise adjustment to provide an energy-saving and comfortable environment.
