[0002] Office buildings, libraries, and educational buildings, which require high lighting requirements, often require shading to adjust the comfort level of natural lighting. Natural lighting comfort includes comfortable illumination, avoiding glare near windows and at the viewpoint, and ensuring a suitable view out the windows. Furthermore, appropriate shading can regulate solar radiation, reduce cooling energy consumption in summer, and balance the conflict between glare and the increasing demand for solar radiation in winter.

[0005] The shortcomings of existing technologies are: ① There is no complete intelligent shading technology for adjusting indoor environmental parameters; ② Existing shading inventions only consider the blocking of solar radiation and rarely consider the utilization of solar radiation; ③ Existing shading inventions do not consider the contradiction between light environment comfort and solar radiation demand; ④ Existing shading forms with dynamic control technology such as blinds and roller blinds have a single movement form and cannot meet the dynamic needs of the indoor light and heat environment according to environmental changes. Summary of the Invention

[0009] Furthermore, the lighting blades are made of opaque rigid materials such as polymers and metal composite materials, and the surface reflectivity of the rigid material is greater than 0.7.

[0010] Furthermore, the side panel 1, the side panel 2 and the side panel 3 are all made of metal materials, and the connecting rod 1 and the connecting rod 2 are composed of one-way hinges or bearings.

[0011] Furthermore, the control component includes a slide rail group, a controller, a horizontal illuminance monitoring sensor probe and a temperature monitoring sensor probe. Some of the horizontal illuminance detection sensor probes and all the temperature detection sensor probes are arranged outside the exterior window to detect the outdoor light and temperature, and some of the horizontal illuminance detection sensor probes are arranged indoors to detect the indoor light.

[0012] The present invention also provides a control method for an energy-saving and light-comfort-oriented intelligent external sunshade device, comprising the following steps:

[0013] S1: Control logic: Divide the fully expanded width L of the daylighting blades into 10 equal distances, with each segment marked as a scale. Each time the side panel 2 moves to a scale position, it enters a sunshade state. The movement of the side panel 2 can be constrained by the slide rail assembly. The scale only considers L0 of each group of daylighting modules, and each group of sunshade components moves uniformly.

Set the shading limit temperatures as TLmax and TLmin, and the shading control temperatures as TCmax and TCmin. The calculation method is the human thermal comfort model:

[0019] C=Td-0.55*(1-RH)*(Td-58) (Formula 1)

[0020] In the formula: C value is the human comfort index; Td is the dry bulb temperature, unit is; RH is the relative humidity ℉, unit is %.

[0021] The conversion formula between Fahrenheit and Celsius is:

[0022] Td(℉)=Td(℃)*9 / 5+32 (Formula 2)

[0023] C value reference table:

[0024] When the C value exceeds 90, people will feel extremely hot and uncomfortable, and the corresponding calculated temperature Td is TLmax;

[0025] When the C value exceeds 79, people will feel hot or relatively hot, and some people will feel hot and uncomfortable. The corresponding calculated temperature Td is TCmax;

[0026] When the C value is lower than 60, people will feel cool or cold, and some people will feel uncomfortable. The corresponding calculated temperature Td is TCmin;

[0027] When the C value is lower than 40, people will feel cold and uncomfortable, and the corresponding calculated temperature Td is TLmin.

[0028] Specifically, S32 is executed once per hour. The algorithm for executing once per hour in S32 includes the following steps:

[0029] S321: Calculate the local minimum opening illuminance, calculate the local shading limit temperatures TLmax and TLmin, and calculate the local shading control temperatures TCmax and TCmin;

[0030] S322: If the outdoor horizontal illuminance U0 is ≥ 15000 lx, the sunshade component is operated; otherwise, it is completely retracted and closed;

[0031] S323: Assume that the indoor temperature is T1. If T1>TCmax, the daylighting module is fully extended and adjusted to scale 9. If T1<TCmin, the sunshade component is fully retracted and closed. If TCmin≤T1≤TCmax, the daylighting module is in operation.

[0032] S324: Assume that the outdoor temperature is T0. When the daylighting module is in operation, if T0>TLmax, the daylighting module is fully extended and adjusted to scale 9; if T0<TLmin, the daylighting module is in operation and the anti-glare module is closed and retracted; if TLmin≤T0≤TLmax, both the daylighting module and the anti-glare module are in operation;

[0033] S325: Evenly arrange at least four illuminance measurement points near the windows and deep working surfaces in the room. When both the daylighting module and the anti-glare module are in operation, measure and count the illuminance at each point. Let the number of measurement points with illuminance below 300lx be Q1, and the number of measurement points with illuminance above 2000lx be Q2. If Q1>Q2, then adjust the daylighting module down by one scale; if Q1<Q2, then adjust the daylighting module up by one scale; until Q1=Q2, the sunshade component will maintain this state until the next hour;

When both the daylighting module and the anti-glare module are running, if the person at the workstation feels uncomfortable with the glare, he or she can click the control switch, and the daylighting module will be adjusted up one scale and maintained in this state until the next hour.

[0035] The beneficial effects of the present invention are:

DETAILED DESCRIPTION

[0050] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0051] In this embodiment, if Figures 1 to 7 As shown, an energy-saving and light-comfort-oriented intelligent external sunshade device comprises a sunshade component 1 arranged on the surface of an external window, the sunshade component 1 comprises at least two sunshade units 2 arranged in sequence from left to right, the sunshade unit 2 comprises a lighting module 21 for adjusting indoor direct sunlight and diffuse light and an anti-glare module 22 for anti-glare for human eyes, the lighting module 21 comprises a side panel 1 3, a side panel 2 4 and a plurality of lighting blades 5 evenly arranged from top to bottom, the side panel 1 3 and the side panel 2 4 are arranged at intervals on the outside of the external window, and the side panel 1 3 is fixed to the outside of the external window, the side panel 2 4 is slidably connected to the outside of the external window, and a plurality of lighting blades 5 are arranged between the side panel 1 3 and the side panel 2 4, the anti-glare module 22 comprises a side panel 3 6 and two groups of lighting blades 5, the side panel 3 6 is arranged on the side of the side panel 2 4 away from the side panel 1 3, the two groups of lighting blades 5 are arranged between the side panel 2 4 and the side panel 3 6, and there is a The sunshade structure 1 has two sides, the first side, the second side, the second side, and the third side are connected to each other, and the sunshade structure 1 has two sides, the second side is ...

[0052] It is worth noting that when multiple sunshade units 2 are arranged side by side outside the exterior window, the side panel one and side panel three 6 between the two sunshade units 2 are fixedly connected. In order to reduce material loss, the side panel one 3 and side panel three 6 between the two sunshade units 2 can be side panels.

[0053] The control assembly includes a rail assembly, a controller, horizontal illuminance monitoring sensor probes, and temperature monitoring sensor probes. Some of the horizontal illuminance detection sensor probes and all of the temperature detection sensor probes are arranged outside the exterior window to detect outdoor light and temperature, while some of the horizontal illuminance detection sensor probes are arranged indoors to detect indoor light. The rail assembly, horizontal illuminance detection sensor probes, and temperature detection sensor probes are all electrically connected to the controller. The rail assembly is disposed at the bottom of the sunshade member 1 and is fixedly connected to the second side panel 4. The controller drives the rail assembly to move, thereby driving the second side panel 4 to move, thereby achieving alternating folding of the lighting module 21 and the anti-glare module 22, so as to achieve a change in the sunshade state through the relative movement of the second side panel 4. A small number of horizontal illuminance monitoring sensor probes and temperature monitoring sensor probes are arranged in the outdoor open space for calculating the outdoor horizontal illuminance average value and the outdoor temperature average value. A small number of horizontal illuminance monitoring sensor probes and temperature monitoring sensor probes are evenly arranged on the indoor horizontal working surface for calculating the indoor horizontal illuminance average value.

[0054] When working, the sunshade component 1 is installed as a whole on the outer window of the facade, and the distance between the sunshade component 1 and the outer window must be greater than the sunshade component 1-lighting blade 5, wherein each light-collecting blade 5 is composed of four rigid plates, such as Figure 7As shown, the two plates 1 51 are driven plates, and the two plates 2 52 are active plates. The AH and EF edges of the two plates 1 51 and the two plates 2 52 are connected to the left side plate 3 and the side plate 2 4 respectively to realize active movement. The two plates 1 51 and the two plates 2 52 are connected to each other through two connecting rods 2 54 respectively to realize following movement. The two plates 1 51 are connected through the connecting rod 1 53 to realize motion constraint. The height h of the lighting blade 5 should be above 200mm to ensure the ability to adjust the illumination. The width L should be greater than 4h and should not be greater than 8h. Excessive force is not conducive to the stability of rigid materials, and L should be less than 1 / 4 of the width of the outer window. Each outer window requires at least two groups of sunshade units 2, and the side panel 2 4 is controlled to move by the control component, so as to achieve the change of the sunshade state by adjusting the distance between the left side panel 3 and the side panel 2 4. The distance between the left side panel 3 and the side panel 2 4 is L0, so that the sunshade component 1 can realize the change of the area of ​​the component on the outer window surface through the folding and unfolding movement, and can be fully unfolded or folded. When the lighting module 21 is unfolded, the anti-glare module 22 is retracted, and vice versa, the anti-glare module 22 is unfolded, and the folding and unfolding movement of the sunshade component 1 will produce a folding direction, which is consistent with the folding direction for the front side, and opposite to the folding direction for the back side. When the lighting module 21 starts to retract, the opened outer window area will receive outdoor natural light while also causing glare. When the height of the outer window sill is lower than 1200mm, it is necessary to set the lighting blade 5 at the lower part of the anti-glare module 22 to prevent glare near the window; when the upper edge of the outer window is higher than 2400mm, it is necessary to set the reverse lighting blade 5 to prevent glare at the human viewpoint;

[0055] In order to avoid the phenomenon that the light-collecting blades 5 cannot be folded, an error should be reserved to prevent the connection of the light-collecting blades 5 from being deformed when the light-collecting module 21 shrinks excessively, thereby affecting the life of the component. Therefore, the sunshade component 1 cannot be completely folded, and the minimum folded state is L0≥1 / 10L; the present invention can dynamically adjust the sunshade form according to indoor and outdoor light and heat environment parameters and solar radiation conditions, thereby improving indoor light comfort, reducing summer cooling energy consumption, and solving the contradiction between light comfort requirements and winter solar radiation utilization requirements of buildings. The foldable structure of the sunshade component 1 has a high degree of freedom, multiple dimensions of change, and a large folding area ratio, which can better adapt to changing climatic conditions, and the design of the sunshade structure fully considers the aesthetics and the user's needs for the view outside the window, thereby better responding to the user's dynamic needs for the indoor light and heat environment, not only improving comfort, but also having the effect of energy saving and emission reduction.

[0056] Specifically, the side panel 1 3 , the side panel 2 4 and the side panel 3 6 are all perpendicular and parallel to the outer window surface, so that the height of the sunshade component 1 is consistent with the height of the outer window, and the module width is determined according to the outer window width.

[0057] Specifically, the lighting blades 5 are made of opaque rigid materials such as polymers and metal composite materials, and the surface reflectivity of the rigid material is greater than 0.7 to ensure the strength and reflectivity of the lighting blades 5 to sunlight and avoid deformation of the lighting blades 5 when folded.

[0058] Specifically, the side panel 1 3, the side panel 2 4 and the side panel 3 6 are all made of metal materials, and the connecting rod 1 53 and the connecting rod 2 54 are composed of one-way hinges or bearings to improve the strength of the left side panel 3 and the side panel 2 4, thereby ensuring the stability of the light-collecting blade 5 when folded. In addition, the connecting rod 1 53 and the connecting rod set by the hinges or bearings can make the folding between the panel 1 51 and the panel 2 52 smooth, thereby avoiding the phenomenon of bending and breaking of the light-collecting blade 5 when folded.

[0059] like Figure 8-Figure 9 As shown, the present invention also provides a control method for an energy-saving and light-comfort-oriented intelligent external sunshade device, comprising the following steps:

[0060] S1: Control logic: Divide the fully extended width L of the daylighting blades 5 into 10 equal distances, with each section marked as a scale. Each time the side panel 2 4 moves to a scale position, it is in a sunshade state. The movement of the side panel 2 4 can be constrained by the slide rail assembly. The scale only considers L0 of each group of daylighting modules 21, and each group of sunshade components 1 moves uniformly, as shown in the following table:

[0061] L0 L0=1 / 10L L0=2 / 10L L0=3 / 10L L0=4 / 10L L0=5 / 10L scale 1 2 3 4 5 L0 L0=6 / 10L L0=7 / 10L L0=8 / 10L L0=9 / 10L scale 6 7 8 9

[0062] S2: Measurement point arrangement: Arrange a small number of horizontal illuminance monitoring sensor probes and temperature monitoring sensor probes (at least two groups) in an open outdoor space, and calculate the outdoor horizontal illuminance average value and temperature average value;

[0063] S3: Evenly arrange a small number of horizontal illuminance monitoring sensor probes and temperature monitoring sensor probes (at least four groups) on the indoor horizontal working surface and calculate the average indoor horizontal illuminance.

[0064] Specifically, the calculation method in S3 includes the following steps:

[0065] S31: Set the minimum opening illumination according to the illumination standard value of the light climate zone where the city is located;

[0066] S32: Calculate the local maximum and minimum shading limit temperatures and shading control temperatures based on the city's average summer and winter temperatures. Set the shading limit temperatures as TLmax and TLmin, and the shading control temperatures as TCmax and TCmin. The calculation method is the human thermal comfort model:

[0067] C=Td-0.55*(1-RH)*(Td-58) (Formula 1)

[0068] In the formula: C value is the human comfort index; Td is the dry bulb temperature, unit is; RH is the relative humidity ℉, unit is %.

[0069] The conversion formula between Fahrenheit and Celsius is:

[0070] Td(℉)=Td(℃)*9 / 5+32 (Formula 2)

[0071] C value reference table:

[0072] When the C value exceeds 90, people will feel extremely hot and uncomfortable, and the corresponding calculated temperature Td is TLmax;

[0073] When the C value exceeds 79, people will feel hot or relatively hot, and some people will feel hot and uncomfortable. The corresponding calculated temperature Td is TCmax;

[0074] When the C value is lower than 60, people will feel cool or cold, and some people will feel uncomfortable. The corresponding calculated temperature Td is TCmin;

[0075] When the C value is lower than 40, people will feel cold and uncomfortable, and the corresponding calculated temperature Td is TLmin.

[0076] Specifically, S32 is executed once per hour. The algorithm for executing once per hour in S32 includes the following steps:

[0077] S321: Calculate the local minimum opening illuminance, calculate the local shading limit temperatures TLmax and TLmin, and calculate the local shading control temperatures TCmax and TCmin;

[0078] S322: If the outdoor horizontal illuminance U0 is ≥ 15000 lx, the sunshade member 1 is operated; otherwise, it is completely retracted and closed;

[0079] S323: Assume that the indoor temperature is T1. If T1>TCmax, the lighting module 21 is fully extended and adjusted to scale 9. If T1<TCmin, the sunshade member 1 is fully retracted and closed. If TCmin≤T1≤TCmax, the lighting module 21 is in operation.

[0080] S324: Assuming the outdoor temperature is T0, when the daylighting module 21 is in operation, if T0>TLmax, the daylighting module 21 is fully extended and adjusted to scale 9; if T0<TLmin, the daylighting module 21 is in operation and the anti-glare module 22 is closed and retracted; if TLmin≤T0≤TLmax, both the daylighting module 21 and the anti-glare module 22 are in operation;

[0081] S325: Evenly arrange at least four illuminance measurement points near the windows and deep working surfaces in the room. When both the daylighting module 21 and the anti-glare module 22 are in operation, measure and count the illuminance at each point. Let Q1 be the number of measurement points where the illuminance is below 300 lx, and Q2 be the number of measurement points where the illuminance is above 2000 lx. If Q1>Q2, then adjust the daylighting module 21 down by one scale; if Q1<Q2, then adjust the daylighting module 21 up by one scale. Until Q1=Q2, the sunshade component 1 will maintain this state until the next hour.

[0082] S326: A glare controller is set at each person's workstation. When both the daylighting module 21 and the anti-glare module 22 are running, if the person at the workstation feels uncomfortable with the glare, he or she can click the control switch, and the daylighting module 21 will be adjusted up by one scale and maintained in this state until the next hour.
