DETAILED DESCRIPTION

[0024] In order to better understand the above technical solutions, the above technical solutions will be described in detail in combination with the drawings of the specification and the specific embodiments.

[0025] Embodiment 1:

[0026] Embodiment 1 provides a smart curtain wall, referring to Figures 1 to 5 , comprising: a curtain wall body, the curtain wall body comprising an outer high light transmission glass 100 and an inner high light transmission glass 300, a containing space is formed between the outer high light transmission glass 100 and the inner high light transmission glass 300, a plurality of adjustable main bodies are arranged in the containing space, the adjustable main body comprises at least two switchable adjustment surfaces, the first adjustment surface 211 and the second adjustment surface 212 of the adjustable main body have different reflectivity.

[0027] The light transmittance of the outer high light transmittance glass 100 and the inner high light transmittance glass 300 is 95% to 99%; the first adjusting surface 211 is a mirror surface glass, and the reflectivity is 25% to 30%; and the second adjusting surface 212 is a frosted glass, and the reflectivity is 3% to 8%.

[0028] In a preferred scheme, the adjustable body can further include adjusting surfaces for adjusting purposes other than the reflectivity. For example, the third adjusting surface 213 of the adjustable body is a photovoltaic panel, and the fourth adjusting surface 214 of the adjustable body is an LED panel.

[0029] In addition, the smart curtain wall can further include an adjusting system 220, an illumination detection system, a control system, an electricity storage device, and a backup power supply. The following describes the components.

[0030] The adjusting system 220 is used to control the adjustable body to switch the adjusting surfaces.

[0031] For example, the adjustable body includes an adjustable base 230 and a rotating column 210 mounted on the adjustable base 230, the adjustable base 230 is provided with threaded holes, and at least two switchable adjusting surfaces are mounted on the rotating column 210; the adjusting system 220 includes a translation motor 221, a rotating motor, and a threaded rod 222; the threaded rod 222 passes through the threaded holes of the adjustable bases 230, and the translation motor 221 is connected with the threaded rod 222; the translation motor 221 is used to drive the adjustable bases 230 to translate, so as to leave a rotating space between adjacent adjustable bases 230, or to drive the adjustable bases 230 to return to the initial position; and the rotating motor is used to drive the adjustable bases 230 to rotate, so as to switch the adjusting surfaces.

[0032] Taking the rotating column 210 in the adjustable body as an example, the curtain wall body is two layers of high light transmittance glass, and a plurality of adjustable quadrangular prisms are placed side by side between the two layers of glass. By placing the adjusting system 220 and the adjustable base 230 in the external base 400, the appearance of the building can be maintained. It should be noted that, Figure 1 The column 500 in the figure is only used to indicate the position of the curtain wall. In order to be beautiful, when not rotating, all the adjustable quadrangular prisms are closely attached without leaving gaps, as shown in Figure 2 That is, when closely attached, the left side or the right side of the whole formed by all the adjustable quadrangular prisms, or the left side and the right side, leaves enough space for translation operation. When rotating, the translation motor 221 is used to drive all the adjustable quadrangular prisms to translate, so as to leave enough rotating radius, and after reaching the position, the rotating motor in the adjustable base 230 drives the adjustable quadrangular prisms to rotate, as shown in Figure 3 .

[0033] Wherein, the threaded rod 222 passes through a plurality of adjustable bases 230, each adjustable base 230 has a corresponding thread. Because when translating, the displacement of the adjustable base 230 far from the translation motor 221 is large, and the displacement of the adjustable base 230 near the translation motor 221 is small, the corresponding base thread number on the threaded rod 222 is reduced by the same proportion, but the total length is unchanged, see Figure 4 This can ensure that when the translation motor 221 rotates forward, the gap between each adjustable quadrilateral prism is the same and can just meet the rotation radius. After rotation, the translation motor 221 reverses, and the plurality of adjustable quadrilateral prisms returns to the initial position, that is, to the original position.

[0034] When the rotating column 210 in the adjustable body is an adjustable quadrilateral prism, the structure can be seen from Figure 5 The four surfaces of the quadrilateral prism are respectively four different materials: mirror glass (as the first adjustment surface 211), frosted glass (as the second adjustment surface 212), photovoltaic panel (as the third adjustment surface 213), and LED panel (as the fourth adjustment surface 214). The center of the adjustable quadrilateral prism is hollow, and the cables of the photovoltaic panel and the LED panel are led out through the center of the adjustable quadrilateral prism.

[0035] Wherein, the light intensity detection system is used to obtain light intensity information, and the control system is used to control the adjustment system 220 to perform the switching operation of the adjustment surface according to the light intensity information.

[0036] The photovoltaic panel is used to convert light energy into electrical energy to charge the power storage device. The power storage device is used to store electrical energy and power at least one of the adjustment system 220, the control system, and the LED panel.

[0037] The backup power supply is used to provide power for the intelligent curtain when the power of the power storage device is lower than the preset power and the current light intensity is lower than the preset light intensity.

[0038] For example, the light intensity detection system comprises a light intensity transmitter, which is arranged at a place with large light intensity on the top floor of the building, and can proportionally change the light intensity into an analog signal. The control system comprises a PLC (Programmable Logic Controller), a relay group, an LED panel controller, etc. The light intensity transmitter is connected with the PLC. The photovoltaic panel and the power storage device jointly constitute a photovoltaic and power storage system, which comprises a photovoltaic panel, a current combiner box, an inverter, a storage battery, etc. The cables of all the photovoltaic panels are led out through the center of the adjustable quadrangular prism to the current combiner box, and are divided into two branches. One branch is used to charge the storage battery, and the storage battery is responsible for powering the translation motor 221, the rotation motor, the LED panel, and part or all of the relays. The other branch enters the inverter to become an AC 220V, and is used to power the PLC. When the power of the storage battery is low, an output signal is sent to the PLC to control the adjustable quadrangular prism to rotate to the photovoltaic panel for charging.

[0039] In application, the light intensity analog signal is connected with the PLC. When the light intensity is high (for example, higher than a preset light intensity threshold), the PLC outputs a translation signal, the adjustable quadrangular prism in the curtain wall is translated to leave a sufficient rotation radius, the PLC outputs a rotation signal after the adjustable quadrangular prism is in place, the rotation motor rotates the adjustable quadrangular prism to the frosted glass surface, and the translation motor 221 operates to restore the adjustable quadrangular prism to the close state after the rotation is in place. When the light intensity is low (for example, lower than a preset light intensity threshold), the translation motor 221 and the rotation motor control the adjustable quadrangular prism to rotate the mirror glass to the outside under the control of the PLC to ensure the aesthetics of the curtain wall. When the power of the power storage device is low (for example, less than 20%) and there is a certain light intensity, the PLC controls the adjustable quadrangular prism to rotate to the photovoltaic panel to charge the power storage device. If the power is insufficient and the light intensity is insufficient, the standby power source is connected. After sunset, if there is no advertising plan, the LED panel does not need to be rotated to the outside; if there is an advertising plan, the pattern can be input into the LED controller in advance, and the LED panel is rotated to the outside to display the advertising pattern after sunset.

[0040] Embodiment 2:

[0041] Embodiment 2 provides a control method of the intelligent curtain wall as described in Embodiment 1. Embodiment 2 switches the multiple adjustment surfaces of the adjustable main body according to at least one of light intensity information, power information, and application plan information.

[0042] The application can reduce light pollution while ensuring the beauty of the curtain wall by switching the adjusting surface with different reflectivity under different environmental conditions. Furthermore, the application can also be intelligently adjusted according to other purposes (such as green environmental protection, advertisement delivery, etc.) other than the purpose of adjusting reflectivity.

[0043] Taking the case that the adjustable body includes four adjusting surfaces, the first adjusting surface is a mirror glass with a reflectivity of 25% to 30%, the second adjusting surface is frosted glass with a reflectivity of 3% to 8%, the third adjusting surface is a photovoltaic panel, and the fourth adjusting surface is an LED panel, the control method of the intelligent curtain wall is described.

[0044] When the light intensity is low (for example, overcast or rainy days), the first adjusting surface is switched to ensure the beauty of the curtain wall.

[0045] When the light intensity is high (for example, strong light weather), the second adjusting surface is switched to effectively reduce light pollution.

[0046] When the power of the intelligent curtain wall is low, the third adjusting surface is switched to charge, playing a role of green environmental protection.

[0047] When there is an application plan, the fourth adjusting surface is switched to form a giant LED panel to deliver advertisements, achieving a profit effect.

[0048] Since the control method of the intelligent curtain wall provided by embodiment 2 corresponds to the functions of each device in the intelligent curtain wall provided by embodiment 1, embodiment 2 can be understood by referring to the description of embodiment 1, which will not be repeated here.

[0049] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the application and are not limiting. Although the application has been described in detail with reference to the examples, those skilled in the art should understand that the technical solutions of the application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the application, which should be covered in the scope of the claims of the application.
