Description

Technical Field

[0001] This application relates to the field of smart terminal technology, and in particular to a method, apparatus and electronic device for adjusting indoor illuminance. Background Technology

[0002] Users have certain requirements for the lighting in their homes. Typically, they increase the window area, such as by using floor-to-ceiling windows, to expand indoor lighting. However, high levels of natural light can lead to problems such as furniture being exposed to direct sunlight, excessive sunlight causing room temperature to rise, and / or high air conditioning energy consumption. Furthermore, strong direct sunlight can affect people's skin and visual health, significantly reducing human comfort.

[0003] One existing sunshade solution involves opening and closing curtains at fixed times, but this solution cannot sense the actual weather conditions, resulting in curtains being closed on cloudy days, leading to a poor user experience.

[0004] Another existing shading solution uses a fixed threshold set by a light intensity sensor to trigger shading. Specifically, the threshold of the light intensity sensor is set to a fixed value, and shading is triggered when the light intensity collected by the sensor exceeds this fixed threshold. However, the timing of shading using this solution differs from the actual indoor lighting conditions, resulting in a significant difference in the shading experience. Summary of the Invention

[0025] The terminology used in the implementation section of this application is for the purpose of explaining specific embodiments of this application only, and is not intended to limit this application.

[0026] The main purpose of shading is to ensure that the actual indoor illuminance is less than the set threshold. However, due to the presence of indoor lighting and the superposition of outdoor incident light, the light source composition is complex, making it difficult to measure the actual indoor illuminance through simple indoor illuminance collection.

[0027] Based on the above problems, this application provides a method for adjusting indoor illuminance. Outdoor illuminance is collected by an illuminance sensor and used as the basic input parameter for determining indoor illuminance. The outdoor illuminance data is combined with the window azimuth angle and the area ratio of the window to the room (also known as the "window-to-room ratio") to calculate the indoor average illuminance. The indoor average illuminance triggers a shading operation.

[0028] The indoor illuminance adjustment method provided in this application embodiment can be applied to electronic devices, wherein the electronic device can be a whole-house smart control unit, which is generally installed in the home's electrical distribution box. Alternatively, the electronic device can be any other device capable of whole-house smart control; this embodiment does not limit the form of the electronic device.

[0029] For example, Figure 1 This is a schematic diagram of the structure of an electronic device provided in one embodiment of this application, as shown below. Figure 1As shown, the electronic device 100 may include a processor 110 and a communication interface 120. Optionally, the electronic device 100 may also include a memory 130. The processor 110, the communication interface 120, and the memory 130 can communicate with each other through internal connection paths to transmit control and / or data signals. The memory 130 is used to store computer programs, and the processor 110 is used to retrieve and run the computer programs from the memory 130.

[0030] The processor 110 and memory 130 can be combined into a single processing device, but more commonly they are independent components. The processor 110 is used to execute the program code stored in the memory 130. In specific implementations, the memory 130 can be integrated into the processor 110, or it can be independent of the processor 110.

[0031] In addition, to further enhance the functionality of the electronic device 100, the electronic device 100 may also include one or more of an input unit 160 and a display unit 170.

[0032] Optionally, the electronic device 100 may further include a power supply 150 for providing power to various devices or circuits in the electronic device 100.

[0033] It should be understood that Figure 1 The processor 110 in the illustrated electronic device 100 can be a system-on-a-chip (SoC). The processor 110 may include a central processing unit (CPU) and may further include other types of processors, such as a graphics processing unit (GPU).

[0034] For ease of understanding, the following embodiments of this application will be described using the following methods: Figure 1 Taking the electronic device with the structure shown as an example, and in conjunction with the accompanying drawings and application scenarios, the method for adjusting indoor illuminance provided in this application embodiment will be specifically described.

[0035] The indoor illuminance adjustment method provided in this application uses the illuminance collected by the illuminance sensor as the basic input parameter, therefore, illuminance sensors need to be installed on the windows of the room. Specifically, as shown in Figure 2(a), two illuminance sensors need to be installed on one window to collect outdoor illuminance; as shown in Figure 2(b), if there are multiple windows facing the same direction in the room, then two illuminance sensors are installed in the same direction. Figures 2(a) to 2(b) This is a schematic diagram of the installation of a light intensity sensor provided in one embodiment of this application.

[0036] The method for adjusting indoor illuminance provided in the embodiments of this application will be described below.

[0037] Figure 3 The flowchart illustrates a method for adjusting indoor illuminance according to an embodiment of this application, as follows: Figure 3 As shown, the above-mentioned method for adjusting indoor illuminance may include:

[0038] Step 301: Electronic device 100 acquires the first illuminance value collected by the illuminance sensor. The illuminance sensor is installed on the window of the room.

[0039] Specifically, when at least two illuminance sensors are installed on windows facing the same direction in a room, the electronic device 100 can obtain the first illuminance collected by the illuminance sensors as follows: the electronic device 100 can obtain the maximum value of the illuminance collected by the at least two illuminance sensors installed on windows facing the same direction.

[0040] Step 302: The electronic device 100 determines the average illuminance in the room based on the window azimuth angle, the first illuminance, and the area ratio of the window to the room.

[0041] Step 303: The electronic device 100 opens or closes the curtains based on the average illuminance in the room and the current opening / closing degree of the curtains installed on the windows, so as to adjust the illuminance in the room.

[0042] Specifically, the electronic device 100 adjusts the room's illuminance by opening or closing the curtains based on the average illuminance in the room and the current opening / closing degree of the curtains installed on the windows. This can be achieved by: determining the illuminance range to which the average illuminance in the room belongs, and obtaining the curtain opening / closing degree range corresponding to the illuminance range; if the current opening / closing degree of the curtains is not within the curtain opening / closing degree range, then when the current opening / closing degree of the curtains is less than the minimum value of the curtain opening / closing degree range, obtaining the current time and opening the curtains based on the current time; when the current opening / closing degree of the curtains is greater than the maximum value of the curtain opening / closing degree range, closing the curtains so that the opening / closing degree of the curtains falls within the curtain opening / closing degree range.

[0043] For example, assuming the electronic device 100 determines that the average illuminance in the room belongs to the illuminance range [9000, 20000), then the electronic device 100 can obtain the curtain opening / closing range [10%, 30%] corresponding to the illuminance range. If the current opening / closing degree of the curtain is 40%, then it can be determined that the current opening / closing degree of the curtain is not within the above curtain opening / closing degree range, and the current opening / closing degree of the curtain is greater than the maximum value of the above curtain opening / closing degree range. In this case, the curtain can be closed to make the opening / closing degree of the curtain fall into the above curtain opening / closing degree range. However, if the current opening / closing degree of the curtain is 8%, then it can be determined that the current opening / closing degree of the curtain is not within the above curtain opening / closing degree range, and the current opening / closing degree of the curtain is less than the minimum value of the above curtain opening / closing degree range. In this case, the current time can be obtained, and the curtain can be opened according to the current time to make the opening / closing degree of the curtain fall into the above curtain opening / closing degree range. It should be noted that opening the curtains based on the current time can be done by: pre-setting the time period during which the curtains can be opened, for example, setting the time period during which the curtains can be opened to 7:00 to 17:00. If the current time is within the above time period, the curtains can be opened, and if the current time is not within the above time period, the curtains will not be opened.

[0044] In the above-mentioned method for adjusting indoor illuminance, after the electronic device 100 acquires the first illuminance collected by the illuminance sensor, it determines the average illuminance in the room based on the window azimuth angle, the first illuminance, and the area ratio of the window to the room. Then, based on the average illuminance in the room and the current opening / closing degree of the curtains installed on the window, the electronic device 100 opens or closes the curtains to adjust the illuminance in the room. Thus, the average illuminance in the room can be obtained through the illuminance collected by the illuminance sensor, and the opening or closing of the curtains can be controlled based on the average illuminance in the room, thereby adjusting the illuminance in the room and improving the user experience.

[0045] Figure 4 A flowchart of a method for adjusting indoor illuminance provided in another embodiment of this application is shown below. Figure 4 As shown, this application Figure 3 In the illustrated embodiment, step 302 may include:

[0046] Step 401: The electronic device 100 determines the average illuminance of direct light and diffuse light in the room based on the window azimuth angle, the first illuminance, the area ratio of the window to the room, and the diffuse reflection coefficient; and determines the average illuminance of scattered light in the room based on the window azimuth angle, the first illuminance, the area ratio of the window to the room, and the scattering coefficient.

[0047] Step 402, the electronic device 100 determines the average illuminance in the room based on the average illuminance of direct light and diffused light in the room, and the average illuminance of scattered light in the room.

[0048] Specifically, the average illuminance in the room can be the sum of the average illuminance of direct light and diffused light in the room, and the average illuminance of scattered light in the room.

[0049] Figure 5 This is a schematic diagram illustrating the effect of outdoor sunlight on indoor lighting in one embodiment of this application. See also... Figure 5 The influence of outdoor sunlight on indoor lighting can be decomposed into three parameters: direct light, outdoor diffused light, and indoor diffuse reflection. Therefore, to determine the average illuminance in a room, it is necessary to consider the influence of these three parameters on the average illuminance in the room.

[0050] 1. Average illuminance of direct and diffused light in a room

[0051] Specifically, the window direction can be set to d. win At time t, the sun's orientation is d. sun Additionally, the orientation of the plane of interest can be set to d. plain After obtaining the value I from the light intensity sensor... lux with I env Then, the solar intensity at time t can be obtained as:

[0052] I sun = (I lux - I env ) / cos(d win ,d sun (1)

[0053] In equation (1), I sun Let I be the intensity of sunlight at time t; lux The first illuminance value collected by the illuminance sensor indicates the illuminance at the sunlit location; I env I represents the illuminance in the shaded area. env Based on I lux Obtained proportionally, in practical scenarios, this proportion can typically be 0.3; cos(d win ,d sun ) is the cosine of the angle between the direction of the window and the direction of the sun, cos(d win ,d sun The value of ) can be obtained from the window azimuth angle.

[0054] Based on this, the light intensity I produced by direct light on the plane of interest can be obtained. plainwin :

[0055] I plainwin = I sun · cos(d sun ,d plain (2)

[0056] At this point, since the light cannot directly act on the entire plane, the area S corresponding to the above intensity is... plainwin It can be shown in equation (3).

[0057] S plainwin = S win * tan(d win ,d sun (3)

[0058] In equation (3), S win For the area of ​​the window; see Figure 5 S plainwin It can be Figure 5 The area of ​​the plane shown in Figure 51.

[0059] Since the light intensity produced by direct sunlight is reflected to some extent throughout the room, based on the diffuse reflection coefficient c1 = 0.3 and the theory of diffuse reflection of light, the average illuminance I of direct and diffuse light in the room can be calculated. ave1 :

[0060]

[0061] In equation (4), S room The area of ​​the room. The ratio of window area to room area. The value of is generally in Between, cos(d) win ,d sun ) is the cosine of the angle between the direction of the window and the direction of the sun, cos(d win ,d sun The value of f(S) can be obtained from the window azimuth angle; plainwin S room The ratio of the area of ​​the light spot formed by direct sunlight entering the room through the window to the area of ​​the room.

[0062] 2. Average illuminance of diffused light in the room

[0063] Scattered light contributes to indoor lighting in a diffused manner; therefore, the average illuminance I of scattered light in a room is... ave2 It can be calculated according to formula (5).

[0064]

[0065] In equation (5), c2 is the scattering coefficient, and the value of c2 can be 0.4; f(S room S win () represents the ratio of room area to window area.

[0066] After obtaining the average illuminance of direct light and diffuse light in the room, and the average illuminance of scattered light in the room, the electronic device 100 determines the average illuminance in the room based on the average illuminance of direct light and diffuse light in the room, and the average illuminance of scattered light in the room, as shown in Equation (6).

[0067]

[0069] Step 601: Electronic device 100 acquires the second illuminance collected by illuminance sensor within a predetermined time period.

[0070] The aforementioned predetermined time period can be a period of time prior to the current time, and can be set by the user in the specific implementation. This embodiment does not limit the aforementioned predetermined time period.

[0071] Step 602: The electronic device 100 filters the second illuminance to obtain the third illuminance and acquires the acquisition time of the third illuminance.

[0072] In some examples, the electronic device 100 can filter the maximum illuminance from the second illuminance as the third illuminance and obtain the acquisition time of the third illuminance. Of course, this is only one implementation of this embodiment and does not constitute a limitation on this embodiment. This embodiment does not limit the method of filtering to obtain the third illuminance.

[0073] Step 603: The electronic device 100 determines the window azimuth angle based on the third illuminance, the time of the third illuminance acquisition, the latitude and longitude of the room's location, and the time zone to which the latitude and longitude belong.

[0074] In this embodiment, the aforementioned window azimuth angle is the solar azimuth angle. In specific implementation, the electronic device 100 can calculate the aforementioned window azimuth angle using the ecliptic coordinate system in the celestial coordinate system based on the third illuminance, the time of the third illuminance acquisition, the latitude and longitude of the location of the aforementioned room, and the time zone to which the aforementioned latitude and longitude belong.
