Method, device and electronic equipment for adjusting indoor light intensity

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on September 21, 2023, with application number 202311228279.4 and application name “Method, device and electronic device for adjusting indoor light intensity”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The embodiments of the present application relate to the field of smart terminal technology, and in particular to a method, device, and electronic device for adjusting indoor light intensity. Background Art

[0003] Users have certain requirements for daylighting in their homes. Typically, they increase window size, such as with floor-to-ceiling windows, to increase indoor lighting. However, this increased daylighting can expose furniture to direct sunlight, leading to elevated room temperatures and / or increased air conditioning energy consumption. Furthermore, strong direct sunlight can affect skin and visual health, significantly reducing comfort.

[0004] An existing sunshade solution is to open and close curtains at fixed times, but this solution cannot sense the actual weather conditions. There are cases where the curtains are closed on cloudy days, which results in a poor user experience.

[0005] Another existing shading solution uses a fixed light sensor threshold to trigger shading. Specifically, the light sensor threshold is set to a fixed threshold. When the light intensity detected by the light sensor exceeds this fixed threshold, the shading operation is triggered. However, the shading timing of this solution differs from the actual indoor lighting conditions, resulting in a significant difference in the shading experience.

[0027] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application.

[0028] The main purpose of sun 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 structure is complex, making it difficult to measure the actual indoor illuminance through simple indoor illuminance collection.

[0029] Based on the above problems, an embodiment of the present application provides a method for adjusting indoor light illumination, in which outdoor light illumination is collected by a light sensor and used as the basic input parameter for determining indoor light illumination. The outdoor light illumination data is combined with the window azimuth and the area ratio of the window to the room (also known as the "window-to-room ratio") to calculate the average indoor illumination, and the shading operation is triggered by the average indoor illumination.

[0030] The indoor light adjustment method provided in the embodiments of the present application can be applied to electronic devices, wherein the electronic device can be a whole-house smart host, which can generally be installed in a household's power distribution box. Furthermore, the electronic device can also be other devices capable of whole-house smart control, and this embodiment does not limit the form of the electronic device.

[0031] For example, FIG1 is a schematic diagram of the structure of an electronic device provided by one embodiment of the present application. As shown in FIG1 , the electronic device 100 may include a processor 110 and a communication interface 120. Optionally, the electronic device 100 may further include a memory 130. The processor 110, the communication interface 120, and the memory 130 may communicate with each other via an internal connection path to transmit control and / or data signals. The memory 130 is used to store computer programs, and the processor 110 is used to call and execute the computer programs from the memory 130.

[0032] The processor 110 and the memory 130 may be combined into a processing device, or more commonly, they are independent components. The processor 110 is used to execute program codes stored in the memory 130. In a specific implementation, the memory 130 may also be integrated into the processor 110, or independent of the processor 110.

[0033] In addition, in order to make the functions of the electronic device 100 more complete, the electronic device 100 may further include one or more of an input unit 160 and a display unit 170 .

[0034] 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 .

[0035] It should be understood that the processor 110 in the electronic device 100 shown in FIG1 may be a system on a chip (SOC), which may include a central processing unit (CPU) and may further include other types of processors, such as a graphics processing unit (GPU).

[0036] For ease of understanding, the following embodiments of the present application will take an electronic device having the structure shown in FIG1 as an example, and combine the accompanying drawings and application scenarios to specifically explain the indoor light intensity adjustment method provided in the embodiments of the present application.

[0037] The indoor light adjustment method provided in an embodiment of the present application uses the light collected by the light sensor as the basic input parameter, so it is necessary to install a light sensor on the window of the room. Specifically, as shown in Figure 2(a), two light sensors need to be installed on one window to collect outdoor light. As shown in Figure 2(b), if there are multiple windows in the same direction in the room, a total of two light sensors are installed in the same direction. Figures 2(a) and 2(b) are schematic diagrams of the installation of the light sensor provided in an embodiment of the present application.

[0038] The following describes a method for adjusting indoor light intensity provided in an embodiment of the present application.

[0039] FIG3 is a flow chart of a method for adjusting indoor light intensity according to an embodiment of the present application. As shown in FIG3 , the method for adjusting indoor light intensity may include:

[0040] In step 301, the electronic device 100 obtains a first illuminance collected by a illuminance sensor, wherein the illuminance sensor is installed on a window of a room.

[0041] Specifically, when at least two light sensors are installed on windows facing the same direction in a room, the electronic device 100 may obtain the first light intensity collected by the light sensors by: the electronic device 100 obtains the maximum value of the light intensity collected by the at least two light sensors installed on windows facing the same direction.

[0042] In step 302 , the electronic device 100 determines the average illuminance in the room according to the window azimuth, the first illuminance, and the area ratio of the window to the room.

[0043] In step 303 , the electronic device 100 opens or closes the curtains according to the average illumination in the room and the current opening / closing degree of the curtains installed on the windows to adjust the illumination in the room.

[0044] Specifically, the electronic device 100 opens or closes the curtains installed on the windows according to the average illumination in the room and the current opening and closing degree of the curtains to adjust the light illumination in the room. This can be as follows: the electronic device 100 determines the illumination interval to which the average illumination in the room belongs, and obtains the curtain opening and closing degree interval corresponding to the illumination interval; if the current opening and closing degree of the curtains is not within the curtain opening and closing degree interval, when the current opening and closing degree of the curtains is less than the minimum value of the curtain opening and closing degree interval, obtains the current time, and opens the curtains according to the current time; when the current opening and closing degree of the curtains is greater than the maximum value of the curtain opening and closing degree interval, closes the curtains so that the opening and closing degree of the curtains falls within the curtain opening and closing degree interval.

[0045] For example, assuming that the electronic device 100 determines that the average illuminance in the room belongs to an illumination interval of [9000, 20000), the electronic device 100 can obtain the curtain opening and closing interval [10%, 30%] corresponding to the illumination interval. If the current opening and closing degree of the curtain is 40%, it can be determined that the current opening and closing degree of the curtain is not within the curtain opening and closing interval and is greater than the maximum value of the curtain opening and closing interval. In this case, the curtain can be closed to bring the curtain opening and closing degree within the curtain opening and closing interval. If the current opening and closing degree of the curtain is 8%, it can be determined that the current opening and closing degree of the curtain is not within the curtain opening and closing interval and is less than the minimum value of the curtain opening and closing interval. In this case, the current time can be obtained and the curtain can be opened based on the current time to bring the curtain opening and closing degree within the curtain opening and closing interval. It should be noted that the curtains can be opened according to the current time by pre-setting the time period during which the curtains are allowed to be opened. For example, the time period during which the curtains are allowed to be opened can be set to 7:00-17:00. If the current time is within the time period, the curtains can be opened, but if the current time is not within the time period, the curtains will not be opened.

[0046] In the above-mentioned method for adjusting indoor light intensity, after the electronic device 100 obtains the first light intensity collected by the light intensity sensor, it determines the average light intensity in the room based on the window azimuth, the first light intensity, and the area ratio of the window to the room. Then, the electronic device 100 opens or closes the curtains based on the average light intensity in the room and the current opening and closing degree of the curtains installed on the window to adjust the light intensity in the room. In this way, the average light intensity in the room can be obtained through the light intensity collected by the light intensity sensor, and then the opening or closing of the curtains can be controlled based on the average light intensity in the room, thereby adjusting the light intensity in the room and improving the user experience.

[0047] FIG4 is a flow chart of a method for adjusting indoor light intensity according to another embodiment of the present application. As shown in FIG4 , in the embodiment shown in FIG3 of the present application, step 302 may include:

[0048] In step 401, the electronic device 100 determines the average illuminance of direct light and diffusely reflected light in the room based on the window azimuth, 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, the first illuminance, the area ratio of the window to the room, and the scattering coefficient.

[0049] In step 402 , the electronic device 100 determines an average illumination in the room according to the average illumination of the direct light and the diffusely reflected light in the room, and the average illumination of the scattered light in the room.

[0050] Specifically, the average illuminance in the room may be the sum of the average illuminance of direct light and diffusely reflected light in the room, and the average illuminance of the scattered light in the room.

[0051] Figure 5 is a schematic diagram of the impact of outdoor sunlight on the lighting in the room provided by an embodiment of the present application. Referring to Figure 5, the impact of outdoor sunlight on the lighting in the room can be decomposed into three parameters: direct light, outdoor scattered light and indoor light spot diffuse reflection. Therefore, to determine the average illumination in the room, it is necessary to consider the impact of these three parameters: direct light, scattered light and diffuse reflection light on the average illumination in the room.

[0052] 1. Average illumination of direct light and diffuse light in the room

[0053] Specifically, the direction of the window can be set to d win , and at time t, the direction of the sun is d sun In addition, the orientation of the plane of interest can be set to d plain After obtaining the value of the light sensor I lux with I env Afterwards, the solar intensity at time t can be obtained as:

[0054] I sun =(I lux -I env ) / cos(d win ,d sun ) (1)

[0055] In formula (1), I sun is the solar intensity at time t; I lux I is the first illuminance collected by the illuminance sensor, indicating the illuminance in the sunny area; env is the illuminance in the shade, I env Can be based on I lux Obtained in proportion, in actual scenarios, the typical value of this ratio can be: 0.3; cos(d win ,d sun ) is the cosine of the angle between the window direction and the sun direction, cos(d win ,d sun ) can be obtained based on the window azimuth.

[0056] On this basis, the light intensity I generated by the direct light on the plane of interest can be obtained. plainwin :

[0057] I plainwin =I sun ·cos(d sun ,d plain ) (2)

[0058] At this time, since the light cannot directly act on all planes, the area size S corresponding to the above intensity plainwin It can be shown as formula (3).

[0059] S plainwin =S win *tan(d win ,d sun ) (3)

[0060] In formula (3), S win is the area of ​​the window; see Figure 5, S plainwin It can be the area of ​​the plane shown by 51 in FIG. 5 .

[0061] Since the light intensity generated by direct light has a certain reflection in the whole room, according to the diffuse reflection coefficient c1=0.3 and the diffuse reflection theory of light, the average illumination I of direct light and diffuse reflected light in the room can be calculated. ave1 :

[0062] In formula (4), S room is the area of ​​the room, is the area ratio of windows to rooms, The value of is generally Between, cos(d win ,d sun ) is the cosine of the angle between the window direction and the sun direction, cos(d win ,d sun ) can be obtained according to the window azimuth; f(S plainwin , S room ) is the ratio of the spot area formed by direct light entering the room through the window to the room area.

[0063] 2. Average illumination of scattered light in the room

[0064] Scattered light provides a value for indoor lighting in a diffuse manner. Therefore, the average illuminance of the room is I ave2 , can be calculated according to formula (5).

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

[0066] After obtaining the average illuminance of direct light and diffuse reflected 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 reflected light in the room, and the average illuminance of scattered light in the room, as shown in formula (6).

[0067] FIG6 is a flow chart of a method for adjusting indoor light intensity according to another embodiment of the present application. As shown in FIG6 , in the embodiment shown in FIG3 of the present application, before step 302, the following steps may also be included:

[0068] In step 601 , the electronic device 100 obtains a second illuminance collected by a illuminance sensor within a predetermined time period.

[0069] The predetermined time period may be a period of time before the current moment and may be set during specific implementation. This embodiment does not limit the predetermined time period.

[0070] In step 602 , the electronic device 100 filters the second illuminance to obtain a third illuminance, and acquires a collection time of the third illuminance.

[0071] In some examples, the electronic device 100 can filter out the maximum illuminance from the above-mentioned second illuminances as the third illuminance, and obtain the collection time of the third illuminance. Of course, this is only one implementation method of this embodiment and does not constitute a limitation of this embodiment. This embodiment does not limit the method of filtering to obtain the third illuminance.

[0072] In step 603, the electronic device 100 determines the window azimuth according to the third illuminance, the time of collecting the third illuminance, the longitude and latitude of the location of the room, and the time zone to which the longitude and latitude belong.

[0073] In this embodiment, the above-mentioned window azimuth is the solar azimuth. In specific implementation, the electronic device 100 can use the ecliptic coordinate system in the celestial coordinate system to calculate the above-mentioned window azimuth based on the third illuminance, the collection time of the third illuminance, the longitude and latitude of the location of the above-mentioned room, and the time zone to which the above-mentioned longitude and latitude belong.
