[0035] In order to enable those skilled in the art to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0036] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0037] The method for controlling smart curtains provided in the embodiment of the present application can be widely used in smart home (SmartHome), smart home, smart home equipment ecology, smart residential (Intelligence House) ecology and other whole-house intelligent digital control application scenarios. Optionally, in this embodiment, the method for controlling smart curtains can be applied to Figure 1 In the hardware environment composed of the terminal device 102 and the server 104 shown in FIG. Figure 1 As shown, the server 104 is connected to the terminal device 102 through a network, and can be used to provide services (such as application services, etc.) for the terminal or the client installed on the terminal. A database can be set on the server or independently of the server to provide data storage services for the server 104. Cloud computing and / or edge computing services can be configured on the server or independently of the server to provide data computing services for the server 104. It should be understood that the above-mentioned terminal device 102 in the embodiment of the present application can be a smart curtain.

[0038] The existing automatic control method for smart curtains directly adjusts the curtain equipment. The parameters of the equipment adjustment are pre-set according to time, geographical location and other conditions. Therefore, most users may have the same adjustment parameters, which lacks personalization and cannot meet the different preferences of different users for curtain adjustment.

[0039] However, if you try to install a light sensor on each curtain, the price of a light intensity sensor that can grade the light intensity ranges from hundreds to thousands, which will greatly increase the production cost of smart curtains. In addition, the sensor has a limited lifespan, which makes subsequent maintenance inconvenient, thus affecting the adjustment accuracy of the curtains.

[0040] Based on this, an embodiment of the present application provides a method for controlling smart curtains, which uses the angle information of sunlight and real-time outdoor lighting information to adjust the curtains. It has low cost and high data accuracy, thereby improving the adjustment accuracy of the smart curtains.

[0041] Combined Figure 2 As shown, a method for controlling an intelligent curtain provided by an embodiment of the present application is as follows Figure 2 As shown, the method includes:

[0042] S201: Obtain the angle information of sunlight at the current moment at the location of the target intelligent curtain.

[0043] S202: Determine the indoor light intensity at the current moment according to the angle information and the outdoor light intensity at the current moment.

[0044] S203: Adjust the target intelligent curtain according to the indoor light intensity and the angle information.

[0045] For the above method provided by the embodiment of the present application, first obtain the angle information of sunlight and the outdoor light intensity at the current moment at the location of the target intelligent curtain, and based on the angle information of sunlight and the outdoor light intensity, determine the indoor light intensity at the current moment, and then adjust the target intelligent curtain. The embodiment of the present application does not require the installation of sensors, and can realize the automatic control of the curtain only through the light information of sunlight. Therefore, it is not affected by the installation position and sensitivity of the sensors, and the control of the curtain is more accurate, and at the same time, the cost of the intelligent curtain is effectively saved.

[0046] Optionally, the angle information of sunlight includes the solar azimuth angle and the solar altitude angle; determining the indoor light intensity at the current moment according to the angle information of sunlight and the outdoor light intensity at the current moment includes: determining the incident angle of sunlight according to the solar azimuth angle, the solar altitude angle and the window azimuth angle; determining the indoor light intensity at the current moment according to the incident angle and the outdoor light intensity at the current moment.

[0047] Figure 3 It is a schematic diagram of the angle information of sunlight. The solar altitude angle refers to the angle between the incident direction of sunlight and the ground plane direction for a certain point on the earth, that is, the solar altitude angle refers to the angle between the solar rays at a certain place and the tangent line of the landmark connected to the earth's center through this place. The solar altitude angle is Figure 3 the Elevation Angle in

[0048] The solar azimuth angle is the deviation angle of the orientation relative to the due north. The sun rises in the east and sets in the west. The azimuth angle ranges from 0 to 360 degrees from 0:00 to 24:00 at night. Convert the azimuth angle to the angle between the window and the sun rays. The solar altitude angle is Figure 3 the zimuthAngle in

[0049] Figure 4It is the angle between the azimuth of sunlight and the window for each time period. The azimuth angle of the window is the angle between the orientation of the window and the set coordinate system. For example, taking the north-up, south-down, west-left, and east-right as the coordinate axes, the window facing due north is 0 degrees, the window facing due south is 180 degrees, the window facing due west is -90 degrees, the window facing due east is +90 degrees, and the azimuth angle of the window in other directions is the angle between the window orientation and the coordinate axes. Of course, the coordinate system can also be formulated according to other rules, and the embodiments of the present application do not limit this. As Figure 4 shown, taking the south-facing window as an example and only considering the daytime situation, the sun angle starts from 0 degrees in the morning and reaches about 180 degrees in the evening. The angle between the sun rays and any window with any orientation at any moment can be obtained through calculation.

[0050] The outdoor light intensity at the current moment can be obtained from meteorological data. The granularity of the light intensity in meteorological data is very fine and can be accurate to the district or county level. By accessing the light intensity, the cost of installing sensors on the curtains can be saved. The meteorological data can be directly obtained from the meteorological server.

[0051] Specifically, the indoor light intensity can be calculated by the following formula:

[0052] IndoorLightIntensity=sin(θ)*outdoorLightIntensity

[0053] Among them, the angle between the window and the sun rays can be calculated in real time as θ. The light intensity entering the room is recorded as the indoor light intensity (IndoorLightIntensity), and outdoorLightIntensity is the outdoor light intensity. In this way, using the information of sunlight and the house location information, the indoor illuminance at the current moment can be obtained without the help of sensors, effectively saving the cost of intelligent curtains.

[0054] Combined with Figure 5 shown, it is another method for controlling an intelligent curtain provided by the embodiments of the present application. As Figure 5 shown, this method includes:

[0055] S501: Obtain the angle information of sunlight at the current moment at the location of the target intelligent curtain.

[0056] S502: Determine the indoor light intensity according to the angle information of sunlight and the outdoor light intensity at the current moment.

[0057] S503: Determine the incident angle of sunlight according to the sun azimuth angle, the sun altitude angle, and the window azimuth angle;

[0058] S504: Determine the indoor light intensity according to the incident angle and the outdoor light intensity at the current moment.

[0059] S505: Determine the lighting level based on the indoor light intensity and the incident angle.

[0060] S506: Determine the curtain control strategy according to the lighting level.

[0061] S507: Adjust the angle of the smart curtain based on the curtain control strategy.

[0062] In this embodiment, after determining the indoor light intensity, the lighting level is jointly determined according to the light intensity and the incident angle. According to different levels, the curtain control strategy is determined from the preset corresponding relationship. In this way, different lighting levels adopt different strategies, and the strategies corresponding to each level can be adjusted at any time according to the longitude and latitude, climate, season, etc. of the city where it is located. The control process is flexible and the adaptation range is wide.

[0063] Optionally, the lighting levels include weak, moderate, strong, and extremely strong. Determining the lighting level according to the light intensity and the incident angle includes: when the incident angle is less than or equal to the preset angle, determining the lighting level as weak; or, when the incident angle is greater than the preset angle and the indoor light intensity is less than or equal to the first preset intensity, determining the lighting level as moderate; or, when the incident angle is greater than the preset angle, the indoor light intensity is greater than the first preset intensity, and the indoor light intensity is less than or equal to the second preset intensity, determining the lighting level as strong; or, when the incident angle is greater than the preset angle and the indoor light intensity is greater than the second preset intensity, determining the lighting level as extremely strong. Among them, the first preset intensity is less than the second preset intensity.

[0064] In this embodiment, the lighting level is divided into four levels. According to the actual situation and customer needs, the lighting level can also be divided into other numbers of levels. For example, two levels, three levels, five levels or more levels. The embodiments of the present application do not make limitations.

[0065] It can also be understood that the lighting level can be fixed or changed at any time. For example, when the sunlight intensity is weak in winter, fewer lighting levels can be set. When the sunlight intensity is strong in midsummer, more lighting levels can be set. Whether the lighting level is fixed or not does not affect the implementation of the embodiments of the present application.

[0066] Combined with Figure 6 As shown, another method for controlling a smart curtain provided by an embodiment of the present application is as Figure 6 shown. The method includes:

[0067] S601: Obtain the angle information of the sunlight at the current moment at the position where the target smart curtain is located.

[0068] S602: Determine the indoor light intensity at the current moment based on the angle information of sunlight and the outdoor light intensity at the current moment.

[0069] S603: Determine the incident angle of sunlight based on the azimuth angle of sunlight, the altitude angle of sunlight, and the azimuth angle of the window.

[0070] S604: Determine the indoor light intensity based on the incident angle and the outdoor light intensity at the current moment.

[0071] S605: Determine the light level based on the light intensity and the incident angle.

[0072] S606: When the light level is weak, determine that the angle of the target intelligent curtain is always fully open.

[0073] S607: Alternatively, when the light level is moderate, determine that the angle of the target intelligent curtain is parallel to the sunlight in real time.

[0074] S608: Alternatively, when the light level is strong, determine that the angle between the target intelligent curtain and the sunlight is a preset angle in real time.

[0075] S609: Alternatively, when the light level is extremely strong, determine that the angle of the target intelligent curtain is always perpendicular to the sunlight.

[0076] S610: Adjust the angle of the intelligent curtain based on the curtain control strategy.

[0077] In the above embodiments, when the light level is moderate, controlling the rotation direction of the blades of the target intelligent curtain to be parallel to the sunlight can block a part of the light, but not too much to cause insufficient indoor light. When the light level is strong, keeping the rotation direction of the blades of the target intelligent curtain at a preset angle with the sunlight, and this preset angle can be preset and saved according to user habits, or can be updated at any time. When the light level is extremely strong, controlling the rotation direction of the blades of the target intelligent curtain to be always perpendicular to the sun rays can ensure the indoor brightness while avoiding direct sunlight. In this way, setting the target intelligent curtain to follow the sun can ensure that the sunlight in the house is always in a balanced state, neither too dark nor too bright, improving the user experience.

[0078] Specifically, refer to Figure 7 As shown, it is a schematic diagram of a curtain following sunlight provided by an embodiment of the present application. Among them, the straight line with an arrow represents the light ray of sunlight, and the straight line without an arrow represents the rotatable blade on the curtain.

[0079] Combined with Figure 8 As shown, it is another method for controlling an intelligent curtain provided by an embodiment of the present application, as Figure 8As shown, the method includes:

[0080] S801: Obtain the angle information of sunlight at the current moment at the location where the target intelligent curtain is located.

[0081] S802: Determine the indoor light intensity at the current moment according to the angle information of sunlight and the outdoor light intensity at the current moment.

[0082] S803: Adjust the intelligent curtain according to the indoor light intensity and the angle information.

[0083] S804: Obtain the preset user habit model.

[0084] S805: Input the angle information into the user habit model to obtain the target position output by the user habit model.

[0085] S806: Adjust the opening and closing degree of the target intelligent curtain so that the sunlight irradiation range does not include the target position.

[0086] In the embodiment of the present application, a model is further trained according to user habits, and the position or range that the user does not want sunlight to irradiate is automatically recognized based on the user habit model, and then the opening and closing of the target intelligent curtain is controlled, further improving the intelligence level of the curtain and the human-computer interaction friendliness.

[0087] Optionally, the user habit model is trained by the following method: obtain multiple groups of training data; wherein, each group of training data includes the angle information when the user adjusts the curtain, and the label information indicating the target position where the user wants to avoid sunlight; train the user habit model based on the multiple groups of training data.

[0088] Specifically, within a certain period of time, collect the altitude angle and azimuth angle of the sun each time the user manually controls the curtain. According to the altitude angle, the depth of sunlight entering the room can be calculated, and according to the azimuth angle, the position where the light shines can be calculated. Therefore, according to the altitude angle and azimuth angle, the position where the user wants to avoid direct sunlight can be calculated each time the curtain is adjusted. For example, if the user has cosmetics on the bedside table and does not want to be directly irradiated by sunlight, when the sun reaches this position next time, the sunlight can be directly and vertically blocked to avoid direct sunlight hitting this position.

[0089] Combined with Figure 9 As shown, it is a method for controlling an intelligent curtain in an actual application scenario provided by the embodiment of the present application. As Figure 9 shown, the method includes:

[0090] 1. Determine the longitude and latitude of the user's current location according to the user's city, and calculate the azimuth angle and altitude angle of sunlight based on the longitude, latitude, and the current time.

[0091] 2. The window angle can be determined according to the window orientation, and the incident angle of sunlight can be calculated based on the window angle, the azimuth angle, and the altitude angle of sunlight.

[0092] 3. Based on the incident angle and the light intensity, the indoor light intensity Rinner at the current moment can be determined.

[0093] 4. By inputting the incident angle and the indoor light intensity into the perception model, the current light level can be obtained.

[0094] Among them, in the perception model, the preset angle is set to 10, the first preset intensity is set to 1000, and the second preset intensity is set to 3500.

[0095] 5. Execute the decision model.

[0096] When the light level is weak, the curtain is fully opened.

[0097] When the light level is moderate, keep the blades of the curtain always parallel to the sunlight.

[0098] When the light level is strong, keep the blades of the curtain at a certain angle to the sunlight.

[0099] When the light level is extremely strong, keep the blades of the curtain perpendicular to the sunlight.

[0100] 6. In the decision model, there is also a user habit model. Based on the output of the user habit model, the opening and closing angle of the curtain is controlled to ensure that the sunlight does not shine on the target position.

[0101] In the embodiment of the present application, the light intensity in the real-time weather data is used to replace the sensor installed on the curtain, saving the curtain cost and eliminating the problem of later sensor maintenance. Moreover, the curtain can be adjusted in real time according to the light intensity to keep a suitable light intensity indoors. Further, the user's usage habits are recorded to customize a personalized curtain automatic control strategy for the user.

Therefore, it is not affected by the installation position and sensitivity of the sensors, the control of the curtain is more accurate, and at the same time, the cost of the intelligent curtain is effectively saved.
