Smart home control method, control device and machine readable storage medium

Abstract

The invention belongs to the technical field of Internet of Things, and particularly provides a smart home control method and device and a machine readable storage medium. The control method comprises the steps that the outdoor wind speed and wind direction are obtained; in response to the wind speed reaching the preset level, judging whether a windward window which faces the same direction as the wind direction and is opened exists or not; and if the opened windward window exists, the windward window is closed. It can be seen that when the outdoor wind speed reaches the preset level, whether the windward window which faces the same direction as the wind direction and is opened exists or not is judged, and therefore whether the outdoor weather condition affects the indoor space or not is judged. And when the windward window is opened, the windward window is closed, so that dust is prevented from being blown into a room by outdoor wind.

[0001] The present invention belongs to the technical field of Internet of Things, and specifically provides a control method, a control device and a machine-readable storage medium for a smart home. Background Art

[0002] With the advancement of technology and the improvement of people's living standards, smart home appliances such as smart windows, smart speakers, and smart kitchenware have entered more and more households.

[0003] Existing smart windows can automatically open and close according to user instructions. However, existing smart windows cannot automatically identify outdoor weather conditions, cannot determine the impact of outdoor weather conditions on indoor conditions, and cannot automatically open and close according to indoor and outdoor conditions. Therefore, the intelligence of existing smart windows is relatively poor. Summary of the invention

[0004] One purpose of the present invention is to solve the problem that existing smart windows cannot be opened and closed according to the impact of outdoor weather conditions on indoor conditions.

[0005] A further object of the present invention is to determine whether a through draft can be formed indoors.

[0006] To achieve the above object, the present invention provides a smart home control method, comprising:

[0007] Get outdoor wind speed and direction;

[0008] In response to the wind speed reaching a preset level, determining whether there is a windward window facing the same direction as the wind direction and open;

[0009] If there is an open windward window, close the windward window.

[0010] Optionally, if there is an open windward window, the step of closing the windward window comprises:

[0011] If there is an open windward window, determining whether there is an open leeward window facing away from the wind direction;

[0012] If there is an open leeward window, close the windward window.

[0013] Optionally, if there is an open leeward window, the step of closing the windward window comprises:

[0014] If there is an open leeward window, determining whether there is a door or window between the leeward window and the windward window;

[0015] If the door or window does not exist, close the windward window;

[0016] If the door or window exists, determining whether the door or window is opened;

[0017] If the doors and windows are open, close the windward windows.

[0018] Optionally, if there is an open leeward window, the step of closing the windward window comprises:

[0019] If there is an opened leeward window, obtaining vibration data of the leeward window;

[0020] If the vibration data meets the preset conditions, close the windward window.

[0021] Optionally, if there is an open leeward window, the step of closing the windward window comprises:

[0022] If there is an open leeward window, acquiring sound information through a microphone array;

[0023] identifying all sounds of different frequencies from the sound information;

[0024] Determine the location of the source of all sounds;

[0025] Determining whether all the sound sources include a sound source located outside the leeward window and a sound source located outside the windward window;

[0026] If available, close the windward windows.

[0027] Optionally, the control method further includes:

[0028] If there is an open windward window, determining whether there is a sidewind window facing a direction different from the wind direction;

[0029] If present, open the crosswind windows.

[0030] Optionally, the control method further includes:

[0031] In response to closing the windward window, detecting a current indoor temperature;

[0032] If the current temperature is higher than the suitable temperature range for the human body, turn on the air conditioner.

[0033] Optionally, the step of obtaining outdoor wind speed and wind direction includes:

[0034] In response to the gas stove being turned on, obtaining outdoor wind speed and direction; the windward window is a window of the kitchen where the gas stove is located; or,

[0035] In response to the outdoor air pollution index reaching a preset value, the outdoor wind speed and wind direction are obtained.

[0036] In a second aspect, the present invention further provides a smart home control device, comprising a processor and a memory, wherein a machine executable program is stored in the memory, and when the processor executes the machine executable program, the control method described in any one of the first aspects can be implemented.

[0037] The present invention further provides a machine-readable storage medium in a third aspect, on which a machine-executable program is stored. When the machine-executable program is executed by a processor, the control method according to any one of the first aspects is implemented.

[0038] Based on the above description, those skilled in the art can understand that, in the above technical solution of the present invention, when the outdoor wind speed reaches a preset level, it is determined whether there is an open windward window facing the same direction as the wind, thereby determining whether the outdoor weather conditions have an impact on the indoor environment. When there is an open windward window, the windward window is closed to prevent the outdoor wind from blowing dust into the indoor environment.

[0039] Furthermore, when there is an open windward window, it is determined whether there is an open leeward window facing away from the wind direction. If there is an open leeward window, it means that a draft is likely to form indoors, so that outdoor air enters the room from the windward window and blows out of the room from the leeward window. At this time, by closing the windward window, it is possible to prevent the outdoor wind from blowing directly into the room, and to prevent outdoor dust from polluting the indoor environment.

[0040] Furthermore, when there is an open leeward window, sound information is obtained through the microphone array; then all sounds of different frequencies are identified from the sound information; and the locations of the sound sources of all sounds are determined. Then, it is determined whether there are sound sources located outside the leeward window and sound sources located outside the windward window among all the sound sources, so as to determine that the sound transmitted from the windward window and the sound transmitted from the leeward window are received when there are such sound sources, indicating that there is no closed door or window between the windward window and the leeward window. When there is no closed door or window between the windward window and the leeward window, the windward window is connected to the leeward window, and air can flow from the windward window to the leeward window, thereby forming a through wind in the room.

[0041] Other beneficial effects of the present invention will be described in detail below in conjunction with the accompanying drawings so that those skilled in the art can more clearly understand the improved purposes, features and advantages of the present invention.

[0055] It should be understood by those skilled in the art that the embodiments described below are only some embodiments of the present invention, rather than all embodiments of the present invention, and these embodiments are intended to explain the technical principles of the present invention, rather than to limit the protection scope of the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should still fall within the protection scope of the present invention.

[0056] It should be noted that in the description of the present invention, the terms "center", "upper", "lower", "top", "bottom", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0057] Furthermore, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0058] In addition, it should be noted that in the description of the present invention, the terms "cold" and "heat" are two descriptions of the same physical state. That is, the higher the "cold" of a certain target object (such as an evaporator, air, condenser, etc.), the lower the "heat" it has, and the lower the "cold" it has, the higher the "heat" it has. A certain target object will release "heat" while absorbing "cold", and will absorb "heat" while releasing "cold". A certain target object stores "cold" or "heat" to keep the current temperature of the target object. "Refrigeration" and "heat absorption" are two descriptions of the same physical phenomenon, that is, a certain target object (such as an evaporator) will absorb heat while cooling.

[0059] Finally, it should be noted that in the description of the present invention, each functional module can be a physical module composed of multiple structures, components or electronic components, or a virtual module composed of multiple programs; each functional module can be a module that exists independently of each other, or a module divided according to the function of an integral module. Those skilled in the art should understand that, under the premise of being able to implement the technical solution described in the present invention, no matter how the composition, implementation and positional relationship of each functional module change, they will not deviate from the technical principle of the present invention, and therefore should fall within the protection scope of the present invention.

[0060] like Figure 1 As shown, a scene schematic diagram provided by the present invention shows a kitchen 101, a living room 102, a windward window 211, a leeward window 212, a side wind window 213, a door and window 220, a gas stove 300, an air conditioner 400 and a control device 500. Among them, the windward window 211 and the side wind window 213 are arranged on the wall of the kitchen 101, and the leeward window 212 is arranged on the wall of the living room 102. The door and window 220 is arranged between the kitchen 101 and the living room 102. The door and window 220 can be a door, or the skilled person can also set the door and window 220 as a window as needed. The gas stove 300 is arranged in the kitchen 101, and the air conditioner 400 and the control device 500 are both arranged in the living room 102.

[0061] In the present invention, the windward window 211 refers to a window with the same wind direction as the outdoor wind, the leeward window 212 refers to a window opposite to the outdoor wind direction, and the side wind window 213 refers to a window with a different wind direction (eg, vertical) from the outdoor wind direction.

[0062] In other words, in the present invention, the naming of each window is related to the wind direction. Specifically, the window toward which the outdoor wind blows is recorded as the windward window 211, the window away from the outdoor wind is recorded as the leeward window 212, and the window at an angle to the outdoor wind is recorded as the side wind window 213.

[0063] It should be noted that the present invention Figure 1 The scenario shown in the figure is intended to assist in explaining the control method described below, and does not limit the present invention to be applicable to only this scenario. Those skilled in the art may make appropriate adjustments to the applicable scenario of any embodiment described below according to actual needs.

[0064] For example, the present invention is also applicable to scenarios without a gas stove 300 and / or an air conditioner 400, scenarios without side leeward windows 212 and / or wind windows 213 and / or door windows 220, scenarios in which the kitchen 101 and / or the living room 102 are set as a dining room or bedroom, and so on.

[0065] like Figure 2As shown, the smart home control device 500 provided by the present invention includes a processor 510 and a memory 520, and a machine executable program 521 is stored in the memory 520. When the processor 510 executes the machine executable program 521, the control method described in any of the following embodiments can be implemented.

[0066] In the present invention, the memory 520 may include a memory and a non-volatile memory, and provide execution instructions and data to the processor 510. Exemplarily, the memory may be a high-speed random access memory (RAM), and the non-volatile memory may be at least one disk storage.

[0067] In the present invention, the processor 510 is an integrated circuit chip having the ability to process signals. The processor 510 may be a general-purpose processor, such as a central processing unit (CPU), a network processor (NP), a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, microprocessors, and any other conventional processors.

[0068] Continue reading Figure 2 In the present invention, the control device 500 of the smart home may further include a microphone array 530, through which the control device 500 can collect sound information. The control device 500 is configured to analyze the collected sound information to identify all sounds of different frequencies from the sound information. Then, for each frequency of sound, the corresponding sound source position is determined.

[0069] Furthermore, the sound source position may be identified only for the sound information of the frequency whose decibel value reaches a certain value (eg, 30 decibels) to filter out the interference of tiny sounds.

[0070] In addition, those skilled in the art may also integrate the control device 500 into the air conditioner 400 as needed. Those skilled in the art may also use a cloud server or a backend server to replace the control device 500 when there is no need to collect sound information as needed.

[0071] Refer to the following Figures 3 to 8The control method of the smart home in some embodiments of the present invention is described in detail.

[0072] like Figure 3 As shown, in some embodiments of the present invention, the control method of the smart home includes steps S110 to S130, which are as follows:

[0073] Step S110, obtaining outdoor wind speed and wind direction.

[0074] Specifically, the local weather forecast can be obtained through the Internet, thereby obtaining the current outdoor wind speed and direction.

[0075] In addition, the current outdoor wind speed and direction can also be obtained through wind speed sensors and wind direction sensors.

[0076] The trigger instruction for obtaining the outdoor wind speed and direction may be detecting that the gas stove 300 is turned on, or the outdoor air pollution index reaches a preset value. Specifically, step S110 may be as follows: Figure 4 As shown, it includes step S111 or step S112.

[0077] In step S111, in response to the gas stove 300 being turned on, outdoor wind speed and wind direction are obtained.

[0078] In this embodiment, whether the gas stove 300 is turned on may be detected by an infrared sensor or a temperature sensor, or by a switch sensor on the gas stove 300 .

[0079] In step S112, in response to the outdoor air pollution index reaching a preset value, the outdoor wind speed and wind direction are obtained.

[0080] The preset value may be 150, or any other feasible value, such as 100, 120, 130, etc.

[0081] In this embodiment, the local weather forecast can be obtained through the Internet, thereby obtaining the current outdoor air pollution index.

[0082] Step S120, in response to the wind speed reaching a preset level, it is determined whether there is a windward window 211 that faces the same direction as the wind and is open.

[0083] Among them, the preset levels are level three, level four, level five or level six.

[0084] Exemplarily, when step S110 specifically performs step S111, the preset level is five; when step S110 specifically performs step S112, the preset level is three.

[0085] In the present invention, each window is a smart window, which can be opened and closed automatically. And each window can detect whether it is currently in an open state or a closed state. Since smart windows with this function can be purchased on the market and belong to common knowledge in the field, they will not be described here.

[0086] Furthermore, in the present invention, the orientation of each window is pre-stored in the control device 500 .

[0087] Step S130: If there is an open windward window 211, close the windward window 211.

[0088] Those skilled in the art will appreciate that if there is a windward window 211 facing the outdoor wind, the outdoor wind will carry dust into the room. Closing the windward window 211 can effectively avoid this situation.

[0089] like Figure 5 As shown, step S130 further includes:

[0090] Step S131, if there is an open windward window 211, determine whether there is an open leeward window 212 that faces away from the wind direction.

[0091] Those skilled in the art will appreciate that if there is an open leeward window 212, it means that a draft is likely to form indoors, causing outdoor air to enter the room from the windward window 211 and be blown out of the room from the leeward window 212. In this case, outdoor dust will enter the room along with the wind, polluting the indoor environment.

[0092] Step S132, if there is an open leeward window 212, close the windward window 211.

[0093] Those skilled in the art will appreciate that after closing the windward window 211, the leeward window 212 can continue to allow indoor air to exchange with outdoor air by diffusion, thereby avoiding a stuffy situation indoors. At the same time, since the leeward window 212 is located in a leeward position, it is difficult for outdoor dust to enter the room through it, thereby ensuring the cleanliness of the room.

[0094] Furthermore, since the windward window 211 and the leeward window 212 are often located in two different rooms and a door is often provided between the two rooms, if the door is closed, no draft will be formed indoors, and under the effect of air pressure, less wind and dust can enter the room through the windward window 211, which can be ignored.

[0095] To this end, step S132 may further include Figures 6 to 8 The steps shown in any of the accompanying drawings.

[0096] like Figure 6 As shown, in the first example of this embodiment, step S132 may further include:

[0097] Step S13211, if there is an open leeward window 212, determine whether there is a door or window 220 between the leeward window 212 and the windward window 211.

[0098] In this step, the door and window 220 can automatically detect whether it is in an open state or a closed state. And the position of the door and window 220 in the room is also pre-stored in the control device 500.

[0099] Step S13212: if there is no door or window 220, it means that a draft will be formed in the room and the room may be polluted, and the windward window 211 is closed.

[0100] Step S13213, if the door or window 220 exists, determine whether the door or window 220 is opened.

[0101] Step S13214, if the door and window 220 are opened, it means that a draft will be formed in the room and the room may be polluted, so the windward window 211 is closed.

[0102] Further, if the door and window 220 are closed, the windward window 211 may not be closed.

[0103] like Figure 7 As shown, in the second example of this embodiment, step S132 may further include:

[0104] Step S13221: If there is an open leeward window 212, obtain vibration data of the leeward window 212.

[0105] In the present invention, a vibration sensor is arranged on each window, and the vibration sensor is used to detect the vibration generated by the window when wind blows through the window.

[0106] Step S13222, if the vibration data meets the preset conditions, it means that there is no door or window 220 between the leeward window 212 and the windward window 211, or the door or window 220 is opened and there is a through draft in the room, and the windward window 211 is closed at this time.

[0107] The vibration data and the preset condition may be amplitude or vibration frequency. The specific value of the preset condition may be determined by performing multiple tests on the leeward window 212 when there is a draft in the room and calculating the average value of the multiple test results.

[0108] Those skilled in the art will appreciate that, compared to the first example, the second example of the present invention no longer requires that the doors and windows 220 between the windward window 211 and the leeward window 212 must be able to detect their own status, and eliminates the need for users to upload the positions of the doors and windows 220 between the windward window 211 and the leeward window 212.

[0109] like Figure 8 As shown, in the third example of this embodiment, step S132 may further include:

[0110] Step S13231, if there is an open leeward window 212, sound information is obtained through the microphone array 530.

[0111] Step S13232, identify all sounds of different frequencies from the sound information.

[0112] Step S13233, determine the locations of the sound sources of all sounds.

[0113] Step S13234, determining whether among all the sound sources there are sound sources located outside the leeward window 212 and sound sources located outside the windward window 211.

[0114] Furthermore, the location of the sound source can be identified for the sound information of the frequency whose decibel value reaches a certain value (for example, 30 decibels) to filter out the interference of tiny sounds.

[0115] Step S13235, if yes, it means that the sound transmitted from the windward window 211 and the sound transmitted from the leeward window 212 are received, that is, there is no closed door or window 220 between the windward window 211 and the leeward window 212 (the sound is not blocked by the closed door or window 220), and the windward window 211 is closed at this time.

[0116] This example has the same technical effect as the second example, and will not be described in detail here.

[0117] It should be noted that the above-mentioned embodiment of the present invention is only a basic embodiment of the present invention. In other embodiments of the present invention, those skilled in the art may also adjust, optimize and configure the schemes and steps in the above-mentioned embodiments as needed to achieve further technical effects. Other embodiments of the present invention different from the above-mentioned embodiments will be described in conjunction with the accompanying drawings hereinafter. Of course, those skilled in the art may also make appropriate modifications to the execution order, operating conditions and quantity of the steps in the embodiments to be described hereinafter according to actual needs. The modified embodiments do not deviate from the technical concept and / or technical principle of the present invention and should still fall within the scope of protection of the present invention.

[0118] like Fig. 9As shown, in some further embodiments of the present invention, compared with some embodiments described above, the smart home control method further includes, after step S120:

[0119] Step S210, if there is an open windward window 211, determine whether there is a side wind window 213 facing in a direction different from the wind direction.

[0120] The side wind window 213 and the windward window 211 belong to the same room. Figure 1 The kitchen shown in 101.

[0121] Step S220, if present, open the side wind window 213 to allow ventilation of the room where the windward window 211 is located through the side wind window 213 and prevent dust from entering.

[0122] Those skilled in the art can understand that when step S110 specifically performs step S111, some other embodiments of the present invention can prevent the gas stove 300 from being blown out by wind while allowing the heat in the kitchen 101 to dissipate outdoors as quickly as possible.

[0123] like Fig.10 As shown, in some other embodiments of the present invention, compared with some embodiments described above, the smart home control method further includes, after step S130:

[0124] Step S310, in response to closing the windward window 211, detecting the current indoor temperature.

[0125] Further, in response to closing the windward window 211, it is detected whether there is someone in the room. If there is someone, the current temperature in the room is detected; if there is no one, no operation is performed.

[0126] Among them, to detect whether there is someone in the room, an infrared sensor or radar on any indoor device (such as air conditioner 400 or a sweeping machine) can be used to detect whether there is someone in the room; the microphone array 530 described above can also be used to detect whether human voice is collected, so as to determine that there is someone in the room when human voice is collected.

[0127] Step S320: If the current temperature is higher than the suitable temperature range for the human body, turn on the air conditioner 400.

[0128] The suitable temperature range may be any feasible temperature range such as 21°C to 26°C, 23°C to 25°C, 18°C ​​to 26°C, 20°C to 23°C, etc. Moreover, the suitable temperature range may be set by the manufacturer and pre-stored in the air conditioner 400, or may be set by the user.

[0129] For example, the suitable temperature range is 23° C. to 25° C. If the current temperature is 26° C., which is higher than the maximum value of 25° C. in the suitable temperature range, the air conditioner 400 is turned on to cool the room.

[0130] In the present invention, the air conditioner 400 may be located in the room where the windward window 211 is located, or may be located in a room adjacent to the room where the windward window 211 is located.

[0131] Finally, if Fig.11 As shown, the present invention further provides a machine-readable storage medium 600 on which a machine executable program 521 is stored. When the machine executable program 521 is executed by the processor 510, the control method described in any of the above embodiments is implemented.

[0132] The readable storage medium includes: a USB flash drive, a mobile hard disk, a ROM, a RAM, a magnetic disk or an optical disk, and other media that can store program codes.

[0133] So far, the technical solution of the present invention has been described in combination with the above multiple embodiments, but it is easy for those skilled in the art to understand that the protection scope of the present invention is not limited to these specific embodiments. Without departing from the technical principles of the present invention, those skilled in the art can split and combine the technical solutions in the above embodiments, and can also make equivalent changes or replacements to the relevant technical features. Any changes, equivalent replacements, improvements, etc. made within the technical concept and / or technical principles of the present invention will fall within the protection scope of the present invention.
