[0037] In the embodiments of the present disclosure, smart home appliances refer to home appliance products that are formed by introducing microprocessors, sensor technology, and network communication technology into home appliances. They have the characteristics of intelligent control, intelligent perception, and intelligent application. The operation process of smart home appliances often relies on the application and processing of modern technologies such as the Internet of Things, the Internet, and electronic chips. For example, smart home appliances can realize remote control and management of smart home appliances by users by connecting to electronic devices.

[0038] In the disclosed embodiments, a terminal device refers to an electronic device with a wireless connection function. The terminal device can communicate with the above-mentioned smart home appliances by connecting to the Internet, or can communicate with the above-mentioned smart home appliances directly through Bluetooth, WiFi, etc. In some embodiments, the terminal device is, for example, a mobile device, a computer, or a vehicle-mounted device built into a hover car, or any combination thereof. Mobile devices may include, for example, mobile phones, smart home devices, wearable devices, smart mobile devices, virtual reality devices, etc., or any combination thereof, wherein wearable devices include, for example, smart watches, smart bracelets, pedometers, etc.

[0039] The smart home industry has evolved through the stages of single-product intelligence, collaborative intelligence, and decision-making intelligence. The decision-making intelligence stage requires devices to be able to actively perceive, learn, and make decisions, thereby providing proactive services. Perception is the beginning of the entire service process and a crucial step, directly impacting the level of learning and decision-making. Currently, users have a high demand for greater awareness of their home environment, necessitating the addition of intelligent sensing products that can utilize their perception capabilities to obtain various user and environmental information, thereby enabling proactive adjustments to home devices. Related technologies disclose a multi-home appliance control method based on a wearable device. The method comprises the following steps: obtaining three-dimensional spatial information about the user's room and the location of home appliances; placing an ultrasonic ranging device in the room for positioning; obtaining sensor information from the wearable device; a training phase to extract sensor data feature values ​​and establish a feature database and classifier; and a control phase to obtain and execute user commands based on the sensor information returned by the wearable device and auxiliary positioning equipment. By analyzing the inertial measurement unit and ultrasonic ranging information, the wearable device's position and orientation can be calculated. Using pre-established data tables, the method accurately determines the device selected by the user in a multi-home appliance scenario. The use of related technologies, which combine ultrasonic ranging devices with wearable devices and auxiliary positioning devices to locate users, has, to a certain extent, met the perception needs of the intelligent decision-making stage of smart homes. However, in actual application, the use of related technologies requires the additional installation of ultrasonic ranging devices, which is costly. Moreover, these technologies passively execute user control commands, which is inconsistent with the development trend of the intelligent decision-making stage of smart homes.

[0040] The present disclosure discloses a terminal that can be installed on any smart home appliance and communicate with each smart home appliance in the user's home. The terminal also includes a processor that is electrically connected to the above-mentioned electrical components and is used to control the operation of the above-mentioned electrical components.

[0041] Figures 1 to 4 This is a schematic diagram of a method for controlling a home appliance provided by an embodiment of the present disclosure. Any of the following methods can be executed in a terminal or in a server or other device that is communicatively connected to the terminal. In the embodiments of the present disclosure, the terminal is used as the execution subject to illustrate the solution.

[0042] Based on the above terminal structure, such as Figure 1 As shown, an embodiment of the present disclosure provides a method for controlling a home appliance, including:

[0043] S01, the terminal controls the speaker of the first household appliance to emit ultrasonic waves, and receives the reflected sound waves of the ultrasonic waves through the microphone of the first household appliance.

[0044] S02: The terminal analyzes the reflected sound waves to obtain the distance and / or direction of the user.

[0045] S03: The terminal controls the first home appliance and other home appliances other than the first home appliance according to the distance and / or direction of the user.

[0046] The user's distance refers to the distance between the user and the first home appliance, and the user's position refers to the user's position relative to the first home appliance. The first home appliance can be any home appliance with a built-in speaker and microphone, for example, an air conditioner or a television. Other home appliances other than the first home appliance can be other home appliances other than the home appliance on which the terminal is installed, i.e., second home appliances, such as a lighting fixture or a robot vacuum.

[0047] Using the method for controlling home appliances provided by the embodiments of the present disclosure, the speaker of a first home appliance is controlled to emit ultrasonic waves, and the reflected sound waves of the ultrasonic waves are received through the microphone of the first home appliance. The reflected sound waves are analyzed to obtain the distance and / or direction of the user, and the first home appliance and other home appliances outside the first home appliance are controlled based on the distance and / or direction of the user. By emitting ultrasonic waves through the speaker of the home appliance itself and receiving the reflected sound waves through the microphone of the home appliance, the user's perception and positioning are achieved, and the home appliance is actively controlled, which reduces the perception cost of smart home appliances and meets the perception needs of the intelligent stage of smart home decision-making. This enables home appliances to better proactively provide services, in line with the development trend of the intelligent stage of smart home decision-making.

[0048] Based on the above terminal structure, such as Figure 2As shown, an embodiment of the present disclosure provides a method for controlling a home appliance, including:

[0049] S21, the terminal controls the speakers of the air conditioner and / or TV to emit ultrasonic waves.

[0050] S22: The microphone of the terminal controlling the air conditioner and / or the television receives the reflected sound waves of the ultrasonic wave.

[0051] S02: The terminal analyzes the reflected sound waves to obtain the distance and / or direction of the user.

[0052] S03: The terminal controls the first home appliance and other home appliances other than the first home appliance according to the distance and / or direction of the user.

[0053] Using the method for controlling home appliances provided in the embodiments of the present disclosure, since current smart home appliances typically have voice assistance functions, air conditioners and televisions are typically equipped with speakers and microphones. The terminal controls the speakers of the air conditioner and / or television to emit ultrasonic waves and controls the microphones of the air conditioner and / or television to receive reflected sound waves from the ultrasonic waves. This enables the smart home appliance to transmit ultrasonic waves and receive reflected sound waves through its own speakers and microphones, reducing the cost of user perception and positioning.

[0054] Based on the above terminal structure, such as Figure 3 As shown, an embodiment of the present disclosure provides a method for controlling a home appliance, including:

[0055] S01, the terminal controls the speaker of the first household appliance to emit ultrasonic waves, and receives the reflected sound waves of the ultrasonic waves through the microphone of the first household appliance.

[0056] S31, the terminal obtains the first time when the speaker emits ultrasonic waves and the second time when the microphone receives reflected sound waves.

[0057] S32: The terminal calculates the time difference between the first time and the second time.

[0058] S33, the terminal calculates S=V×T / 2.

[0059] In step S33 , S is the distance between the user and the first household appliance, V is the propagation speed of the ultrasonic frequency band in the air, and T is the time difference between the first time and the second time.

[0060] S03: The terminal controls the first home appliance and other home appliances other than the first home appliance according to the distance and / or direction of the user.

[0061] In addition to using the aforementioned beamforming technology to determine the user's position, the terminal can also employ array microphone technology. Microphones are installed at multiple locations on the first home appliance to form a microphone array. When an ultrasonic signal reflects from the user, the microphones at different locations receive the signal at slightly different times or with varying signal strengths. By analyzing these differences, the time or phase differences between the ultrasonic signals reaching the different microphones can be calculated. Using these time or phase differences, combined with the known microphone spacing and ultrasonic velocity, the user's direction relative to the microphone array can be calculated. Furthermore, the Doppler effect can be employed. If the user moves relative to the speaker and microphone of the first home appliance, the frequency of the reflected ultrasonic signal changes. This phenomenon is known as the Doppler effect. By analyzing the degree of the Doppler frequency shift in the reflected sound wave, the user's direction and speed can be determined.

[0062] Using the method for controlling a home appliance provided in an embodiment of the present disclosure, a terminal obtains the first time a speaker emits an ultrasonic wave and the second time a microphone receives the reflected sound wave. The terminal then calculates the time difference between the first and second times. Half of this time difference is the time it takes for the ultrasonic wave to travel one way between the first home appliance and the user. Since the speed of ultrasonic waves in air is a known parameter, the product of the speed of ultrasonic waves in air and the time it takes for the ultrasonic wave to travel one way between the first home appliance and the user is the distance between the first home appliance and the user.

[0063] Based on the above terminal structure, such as Figure 4 As shown, an embodiment of the present disclosure provides a method for controlling a home appliance, including:

[0064] S01, the terminal controls the speaker of the first household appliance to emit ultrasonic waves, and receives the reflected sound waves of the ultrasonic waves through the microphone of the first household appliance.

[0065] S41: The terminal obtains the signal strength and / or time when the reflected sound wave reaches different microphones.

[0066] S42: The terminal determines the direction of the microphone that receives the reflected sound wave with the greatest signal strength and / or the earliest time as the direction of the user.

[0067] S03: The terminal controls the first home appliance and other home appliances other than the first home appliance according to the distance and / or direction of the user.

[0068] Using the method for controlling home appliances provided by the embodiments of the present disclosure, the terminal obtains the signal strength and / or time of the reflected sound waves reaching different microphones, and determines that the direction pointed by the microphone that receives the reflected sound wave with the largest signal strength and / or the earliest time is the user's direction. By controlling the emission direction of the speaker of the first home appliance, an ultrasonic beam pointing in different directions can be generated. Then, a microphone array is used to receive the reflected ultrasonic signal, that is, to receive the reflected sound wave. By analyzing which microphone receives the reflected sound wave with the largest signal strength or the earliest time, the user's direction can be determined.

[0069] Optionally, the terminal controls the first household appliance and other household appliances other than the first household appliance according to the distance and / or direction of the user, including: when the terminal detects that the user is approaching through the reflected sound waves of the TV at night, the terminal controls to turn on the lights; when the terminal detects that the user is away from the TV and cannot be detected through the reflected sound waves of the TV at night, after a first period of time, the terminal controls to turn off the lights and the TV.

[0070] Among them, the terminal can determine whether it is daytime or nighttime in any one or more ways. Specifically, some smart home appliances are usually equipped with light sensors, also called photoresistors or photodiodes. These sensors can detect the brightness level of the surrounding environment, so the terminal can determine whether it is daytime or nighttime through the light sensor of the smart home appliance. When the ambient light drops below the first light threshold, the terminal determines that it is nighttime; when the light intensity rises above the second light threshold, the terminal determines that it is daytime. The terminal can also determine whether it is daytime or nighttime based on the internal clock of the smart home appliance and the preset sunrise and sunset times. The terminal can also make a comprehensive judgment based on the above methods. For example, when the light sensor detects that the light is reduced, the terminal checks whether the current time is close to the preset sunset time, so as to more accurately determine whether it is nighttime.

[0071] Thus, when the reflected sound waves from the TV detect a user approaching at night, it determines that the user may be watching TV. Therefore, the terminal controls the lighting to turn on, illuminating the room for the user, making it easier for the user to turn on the TV or walk, and preventing the user from falling. When the reflected sound waves from the TV detect that the user is no longer detectable at night, it indicates that the user has left the room where the TV is located, and the user is determined to have finished watching TV. Therefore, after a first time period, the terminal controls the lighting and TV to turn off, reducing energy consumption.

[0072] Optionally, the terminal controls the first household appliance and other household appliances other than the first household appliance according to the distance and / or direction of the user, and also includes: when the reflected sound waves of the air conditioner are detected at night that the user returns to the bedroom, the terminal controls the air conditioner to adjust the angle of the air guide plate according to the user's direction.

[0073] In this way, when the reflected sound waves of the air conditioner detect that the user returns to the bedroom at night, the terminal controls the air conditioner to adjust the angle of the air deflector according to the user's orientation, so that the angle of the air deflector of the air conditioner matches the user's current distance and / or orientation, thereby avoiding the person from blowing the wind, or blowing the wind towards the person.

[0074] Optionally, the terminal controls the first household appliance and other household appliances other than the first household appliance according to the distance and / or direction of the user, and also includes: when the terminal detects that the user goes out through the reflected sound waves of the TV during the day, the terminal turns off the TV and controls the sweeper to clean.

[0075] In this way, when the reflected sound waves from the TV are detected during the day when the user is out, it is determined that the user is out. Therefore, the terminal turns off the TV to save energy and controls the sweeper to clean the room when the user is out, thereby reducing interference to the user.
