In related technologies, radars (such as millimeter-wave radars, etc.) are set on home appliances to sense the environment and control the home appliances based on the sensed conditions. In current home environments, when radars are used for detection, the movement of sweepers, pets, etc. is often detected, triggering miscontrol of home appliances.

In addition, the embodiments provided below are partial embodiments for implementing the present disclosure, rather than providing all embodiments for implementing the present disclosure. In the absence of conflict, the technical solutions recorded in the embodiments of the present disclosure can be implemented in any combination.

[0038] It should be noted that, in the embodiments of the present disclosure, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a method or apparatus including a series of elements includes not only the elements explicitly recorded, but also includes other elements not explicitly listed, or also includes elements inherent to the implementation of the method or apparatus.

[0039] For example, the household appliance control method provided in the embodiment of the present disclosure includes a series of steps, but the household appliance control method provided in the embodiment of the present disclosure is not limited to the recorded steps. Similarly, the household appliance control device provided in the embodiment of the present disclosure includes a series of units, but the device provided in the embodiment of the present disclosure is not limited to including the units explicitly recorded, and may also include units required to obtain relevant information or perform processing based on the information.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present disclosure belongs. The terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure.

[0041] It is understandable that in the specific implementation of this application, relevant data is involved. When the embodiments in this application are applied to specific products or technologies, user permission or consent is required, and the collection, use and processing of relevant data need to comply with relevant laws, regulations and standards of relevant countries and regions.

[0042] Figure 1 The flowchart of a method for controlling a household appliance according to an embodiment of the present application is schematically shown. The execution subject of the method for controlling a household appliance may be a household appliance itself with processing capabilities or a control terminal of the household appliance. Household appliances include televisions, refrigerators, washing machines, etc.; the control terminal of a household appliance is a terminal that can control the household appliance, such as a remote control or other dedicated control device, etc. Specifically, in a specific embodiment of the present application, the execution subject of the method for controlling a household appliance is a television, and the controlled household appliance is the television itself.

[0043] Further, such as Figure 1 As shown, the household appliance control method may include steps S110 to S130.

[0044] Step S110, setting a trigger condition for a radar corresponding to the household appliance to obtain a custom trigger condition for the radar, wherein the custom trigger condition includes at least one custom trigger range and a corresponding interaction instruction, and each custom trigger range is less than or equal to a radar limit detection range of the radar;

[0045] Step S120, receiving a trigger signal corresponding to a target trigger range sent by the radar, wherein the trigger signal is sent by the radar when a detection signal that meets a predetermined state appears within the target trigger range, and the target trigger range is one or more of the at least one custom trigger range;

[0046] Step S130, determining an interaction instruction that matches the target trigger range corresponding to the trigger signal, and controlling the home appliance based on the interaction instruction.

[0047] By the user performing setting operations on the control terminal of the home appliance, or by the user performing setting operations on the home appliance, or by the home appliance or the control terminal performing automatic judgment and setting operations, the trigger conditions of the radar corresponding to the home appliance can be set to obtain the customized trigger conditions of the set radar.

[0048] The custom trigger condition includes at least one custom trigger range (eg, 1 or 5, etc.) and a corresponding interaction instruction, wherein each custom trigger range may correspond to an interaction instruction, or a combination of multiple custom trigger ranges may correspond to an interaction instruction.

[0049] After setting the custom trigger condition, when the radar detects a detection signal that meets the predetermined state within the target trigger range, it can send a trigger signal to the execution entity (i.e., the home appliance itself or the control terminal of the home appliance). The trigger signal can be used to inform the execution entity that a detection signal that meets the predetermined state appears within the target trigger range. The target trigger range can be one of the at least one custom trigger range mentioned above or multiple custom trigger ranges.

[0050] For example, when a detection signal that meets the predetermined state appears in custom trigger range 1, trigger signal 1 is issued, and trigger signal 1 can inform that a detection signal that meets the predetermined state appears in custom trigger range 1. When a detection signal that meets the predetermined state appears in custom trigger range 2 and custom trigger range 3, trigger signal 2 is issued, and trigger signal 2 can inform that a detection signal that meets the predetermined state appears in both custom trigger range 2 and custom trigger range 3.

[0051] Among them, each custom trigger range is less than or equal to the radar limit detection range of the radar, and the radar limit detection range is the maximum detection range of the radar under the currently set sensitivity. If a detection signal appears in a range greater than the custom trigger range and less than the radar limit detection range, the radar will not send a trigger signal.

[0052] After the execution subject receives the trigger signal corresponding to the custom trigger range sent by the radar, it can further determine that the trigger signal indicates that a detection signal that meets the predetermined state appears within the target trigger range, and further determine the interaction instruction corresponding to the target trigger range (that is, a certain custom trigger range or a combination of multiple custom trigger ranges) according to the custom trigger condition.

[0053] The interactive instruction is an instruction for interactively controlling the home appliance, for example, the interactive instruction may be an instruction for turning on, turning off, switching channels, adjusting volume, etc. The execution subject may control the home appliance based on the interactive instruction.

[0054] In this manner in the embodiments of the present application, by setting trigger conditions for the radar corresponding to the home appliance, a custom trigger condition for the radar is set, and the custom trigger condition includes at least one custom trigger range and a corresponding interactive instruction. The radar can detect according to the custom trigger range and send a trigger signal, and the trigger signal further triggers the interactive instruction to control the home appliance. This can avoid false detection of areas outside the custom trigger range that lead to false control, thereby achieving interactive control of home appliances based on radar that reliably meets personalized needs, and effectively improving the reliability of interactive control of home appliances based on radar as a whole, thereby improving user experience.

[0055] Described below Figure 1When controlling the household electrical appliances under the embodiment, further optional specific embodiments are provided for each step performed.

[0056] In one embodiment, the trigger conditions for the radar corresponding to the household appliance are set to obtain the custom trigger conditions of the radar, which may include: detecting the marker body by the radar to record at least one wandering boundary of the marker body, each wandering boundary serving as a custom trigger range; setting interaction instructions corresponding to each custom trigger range or a combination of multiple custom trigger ranges.

[0057] In the process of setting the trigger conditions, the marker (such as a human body) can move according to the required boundaries. By detecting the marker through radar, at least one movement boundary (that is, the motion trajectory) of the marker can be recorded. The marker can move to form one or more movement boundaries.

[0058] Each wandering boundary is used as a custom trigger range, and the range data (i.e., boundary data) of each custom trigger range can be stored in a processor storage unit such as SOC in the form of a table. Figure 2 As shown, a custom trigger range 220 is detected and recorded before the location of the radar 210. The custom trigger range 220 can be recorded in a table as "within the range of θ∈(-90°, 90°), r≤f(r,θ)", where θ is the angle between the line connecting each point on the boundary of the custom trigger range and the radar and the forward direction of the radar, and r is the distance from the radar to each point on the boundary of the custom trigger range.

[0059] Furthermore, the user can set the interaction instruction corresponding to each custom trigger range through the instruction association setting operation. For example, if custom trigger range 1, custom trigger range 2 and custom trigger range 3 are set, interaction instruction 1 can be set for custom trigger range 1, interaction instruction 2 can be set for custom trigger range 2, and interaction instruction 3 can be set for custom trigger range 3; at this time, after trigger signal 1 is sent out when a detection signal that meets the predetermined state appears in custom trigger range 1, it can be determined that the target trigger range corresponding to trigger signal 1 is custom trigger range 1, and its matching interaction instruction is interaction instruction 1.

[0060] Furthermore, the user can set the interaction instructions corresponding to the combination of multiple custom trigger ranges through the instruction association setting operation. For example, custom trigger range 1, custom trigger range 2 and custom trigger range 3 are set, and interaction instruction 4 can be set for combination 1 of custom trigger range 1 and custom trigger range 2. At this time, after trigger signal 4 is issued when detection signals that meet the predetermined state appear in both custom trigger ranges 1 and 2, it can be determined that the target trigger range corresponding to trigger signal 4 is the combination of custom trigger ranges 1 and 2, and the interaction instruction matched therewith is interaction instruction 4.

[0061] Furthermore, in one embodiment, the triggering conditions for the radar corresponding to the household appliance are set to obtain the custom triggering conditions for the radar, which may include: obtaining at least one boundary data customized by the user, each of the boundary data serving as a custom trigger range; and setting interaction instructions corresponding to each custom trigger range or a combination of multiple custom trigger ranges.

[0062] The user can directly customize one or more boundary data (such as table data or boundary functions, etc.) through tools such as tables or formula editors according to needs, and then obtain at least one boundary data customized by the user, and each boundary data can be stored in the processor storage unit as a customized trigger range. At the same time, the interaction instruction corresponding to each customized trigger range is set, or the interaction instruction corresponding to the combination of multiple customized trigger ranges is set.

[0063] Furthermore, in one embodiment, setting the trigger conditions for the radar corresponding to the household appliance to obtain the custom trigger conditions of the radar may include: obtaining historical interactive control data of the household appliance; analyzing and setting the custom trigger conditions of the radar based on the historical interactive control data.

[0064] The historical interactive control data is the data recorded when the user controls the home appliance in the past. The historical interactive control data generated within a predetermined time period can be obtained from the record file. The historical interactive control data may include the user's location in the space and the interactive instructions issued to the home appliance at that location.

[0065] By using models such as fine-tuned large language models to analyze the historical interactive control data, the customized trigger conditions of the radar can be intelligently set according to the user's interactive control habits, further improving the control experience of home appliances. Similarly, the customized trigger conditions of the radar include at least one customized trigger range and the corresponding interactive instructions (that is, the interactive instructions corresponding to each customized trigger range or a combination of multiple customized trigger ranges can be set), and each customized trigger range is less than or equal to the radar limit detection range of the radar.

[0066] In one embodiment, the radar includes an antenna array, which includes multiple antennas, adjacent antennas are connected by phase delay lines, and the multiple antennas are arranged vertically in a vertical plane perpendicular to the ground; before receiving a trigger signal corresponding to a target trigger range sent by the radar, the method also includes: controlling the beam of the antenna array to concentrate on a target area in space for detection, wherein the target area refers to an area in the space that is a certain distance above the ground, and the radar sends a corresponding trigger signal when detecting a detection signal that meets a predetermined state within a target trigger range within the target area.

[0067] See also Figure 3 , the multiple antennas (such as Figure 3 The adjacent antennas in the antenna ANT1, antenna ANT2, etc. shown in the figure are connected by a phase delay line 320, and the multiple antennas are arranged vertically in a vertical plane perpendicular to the ground. Figure 4 As shown, the antennas in the antenna array 310 can be beam-shaped in the vertical plane. By setting the installation position of the radar or adjusting the antenna, the beam of the antenna array can be conveniently and flexibly concentrated on the target area in the space for detection, while reducing or avoiding detection of areas outside the target area.

[0068] The target area refers to the area in space that is a certain distance above the ground, e.g. Figure 4 As shown, the target area is a target area 410 that is a certain distance above the ground. The radar will reduce or avoid detection of the bottom area 420 outside the target area, thereby further avoiding misdetection and miscontrol caused by the activities of small animals or sweepers in the bottom area, thereby further improving the reliability of interactive control of home appliances based on radar.

[0069] Furthermore, in an embodiment, the method may also include: obtaining detection area adjustment information; and controlling the radar to adjust the target area in the beam focus of the antenna array according to the detection area adjustment information.

[0070] The detection area adjustment information is reference information for adjusting the target area in the beam focus of the antenna array. In one example, the detection area adjustment information can be the location information of a new target area input or selected by the user. For example, the user can open the space map in the settings page and edit or select a new target area in the space map. In one example, the detection area adjustment information can be the size information of an interference object (such as an animal or a sweeper) in the space detected by other sensors or other devices.

[0071] After obtaining the detection area adjustment information, the radar is controlled to adjust the target area where the beam of the antenna array is concentrated according to the detection area adjustment information, so that the radar can detect a more reasonable target area, further improving the control reliability of home appliances.

[0072] In one embodiment, controlling the radar to adjust the target area in the beam focus of the antenna array according to the detection area adjustment information may include: determining an adjustment length of the phase delay line between the antennas according to the detection area adjustment information; and controlling the radar to adjust the length of the phase delay line between the antennas in the antenna array according to the adjustment length of the phase delay line between the antennas to adjust the target area.

[0073] In one method, determining the adjustment length of the phase delay line between antennas based on the detection area adjustment information may include: the detection area adjustment information is the location information of the new target area, the difference between the location information of the new target area and the location information of the original target area can be calculated, and the predetermined adjustment length corresponding to the difference can be queried from the first preset adjustment table as the adjustment length of the phase delay line between antennas, or the adjustment length of the phase delay line between antennas can be calculated according to the difference through a preset formula.

[0074] Optionally, in other methods, the adjustment length of the phase delay line between antennas can be determined based on the detection area adjustment information, which may include: the detection area adjustment information is the size information of an interference object in space (such as an animal or a sweeper), and the position information of a new target area that does not interfere with the interference object can be determined based on the size information, and the difference between the position information of the new target area and the position information of the original target area can be further calculated, and the predetermined adjustment length corresponding to the difference can be queried from the first preset adjustment table as the adjustment length of the phase delay line between the antennas, or the adjustment length of the phase delay line between the antennas can be calculated according to the difference through a preset formula.

[0075] A mechanism for adjusting the length of the phase delay line between antennas in the antenna array can be set in the radar. After determining the adjusted length of the phase delay line between the antennas according to the detection area adjustment information, the radar can be controlled to adjust the length of the phase delay line between the antennas in the antenna array through the mechanism according to the adjusted length of the phase delay line between the antennas, thereby effectively suppressing or reducing the gain of other areas outside the new target area, so that the beam of the antenna array is concentrated on the new target area for detection.

[0076] In one embodiment, controlling the radar to adjust the target area in the beam focus of the antenna array according to the detection area adjustment information may include: determining the adjustment amplitude and phase of the antennas in the antenna array according to the detection area adjustment information; and controlling the radar to adjust the amplitude and phase of the antennas in the antenna array according to the adjustment amplitude and phase of the antennas in the antenna array to adjust the target area.

[0077] In one method, determining the adjustment amplitude and phase of the antenna in the antenna array based on the detection area adjustment information may include: the detection area adjustment information is the location information of the new target area, the difference between the location information of the new target area and the location information of the original target area can be calculated, and the predetermined adjustment amplitude and phase corresponding to the difference can be queried from a second preset adjustment table as the adjustment amplitude and phase of the antenna in the antenna array, or the adjustment amplitude and phase of the antenna in the antenna array can be calculated according to the difference through a preset formula.

[0078] Optionally, in other methods, the adjustment length of the phase delay line between antennas can be determined based on the detection area adjustment information, which may include: the detection area adjustment information is the size information of the interference object in the space (such as an animal or a sweeper), and the position information of a new target area that does not interfere with the interference object can be determined based on the size information, and the difference between the position information of the new target area and the position information of the original target area can be further calculated, and the predetermined adjustment amplitude and phase corresponding to the difference can be queried from the second preset adjustment table as the adjustment amplitude and phase of the antenna in the antenna array, or the adjustment amplitude and phase of the antenna in the antenna array can be calculated according to the difference through a preset formula.

[0079] According to the adjustment amplitude and phase of the antenna in the antenna array, the radar can be controlled to adjust the amplitude and phase of the antenna in the antenna array, suppressing or reducing the gain of other areas outside the new target area, so that the beam of the antenna array is concentrated on the new target area for detection.

[0080] In one embodiment, controlling the radar to adjust the target area in the beam focus of the antenna array according to the detection area adjustment information may include: determining a rotation angle of the radar according to the detection area adjustment information; and controlling the radar to rotate to adjust the target area according to the rotation angle of the radar.

[0081] In one method, determining the rotation angle of the radar based on the detection area adjustment information may include: the detection area adjustment information is the position information of the new target area, the difference between the position information of the new target area and the position information of the original target area can be calculated, and the predetermined rotation angle corresponding to the difference can be queried from a third preset adjustment table as the rotation angle of the radar, or the rotation angle of the radar can be calculated according to the difference through a preset formula.

[0082] Optionally, in other methods, the adjustment length of the phase delay line between antennas can be determined based on the detection area adjustment information, which may include: the detection area adjustment information is the size information of the interference object in the space (such as an animal or a sweeper), and the position information of a new target area that does not interfere with the interference object can be determined based on the size information, and the difference between the position information of the new target area and the position information of the original target area can be further calculated, and the predetermined rotation angle corresponding to the difference can be queried from the third preset adjustment table as the rotation angle of the radar, or the rotation angle of the radar can be calculated according to the difference through a preset formula.

[0083] The radar can be arranged on a rotating base, and the rotating base can be controlled to rotate the radar according to the rotation angle of the radar, so that the beam of the antenna array is concentrated on a new target area for detection.
