Description

Home appliance control methods, devices, storage media and home appliances

[0001] This application claims priority to Chinese Patent Application No. 202510107822.8, filed on January 22, 2025, entitled "Control Method, Apparatus, Storage Medium and Household Appliance", the entire contents of which are incorporated herein by reference. Technical Field

[0003] Intelligent interactive control of home appliances (such as televisions and refrigerators) is becoming increasingly common. One related technology involves using radar (such as millimeter-wave radar) on these appliances to sense the environment and control them based on the detected information. Currently, in home environments, radar detection often detects movement of objects like robot vacuums or pets, triggering erroneous control of these appliances.

[0004] To address this, related technologies typically control the radar's detection limit (i.e., the maximum detection range of the radar at a set sensitivity) by adjusting the radar's sensitivity, thereby reducing false control of home appliances. However, this method only adjusts the radar's maximum detection range, and false detections leading to false control still frequently occur. Technical issues

[0038] Implementation methods of this application

[0039] The present disclosure will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the embodiments provided herein are merely illustrative of the present disclosure and are not intended to limit the present disclosure. Furthermore, the embodiments provided below are some embodiments for implementing the present disclosure, and not all embodiments for implementing the present disclosure. Unless otherwise specified, the technical solutions described in the embodiments of the present disclosure can be implemented in any combination.

[0040] It should be noted that, in the embodiments of this disclosure, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a method or apparatus that includes a list of elements includes not only the elements expressly described, but also other elements not expressly listed, or elements inherent to implementing the method or apparatus. Without further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of other related elements (e.g., steps in the method or units in the apparatus, such as portions of circuitry, processors, programs, or software, etc.) in the method or apparatus that includes that element.

[0041] For example, the home appliance control method provided in this disclosure includes a series of steps, but the home appliance control method provided in this disclosure is not limited to the steps described. Similarly, the home appliance control device provided in this disclosure includes a series of units, but the device provided in this disclosure is not limited to the units explicitly described, but may also include units that need to be set up for obtaining relevant information or processing based on information.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure.

[0043] It is understood 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 must comply with the relevant laws, regulations and standards of the relevant countries and regions.

[0044] Figure 1 schematically illustrates a flowchart of a home appliance control method according to an embodiment of this application. The executing entity of this home appliance control method can be the home appliance itself with processing capabilities or the control terminal of the home appliance. Home appliances include, for example, televisions, refrigerators, washing machines, etc.; the control terminal of the home appliance is a terminal that can control the home appliance, such as a remote control or other dedicated control device. Specifically, in one embodiment of this application, the executing entity of the home appliance control method is a television, and the controlled home appliance is the television itself.

[0045] Furthermore, as shown in Figure 1, the home appliance control method may include steps S110 to S130.

[0046] Step S110: Set trigger conditions for the radar corresponding to the home appliance to obtain the custom trigger conditions of the radar. The custom trigger conditions include at least one custom trigger range and a corresponding interactive command. Each custom trigger range is less than or equal to the radar's radar limit detection range.

[0047] Step S120: Receive a trigger signal corresponding to the target trigger range sent by the radar. The trigger signal is issued by the radar when it detects a detection signal that meets a predetermined state within the target trigger range. The target trigger range is one or more of the at least one custom trigger range.

[0048] Step S130: Determine the interactive instruction that matches the target trigger range corresponding to the trigger signal, and control the home appliance based on the interactive instruction.

[0049] By having users perform setting operations on the control terminal of home appliances, or by having users perform setting operations on home appliances, or by having home appliances or control terminals perform automated judgment and setting operations, the trigger conditions for the radar corresponding to the home appliances can be set, thus obtaining the custom trigger conditions for the radar.

[0050] The custom trigger conditions include at least one custom trigger range (e.g., 1 or 5) and the corresponding interactive instruction. Each custom trigger range can correspond to one interactive instruction, or a combination of multiple custom trigger ranges can correspond to one interactive instruction.

[0051] After setting the custom trigger conditions, 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 that a detection signal that meets the predetermined state has appeared within the target trigger range. The target trigger range can be one or more of the aforementioned custom trigger ranges.

[0052] For example, trigger signal 1 is issued when a detection signal matching a predetermined state appears within custom trigger range 1. Trigger signal 1 indicates that a detection signal matching a predetermined state has appeared within custom trigger range 1. Trigger signal 2 is issued when detection signals matching a predetermined state appear within custom trigger range 2 and custom trigger range 3. Trigger signal 2 indicates that detection signals matching a predetermined state have appeared within both custom trigger range 2 and custom trigger range 3.

[0053] Each custom trigger range is less than or equal to the radar's maximum detection range, which is the radar's maximum detection range at the currently set sensitivity. If a detection signal is detected within the range of the custom trigger range but less than the radar's maximum detection range, the radar will not issue a trigger signal.

[0054] After receiving the trigger signal corresponding to the custom trigger range sent by the radar, the executing entity can further determine that the trigger signal indicates that a detection signal that meets the predetermined state has appeared within the target trigger range. Furthermore, it can determine the interactive command corresponding to the target trigger range (i.e., a certain custom trigger range or a combination of multiple custom trigger ranges) based on the custom trigger conditions.

[0055] Interactive commands are instructions used to interactively control home appliances. Examples of interactive commands include turning the appliance on / off, changing a channel, and adjusting the volume. The executing entity can then control the home appliance based on these interactive commands.

[0056] In this embodiment of the application, by setting trigger conditions for the radar corresponding to the home appliance, custom trigger conditions are set for the radar. These custom trigger conditions include at least one custom trigger range and a corresponding interactive command. The radar can detect and send a trigger signal according to the custom trigger range. The trigger signal further triggers the interactive command to control the home appliance. This can avoid false detection of areas outside the custom trigger range that could lead to false control. Thus, it can reliably meet personalized needs for interactive control of home appliances based on radar, effectively improving the overall reliability of radar-based interactive control of home appliances and enhancing the user experience.

[0057] The following describes further optional embodiments of the steps performed when controlling home appliances according to the embodiment shown in Figure 1.

[0058] In one embodiment, setting trigger conditions for the radar corresponding to the home appliance to obtain custom trigger conditions for the radar may include: detecting a marker through the radar to record at least one wandering boundary of the marker, with each wandering boundary serving as a custom trigger range; and setting an interactive command corresponding to each custom trigger range or a combination of multiple custom trigger ranges.

[0059] During the setting of trigger conditions, a marker (such as a human body) can move along the required boundaries. By detecting the marker with radar, at least one moving boundary (i.e., movement trajectory) of the marker can be recorded. The marker can move to form one or more moving boundaries.

[0060] Each wander boundary is treated as a custom trigger range, and the range data (i.e., boundary data) of each custom trigger range can be stored in the processor storage unit such as an SOC in the form of a table. For example, as shown in Figure 2, a custom trigger range 220 is detected and recorded before the location of radar 210. This custom trigger range 220 can be recorded in a table as "θ∈(-90°, 90°) range, r≤f(r,θ)", where θ is the angle between the line connecting each point on the boundary of the custom trigger range to the radar and the radar's forward direction, and r is the distance from the radar to each point on the boundary of the custom trigger range.

[0061] Furthermore, users can configure interactive commands for each custom trigger range by associating them with specific settings. For example, if custom trigger range 1, custom trigger range 2, and custom trigger range 3 are set, interactive command 1 can be set for custom trigger range 1, interactive command 2 for custom trigger range 2, and interactive command 3 for custom trigger range 3. In this case, when a detection signal matching the predetermined state is detected within custom trigger range 1, trigger signal 1 is issued, and the target trigger range corresponding to trigger signal 1 can be determined to be custom trigger range 1, and its matching interactive command is interactive command 1.

[0062] Furthermore, users can configure interaction commands corresponding to combinations of multiple custom trigger ranges through command association settings. For example, if custom trigger range 1, custom trigger range 2, and custom trigger range 3 are set, interaction command 4 can be set for the combination of custom trigger range 1 and custom trigger range 2. In this case, after trigger signal 4 is issued when detection signals that meet the predetermined state are detected 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 matching interaction command is interaction command 4.

[0063] Furthermore, in one embodiment, setting trigger conditions for the radar corresponding to the home appliance to obtain custom trigger conditions for the radar may include: acquiring at least one user-defined boundary data, each boundary data serving as a custom trigger range; and setting an interactive command corresponding to each custom trigger range or a combination of multiple custom trigger ranges.

[0064] Users can directly define one or more boundary data (such as tabular data or boundary functions) using tools like table or formula editors as needed, thereby obtaining at least one user-defined boundary data. Each boundary data can be stored as a custom trigger range in the processor's memory unit. Simultaneously, interactive instructions can be set for each custom trigger range, or interactive instructions can be set for a combination of multiple custom trigger ranges.

[0065] In a further embodiment, setting trigger conditions for the radar corresponding to the home appliance to obtain custom trigger conditions for the radar may include: acquiring historical interactive control data of the home appliance; analyzing the historical interactive control data and setting custom trigger conditions for the radar.

[0066] Historical interactive control data refers to data recorded when users have controlled home appliances in the past. This data, generated within a predetermined timeframe, can be obtained from the log files. Historical interactive control data may include the user's location in space and the interactive commands issued to the home appliances from that location.

[0067] By analyzing historical interactive control data using fine-tuned large language models, custom trigger conditions for the radar can be intelligently set according to users' interactive control habits, further enhancing the control experience of home appliances. Custom trigger conditions for the same radar include at least one custom trigger range and a corresponding interactive command (i.e., interactive commands can be set for each custom trigger range or a combination of multiple custom trigger ranges), with each custom trigger range being less than or equal to the radar's maximum detection range.

[0068] In one embodiment, the radar includes an antenna array comprising multiple antennas connected to adjacent antennas via phase delay lines, and the multiple antennas are arranged longitudinally in a vertical plane perpendicular to the ground. Before receiving the trigger signal corresponding to the target trigger range transmitted by the radar, the method further includes: controlling the beam of the antenna array to focus on a target area in space for detection, wherein the target area refers to an area in space above a certain distance from the ground, and the radar emits a corresponding trigger signal when it detects a detection signal conforming to a predetermined state within the target trigger range of the target area.

[0069] Referring to Figure 3, adjacent antennas in the antenna array 310 (such as antennas ANT1 and ANT2 as shown in Figure 3) are connected by phase delay lines 320, and the multiple antennas are arranged longitudinally in a vertical plane perpendicular to the ground. In this way, as shown in Figure 4, the antennas in the antenna array 310 can be beamformed in the vertical plane. By setting the installation position of the radar or adjusting the antennas, the beam of the antenna array can be conveniently and flexibly focused on the target area in space for detection, while reducing or avoiding detection of areas outside the target area.

[0070] The target area refers to a region in space that is a certain distance above the ground. For example, as shown in Figure 4, the target area is the 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 false detection and false control caused by the activities of small animals or sweeping robots in the bottom area, thereby further improving the reliability of interactive control of home appliances based on radar.

[0071] In a further embodiment, the method may also include: acquiring detection area adjustment information; and controlling the radar to adjust the target area of ​​the antenna array beam concentration according to the detection area adjustment information.

[0072] The detection area adjustment information serves as reference information for adjusting the target area used in the beam concentration of the antenna array. In one example, this detection area adjustment information could be the location information of a new target area input or selected by the user; for instance, the user could open a spatial map in the settings page and edit or select a new target area within it. In another example, the detection area adjustment information could be the size information of interfering objects (such as animals or robot vacuums) detected in space by other sensors or similar devices.

[0073] After obtaining the detection area adjustment information, the radar adjusts the target area of ​​the antenna array beam concentration according to the detection area adjustment information, so that the radar can detect a more reasonable target area and further improve the reliability of home appliance control.

[0074] In one embodiment, controlling the radar to adjust the target area of ​​the antenna array beam concentration based on the detection area adjustment information may include: determining the adjustment length of the phase delay line between the antennas based on 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 based on the adjustment length of the phase delay line between the antennas, so as to adjust the target area.

[0075] In one approach, 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 being the location information of a new target area; calculating the difference between the location information of the new target area and the original target area; and querying the predetermined adjustment length corresponding to the difference from a first preset adjustment table as the adjustment length of the phase delay line between antennas; or calculating the adjustment length of the phase delay line between antennas based on the difference using a preset formula.

[0076] Optionally, in other methods, 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 being the size information of an interfering object (e.g., an animal or a robot vacuum cleaner) in space; the location information of a new target area that does not interfere with the interfering object can be determined based on this size information; furthermore, 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 retrieved from a 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 based on the difference using a preset formula.

[0077] A mechanism can be set in the radar to adjust the length of the phase delay line between the antennas in the antenna array. After determining the adjustment length of the phase delay line between the antennas based on 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 this mechanism, effectively suppressing or reducing the gain of other areas outside the new target area, so that the beam of the antenna array is concentrated in the new target area for detection.

[0078] In one embodiment, controlling the radar to adjust the target area of ​​the antenna array beam concentration based on the detection area adjustment information may include: determining the adjustment amplitude and phase of the antennas in the antenna array based on the detection area adjustment information; and controlling the radar to adjust the amplitude and phase of the antennas in the antenna array based on the adjustment amplitude and phase of the antennas in the antenna array to adjust the target area.

[0079] In one approach, 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 being the location information of a new target area; calculating the difference between the location information of the new target area and the original location information of the target area; and querying the predetermined adjustment amplitude and phase corresponding to the difference from a second preset adjustment table as the adjustment amplitude and phase of the antenna in the antenna array; or calculating the adjustment amplitude and phase of the antenna in the antenna array based on the difference using a preset formula.

[0080] Optionally, in other methods, 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 being the size information of an interfering object (e.g., an animal or a robot vacuum cleaner) in space; the location information of a new target area that does not interfere with the interfering object can be determined based on this size information; furthermore, 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 retrieved 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 based on the difference using a preset formula.

[0081] By adjusting the amplitude and phase of the antennas in the antenna array, the radar can be controlled to adjust the amplitude and phase of the antennas in the antenna array, suppress or reduce the gain of other areas outside the new target area, so that the beam of the antenna array is concentrated in the new target area for detection.

[0082] In one embodiment, controlling the radar to adjust the target area of ​​the antenna array beam concentration based on the detection area adjustment information may include: determining the rotation angle of the radar based on the detection area adjustment information; and controlling the radar to rotate to adjust the target area based on the rotation angle of the radar.

[0083] In one approach, determining the radar's rotation angle based on the detection area adjustment information may include: the detection area adjustment information being the location information of a new target area; calculating the difference between the location information of the new target area and the original location information of the target area; and querying the predetermined rotation angle corresponding to the difference from a third preset adjustment table as the radar's rotation angle; or calculating the radar's rotation angle based on the difference using a preset formula.

[0084] Optionally, in other methods, 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 being the size information of an interfering object (e.g., an animal or a robot vacuum cleaner) in space; the location information of a new target area that does not interfere with the interfering object can be determined based on this size information; furthermore, 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 rotation angle corresponding to the difference can be retrieved from the third preset adjustment table as the rotation angle of the radar; or the rotation angle of the radar can be calculated based on the difference using a preset formula.

[0085] The radar can be mounted on a rotating base. 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 focused on the new target area for detection.

The meanings of the terms used are the same as in the above-described home appliance control method, and specific implementation details can be found in the descriptions in the method embodiments.
