Description

Technical Field

[0002] Currently, refrigerators have effectively improved the user experience by integrating displays and touchscreens, and have made significant progress in both displayed content and automation. For example, they can not only intuitively display basic information such as temperature, humidity, and time, but also clearly show the internal storage status of the refrigerator, and usually can automatically turn the screen on and off. However, this also makes refrigerator displays more prone to unnecessary power consumption and shortened display lifespan, and also poses corresponding risks to user privacy.

[0030] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0031] The accompanying drawings, which are incorporated in and form a part of this specification, illustrate embodiments consistent with this disclosure and, together with the description, serve to explain the principles of this disclosure.

Detailed Implementation

[0033] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0034] It should be noted that all actions involving the acquisition of signals, information, or data in this disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the location is situated, and with authorization from the owner of the relevant device.

[0035] Before detailing the specific embodiments of this disclosure, the application scenarios of this disclosure are first explained as follows. This disclosure can be applied to the control process of a refrigerator display screen. With the development of detection technology, infrared sensors, cameras, and millimeter-wave radar technologies enable refrigerators to accurately detect the presence and actions of people. Furthermore, refrigerators effectively improve the user's interactive experience by integrating a display screen and a touch screen. However, in actual applications, the refrigerator display screen often automatically lights up when there is obstruction or when a pet passes by the refrigerator. It also automatically lights up when strangers or visitors approach. This not only increases the power consumption of the refrigerator display screen but also hinders the extension of its lifespan. Moreover, it can easily leak the privacy of refrigerator users and lead to a poor user experience.

[0036] To address the aforementioned technical issues, this disclosure provides a refrigerator display screen control method, device, storage medium, and program product. This refrigerator display screen control method can detect whether a target user exists within a first preset distance range of the refrigerator when the user's current home state is determined to be the first home state, i.e., when the user is at home. This effectively reduces the energy consumption of the refrigerator display screen. Furthermore, when a target user exists within the first preset distance range of the refrigerator, the method can control the refrigerator display screen to light up based on the target user's first posture information. This not only effectively reduces the possibility of the display screen triggering light up due to misjudgment but also effectively improves the security and privacy of the refrigerator settings.

[0037] Figure 1 This is a flowchart illustrating a refrigerator display control method according to an exemplary embodiment; as shown below. Figure 1 As shown, the refrigerator display control method may include: Step 101: Obtain the current home status information of the refrigerator user when the refrigerator display screen is off.

[0038] The current home status information is either a first home status information or a second home status information; the first home status information is used to indicate that the user is at home, and the second home status information is used to indicate that the user is away from home.

[0039] In this step, one possible implementation is as follows: obtain the current status of one or more preset associated devices; if it is determined that the current status of at least one of the preset associated devices is at home, generate the first home status information; if it is determined that the current status of all one or more preset associated devices is away from home, generate the second home status information.

[0040] It should be noted that the preset associated device can be a home appliance, such as an air conditioner, light bulb, television, or air purifier; fitness equipment, such as a treadmill, exercise bike, or rowing machine; or a terminal device or wearable device, such as a tablet, mobile phone, watch, smart band, or earphones. The current status of the preset association can be "on," "running," the connection status of the terminal device to the preset wireless network, or the status of the current location displayed by the location function as belonging to the target location.

[0041] Another possible implementation is as follows: the refrigerator is connected to a target application, which is used to receive the appliance control mode set by the user, the appliance control mode including an away mode and a home mode, and to obtain the current home status information of the refrigerator user, including: obtaining the appliance control mode set by the user in the target application; generating the first home status information when the appliance control mode is the home mode; and generating the second home status information when the appliance control mode is the away mode.

[0042] For example, this target application is used to intelligently control multiple appliances pre-bound by the user. For instance, it can control the on / off state, mode selection, and temperature adjustment of a pre-bound air conditioner, as well as control pre-bound televisions and lights. When the appliance control mode is set to "Home Mode" on the target application, the pre-bound appliances can be controlled according to the control parameters for that mode. When the appliance control mode is set to "Away Mode" on the target application, the pre-bound appliances can be controlled according to the control parameters for that mode. For example, in "Home Mode," the air conditioner's control parameters include: On status: On, Time: January-April, Mode: Heating, Temperature: 26 degrees Celsius; May-September, Mode: Cooling, Temperature: 25 degrees Celsius. In "Home Mode," the air purifier's control parameters include: On status: On, Mode: Sterilization, Fan speed: Automatic. In "Home Mode," the indoor lights' control parameters include: Living room lights on. In the "Away from Home" mode, the control parameters for the air conditioner include: On status: Off. In the "Away from Home" mode, the control parameters for the air purifier include: On status: Off. In the "Away from Home" mode, the control parameters for the indoor lights include: Living room light off, bedroom light off, dining room light off, and bathroom light off.

[0043] Step 102: If the current home status information is determined to be the first home status information, and if a target user is determined to exist within the first preset distance range of the refrigerator, the first pose information of the target user is obtained.

[0044] In one implementation, if a target mobile terminal is determined to exist within a first preset distance range, then a target user can be determined to exist within the first preset distance range.

[0045] The target mobile terminal can be a pre-bound target user's mobile phone, watch, tablet, bracelet, etc.

[0046] It should be noted that the presence of a target mobile terminal within the first preset distance range can be determined by using Bluetooth, mobile signal detectors, or NFC technology.

[0047] In another implementation, an infrared sensor or camera can be used to determine whether a target user exists within the first preset distance range.

[0048] The target user can be a pre-set user. When determining whether the target user exists within the first preset distance range through the camera, the camera can capture images around the refrigerator and use these images to determine whether the target user exists within the first preset distance range.

[0049] Additionally, the first pose information can be the relative position information between the target user and the refrigerator, and the user's facial orientation information. The implementation method for obtaining the target user's first pose information in step 102 can be: obtaining the relative position information between the target user and the refrigerator at a first preset sampling frequency to obtain multiple relative position information from multiple samples; obtaining the user's facial image information at a second preset sampling frequency; and determining the target user's facial orientation information based on the facial image information. The first preset sampling frequency and the second preset sampling frequency can be the same or different.

[0050] Step 103: Control the refrigerator display screen to turn on according to the first pose information.

[0051] The first pose information may include the relative position information of the target user and the refrigerator and the user's facial orientation information; the facial orientation information includes facing the refrigerator and not facing the refrigerator.

[0052] It should be noted that one implementation method for obtaining this facial orientation information is to input the captured facial image into a preset facial orientation recognition model to obtain the facial orientation information output by the facial orientation recognition model. This facial orientation recognition model can be a pre-trained neural network model. The training process of the facial orientation recognition model can include acquiring multiple image sample data, including labeled data showing faces facing and not facing the refrigerator. Using these multiple image sample data as training data, a preset initial model is trained to obtain the facial orientation recognition model.

[0053] In some embodiments, if it is determined that the distance between the target user and the refrigerator has decreased based on the plurality of relative position information, and if it is determined that the face orientation information indicates that the user is facing the refrigerator, then the refrigerator display screen is controlled to turn on.

[0054] In other embodiments, if it is determined that the distance between the target user and the refrigerator has decreased based on the plurality of relative position information, and if it is determined that the face orientation information is not towards the refrigerator, then the refrigerator display screen is controlled to turn off.

[0055] In some other embodiments, if it is determined from the plurality of relative position information that the distance between the target user and the refrigerator increases or remains unchanged, the refrigerator display screen is turned off.

[0056] The above technical solution can detect whether a target user exists within a first preset distance range of the refrigerator when the user's current home state is determined to be the first home state, i.e., when the user is at home. This can effectively reduce the energy consumption of the refrigerator display screen. Furthermore, when a target user exists within the first preset distance range of the refrigerator, the refrigerator display screen can be controlled to light up based on the target user's first posture information. This not only effectively reduces the possibility of the display screen being triggered due to misjudgment, but also effectively improves the security and privacy of the refrigerator settings.

[0057] Figure 2 It is based on Figure 1 The illustrated embodiment shows a flowchart of a refrigerator display screen control method, as follows: Figure 2 As shown, Figure 1 The step 101 of obtaining the current home status information of the refrigerator user may include: Step 1011: Obtain the current status of one or more preset associated devices.

[0058] In one embodiment, the one or more preset associated devices include one or more home appliances, which are connected to the refrigerator via a target application.

[0059] This step can send a target request instruction to the target application, and the target application, in response to receiving the target request instruction, obtains the current status of each home appliance.

[0060] The target application is used to collect the current status of one or more home appliances and send the current status to the target server. After the refrigerator display screen sends a target request instruction to the target application, the target application responds to receiving the target request instruction by sending a current status acquisition request for each home appliance to the target server. After receiving the acquisition request, the target server sends the current status of the home appliance to the refrigerator display screen.

[0061] In another embodiment, the one or more preset associated devices include a mobile terminal, and the current state includes a state of accessing the target wireless local area network and a state of not accessing the wireless local area network; it can be obtained whether the mobile terminal is in the state of accessing the target wireless local area network.

[0062] It should be noted that the target wireless LAN can be the wireless LAN of the location where the refrigerator is located. For example, if the refrigerator is in the living room of user A's house, the target wireless LAN can be the LAN of user A's living room.

[0063] Step 1012: If it is determined that at least one of the preset associated devices is currently in a home state, the first home state information is generated.

[0064] In one possible implementation, for each household appliance, target attribute information of the current state of the household appliance can be obtained; if the target attribute information is determined to be a home state attribute, the current state of the household appliance is determined to be a home state; if the target attribute information is determined to be a non-home state attribute, the current state of the household appliance is determined to be a non-home state.

[0065] For example, when the household appliance is an air conditioner or an air purifier, if the current state is the operating state, meaning the target attribute information for the operating state is the "at home" state attribute, then the current state of the air conditioner or air purifier is determined to be the "at home" state. When the household appliance is a living room light, if the current state of the living room light is the "on" state, meaning the target attribute for the "on" state is the "at home" state attribute, then the current state of the living room light is determined to be the "at home" state. When the household appliance is a robotic vacuum cleaner, the robotic vacuum cleaner's states include sweeping, mopping, cleaning, charging, and off states. The target attribute information for the sweeping, mopping, and cleaning states can be the "at home" state attribute, while the target attribute information for the charging and off states can be the "not at home" state attribute. Therefore, if the current state of the robotic vacuum cleaner is determined to be sweeping, mopping, or cleaning, then the current state of the robotic vacuum cleaner is determined to be the "at home" state.

[0066] In another embodiment, the one or more preset associated devices include a mobile terminal, and the current state includes a state of accessing the target wireless local area network and a state of not accessing the wireless local area network; determining that the current state of at least one of the one or more preset associated devices belongs to the home state includes: if the current state of the mobile terminal is the state of accessing the target wireless local area network, determining that the current state of the mobile terminal belongs to the home state.

[0067] Specifically, if it is determined that the wireless local area network currently connected to by the mobile terminal is the target wireless local area network, then the current state of the mobile terminal is determined to be the state of accessing the target wireless local area network.

[0068] Step 1013: If it is determined that the current status of one or more preset associated devices is "away from home", the second home status information is generated. Steps 1011 to 1013 above can generate first home status information or second home status information based on the current status of one or more preset associated devices, and can provide reliable data basis for the refrigerator display screen to be on or off.

[0069] Optionally, Figure 3 It is based on Figure 1 The flowchart of another refrigerator display control method shown in the embodiment is as follows: Figure 3 As shown, Figure 1 The step 101 of obtaining the current home status information of the refrigerator user may further include: Step 1014: Obtain the appliance control mode set by the user in the target application.

[0070] The refrigerator is connected to a target application, which receives user-defined appliance control modes, including an away mode and a home mode.

[0071] Step 1015: If the appliance control mode is home mode, generate the first home status information.

[0072] Step 1016: If the appliance control mode is the away-from-home mode, generate the second home status information.

[0073] Steps 1014 to 1016 above can generate first home status information or second home status information based on the appliance control mode set by the user in the target application, and can provide reliable data basis for the refrigerator display screen to be on or off.

[0074] Figure 4 It is based on Figure 1 The flowchart of another refrigerator display control method shown in the embodiment is as follows: Figure 4 As shown, the refrigerator display control method may further include: Step 104: If it is determined that there is no target user within the first preset distance range of the refrigerator, the identity authentication interface is displayed when the user's touch operation is detected.

[0075] For example, if the target users of the refrigerator are family member A and family member B, and it is determined that family member A and family member B do not exist within the first preset distance range, but it is determined that the user's touch operation is collected, the identity authentication interface can be displayed.

[0076] Step 105: Obtain the identity authentication message entered by the user through the identity authentication interface.

[0077] The identity verification message is used to verify the user's identity and may include username, nickname, account, user password, PIN code, verification code, etc. It may also obtain the user's biometric information, such as fingerprint, iris, facial features, etc.

[0078] Step 106: If the identity verification is successful based on the identity authentication message, obtain the second pose information of the current user. If the current user is determined to be away from the refrigerator based on the second pose information, control the refrigerator display screen to turn off.

[0079] Specifically, if the authentication message is a user password, and the user's entered password matches the pre-set password, then authentication is successful. If the authentication message is the user's biometric information, and the user's first biometric information entered through the authentication interface matches the user's pre-set second biometric information, then authentication is successful.

[0080] Additionally, the second pose information can be the relative position information between the current user and the refrigerator, and the current user's facial orientation information; the facial orientation information includes facing the refrigerator and not facing the refrigerator. The process of obtaining this facial orientation information can involve inputting a captured facial image into a preset facial orientation recognition model to obtain the facial orientation information output by the model. This facial orientation recognition model can be a pre-trained neural network model. The training process of this model can include acquiring multiple image sample data, which includes labeled data indicating whether the face is facing or not facing the refrigerator. Using these multiple image sample data as training data, a preset initial model is trained to obtain the facial orientation recognition model.

[0081] It should be noted that when controlling the refrigerator display screen based on the second pose information, the following four implementation methods can be included: Method 1: If the distance between the current user and the refrigerator increases based on the multiple relative position information, the refrigerator display screen is turned off; Method 2: If the distance between the current user and the refrigerator decreases based on the multiple relative position information, and the facial orientation information indicates that the user is facing the refrigerator, the refrigerator display screen is turned on; Method 3: If the current user's facial orientation information indicates that the user is not facing the refrigerator, the refrigerator display screen is turned off; Method 4: If the distance between the current user and the refrigerator remains unchanged based on the multiple relative position information, the refrigerator display screen is turned off.

[0082] The above technical solution can obtain the user's authentication message through the authentication interface for users other than the pre-set target users. If the authentication is successful, the refrigerator display screen can be controlled according to the second pose information of the current user. This can effectively prevent the refrigerator display screen from automatically turning on for strangers, thereby effectively improving the privacy and security of the refrigerator display screen.

[0083] Figure 5This is a block diagram illustrating a refrigerator display control device according to an exemplary embodiment of this disclosure; as shown below. Figure 5 As shown, the refrigerator display screen control device may include: The first acquisition module 501 is configured to acquire the current home status information of the refrigerator user when the refrigerator display screen is in a screen-off state. The current home status information is either first home status information or second home status information. The first home status information is used to indicate that the user is at home, and the second home status information is used to indicate that the user is away from home. The first determining module 502 is configured to, when determining the current home status information as the first home status information, if it is determined that there is a target user within the first preset distance range of the refrigerator, obtain the first pose information of the target user. The control module 503 is configured to control the refrigerator display screen to light up based on the first pose information.

[0084] The above technical solution can detect whether a target user exists within a first preset distance range of the refrigerator when the user's current home state is determined to be the first home state, i.e., when the user is at home. This can effectively reduce the energy consumption of the refrigerator display screen. Furthermore, when a target user exists within the first preset distance range of the refrigerator, the refrigerator display screen can be controlled to light up based on the target user's first posture information. This not only effectively reduces the possibility of the display screen being triggered due to misjudgment, but also effectively improves the security and privacy of the refrigerator settings.

[0085] Optionally, the first acquisition module 501 is configured to: Get the current status of one or more preset associated devices; If it is determined that the current state of at least one of the preset associated devices is a home state, the first home state information is generated.
