[0042] In order to make the purpose, technical solution and advantages of the present invention clearer and more specific, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0043] The screen-off control method described in the preferred embodiment of the present invention is as follows: Figure 1 As shown, the screen off control method includes the following steps:

[0044] Step S10: The smart refrigerator receives the user leaving home information fed back by the smart door lock, and controls the indoor camera to collect indoor image information. The user leaving home information indicates that a user has closed the door and left home.

[0045] For detailed process, please refer to Figure 2 , which is a flowchart of step S10 in the screen off control method provided by the present invention.

[0046] like Figure 2 As shown, the step S10 includes:

[0047] S11. When the smart door lock detects through the camera on the smart door lock that a user has closed the door and left home, the smart refrigerator receives the user leaving home information sent by the smart door lock;

[0048] S12: When the smart refrigerator receives the information that the user has left home, it sends a request for obtaining image information to the camera indoors, so as to request the camera indoors to collect the indoor image information within a preset area.

[0049] Specifically, the smart refrigerator of the present invention has a display screen that can be controlled by touch and display relevant information, and the display screen is arranged on the outer surface of the refrigerator door, so that the home user can watch and set it. Before the step S10, it also includes: the smart refrigerator pre-establishes a wireless communication connection with the smart door lock and at least one of the cameras in the room through an indoor local area network (such as home WIFI), and receives the information sent by the smart door lock and the camera in real time. The smart door lock is used for the home user to perform a smart door opening operation, such as the user opening the door of the smart door lock through fingerprint recognition, face recognition, password input or key unlocking. The smart door lock is provided with a camera (which can be called an external camera), which can detect the user leaving home or returning home, and can also monitor the relevant situation outside the door, such as monitoring a stranger trying to open the door, and can start an alarm or notify the user in the family; in addition, indoor cameras are also arranged at some positions in the home, such as a camera that can monitor the image within the entire living room is arranged in the living room, or a camera that monitors the image within the entire bedroom is arranged in the bedroom. The indoor camera is set in the present invention to confirm whether there are still home users in the home after the user closes the door and leaves home.

[0050] When the smart door lock detects that a user has closed the door and left home through the camera on the smart door lock (external camera), for example, after the smart door lock finds out that a user in the family has gone out through the external camera (the door locking action can be detected at the same time after the user goes out), the user leaving home information is generated, and then the user leaving home information is fed back to the smart refrigerator. The smart refrigerator receives the user leaving home information sent by the smart door lock, which means that the smart refrigerator has known that a user has left home. Then, when the smart refrigerator receives the user leaving home information, it sends a request for obtaining image information to the camera indoors. That is to say, although it is detected that a user has closed the door and left home at this time, it does not mean that all users in the family have left home. Therefore, in order to further confirm whether there are still users in the family, the smart refrigerator can request the camera indoors to collect the indoor image information in a preset area.

[0051] Step S20: the smart refrigerator receives the indoor image information sent by the camera. If it is confirmed based on the indoor image information that there is no user indoors, the display screen of the smart refrigerator is controlled to turn off.

[0052] For detailed process, please refer to Figure 3 , which is a flowchart of step S20 in the screen off control method provided by the present invention.

[0053] like Figure 3 As shown, the step S20 includes:

[0054] S21, after receiving the indoor image information sent by the indoor camera, the smart refrigerator analyzes the indoor image information through image detection to confirm the indoor user situation;

[0055] S22. If the smart refrigerator confirms that there is no user indoors based on the indoor image information, the smart refrigerator sends a screen-off instruction to the display screen to control the display screen to perform a screen-off operation.

[0056] Specifically, after the indoor camera is turned on, it collects a 360-degree panoramic image of the camera's visible range (the camera can perform 360-degree rotation and shooting, so as to collect image information within the entire range). After the camera collects the indoor image information (for example, images within the living room), it sends it to the smart refrigerator. After receiving the indoor image information sent by the camera, the smart refrigerator analyzes the indoor image information through image detection to confirm the indoor user situation, that is, the smart refrigerator determines whether there is a user in the indoor image information through image analysis (this user can be any one or more family members except those who have closed the door and left home). According to the judgment result, it can be known whether there is still a user in the family at this time, and the analysis result includes the existence of the user and the non-existence of the user.

[0057] If the smart refrigerator determines that there is no user according to the indoor image information, that is, when it is confirmed that there is no user indoors, the smart refrigerator sends a screen-off instruction to the display screen to control the display screen to perform a screen-off operation. This means that when the user detected by the smart door lock closes the door and leaves home, all family members have left home. At this time, there is no user at home, so there is no need for the display screen of the smart refrigerator to be lit. Therefore, in order to avoid wasting electricity by the display screen being in a lit state for a long time, the display screen can be controlled to turn off automatically at this time, thereby saving electricity. If the smart refrigerator determines that there is a user according to the indoor image information, that is, when it is confirmed that there is still a user indoors, the smart refrigerator still maintains a lit screen state without the need to perform a screen-off operation (no delayed screen off); further, if after a period of time (for example, 1 hour) the indoor camera detects again and finds that there is no user indoors (indicating that all family users have left home during this period), the smart refrigerator sends a screen-off instruction to the display screen to control the display screen to perform a screen-off operation.

[0058] Furthermore, if the smart door lock detects that the user has opened the door through fingerprint recognition, face recognition, password input or key unlocking (i.e., the smart door lock detects that a user has returned home, and the user has opened the door through a related door opening method), or the smart door lock detects that a user has returned home through the external camera, the smart refrigerator receives the door opening instruction information sent by the smart door lock, and if the display screen of the smart refrigerator is currently in an off-screen state, the display screen is controlled to light up, and if the display screen of the smart refrigerator is currently in a bright-screen state, no operation is performed; in this way, the display screen of the smart refrigerator can be automatically lit up when the user returns home. Regardless of the interface the user is in before the screen is turned off, the screen saver interface is entered by default after the screen is turned on, and the brightness needs to change from dark to bright when the screen is turned on.

[0059] Step S30: the smart refrigerator receives a screen-off request from a user via voice, recognizes the user's voice to obtain a voice control instruction based on the user's request, and controls the display screen of the smart refrigerator to turn off according to the voice control instruction.

[0060] For detailed process, please refer to Figure 4 , which is a flowchart of step S30 in the screen off control method provided by the present invention.

[0061] like Figure 4 As shown, the step S30 includes:

[0062] S31, when the smart refrigerator is in the screen-on state, if a preset wake-up word is received from the user, the recording function is turned on;

[0063] S32, the smart refrigerator receives the user's voice input in the recording mode, and after the recording is completed, performs voice recognition on the voice through the ASR function, and generates a voice control instruction for the user to control the screen to turn off according to semantic analysis;

[0064] S33, the smart refrigerator obtains the voice control instruction, and sends the voice control instruction to the display screen to control the display screen to perform a screen-off operation.

[0065] Specifically, the present invention can also directly control the screen-off operation of the display screen of the smart refrigerator by voice control, which can provide users with more options and higher convenience. When the smart refrigerator is in the screen-on state, if the user issues a preset wake-up word, the recording function is turned on. The reason for setting the wake-up word to turn on the recording function is to avoid the user's speech when he does not need to control the display screen by voice to affect the voice recognition of the smart refrigerator, that is, to avoid unnecessary voice recognition. For example, the wake-up word is "Xiao T Xiao T". The smart refrigerator can detect the wake-up instruction through the control system voice assistant microphone. The voice assistant detects whether the user issues "Xiao T Xiao T". If it is detected that the user issues the wake-up word "Xiao T Xiao T", the recording function is turned on. Then, the smart refrigerator receives the user's voice input within a preset time (for example, 3-5 seconds) in the recording mode. For example, at this time, the user issues "control the display screen to turn off". When the recording is completed, the ASR (Automatic Speech Recognition) is used. The smart refrigerator uses an ASR function to perform speech recognition on the speech, that is, converting the speech information into text information first, and then generating the voice control instruction that the user needs to control the screen to turn off according to semantic analysis. For example, the voice of "control the display screen to turn off" issued by the user is converted into text through the ASR function, and then the voice control instruction that can be understood by the smart refrigerator is obtained as "control the display screen to turn off" according to the meaning of the text. The smart refrigerator obtains the voice control instruction and sends the voice control instruction to the display screen to control the display screen to perform the screen turning off operation.

[0066] Of course, when the smart refrigerator is in the screen-off state, it can also receive voice control instructions from the user to control the display screen to turn on the screen, thereby controlling the display screen to switch from the screen-off state to the screen-on state.

[0067] Furthermore, when the smart refrigerator detects that there is no operation instruction on the display screen within the default timing time of the timer (for example, the default timing time of the timer is 5 minutes), the display screen is controlled to turn off the screen. That is, the display screen can be set to automatically turn off the screen according to actual conditions to avoid the display screen being in the on state for a long time without anyone using it, thereby saving power and avoiding power waste, and also improving the service life of the display screen.

[0068] Furthermore, the display screen of the smart refrigerator can also automatically detect the distance between the user and the display screen (for example, by detecting the distance between the user and the display screen through an infrared distance sensor). When it is detected that the distance between the user and the display screen is less than a preset distance threshold (for example, a preset distance threshold can be set in advance, such as 1 meter), if the display screen is in an off state at this time, then the display screen can be controlled to light up automatically.

[0069] The present invention automatically controls the display screen of the smart refrigerator to turn off when it detects that the user has left home and there is no one indoors, or directly controls the display screen to turn off according to the user's voice command, so as to avoid the display screen being in the on state for a long time. On the basis of meeting the user's needs, the present invention automatically controls the display screen to be turned off and on, which can reduce the screen's constant on time, save energy consumption, reduce electricity costs, and increase the service life of the display screen.

[0070] Furthermore, if Figure 5 As shown, based on the above-mentioned screen-off control method, the present invention also provides a smart refrigerator accordingly, and the smart refrigerator includes a processor 10, a memory 20 and a display 30.
