[0039] Example 1:

[0040] To address the problems in the related art, embodiments of the present application provide a control method, which is applied to an electronic device, such as a mobile terminal, a computer, or a server. In some embodiments, the electronic device may be a controller for a smart door lock, which controls the main lock tongue by clicking. The functions implemented by the control method provided in embodiments of the present application can be implemented by a processor of the electronic device calling program code, wherein the program code can be stored in a computer storage medium.

[0041] The embodiment of the present application provides a control method, Figure 2 A schematic diagram of the implementation flow of a control method provided in an embodiment of the present application is shown in FIG. Figure 2 Shown, including:

[0042] Step S1: When a user closes a door, image information of the user and current information on the door handle on the door are obtained.

[0043] In an embodiment of the present application, the electronic device can be connected to a facial recognition module to obtain user image information through the facial recognition module. The facial recognition module can include a camera. The electronic device can be connected to a microcurrent sensor to obtain current information on the door handle. The microcurrent sensor can be installed on the door handle and generate current information when the user touches the door handle.

[0044] In some embodiments, the user can input the user's image information and the current information on the door handle through the APP.

[0045] In some embodiments, before step S1, the method further includes:

[0046] Step S11, obtaining the switch status of the smart door lock.

[0047] In an embodiment of the present application, the electronic device can obtain the status of the motor of the smart door lock to determine the switch status of the smart door lock.

[0048] Step S12: When it is detected that the smart door lock is turned on, the face recognition module and the microcurrent sensor are started.

[0049] In an embodiment of the present application, when the door is in a closed state, the face recognition module and the microcurrent sensor are also in a closed state, and the face recognition module and the microcurrent sensor are only started when the door is in an open state.

[0050] Step S2: determining whether a face is recognized based on the image information, and determining whether the user's hand is placed on the door handle and whether the time the hand is placed on the door handle reaches a preset time based on the current information.

[0051] In an embodiment of the present application, the electronic device can input image information into a neural network model to determine whether a face is recognized, and the neural network model can be trained using sample data.

[0052] In the embodiment of the present application, whether the face is recognized is determined to determine whether the user is facing the door when closing the door.

[0053] In an embodiment of the present application, it is possible to determine whether there is a current change based on the current information; determine whether the user's hand is placed on the door handle based on whether there is a current change; obtain the duration of the changed current, and determine whether the time placed on the door handle reaches a preset duration based on the duration.

[0054] In an embodiment of the present application, if a person's hand is placed on the door handle, the microcurrent sensor will detect the change in current and determine whether the user's hand is placed on the door handle based on the change in current. The duration of the changed current can be continuously detected, and by monitoring the duration, it can be determined whether the time the hand is placed on the door handle reaches a preset time. The preset time can be configured, for example, it can be 2 seconds. In an embodiment of the present application, the user can configure the preset time through the app.

[0055] Step S3, when no face is recognized and it is determined that the time the user's hand is placed on the door handle does not reach the preset time length, control the smart door lock to execute the first locking mode, wherein, in the first locking mode, the smart door lock is locked by the oblique lock tongue of the smart door lock, and the main lock tongue of the smart door lock is not locked.

[0056] In an embodiment of the present application, if no face is recognized and it is determined that the user's hand is placed on the door handle for less than the preset time period, that is, the user closes the door and leaves directly, it can be considered that the user has no intention of locking the main lock tongue. Therefore, only the oblique lock tongue is used to lock the door, and the main lock tongue is not locked.

[0057] The present application provides a control method, which obtains user image information and current information on the door handle on the door when the user closes the door; determines whether a face is recognized based on the image information, and determines whether the user's hand is placed on the door handle and whether the time the hand is placed on the door handle reaches a preset time based on the current information; if no face is recognized and it is determined that the time the user's hand is placed on the door handle does not reach the preset time, controls the smart door lock to execute a first locking mode, wherein, in the first locking mode, the smart door lock is locked by the oblique lock tongue of the smart door lock, and the main lock tongue of the smart door lock is not locked, which can avoid the problem of automatically locking the main lock tongue every time the door is closed, causing inconvenience in opening the door, thereby improving user experience.

[0058] In some embodiments, after step S2, the method further includes:

[0059] Step S4, when a human face is recognized and / or it is determined that the time the user's hand is placed on the door handle does not reach the preset time length, control the smart door lock to execute a second locking model, wherein, in the case of the second locking model, the smart door lock is locked by the oblique lock tongue and the main lock tongue.

[0060] In an embodiment of the present application, when a human face is recognized and / or it is determined that the time the user's hand is placed on the door handle does not reach the preset time length, it can be considered that the user has the intention to lock the main lock tongue, and the smart door lock is controlled to execute a second locking model, wherein, in the case of the second locking model, the smart door lock is locked by the oblique lock tongue and the main lock tongue.

[0061] In an embodiment of the present application, the motor of the smart door lock can be controlled to turn on to drive the main lock tongue to lock.

[0062] Example 2:

[0063] Based on the aforementioned embodiments, the embodiments of the present application further provide a control method, which mainly utilizes the combination of the smart door lock face recognition module and the microcurrent human body sensor to realize the characteristic intention recognition of the user after closing the door and actively control the opening and locking control of the smart door lock motor, so as to accurately obtain the user's locking intention, avoid automatically controlling the lock to rotate the three-level main lock tongue every time the door is closed, reduce the user's waiting time to open the door, and improve the user's experience of returning home.

[0064] The smart door locks provided in the embodiments of this application all feature a multi-module communication design. They enable data transmission and communication between modules via built-in UART, I2C, SPI, and other communication buses, and can aggregate data between modules to the module's main control chip. Using a facial recognition module and a microcurrent body sensor, they proactively determine the user's intention to lock the door, enhancing the user's door opening and closing experience.

[0065] In the embodiment of the present application, after the smart lock opens the door through the door opening button of the inner lock part inside the house or manually pressing the door handle, the main control can know the user's door opening action, wait for the user to go out, execute the door closing action, and start the face recognition module. Secondly, the human body microcurrent sensor built into the outer door handle can be used to know whether the user's hand is still on the door handle at this time. Combined with the face recognition screen, it can be known whether the user is facing the door lock. When the data of the two are unified and collected in the main control chip for processing, the user's intention to close the door and lock it at this time can be judged according to the different user status at this moment, and the automatic control motor can be realized to lock the main lock tongue.

[0066] In the local embedded system of a smart door lock, the door lock device includes a camera module and a microcurrent sensor module. The microcurrent sensor module is pre-installed in the door lock handle by default and wired to the door handle. The main control chip implements basic data communication through communication methods such as, but not limited to, I2C. The communication protocol is customized according to the logic of the main control chip. The current change in the door handle can be used to determine whether the user's hand is on the door handle and the time the user's hand has been on the door handle. Facial recognition is first used to determine whether the user's face is recognized to determine whether the user is facing the door lock. The main control program then analyzes the two signals and distinguishes between different states based on the conditions. If the user is facing the door lock and their hand is on the door handle, it determines that the user needs to lock the main deadbolt. The main program then controls the door lock motor to rotate, driving the main deadbolt stepping forward, achieving automatic locking. Conversely, if the user is not facing the door lock and the two pre-set conditions for the hand on the door handle duration are not met, it is determined that the user has no intention to lock the main deadbolt, and the main control does not execute the motor control action. If the two preset conditions are in an OR relationship and one of them is met, it can be determined that the user intends to lock the main lock tongue. At this time, the door lock will execute the motor-controlled locking action. This can achieve active judgment of the user's intention to close the door and lock and execute the corresponding locking operation.

[0067] For example, when a user leaves the house, they first press the door open button or turn the doorknob from inside. The door lock's main control program then receives a signal indicating the user has unlocked the door. The facial recognition module activates according to this pre-set condition, preparing to recognize the user's face outside. Once the user exits the house and turns to face the door lock, the lock captures the user's facial image and determines that the main deadbolt is locked, automatically executing the motor-controlled locking operation. If the user's face is not detected, but the microcurrent sensor detects a change in the level of placement and no change in departure, after a pre-set time, it is determined that the user's hand remains on the handle. The microcurrent sensor sends a signal to the main control program, also determining that the user intends to lock the door, and the locking action is executed. Conversely, if neither of these pre-set conditions is met, the user is determined to have no intention to lock the main deadbolt. The door lock then does not automatically lock, and the door is closed using the latch bolt of the lock body. This allows the user to simply wait for the latch bolt to rotate before opening the door, significantly improving the user experience.

[0068] Since the judgment and recognition of human features are relatively complex, the smart door lock device system must have logic that is not limited to feature recognition and active learning algorithms, so that the smart door lock device can identify user features, and this function can be manually calibrated through the mobile phone APP client. When errors occur in recognition, manual calibration can be performed to confirm whether it is the user himself, or the user can choose whether to turn on this function.

[0069] The control method provided in the embodiment of the present application has the advantage of being able to actively identify the user's locking intention, and can provide the user with a convenient door opening, unlocking, and door closing and locking experience.
