These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0055] With the advancement of technology, the application of the Internet of Things continues to grow and develop, and smart door locks connected to the Internet of Things are gradually becoming popular. At the same time, in order to adapt to people's pursuit of convenient life, in related technologies, users can remotely control the unlocking of smart door locks through voice assistants.

[0056] Specifically, when someone knocks on the door, the user can remotely control the smart door lock to unlock through the voice assistant without approaching the smart door lock to perform the unlocking operation. However, in this remote unlocking method, the user cannot check the status in front of the door, which is less secure.

[0057] In view of this, the present disclosure provides a method for unlocking a smart door lock. In this method, the smart door lock can send a video acquired by a camera to a device with a screen, and the video includes a picture in front of the door where the smart door lock is installed. Then, the user checks the state in front of the door based on the video received by the device with a screen, thereby determining whether to open the smart door lock, which is highly secure.

[0058] The unlocking method of the smart door lock of the embodiment of the present disclosure is described in detail below in conjunction with the accompanying drawings.

[0059] Figure 1 FIG. 1 is a flow chart of a method for unlocking a smart door lock according to an exemplary embodiment of the present disclosure. The method can be executed by a smart door lock, such as Figure 1 As shown, the exemplary embodiment method may include the following steps:

[0060] In step 101, when the WiFi function of the smart door lock is turned on, based on the WiFi function, the video acquired in real time by the camera of the smart door lock is sent to at least one pre-set screen device.

[0061] The video includes a scene in front of the door where the smart door lock is installed.

[0062] The user can pre-set at least one device with a screen on the smart door lock. For example, the user can set his or her mobile phone, tablet computer, smart speaker with a screen, TV, etc. as the at least one device with a screen.

[0063] Since the power consumption of the smart door lock will increase after the WiFi function is turned on, in this example, the WiFi function can be turned on when the smart door lock determines that there is someone in front of the door. At the same time, the smart door lock can control the camera to turn on, obtain a video containing the current scene in front of the door through the camera, and send the obtained video to the at least one screen device mentioned above in real time.

[0064] The video is composed of continuous image frames, each of which is a still image in the video. When sending the video, the smart door lock can package the 5 continuous image frames into a data packet after obtaining a certain number of continuous image frames, such as 5 frames, and transmit the data packet to the aforementioned at least one screen device through the network, thereby achieving real-time transmission.

[0065] It should be noted that the network used by the aforementioned smart door lock to communicate with the device with a screen can be either a local area network or a wide area network. Take the device with a screen as an example, a mobile phone:

[0066] LAN scenario: In the user's home, the smart door lock and the mobile phone are connected to the same WiFi network. At this time, the smart door lock and the mobile phone can directly obtain each other's IP (Internet Protocol) address. In this scenario, the smart door lock can directly send the acquired video to the mobile phone based on the IP address of the mobile phone.

[0067] WAN scenario: The smart door lock is connected to the WiFi network at home. The user takes the mobile phone to another city and uses the 4G (the 4Generation mobile communication technology) network. At this time, after turning on the WiFi function, the smart door lock needs to connect to the corresponding router, and then connect to the server, and establish a p2p (Peer-to-Peer) network path between the server and the mobile phone. Then, through the established p2p network path, the acquired video is sent to the mobile phone. The process of establishing a p2p network path based on the server can be found in the introduction of the relevant technical solution, which will not be repeated here.

[0068] In summary, in the LAN scenario, the smart door lock and the mobile phone can communicate directly based on each other's IP address. In the WAN scenario, the smart door lock and the mobile phone need to establish a p2p network path with the help of a server, and then conduct subsequent communications through the established p2p network path. In other words, the unlocking method of the smart door lock disclosed in the present invention does not limit the distance between the smart door lock and the device with a screen. For the convenience of description, the LAN scenario and the WAN scenario are no longer distinguished in the subsequent embodiments.

[0069] In step 102, after receiving an unlocking instruction sent by a target screen device among the at least one screen device based on the received video, the smart door lock is opened based on the unlocking instruction.

[0070] After the smart door lock sends the acquired video to the aforementioned at least one screen device, the user can view the video through the aforementioned at least one screen device and understand the identity of the visitor in front of the door through the video. When it is determined to open the smart door lock, the at least one screen device sends an unlocking instruction to the smart door lock. In this example, the screen device that sends the unlocking instruction can be determined as the target screen device.

[0071] After receiving the unlocking instruction sent by the aforementioned target screen device, the smart door lock can open the smart door lock based on the unlocking instruction.

[0072] In the unlocking method of the smart door lock provided by the embodiment of the present disclosure, the smart door lock can send the video acquired in real time by the camera of the smart door lock to at least one pre-set screen device based on the WiFi function when it detects that its own WiFi function is in the turned-on state. Then, after receiving the unlocking instruction sent by the target screen device among the at least one screen device based on the received video, the smart door lock is opened based on the unlocking instruction. Through the unlocking method of the smart door lock provided by the embodiment of the present disclosure, the user can receive the video sent by the smart door lock through the screen device, check the identity of the visitor in front of the door where the smart door lock is installed through the video, and then determine whether to open the smart door lock, which has high security.

[0073] Figure 2 FIG. 1 is a flowchart of another method for unlocking a smart door lock according to an exemplary embodiment of the present disclosure, and the method is also executed by the smart door lock. In this embodiment, the same steps as those in the previous embodiment will be briefly described and will not be described in detail. For details, please refer to any of the previous embodiments. Figure 2 As shown, the exemplary embodiment method may include the following steps:

[0074] In step 201, when it is detected that the doorbell is pressed, and / or it is detected that the target object stays in front of the smart door lock for a preset time, the WiFi function is turned on.

[0075] In an optional example, when the smart door lock detects that the doorbell is pressed, the WiFi function can be turned on.

[0076] The doorbell may be a doorbell of the smart door lock itself, in which case the smart door lock can automatically detect whether the doorbell is pressed. Alternatively, the doorbell may be a separate doorbell, in which case the separate doorbell needs to be connected to the smart door lock via WiFi or Bluetooth. When the doorbell is pressed, a message indicating that the doorbell is pressed may be sent to the smart door lock via WiFi or Bluetooth.

[0077] In another optional example, when the smart door lock detects that the target object stays in front of the smart door lock for a preset time, the WiFi function can be turned on.

[0078] The smart door lock can carry an infrared human body sensor. When the infrared human body sensor detects a change in temperature or heat source, it determines that there is a target object in front of the smart door lock, and the target object can be, for example, a person. Then, when the infrared human body sensor detects that the target object stays in front of the smart door lock for a preset time, such as 10 seconds, the smart door lock can turn on the WiFi function.

[0079] To avoid misjudgment, when the infrared human body sensor detects a change in temperature or heat source, the smart door lock can also control the camera to turn on and obtain a picture containing the scene outside the door. Then, the picture is subjected to portrait detection to determine whether there is someone outside the door at this time. When the portrait detection result shows that there is someone outside the door and the length of stay reaches the preset time, the smart door lock can turn on the WiFi function.

[0080] In another optional example, in order to further reduce the probability of misjudgment, the smart door lock can turn on the WiFi function after detecting that the target object has stayed in front of the smart door lock for a preset time and the doorbell has been pressed.

[0081] In step 202, a notification message is sent to at least one device with a screen based on the WiFi function.

[0082] The notification message is used to indicate that a target object exists in front of the smart door lock. The at least one device with a screen may include, for example, a mobile phone or a tablet computer.

[0083] Optionally, the notification message may be a Push message, which is a notification message that delivers information to a user in real time through a push service of a device.

[0084] In this example, the smart door lock can send a Push message to a mobile phone or tablet computer based on the WiFi function. After receiving the Push message sent by the smart door lock, the mobile phone or tablet computer can display the specific content of the Push message on the notification bar or lock screen interface, for example: There is someone in front of the door lock!

[0085] In step 203, after receiving a response message returned by the target screen device among the at least one screen device based on the notification message, the video acquired in real time by the camera of the smart door lock is sent to the target screen device.

[0086] As can be seen above, mobile phones and tablet computers can display the specific content of Push messages on the notification bar or lock screen interface.

[0087] When the user clicks on the notification message on the mobile phone, it means that the user is currently using the mobile phone. At this time, the mobile phone is the target screen device and can send a response message to the smart door lock. After receiving the response message sent by the mobile phone, the smart door lock only sends the video acquired through the camera to the mobile phone, without sending it to the tablet computer at the same time, thereby reducing network load and resource consumption.

[0088] Similarly, when the user clicks on the notification message on the tablet, the tablet is the target screen device and can send a response message to the smart door lock. After receiving the response message sent by the tablet, the smart door lock only sends the video acquired through the camera to the tablet without sending it to the mobile phone at the same time.

[0089] In step 204, after receiving the data packet containing the unlocking instruction sent by the target screen device based on the received video, the data packet is decrypted and / or decompressed to obtain the unlocking instruction.

[0090] Taking the target screen device as the aforementioned mobile phone as an example, after the smart door lock sends the acquired video to the mobile phone, the user can check the identity of the visitor in front of the door through the video on the mobile phone, and when deciding to open the smart door lock, send an unlocking command to the smart door lock through the mobile phone.

[0091] For example, while displaying the aforementioned video, the mobile phone may output an unlock inquiry prompt for asking the user whether to unlock the smart door lock, and provide two options of yes and no. When the user is sure to unlock the smart door lock, the user may click the option yes. When the mobile phone receives the user's selection message for the unlock inquiry prompt as yes, the data packet containing the unlock instruction may be encrypted and / or compressed. The data packet obtained after the encryption and / or compression operation is sent to the smart door lock.

[0092] After receiving the aforementioned data packet obtained through encryption and / or compression operation, the smart door lock can perform corresponding decryption and / or decompression operation on the data packet to obtain an unlocking instruction.

[0093] In step 205, the smart door lock is unlocked based on the unlocking instruction.

[0094] In the unlocking method of the smart door lock provided by the embodiment of the present disclosure, the smart door lock can turn on the WiFi function when it detects that the doorbell is pressed and / or detects that the target object stays in front of the smart door lock for a preset time, thereby avoiding unnecessary power consumption. Furthermore, in this embodiment, after turning on the WiFi function, the smart door lock can first send a notification message to at least one device with a screen, and after receiving a response message returned by the target device with a screen among at least one device with a screen based on the notification message, only send the video acquired by the camera to the target device with a screen. Compared with sending the video to each pre-set device with a screen, this method can reduce network load and resource consumption.

[0095] Figure 3FIG. 1 is a flowchart of another method for unlocking a smart door lock according to an exemplary embodiment of the present disclosure. The method can be executed by a target device with a screen, such as Figure 3 As shown, the exemplary embodiment method may include the following steps:

[0096] In step 301, the received video sent by the smart door lock is displayed on the screen of the target screen device.

[0097] The video includes a scene in front of the door where the smart door lock is installed.

[0098] In step 302, an unlocking inquiry prompt is output.

[0099] The unlock inquiry prompt is used to ask the user whether to unlock the smart door lock.

[0100] Optionally, the target device with a screen can display the received video on the screen and display a pop-up window to ask for unlocking. For example, a pop-up window can be displayed: Do you want to start smart door lock? and two options of yes and no can be given for the user to choose.

[0101] Alternatively, the target device with a screen can output the unlock inquiry prompt by voice while displaying the received video on the screen. For example, the voice output can be: Do you want to open the smart door lock? And two options of yes and no can be given on the screen for the user to choose. Alternatively, after the target device with a screen outputs the unlock inquiry prompt by voice, the microphone can be turned on to receive the user's response message to the unlock inquiry prompt output by voice.

[0102] Alternatively, the target screen device can display an unlock icon on the screen while displaying the received video.

[0103] In step 303, in response to the received user's selection message for the unlocking inquiry prompt to unlock the smart door lock, an unlocking instruction is sent to the smart door lock, so that the smart door lock opens the smart door lock based on the unlocking instruction.

[0104] When the user selects yes in response to the two options of yes and no, or when it is determined that the user's voice input received based on the microphone is yes, or after receiving the user's touch operation on the displayed unlock icon, the target screen device sends an unlock instruction to the smart door lock, so that the smart door lock opens the smart door lock based on the received unlock instruction.

[0105] In the unlocking method of the smart door lock provided by the embodiment of the present disclosure, after receiving the video sent by the smart door lock, the target screen device can display the video on the screen of the target screen device for the user to view. When the user checks the identity of the visitor in front of the door based on the video and determines to open the smart door lock, the target screen device can send an unlocking instruction to the smart door lock to achieve remote unlocking. In addition, since the unlocking instruction is sent after the user determines the identity of the visitor in front of the door, it is more secure.

[0106] Figure 4 FIG. 1 is a flowchart of another method for unlocking a smart door lock according to an exemplary embodiment of the present disclosure, and the method is also executed by the target device with a screen. Figure 4 As shown, the exemplary embodiment method may include the following steps:

[0107] In step 401, the received notification message sent by the smart door lock is displayed on the screen of the target screen device.

[0108] The notification message is used to indicate that a target object exists in front of the smart door lock.

[0109] As mentioned above, the notification message may be a Push message. After receiving the Push message sent by the smart door lock, the target device with a screen may display the specific content of the Push message on the notification bar or lock screen interface, for example, it may be: There is someone in front of the door lock!

[0110] In step 402, after detecting the user's touch operation on the notification message, a response message corresponding to the touch operation is sent to the smart door lock, so that the smart door lock sends the video acquired in real time by the camera of the smart door lock to the target screen device based on the response message.

[0111] When the user clicks on the above Push message, the target screen device can detect the user's touch operation on the Push message. At this time, the target screen device can send a response message to the smart door lock, so that the smart door lock can send the video acquired in real time by the camera of the smart door lock to the target screen device based on the received response message.

[0112] In step 403, the received video sent by the smart door lock is displayed on the screen of the target screen device.

[0113] The video includes a scene in front of the door where the smart door lock is installed.

[0114] In step 404, an unlocking inquiry prompt is output.

[0115] The unlock inquiry prompt is used to ask the user whether to unlock the smart door lock.

[0116] In step 405, in response to the user's selection message for the unlocking inquiry prompt being received to unlock the smart door lock, an encryption operation and / or compression operation is performed on the data packet containing the unlocking instruction.

[0117] In an optional example, the target screen-equipped device may place the unlocking instruction in a data packet and use a preset door lock key to encrypt and / or compress the data packet.

[0118] In another optional example, the target device with a screen may place the unlocking instruction, the current timestamp, and the identification information of the target device with a screen in one data packet, and perform encryption and / or compression operations on the data packet using a preset door lock key.

[0119] In step 406, the data packet obtained after the encryption operation and / or compression operation is sent to the smart door lock, so that the smart door lock opens the smart door lock based on the unlocking instruction contained in the data packet.

[0120] When the smart door lock determines that the data packet only contains the unlocking instruction after performing a decryption operation and / or a decompression operation on the received data packet using the preset door lock key, the smart door lock can start the smart door lock based on the unlocking instruction.

[0121] When the smart door lock determines after using the preset door lock key to decrypt and / or decompress the received data packet that the data packet contains unlocking instructions, timestamp, and identification information of the device with a screen, the smart door lock can perform further verification based on the timestamp and identification information of the device with a screen, thereby further improving security.

[0122] For example, for timestamps, the smart door lock can verify the time difference between the timestamp in the data packet and the current timestamp. When the time difference is within a certain time range, such as within 5 seconds, it is considered to have passed the verification. For the identification information of the device with a screen, the smart door lock can verify whether the device with a screen corresponding to the identification information of the device with a screen in the data packet is one of the at least one device with a screen pre-set by the user on the smart door lock. If so, it is considered to have passed the verification. At this point, the smart door lock can start the smart door lock based on the unlocking instruction in the data packet.

[0123] It should be noted that the present disclosure does not limit how the door lock key is synchronized to the target screen device.

[0124] In a possible implementation, the user can use the mobile phone to perform the first binding configuration on the smart door lock. During the binding configuration process, the mobile phone and the smart door lock can negotiate a door lock key based on the ECDH (Elliptic Curve Diffie-Hellmankey Exchange) algorithm and save it separately.

[0125] Then, the user can connect the mobile phone to other devices with screens respectively. After the connection, the mobile phone can authorize the negotiated door lock key to each device with screen respectively, so that the device with screen can obtain the door lock key.

[0126] In the unlocking method of the smart door lock provided by the embodiment of the present disclosure, when the user sends an unlocking instruction to the smart door lock through the target device with a screen, the target device with a screen can perform encryption and / or compression operations on the data packet containing the unlocking instruction based on the preset door lock key, and then send the encrypted and / or compressed data packet to the smart door lock.
