The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0039] It should be noted that the “plurality” mentioned in this article refers to two or more.

[0040] The implementation details of the technical solution of the embodiment of the present application are described in detail below:

[0041] In the first aspect of this embodiment, a door control linkage method based on express barcode is implemented. Figure 1 , Figure 1 1 is a flow chart of a pairing control method based on a smart door lock disclosed in an embodiment of the present invention. The method comprises:

[0042] S101, receiving a pairing request initiated by the first door lock, and the second door lock returns a pairing confirmation message to the first door lock; the first door lock enters a pairing confirmation state according to the pairing confirmation message; the pairing request includes the connection address of the first door lock; the pairing confirmation message includes the connection address of the second door lock; wherein, the first door lock and the second door lock are used to shoot the same scene.

[0043] Specifically, in this embodiment, the smart door lock starts smart pairing and forms a linkage door lock relationship through image analysis.

[0044] In this embodiment, the door lock 1 of resident 1 turns on the smart pairing function and periodically initiates a pairing request through communication technologies such as wifi, bluetooth, zigbee, etc. If other smart door locks (such as door lock 2) are in the smart pairing state, they return a pairing confirmation message to door lock 1. Then the state of door lock 2 changes to the smart pairing confirmation state, and records the connection address of the object to be confirmed (door lock 1).

[0045] Furthermore, after door lock 1 receives the pairing confirmation message returned by door lock 2, its own state also changes to the smart pairing confirmation state, and records the connection address of the object to be confirmed (door lock 2).

[0046] S102, comparing the first image and the second image captured by the first door lock and the second door lock, and determining that the first door lock and the second door lock are successfully paired according to the comparison result; if the pairing is successful, determining that the first door lock and the second door lock are interlocked door locks; the first image and the second image include timestamp information.

[0047] Further, comparing the first image and the second image collected by the first door lock and the second door lock, and determining that the first door lock and the second door lock are successfully paired according to the comparison result, includes:

[0048] comparing the timestamp information of the first image and the second image, and if the interval time is less than a first predetermined threshold, comparing the first image and the second image;

[0049] It is determined that the similarity between the person objects in the first image and the second image is greater than a second predetermined threshold; then it is determined that they are the same person, and it is determined that the first door lock and the second door lock are successfully paired.

[0050] Further, comparing the first image and the second image collected by the first door lock and the second door lock, and determining that the first door lock and the second door lock are successfully paired according to the comparison result, includes:

[0051] The first door lock sends the first image to the second door lock via the connection address of the second door lock, the second door lock performs a comparison based on the received first image and the second image captured by the second door lock, and sends a pairing success message to the first door lock according to the comparison result; or, the second door lock sends the second image to the first door lock via the connection address of the first door lock, the first door lock performs a comparison based on the received second image and the first image captured by the first door lock, and sends a pairing success message to the second door lock according to the comparison result.

[0052] Specifically, in this embodiment, when the camera of door lock 1 detects that there is activity in the corridor, such as people walking, a photo (first image) is taken and sent to the object to be confirmed through communication technologies such as wifi, bluetooth, zigbee, etc., with the timestamp of the photo being taken. Similarly, if door lock 2 also detects that there is activity in the corridor, the photo taken (second image) will also be sent to the object to be confirmed with a timestamp. If other door locks do not detect any activity, there is no need to send it.

[0053] The door lock receives the picture sent by the door lock to be confirmed, and determines whether it has sent the picture to be compared. If not, it takes the latest picture and sends it to the object to be confirmed. If it has been sent, the door lock compares the picture taken by itself with the picture sent by the door lock to be confirmed. First, compare the time interval of the timestamp. If the time interval is less than the threshold (for example, 1 minute), then compare the number of people in the photo, the type and color of clothes, the type and shape of the object, etc. to determine whether the photo is the same object. If there is still a situation that cannot be judged during the comparison process due to the problem of perspective, such as the large difference between the front and back of the person, the door lock and the two parties can negotiate again and take new photos and send them to the other party for comparison.

[0054] Door lock 1 compares the photos and finds the same people and items as door lock 2, then sends a pairing success message to the other party. Door lock 2 also sends a pairing success message to door lock 1. At this time, door lock 1 and door lock 2 will confirm each other as the linkage pairing object. If there is door lock 3, because the photos taken are inconsistent due to different floors, door lock 1 and door lock 3 will find large differences through photo comparison and cannot be paired, then send a configuration failure message to the other party and delete the recorded pairing object connection address to be confirmed.

[0055] S103, in response to the normal unlocking behavior of the first door lock or the second door lock, triggering linkage, sending a first control message to the linked door lock; the first control message includes canceling the recording.

[0056] Furthermore, in response to the normal unlocking behavior of the first door lock or the second door lock, the linkage is triggered and a first control message is sent to the linked door lock, including: when someone approaches the first door lock or the second door lock, the current person image is collected to determine whether it is a family member corresponding to the door lock; if so, it is determined to be a normal unlocking behavior, and a cancel recording control message is sent to the linked door lock; the linked door lock cancels the recording control according to the cancel recording control message, and deletes the recorded current person image file.

[0057] In some embodiments, the smart door lock can perform statistical analysis on the residents' unlocking behavior, establish unlocking behavior models for different household members, and determine the unlocking behavior that meets the behavior model as privacy protection behavior, and send it to the paired linked door lock to inform the cancellation of the recording activity.

[0058] Specifically, the door lock 1 collects images of people who open the door lock by using fixed keys, fingerprints, etc., and records the time when each person opens the door lock. For example, the time when person 1 opens the door lock is 8 am and 8 pm on weekdays, and the time when person 2 opens the door lock is 7 am and 4 pm every day. The door lock 1 establishes a normal unlocking behavior model for each family member.

[0059] In some embodiments, when door lock 1 detects that a person is approaching the door lock, it first collects an image of the person to determine whether it is a family member. If so, it then determines whether it is a normal unlocking time. If so, it is considered a normal unlocking behavior. Door lock 1 informs the paired linkage door lock: door lock 2 to cancel the recording activity. If the door lock detects that the person is not a family member, or the family member is not active during the normal unlocking time, the normal process is followed and the linkage is not triggered. The reason for using portrait + time for simultaneous judgment instead of relying solely on portrait recognition is mainly due to the problem of lighting in the corridor, which may cause incorrect portrait recognition to avoid being deliberately imitated and circumvented.

[0060] In some embodiments, after the door lock 2 receives a message from the paired linked door lock informing of the cancellation of the recording activity, the door lock 2 stops the recording function activated due to the detection of human activity and deletes the recorded files.

[0061] In some embodiments, when the door lock 1 detects the presence of family members and other strangers at the same time, it can choose to trigger the linkage or not according to the configuration; the default recommendation is not to trigger the linkage.

[0062] In summary, in this embodiment, by receiving a pairing request initiated by the first door lock, the second door lock returns a pairing confirmation message to the first door lock; the first door lock enters a pairing confirmation state according to the pairing confirmation message; the pairing request includes the connection address of the first door lock; the pairing confirmation message includes the connection address of the second door lock; wherein the first door lock and the second door lock are used to shoot the same scene; the first image and the second image collected by the first door lock and the second door lock are compared, and the first door lock and the second door lock are determined to be paired successfully according to the comparison result; if the pairing is successful, it is determined that the first door lock and the second door lock are mutually linked door locks; the first image and the second image include timestamp information; in response to the normal unlocking behavior of the first door lock or the second door lock, the linkage is triggered, and the first control message is sent to the linked door lock; the first control message includes canceling the recording. Compared with the prior art, the embodiment of the present application has the following beneficial effects: a linkage pairing object is established through intelligent pairing detection of the door lock, and the linkage object is informed to turn off the recording for normal unlocking activities, which effectively protects personal privacy and also reduces the consumption of recording for the door lock.
