[0038] 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.

[0039] Existing remote unlocking methods usually require a network connection. If the network connection is unstable or interrupted, the remote unlocking will fail. Therefore, the existing remote unlocking methods usually require manual operation by the user, which increases the complexity of the operation and the possibility of error, thereby affecting the remote unlocking safety, operability, and real-time performance of the smart door lock. Therefore, a remote unlocking system for a smart door lock is needed, which can be safe, easy to operate, and respond to unlocking instructions in a timely manner to unlock the door.

[0040] The remote unlocking method of the smart door lock described in the preferred embodiment of the present invention is as follows: Figure 1 As shown, the remote unlocking method of the smart door lock includes the following steps:

[0041] Step S10: When it is detected that the doorbell button of the smart door lock is triggered, a video call request is initiated to the homeowner terminal. When the video call request is successfully connected, an encrypted unlocking instruction generated by the server is received.

[0042] Specifically, when it is detected that the doorbell button of the smart door lock is triggered, a video call request is sent to the homeowner's terminal (the visitor initiates a video call request through the doorbell on the smart door lock and establishes a video call link with the homeowner's APP. At this time, the door lock and the server start timing and record the time when the video call is established); when the video call request is successfully connected, the smart door lock establishes a video call connection with the homeowner's terminal and receives the encrypted unlocking instruction sent by the server; wherein the encrypted unlocking instruction is generated by the server by encrypting the serial number of the smart door lock and the ciphertext sent by the homeowner's terminal according to the key, and the ciphertext includes: timestamp and unlocking instruction The householder terminal (APP) uses the public key to encrypt the device ESN, the current timestamp plus three minutes and the unlocking instruction and sends them to the server. The server uses the private key to decrypt and verify whether it is valid. If it is valid, the server uses randomCode as the key to perform AES encryption on the current timestamp plus three minutes + unlocking instruction in the ciphertext to generate an encrypted instruction and send it to the smart door lock. The validity period of the key is set to 3 minutes to ensure the security and uniqueness of the instruction; wherein, the randomCode includes the device code (ESN) and the function set. The function set is different for each lock and can be replaced by others.

[0043] Step S20: decrypt the encrypted unlocking instruction according to a preset decryption algorithm to generate a decryption result. If the decryption result is successful, detect whether the visitor presses a confirmation button within a preset time.

[0044] Specifically, the encrypted unlocking instruction is decrypted according to the preset key to generate a decrypted timestamp; it is determined whether the decrypted timestamp does not exceed the first preset time; if the decrypted timestamp does not exceed the first preset time, it is detected whether the visitor presses the confirmation button within the second preset time. After the door lock receives the encrypted unlocking instruction, it uses randomCode to decrypt. At this time, the lock end determines whether the decrypted timestamp is valid. If the decryption is successful and valid, the door lock will be in a ready to unlock state, waiting for the visitor to press the confirmation button (# key) to confirm within 3 minutes.

[0045] Furthermore, if the decrypted timestamp does not exceed the first preset time, the smart door lock is marked as ready to unlock. If it is detected that the visitor does not press the confirmation button within the second preset time, the ready to unlock state of the smart door lock is restored to the initial state (after the visitor communicates with the homeowner in the video call to confirm the unlocking requirement, he confirms the unlocking by pressing the # key. After the door lock receives the visitor's confirmation command, it starts timing and waits for the unlocking to be completed within 3 minutes. If the visitor does not press the # key to confirm the unlocking within 3 minutes, or the door lock's timer exceeds 3 minutes, the door lock will cancel the ready to unlock state, restore the initial state, and wait for the next unlocking request).

[0046] Step S30: If the visitor presses the confirmation button within the preset time, the unlocking operation is performed.

[0047] Specifically, if the visitor presses the confirmation button within the preset time, a confirmation instruction is generated; the unlocking operation is performed according to the confirmation instruction. (If the visitor successfully presses the # key to confirm the unlocking within 3 minutes, the door lock will perform the unlocking operation and open the door lock).

[0048] As an example, Figure 2 As shown, the device and APP establish a video channel. If the APP does not click on one-key unlocking at this time, no operation will be performed. If the APP clicks on one-key unlocking, the APP first obtains the encrypted public key from the cloud server to encrypt and send the device ESN + current timestamp plus three minutes + unlocking instruction to the cloud server. The server receives the instruction and decrypts it with the private key. If it is valid, the randomCode above is used as the key to encrypt the timestamp + unlocking instruction parsed from the ciphertext. After encryption, the encrypted instruction is generated and sent to the smart door lock. The smart door lock uses randomCode to decrypt the encrypted instruction to check whether it can be decrypted and whether the instruction is still valid. If it is valid, it enters the unlocking ready state and waits for the visitor to press # to confirm the unlocking. If the confirmation button is not pressed or the timeout occurs, it is canceled. If the confirmation button is pressed and it does not expire, the door opening action is completed.

[0049] Beneficial effects of the present invention:

[0050] (1) The present invention verifies the visitor's identity through video calls, ensuring that only visitors confirmed by the homeowner can obtain temporary unlocking authority.

[0051] (2) The temporary key of the present invention is valid for only 3 minutes, which effectively prevents the key from being abused.

[0052] (3) The present invention generates keys by adopting an asymmetric encryption algorithm to ensure the security of key transmission.

[0053] (4) The present invention generates keys by adopting an asymmetric encryption algorithm to ensure the security of key transmission.

[0054] Furthermore, if Figure 3 As shown, based on the remote unlocking method of the above-mentioned smart door lock, the present invention also provides a remote unlocking system of a smart door lock, wherein the remote unlocking system of the smart door lock includes:

[0055] The instruction acquisition module 51 is used to initiate a video call request to the homeowner terminal when it is detected that the doorbell key of the smart door lock is triggered, and when the video call request is successfully connected, receive the encrypted unlocking instruction generated by the server;

[0056] The unlocking instruction decryption module 52 is used to decrypt the encrypted unlocking instruction according to a preset key to generate a decryption result. If the decryption result is successful, it detects whether the visitor presses a confirmation button within a preset time;
