[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0033] The distributed modeling system and method provided in the embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0034] Figure 1 An unlocking method applied to a client provided by an embodiment of the present invention is shown, and the unlocking method includes:

[0035] Step 101: Send a key request to the smart lock.

[0036] The smart lock is communicatively connected to the camera, and the camera is integrated on the smart lock, is independent of the smart lock, and is located in the same physical space as the smart lock.

[0037] Specifically, a smart lock refers to an electronic lock that can be unlocked through biometrics and can communicate with other network devices through the network.

[0038] The camera can be integrated into the smart lock, or the camera is independent of the smart lock and is located in the same physical space as the smart lock, so that the camera can capture image data within a certain range of the smart lock. In addition, the camera is connected to the smart lock in communication, so that the camera can transmit the captured image data to the smart lock, so that the smart lock can transmit the image data to other network devices connected in communication, such as clients, servers, etc., so that the user can view the image in front of the smart lock in real time through the image data captured by the camera, ensuring the safety of the user's unlocking operation.

[0039] The key request is used to indicate obtaining an unlocking key for unlocking the smart lock. In addition, the key request can be sent to the smart lock through a process such as device direct connection, peer to peer (p2p), and streaming media forwarding.

[0040] Of course, when the client sends a key request to the smart lock, the key request can carry the terminal information corresponding to the client, so that the smart lock can verify through the terminal information whether the terminal corresponding to the client is the terminal pre-bound to the smart lock. If so, the next step can be performed. If not, the unlocking process is terminated to improve the security of unlocking.

[0041] Step 102: Receive the unlocking key sent by the smart lock based on the key request.

[0042] The unlocking key includes image data captured by the camera within a preset time period, which enables the client to display the image corresponding to the image data. Since the camera is integrated in the smart lock, it is independent of the smart lock and is located in the same physical space as the smart lock, that is, the image data captured by the camera is the image within a certain range of the smart lock, which realizes the real-time nature of the unlocking key. This enables the user to see the picture scene of the unlocking during the entire unlocking process through the image data.

[0043] Specifically, the preset time period can be within the first N seconds of the current time, and the value of N can be set according to actual conditions, for example, it can be 1s or 2s, etc., which means that the unlocking key is not fixed, but changes in real time with time. Of course, the smaller the value of N, the higher the real-time performance of the unlocking key.

[0044] In this way, when the smart lock executes the unlock signaling, an unlock key is required. In the related art, the unlock key is generally set by the user and includes fingerprint information, face information, 6-digit key, etc. These unlock keys are set and fixed by the user, which makes them easy to lose or simulate, and the security is low. In this embodiment, the unlock key includes the image data captured by the camera within a preset time period, so that the unlock key is generated by the smart lock, and the image in front of the smart lock is the unlock key, which is real-time and non-fixed, so that the unlock key is not easy to be simulated and will not be lost, ensuring the security of the unlock key; in addition, since the unlock key is generated by the smart lock, it does not need to be set by the user, omitting the user's key setting process, and avoiding the user from remembering the key set by himself, simplifying the user's unlocking operation and providing convenience for the user to unlock.

[0045] In addition, specifically, the unlocking key may also include an authentication identifier (token) to further improve the security of the unlocking key.

[0046] Step 103: In response to the unlocking operation input by the user, an unlocking signaling is sent to the smart lock.

[0047] Specifically, after obtaining the unlocking key, if the client receives an unlocking operation input by the user, it can send an unlocking signaling to the smart lock in response to the unlocking operation input by the user.

[0048] The unlock signaling includes the unlock key and the terminal information corresponding to the client. The terminal information is used by the smart lock to verify whether the terminal corresponding to the client is the terminal pre-bound to the smart lock.

[0049] The process of binding a terminal to a smart lock is the process of storing the terminal information of the terminal in the security verification device list of the smart lock. The security verification device list can be a terminal list maintained by the smart lock. The terminal information in the terminal list is the terminal information of the terminal that has been bound to the smart lock.

[0050] Specifically, the terminal information can be the terminal's mobile phone number, user identification information, etc., and of course, it can also be a string consisting of the terminal's hardware feature code and user identification information. For example, the hardware feature code can be a 32-bit universally unique identifier (uuid) generated by the client, and the length of the string consisting of the hardware feature code and user identification information can be no more than 64 bits, ensuring that the terminal information is unique and non-repetitive.

[0051] Step 104: receiving the first response information sent by the smart lock after unlocking based on the unlocking key and the terminal information and successfully unlocking.

[0052] The first response information is used to indicate that the smart lock is unlocked successfully.

[0053] Among them, the smart lock is unlocked based on the unlocking key and the terminal information. In this process, the smart lock can verify whether the terminal corresponding to the client is the terminal bound to the smart lock through the terminal information and the terminal binding code of the terminal pre-stored in the smart lock. If it is determined that the terminal corresponding to the client is the terminal bound to the smart lock, it verifies whether the unlocking key is correct. If it is determined that the unlocking key is correct, it performs the unlocking operation and sends the first response information indicating the successful unlocking to the client after the unlocking is successful. At this time, the user can determine the unlocking result through the first response information received by the client.

[0054] In this way, the client in this embodiment sends a key request to the smart lock, and the smart lock is communicatively connected with the camera. The camera is integrated on the smart lock or independent of the smart lock and is located in the same physical space as the smart lock, and the key request is used to indicate the acquisition of an unlocking key for unlocking the smart lock; the unlocking key sent by the smart lock based on the key request is received, wherein the unlocking key includes image data captured by the camera within a preset time period; an unlocking signaling is sent to the smart lock in response to an unlocking operation input by the user, wherein the unlocking signaling includes the unlocking key and the terminal information corresponding to the client; and the first response information sent by the smart lock after unlocking based on the unlocking key and the terminal information and successful unlocking is received, and the first response information is used to indicate that the smart lock is successfully unlocked. The unlocking key is generated by the smart lock, and the picture in front of the smart lock is the unlocking key, which is real-time and non-fixed, so that the unlocking key is not easily simulated or lost, thereby ensuring the security of the unlocking key and does not require visitors to input the unlocking key, thereby simplifying the visitor's unlocking process; in addition, since the unlocking key is generated by the smart lock, it does not need to be set by the user, omitting the user's key setting process and avoiding the user from remembering the key set by himself, thereby simplifying the user's unlocking operation and providing convenience for the user to unlock.

[0055] In one implementation, before sending a key request to the smart lock, the client may also receive identity information input by the user; after verifying that the user is a legitimate user through the identity information, the step of sending a key request to the smart lock is entered.

[0056] The user's identity information can be biometric information such as the user's fingerprint, face, etc., or can be information such as a password pre-set by the user. By verifying whether the user is a legitimate user, it is ensured that the user initiates the unlocking operation under his own authorization, preventing others from remotely unlocking the door when the terminal corresponding to the client is lost, thereby ensuring the security of unlocking.

[0057] In addition, in one implementation, after receiving the smart lock to unlock based on the unlocking key and the terminal information, it also includes:

[0058] Receiving a second response message sent after the smart lock fails to unlock, wherein the second response message is used to indicate that the reason for the failure to unlock the smart lock is that the terminal corresponding to the client is not bound to the smart lock;

[0059] Based on the second response information, sending a binding signaling to the smart lock through the server, wherein the binding signaling includes the terminal information corresponding to the client and is used to instruct the smart lock to perform a binding operation between the terminal and the smart lock;

[0060] Receive a third response message sent by the smart lock through the server, where the third response message is used to indicate that the smart lock is successfully bound based on the binding signaling.

[0061] Specifically, the smart lock needs to be bound to the terminal before a valid key can be generated. If the smart lock fails to unlock based on the unlocking key and the terminal information, the reason for the unlocking failure can be determined, which may be that the terminal corresponding to the client is not bound to the smart lock, or that the unlocking key is abnormal.

[0062] If the reason for the failure of the smart lock to unlock is that the unlocking key is abnormal, the smart lock can send a key abnormality message to the client. At this time, the client can resend a key request to the smart lock based on the key abnormality message.

[0063] If the reason why the smart lock fails to unlock is that the terminal corresponding to the client is not bound to the smart lock, the smart lock can send a second response message to the client indicating that the reason why the smart lock fails to unlock is that the terminal corresponding to the client is not bound to the smart lock; at this time, the client can send a binding signaling to the server based on the second response message, and then the server sends the binding signaling to the smart lock, the binding signaling includes the terminal information corresponding to the client, and is used to instruct the smart lock to perform the binding operation of the terminal and the smart lock; then the smart lock performs the binding operation of the terminal and the smart lock, that is, stores the terminal information in the terminal list corresponding to the smart lock, and after the binding is successful, sends a third response message to the server indicating that the smart lock is successfully bound. At this time, the server sends the third response message to the client and stores the updated terminal list of the smart lock, which includes the terminal binding codes of the terminals that have been bound to the smart lock; after the client receives the third response message, the user can re-send the unlocking signaling to the smart lock to continue the unlocking operation.

[0064] In this way, after the unlocking fails, the binding process between the client and the smart lock enables the unlocking operation to continue through the client.

[0065] In addition, in one implementation, sending an unlock signaling to the smart lock includes:

[0066] An unlocking request is sent to a server, and the server verifies, based on the unlocking request, that the terminal corresponding to the client is the terminal bound to the smart lock, and sends the unlocking signaling to the smart lock; wherein the server synchronizes a terminal list corresponding to the smart lock, the terminal list includes the terminal binding code of the terminal bound to the smart lock, the unlocking request includes the unlocking key, the terminal information of the client and the device information of the smart lock, the terminal information of the client and the terminal list are used to verify whether the client is the terminal bound to the smart lock, and the device information of the smart lock is used to determine the communication address of the smart lock.

[0067] Specifically, when the client sends an unlock signaling to the smart lock, it can first send an unlock request to the server, which includes the unlock key, the terminal information of the client, and the device information of the smart lock, and the server synchronizes the terminal list corresponding to the smart lock, and the terminal list includes the terminal binding code of the terminal bound to the smart lock; at this time, the server can judge whether there is a terminal binding code consistent with the terminal information corresponding to the client in the terminal binding code of the terminal bound to the smart lock based on the terminal list. If there is, it means that the terminal bound to the smart lock contains the terminal corresponding to the client, and then the unlock signaling can be sent to the smart lock based on the device information of the smart lock. In this way, the server realizes the verification process of the terminal corresponding to the client, and further ensures the security of unlocking.

[0068] Optionally, after the client sends an unlock request to the server, the following steps may also be included:

[0069] receiving indication information sent by the server, the indication information being used to indicate that the number of terminal binding codes stored in the terminal list has reached a preset value;

[0070] Sending a deletion instruction to the smart lock through the server based on the indication information, wherein the deletion instruction is used to instruct the smart lock to delete at least one of the terminal binding codes stored in the terminal list;

[0071] Receive a fourth response message sent by the smart lock through the server, wherein the fourth response message is used to indicate that at least one terminal binding code is deleted successfully, wherein the server and the smart lock synchronize an updated terminal list.

[0072] Specifically, if the server determines based on the terminal list that there is no terminal binding code consistent with the terminal information corresponding to the client in the terminal binding code of the terminal bound to the smart lock, that is, the terminal corresponding to the client is not included in the terminal list, and the number of terminal binding codes included in the terminal list has reached a preset value, then an indication information for indicating that the number of terminal binding codes stored in the terminal list has reached a preset value can be sent to the client; at this time, the client can send a deletion instruction for instructing the smart lock to delete at least one of the terminal binding codes stored in the terminal list based on the indication information to the server, and the server forwards the deletion instruction to the smart lock; after receiving the deletion instruction, the smart lock can delete at least one of the terminal binding codes stored in the terminal list. Specifically, the smart lock can perform the deletion operation according to the binding time sequence of the terminal binding code and the time sorting from far to near, and after the deletion is successful, send a fourth response information to the server for indicating that the at least one terminal binding code is successfully deleted; the server can forward the fourth response information to the client, and synchronize the terminal list updated by the smart lock itself; after receiving the fourth response information, the client can send a binding signaling to the smart lock through the server to perform the binding process between the terminal corresponding to the client and the smart lock, thereby ensuring the smooth unlocking process of the smart lock.

[0073] In this way, the above embodiment realizes that the unlocking key is generated by the smart lock, and the picture in front of the smart lock is the unlocking key, which is real-time and non-fixed, so that the unlocking key is not easy to be simulated or lost, thereby ensuring the security of the unlocking key; in addition, since the unlocking key is generated by the smart lock, it does not need to be set by the user, the user's key setting process is omitted, and the user is prevented from remembering the key set by himself, which simplifies the user's unlocking operation and provides convenience for the user to unlock.

[0074] like Figure 2 As shown in the figure, it is a flowchart of the steps of the unlocking method applied to the smart lock in the embodiment of the present application, and the method includes the following steps:

[0075] Step 201: Receive a key request sent by a client.

[0076] The smart lock receives a key request sent by the client, wherein the key request is used to instruct to obtain an unlocking key for unlocking the smart lock.

[0077] The smart lock is communicatively connected to a camera, and the camera is integrated on the smart lock or is independent of the smart lock and is located in the same physical space as the smart lock.

[0078] Step 202: Send the unlocking key to the client based on the key request.

[0079] The unlocking key includes image data captured by the camera within a preset time period.

[0080] It should be noted that the specific content of the unlocking key can be found in the relevant content of the client-side embodiment, which will not be repeated here.

[0081] Step 203: receiving an unlocking signaling sent by the client in response to an unlocking operation input by the user.

[0082] In this step, the smart lock receives the unlocking signaling sent by the client, wherein the unlocking signaling includes the unlocking key and the terminal information corresponding to the client.

[0083] It should be noted that the specific content of the unlocking signaling can be found in the relevant content of the client side embodiment, which will not be described in detail here.

[0084] Step 204: Unlock the device based on the unlocking key and the terminal information, and send a first response message to the client after the unlocking is successful.

[0085] The first response information is used to indicate that the smart lock is unlocked successfully.

[0086] The smart lock can be unlocked based on the unlocking key and the terminal information, and after the unlocking is successful, it sends a first response message to the client, where the first response message is used to indicate that the smart lock is unlocked successfully.

[0087] In this way, this embodiment receives a key request sent by the client, the smart lock is communicatively connected with the camera, the camera is integrated on the smart lock or independent of the smart lock and is located in the same physical space as the smart lock, and the key request is used to indicate the acquisition of an unlocking key for unlocking the smart lock; based on the key request, the unlocking key is sent to the client, wherein the unlocking key includes image data captured by the camera within a preset time period; the unlocking signaling sent by the client is received, and the unlocking signaling includes the unlocking key and the terminal information corresponding to the client; the lock is unlocked based on the unlocking key and the terminal information, and a first response message is sent to the client after the unlocking is successful, and the first response message is used to indicate that the smart lock is successfully unlocked. The unlocking key is generated by the smart lock, is real-time and non-fixed, and the picture in front of the smart lock is the unlocking key, so that the user can see the live scene in front of the smart lock during the whole unlocking process, so that the unlocking key is not easy to be simulated and will not be lost, thereby ensuring the security of the unlocking key, and does not require visitors to obtain the key to unlock, simplifying the visitor's unlocking process; in addition, since the unlocking key is generated by the smart lock, it does not need to be set by the user, omitting the user's key setting process and avoiding the user from remembering the key set by himself, simplifying the user's unlocking operation and providing convenience for the user to unlock.

[0088] In one implementation, the unlocking based on the unlocking key and the terminal information includes:

[0089] Based on the terminal information and the terminal binding code of the terminal pre-stored in the smart lock and pre-bound to the smart lock, verify whether the terminal corresponding to the client is the terminal bound to the smart lock;

[0090] If it is determined that the terminal corresponding to the client is the terminal bound to the smart lock, verify whether the unlocking key is correct;

[0091] If it is determined that the unlocking key is correct, an unlocking operation is performed and it is determined that the unlocking is successful.

[0092] Specifically, the smart lock is pre-set with a terminal list, which includes the terminal binding codes of the terminals that are pre-bound to the smart lock. When the smart lock verifies whether the terminal corresponding to the client is the terminal bound to the smart lock, it can determine whether there is a terminal binding code consistent with the terminal information corresponding to the client in the terminal binding code of the terminal bound to the smart lock. If so, it is determined that the terminal corresponding to the client is the terminal bound to the smart lock. Then, if it is determined that the unlocking key is correct, the lock is unlocked and unlocked successfully.

[0093] In this way, the unlocking process is verified by the terminal information and the unlocking key, which prevents the terminal that is not bound to the smart lock from successfully unlocking the lock remotely when the unlocking key is obtained, thereby ensuring the security of unlocking.

[0094] In one implementation, after unlocking based on the unlocking key and the terminal information, the following steps are further included:

[0095] If the unlocking fails, a second response message is sent to the client, wherein the second response message is used to indicate that the reason why the smart lock fails to unlock is that the terminal corresponding to the client is not bound to the smart lock;

[0096] Receiving a binding signaling sent by the server, wherein the binding signaling is sent by the client based on the second response information, and the binding signaling includes terminal information corresponding to the client, and is used to instruct the smart lock to perform a binding operation between the terminal and the smart lock;

[0097] The binding operation between the terminal and the smart lock is performed based on the binding signaling, and after the binding is successful, a third response message is sent to the client through the server, and the third response message is used to indicate that the smart lock is successfully bound.

[0098] Specifically, if the reason why the smart lock fails to unlock is that the terminal corresponding to the client is not bound to the smart lock, the smart lock can send a second response message to the client indicating that the reason why the smart lock fails to unlock is that the terminal corresponding to the client is not bound to the smart lock; at this time, the client can send a binding signaling to the server based on the second response message, and then the server sends the binding signaling to the smart lock, the binding signaling includes the terminal information of the client, and is used to instruct the smart lock to perform the binding operation of the terminal and the smart lock; then the smart lock performs the binding operation of the terminal and the smart lock, that is, stores the terminal information as a terminal binding code in the terminal list corresponding to the smart lock, and after the binding is successful, sends a third response message to the server indicating that the smart lock is successfully bound. At this time, the server sends the third response message to the client and stores the updated terminal list of the smart lock, which includes the terminal binding codes of the terminals that have been bound to the smart lock; after the client receives the third response message, the user can re-send the unlocking signaling to the smart lock to continue the unlocking operation.

[0099] In one implementation, the receiving the unlocking signaling sent by the client in response to the unlocking operation input by the user includes:

[0100] Receive an unlocking signaling sent by the client through a server, wherein the unlocking signaling is sent when the server receives an unlocking request sent by the client and verifies based on the unlocking request that the terminal corresponding to the client is the terminal bound to the smart lock; wherein the server synchronizes a terminal list corresponding to the smart lock, the terminal list includes terminal binding codes of terminals bound to the smart lock, the unlocking request includes the unlocking key, the terminal information corresponding to the client and the device information of the smart lock, the terminal information of the client and the terminal list are used to verify whether the terminal corresponding to the client is the terminal bound to the smart lock, and the device information of the smart lock is used to determine the communication address of the smart lock.

[0101] It should be noted that the process can refer to the relevant content of the client-side embodiment, and will not be described in detail here.

[0102] In one implementation, before receiving the unlocking signaling sent by the client through the server, the method further includes:

[0103] receiving a deletion instruction sent by the client through the server, the deletion instruction being used to instruct the smart lock to delete at least one of the terminal binding codes stored in the terminal list, and the deletion instruction being sent after the client receives the indication information sent by the server, the indication information being used to indicate that the number of terminal binding codes of the terminals stored in the terminal list has reached a preset value;

[0104] deleting at least one of the terminal binding codes stored in the terminal list based on the deletion instruction, and synchronizing the updated terminal list to the server;

[0105] The server sends fourth response information to the client, where the fourth response information is used to indicate that at least one terminal binding code is successfully deleted.

[0106] It should be noted that the process can refer to the relevant content of the client-side embodiment, and will not be described in detail here.

[0107] Below through Figure 3 A specific embodiment of the present application is described. Specifically, the embodiment includes the following steps:

[0108] Step 1: The client sends a key request to the smart lock.

[0109] The client can be an application APP corresponding to the smart lock, which is used to unlock the smart lock. Of course, the client can also be a terminal with the application installed. Here, the client is taken as an APP corresponding to the smart lock as an example.

[0110] The smart lock is communicatively connected to the camera, and the camera is integrated on the smart lock or independent of the smart lock and located in the same physical space as the smart lock, so that the camera can capture image data within a certain range of the smart lock and transmit the captured image data to the smart lock.

[0111] In this step, the key request can be a stream acquisition request (i.e., a request for acquiring a video stream). The stream acquisition method may include device direct connection, p2p, streaming media forwarding, etc. Of course, the key request may also carry the terminal information corresponding to the client, so that the smart lock can verify whether the terminal corresponding to the client is the terminal pre-bound by the smart lock through the terminal information.

[0112] Step 2: The smart lock sends the unlocking key to the client.

[0113] Specifically, if the smart lock supports remote unlocking, the unlocking key can be sent to the smart lock. At this time, the camera transmits the image data captured within a preset time period to the smart lock, such as the video frame data of the first N seconds of the current time, and the smart lock uses the image data as the unlocking key and sends the unlocking key to the client.

[0114] Of course, the unlocking key may also include an unlocking token, etc.

[0115] In addition, the key request can also carry the terminal information corresponding to the client. Specifically, the smart lock needs to be bound to the terminal to generate a valid key, so the smart lock can determine whether there is a valid remote unlocking operation based on the terminal information carried in the key request. If it is confirmed that there is, the unlocking key can be sent. If it is confirmed that there is no unlocking key, it will not be sent.

[0116] Step 3: The client's local system verifies the user's legitimacy.

[0117] During this process, the client can receive the identity information entered by the user and verify the legitimacy of the user through the identity information.

[0118] Identity information may include biometric features such as fingerprints and faces, and may also include set passwords.

[0119] This step is to ensure that the user only initiates the unlocking operation under his own authorization, to prevent the lock from being remotely unlocked by others when the client is lost.

[0120] Step 4: After the client passes the verification, it sends an unlock request to the server. The unlock request includes the terminal information corresponding to the client, the unlocking key, and the device information of the smart lock.

[0121] Step 5: The server makes a terminal binding determination.

[0122] In this process, the server synchronizes a terminal list corresponding to the smart lock, and the terminal list includes the terminal binding codes of the terminals bound to the smart lock, and the terminal binding codes correspond to the terminals one by one. Based on the terminal list, the server determines whether there is a terminal binding code consistent with the terminal information corresponding to the client among the terminal binding codes of the terminals bound to the smart lock; if there is, it means that the terminals bound to the smart lock include the terminal corresponding to the client, and then proceed to step 6; if there is no terminal binding code and the number of terminal binding codes included in the terminal list has reached the preset value, then proceed to step 14.

[0123] Step 6: The server sends an unlock signaling to the smart lock, which includes an unlock key and the terminal information corresponding to the client.

[0124] Step 7: The smart lock detects whether the unlocking process is legal.

[0125] During this process, the smart lock can verify whether the terminal corresponding to the client is the terminal bound to the smart lock through the terminal information and the terminal binding code of the terminal pre-bound to the smart lock stored in the smart lock. If it is determined that the terminal corresponding to the client is the terminal bound to the smart lock, it verifies whether the unlocking key is correct. If it is determined that the unlocking key is correct, it determines that the unlocking process is legal, and then performs the unlocking operation.

[0126] Step 8: After the smart lock determines that the unlocking process is legal and performs the unlocking operation, it sends a response message of successful unlocking to the client.

[0127] Step 9: If the smart lock fails to unlock, and the reason for the unlocking failure is that the terminal corresponding to the client is not bound to the smart lock, a response message indicating that the unlocking failed and the terminal is not bound is sent to the client.

[0128] Of course, if the reason for the unlocking failure is that the unlocking key is abnormal, you can re-enter step 3, that is, restart the unlocking process.

[0129] Step 10: The client sends a binding signaling to the server, where the binding signaling includes terminal information corresponding to the client.

[0130] Step 11: The server forwards the binding signaling to the smart lock.

[0131] Step 12: After the terminal is successfully bound, the smart lock refreshes the terminal list, synchronizes the updated terminal list with the server, and sends a response message indicating successful binding to the server.

[0132] Step 13: The server updates the terminal list and sends a response message indicating successful binding to the client.

[0133] Step 14: The server sends an indication message to the client indicating that the number of terminal binding codes has reached a preset value, that is, the terminal list is full.

[0134] Step 15: The client sends a deletion instruction to the server to instruct the deletion of the terminal binding code.

[0135] Step 16: The server forwards the deletion instruction to the smart lock.

[0136] Step 17: After the smart lock successfully deletes the bound terminal, it refreshes the terminal list, synchronizes the updated terminal list with the server, and sends a response message indicating successful deletion to the server;

[0137] Step 18: The server forwards a response message indicating successful deletion to the client.

[0138] Through the above process, the entire process of client remote unlocking is realized.

[0139] In this way, the above embodiment allows the entire unlocking process to be fully visible, and does not require the visitor to input an unlocking key, which simplifies the visitor's unlocking process while ensuring the user's real-time security.
