[0044] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0045] In the following introduction, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The following introduction provides multiple embodiments of the present application. Different embodiments can be replaced or combined, so the present application can also be considered to include all possible combinations of the same and / or different embodiments described. Therefore, if one embodiment includes features A, B, and C, and another embodiment includes features B and D, then the present application should also be considered to include embodiments containing one or more of all other possible combinations of A, B, C, and D, even though the embodiment may not be clearly described in the following text.

[0046] The following description provides examples and does not limit the scope, applicability, or examples set forth in the claims. Changes may be made to the function and arrangement of the elements described without departing from the scope of the present application. Various examples may appropriately omit, replace, or add various processes or components. For example, the described method may be performed in an order different from the order described, and various steps may be added, omitted, or combined. In addition, features described in some examples may be combined in other examples.

[0047] Smart door locks are primarily used to improve security and ease of use. With the rapid development of technology, smart door lock technology is constantly improving, making it increasingly common in people's daily lives. However, when using smart door locks, some security issues are inevitable. For example, unauthorized users can deduce the unlocking password through trial and error, forge fingerprints, or forge facial features through impersonation or makeup techniques to undermine the protection mechanism of smart door locks. Therefore, it is necessary to improve the locking security of smart door locks when in use.

[0048] The present application provides a locking method for a smart door lock, which obtains control information of the smart door lock and a set locking time, then generates a password based on this information, and sends the password to the smart door lock. The smart door lock locks the smart door lock within the set locking time according to the password. When the user unlocks the smart door lock, it is necessary to power the unlocking control module in the smart door lock to end or release the lock within the first locking time, and then the smart door lock can be unlocked by the unlocking password preset by the unlocking control module of the smart door lock, which increases the complexity of unlocking the smart door lock and prevents illegal users from destroying the protection mechanism of the smart door lock through multiple trial and error or imitating biometric information, thereby improving the security of the smart door lock.

[0049] For example, the locking method of a smart door lock shown in the embodiments of the present application can be applied to a terminal device or a smart door lock. The terminal device may include a smart interactive tablet, mobile phone, tablet computer, laptop computer, desktop computer, all-in-one computer, in-vehicle multimedia, server, or workstation.

[0050] The following will be combined Figures 1 to 17 , the locking method of the smart door lock provided in the embodiment of the present application is introduced in detail.

[0051] See Figure 1 and Figure 2 , provides a schematic diagram of the architecture of a locking system for a smart door lock according to an embodiment of the present application. The system includes a terminal device and a smart door lock. When a user needs to lock the smart door lock, he inputs the first control information of the smart door lock and sets the first locking time in the terminal device. The terminal device generates a first password based on this information using a preset algorithm. Figure 1 As shown, when the smart door lock is connected to the network, the terminal device sends the generated first password directly to the smart door lock, such as Figure 2 As shown, when the smart door lock is not connected to the Internet, the terminal device displays the first password for the user to see. The user enters the first password into the smart door lock. After receiving the first password, the smart door lock decodes the first password using a preset algorithm to obtain a first lock time. During the first lock time, the smart door lock powers off the fingerprint module, card module, and face module to lock the smart door lock. This prevents unauthorized users from breaking the protection mechanism of the smart door lock through repeated trial and error or counterfeiting biometric information, thereby improving the security of the smart door lock.

[0052] See Figure 3 , which provides a timing diagram of the locking system of a smart door lock according to an embodiment of the present application. Take the interaction between the smart door lock and the terminal device as an example to describe, Figure 3As shown, the locking system shown may include the following steps:

[0053] S101, the terminal device obtains first control information of the smart door lock and a set first locking time;

[0054] Specifically, when the user needs to lock the smart door lock during use of the smart door lock, the user inputs the first control information of the smart door lock in the terminal device and sets the first locking time, so that the terminal device reads this information.

[0055] The first control information includes, but is not limited to, user information, the serial number of the smart door lock, and the manufacturer number of the smart door lock. The user information is the user's identity information set by the user when the smart door lock is used for the first time, and may include, but is not limited to, the user's name, age, and ID number.

[0056] The number of the smart door lock is the number assigned to the smart door lock by the manufacturer during production. This number is unique, similar to each person's ID number.

[0057] The manufacturer number of the smart door lock includes but is not limited to the name of the company that produces the smart door lock and the model of the smart door lock.

[0058] The first locking time includes a start time and an end time.

[0059] S102: The terminal device generates a first password based on the first control information and the first locking time, and sends the first password to the smart door lock;

[0060] Specifically, the terminal device generates a first password using a preset encryption algorithm according to the first control information input by the user and the first locking time.

[0061] Among them, the first password is a password generated by the terminal device based on the first control information of the smart door lock and the set first locking time. The first password may include but is not limited to numbers, uppercase and lowercase English letters, symbols, etc.

[0062] The preset encryption algorithm includes but is not limited to a symmetric encryption algorithm and an asymmetric encryption algorithm.

[0063] Symmetric encryption algorithms allow the decryption key to be derived from the encryption key, and vice versa. In most cases, the encryption and decryption keys are identical. Decryption is represented by EK(P) = C, and decryption is represented by DK(C) = P. P is the plaintext space, representing the set of all possible plaintexts; C is the ciphertext space, representing the set of all possible ciphertexts; K is the key space, a variable parameter in the encryption algorithm; E is the encryption algorithm, consisting of some formula, rule, or procedure; and D is the decryption algorithm, which is the inverse of E.

[0064] Asymmetric encryption algorithms use two keys for encryption and decryption, typically two keys, called a "public key" and a "private key." These two keys must be used in pairs to open the encrypted file. The "public key" here refers to a publicly available key, while the "private key" cannot be disclosed and is known only to the holder. Asymmetric encryption methods use two keys, and the public key is publicly available, making it safe for others to know. To decrypt the message, the recipient can simply use their private key, effectively avoiding key transmission security issues.

[0065] The first password is sent to the smart door lock. One possible way to implement this is that when the smart door lock is connected to the Internet, the first password can be sent directly to the smart door lock through the terminal device to lock the smart door lock.

[0066] Another feasible method is that when the smart door lock is not connected to the Internet, the terminal device displays the first password, and the user enters the first password into the smart door lock to lock the smart door lock.

[0067] S103, the smart door lock receives the first password;

[0068] Specifically, after receiving the first password, the smart door lock decodes the first password using a preset decryption algorithm to obtain the first lock time. The preset decryption algorithm is the inverse operation of the preset encryption algorithm, and is not specifically limited here.

[0069] Among them, the first password is a password generated by the terminal device based on the first control information of the smart door lock and the set first locking time. The first password may include but is not limited to numbers, uppercase and lowercase English letters, symbols, etc.

[0070] The smart door lock receives the first password. One possible implementation is that when the smart door lock is connected to the Internet, it can directly receive the first password sent by the terminal device.

[0071] Another feasible method is to receive the first password displayed on the terminal device input by the user when the smart door lock is not connected to the Internet.

[0072] S104: The smart door lock cuts off power to the fingerprint module, the card module, and the face module according to the first password within the first locking time to lock the door.

[0073] Specifically, the fingerprint module, the card module and the face module are powered off within the first locking time to lock the smart door lock.

[0074] The unlocking control module includes but is not limited to a digital password module, a fingerprint module, a card module, and a face module.

[0075] like Figure 4 The figure shows the power supply status of the unlocking control module of the smart door lock in normal mode. Each unlocking control module is powered normally, and the smart door lock can be unlocked by entering any password preset by the unlocking control module of the smart door lock.

[0076] like Figure 5 The figure shows the power supply status of the unlocking control module of the smart door lock in the locked mode. The fingerprint module, card module and face module are all powered off inside the smart door lock.

[0077] Among them, the digital unlocking password preset by the digital password module cannot unlock the smart door lock in the locked mode.

[0078] In an embodiment of the present application, when a user needs to lock a smart door lock, a first password is generated by inputting the first control information of the smart door lock and the set first lock time through a terminal device. If the smart door lock is connected to the Internet, the user can choose to send the first password to the smart door lock through the terminal device, or the user can enter the first password into the smart door lock himself. If the smart door lock is not connected to the Internet, the user can choose to enter the first password displayed on the terminal device into the smart door lock himself. After receiving the first password, the smart door lock decodes the first password using a preset algorithm to obtain a first lock time, and then powers off the fingerprint module, card module, and face module during the first lock time to lock the smart door lock. In this way, the smart door lock cannot be unlocked by the preset digital password during the first lock time, thereby preventing illegal users from damaging the protection mechanism of the smart door lock through multiple trial and error or counterfeiting biometric information, thereby improving the security of the smart door lock and saving power during the use of the smart door lock.

[0079] See Figure 6 , provides a flowchart of a locking method of a smart door lock according to an embodiment of the present application. Take the terminal device side as an example for description, such as Figure 6 As shown, the locking method may include the following steps:

[0080] S201, obtaining first control information of the smart door lock and a set first locking time;

[0081] Specifically, when the user needs to lock the smart door lock during use of the smart door lock, the user inputs the first control information of the smart door lock in the terminal device and sets the first locking time, so that the terminal device reads this information.

[0082] The first control information includes, but is not limited to, user information, the serial number of the smart door lock, and the manufacturer number of the smart door lock. The user information is the user's identity information set by the user when the smart door lock is used for the first time, and may include, but is not limited to, the user's name, age, and ID number.

[0083] The number of the smart door lock is the number assigned to the smart door lock by the manufacturer during production. This number is unique, similar to each person's ID number.

[0084] The manufacturer number of the smart door lock includes but is not limited to the name of the company that produces the smart door lock and the model of the smart door lock.

[0085] The first locking time includes a start time and an end time.

[0086] S202, generating a first password based on the first control information and the first locking time, so that when the smart door lock receives the first password, the fingerprint module, the card module and the face module are powered off within the first locking time to lock them.

[0087] Specifically, the terminal device generates a first password using a preset encryption algorithm according to the first control information input by the user and the first locking time.

[0088] The preset encryption algorithm includes but is not limited to a symmetric encryption algorithm and an asymmetric encryption algorithm.

[0089] Symmetric encryption algorithms allow the decryption key to be derived from the encryption key, and vice versa. In most cases, the encryption and decryption keys are identical. Decryption is represented by EK(P) = C, and decryption is represented by DK(C) = P. P is the plaintext space, representing the set of all possible plaintexts; C is the ciphertext space, representing the set of all possible ciphertexts; K is the key space, a variable parameter in the encryption algorithm; E is the encryption algorithm, consisting of some formula, rule, or procedure; and D is the decryption algorithm, which is the inverse of E.

[0090] Asymmetric encryption algorithms use two keys for encryption and decryption, typically two keys, called a "public key" and a "private key." These two keys must be used in pairs to open the encrypted file. The "public key" here refers to a publicly available key, while the "private key" cannot be disclosed and is known only to the holder. Asymmetric encryption methods use two keys, and the public key is publicly available, making it safe for others to know. To decrypt the message, the recipient can simply use their private key, effectively avoiding key transmission security issues.

[0091] The first password is a password generated by the terminal device based on the first control information of the smart door lock and the set first locking time. The first password may include but is not limited to numbers, uppercase and lowercase English letters, symbols, etc.

[0092] The first password is sent to the smart door lock. One possible way to implement this is that when the smart door lock is connected to the Internet, the first password can be directly sent to the smart door lock through the terminal device to lock the smart door lock within the first locking time.

[0093] Another feasible way is that when the smart door lock is not connected to the Internet, the user can choose to input the first password displayed on the terminal device into the smart door lock to lock the smart door lock within the first locking time.

[0094] In an embodiment of the present application, when a user needs to lock a smart door lock, the terminal device inputs the first control information of the smart door lock and the set first lock time through the terminal device, and the terminal device generates a first password based on this information. When the smart door lock is connected to the Internet, the user can choose to send the first password to the smart door lock through the terminal device, and power off the fingerprint module, card module, and face module in the smart door lock to achieve remote control and lock the smart door lock within the first lock time. When the smart door lock is not connected to the Internet, the user can enter the first password displayed on the terminal device into the smart door lock, and power off the fingerprint module, card module, and face module in the smart door lock to achieve locking the smart door lock within the first lock time. Because the first control information input by the user is unique, the generated first password is also unique, which provides higher security when locking the smart door lock.

[0095] See Figure 7 , provides a flowchart of a locking method of a smart door lock according to an embodiment of the present application. Take the smart door lock side as an example for description, as shown in FIG. Figure 7 As shown, the locking method may include the following steps:

[0096] S301, obtaining first control information of the smart door lock and a set first locking time;

[0097] The specific implementation of this step can refer to step 201 and will not be described in detail here.

[0098] S302, generating a first password based on the first control information and the first locking time, so that when the smart door lock receives the first password, it is locked within the first locking time;

[0099] The specific implementation of this step can refer to step 202 and will not be described in detail here.

[0100] S303: After the first locking time ends, a prompt message is displayed asking whether to end the locking.

[0101] Specifically, after the smart door lock is locked, when the first locking time ends, Figure 8 As shown, the terminal device will display a prompt message whether to end the lock, and you can choose to confirm or deny the end of the lock according to the prompt message.

[0102] When the confirmation command is selected, the first locking time ends and the smart door lock does not receive the command to continue locking, the smart door lock will end the locking within the first locking time and power the unlocking control module of the smart door lock. The user only needs to enter any unlocking password information preset in the unlocking control module to unlock the smart door lock and then enter the room.

[0103] Among them, the unlocking control module includes but is not limited to a digital password module, a fingerprint module, a card module, and a face module.

[0104] S304, in response to a denial instruction of the prompt information, obtaining a set second lock time;

[0105] Specifically, such as Figure 9 As shown, when the deny instruction is selected, the fingerprint module, card module and face module will be controlled to continue to be powered off to lock them, and the user sets a second locking time on the terminal device.

[0106] The second locking time may include a start time and an end time, and the start time of the second locking time may be the end time of the first locking time.

[0107] S305, generating a second password based on the first control information and the second locking time, so that when the smart door lock receives the second password, the fingerprint module, the card module, and the face module continue to be powered off to lock;

[0108] Specifically, the terminal device generates the second password using a preset algorithm according to the second locking time and the first control information input by the user.

[0109] One possible way to send the second password to the smart door lock is as follows: Figure 10 As shown, when the smart door lock is connected to the Internet, you can choose to send the second password to the smart door lock through the terminal device to continue to power off the fingerprint module, card module and face module for locking.

[0110] Another possible way to achieve this is, Figure 11As shown, when the smart door lock is not connected to the Internet, the user can choose to enter the second password displayed on the terminal device into the smart door lock to continue to power off the fingerprint module, card module and face module to lock it.

[0111] In an embodiment of the present application, at the end of the first locking time of the smart door lock, the terminal device will display a prompt message whether to end the locking of the smart door lock. Two options are displayed in the prompt message. When the user chooses to end the locking of the smart door lock, the smart door lock will power its internal unlocking control module. At this time, the user only needs to enter any unlocking password preset by the unlocking control module to unlock the smart door lock and enter the room; when the user needs to continue locking the smart door lock, it is necessary to set a second locking time in the terminal device. The terminal device generates a second password based on the second locking time and the first control information. When the smart door lock is connected to the network, the terminal device can be selected to directly send the second password to the smart door lock to realize remote control of continued locking of the smart door lock; when the smart door lock is not connected to the network, the user can choose to enter the second password displayed by the terminal device into the smart door lock to realize continued locking of the smart door lock.

[0112] See Figure 12 , is a flowchart of a method for unlocking a smart door lock proposed in an embodiment of the present application. Take the smart door lock side as an example for description, Figure 12 As shown, the locking method may include the following steps:

[0113] S401, obtaining first control information of the smart door lock and a set first locking time;

[0114] The specific implementation of this step can refer to step 201 and will not be described in detail here.

[0115] S402, generating a first password based on the first control information and the first locking time, so that the smart door lock is locked within the first locking time when receiving the first password;

[0116] The specific implementation of this step can refer to step 202 and will not be described in detail here.

[0117] S403: The smart door lock receives an unlocking request for the smart door lock within the first locking time;

[0118] Specifically, when the user needs to end the locking of the smart door lock within the first locking time, a related unlocking request can be sent in the terminal device.

[0119] When the terminal device receives an unlock request from the user, a filling box and a selection box pop up.

[0120] The fill-in box needs to fill in the user's information and the second control information of the smart door lock to improve security.

[0121] The second control information is at least one item in the control information of the smart door lock that is the same as or different from the first control information, and may include but is not limited to user information, the number of the smart door lock, and the manufacturer number of the smart door lock.

[0122] The user information is the information set by the user when the smart door lock is used for the first time to prove the user's identity, which may include but is not limited to the user's name, user age, and user ID number.

[0123] The number of the smart door lock is the number assigned to the smart door lock by the manufacturer during production. This number is unique, similar to each person's ID number.

[0124] The manufacturer number of the smart door lock includes but is not limited to the name of the company that produces the smart door lock and the model of the smart door lock.

[0125] In the selection box, the user needs to select the smart door lock number and the first locking time in order to accurately unlock the smart door lock within the locking time period of the smart door lock number.

[0126] The locking time is set by the user when he needs to lock the smart door lock.

[0127] S404, obtaining information carried in the unlock request;

[0128] Specifically, after the user sends an unlock request, the terminal device parses the information carried in the request through a preset algorithm.

[0129] The information carried may include but is not limited to the user information entered by the user, the second control information, the number of the smart door lock and the first locking time.

[0130] The first locking time may include a start time and an end time.

[0131] S405, generating a cancellation code according to the information carried in the unlocking request, so that when the smart door lock receives the cancellation code, it supplies power to the fingerprint module, the card module and the face module to unlock the door.

[0132] Specifically, when the second control information is the same as the first control information or both belong to the control information of the same smart door lock number, the terminal device generates a cancellation code through a preset algorithm based on the information carried in the request.

[0133] Send the cancellation code to the smart door lock. One possible way to do this is: Figure 13As shown, when the smart door lock is connected to the Internet, you can choose to send the cancellation code directly to the smart door lock through the terminal device, or you can choose to enter the cancellation code displayed on the terminal device into the smart door lock yourself, and power the fingerprint module, card module and face module to unlock the smart door lock within the first locking time.

[0134] Another possible way to achieve this is, Figure 14 As shown, when the smart door lock is not connected to the Internet, the user can choose to enter the cancellation code displayed on the terminal device into the smart door lock, power the fingerprint module, card module and face module to unlock the smart door lock within the first locking time.

[0135] It is understandable that if Figure 15 As shown, when someone tries to unlock the smart door lock with a preset digital password within the first locking time, the terminal device will receive an abnormal unlocking reminder sent by the smart door lock. After receiving the abnormal unlocking reminder, the terminal device can output a reminder to the user in the form of text message prompts, sound broadcasts, flashing signal lights, and forced vibrations, but not limited to the above forms, thereby realizing real-time monitoring of the status of the smart door lock within the first locking time and improving the security of the smart door lock when locked.

[0136] In an embodiment of the present application, when a user needs to unlock the smart door lock within the first locking time, the terminal device sends an unlock request and enters the user's information, the smart door lock number and the first locking time. The terminal device generates a cancellation code based on the information carried in the unlock request. When the smart door lock is connected to the network, the terminal device can be selected to directly send the cancellation code and the second control information to the smart door lock. When the smart door lock is not connected to the network, the user can choose to input the cancellation code and the second control information displayed by the terminal device into the smart door lock. When the second control information matches the first control information, the fingerprint module, the card module and the face module are powered to unlock the smart door lock within the first locking time. When an illegal user attempts to unlock the smart door lock within the first locking time, the smart door lock will sound an alarm and send an abnormal unlocking reminder notification to the terminal device to remind the user, thereby realizing real-time monitoring of the smart door lock by the user within the first locking time and improving the security of the smart door lock when locked.

[0137] It should be noted that the unlocking method provided in the above embodiment is only illustrated by the example of unlocking after locking within the above-mentioned first locking time. In actual application, after the smart door lock is further locked, it is necessary to unlock the smart door lock within the set locking time. It belongs to the same concept. The implementation process is detailed in the embodiment of the unlocking method after locking within the first locking time, which will not be repeated here.

[0138] See Figure 16 , a flowchart of a locking method of a smart door lock is provided for an embodiment of the present application. Take the smart door lock side as an example for description, such as Figure 16 As shown, the locking method may include the following steps:

[0139] S501, receiving a first password, wherein the first password is a password generated by a terminal device based on first control information of the smart door lock and a set first locking time;

[0140] The first password may include but is not limited to numbers, uppercase and lowercase English letters, symbols, etc.

[0141] Specifically, a possible way for the smart door lock to receive the first password is that when the smart door lock is connected to the Internet, it can choose to directly receive the first password sent directly by the terminal device.

[0142] Another feasible method is that when the smart door lock is not connected to the Internet, you can choose to receive the first password displayed by the terminal device input by the user.

[0143] S502: According to the first password, the fingerprint module, the card module, and the face module are powered off within the first locking time to lock them.

[0144] Specifically, the smart door lock decodes the first password using a preset decryption algorithm to obtain a first lock time, and then powers off the fingerprint module, card module, and face module to lock the smart door lock during the first lock time. This preset decryption algorithm is the inverse of the encryption algorithm preset in step S202 and is not specifically limited here.

[0145] The unlocking control module includes but is not limited to a digital password module, a fingerprint module, a card module, and a face module.

[0146] The smart door lock is locked by powering off the fingerprint module, card module, and face module of the smart door lock. After locking, the smart door lock cannot be unlocked using the digital unlocking password preset in the digital password module.

[0147] It is understandable that if Figure 7 In the process, when the user chooses to continue locking the smart door lock, the terminal device generates a second password according to the second locking time and the first control information input by the user, and sends the second password and the second control information to the smart door lock. When the smart door lock receives the second password, the smart door lock decodes it through a preset decryption algorithm to obtain the second locking time, and continues to cut off the power to the fingerprint module, card module and face module within the second locking time to lock the smart door lock.

[0148] In an embodiment of the present application, the smart door lock decodes the first password directly sent by the terminal device when the smart door lock is connected to the Internet, or the first password displayed by the terminal device when the smart door lock is not connected to the Internet, through a preset decryption algorithm, to obtain a first locking time, and locks the smart door lock within the first locking time by powering off the fingerprint module, card module, and face module. When the user chooses to continue locking the smart door lock, the smart door lock continues to power off the fingerprint module, card module, and face module to lock the smart door lock within the set locking time based on the received second password and second control information. When the second control information matches the first control information, the smart door lock is prevented from attempting to destroy the protection mechanism of the smart door lock through technical means such as multiple password trials or counterfeiting biometric information, thereby improving the security of the smart door lock during the locking period and saving power during the use of the smart door lock.

[0149] See Figure 17 , provides a flow chart of a method for unlocking a smart door lock according to an embodiment of the present application. Take the smart door lock side as an example for description, as shown in FIG. Figure 17 As shown, the unlocking method may include the following steps:

[0150] S601, receiving a first password, wherein the first password is a password generated by a terminal device based on first control information of the smart door lock and a set first lock time;

[0151] The specific implementation of this step can refer to step 501 and will not be described in detail here.

[0152] S602: According to the first password, the fingerprint module, the card module, and the face module are powered off within the first locking time to lock them.

[0153] The specific implementation of this step can refer to step 502 and will not be described in detail here.

[0154] S603, receiving a cancellation code and second control information within the first locking time, wherein the cancellation code is generated by the terminal device based on the first control information of the smart door lock and the set first locking time;

[0155] Specifically, when the user needs to unlock the smart door lock within the first locking time, he needs to send an unlocking request on the terminal device and enter the user's information, the smart door lock number and the first locking time. The terminal device generates a cancellation code based on the smart door lock number and the first locking time entered by the user, and sends the cancellation code and the second control information of the smart door lock to the smart door lock.

[0156] One possible way to achieve this is, Figure 13 As shown, when the smart door lock is connected to the Internet, you can choose to receive the cancellation code and the second control information sent by the terminal device to the smart door lock, and power the fingerprint module, card module and face module to unlock it.

[0157] Another possible way to achieve this is, Figure 14 As shown, when the smart door lock is not connected to the Internet, it can choose to receive the cancellation code displayed by the terminal device input by the user and the second control information to the smart door lock, and power the fingerprint module, card module and face module to unlock.

[0158] The user information is the information that the user sets when the smart door lock is used for the first time to prove the user's identity, which may include but is not limited to the user's name, user age, and user ID number. The first locking time may include a start time and an end time.

[0159] The second control information is at least one item of the control information belonging to the same smart door lock that is the same as or different from the first control information, and may include but is not limited to user information, the number of the smart door lock, and the manufacturer number of the smart door lock.

[0160] Among them, the manufacturer number of the smart door lock includes but is not limited to the name of the company that produces the smart door lock and the model of the smart door lock.

[0161] S604: When the second control information matches the first control information, power is supplied to the fingerprint module, the card module, and the face module according to the received cancellation code;

[0162] Specifically, the second control information is matched with the first control information. If the second control information is the same as the first control information or belongs to the control information of the smart door lock with the same number as the first smart door lock, after the match is successful, Figure 5 The lock mode shown is restored to Figure 4 In the normal mode shown, power is supplied to the fingerprint module, card module and face module.

[0163] like Figure 4 As shown, in normal mode, each unlocking control module of the smart door lock is powered normally, and the smart door lock can be unlocked by entering any unlocking password preset by the unlocking control module. Figure 5 As shown, in the lock mode, the fingerprint module, card module and face module of the smart door lock are all powered off inside the smart door lock to lock the smart door lock within the first lock time.

[0164] S605: Unlock the smart door lock based on a preset unlocking password.

[0165] Specifically, any preset unlocking password is input into the unlocking control module of the smart door lock to unlock the smart door lock.

[0166] In an embodiment of the present application, when the user needs to unlock the smart door lock within the first locking time, an unlock request is sent in the terminal device, and the terminal device generates a cancellation code based on the information carried in the user's request. When the smart door lock is connected to the network, you can choose to receive the cancellation code and the second control information sent by the terminal device. When the smart door lock is not connected to the network, you can choose to receive the cancellation code and the second control information displayed by the terminal device input by the user. After the received second control information successfully matches the first control information, the fingerprint module, card module and face module of the corresponding smart door lock are powered according to the cancellation code. After any unlock password preset by the unlock control module is entered into the smart door lock, the smart door lock can be unlocked and the user can enter the room, which increases the complexity of unlocking the smart door lock and improves the safety of the smart door lock during use.

[0167] It should be noted that the method for unlocking the smart door lock within the locking time provided in the above embodiment is only illustrated by the example of unlocking the smart door lock by receiving a cancellation code within the first locking time. In actual applications, the smart door lock can be further locked as needed, and then unlocked by receiving a cancellation code within the set locking time. This belongs to the same concept. The implementation process is detailed in the embodiment of the method for unlocking the smart door lock by receiving a cancellation code within the first locking time of the smart door lock, which will not be repeated here.

[0194] In an embodiment of the present application, when a user needs to lock a smart door lock, a first password is generated by inputting the first control information of the smart door lock and the set first lock time through a terminal device. If the smart door lock is connected to the Internet, the user can choose to send the first password to the smart door lock through the terminal device, or the user can enter the first password into the smart door lock himself. If the smart door lock is not connected to the Internet, the user can choose to enter the first password displayed on the terminal device into the smart door lock himself. After receiving the first password, the smart door lock decodes the first password through a preset decryption algorithm to obtain the first lock time. Then, during the first lock time, the fingerprint module, card module, and face module are powered off to lock the smart door lock. During the first lock time, the digital password preset in the digital password module cannot unlock the smart door lock. At the same time, it prevents illegal users from destroying the protection mechanism of the smart door lock through technical means such as repeated trial and error or counterfeiting biometric information, thereby improving the security of the smart door lock and making the smart door lock more energy-efficient during use.
