Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent locks, and in particular to a dual-mode operation and emergency control method of a passive lock and a control system thereof. BACKGROUND

[0002] With the rapid development of Internet of Things technology, intelligent locks are increasingly widely used in daily life and industrial production. Traditional mechanical locks rely on physical keys, which have problems such as easy loss, easy duplication, and inconvenient management. Although existing intelligent locks have solved these problems to some extent, there is still room for improvement in terms of flexibility of operation mode, emergency handling capability, and security.

[0003] Some intelligent locks only support a single registration and use mode, and users must complete a cumbersome registration process to use them, which greatly inconveniences temporary visitors or use in emergency situations. Some other intelligent locks support registration-free use, but have deficiencies in permission management and security, making it difficult to meet the use requirements in different scenarios. At the same time, in the event of a malfunction of the intelligent lock or the inability of the APP to function normally, there is a lack of effective emergency unlocking and control means, which may prevent users from using the lock normally and cause unnecessary trouble and loss.

[0004] Therefore, developing a passive lock system with dual-mode operation, flexible permission management, and reliable emergency control functions has become an important research direction in the field of intelligent locks. SUMMARY

[0005] In order to overcome the above-mentioned deficiencies of the prior art, the present application provides a dual-mode operation and emergency control method of a passive lock and a control system thereof to solve the problems of single operation mode, insufficient emergency handling capability, and security and flexibility of existing intelligent locks.

[0074] In order to meet the individual needs of users, the passive lock is suitable for any one or more of the registration-free direct use mode, the registered use mode and the electronic key emergency operation mode. It is worth mentioning that the electronic control system 14 in the passive lock can be pre-installed with the program of the registration-free direct use mode or / and the registered use mode or / and the electronic key emergency operation mode when it is produced and manufactured. Therefore, when the passive lock has any one or more of the foregoing modes, it belongs to the protection scope of the technical scheme of the present application.

[0079] In order to facilitate the use of the passive lock by the visitor, a preferred embodiment of the present application is as follows:

[0080] I. In the registration-free public mode of step T13, the passive lock is open to all terminal devices installed with the passive lock control APP; in the registration-free private mode of step T13, the terminal device of the user itself matches the electric control system 14 in the passive lock to form a first master mode terminal device, and the first master mode terminal device can generate an encrypted temporary password through the passive lock control APP, and the encrypted temporary password can be pushed to a specified and unique third-party terminal device; after the third-party terminal device establishes a communication connection with the electric control system 14 in the passive lock, a first guest mode terminal device is formed, and the first guest mode terminal device obtains temporary unlocking permission for the passive lock through the encrypted temporary password. This mode is suitable for scenes such as temporary visitors in the family, and the master can generate a temporary password for the guest, avoiding the handover of the key.

In the step T23 registration public mode, the passive lock opens to all terminal devices installed with passive lock control APP and completes registration and login operation; in the step T23 registration private mode, the terminal device of the user itself matches with the electric control system 14 in the passive lock to form a second master mode terminal device, and the second master mode terminal device can generate an encrypted temporary password through the passive lock control APP, and the encrypted temporary password can be pushed to any third-party terminal device; the third-party terminal device establishes a communication connection with the electric control system 14 in the passive lock and completes registration and login operation to form a second guest mode terminal device, and the second guest mode terminal device obtains temporary unlocking permission of the passive lock through the encrypted temporary password. This mode is suitable for the scene that the department head temporarily authorizes other department personnel to enter a specific area in an enterprise.

[0082] It should be emphasized that the encrypted temporary password is related, and the encoding content of the encrypted temporary password is an encrypted fingerprint value with lock ID, permission validity, and user terminal device fingerprint. The third-party terminal device needs to verify whether the encrypted fingerprint value matches through the passive lock control APP after obtaining the encrypted fingerprint value, and if it matches correctly, the temporary unlocking permission can be obtained. The lock ID is used to identify the corresponding lock, ensuring the uniqueness of the password; the permission validity specifies the effective use time of the password, which automatically expires after expiration; and the user terminal device fingerprint is used to bind with the terminal device to prevent the password from being used by other devices. The third-party terminal device needs to verify whether the encrypted fingerprint value matches through the passive lock control APP after obtaining the encrypted fingerprint value, and if it matches correctly, the temporary unlocking permission can be obtained.

[0083] In step T3, the forced unlocking / deleting binding instruction sent by the electronic key is an instruction containing lock ID, timestamp, and encrypted signature; the electric control system 14 in the passive lock needs to comprehensively verify the validity of the timestamp, the matching of the lock ID and the encrypted signature (preferably using the encrypted signature of the national secret SM4), and if the verification is correct, the unlocking instruction can be executed. There are many electronic keys and passive locks, and through the instruction containing the lock ID, timestamp, and encrypted signature, it can be ensured that the passive lock and its adapted electronic key can be accurately adapted, preventing attacks and forced opening by unadapted electronic keys.

A terminal device: a passive lock control APP is installed, and the passive lock control APP supports local operation without registration and registration login interaction, wherein the local operation without registration matches the direct use mode without registration, and the registration login interaction matches the registration use mode; wherein the terminal device can be a mobile phone, a smart bracelet or watch, a mobile computer or the like. A background server: having a permission management module, which is used for deploying user management (registration information, login state, etc. of the user), lock management (used for managing the basic information and state of the lock), permission allocation (used for allocating corresponding operation permissions to different users and terminal devices), a log audit module (used for recording and auditing the operation log of the lock, facilitating traceability and management), storing user information, lock data and full operation log, and the background server is suitable for the registration use mode. An electronic key: which is internally provided with a battery, a near field communication module and a security chip (preferably a national security chip), and after security authentication, sends a forced unlocking and deleting binding instruction to the electric control system 14 in the passive lock body 1. Wherein the security chip is used for encrypting and signing the instruction to ensure the security and legality of the instruction. Wherein the electronic key can be adapted to and interactively used with the electric control system (14) without the direct use mode without registration or / and the registration use mode; or can be adapted to and interactively used with the electric control system (14) with the direct use mode without registration or / and the registration use mode.

[0088] The passive lock management and control system is adopted, the near field communication module is used for near field communication with the terminal device and the electronic key, realizing data transmission and interaction; the storage module stores the information of the electronic key and the lock; the lock white list is used for limiting that only specific electronic keys can operate the lock, improving the security; the control module is used for controlling the unlocking and locking operations of the lock according to the received instruction; the passive lock control APP is installed on the terminal device, and the user realizes various operations and management of the passive lock through the passive lock control APP on the terminal device.

[0089] Therefore, the storage module of the passive lock body 1 stores a lock white list of electronic keys, local binding data of the lock, and temporary unlocking permission parameters; and the control module is used for verifying the legality of the encrypted fingerprint value in the encrypted temporary password.

[0090] On the other hand, the permission management module of the background server supports: 1, pre-authorization mode: write the electronic key ID into the lock white list, supporting single import or batch import; 2, dynamic authorization mode: generate a time-limited authorization code (the effective period can be specified, for example, the effective period is less than or equal to 2 hours), and the electronic key performs near field communication with the passive lock through the built-in passive lock control APP to obtain temporary unlocking permission.

It is worth mentioning that the background server can not only encrypt the encrypted temporary password, but also encrypt all data exchanged between the terminal device / passive lock and the background server.

[0092] More specifically, referring to Figures 3-4 , the passive lock body 1 comprises: a mounting shell 11 fixed to a door cabinet body; a lock shell 12 rotatably assembled to the lock shell 12 on the mounting shell 11; a locking member 13 assembled to the lock shell 12 and in transmission cooperation with the lock shell 12, the locking member 13 has at least an unlocking position state and a locking position state; and an electric control system 14 arranged in the lock shell 12. It is worth mentioning that the terminal device or electronic key is in communication connection with the passive lock when approaching the passive lock and provides power supply to the passive lock.

[0093] The power supply and communication scheme that can be used is:

[0094] Power supply end (terminal device / electronic key 2) circuit: 1, energy emission module: containing transmitting coil L1, drive chip U1 (such as "NFC / BLE energy drive"), current limiting resistor R1; 2, control unit: MCU (such as "STM32 series") connected to the drive chip, output PWM signal to control the energy emission intensity; communication module: 3, RF chip U2 (such as "BLE5.0 / NFC controller") and MCU bidirectional communication, through the coupling capacitor C1 connected to the transmitting coil L1 (multiplexing communication and power supply coil).

[0096] Summarizing, signal and energy path:

[0097] Referring to Figure 5 , electric energy flow: L1 → electromagnetic induction → L2 → D1-D4 rectification → C2 energy storage → U3 voltage stabilization → MCU and motor;

[0098] Information flow: terminal / key MCU → U2 → L1 (carrier modulation) → L2 → U4 demodulation → passive lock MCU (the reverse is the same, realizing bidirectional communication).

[0099] The specific application scenario of the application is as follows:

[0100] I. Implementation case of registration-free direct use mode: taking a shared locker in a study room as an example, the locker uses a passive lock and supports registration-free direct use mode.

[0101] After the user installs the passive lock control APP on the mobile phone, opens the APP, and establishes a connection with the passive lock of the locker through Bluetooth (step T11). At this time, the passive lock is in registration-free public mode, and the user can directly send an encrypted unlocking instruction to open the locker (step T12), and after storing the items, send a lock closing instruction to close the locker.

[0102] When the self-service room manager needs to manage a specific locker, he switches it to the private mode by APP (step T13), and his phone becomes the first master mode terminal. When a student needs to use the locker temporarily, the manager generates a temporary password by APP and pushes it to the student's phone. The student's phone connects with the passive lock and becomes the first guest mode terminal, and inputs the password to get the temporary unlocking permission.

[0103] The manager can add the locker to be managed by scanning the code by APP (step T14), and can query the local unlocking record of the locker to understand the usage. If the locker fails, the manager can trigger the factory reset operation to reset the locker.

[0104] II. Implementation case of registered use mode: a company's file cabinet uses passive lock and supports registered use mode.

[0105] The employee installs the passive lock control APP on his phone, obtains the verification information from the background server by mobile phone, completes registration and logs in to the APP (step T21). Open the APP, connect with the passive lock of the file cabinet through NFC, send the encrypted unlocking instruction to open the file cabinet (step T22), and send the lock instruction after taking or placing the file.

[0106] The file cabinet is in the registered public mode by default, and all registered employees can use it. When the department manager needs to manage the important file cabinet, he switches it to the registered private mode by APP (step T23), and the manager's phone becomes the second master mode terminal. When other department employees need to check the file, the manager generates an encrypted temporary password and pushes it to the employee. The employee registers and logs in to the APP, connects with the passive lock, and inputs the password to get the temporary unlocking permission.

[0107] The manager adds the file cabinet by scanning the code by APP (step T24), can dissociate with the employee who has left the company, remove the full data of the file cabinet, query the unlocking record, and trigger the factory reset operation when necessary.

[0108] III. Implementation case of emergency operation mode of electronic key: a family's door uses passive lock and is equipped with an electronic key as an emergency tool.

[0109] One day, the owner's phone is lost and he cannot open the door by APP, so he uses the electronic key. The electronic key connects with the passive lock through near field communication (step T31), and sends the forced unlocking instruction containing the lock ID, timestamp and encrypted signature. The electronic control system 14 of the passive lock verifies the correctness of the instruction, and executes the unlocking operation (step T32), so that the owner can enter the house.

[0110] For safety, the master performs a delete binding operation on the electronic key (step T33), clears the local binding data of the lock and the associated data in the background server, and restores the lock to the "unbound" state, and then re-performs the binding setting.

[0111] Four, the case of the system parts working together: when the user generates an encrypted temporary password in the registration private mode through the APP of the terminal device, the APP generates an encrypted fingerprint value based on the fingerprint of the user terminal device and the fingerprint of the passive lock body 1, and sends it to the background server (terminal device and background server work together). The background server returns it to the APP after encryption processing (background server works). The user pushes the password to the third party, and the terminal device of the third party establishes a connection with the passive lock, inputs the password, and the control module of the passive lock verifies the legality of the password (passive lock body 1 works). After verification, it allows the lock to be opened. At the same time, the background server records the log of this unlocking operation (background server works).

[0112] When the electronic key forcibly opens the lock, the electronic key sends an instruction, the near field communication module of the passive lock receives the instruction and transmits it to the control module, the control module verifies the instruction (passive lock body 1 works), and controls the lock to be opened after verification. At the same time, the security chip of the electronic key ensures the safety of the instruction (electronic key works).

[0113] The above is only a preferred embodiment of the present application, not any limitation on the present application, any simple modification, change and equivalent structure change according to the technical essence of the application to the above embodiment are still within the protection scope of the technical solution of the present application.
