Description

Technical Field

[0001] This utility model relates to the field of smart lock technology, and in particular to a smart lock control device with dual systems. Background Technology

[0002] With the continuous development of smart home technology, smart door locks, as an important component of home security, have attracted much attention for their functionality and performance. Current smart lock designs often employ a front panel main controller as the master device, with other peripheral circuits (including the rear panel main controller) acting as slave devices. However, in practical applications, the front panel, located outside the door, is vulnerable to damage, and its environment is complex, variable, and difficult to control. On one hand, malicious vandalism is frequent; criminals may directly damage the front panel through forceful prying or impacts, thereby disrupting the internal circuitry and main control system. On the other hand, the impact of external environmental factors on the front panel cannot be ignored. For example, in northern regions, the temperature difference between indoors and outdoors is extreme in winter. When warm, humid air encounters the cold surface of the front panel, condensation easily forms. Once this condensation seeps into the electronic components and circuits inside the front panel, it can cause serious problems such as short circuits and corrosion, directly leading to the failure of the front panel main controller.

[0033] like Figures 1 to 3 As shown in the embodiment of this utility model, it includes a front panel and a rear panel. The front panel includes a front panel judgment and control module and a front panel information acquisition module. The rear panel includes a rear panel judgment and control module and a rear panel information acquisition module. The front panel judgment and control module is connected to the front panel information acquisition module, and the rear panel judgment and control module is connected to the rear panel information acquisition module. The front panel judgment and control module and the rear panel judgment and control module are also communicatively connected.

[0034] The front panel information acquisition module is used to collect unlocking information when the user is outside the door;

[0035] The rear panel information acquisition module is used to collect lock and unlock information when the user is inside the door and wireless unlock information when the user is outside the door;

[0036] The front panel judgment and control module is used to transmit unlocking information to the rear door control module;

[0037] The rear door control module is used to open and close the door based on unlocking information, wireless unlocking information, and lock opening / closing information.

[0038] It is understood that this utility model is a dual-system design. Regardless of whether the front panel judgment control module or the rear panel judgment control module is in master mode or slave mode, it can still solve the problem of the entire door lock failing to open or close due to damage to the front panel or abnormal communication between the front and rear panels. The first system is dominated by the front panel, and the second system is dominated by the rear panel.

[0039] In this embodiment, the front board judgment control module and the rear board judgment control module can be any multi-interface chip with communication function. In this embodiment, the chip used for the front board judgment control module is NSS32LLOCK-1; and the chip used for the rear board judgment control module is N32WB031KEQ6-2.

[0040] The front panel information acquisition module includes a fingerprint module, a button module, a card swiping module, a voice module, and a recognition module, and the fingerprint module, button module, card swiping module, voice module, and recognition module are respectively connected to the front panel judgment and control module.

[0041] It is understood that in this embodiment, the fingerprint module can use any chip with fingerprint acquisition function, the card swiping module can use any chip with card swiping function, the voice module can use any chip with voice acquisition function, and the recognition module includes face recognition. In this embodiment, the fingerprint module can use AS602 chip, P1032BF1 chip, or integrated chip; the card swiping module can use FM17580, FM17611, FM17622, ​​BaiShui 850, or integrated microcontroller; the voice module uses NVG040W, NV512F, or other voice chips, or integrated chip; and the face recognition module can use an external camera.

[0042] It includes a communication status monitoring module, which is connected to the front panel judgment control module and the rear panel judgment control module respectively, and is used to monitor the communication status of the front panel judgment control module and the rear panel judgment control module.

[0043] The back panel includes a mode switching module, which is connected to the back panel judgment and control module and the communication status monitoring module respectively, and is used to control the back panel judgment and control module to be in host mode or slave mode according to the communication status.

[0044] When the communication status is normal, the back panel judgment and control module is in slave mode, and the back panel judgment and control module opens and closes the door according to the unlocking information and the lock opening and closing information.

[0045] When the communication status is abnormal, the back panel judgment and control module is in host mode, and the back panel judgment and control module opens and closes the door according to the wireless unlocking information and the lock opening and closing information.

[0046] It is understandable that, regardless of whether the communication status is normal or abnormal, this utility model always operates in a single master device control mode, effectively avoiding the coordination chaos caused by multiple commands through centralized control.

[0047] In this embodiment, the mode switching module is a built-in function of the rear panel judgment and control module, and the communication status monitoring module is a built-in function of both the front panel judgment and control module and the rear panel judgment and control module.

[0048] The rear panel information acquisition module includes a door opening / closing button module and a wireless communication module;

[0049] The door opening / closing button module is used to collect lock opening / closing information based on the button status;

[0050] The wireless communication module is used to collect wireless unlocking information based on communication with the user.

[0051] It is understood that in this embodiment, the wireless communication module uses a Bluetooth module or a WIFI module for communication.

[0052] The system includes a power management module, which includes a power wake-up module. The power wake-up module is connected to the front panel judgment and control module and the rear panel judgment and control module, respectively. It is used to control the rear panel judgment and control module or the front panel judgment and control module to switch from a sleep state to a working state according to the wake-up signal issued by the front panel judgment and control module or the rear panel judgment and control module.

[0053] It is understood that this utility model is in a sleep state when it is not working. When one of the front board judgment control module and the rear board judgment control module receives user information, it switches from the sleep state to the working state. At the same time, the other control module is switched from the sleep state to the working state through the interrupt wake-up control line.

[0054] In this embodiment, the power wake-up module is an interrupt wake-up control line connected between the front board judgment control module and the rear board judgment control module. The front board judgment control module or the rear board judgment control module wakes up the other judgment control module through this interrupt wake-up control line.

[0055] The power management module includes a power restart module, which is connected to the front board judgment control module and the rear board judgment control module respectively, and is used to control the rear board or the front board to restart according to the restart signal issued by the front board judgment control module or the rear board judgment control module.

[0056] Understandably, in smart lock systems, the front and back panels are susceptible to external interference, such as vandalism or environmental factors, which may lead to program malfunctions or communication anomalies. When these problems occur, a restart can reinitialize the system, clear temporary error states, and restore the system to normal operation.

[0057] In this embodiment, the power restart module is a power control line connected between the front panel judgment control module and the rear panel judgment control module. The front panel judgment control module or the rear panel judgment control module restarts the other judgment control module through this power control line.

[0058] It includes a communication status determination module, which is connected to the communication status monitoring module, the front panel determination control module and the rear panel determination control module respectively;

[0059] The communication status judgment module is used to obtain the communication status based on the comparison result of the number of times communication is established between the front board judgment control module and the rear board judgment control module with a predetermined number of times.

[0060] When the number of communication establishments is less than the predetermined number, the front panel judgment control module and the rear panel judgment control module successfully communicate, and the communication status judgment module transmits the normal communication status to the communication status monitoring module.

[0061] When the number of communication establishments equals the predetermined number, the front board judgment control module or the rear board judgment control module will send a restart signal to the rear board judgment control module or the front board judgment control module and re-establish the communication connection. If the number of communication establishments equals the predetermined number for the second time, the communication status judgment module will transmit the abnormal communication status to the communication status monitoring module.

[0062] It is understandable that in this embodiment, establishing communication multiple times can reduce the probability of communication failure, while power restart can eliminate factors other than damage to the control module that could cause communication failure.

[0063] In this embodiment, both the communication status monitoring module and the communication status judgment module are obtained through a communication line connecting the front board judgment control module and the rear board judgment control module, and both the communication status monitoring module and the communication status judgment module are functions built into the front board judgment control module or the rear board judgment control module itself.

[0064] The rear panel judgment and control module includes a random data generation module, which is connected to a wireless communication module and is used to obtain random data based on the door opening command sent by the user's mobile phone.

[0065] The back panel judgment and control module includes a data decryption module, which is connected to the wireless communication module. The data decryption module is used to obtain the original password before encryption based on the encrypted data sent by the user's mobile phone.

[0066] The rear panel judgment control module includes a password verification module, which is connected to a wireless communication module. The password verification module is also connected to a random data generation module and a data decryption module, and is used to control whether the rear panel judgment control module executes the door opening command based on the comparison result of the original password and the random data.

[0067] Understandably, the user's mobile phone sends the door opening command to the wireless communication module, and at the same time, the random data generation module obtains random data and returns it to the user's mobile phone. The user's mobile phone then encrypts the random data according to the encryption module and transmits the encrypted data to the wireless communication module. The data decryption module obtains the original password before encryption based on the encrypted data sent by the user's mobile phone. The password verification module controls the back panel to determine whether the control module should execute the door opening command to the back door based on the comparison result between the original password and the random data.

[0068] The random data generation module, data decryption module, and password verification module are all built-in functions of the back-board judgment and control module.

[0069] In this embodiment, each smart lock has a unique communication password, and a random data generation module ensures that even with the same operation, the data exchanged each time will be different, thus preventing copying and cracking. Simultaneously, the key is stored only on the lock and on our company's server. Unlocking is achieved by transmitting the generated random number to the user's mobile phone; during this process, the key is not stored on the user's phone.

[0070] If the key on the door lock or the key on the server is lost unexpectedly, a new key can only be generated and used after both parties have agreed on the terms.

[0071] This embodiment improves the back-board main control logic based on the single master device control logic.

[0072] 1. The power supplies of the two systems are both independent and mutually controlled. When not in operation, each system enters a sleep state. Whichever system wakes up first can wake the other via a control line. If either the front board or the back board detects a communication anomaly with the other system, it will restart the other system via the control line.

[0073] 2. When communication between the front and rear boards is normal, the rear board acts as a slave unit in the entire lock system, making the operation of the lock simpler and smoother. When the rear board detects a communication failure with the front board, and restarting the other side still fails to restore normal communication, the rear board will activate a backup mode to achieve independent control (master mode). This way, even if the front board is damaged, the rear board can still control itself to complete basic door opening and closing actions. If someone is inside the door, they can directly open and close the door using the door open / close buttons without the front board's involvement. Furthermore, we have integrated a Bluetooth chip for human-machine interaction into the rear board. If someone is outside the door and encounters a damaged front board or a communication failure between the front and rear boards, they can use their mobile phone's Bluetooth to wirelessly communicate with the rear board and complete the door opening action.

[0074] 3. Two operating modes for the back panel of the door lock:

[0075] 1) Slave mode: When normal communication with the front panel is detected, the door lock rear panel automatically enters slave mode and transmits the collected peripheral data (Bluetooth data, rear panel button, rear panel touch button, etc.) directly to the front panel for processing.

[0076] 2) Host Mode: When an abnormality in communication with the front panel is detected, the back panel of the door lock will be switched to host mode, which will actively process peripheral data and take corresponding actions.

[0077] Those skilled in the art will understand that all or part of the steps in the methods of the above embodiments can be implemented by a program instructing related hardware. The program can be stored in a computer-readable storage medium, such as ROM / RAM, disk, optical disk, etc.

Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
