[0002] Although existing smart door locks provide security protection functions, they often lack effective information release and interaction methods. Traditional smart door locks often only provide passive display functions and lack the ability to actively interact with users. Some smart door locks have basic security alarm functions, such as anti-pry trial and error, but lack more advanced intelligent response functions. In addition, ordinary display screens have poor visibility in outdoor environments and high power consumption, which is not conducive to the long-term operation of door locks. Summary of the invention

[0003] The purpose of this invention is to solve the problem that existing smart door locks lack the ability to release information, and to propose a smart door lock system based on an ink screen for real-time information release.

[0008] Furthermore, the external acquisition module also includes a face recognition unit for capturing and identifying facial features of the user, and the face recognition unit is connected to the main control module via a UART serial port.

[0009] Furthermore, the smart door lock system also integrates a multifunctional information release module and adopts multiple information release methods.

BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a principle block diagram of the intelligent door lock system of the present invention. DETAILED DESCRIPTION

[0015] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] This embodiment provides a smart door lock system based on an ink screen for real-time information release. Its hardware composition and connection relationship are as follows: Figure 1 As shown, it includes an external acquisition module, a main control module, a communication module and an ink screen module.

[0017] The external acquisition module is used for key data authentication input or collecting user request update instructions, including a key unit, a fingerprint unit, a card reading unit and a face recognition unit.

[0018] The key unit includes a numeric keyboard and / or a touch-sensitive button for inputting a password or other user instructions. The key unit is physically connected to the main control module to ensure the stability and response speed of the operation. The user inputs through the numeric keyboard of the door lock, and the main control module monitors the keyboard input in real time, converts the user input information into a digital signal, and stores it in the memory of the main control module. The built-in keyboard processing program of the main control module compares the digital signal with the preset key value mapping relationship to determine the user's intention (for example: to execute password unlocking or to execute the door lock synchronization function).

[0019] The fingerprint unit (such as a capacitive fingerprint sensor) is located in the handle area of ​​the door lock and is integrated into the front panel of the door lock for fingerprint recognition when unlocking. When the user holds the door handle to unlock the door, fingerprint recognition can be conveniently performed. The fingerprint module is physically connected to the main control and communicates with the main control through an encryption protocol to ensure data security. When the user's finger touches the sensor surface of the key unit, the peaks (ridges) and troughs (groove lines) of the fingerprint will form tiny capacitance changes on the sensor. The capacitive sensor inside the sensor will detect these capacitance changes, convert these changes into electrical signals, and process these signals through internal algorithms. The processed electrical signals are converted into digital signals, and the main control receives the digital signals and stores them in the memory.

[0020] The card reading unit is connected to the main control module. When a user swipes a card through the card reader of the door lock, the main control module detects the approach of the card, and the card reader reads the card information. The read card information is processed by the internal algorithm of the main control module, and the card data is converted into a digital signal and stored in the memory of the main control module. The face recognition unit is located at the upper part of the front plate of the door lock, and is used to capture the user's facial features and identify them. The face recognition unit is connected to the main control module through the UART serial port to ensure fast data processing and response. The face recognition unit enhances the security of the door lock and provides a contactless unlocking method. The face recognition unit uses a camera to capture the user's facial image, and uses a live algorithm to ensure that the captured face is a live face. The feature algorithm is used to extract features, such as the shape and position of the eyes, nose, mouth and other parts, and the facial features are converted into digital signals and stored in the memory of the main control module.

[0021] The main control module is the core of the door lock front panel. It adopts a high-performance embedded MCU (such as STM32, ESP32, TelinkTLSR8258, etc.) and is connected to the external acquisition module and communication module through physical connections (such as cables or PCB traces). It is used to monitor the door lock status and user interaction, perform logical operations on various instructions and information, make decisions based on preset conditions or trigger events, and send update requests to the communication module.

[0022] The communication module supports a variety of physical connection methods, such as WIFI, cellular network, etc., and is connected to the main control module through a UART interface to ensure the real-time and reliability of data transmission. The communication module can communicate with a remote server to receive a request update instruction from the main control module, obtain the latest information data from the remote server according to the instruction, and parse and store the obtained information data in the main control module; The ink screen module is installed in the upper area of ​​the front plate of the door lock, and adopts a 3.1-inch monochrome display to provide a larger display area to display rich information content. The ink screen is designed to be embedded, and is protected by a layer of transparent acrylic plate on the outside and fixed by a mold on the inside to prevent damage and enhance durability. The ink screen module is connected to the communication module through the SPI interface, and is used to receive the display data of the communication module according to the update instruction of the main control module, and erase and / or update the display content of the ink screen.

[0023] The intelligent door lock system integrates a multifunctional information release module and adopts a variety of information release methods, which greatly improves the flexibility and real-time performance of information release. The information release methods include: Real-time response release, release update instructions in real time according to user instructions, and update the ink screen display content locally; Trigger release: Release update instructions based on specific information triggered by trigger events such as door lock opening, door lock closing, and alarm. For example, display a safety prompt when the door is not closed, which enhances the interactivity and security of the door lock. Remote control release: according to the remote control command sent by the communication module, the update command is released. Users can remotely update the display content through the web interface or mobile application. Whether it is changing the welcome message or issuing an emergency notice, it can be conveyed to visitors or family members instantly; Scheduled release, automatically release update instructions according to the set schedule, and automatically update display content according to the set schedule, such as door lock power, schedule reminders, etc., to improve the timeliness of information; Dynamic information release, based on the dynamic information obtained from the Internet, can automatically obtain the latest pictures, announcements and other information from the Internet, and transmit it to the main control module through the communication module. The main control module then issues update instructions to the ink screen module, which is displayed in real time on the ink screen, such as news summaries, community notifications, etc., to provide users with instant information.

[0024] The intelligent door lock system of the present invention adopts a multifunctional information release method, making the door lock display more diversified and intelligent, greatly improving the flexibility and real-time performance of information release. Each information release method is designed for specific usage scenarios and user needs, and can meet the information needs of different users in different scenarios.

[0025] The intelligent door lock system also includes an intelligent response module, which can make corresponding intelligent responses according to different triggering events, providing more intelligent security protection. The intelligent response module enables the door lock to actively provide services to users, rather than just passively responding to user operations, thereby improving the intelligence level of the door lock and user experience. The intelligent response includes security warnings, daily notifications and user behavior learning. The security warning is to immediately display warning information when an incorrect attempt to unlock or other security threats is detected, and notify the user through the communication module to improve the security of the door lock; the daily notification is to automatically update the displayed information according to time or user-defined rules, such as reminding users of important schedules or family activities; the user behavior learning adopts a user behavior learning algorithm to automatically adjust the security response threshold according to the user's unlocking habits and patterns to achieve personalized security protection. By analyzing the user's unlocking time, frequency and method, a behavioral baseline is established, abnormal behavior is identified, and the alarm sensitivity is adaptively adjusted, while allowing users to customize security settings to improve accuracy and reduce false alarms.

[0026] The software implementation and data processing of the smart door lock system of this embodiment include: 1. Main control module data analysis: 1. Data collection: Key data collection: The user inputs through the door lock's numeric keypad, the main control module monitors the keyboard input in real time, converts the user input information into a digital signal, and stores it in the memory. The built-in keyboard processing program of the main control module compares the digital signal with the preset key value mapping relationship to determine the user's intention (for example: executing a password to unlock or executing a door lock synchronization function).

[0027] Fingerprint data collection: When the user's finger touches the sensor surface of the fingerprint unit, the peaks (ridges) and troughs (grooves) of the fingerprint will form tiny capacitance changes on the sensor. The capacitance sensor inside the sensor will detect these capacitance changes, convert these changes into electrical signals, and process these signals through the internal algorithm of the fingerprint unit. The processed electrical signals are converted into digital signals. The main control module receives the digital signals and stores them in the memory.

[0028] Card data collection: The user reads the card through the card reader of the card unit. The main control module detects the approach of the card, and the card reader reads the card information. The read card information is processed by the internal algorithm of the main control module, and the card data is converted into a digital signal and stored in the memory.

[0029] Facial data collection: The facial recognition unit uses a camera to capture facial images, uses a live algorithm to ensure that the captured face is a live face, and uses a feature algorithm to extract features, such as the shape and position of the eyes, nose, mouth and other parts, converting facial features into digital signals and storing them in the memory of the main control module.

[0030] Communication data collection: When the main control module communicates with the communication module, it receives update instructions from the remote server and makes corresponding responses based on different instructions.

[0031] 2. Data reception and processing: (1) Input data processing: For the information (including key data and command information) input by the user through the external acquisition module, the intelligent door lock system stores the data in the memory of the main control module, then matches and authenticates the key data, calls the key verification interface, and verifies whether the key is valid. If valid, it returns TRUE, otherwise it returns FALSE; For the message input by the remote server through the communication module, the main control module parses the data packet and command number, verifies the validity of the message, and after the validity verification is passed, jumps to different function menus according to different command numbers.

[0032] (2) Data storage: For the information input by the user through the external acquisition module, the smart door lock system stores the data in the memory of the main control module for subsequent authentication and analysis; For the remote server information synchronized by the communication module, the main control module parses the data packet and command number, and then verifies the validity of the information. After the validity verification is passed, it extracts specific information (such as key information, door lock configuration, etc.) to erase or modify the Flash data.

[0033] (3) Data matching and authentication: For the key data input by the user through the external acquisition module, after it is saved in the memory, the key data is matched and authenticated, and the key verification interface is called to verify whether the key is valid. If it is valid, TRUE is returned, and if it is invalid, FALSE is returned; For the data synchronized by the communication module, the validity of the data is first checked. If the validity verification passes, the corresponding instruction status code is returned. If the verification fails, FALSE is returned.

[0034] (4) Event generation and response: Event generation: The smart door lock system generates events based on preset trigger conditions or real-time monitored data. For example, when it detects that the door is not closed correctly, it generates an "unclosed door event"; when the user tries to unlock the door with a fingerprint or password, it generates an "unlock event"; Event recognition: The event recognition logic built into the main control module can recognize and distinguish predefined events, such as "door open event", "lock open event", "low battery alarm event", etc. Response trigger: Once a specific event is generated, the intelligent response module will trigger a corresponding intelligent response based on the event type. For example, if the "door is not closed" event is generated, a security warning will be triggered and a prompt "Please close the door" will be displayed on the ink screen.

[0035] 3. Data transmission: The main control module sends the processed data frame to the communication module through the serial port (UART) or other asynchronous communication interface. The data frame contains the start bit, data bit, check bit and stop bit to ensure the integrity and correctness of the data during the transmission process. The main control module uses DMA (direct memory access) to improve the efficiency of data transmission and reduce the CPU load.

[0036] 4. Communication protocol: The main control module and the communication module use a pre-defined communication protocol to exchange data. The protocol defines the structure of the data packet, command set, response mechanism and error handling process. Before the data is sent, the main control module packages the data according to the protocol, including adding header information and verification.

[0037] 5. Power Management: The main control module monitors the power status, including battery power and charging status, to ensure stable system operation. When the power is insufficient, it prolongs battery life by reducing the refresh rate or entering low power mode.

[0038] 6. User Interaction: The main control module responds to user input events, such as key operations and touch input, through the interrupt service routine (ISR). The user interaction data is converted into event messages and processed by the task scheduler of the main control module. For example, when the user enters the wrong password continuously, the ink screen is automatically triggered to update the display information.

[0039] 7. Exception handling: The main control module implements error detection and exception handling mechanisms, such as timeout retransmission, resend strategy and error logging. When an exception is detected, the main control module can take corresponding recovery measures, such as resetting the communication module or restarting the system.

[0040] 2. Communication module data analysis: 1. Communication protocol configuration: The protocol type for communicating with the main control module is UART (Universal Asynchronous Receiver / Transmitter); the protocol type for communicating with the ink screen module is SPI (Serial Peripheral Interface); and the protocol type for communicating with the remote server is HTTP (Hypertext Transfer Protocol). During HTTP communication, each communication is completed through an independent request and response process. In an environment with good network bandwidth, the simplicity and wide support of HTTP make it easy to integrate into the existing Web infrastructure.

[0041] 2. Data transmission method: Data transmission with the main control module: The communication module is connected to the physical serial port of the main control module, following the data frame structure of the UART protocol and asynchronous transmission; Data transmission with the e-ink display module: The communication module is physically connected to the e-ink display module via SPI, following the data frame structure of the SPI protocol, and selecting full-duplex or half-duplex based on real-time performance requirements; Data transmission with remote server: The communication module communicates with the remote server through a wireless network (such as Wi-Fi, cellular network, etc.) and uses the HTTP protocol for data exchange.

[0042] 3. Data processing and analysis: Data interaction with the main control module: After the communication module receives the data sent by the main control module (including user verification information, door lock status update, etc.), it performs format verification and error detection to ensure the integrity and correctness of the data. For user verification information, the communication module forwards it to the remote server for further processing. For door lock status updates, the communication module stores them locally and sends them to the IoT platform when needed.

[0043] Data interaction with the ink screen module: The communication module receives new display content, such as text, images, etc. from the IoT platform. The communication module converts these contents into a format suitable for ink screen display and sends them to the ink screen module according to the SPI protocol. After receiving the data, the ink screen module updates the display content according to the instructions.

[0044] Data interaction with the IoT platform: The communication module periodically sends door lock status update requests to the remote server to obtain the latest control instructions or information updates. When receiving the HTTP response from the remote server, the communication module first decodes the received data and extracts the payload. The communication module performs corresponding operations based on the parsed message content, such as updating the ink screen display content, synchronizing the status, or adjusting the system settings.

[0045] Remote update processing: The communication module communicates with the remote server through the HTTP protocol, receives update instructions from the remote server, and the received update data is processed and used to update the ink screen display content.

[0046] 5. Local update processing: The communication module reads data from the built-in Flash storage. The local storage contains preset update information, such as advertisements, notifications, etc. According to user settings or scheduled tasks, the communication module performs local updates.

[0047] 6. Error handling: If an error is detected during the reception or parsing process, the communication module will execute the error handling strategy, including retransmitting the request, sending an error report to the remote server, or notifying the main control module.

[0048] 3. Information Release: 1. Scheduled release: The system is equipped with a real-time clock (RTC) to track time. When the door lock is powered, the RTC can keep the time updated regardless of whether the door lock is connected to the network. The main control module stores the last ink screen update time and has a scheduled task. When the preset time point is reached, the ink screen time is automatically updated and the following operations are automatically performed: (1) Wake up the network: start the communication module to establish a connection with the remote server; (2) Synchronize time: obtain accurate network time from the remote server and update its internal clock; (3) Request update: Send an update request to the communication module to trigger the remote server to send the latest information data; (4) Content update: After receiving the data, the communication module transmits it to the ink screen module to update the display content of the ink screen.

[0049] 2. Trigger release: (1) Event recognition: The event recognition algorithm in the system firmware can accurately identify and distinguish predefined events, such as successful unlocking, open warning, incorrect unlocking attempt, low battery alarm, etc. These events are identified through sensor data and status monitoring in the main control module.

[0050] (2) Event processing logic: For each predefined event, the main control module has corresponding processing logic. For example, when it is detected that the door is not closed correctly, the safety warning unit of the intelligent response system will be triggered and a prompt message will be displayed on the ink screen.

[0051] (3) Real-time detection and response: The main control module monitors the door lock status and user operations in real time through interrupts. Once a specific event is identified, it immediately executes the preset response measures, such as updating the display content, sending notifications, etc. These response measures can be implemented through event processing functions. For example, by calling the displayMessage function to update the display content of the ink screen.

[0052] (4) Content update: Based on the type of triggering event, the main control module makes a decision to update the content displayed on the e-ink screen. The updated content includes safety tips, operating instructions, status information, etc., to ensure that users can obtain relevant information in a timely manner. This usually involves reading the preset prompt information from the memory of the main control module and sending it to the e-ink screen module for display.

[0053] (5) Remote publishing and notification: When a specific event is triggered, not only can the local display content be updated, but the user can also be remotely notified or remote control commands can be executed through the communication module. This is done through the network communication protocol HTTP that communicates with the remote server, including the sending and receiving of HTTP requests.

[0054] (6) Event logging and auditing: Record all triggered events and corresponding processing results, including timestamp, event type, processing measures, etc. These records can be used for subsequent auditing and analysis.

[0055] (7) User-defined events: Users customize events and corresponding response actions through mobile applications or web interfaces, providing greater flexibility and personalized experience. This usually involves the design of the user interface, allowing users to set specific trigger conditions and response actions, and sending these settings to the main control module for storage and execution.

[0056] 4. E-ink display update, such as Figure 1 As shown, the following steps are included: (1) Request update: The main control module sends an update request to the communication module; (2) Data analysis: The communication module receives the update request from the main control module and analyzes the data according to the protocol format to determine whether it is an online update or a local update. Online update processing: The communication module communicates with the remote server through the HTTP protocol and receives the processed display data sent by the remote server. These data, including text and images, have been converted into a format suitable for ink screen display on the remote server; Local update processing: The communication module directly reads the pre-stored display data from the main control module memory. This data has also been pre-processed and does not require additional analysis on the door lock side. (4) E-ink screen update: After the display data conversion is completed, it is transmitted to the driving circuit of the e-ink screen module to display the updated content.

[0057] Among them, remote server processing includes: Text data processing: The remote server first converts the received text data into an encoding format supported by the door lock system (such as UTF-8), then parses each Unicode character according to the UTF-8 encoding rules, looks up the corresponding encoding table (such as the GBK encoding table), maps the Unicode characters to the corresponding encoding, and finally converts the encoding into the bitmap or dot matrix data of the corresponding character so that the ink screen can display it directly.

[0058] Image data processing: The image file is processed by the BMP image data processing algorithm, the image file header and information header are checked, the file type and bit depth are confirmed, the image data is processed according to the bit depth, and converted into a grayscale image format suitable for ink screen display. The processed image data is encoded into a format suitable for the ink screen and then sent to the ink screen module for display.

[0059] 5. Intelligent response: The core of intelligent response is a set of efficient event recognition algorithms that can distinguish and identify a variety of different events, including but not limited to: Door lock prying: By analyzing the data collected from sensors such as anti-tamper switches, attempts to pry the door lock can be detected; Multiple incorrect password input: Record the user's password input behavior. If the user inputs incorrect passwords multiple times in a row, this will be considered a potential security threat. Abnormal access: By analyzing the time and frequency of user unlocking, normal usage patterns are learned, and behaviors that deviate from these patterns will be marked as abnormal; User behavior learning includes: Habit learning: Record the time, frequency and unlocking method of the user, and learn the user's normal usage pattern through algorithm analysis; Pattern recognition: Once a user's normal patterns are learned, behaviors that differ significantly from those patterns can be identified, allowing for more accurate identification of potential security threats. Adaptive adjustment: Adaptively adjust its response thresholds and strategies based on learned user behavior patterns to reduce false alarms and improve the efficiency of security protection.

[0060] The implementation steps of user behavior learning include: (1) Data collection and preprocessing: Various sensors (such as touch sensors, pressure sensors, image recognition modules, etc.) are used to collect user usage data in real time. The collected data may include the user's unlocking time, frequency, unlocking method used, etc. These data will be used for subsequent behavior analysis and pattern recognition; (2) Model training and compression: Use statistical analysis methods to perform preliminary processing on the collected data to identify normal usage patterns and potential abnormal behaviors. Utilize machine learning algorithms, such as cluster analysis, decision trees, or neural networks, to learn the user's behavior patterns and establish a behavior feature model. The behavior analysis results will be used to establish a user behavior baseline, which will serve as a reference for determining whether future behavior is abnormal.

[0061] (3) Event Detection: Based on preset security rules and learned user behavior patterns, pattern matching and anomaly detection algorithms are used to detect potential security events. The event detection module monitors sensor data and user behavior in real time. Once a behavior that deviates significantly from the normal pattern is detected, a security event is triggered. The detected events will be classified and marked according to the preset priority to facilitate subsequent decision making.

[0062] (4) Decision making: The intelligent response system automatically formulates a response strategy based on the type and severity of the detected event. The response strategy must take into account the urgency of the event, potential risks, and user-defined security preferences to determine the most appropriate response measures. Complex logical judgments may also be required. For example, if multiple incorrect password entries are detected, the system may first send a warning. If the password continues to be entered incorrectly, the door will be locked.

[0063] (5) Response execution: The intelligent response system executes response measures according to the established response strategy, including but not limited to triggering local alarms, sending remote notifications, automatically alarming or locking door locks. The intelligent response system is responsible for activating corresponding hardware devices, such as buzzers, door lock panels, motor locks, etc., to implement response measures, and records the details of response execution, including response type, timestamp and duration, to facilitate subsequent audits and feedback learning.

[0064] (6) Feedback learning: Based on the event handling results and user feedback, the learning algorithm and response strategy are further adjusted. By analyzing the effectiveness of event handling and user satisfaction with the response measures, the behavior analysis model and decision logic can be optimized. Feedback learning also helps update the user behavior baseline to adapt to changes in user behavior and new security threats.

[0065] The intelligent door lock system of the present invention greatly improves the flexibility and real-time performance of information release by integrating a multifunctional information release mechanism, which includes multiple modes such as timed release, event-triggered release, remote control release and dynamic information acquisition, each of which is designed for specific usage scenarios and user needs. It also has an intelligent response function, which can respond accordingly to different triggering events, providing more intelligent security protection, so that the door lock can actively provide services to users, rather than just passively responding to user operations, thereby improving the intelligence level of the door lock and user experience.

[0066] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. A person skilled in the art should understand that the technical solutions described in the above embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the present invention.
