Technical Field
[0001] This invention relates to an intelligent door lock management system, specifically an intelligent door lock management system based on 3D visualization and Internet of Things technology, belonging to the field of intelligent security technology. Background Technology
[0002] With the increasing demand for intelligent security, intelligent door lock management systems are playing an increasingly important role in modern building and property management. Existing intelligent door lock management systems typically rely on traditional methods such as password input, fingerprint recognition, or card unlocking. Taking the system with patent publication number CN107341885A as an example, it mainly consists of a door lock device, a mobile terminal, and a cloud platform. Data interaction between the door lock and the cloud platform is achieved through a communication module, and user operations are completed via the mobile terminal. However, existing technologies have many shortcomings that urgently need improvement. First, the identification methods are limited and lack security. Traditional door locks rely heavily on passwords, fingerprints, or cards, making them vulnerable to security threats such as password leaks, fingerprint duplication, or card loss. Second, existing systems lack the ability to intelligently identify abnormal behavior, making it difficult to proactively detect and prevent potential security risks such as tailgating and brute-force attacks, resulting in weak early warning capabilities. Furthermore, administrators must perform cumbersome procedures through an application when authorizing visitors or monitoring their status, leading to poor convenience. At the same time, most intelligent door lock systems lack an intuitive visual management interface, making it difficult for administrators to quickly and comprehensively grasp the door lock status and personnel access, hindering centralized management and efficient decision-making. To address the aforementioned issues, this invention proposes an intelligent door lock management system based on 3D visualization and Internet of Things (IoT) technologies. The system aims to comprehensively improve security, convenience, and management efficiency by integrating multimodal recognition technology, real-time data interaction mechanisms, and an innovative 3D visualization platform, thereby solving key challenges in existing technologies. Summary of the Invention
[0003] To address the shortcomings of existing smart lock management systems in terms of security, convenience, management efficiency, and monitoring and early warning capabilities, this paper proposes a smart lock management system based on 3D visualization and Internet of Things (IoT) technologies. This system provides an efficient, secure, and convenient smart lock management solution by integrating multimodal recognition technology, real-time IoT data interaction and processing, innovative applications of a 3D visualization platform, and intelligent abnormal behavior analysis and early warning mechanisms.
[0004] The objective of this invention can be achieved through the following technical solutions: A smart door lock management system based on 3D visualization and Internet of Things (IoT) technologies includes a smart door lock terminal, an IoT communication module, a 3D visualization platform, and a cloud server. Among them: The smart lock terminal is installed on the door and is responsible for collecting unlocking information and performing unlocking operations. The IoT communication module enables data transmission between the smart lock terminal and the cloud server; The 3D visualization platform runs on user terminal devices and is used to display and interact with door lock-related data; The cloud server stores and processes system data and interacts with other external systems.
[0005] Furthermore, the smart lock terminal uses a high-performance microcontroller as its core processor, integrating multiple sensors and recognition modules. Among them, the fingerprint recognition module collects the user's fingerprint information; the password input module supports user input of unlocking passwords; the card swipe recognition module supports IC card or NFC card unlocking; the 3D face recognition module uses 3D structured light or TOF technology to accurately capture three-dimensional facial features, achieving an accuracy rate higher than 99.8%, effectively resisting forgery attacks such as photos and videos, and is suitable for complex environments such as backlight and low light; the door magnetic sensor monitors the door's open / closed status in real time; and the anti-pry sensor detects abnormal situations such as forced entry, triggering an alarm and notifying the user.
[0006] Furthermore, the IoT communication module enables bidirectional data transmission between the smart lock terminal and the cloud server via wireless communication protocols such as Wi-Fi, Bluetooth, and Zigbee. Specifically, S1: The unlocking records, lock status, and abnormal alarm information collected by the smart lock terminal are encrypted and transmitted to the cloud server; S2: The module receives remote unlocking commands and permission update commands sent by the cloud server and executes the corresponding operations. The encryption process uses the AES-256 encryption algorithm to ensure the security of data transmission.
[0007] Furthermore, the 3D visualization platform, based on advanced 3D modeling technology, provides users with an intuitive 3D scene display of buildings and door locks.

[0009] Specifically, the key technical points of this invention include the following four aspects: A smart door lock terminal integrating multimodal recognition technology. This smart door lock terminal integrates a 3D face recognition module with traditional recognition methods (fingerprint, password, card swipe), significantly improving the accuracy and security of identity verification. The 3D face recognition module uses 3D structured light or Time-of-Flight (TOF) technology, emitting light of a specific wavelength and receiving reflected signals to construct a three-dimensional facial model, achieving high-precision identity authentication. This module, combined with traditional recognition methods, forms a multi-layered security protection system, ensuring the reliability of the door lock's first line of defense.
[0010] Real-time data interaction and processing based on the Internet of Things (IoT). The IoT communication module enables real-time, stable, and secure data transmission between the smart lock terminal and the cloud server via wireless communication protocols such as Wi-Fi, Bluetooth, and Zigbee. Specifically, the smart lock terminal encrypts and transmits collected data such as unlocking records, lock status, and abnormal alarm information to the cloud server through the communication module; the cloud server, in turn, sends remote unlocking commands and permission update commands to the smart lock terminal through the communication module and updates the lock status in real time. This real-time data interaction and processing mechanism breaks through the time and space limitations of traditional locks and is a core technology for achieving intelligent management.
[0011] Innovative Application of a 3D Visualization Platform. This 3D visualization platform utilizes advanced 3D modeling technology to present users with a three-dimensional scene of buildings and door locks. Specifically, the platform uses 3D modeling software to digitally model buildings and embeds information such as the location and status of door locks into the model. Users can intuitively view the location and status of door locks through the platform, and click on the door lock icon to obtain detailed information. Furthermore, the platform supports a virtual roaming function, allowing users to browse the three-dimensional scene from a first-person perspective and quickly locate the target door lock. This innovative integration of 3D visualization technology with a door lock management system provides users and administrators with a completely new operating experience, which is a key differentiating feature of this invention compared to existing technologies.
[0012] Intelligent Abnormal Behavior Analysis and Early Warning. The cloud server, based on big data analytics, deeply mines and analyzes the large amount of unlocking data and status information uploaded by the smart lock terminal. Specifically, S1: Through a preset algorithm model, it analyzes data such as unlocking frequency, unlocking time, and number of unlocking failures to determine if abnormal behavior exists; S2: When abnormal behavior is detected, the system automatically issues an early warning message and notifies the user and administrator via SMS or push notification. This intelligent abnormal behavior analysis and early warning mechanism enhances the system's ability to proactively prevent security threats and is an important technical means of security management in this invention. The beneficial effects of this invention are as follows: by integrating multimodal recognition technology, the accuracy and reliability of identity authentication are significantly improved, effectively preventing unauthorized intrusion; real-time data interaction between the smart lock terminal and the cloud server is achieved through an IoT communication module, breaking the time and space limitations of traditional locks; a 3D visualization platform provides users with an intuitive operating interface, greatly improving ease of use; and an intelligent abnormal behavior analysis and early warning mechanism detects potential security risks in advance and issues timely warning information.

[0013] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.
[0014] Figure 1 This is a system architecture diagram of the present invention.
[0015] Figure 2 This is a schematic diagram of the 3D visualization interface of the present invention. Detailed Implementation
[0016] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0017] Please see Figure 1-2 As shown, a smart door lock management system based on 3D visualization and Internet of Things (IoT) technology is presented. The system architecture consists of a smart door lock terminal, an IoT communication module, a cloud server, and a 3D visualization platform. The specific functions and operation of each component will be described in detail below.
[0018] The smart lock terminal is the core device of the entire system, installed on the door of the building, used to collect unlocking information and execute unlocking operations. The smart lock terminal integrates a lock body control module and an information acquisition module. The lock body control module is responsible for receiving commands and controlling the opening and closing of the lock, while the information acquisition module completes identity authentication and status monitoring tasks through various sensors and recognition modules. The fingerprint recognition module collects the user's fingerprint information through optical or capacitive sensors and transmits it to the core processor for matching and verification; the password input module allows users to enter preset passwords via a keyboard, and the password data is encrypted and stored locally or uploaded to a cloud server; the card swipe recognition module is compatible with IC cards and NFC cards, completing identity verification by reading the unique identifier in the card; the 3D face recognition module uses 3D structured light or TOF technology, constructing a three-dimensional face model by emitting light of a specific wavelength and receiving reflected signals, ensuring high-precision identity authentication even in complex environments such as backlight and low light. The door magnetic sensor monitors the door's open / closed status in real time. When it detects that the door is open or closed, it immediately sends the status information to the core processor. The anti-pry sensor is used to detect forced lock picking. Once an alarm is triggered, the system will immediately notify the administrator and upload the abnormal information to the cloud server through the IoT communication module.
[0019] The IoT communication module enables bidirectional data transmission between the smart lock terminal and the cloud server via Wi-Fi, Bluetooth, Zigbee, or NB-IoT communication protocols. Specifically, the IoT communication module first encrypts data collected by the smart lock terminal, such as unlocking records, lock status, and abnormal alarm information, using the AES-256 encryption algorithm, and then transmits it to the cloud server via the wireless network. Upon receiving the data, the cloud server decrypts it and stores it in the data storage module. Simultaneously, based on the data analysis results, it generates corresponding control commands, such as remote unlocking commands or permission update commands, and sends them to the smart lock terminal through the IoT communication module. This real-time data interaction mechanism ensures timely updates of lock status information and efficient implementation of remote control functions.
[0020] As the central hub of the system, the cloud server has powerful data storage and processing capabilities. It internally includes a user / permission management module, an API interface, and a data storage module. The user / permission management module is responsible for managing operations such as user registration, login, and permission allocation, supporting administrators to add or delete user permissions through a 3D visualization platform and set temporary visitor permissions. The API interface is used for data interaction with other external systems (such as property management systems and security monitoring systems) to achieve function expansion. For example, when the system detects an abnormal unlocking behavior, it can send an alarm message to the security monitoring system through the API interface to trigger a linkage response. The data storage module is used to store the unlocking records, door lock status information, and abnormal alarm data uploaded by the intelligent door lock terminal, providing support for subsequent data analysis and report generation.
[0021] The 3D visualization platform runs on computer, tablet, or mobile terminal devices, providing users with an intuitive three-dimensional display of buildings and door locks by calling the data in the cloud server. Based on advanced 3D modeling technology, the platform uses the comprehensive overview module to digitally model the building and embed information such as the location and status of each door into the three-dimensional building model. Users can browse the three-dimensional scene from a first-person perspective through the virtual roaming function to quickly locate the target door lock position. After clicking on the door lock icon, the platform will display the detailed information of the door lock, including the latest unlocking records and current authorized users. In addition, the 3D visualization platform also includes an alarm information module and a data statistics and analysis module. The alarm information module real-time displays the abnormal behaviors detected by the system, such as multiple failed attempts to unlock or abnormal unlocking frequencies, and notifies the administrator through text messages or push notifications; the data statistics and analysis module generates detailed unlocking record reports based on historical data to help administrators optimize management strategies.
[0022] The operating principle of this system is as follows: After the user completes identity authentication through the fingerprint recognition module, password input module, card swiping recognition module, or 3D face recognition module, the intelligent door lock terminal uploads the authentication result to the cloud server for secondary verification. After verification, the cloud server sends an unlocking instruction to the intelligent door lock terminal, and the lock body control module executes the unlocking operation and feeds back the status information to the cloud server. During this process, the door magnetic sensor continuously monitors the opening and closing status of the door, and the anti-pry sensor detects whether there is a violent pry lock behavior. If an abnormal situation is detected, the system will immediately trigger an alarm and upload the abnormal information to the cloud server through the Internet of Things communication module. The cloud server performs real-time analysis on the received data to determine whether there is an abnormal behavior. For example, when a certain door has multiple failed attempts to unlock within a short period of time, the system will send a warning message through the alarm information module and notify the administrator to take corresponding measures.
[0023] To further enhance the system's intelligence, the cloud server also incorporates big data analytics. By deeply mining and analyzing the vast amounts of unlocking data and status information uploaded by the smart lock terminals, the system can identify potential security vulnerabilities. For example, by analyzing unlocking frequency and time distribution, the system can detect abnormal usage patterns, such as frequent unlocking late at night or unusual access outside of working hours. These analytical results not only help administrators optimize lock management strategies but also provide decision support for property management.
[0024] In practical applications, this system can be widely used in residential communities, office buildings, hotels, and other locations. Taking residential communities as an example, administrators can intuitively view the door lock status of each building through the 3D visualization platform and quickly locate any anomalies requiring attention. For instance, when a resident reports a door lock malfunction, the administrator can quickly locate the resident's floor using the virtual roaming function and remotely issue a repair order through the platform. For visitor management, administrators can set temporary visitor permissions on the platform; visitors can complete identity authentication and enter designated areas by scanning a QR code using a mobile app. This convenient operation significantly improves the user experience while also reducing management costs.
[0025] In summary, this invention achieves a comprehensive upgrade of the intelligent door lock management system by integrating multimodal recognition technology, real-time data interaction and processing via the Internet of Things (IoT), innovative applications of a 3D visualization platform, and an intelligent abnormal behavior analysis and early warning mechanism. The system not only improves the accuracy and security of identity authentication but also enables remote management and real-time monitoring through IoT communication modules and cloud servers. The 3D visualization platform provides users and administrators with an intuitive interface, significantly enhancing ease of use. The intelligent abnormal behavior analysis and early warning mechanism uses big data analytics to proactively identify potential security risks, providing strong support for proactively preventing security threats. The implementation of the above technical solutions gives this invention significant advantages in security, convenience, management efficiency, and monitoring and early warning capabilities, solving many problems existing in the prior art and possessing significant technical value and application prospects.
