Description

Technical Field

[0001] This application relates to the field of intelligent security, and more specifically, to an optical communication access control system, method, device, and readable storage medium. Background Technology

[0002] In the current security product software market, communication between controllers and gate control units generally relies on traditional wired transmission methods, primarily including network cables (usually via TCP protocol) and the RS-485 bus. These two methods offer certain advantages in terms of stability and reliability, especially in the accuracy of data transmission. However, they also introduce significant limitations.

[0003] The shortcomings of existing security product software are mainly reflected in the following aspects:

[0004] 1. Limited transmission distance: Both TCP-based wired transmission and RS-485 bus transmission have limited transmission distances. This is particularly evident in large building complexes or wide-area security networks, limiting the system's coverage and application scenarios.

[0005] 2. High wiring complexity: The current technology uses a one-to-many wiring mode, which means that one or more additional lines are needed for each additional gate control unit. This not only increases the complexity and cost of construction, but also increases the difficulty of system maintenance and troubleshooting.

[0006] 3. Poor scalability: Most security product software controllers are designed to support a fixed number of door control units, such as 4 doors or 8 doors. This design limits the system's scalability. When more door control units are needed, the controller often needs to be replaced, increasing user costs and inconvenience.

[0007] 4. Slow Business Linkage Response Speed: Due to the data volume limitations of the controller, business linkage between doors usually requires data processing and coordination through the backend server. While this centralized processing mode simplifies the controller design, it leads to a decrease in the speed of business linkage response, which may affect the timeliness and effectiveness of emergency response in emergency situations.

[0008] Based on this, this application provides an optical communication access control scheme to overcome the aforementioned defects of the prior art to a certain extent. Summary of the Invention

[0037] As can be seen from the above technical solutions, the optical communication access control system, method, device, and readable storage medium provided in this application firstly solves the problem of short data transmission distance and complex wiring between the controller and the access control unit by introducing an optical distribution network as the data transmission medium.

By precisely controlling the behavior of each gating unit, the service linkage response speed and operational efficiency are improved. Attached Figure Description

[0047] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0048] The following section introduces the solution proposed in this application. The technical solution is as follows, and details are provided below.

[0049] Figure 1 This is a schematic diagram of the structure of an optical communication access control system disclosed in an embodiment of this application.

[0050] Figure 2 This is a data transmission diagram of an optical communication access control system disclosed in an embodiment of this application.

[0051] like Figure 1 and Figure 2 As shown in the figure, this application provides an optical communication access control system, including an access controller, an optical distribution network, and a door control unit;

[0052] The access control controller consists of a core board and an optical line terminal, and the door control unit consists of a door control logic unit and an optical network terminal.

[0053] The access control controller transmits data with each of the control units through the optical distribution network;

[0054] The optical distribution network converts the single optical fiber connected to the access controller into multiple powered optical fibers that are connected to each of the control units to achieve data multiplexing.

[0055] The optical network terminal transmits data to the gate control logic unit after photoelectric conversion.

[0056] Specifically, the optical communication access control system of this application consists of a self-developed access controller, an optical distribution network, and door control units. By integrating the optical distribution network as the core data transmission network, the problem of short data transmission distance and complex wiring between the controller and door control units in traditional access control systems is successfully solved. Traditional access control systems often suffer from signal attenuation, complex wiring, and limited transmission distance, leading to degraded system performance and increased maintenance costs. The introduction of the optical distribution network, with its unique topology and fiber optic transmission technology, not only simplifies the system architecture but also significantly improves the efficiency and stability of data transmission.

[0057] Optical communication, with its unique advantages such as high bandwidth, long-distance transmission, and low attenuation, enables efficient and stable data transmission between access control controllers and various access control units. Optical communication has strong anti-interference capabilities, effectively resisting interference from external environmental factors such as electromagnetic interference and lightning strikes, ensuring the stability and security of the access control system. Even in harsh weather conditions or areas with complex electromagnetic environments, optical communication access control systems can maintain stable communication quality, providing reliable technical support for access control management. Simultaneously, optical fiber, as the medium for data transmission, can carry massive data flows, ensuring high-speed, latency-free data transmission between the access control controller and various distributed access control units. This efficient transmission mechanism allows the system to easily handle the access control management needs of large-scale and complex scenarios, such as large office buildings, schools, hospitals, and industrial parks.

[0058] Secondly, this application achieves flexible support for the number of access control units by the controller. Through the data multiplexing function of the optical distribution network, the controller can connect to any number of access control units as needed without changing its hardware or software configuration. This feature not only solves the problem of needing to define multiple controller models due to different numbers of supported access control units, reducing development and maintenance costs, but also enables the system to easily cope with application scenarios of different scales, improving the system's adaptability and scalability. The flexibility and scalability of the optical distribution network also facilitate the future upgrade and expansion of the access control system. Through simple fiber optic connections and configuration, the system can easily achieve the access of new access control units without large-scale modifications to the original network structure, reducing upgrade costs and maintenance difficulty. The optical distribution network also supports multiple data transmission protocols and interface standards, enabling the system to seamlessly integrate with other security systems, building management systems, etc., to achieve more comprehensive intelligent management.

[0059] Furthermore, optical distribution networks convert a single passive fiber optic line into multiple powered fiber optic cables, simplifying the cabling structure and reducing construction difficulty and cost. Specifically, optical distribution networks can convert a single, non-functional fiber optic line into multiple fiber optic cables with independent power supply and data transmission capabilities, simplifying the cabling structure and thus significantly reducing construction difficulty and cost.

[0060] Furthermore, this application supports complex internal linkage logic, such as anti-submarine warfare and interlocking. The implementation of these logics benefits from the high-speed transmission capability of optical communication and the flexible configuration of the system. By precisely controlling the behavior of each gate control unit, the system can improve response speed and operating efficiency while ensuring security, providing users with a more convenient and secure access control experience.

[0061] Furthermore, the core board and the optical line terminal, as well as the gate control logic unit and the optical network terminal, all use Netty communication.

[0062] Specifically, in the optical communication access control system, to ensure the efficiency, real-time performance, and stability of data transmission, Netty communication is used as the communication bridge between the core board and the optical line terminal, and between the door control logic unit and the optical network terminal. Netty, as a high-performance, asynchronous event-driven network application framework, possesses powerful I / O processing capabilities, non-blocking characteristics, and flexible scalability, providing strong support for data transmission in the access control system. Through Netty communication, not only is fast and accurate data transmission between the core board and the optical line terminal, and between the door control logic unit and the optical network terminal, is achieved, but the stability and reliability of the system when facing large-scale concurrent requests are also ensured, providing a solid technical guarantee for access control management.

[0063] Furthermore, one optical fiber is a passive optical fiber, and the multiple optical fibers are powered POF optical fibers.

[0064] Specifically, when POF fiber optic cables are connected to the gate control unit, the optical network terminal performs photoelectric conversion, transmits the data to the gate control unit for business logic interaction, and provides power to the gate control unit. Multiple fiber optic cables utilize powered POF fibers, which can undertake specific data transmission tasks and provide stable power support to the remote gate control unit. This integrated design of data transmission and power supply not only greatly simplifies the wiring structure of the access control system but also significantly reduces the complexity and difficulty of the construction process, thereby effectively saving construction costs and time.

[0065] In summary, the optical communication access control system of this application overcomes, to some extent, the shortcomings of existing technologies in terms of data transmission distance, wiring complexity, and controller model diversity. Furthermore, by supporting flexible access control unit integration and complex internal linkage logic, it also improves the system's adaptability and security.

[0066] This application also provides an optical communication access control method, which can be applied to the access controller mentioned above, and the executing entity can be a computer terminal or the processor or server of a smart terminal.

[0067] The following section introduces the solution proposed in this application. The technical solution is as follows, and details are provided below.

[0068] Figure 3 This is a flowchart of an optical communication access control method disclosed in an embodiment of this application.

[0069] Figure 4This is a data interaction diagram of an optical communication access control system disclosed in an embodiment of this application.

[0070] like Figure 3 and Figure 4 As shown, the method may include:

[0071] Step S1: Receive the basic parameters sent by the software platform after the access controller is successfully registered.

[0072] Specifically, during the deployment and configuration of the access control system, once the access controller successfully registers with the software platform via the RJ45 network port, it signifies that the access controller has officially joined the entire access control management network. Subsequently, the software platform will perform operations including adding necessary configuration information to the newly registered controller and sending basic parameters to the access controller. Basic parameters may include, but are not limited to, the access controller's unique identifier, network configuration (such as IP address, subnet mask, etc.), time synchronization settings, access control permission allocation, alarm thresholds, and communication protocols with other system components.

[0073] Step S2: Obtain the registration information and instruction ID pushed by the gate control unit after its first network connection.

[0074] Specifically, after the access control unit connects to the network for the first time and successfully establishes a communication connection, it pushes its registration information and corresponding command ID to the access control system. The registration information typically includes key information such as the access control unit's unique identifier (e.g., serial number, MAC address), device type, firmware version, and current status. This information is crucial for system configuration, monitoring, and troubleshooting. Simultaneously, the access control unit generates one or more command IDs, which are unique identifiers used by the system to remotely control the access control unit, query its status, or execute specific tasks. By acquiring this registration information and command IDs, the access control management system can establish an effective communication link with the access control unit, enabling remote monitoring and management of the access control unit and ensuring the overall security and stability of the access control system.

[0075] Step S3: Based on the registration information, perform allocation initialization detection, allocate IPs to each of the gating units and return the basic parameters, so that each of the gating units can filter out the corresponding instructions according to the instruction ID, parse and execute the corresponding operations.

[0076] Specifically, the process of performing allocation initialization detection based on the registration information, allocating IPs to each of the gating units, and returning the basic parameters may include:

[0077] ①Based on the registration information, analyze and verify that each gate control unit is legal and has not been registered repeatedly;

[0078] ② Assign a unique IP address to each of the gate control units according to the network plan;

[0079] ③ Based on the type and functional requirements of each gate control unit, return the corresponding basic parameters.

[0080] The allocation and initialization checks based on the registration information pushed after the gated unit's initial network connection are to ensure that each gated unit can be correctly identified, its legitimacy verified, and duplicate registrations avoided. Simultaneously, resource allocation is performed according to the system's network plan and the specific needs of each gated unit. Specifically, the system first analyzes and verifies each gated unit based on its registration information to ensure the authenticity and uniqueness of its identity, preventing unauthorized or duplicate device access. Subsequently, according to the pre-designed network plan, the system assigns a unique IP address to each verified gated unit to ensure its independent identity and smooth communication within the network.

[0081] While assigning IP addresses, the system also returns a series of basic parameters based on the type, functional requirements, and system configuration of each access control unit. These basic parameters are essential for the normal operation of the access control unit and the execution of access control tasks, and may include, but are not limited to, access permission settings, communication protocol configuration, alarm thresholds, and time synchronization parameters.

[0082] After receiving the basic parameters, the gate control unit filters and processes the corresponding commands based on the command ID issued by the system. The command ID serves as a unique identifier to distinguish different commands, ensuring that the gate control unit can accurately identify and execute control commands from the system. By parsing the command content, the gate control unit can perform operations such as opening and closing the door, status queries, and permission changes, thereby achieving intelligent and automated access control management.

[0083] Step S4: Retrieve door status information from each of the door control units and synchronize the door status information to the software platform.

[0084] Specifically, to maintain the real-time nature and accuracy of information, the system synchronizes the retrieved door status information to the software platform. As the core management and control center of the access control system, the software platform centrally displays the status information of all door control units, providing managers with an intuitive monitoring interface and real-time data support. Through the software platform, managers can quickly understand the real-time status of each access point, perform remote control and scheduling, and improve the efficiency and security of access control management.

[0085] In addition, this application may also include:

[0086] Heartbeat information is sent to the software platform according to a preset heartbeat cycle.

[0087] Specifically, to ensure the communication connection between the door control unit and the software platform remains active, the system also sends heartbeat messages to the software platform according to a preset heartbeat cycle. A heartbeat message is a simple communication message used to detect whether the connection between the two communicating parties is normal. If the software platform does not receive a heartbeat message from a door control unit within a predetermined time, the system will automatically trigger an exception handling mechanism, which may involve attempting to re-establish the connection, sending a warning notification to administrators, or taking other appropriate emergency measures.

[0088] As can be seen from the above technical solutions, the optical communication access control system, method, device, and readable storage medium provided in this application firstly solves the problem of short data transmission distance and complex wiring between the controller and the access control unit by introducing an optical distribution network as the data transmission medium. Optical communication, with its high bandwidth, long-distance transmission, and low attenuation characteristics, frees access control system data transmission from the physical distance and wiring complexity of traditional wired communication. This design not only simplifies the system's wiring structure and reduces construction difficulty and cost, but also improves the overall performance and reliability of the access control system.

[0089] Secondly, this application enables the controller to flexibly support the number of gating units. Through the data multiplexing function of the optical distribution network, the controller can connect to any number of gating units as needed without changing its hardware or software configuration. This feature not only solves the problem of needing to define multiple controller models due to different numbers of gating units supported, reducing development and maintenance costs, but also enables the system to easily cope with application scenarios of different scales, improving the system's adaptability and scalability.

[0090] Furthermore, thanks to the high-speed transmission capabilities of optical communication and the flexible configuration of the system, this application can also support complex internal linkage logic, such as anti-submarine warfare and interlocking. By precisely controlling the behavior of each gating unit, the service linkage response speed and operational efficiency are improved.

[0091] Figure 5 This is a data interaction diagram based on biological template data for an optical communication access control system disclosed in an embodiment of this application.

[0092] like Figure 5 As shown, in some embodiments of this application, the method may further include:

[0093] The access control unit obtains the biological template assembly data pushed by the access control module, and performs access control permission judgment by comparing the biological templates based on the biological template assembly data. The biological template assembly data is generated by the access control unit through data assembly processing of the biological templates read by the connected reader.

[0094] If the comparison is successful, an opening command is generated and sent to the door control unit.

[0095] Specifically, when the access control unit reads biometric information (such as fingerprints, facial data, etc.) through its connected reader, this raw data undergoes data assembly processing by the access control module to generate biometric template assembly data. This assembled data is then transmitted to the access controller for biometric template comparison. The access controller uses its built-in biometric algorithm to compare the received biometric template assembly data with pre-stored biometric templates of legitimate users in the system. If the comparison is successful, confirming that the person attempting to enter is an authorized user, the access controller immediately generates an opening command and sends this command to the corresponding access control unit via a communication protocol. Upon receiving the opening command, the access control unit executes the corresponding opening operation, allowing the person to pass.

[0096] Furthermore, based on the above, it may also include:

[0097] The system receives the instruction execution result of the gate opening command returned by the gate control unit, and integrates it with the biological template assembly data and the comparison results into a read head result event, which is then sent to the software platform.

[0098] Specifically, to ensure the traceability and security of access control operations, the access controller not only monitors the execution result of the command but also records detailed information about the entire process. After receiving the door opening command execution result from the door control unit, the access controller combines it with the previous biometric template assembly data and comparison results to integrate a complete read head result event. This event contains all the key information of the access control operation, such as user identity, comparison result, and command execution time. Finally, the access controller sends this read head result event to the software platform for administrators to monitor, analyze, and audit, ensuring the secure and efficient operation of the access control system.
