[0033] The present application provides a centralized control device for an access control system, comprising a main control board 10 and a core board 20, wherein the centralized control device is provided with a plurality of first ports 30. The main control board 10 is a key component of the centralized control device, responsible for coordinating and managing the operation of the entire system. It acts as a transit hub for the entire device, enabling data exchange and the transmission of control commands. The main control board 10 is connected between the core board 20 and each first port 30, and is used to configure the first port 30 to be in local area network mode and wide area network mode. The first port 30 here can generally be an RJ45 interface. The main control board 10 itself is connected to both the wide area network and the local area network, but the main control board 10 can control whether the data entering each first port 30 can be routed to the wide area network or can only communicate with devices within the local area network. When the first port 30 is configured in wide area network mode, the data entering the first port 30 can be routed to the wide area network. When the first port 30 is configured in local area network mode, the data entering the first port 30 can only be exchanged within the local area network. In this application, the access control system's primary service, namely access control management, is managed within a local area network (LAN). Other auxiliary services that enrich the access control system's functionality are managed within a wide area network (WAN). Therefore, when the first port 30 is configured in LAN mode, it will be used to connect to access control devices. Since all devices related to access control management services are within the LAN, they can share a single IP address. Data exchange can be achieved using only MAC addresses and the switching function of the main control board 10. Increasing the number of doors does not require additional IP resources, and access control service management is not affected by network quality. Access control devices can be equipped with one or more identity verification modules, such as facial recognition, password entry, fingerprint recognition, palm print recognition, palm vein recognition, and card swiping. When the first port 30 is configured in WAN mode, it can be used to connect to other service devices. Other service devices can be expanded according to the needs of the access control system, such as video surveillance equipment and public broadcasting equipment. The main control board 10 can integrate routing chips, switch chips, and related auxiliary circuits.

[0034] The core board 20 is the central processing unit of the access control system and is responsible for the core business logic processing of the system. It communicates and interacts with each access control device and other business equipment through the main control board 10. Specifically, the core board 20 communicates with the access control device through the main control board 10 using the local area network, and the core board 20 communicates with other business equipment through the main control board 10 using the wide area network. The core board 20 stores the relevant code and required data for the access control business processing flow, as well as the relevant code and required data for other business processing flows. When the main control board 10 transfers data to the core board 20, the core board 20 can determine whether the data packet belongs to the access control business or other business based on the identifier on the data packet, so that the appropriate process can be called to start business processing.

[0035] The centralized control device of the access control system provided in the present application is composed of a main control board 10 and a core board 20, and is provided with a plurality of first ports 30. The main control board 10 serves as a transit hub for the entire device, connecting the core board 20 and each first port 30. It can configure the first port 30 to be in LAN mode or WAN mode. When the first port 30 is configured to be in LAN mode, it is used to connect access control devices. All these devices are within the same LAN and can share an IP address, thereby saving IP resources and not being affected by network quality. When the first port 30 is configured to be in WAN mode, it is used to connect other business equipment and can be expanded as needed. The core board 20 is the central processing unit of the access control system. It communicates with the access control equipment via the LAN through the main control board 10, and communicates with other business equipment via the WAN. It manages access control management services and other services through the LAN and WAN respectively. Access control devices distributed across the country can be centrally controlled by a centralized control device, making maintenance more convenient. In addition, the access control management of this solution is not affected by network interference, and limited IP resources can also manage a large number of doors, making the access control system highly reliable, scalable, and easy to manage.

[0036] In one embodiment, the first port 30 is a POE power port. POE (Power over Ethernet) is a technology that transmits data and power to terminal devices via standard Ethernet cables. The main control board 10 integrates a POE switch chip, which provides data transmission and power supply functions for the connected first port 30. POE technology utilizes the four unused wire pairs (non-data pairs) of the Ethernet cable to power devices. After detecting whether the connected device is a POE device and negotiating power, the POE power supply device (the main control board 10 in this example) loads DC power onto the Ethernet cable to power the remote POE terminal device (such as an access control device). This allows data transmission and power supply to be achieved over the same cable, eliminating the need for separate wiring. This effectively simplifies the wiring of the controller body and reduces project site issues such as wiring errors, installation costs, and labor maintenance costs. Furthermore, since power is concentrated at one end of the main control board 10, system security and manageability are improved. Furthermore, the entire centralized control device can be rack-mounted, with multiple first ports 30 neatly arranged on the main housing of the centralized control device.

[0037] In one embodiment, the main control board 10 is further configured to, upon receiving data transmitted from the first port 30 in the LAN mode, set a first identifier for the data and forward it to the core board 20 via the LAN. The main control board 10 is further configured to, upon receiving data transmitted from the first port 30 in the WAN mode, set a second identifier for the data and forward it to the core board 20 via the WAN.

[0038] It can be understood that the main control board 10 needs to classify the data transmitted from the first port 30 according to the configuration of each first port 30, so as to facilitate their transmission through the isolated local area network link and wide area network link. For example, two logical processing units can be configured in the main control board 10. The first logical processing unit and the second logical processing unit can both receive data transmitted from the first port 30, and both maintain a port configuration table to determine which mode each first port 30 is in. The first logical processing unit is used to mark the data transmitted from the first port 30 in the local area network mode with a first identifier. The second logical processing unit is used to mark the data transmitted from the first port 30 in the wide area network mode with a second identifier.

[0039] Specifically, VLAN technology can be used to divide the first ports 30 in the two modes, assigning them different VLAN identifiers. Each VLAN identifier has an independent relay link on the switch chip. This allows the switch chip to select the corresponding relay link based on the first and second identifiers during processing. Specifically, the switch chip can forward data with the first identifier to the core board 20 via a relay link connected only to the local area network. It can also forward data with the second identifier to the core board 20 via a relay link connected to the wide area network.

[0040] When the core board 20 receives a data packet, it will determine which service processing logic to start to process the data carried in the data packet based on the identifier on the data packet. Specifically, if the data packet carries a first identifier, the access control service processing logic will be used to process the data with the first identifier. If the data packet carries a second identifier, other service processing logic will be used to process the data with the second identifier.

[0041] In one embodiment, the core board 20 selects the access control business processing logic to process the data with the first identifier, which may include: the core board 20 is used to extract identity authentication information from the data with the first identifier, compare and verify it with the pre-stored authorization identity information, and obtain verification feedback based on the verification result. It can be understood that when the core board 20 receives a data packet with the first identifier, it will identify that the data packet belongs to the access control business and call the access control business processing logic for processing. Specifically, the core board 20 first extracts identity authentication information from the data packet, such as card swiping information, biometric information, etc. Then, the core board 20 compares and verifies the extracted identity authentication information with pre-stored authorization identity information, such as access control card number, biometric template, etc. Through comparison and verification, the core board 20 can obtain the verification result and determine whether the access control can be passed.

[0042] In addition, the core board 20 also needs to transmit the verification feedback back to the corresponding first port 30. The received data packet has MAC address information about the first port 30, but the core board 20 needs to retransmit it back using the local area network. Two virtual network cards can be set in the core board 20, the first virtual network card corresponds to the local area network transmission, and the second virtual network card corresponds to the wide area network transmission. When the first virtual network card packs the verification feedback, it will mark it with the first identifier. Then the data will only be transmitted from the relay link corresponding to the first identifier to the main control board 10, that is, through the local area network to the main control board 10. After the main control board 10 receives the verification feedback, it unpacks it to obtain the MAC address information of the target first port 30, so as to continue to use the local area network to feed back the verification feedback information to the target first port 30 to control the access control device connected by the target first port 30 to be unlocked or remain locked. When the core board 20 needs to send information to the first port 30, it will use the first virtual network card and the address information of the target first port 30 to encapsulate the data packet, so as to control the access control device connected to the first port 30.

[0043] In one embodiment, the centralized control device is provided with at least one second port 40 for connecting the server side. Unlike the first port 30, the second port 40 is a permanent wide area network mode, which is used to connect the server side. Therefore, the core board 20 and the server side will communicate through the main control board 10 using the wide area network. The server side here can be an access control management server, which centrally stores and manages related data of the access control system, such as personnel information, access control policy, access control record, authorized identity information, etc. It can also be a remote monitoring server connected to video monitoring equipment, alarm host, etc., to realize remote video monitoring and alarm monitoring of the scene. It can also be a cloud service platform that can provide remote access control, data management, system maintenance, etc. Cloud services realize unified centralized management and control of multiple systems and cross-regional. The second port 40 can generally be an RJ45 interface.

[0044] In one embodiment, the main control board 10 is also used to set a second identifier for the data transmitted from the second port 40 when receiving the data, and forward it to the core board 20 through the wide area network. Specifically, the data transmitted from the second port 40 will only be received by the second logical processing unit of the main control board 10, which will mark it with the second identifier, so as to transmit the data transmitted from the second port 40 to the core board 20 using the relay link corresponding to the second identifier. The main control board 10 can use VLAN isolation and routing forwarding technology to forward the data packet marked with the second identifier to the second virtual network card of the core board 20 through the wide area network VLAN. This method ensures the logical isolation of server side business data and access control local business data, and avoids mutual interference.

[0045] In one embodiment, the data transmitted from the second port 40 includes authorization identity information. The core board 20 is also used to save the authorization identity information locally. The authorization identity information in the core board 20 comes from the server side, so other business processes include saving the authorization identity information transmitted from the server side locally. Specifically, the server side packages the authorization identity information according to the protocol used in the wide area network through the second port 40 and sends it to the main control board 10. The second logic processing unit in the main control board 10 marks the data packet with a second identifier. The main control board 10 can then transmit the data packet to the core board 20 using the relay link corresponding to the second identifier. After identifying the second identifier, the core board 20 selects the relevant code of other business processing processes. Then, the relevant instructions and authorization identity information are extracted from the data packet, and the authorization identity information is stored locally under the instruction of the instruction.

[0046] In one embodiment, the data transmitted from the second port 40 includes a remote unlock request. The core board 20 is further configured to generate an unlock instruction based on the remote unlock request, set a first identifier for the unlock instruction, and forward the unlock instruction to the main control board 10. Based on the first identifier, the main control board 10 selects the local area network to feed the unlock instruction back to the corresponding first port 30 to control the unlocking of the access control device.

[0047] It can be understood that the server side is configured with a corresponding web side or applet side, and the authorized user can send an unlock instruction to the server side through the web side or applet side. The server side generates a remote unlock request and packages it according to the protocol used in the wide area network, and then sends it to the main control board 10 through the second port 40. The second logic processing unit in the main control board 10 marks the data packet with a second identifier. The main control board 10 can then transmit the data packet to the core board 20 using the relay link corresponding to the second identifier. After identifying the second identifier, the core board 20 selects the relevant code of other business processing procedures. The remote unlock request is then extracted from the data packet, which includes the local area network communication address of the first port 30 connected to the access control device to be unlocked. The core board 20 generates an unlock instruction based on this, and uses the first virtual network card to set a first identifier for the unlock instruction, and after packaging it according to the protocol used in the local area network, it is transmitted to the main control board 10 using the relay link corresponding to the first identifier. The main control board 10 transmits the LAN communication address in the unlock instruction to the corresponding first port 30 via the relay link corresponding to the first identifier, so as to open the access control device connected to the first port 30 .

[0048] In addition, the access control device will transmit the door switch status, reader connection status, power supply status, etc. to the core board 20 through the main control board 10 and the local area network. Other business devices will transmit the network status, power supply status, etc. to the core board 20 through the main control board 10 and the wide area network. The main control board 10 will also transmit the status of each chip integrated into it to the core board 20 through the local area network. The core board 20 will then transmit this status information to the server side through the main control board 10 and the wide area network, allowing users to directly query the status of the entire system through the web side or the applet side. In addition, users can directly upgrade the firmware, restore factory settings, restart, etc. of the core board 20 and the control board through the web side or the applet side. The data interaction process is similar to sending a remote unlock request.

[0049] In one embodiment, the core board 20 is further configured to generate a verification record based on the verification result of the comparison between the identity authentication information and the authorized identity information, set a second identifier for the verification record, and send the verification record via the wide area network to the main control board 10. The main control board 10 is further configured to send the verification record with the second identifier to the server via the wide area network.

[0050] It is understandable that the server side needs to collect the usage records of each access control device for the convenience of management. Therefore, when the core board 20 executes an access control business management process, it is necessary to send the records to the server side. Therefore, after obtaining a verification result, the core board 20 will generate a verification record based on the current time, the number of the corresponding access control device and other information. The second virtual network card is then used to set the second identifier and the IP address of the server side for the verification record, and after packaging it according to the protocol used in the wide area network, it is transmitted to the main control board 10 using the relay link corresponding to the second identifier. The main control board 10 transmits the verification record to the corresponding second port 40 using the relay link corresponding to the second identifier based on the second identifier and the IP address therein, so as to transmit the verification record back to the server side.

[0051] In one embodiment, the centralized controller may further include a third interface connected to the core board 20. The third interface is configured to connect to a fire alarm system. The fire alarm system transmits a fire alarm signal to the core board 20 via the third interface. The core board 20 transmits the fire alarm signal via the main control board 10 and the local area network, broadcasting an unlock command to the first port 30 of all LAN-connected devices, thereby controlling the unlocking of all access control devices.

[0052] It can be understood that access control can also be linked with fire safety. When a fire is detected, the fire alarm system generates a fire alarm signal and sends it directly to the core board 20 through the third port. The core board 20 generates an unlock instruction in response to the fire alarm signal, and uses the first virtual network card to set a first identifier for the unlock instruction. After packaging it according to the protocol used by the local area network, it is transmitted to the main control board 10 using the relay link corresponding to the first identifier, and the main control board 10 is instructed to broadcast the data packet to the first port 30 of all local area network modes. The main control board 10 uses the relay link corresponding to the first identifier to transmit it to the first port 30 of all local area network modes according to the instructions to open all access control devices and facilitate escape.

[0053] In one embodiment, the centralized control device also includes a Wi-Fi module, with the main control board 10 connected to the Wi-Fi module. A Wi-Fi module is a wireless communication module that integrates a Wi-Fi radio transceiver and antenna, enabling wireless connections with other Wi-Fi devices and data transmission. To achieve this, the Wi-Fi operating mode must be configured as "access point mode." The SSID (wireless network name) for the hotspot is set, an appropriate security authentication mode (such as WPA2-PSK) is selected, and a password is set. An IP address segment is allocated for Wi-Fi client connections, and a DHCP server is enabled to automatically assign IP addresses to connected Wi-Fi clients. By adding a Wi-Fi module and providing hotspot functionality, the centralized control device for the access control system not only supports traditional wired LAN and WAN access, but also adds flexible wireless access capabilities. Data exchanged between devices connected via the Wi-Fi hotspot and the main control board 10 is also processed by the second logic processing unit. This uses a relay link corresponding to the WAN mode, allowing mobile devices to directly connect to the WAN via Wi-Fi and access websites, applets, and other platforms to manage and control the access control system. This provides wireless access capabilities, enabling flexible and convenient system deployment and maintenance. No on-site wiring is required, saving network cabling costs and engineering effort. Local configuration and remote access can be completed on a mobile phone in one stop, enhancing the user experience.
