[0051] Please see Figure 1 , Figure 1 This is a schematic diagram illustrating a method for demonstrating a digital twin model of an airport network provided by the present invention, as shown below. Figure 1 As shown, the method includes:

[0052] S11. Obtain basic equipment information and management information of each network device in the airport network.

[0053] In this embodiment, general-purpose network management tools or custom scripts can be used to extract configuration information from various devices in the airport network. These devices include, but are not limited to, critical network devices such as routers, switches, and firewalls. These tools or custom scripts can establish connections with the devices via protocols such as SNMP, SSH, and Telnet, and obtain key data such as device type, model, port configuration, IP address, and routing information. The extracted information needs to be based on the configuration templates of different manufacturers to complete the data extraction.

[0054] In this embodiment, the basic device information includes: physical attribute information and configuration attribute information of the network device. Specifically, the physical attribute information includes: device type, model, number of ports, etc., and the configuration attribute information includes: device IP address, routing table, access control list, etc.

[0055] In this embodiment, the management information includes: the device's code, the airport, terminal, and activation time. This management information can be collected by the machine equipment through monitoring or by staff actively entering it into the data entry device. It can also be obtained through multiple collaborative methods, forming a supervision between different methods to ensure the accuracy of the relevant management attributes.

[0056] Specifically, management information is generated based on the device management information and line management information entered in each network device. Device management information includes: network device code, airport, terminal, activation time, device type, device brand, device model, device ownership, device name, management IP, and purpose. Line management information includes: network line code, primary / backup type, line type, line operator, departing line bandwidth, leased line number, fault reporting telephone number, shared terminal, associated local airport device port, and associated uplink device port.

[0057] S12. Generate an equipment information profile based on basic equipment information and management information.

[0058] In this embodiment, based on graph theory and network modeling techniques, real network devices, connection relationships, and configuration information are mapped to a virtual digital space. The organic combination of this information meets the essential needs of civil aviation airport network operation and maintenance, enabling it not only to reflect the static structure of the network but also to show the network management context. This allows users to see the device information profiles corresponding to each network device at a glance, facilitating subsequent management and maintenance.

[0059] Specifically, based on the physical attribute information, connection relationship information, and configuration attribute information of each network device, each network device is mapped to a virtual digital space; management information is supplemented in each network device mapped in the virtual digital space to generate a device information profile.

[0060] S13. Based on the device connection relationships of network devices, associate the information profiles of each device to generate a digital twin model of the airport network.

[0061] In this embodiment, connection relationships are generated between various device information profiles in the digital space based on the connection relationships of network devices, thus constructing a digital twin model of the entire airport network. The connection relationships between network devices include wired and wireless connections. In this scheme, the connection relationships between network devices can be constructed using network layer routing table information to build the forwarding relationships of devices. Since the forwarding rules of network devices depend on multiple routing protocols, in addition to the static network protocols configured by the network administrator, dynamic routing protocols such as RIP (Routing Information Protocol), OSPF (Open Shortest Path First), and BGP (Border Gateway Protocol) are also used to complete the construction of the routing table. Network devices rely on this information to calculate the path to the destination address.

[0062] In this embodiment, the communication path selection information in the routing table is used as the device connection relationship. The next address of the target network segment or IP address is associated with the digital profile of all airport node network devices to obtain the communication forwarding topology relationship model between devices. This communication forwarding topology relationship model is used as the device connection relationship of the network devices.

[0063] Specifically, the next address of the target network segment and / or IP address is determined by using the communication path selection information in the routing table; the routing path between the target network segment and / or IP address and the device corresponding to the next address is used as the device connection relationship.

[0064] S14. Based on the digital twin model, a multi-layered network view is generated and displayed according to the airport node topology relationship, the airport node local network topology relationship, and network device information.

[0065] In this embodiment, based on the completed digital twin model, the digital twin model is divided into a multi-layered network view according to the airport node topology relationship, the airport node local network topology relationship, and network device information, so that users can intuitively view the status of devices in different layers of the airport network.

[0066] In this embodiment, the network view in this solution is the airport network at different levels. These views abstract and describe the network at different levels according to the networking characteristics of civil aviation airport networks, so that operation and maintenance personnel can quickly understand the overall architecture and key information of the network.

[0067] In this embodiment, considering the star topology of my country's civil aviation airport network, we divide the digital twin display into three layers. The first layer displays the national airport node and line topology in map form; the second layer displays the local network and line topology of each airport node; and the third layer displays detailed information about the digital profiles of the equipment. This module intuitively displays the connection relationships between nodes within the airport and detailed information about key equipment. Through this view, operations and maintenance personnel can intuitively understand the overall layout and key nodes of the airport network.

[0068] Specifically, in this solution, when the network view is displayed, it first shows the first layer, which displays the national airport nodes and the line topology between each airport node. By clicking on each airport node in the first layer network view, you can enter the second layer network view of the corresponding airport node. The second layer network view displays the network devices in that airport node and the line topology between the network devices. By clicking on each network device in the second layer network view, you can enter the third layer network view of the corresponding network device, which displays the information profile of that network device.

[0069] In this embodiment, by acquiring the basic and management information of each network device in the airport network and generating a device information profile for each network device, and combining the device connection relationships of the network devices, a digital twin model of the airport network is constructed. Based on the digital twin model, multi-level network views at different levels are generated to better display the information in the digital twin model. This not only improves the efficiency and accuracy of network management, but also provides maintenance personnel with a powerful and convenient network monitoring and management platform, providing strong technical support for the safe and efficient operation of civil aviation airports.

[0070] like Figure 2 As shown, Figure 1 This invention provides a flowchart illustrating a method for constructing a multi-layered network view. Specifically, step S14, constructing a multi-layered network view, includes the following steps:

[0071] S21. Generate a multi-level network view.

[0072] In this embodiment, according to the scheme in the above embodiments, a three-layer network view is generated, and the information displayed in the digital twin model is layered at different levels, so that operation and maintenance personnel can quickly understand the overall architecture and key information of the network at different levels.

[0073] S22. Based on the digital twin model, render and generate the location of each airport node on the map and the route topology of each airport node in the first layer of the network view.

[0074] S23. Based on the digital twin model, render and generate the line topology of each network device in each airport node in the second layer of the network view.

[0075] S24. Based on the digital twin model, render and generate device information profiles for each network device in the third layer of the network view.

[0076] In this embodiment, based on the information in the digital twin model, the network view is abstracted and described at different levels. These views conform to the networking characteristics of civil aviation airport networks, and when operation and maintenance personnel view the network views at different levels, they can clearly see the relevant information.

[0077] like Figure 3 As shown, in this embodiment, step S23 renders and generates the line topology of each network device in each airport node in the second layer of the network view, including the following steps:

[0078] S31. Based on the connection relationship of network devices in the digital twin model, determine the uplink data center line and uplink data center device of the airport node, and render and generate the interconnection area between the airport node and the uplink data center in the second layer of the network view; the interconnection area between the airport node and the uplink data center includes: uplink data center device, network device connected to the uplink data center device, and connection line between the uplink data center device and the network device.

[0079] In this embodiment, for the local network and line topology of the second-layer airport node, in order to dynamically construct the airport topology information through digital twin model information, the topology is divided into three regions: "Airport node connecting to data center region", "Airport node connecting to airport local network interconnection region", and "Downstream airport interconnection region". "Airport node connecting to data center region" is the interconnection region between the airport node and the upstream data center in this scheme. "Airport node connecting to airport local network interconnection region" is the interconnection region of network devices in the airport node in this scheme. "Downstream airport interconnection region" is the downstream airport interconnection region in this scheme.

[0080] In this embodiment, for the airport node connecting to the data center area, the "Purpose" attribute in the digital twin model is displayed as "Uplink Device and Uplink & Connect to Airport Device," and the uplink data center lines and uplink data center devices are associated based on the network device connection relationships. The uplink data center devices are placed within the data center area, and device icons and lines are drawn according to the "Device Type" attribute in the digital twin model. All devices are connected to the airport node network backbone via lines; devices with the "Purpose" attribute of "Uplink & Connect to the Airport" require additional lines to connect to the airport equipment connection backbone.

[0081] S32. Based on the connection relationship of network devices in the digital twin model, render and generate the network device interconnection area in the airport node in the second layer of the network view. The network device interconnection area in the airport node includes: the network devices in the airport node and the connection lines between the network devices.

[0082] In this embodiment, for the airport node connecting to the airport's local network interconnection area, the "Purpose" attribute in the digital twin model is displayed as "Interconnection switches and airport connection equipment", and the equipment icon and lines are drawn according to the "Equipment Type" attribute.

[0083] S33. Based on the connection relationship of network devices in the digital twin model, determine the downstream airport nodes of the airport nodes, and render and generate the downstream airport interconnection area in the second layer of the network view; the downstream airport interconnection area includes: the downstream airport nodes, the network devices connected to the downstream airport nodes, and the connection lines between the downstream airport nodes and the network devices.

[0084] In this embodiment, for the downstream airport interconnection area, the "Purpose" attribute in the digital twin model is displayed as "Downstream Small Departure Equipment," and the downstream lines (information and quantity) and downstream node names are associated based on the network device connection relationships. Each downstream node is represented by this node name and has the function of drilling down into the downstream node topology. Device icons and lines are drawn according to the "Device Type" attribute. The display of drilling down into the downstream node topology conforms to the local network and line topology rules of the second-layer airport node.

[0085] In this embodiment, in addition to the aforementioned areas, the implementation plan also includes auxiliary views such as a network leased line view and an alarm information view. The network leased line view displays the connection status and bandwidth utilization of each leased line within the airport; the alarm information view displays alarm information in the network in real time. Overlaying this information in a hierarchical view provides maintenance personnel with an intuitive means of monitoring and management.

[0086] See Figure 4 , Figure 4 This is a schematic diagram illustrating a method for demonstrating a digital twin model of an airport network provided by the present invention, as shown below. Figure 4 As shown, with Figure 1 Compared to the illustrated embodiment, the method further includes:

[0087] S41. Periodically poll the basic and management information of each network device.

[0088] S42. When basic information or management information changes, the digital twin model is updated using the changed basic information and management information.

[0089] In this embodiment, to ensure that the digital twin model remains synchronized with the real civil aviation airport network, a real-time update and maintenance mechanism is established to guarantee the accuracy and timeliness of the digital twin model. This mechanism maintains the digital twin model through an update and maintenance module. This mechanism obtains the latest network configuration information and status data in real time by periodically scanning network devices and monitoring network events. Once new configuration information or changes in network status are detected, the digital twin model is immediately updated. In this way, the digital twin model can always maintain its accuracy and timeliness, providing maintenance personnel with the latest and most reliable network status information.
