At the same time, the key nodes of optical fiber connection are accurately identified, such as the connection relationship between optical fiber ports of ODF racks, junction boxes, distribution frames and other equipment. In addition, considering the importance of safe operation, the model must also accurately incorporate the grounding system design of the smart substation, including details such as the location and connection method of the grounding grid, grounding lead, and grounding device.

The intelligent assistance system can capture and analyze the current status and structural characteristics of the fiber optic network in real time, and generate accurate operation instructions and prompt information based on preset rules and algorithm logic. For example, in the 3D view, the system can dynamically mark the best fiber optic wiring path, and guide the staff to perform the correct operation through highlighting or arrow pointing, which significantly reduces the possibility of getting lost in the huge and complex network environment. According to the operation and design specifications, the fiber optic wiring operations being performed by the staff are verified in real time, and when potential errors or deviations from the specifications are found, warnings and intelligent correction suggestions are immediately issued to ensure that each step of the operation can accurately meet the standard requirements. This instant feedback mechanism greatly improves the execution speed and accuracy of fiber optic wiring tasks, and also reduces the risk of failures that may be caused by human factors.

This database contains the basic attributes of each node, such as device type, model, installation location, etc., and also includes detailed information coding of the connections between nodes. By simply scanning or entering the core number, the corresponding optical fiber can be immediately found in the database, thereby constructing a complete, dynamically updated optical fiber link logical structure map.

[0024] The above-mentioned method for 3D visualization of optical fiber links in smart substations based on twin technology is characterized in that: in the intelligent identification and early warning steps, the system can display and identify changes in the state of logical links in real time. When abnormal changes that may affect the normal operation of the link are detected, an early warning notification is immediately triggered. During operations such as optical fiber plugging or docking, the operational risks are evaluated in advance and preventive warnings are given to prevent accidental link breaks or logical errors. When an electrical fault causes an alarm, the system can quickly identify the optical fiber logical link where the electrical fault is located, accurately locate the specific location of the fault, shorten the troubleshooting time, and improve the efficiency of emergency repairs. Combined with historical data and machine learning algorithms, potential faults can be predicted and analyzed to improve the stability and reliability of optical fiber links.

[0025] In the step of constructing the 3D visualization model of the optical fiber path of this application, GIS and BIM technologies are combined to create a 3D digital model copy of the optical fiber network inside the smart substation. The model not only displays the optical fiber path in three dimensions, but also supports interactive operations, quickly retrieves and locates the optical fiber core through automatic recognition technology, and dynamically tracks and displays it, providing intuitive guidance for staff. Deeply integrate geographic information system (GIS) and building information model (BIM) technology, use GIS technology to accurately store and manage the spatial geographic information of the optical fiber network, and accurately reproduce the optical fiber path in three-dimensional space through the geographic coordinate system. At the same time, BIM technology will be used to describe the construction details and attribute information of the optical fiber network in detail, including the components of the network, the core structure, and the logical connection between the equipment. Based on GIS and BIM technology, a three-dimensional digital model copy that is highly consistent with the actual optical fiber network is constructed. The model will accurately reflect the distribution area, direction path, and spatial relationship of the optical fiber with other power facilities, providing managers with an intuitive three-dimensional perspective.

The system simplifies the understanding of complex fiber optic networks with three-dimensional views, and integrates intelligent prompts and verification functions to provide real-time operation guidance. During the alignment process, the system automatically detects potential errors and provides correction suggestions, predicts fault points, and ensures the accuracy of alignment work and the reliability of the communication network.

[0027] In the steps of constructing the optical fiber logic link intelligent identification and early warning system of the present application, an intelligent system is constructed to monitor the status of the optical fiber logic link and perform fault diagnosis. The system will establish the optical fiber logic link in segments according to the logic of the optical fiber link, and provide early warnings during operations such as optical fiber plugging or docking. When an electrical fault occurs, the system can indicate the optical fiber communication logic link where the fault is located.

[0028] This application mainly solves the following key problems in power infrastructure: (1) Difficulties in fiber optic path management: Traditional fiber optic path management often relies on manual recording and inspection, which is inefficient and prone to errors. Through digital twin technology, 3D visualization of fiber optic paths is achieved, making complex fiber optic layouts clearly visible, solving the problem that fiber optic paths are difficult to intuitively present and manage. (2) Reliability of fiber optic communication: Fiber optic communication is a key link in power infrastructure. Traditional manual wiring methods are prone to errors and inefficient. Failures in fiber optic core wiring may cause serious communication interruptions. 3D visualization technology provides intuitive and accurate operation guidance for operation and maintenance personnel, greatly reducing failures caused by improper manual operation. (3) Delayed fiber optic fault location and diagnosis: Fiber optic fault troubleshooting usually requires a lot of time to detect section by section, and the response speed to sudden faults is slow. Through fiber automatic identification technology and real-time monitoring and early warning functions, rapid positioning of fiber optic cores and early detection of faults can be achieved, significantly shortening the troubleshooting time.
