Description

Methods, systems, equipment, and media for visualizing nuclear power plant cable paths Technical Field

[0001] This invention relates to the field of three-dimensional visualization technology, and in particular to a method, system, device and medium for generating visualizations of nuclear power plant cable paths. Background Technology

[0002] With the rapid development of digital information technology and 3D visualization technology, digital design and 3D display methods have been gradually applied to the design, construction, and operation and maintenance of nuclear power plants. Based on the 3D layout design model of the Plant Design Management System (PDMS) formed during the construction phase of nuclear power plants, engineers can combine lightweight modeling and 3D digitization technology to build a visualized and intelligent nuclear power plant platform. This enables 3D display and online monitoring of the plant structure, equipment layout, and operating status, providing a foundation for panoramic digital management of nuclear power plants.

[0003] However, in actual cable engineering design, the problems of a huge number of cables and scattered and complex data still exist. For example, a nuclear power plant has approximately 9,000 electrical unit cables and approximately 22,000 instrumentation and control unit cables, totaling more than 30,000 cables. Each cable contains about 20 key data items for termination and route design. Although 3D digital technology has been applied to overall plant modeling, cable tray and cable laying design still mainly rely on the traditional list management mode. This makes it difficult to intuitively associate cable information in the 3D model, and the maintenance, use, and sharing of cable data are inefficient, failing to meet the current needs of nuclear power plants for digital, visual, and efficient management of cable data. Therefore, there is a need to provide a method, system, equipment, and medium for visually generating cable routes in nuclear power plants. Summary of the Invention

[0004] This invention provides a method, system, device, and medium for visually generating cable paths in nuclear power plants, in order to improve the technical problem that existing nuclear power plant cable data is difficult to automatically associate with three-dimensional models and visualize, resulting in low efficiency in cable path verification.

[0009] In one embodiment of the present invention, after all nodes have been processed, the method further includes: for each node that does not have a spatial attribute, performing the following interpolation processing as the current node: interpolating the global spatial coordinates of each node adjacent to the current node to generate the global spatial coordinates of the node; generating the direction vector of the current node based on the direction vectors of each node adjacent to the current node, and using the generated global spatial coordinates and direction vector as the spatial attributes of the current node.

[0010] In one embodiment of the present invention, the node spatial information includes the global spatial coordinates, direction vectors, and component identifiers of the nodes in a preset three-dimensional model.

[0011] In one embodiment of the present invention, the smoothing process is B-spline smoothing.

[0012] In one embodiment of the present invention, the cable data includes multiple cable sub-data, each cable sub-data corresponding to the laying status of a cable.

[0014] In one embodiment of the present invention, when the display strategy is system-wide display, the step of generating a visual display result of the cable path corresponding to the display strategy based on the cable path spatial information of the target cable includes: for each target cable corresponding to the system: generating a three-dimensional geometric model corresponding to the target cable based on the cable path spatial information of the target cable; loading the corresponding cable tray model and equipment model from a preset three-dimensional spatial model library based on the node names of each node in the cable path spatial information of the target cable; combining and rendering the three-dimensional geometric model of each target cable with the corresponding cable tray model and equipment model, and displaying different target cables in different colors to generate a visual display result of the cable path under the system scope.

[0015] In one embodiment of the present invention, when the display strategy is to display the factory area, the step of generating a visualization display result of the cable path corresponding to the display strategy based on the cable path spatial information of the target cable includes: for each target cable corresponding to the factory: generating a three-dimensional geometric model corresponding to the target cable based on the cable path spatial information of the target cable; loading the corresponding cable tray model and equipment model from a preset three-dimensional spatial model library based on the node names of each node in the cable path spatial information of the target cable; loading the three-dimensional factory background model corresponding to the factory from the background model library based on the factory's identifier; and globally combining and rendering the three-dimensional geometric model of each target cable with the corresponding cable tray model, equipment model, and three-dimensional factory background model to generate a visualization display result of the cable path within the factory area.

[0016] In one embodiment of the present invention, after generating the visualization result of the cable path within the factory area, the method further includes: responding to the visible area of ​​the current camera, dynamically loading a three-dimensional factory background sub-model corresponding to the current visible area from the three-dimensional factory background model.

[0020] The beneficial effects of this invention are as follows: This invention proposes a method, system, device, and medium for visually generating cable paths in nuclear power plants. By acquiring cable data characterizing the cable laying situation and parsing the path information, the original path description is decomposed into multiple nodes arranged according to the actual laying sequence. For each node, its spatial position and orientation attributes in a three-dimensional scene are extracted to construct node spatial information. Based on the arrangement order of the nodes, the spatial information of each node is sequentially arranged to generate the cable path spatial information. Visualizing this spatial information generates a three-dimensional display of the cable, making the cable laying structure readily apparent. This invention not only improves the efficiency and accuracy of cable path parsing but also enables the cable laying situation to be presented intuitively in a visual manner, significantly improving the visualization capabilities and digital management level of nuclear power plant cable design, verification, and operation and maintenance.

[0027] The inventors discovered that the traditional list-based management method is still widely used in the design of cable trays and cable laying in nuclear power plants. Cable data for different systems is maintained separately by each discipline, resulting in inconsistent list formats, numerous interfaces, and scattered data sources. This necessitates manual collation and comparison of cable information provided by each discipline during cable tray laying design or cross-disciplinary data aggregation, which is both labor-intensive and inefficient. Due to the lack of digital and visualization support, designers cannot visually view the actual cable laying path within the plant area. Information such as whether the cable's starting and ending points have been modeled and whether its position in 3D space is accurate can only be manually checked point by point in the PDMS, a tedious and error-prone process. Furthermore, cable termination information is frequently updated due to changes in upstream process loads and distributed control systems (DCS). Under the list-based model, the maintenance, sharing, and reuse capabilities of cable data are weak, making it difficult to guarantee data integrity, accuracy, and consistency. Therefore, a large amount of manpower is often required for repeated verification, severely impacting the overall project schedule. Therefore, there is an urgent need for a digital, structured, and visualized cable data management and 3D display technology to improve the efficiency and accuracy of data utilization during the cable design and operation and maintenance phases.

[0028] This invention provides a method for visually generating cable routes in nuclear power plants, enabling the digitization, structuring, and 3D processing of cable routes within the complex cable laying environment of nuclear power plants. By automatically parsing cable inventory data, generating 3D spatial coordinate information corresponding to route nodes and establishing batch automatic associations with 3D entity models, this not only significantly reduces the error rate of manual verification but also achieves rapid generation and visualization of 3D cable route models. This invention can intuitively present the cable laying direction, starting and ending equipment, and 3D model information of the cable trays along the route, enabling maintenance personnel to carry out maintenance work more efficiently and providing designers with a convenient means to verify the integrity and location accuracy of the model. Furthermore, this invention achieves structured management of cable data through the digital storage and visualization of cable termination data, improving the accuracy, completeness, and usability of cable inventory data. Relying on the PDMS 3D design model, this invention can realize the batch generation and display of multi-dimensional, multi-cable 3D routes, significantly improving the efficiency and visualization level of cable management, and constructing a more convenient, intuitive, and intelligent 3D visualization application system for nuclear power plant cables.

[0029] As shown in Figure 1, the visualization generation method for nuclear power plant cable paths includes the following steps: S100, obtaining cable data to characterize the cable laying situation.

[0030] Structured cable data is acquired, including sequentially recorded cable codes, starting and ending equipment codes, and path information representing the actual cable route. The cable code serves as a unique identifier for the cable and can be used to retrieve associated 3D model information from a 3D design component library. This establishes a traceable link between cable data and 3D model objects, providing a data foundation for subsequent 3D spatial positioning and visualization. It can be understood that cable data can correspond to a single cable or a set of cable sub-data. When cable data corresponds to multiple cables, the subsequent cable path visualization generation process can be performed separately for each cable sub-data in the cable set.

[0031] S200. The path information of the cable data is parsed and processed to obtain multiple nodes arranged in the path order; the path information is used to describe the cable path.

[0032] Since path information often includes cable tray names, connector numbers, equipment port identifiers, etc., and follows the actual route of the cable within the factory, path information can be segmented and decomposed based on path parsing rules. This allows for the identification of various nodes, such as equipment nodes, cable tray nodes, and connector nodes, according to their positional order within the path information. Each node corresponds to an actual physical structure of the cable within the factory (such as an equipment port or cable tray segment). Through this parsing process, path descriptions, originally expressed as strings and difficult to use directly for spatial calculations, can be transformed into a sequentially arranged, structured sequence of nodes, facilitating subsequent path visualization generation.

[0033] In an optional embodiment of the present invention, step S200 includes the following process: based on a preset path parsing rule, the path information is segmented to obtain candidate strings for multiple nodes; node type identification is performed on each candidate string to obtain the node type corresponding to each candidate string.

[0034] Since path information includes a structured string sequence consisting of cable tray section names, equipment port labels, and connector changes recorded according to the cable laying sequence, a complete path can be decomposed into multiple candidate strings based on preset delimiters, naming conventions, or path hierarchy rules. Each candidate string corresponds to a node position of the cable in the actual spatial path. This segmentation method breaks down the originally continuous path information into several independent candidate nodes. After obtaining the candidate strings, for each candidate string, based on its corresponding naming convention, field structure, or positional relationship within the path, it is determined whether the candidate string belongs to a device node, cable tray node, connector node, or other node type. For example, if the candidate string begins with a preset device code, it is treated as a device node; if the candidate string carries a preset cable tray prefix, it is treated as a cable tray node.

[0035] S300. Extract the node spatial information corresponding to each node; where the node spatial information is used to characterize the spatial position and pose attributes of the corresponding node in the three-dimensional scene.

[0036] After identifying the type of each node in the cable path, the corresponding 3D component can be retrieved from the PDMS's pre-set 3D design component library based on the node's identifier, and node spatial information for each node can be generated accordingly. The node spatial information characterizes the spatial attributes of the node in the 3D factory scene. It is a set of spatial parameters for the node in the 3D environment, including the node's spatial position and orientation attributes in the global coordinate system. Spatial position describes the node's global spatial coordinates in the overall 3D factory coordinate system, which may include the component center point coordinates, port geometric center coordinates, or component positioning point coordinates. Orientation attributes describe the node's orientation in the 3D scene and the component identifier of the corresponding 3D component, which may include the orientation vector and component identifier of the corresponding 3D component.

[0037] In an optional embodiment of the present invention, step S300 includes the following process: S310, determining the three-dimensional model component corresponding to each node identifier from the three-dimensional design component library according to the node identifier of each node, and determining the spatial attributes of the corresponding node accordingly.

[0038] In an optional embodiment of the present invention, for each node, determining the 3D model component corresponding to the node identifier from the 3D design component library based on the node identifier, and determining the spatial attributes of the corresponding node accordingly includes the following process: Based on the node identifier, determining whether there is a 3D component corresponding to the node identifier in the 3D design component library; if there is a 3D component corresponding to the node identifier, reading the geometric coordinates, direction vector, and component identifier of the 3D component in the model coordinate system, and converting the geometric coordinates into global spatial coordinates based on a preset coordinate transformation matrix, and using the global spatial coordinates, direction vector, and component identifier as the spatial attributes of the node; if there is no 3D component corresponding to the node identifier, re-determining its corresponding spatial attributes based on the next node, until all nodes have been processed.

[0039] Specifically, for each node, the following processing can be performed: The node identifier is read, and a matching query is performed in the 3D design component library to determine if a 3D component corresponding to the node identifier exists in the library. If the query result shows that a corresponding 3D component exists, the geometric coordinates, component orientation vector, and component identifier of the component in the model coordinate system are read. Based on a preset coordinate transformation matrix, the geometric coordinates are converted into global spatial coordinates, thereby obtaining the actual spatial position of the node in the overall coordinate system of the factory. After obtaining the global spatial coordinates, the global spatial coordinates, component orientation vector, and component identifier are uniformly used as the spatial attributes of the node for subsequent construction of node spatial information. Here, the geometric coordinates are used to characterize the specific spatial position parameters of the 3D component in the model coordinate system, the component orientation vector is used to describe the orientation characteristics of the component in 3D space, the component identifier is the unique marker information identifying the component in the 3D design component library, and the global spatial coordinates are the position coordinates in the global coordinate system of the factory obtained by mapping the geometric coordinates through the model-to-factory coordinate transformation matrix. 3D components are the fundamental objects in a 3D design model, corresponding to physical entities such as cable trays, equipment, and supports in a real factory. They possess independent geometric shapes, spatial attributes, and topological relationships within the model. If a 3D component corresponding to the current node identifier does not exist in the 3D design component library, that node is skipped, and the process continues to the next node in the path until the spatial attributes of all nodes in the path have been extracted. By retrieving and extracting spatial attributes one by one based on node identifiers, existing 3D design models can be fully utilized, achieving high-precision acquisition of node spatial information.

[0040] In another optional embodiment of the present invention, if there is no three-dimensional component corresponding to the node identifier, after all nodes have been processed, the method further includes: for each node that does not have spatial attributes, perform the following interpolation processing as the current node: interpolate the global spatial coordinates of each node adjacent to the current node to generate the global spatial coordinates of the node; generate the direction vector of the current node based on the direction vectors of each node adjacent to the current node, and use the generated global spatial coordinates and direction vector as the spatial attributes of the current node.

[0041] Considering that some nodes' corresponding 3D components are not modeled in the 3D design component library, directly ignoring these nodes would lead to breaks or discontinuities in the final generated cable path. To improve this, this invention infers the position and orientation of the current node based on the spatial attributes of adjacent nodes for nodes whose spatial attributes cannot be obtained from the 3D design component library, ensuring the integrity and continuity of the path. Specifically, nodes adjacent to the current node are selected, and their global spatial coordinates are read. Adjacent nodes refer to a predetermined number of nodes immediately before or after the current node in the cable path sequence, such as the previous or next node. The global spatial coordinates of these adjacent nodes are interpolated, and the interpolation result is used as the current node's global spatial coordinates in the 3D factory scene. Furthermore, based on the direction vectors of adjacent nodes, the current node's direction vector is obtained through vector averaging or direction interpolation to ensure that the node's spatial orientation is consistent with its preceding and following adjacent nodes. The interpolated global spatial coordinates and direction vector are used as the current node's spatial attributes, thus forming complete node spatial information. The above method allows the corresponding nodes to still be integrated into the overall cable path 3D trajectory generation process even if the 3D component model is missing.

[0042] S320. The spatial attributes of each node are processed in a structured manner to generate the node spatial information corresponding to the node.

[0043] After obtaining the spatial attributes of each node, these attributes are structured and encapsulated to generate node spatial information corresponding to each node. Node spatial information refers to structured data units that characterize the spatial position, orientation, and mapping relationship between the node and the 3D design model within the 3D factory scene. This includes, but is not limited to, the node's global spatial coordinates, direction vector, corresponding 3D component identifier, and other optional spatial metadata. Through structuring, scattered spatial attributes can be integrated into data with a unified format, clear type, and the ability to be processed by subsequent algorithms. Specifically, the spatial attributes of each path node can be standardized, unifying the expression format of each field. The global spatial coordinates, direction vector, and component identifier are encapsulated according to a preset data format, thereby generating a unique data record entry for each node, which serves as the node's spatial information.

[0044] S400. Arrange the spatial information of each node in sequence according to the corresponding node arrangement order to generate cable path spatial information used to characterize the cable path.

[0045] Specifically, after generating the spatial information of each node, all node information can be sequentially arranged according to their position in the cable laying sequence to form cable path spatial information representing the entire cable laying route. Cable path spatial information refers to an ordered data set formed by multiple node spatial information based on their path sequence, describing the spatial orientation, path shape, and spatial connection relationships between nodes in the 3D factory scene. By sequentially arranging the spatial information of each node according to their order, the actual laying sequence of the entire cable, from the starting equipment, through multiple cable tray sections and joint nodes, to the ending equipment, can be completely preserved, ensuring that subsequent 3D visualization results match the actual laying path.

[0046] In an optional embodiment of the present invention, the node spatial information includes the global spatial coordinates, direction vectors, and component identifiers of the nodes in a preset three-dimensional model. Step S400 includes the following processes: connecting the global spatial coordinates of adjacent nodes according to the arrangement order of each node to generate a spatial line segment sequence for representing the node order; smoothing the spatial line segment sequence based on the direction vectors of adjacent nodes to generate a continuous spatial path trajectory; associating the spatial path trajectory with the component identifiers of each node it includes to generate cable path spatial information for representing the cable path.

[0047] Specifically, since each path node corresponds to a node spatial information, which includes the node's global spatial coordinates, direction vector, and component identifier in a preset 3D model, the global spatial coordinates of each node can be connected one by one according to the order of the nodes in the path to form a spatial line segment sequence that can represent the order of cable laying. Furthermore, the spatial line segment sequence can be smoothed based on the direction vectors of adjacent nodes to make the generated path trajectory more continuous and natural, avoiding abrupt changes in the path. Preferably, in an optional embodiment of the present invention, the smoothing process is B-spline smoothing. By continuously fitting multiple node direction vectors, a smoother spatial path trajectory that conforms to the actual laying characteristics can be obtained. After generating a continuous spatial path trajectory, the trajectory is associated with the component identifiers corresponding to the path nodes, so that each segment of the spatial path can establish a mapping relationship with its corresponding bridge structure component or equipment component, ensuring the consistency between the spatial data and the 3D design model. The smoothed continuous spatial path trajectory and its corresponding component identifier are encapsulated as cable path spatial information, used to comprehensively represent the actual laying path of the cable in a 3D factory scene.

[0048] S500 performs visualization processing on the spatial information of the cable path and generates a visualization display result.

[0049] In an optional embodiment of the present invention, the cable data includes multiple cable sub-data, each cable sub-data corresponding to the laying status of a cable. Step S500 includes the following process: based on a preset display strategy, selecting target cables corresponding to the display strategy from the cable data; and generating a visualization display result of the cable path corresponding to the display strategy based on the cable path spatial information of the target cable.

[0050] The cable data consists of multiple cable sub-data sets, each corresponding to the laying status of a single cable and including its spatial path information. To achieve 3D visualization effects tailored to different display needs, target cables matching a preset display strategy can be selected from all cable data. Based on the spatial path information of these target cables, the required 3D visualization results are generated according to the display strategy. During generation, based on the cable path spatial information, a complete 3D display scene is constructed by loading the spatial path trajectory of the target cable, its associated bridge components, and equipment components. The cable is then rendered according to the requirements of the display strategy to generate the final visualization result.

[0051] In an optional embodiment of the present invention, when the display strategy is to display a single cable, the step of generating a visualization display result of the cable path corresponding to the display strategy based on the cable path spatial information of the target cable includes: generating a three-dimensional geometric model corresponding to the target cable based on the cable path spatial information of the target cable; loading the cable tray model and equipment model corresponding to each node from a preset three-dimensional spatial model library based on the node name of each node; and combining and rendering the three-dimensional geometric model with the corresponding cable tray model and equipment model to generate a three-dimensional visualization display result of the target cable.

[0052] When the display strategy is for a single cable, a 3D visualization result is generated based on the spatial information of the cable path corresponding to the target cable. Specifically, based on the spatial information of the target cable's path, a 3D geometric model corresponding to the cable is constructed according to the path trajectory and node position relationships to represent the actual route of the cable in 3D space. Then, based on the node names contained in the path nodes, the corresponding cable tray models are loaded from a pre-set 3D space model library. After loading the cable tray model, the starting and ending equipment corresponding to the target cable are loaded, thus establishing a mapping relationship between each node in the cable path and its actual 3D components. The generated 3D geometric model of the cable is combined and rendered with the loaded cable tray and equipment models in the same 3D scene to form a complete 3D visualization result for a single cable, thus intuitively reflecting the actual laying path of the cable in the factory and its spatial relationship with surrounding components. Understandably, the single-cable display strategy does not limit the number of target cables. When the display strategy is single-cable display and multiple target cables are obtained after filtering, the above-mentioned single-cable visualization generation process can be performed on each target cable in turn according to the order of the target cables, and the corresponding single-cable 3D display results can be generated respectively.

[0053] In another optional embodiment of the present invention, when the display strategy is system-wide display, the step of generating a visualization display result of the cable path corresponding to the display strategy based on the cable path spatial information of the target cable includes: for each target cable corresponding to the system: generating a three-dimensional geometric model corresponding to the target cable based on the cable path spatial information of the target cable; loading the corresponding cable tray model and equipment model from a preset three-dimensional spatial model library based on the node names of each node in the cable path spatial information of the target cable; combining and rendering the three-dimensional geometric model of each target cable with the corresponding cable tray model and equipment model, and displaying different target cables in different colors to generate a visualization display result of the cable path under the system scope.

[0054] When the display strategy is system-wide, all target cables corresponding to the system will be used as objects, and a 3D visualization display covering the entire system will be generated based on the cable path spatial information. Specifically, each target cable within the system will be traversed, and a corresponding 3D geometric model will be generated based on the cable path spatial information to describe the actual laying trajectory of the cable in the 3D factory scene. For each target cable: based on the node name contained in the node spatial information of the target cable, the cable tray model corresponding to each path node will be loaded from a preset 3D spatial model library. After the cable tray model is loaded, the starting and ending devices of the target cable will be loaded, so that all cable tray sections, joint positions, and starting and ending devices traversed by the target cable within the system scope can be accurately presented in the 3D scene. After the above geometric model and scene components are loaded, the 3D geometric models of all target cables within the system scope, along with their corresponding cable tray models and equipment models, will be combined and rendered in a unified global spatial coordinate system. Furthermore, to facilitate the differentiation of different cables in the system, each target cable will be displayed in different colors, making the spatial relationships and laying coverage of the cables clearly visible. The final system-wide visualization results can fully present the three-dimensional laying path of all cables within the system, providing more intuitive reference information for system-level design verification, fault diagnosis, and operation and maintenance management across cables and regions.

[0055] In another optional embodiment of the present invention, when the display strategy is to display the factory area, the step of generating a visualization display result of the cable path corresponding to the display strategy based on the cable path spatial information of the target cable includes: for each target cable corresponding to the factory: generating a three-dimensional geometric model corresponding to the target cable based on the cable path spatial information of the target cable; loading the corresponding cable tray model and equipment model from a preset three-dimensional spatial model library based on the node names of each node in the cable path spatial information of the target cable; loading the three-dimensional factory background model corresponding to the factory from the background model library based on the factory's identifier; and globally combining and rendering the three-dimensional geometric model of each target cable with the corresponding cable tray model, equipment model, and three-dimensional factory background model to generate a visualization display result of the cable path within the factory area.

[0056] When the display strategy is to showcase the entire factory area, the visualization generation process includes: for each target cable corresponding to the factory area, generating its corresponding 3D geometric model based on the cable path spatial information. Based on the node names contained in the node spatial information of the target cable, loading the corresponding cable tray model from a pre-set 3D spatial model library. After the cable tray model is loaded, loading the starting and ending devices of the target cable. After all target cables are processed, loading the corresponding 3D factory background model from the background model library based on the current factory area's identifier. After loading, the 3D geometric models of each target cable, its corresponding cable tray and equipment models, and the 3D factory background model are globally combined and rendered in a unified coordinate system. This allows the laying paths of all target cables within the factory area to be centrally displayed in the complete 3D factory scene, thus generating a visualization display result of the cable paths within the factory area.

[0057] In an optional embodiment of the present invention, after generating the visualization result of the cable path within the factory area, the method further includes: responding to the visible area of ​​the current camera, dynamically loading a three-dimensional factory background sub-model corresponding to the current visible area from the three-dimensional factory background model.

[0058] Specifically, in response to the current viewport area, a 3D factory background sub-model corresponding to the current viewport area is extracted from the 3D factory background model, and this sub-model is dynamically loaded into the rendering scene as needed. When the camera angle moves or the viewport changes, the previously loaded background sub-model can be unloaded or replaced according to the updated viewport area, thereby achieving localized and on-demand loading of the 3D factory background model to reduce the rendering load and improve the real-time visualization performance of the factory-level scene.

The cable data acquisition module 210 acquires cable data to characterize the cable laying status. The path parsing module 220 parses the path information of the cable data to obtain multiple nodes arranged in path order; the path information describes the cable path. The node parsing module 230 extracts the node spatial information corresponding to each node; the node spatial information characterizes the spatial position and orientation attributes of the corresponding node in the 3D scene. The path generation module 230 arranges the node spatial information sequentially according to the corresponding node arrangement order to generate cable path spatial information characterizing the cable path. The visualization module 240 performs visualization processing on the cable path spatial information to generate a visualization display result.
