[0002] In the power industry, the construction and maintenance of transmission projects are the main components to ensure the stable operation of the power system. Modeling and simulation technology of transmission projects plays an increasingly important role in engineering design, construction, operation and maintenance. However, traditional transmission project modeling methods often have problems such as low data analysis efficiency, insufficient model accuracy, and slow loading speed, which cannot meet the needs of modern power systems for efficient and accurate modeling.

[0003] At present, power transmission projects use GIM for digital modeling in engineering design. The GIM model contains rich information about power transmission equipment. However, when using the GIM model to design and load power transmission equipment such as towers, due to the relatively complex structure and the need to combine actual conditions and design requirements, a large amount of data will be extracted or processed. Directly loading and processing a large amount of data often leads to low efficiency, and even data loss or errors.

All vertices of the mesh are traversed, and the distance between the reference point and the vertex is calculated to determine whether to delete it. If the distance is greater than a given threshold, the vertex is deleted and a simplified off model is output; After the model is assembled, the OpenMesh library vertex clustering algorithm is used to simplify the mesh, merge the vertices in the same voxel, and reconnect the facets based on the clustered vertices.

[0010] It should be further explained that, in step S103, the top block space is divided into eight equal regions using the octree algorithm, and the data are stored in each region space according to the region where the GIM model of the power transmission project is located, and then the data of each region space is recursively divided downward in turn through a given maximum recursion depth until the octree depth reaches the maximum recursion depth; According to the distance of the GIM model of the transmission project, the data is reorganized and the display accuracy of the data is adjusted, the slice data is divided and output in three file formats: b3dm, i3dm and cmpt, so as to construct a model file based on 3dtiles standard data.

[0011] It should be further explained that step S104 also includes: by parsing the model file, recording the engineering model file whose ENTITYNAME attribute is F4System, and then recording the BLHA of the TOWER type and the POINT.BLHA and POINT.MATRIX of the WIRE type respectively according to the GROUPTYPE type, that is, obtaining the position information and azimuth of the tower, as well as the insulator hanging point position and spatial posture matrix; Parse the CBM engineering model with GROUPTYPE type CROSS to obtain the location information of the crossing objects.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] See also Figure 1 The figure is a flow chart of a method for analyzing and loading a GIM model of a power transmission project in a specific embodiment, the method comprising: S101: Acquire a GIM model of a power transmission project, and extract and parse the graphic data of a tower group in the GIM model of the power transmission project.

[0025] In some embodiments, a pre-stored power transmission project GIM model may be obtained from a database: the power transmission project GIM model includes three-dimensional graphic data and attribute information of equipment such as tower groups, ground wires, and substations of the power transmission and transformation project.

[0026] In this embodiment, the three-dimensional modeling software can be used to locate the pole tower group part, and the three-dimensional graphic data of the pole tower group can be extracted by selecting or filtering functions, that is, the pole tower group graphic data is extracted. The extracted pole tower group graphic data is analyzed, including the model, size, material, position coordinates and other information of the pole tower, and the specific pole tower related data can be analyzed according to the actual design needs.

[0027] This embodiment uses the GIM model of power transmission engineering to parse the tower group graphic data in the GIM model, meeting the requirements of tower equipment design, simplified processing, three-dimensional model generation, and extracting relevant data according to design needs.

[0028] In some specific embodiments, the power transmission project GIM model contains power transmission project GIM standard format file data, that is, the power transmission project GIM standard format file data is stored in the database.

[0029] The data stored in the transmission project GIM standard format file include: geometric model unit (*.mod), combination model (*.phm), physical model (*.dev), logical model (*.sch), engineering model (*.cbm) and attribute information (*.fam). The standard format file stores data in four directory structures: CBM, DEV, PHM and MOD. The file uses GUID as the unique identifier. All files are uniformly encoded in UTF-8. The standard format file establishes the relationship between each level through reference.

[0030] This embodiment also manages the engineering GIM model hierarchy and can divide the GIM model data into five levels, starting from level 1 full-line level, level 2 segment level, level 3 tension section level, level 4 equipment group (pole tower group, conductor group, crossing group) level, and level 5 material, equipment, and facility level to extract attribute information and perform parametric modeling of basic graphics elements.

[0031] For example, the GIM model of the transmission project has a project.cbm file, which is traversed and parsed in sequence from level 1 full-line level to level 5 material, equipment, and facility levels according to the reference relationship. The parsed basic graphics elements such as tower group sub-equipment and conductor group sub-equipment are parametrically modeled using the OpenMesh library. The equipment group level assembles and spatially transforms the parametric model tower itself, tower legs, insulators, etc. through the reference relationship to obtain a complete equipment group model, and converts it into the standard FBX data format based on the FBX SDK; the parsed attribute data such as tower hanging points, tower postures, crossing objects, etc. are stored in the form of sql files.

[0032] S102: Simplify the graphic data of the tower group according to different levels, and output the simplified results as a three-dimensional model.

[0033] In some embodiments, the tower group graphic data is divided into different levels according to its complexity and display requirements. For example, the overall structure of the tower can be divided into the top layer, and the detailed parts on the tower (such as insulators, hardware, etc.) can be divided into the bottom layer.

[0034] This embodiment simplifies the graphic data of each level. For the top-level data, its overall outline and top-level features can be retained; for the bottom-level data, it can be configured according to the design requirements.

[0035] The method for simplifying the tower in this embodiment includes reducing the number of polygons, merging similar geometric bodies, optimizing texture mapping, etc.

[0036] The simplified graphic data is output as a 3D model file and then saved. The simplified 3D model in this embodiment can improve the loading and rendering efficiency and user experience, and facilitate the subsequent slicing and spatial layout.

[0037] As a preferred method of this embodiment, when parametric modeling is performed on pole towers and insulators, the built-in PolyMesh_ArrayKerneIT triangular mesh class is used through the OpenMesh library to construct a mesh body according to the parameterization, and the center point of the mesh body is used as the reference point to traverse all the vertices of the mesh. The distance between the reference point and the vertex is calculated to determine whether to delete it. If the distance is greater than a given threshold, the vertex is deleted and the simplified off model is output. After the model is assembled, the OpenMesh library vertex clustering algorithm is used to further simplify the mesh, merge the vertices in the same voxel, and reconnect the facets based on the clustered vertices to achieve the effect of simplifying the mesh.

[0038] S103: Slice the 3D model in fbx format to form a model file.

[0039] In some embodiments, the simplified FBX format 3D model is imported into the slicing processing software, and the slicing processing software can use existing software, such as 3D Slicer slicing processing software. In the slicing processing software, the pole tower slicing parameters are set, such as the pole tower slicing direction, the pole tower slicing thickness, the number of pole tower slicing, etc. Setting the parameters for the pole tower can generate the slicing effect and quality of the model file.

[0040] Slice the 3D model according to the set slice parameters. The slicing software will cut the model into multiple thin layers and save each layer as a model file. Export the sliced ​​model file to the required format.

[0041] S104: Extracting status information of tower equipment in the model file.

[0042] In this embodiment, the state information of the pole tower equipment is extracted from the parsed data. The parsed data information includes, but is not limited to, parameters such as the inclination angle, stress condition, foundation information, and usage status of the pole tower. The method of extracting the state information includes measuring the change of geometric shape, analyzing the change of material properties, etc. The extracted state information is recorded in a database or storage medium.

[0043] S105: Parsing and exporting the tower equipment attribute information in the power transmission project GIM model in the form of an SQL file.

[0044] In this embodiment, the tower equipment attribute information in the GIM model of the power transmission project is parsed. Specifically, it includes the model, size, material, etc. of the tower. According to the parsed attribute information, the structure of the SQL file is constructed. The structure of the SQL file may involve defining data tables, fields, and data types, etc. The parsed attribute information is organized according to the structure of the SQL file and exported as an SQL file. It can be used to import and store data in a database management system. Improve the efficiency and accuracy of data management.

[0045] S106: Arrange the pole tower equipment in three dimensions to form the shape of the transmission line.

[0046] In one implementation of this embodiment, the position coordinates of each pole tower device in three-dimensional space are determined according to the design requirements and actual conditions of the power transmission project. In three-dimensional modeling, instances of pole tower devices are created based on the pole tower group graphic data obtained by previous parsing and simplification. These instances will be used for subsequent three-dimensional space layout. The created pole tower device instances are arranged according to the determined position coordinates. In the arrangement process, factors such as the relative position relationship between the pole tower devices and the direction of the transmission line need to be considered.

[0047] For the construction of the transmission line form involved in this embodiment, after the pole tower equipment is arranged, according to the design requirements and actual conditions of the transmission line, the pole tower equipment can be connected using components such as conductors and ground wires to form the form of the transmission line. This embodiment can display the form and layout of the transmission line through three-dimensional space arrangement for designers to view and use, and can optimize the design of the three-dimensional model of the pole tower during the design process.

[0048] S107: Analyze the positions of the ground wire and the hanging ground wire in the GIM model of the power transmission project, and store the key point data of the ground wire.

[0049] In this embodiment, the location information of the ground wire and the hanging ground wire is parsed from the GIM model of the power transmission project. The location information includes but is not limited to the starting point, end point, path coordinates, etc. of the ground wire and the hanging ground wire. According to the parsed location information, the key point data on the ground wire is extracted. The key point data includes the turning point, fixed point, connection point, etc. of the ground wire. The extracted key point data of the ground wire is stored in a database or other forms of storage media.

[0050] S108: Based on the spatial range control model, the loading range of the three-dimensional model, the grounding wire and the hanging grounding wire and the visible height of the three-dimensional model are set.

[0051] In some embodiments, a three-dimensional spatial range control model is constructed according to the actual geographical environment and design requirements of the power transmission project. The three-dimensional spatial range control model can define the boundary and range of the power transmission project in three-dimensional space. Within the spatial range control model, the loading range of the three-dimensional model, the ground wire, and the hanging ground wire is determined according to actual needs. The loading range can be a fixed area or can be dynamically adjusted according to the user's perspective or operation.

[0052] According to the actual situation and design requirements of the power transmission project, the visible height of the 3D model in 3D space is set. The visible height is configured according to the actual design scheme to meet the design requirements of the tower.

[0053] In the 3D modeling software, the loading and rendering control of the 3D model, ground wire and ground wire can be realized according to the set loading range and visible height. Specifically, it can include loading model files, rendering models, adjusting viewing angles and other operations.

[0054] This embodiment can optimize the loading and rendering performance of the three-dimensional model by setting the loading range and visible height, so that the design of the tower meets the requirements.

[0055] In the GIM model analysis and loading method for power transmission engineering involved in the present application, further processing is performed after simplifying the three-dimensional model of the result output. The following will be an extension of the specific implementation method of the above embodiment to provide another preferred implementation method, such as Figure 2 As shown, the specific implementation process in this embodiment is fully described below.

[0056] S301: The top block space is divided into eight equal regions using the octree algorithm, and the model data is stored in each region space according to the region where the model is located. Then, through a given maximum recursive depth, the spatial data of each region is recursively divided downward in turn until the octree depth reaches the maximum recursive depth.

[0057] This embodiment reorganizes the data and adjusts the display accuracy of the data according to the distance of the model. The divided slice data is output in three file formats: b3dm, i3dm and cmpt. The model's hierarchical structure and slice data scheduling relationship are output in tree structures in scenetree.json and tileset.json files, respectively, to construct 3dtiles standard data results. After the result data is published online, a three-dimensional data service with sharing capabilities can be constructed.

[0058] S302: Extracting spatial location information of equipment in the GIM model of the power transmission project.

[0059] Based on the analysis of the GIM model graphic data and attribute data in step S101, the CBM engineering model file is analyzed, and the engineering model file with the ENTITYNAME attribute of F4System is recorded. According to its GROUPTYPE type, the BLHA of TOWER type and the POINT.BLHA and POINT.MATRIX of WIRE type are recorded respectively, so that the location information and azimuth of the tower, as well as the location and spatial pose matrix of the insulator hanging point can be obtained. Similarly, the location information of the crossing object can be obtained by analyzing the CBM engineering model with the GROUPTYPE type of CROSS.

[0060] S303: Extracting attribute information of the tower equipment of the GIM model of the power transmission project.

[0061] Based on the extraction of the spatial information of the GIM model equipment, this embodiment searches for the CBM file referenced by its ontology through the GROUPTYPE type, parses the referenced CBM file and records the content of the BASEFAMILY field, that is, the name of the FAM attribute file.

[0062] This embodiment parses the FAM attribute file to obtain device attribute information, and uses a SQL file to record the attribute information of the tower, conductor and crossing object and the corresponding model file name in a library table, retaining the correspondence between the structured attribute information and the graphic information to support the three-dimensional platform side view attribute query capability.

[0063] S304: Based on the results of step 3 and step 4, the processing results of the pole tower equipment group are arranged in three-dimensional space to form the basic form of the line, and the attribute information is stored in the database to realize the construction of graphic query capability of the pole tower group equipment.

[0064] S305: Draw the ground wire in the three-dimensional scene according to the endpoint position, key point position and other data of the ground wire, use yellow, green, red and gray to render and color the conductors (Phase A, Phase B, Phase C) and the ground wire, organize and store the drawing results in the format of vector data, and publish them as data services that can be loaded by the three-dimensional platform.

[0065] S306: Control the content and display strategy of the model loading according to the spatial range, and control the loading of the model and vector lines according to the height and the spatial range around the viewpoint.

[0066] The viewing angle height and model automatic loading range of this embodiment are 1 km and 3 km respectively, and layer-by-layer loading is set during loading to reduce the amount of model data transmission. The rendering resources occupied by the three-dimensional model and vector data involved in this embodiment can be released in time to ensure the stability and smoothness of loading.
