Problems solved by technology

[0004] The main problem brought by the current popular 3D modeling technology and modeling method is that the 3D model is integrated, and loading the 3D model into the 3D GIS system can only be transformed as a whole and cannot be adjusted separately for each component of the equipment. One of the main problems brought about by this phenomenon is that a complete set of models must be re-established for each different power equipment. Remodeling will increase the workload and make it difficult to modify the model

Embodiment Construction

[0026] Such as figure 1 Shown, the present invention comprises the following steps:

[0027] ① Decompose the transmission tower into several power components, and use object-oriented technology to classify the decomposed power components according to the national grid power equipment standard. The classification method is a tree-structured electrical equipment classification method. Device attribute information, and then identify the electrical components to obtain device identification information.

[0028] When classifying power components, it is considered that in the virtual scene of power grid construction and operation based on 3D GIS technology, because the topological relationship between the power grid and its equipment has changed from traditional two-dimensional to three-dimensional, and from plane to three-dimensional, the power grid monitoring Logical relationships also have new features. In the three-dimensional power grid information monitoring system, not onl...

Abstract

A power transmission iron tower three-dimensional virtual assembly method includes following steps: 1, discomposing a power transmission iron tower into a plurality of power components, classifying the power components after decomposing by adopting the object oriented technology according to state grid power equipment standards to obtain equipment attribute information of the components, and then identifying the power components to obtain equipment identification information; 2, correlating the equipment attribute information with the equipment identification information of the power components, and creating a three-dimensional component type power equipment model by adopting the three-dimensional modeling technology to obtain a three-dimensional power equipment component model database; 3, establishing a power transmission iron tower assembly relationship data model according to spatial configuration and assembly relationship among the power components; and 4, performing virtual assembly to the three-dimensional component type power equipment model according to the established power transmission iron tower assembly relationship data model to obtain a complete power transmission iron tower three-dimensional model.

Description

technical field [0001] The invention relates to a virtual assembly method for equipment, in particular to a three-dimensional virtual assembly method for power transmission towers. Background technique [0002] In recent years, 3D GIS technology has developed vigorously, and breakthroughs have been made in large-scale terrain display, spatial data management and spatial data analysis. As the basis of 3D visualization in the electric power industry, 3D modeling technology has been extensively researched and applied. However, the traditional 3D modeling technology has the characteristics of integration. In the design and management application of power equipment in the power industry, using traditional modeling methods for each power equipment will bring heavy workload and difficult model modification. . Based on the three-dimensional GIS platform, the present invention realizes the component-type three-dimensional fine modeling and assembly process of electric power equipme...
