Embodiment Construction

[0039] See figure 1 As shown, as an embodiment of the present invention, a three-dimensional GIS technology-based power grid visualization system includes:

[0040] The database further includes a first database storing three-dimensional geographic information, a second database storing data of power grid equipment, and a three-dimensional model file addressing information table (not shown in the figure), wherein the three-dimensional model file search The address information table stores the names of various models and the address information of their 3D model files. Various 3D model files are directly stored on the hard disk of the server. Various 3D models include 3D models of any type of objects contained in the scene, such as buildings. 3D models of, streets, transformer stations, telephone poles, etc.; when the server reads the model file, it needs to read the storage location of the predetermined model file from the three-dimensional model file addressing information table ...

Abstract

The invention relates to a three-dimensional GIS (Geographic Information System) technology based power grid visualization system and method. The three-dimensional GIS technology based power grid visualization method comprises the steps of: dividing models to be uploaded into different model upload sub-tasks based on different types of objects included in a scene to be uploaded, and calling model documents of the multiple sub-tasks in a parallel manner through a multi-thread way to improve an uploading speed; and meanwhile, on the basis of dividing the uploading tasks into different model uploading sub-tasks based on the type of the uploaded objects, only reading the model document of the objects of each type for once, wherein the repeated use of each model document is not limited to the uploading task of one client; and different clients can multiplex the read model documents. Therefore, the three-dimensional GIS (Geographic Information System) technology based power grid visualization system and method, disclosed by the invention, have the advantages of giving a full consideration to the characteristics of limited type and relative consistent specification of power devices, avoiding repeated reading of the model documents of the same type, obviously improving the uploading efficiency, guaranteeing rapid uploading and guaranteeing real-time browsing of the clients.

Description

Technical field [0001] The invention relates to a three-dimensional geographic information system, in particular to a power grid visualization system and method based on three-dimensional geographic information technology. Background technique [0002] GIS stands for Geographic Information System. Geographic Information System is based on geospatial database. With the support of computer software and hardware, theories of system engineering and information science are used to scientifically manage and comprehensively analyze geographic data with spatial connotations. , In order to provide technical systems for management, decision-making and other required information. Simply put, GIS is a technical system for comprehensively processing and analyzing geospatial data. It is based on surveying, mapping and measurement, using databases as data sources for data storage and use, and using computer programming as a platform for global spatial analysis real-time technology. [0003] With...
