Study On Visualization Of Underground Power Pipelines Based On Virtual Reality

Power line is an important part of the infrastructure,is the lifeline of the city,which is responsible for homes is transmitted light and energy,is the guarantee of economic development and normal production and living of the people important support.In recent years,with the pace of urban construction is accelerated,the surge of load capacity and load density,urban power infrastructure gradually transferred to the underground construction,combined with the power line number increases year by year,the current means of power line management to keep pace with the needs of the development of the electric power line power line planning management problem increasingly prominent.The current national construction of underground power pipeline is mainly with PVC casing wire and cable,casing pipe and wire and cable of traditional management method using Excel mutual combination of AutoCAD software,by AutoCAD trend of casing and wire and cable,section drawing,fill in the data file in Excel.This method has many disadvantages:visual is not high,difficult to maintain,low reliability database information,etc.So easy to cause the lack of underground power pipeline database and management error,a potential hazard to safe and effective operation of power grids,mainly reflected in two aspects:(1)the lack of system of complete sets of underground power pipeline present status;(2)the lack of a flexible and reliable information technology on the system of business management.To solve the above problems,this paper studies a set of underground power line 3 d visualization system.In the first place and the function of the system architecture is analyzed,and the electric power network in detail the function of the database structure design,put forward the integration of spatial data and attribute data storage way,according to different usage of underground electric power line,the electric power network data for the organization and classification,make the system of the query and retrieval efficiency is improved.Second,the research analysis of VR,GIS theory and the theory on the basis of 3 d model visualization,three-dimensional visualization technology is analyzed,and use in detail elaborated the system institute of OpenGL 3 d visualization technology,for which lay a theoretical foundation for 3 d modeling of the power network.Moreover,through the description of the 3 d spatial data model and analysis of the characteristics of the electric power network data structure,the design of pipe network concept model and organization model,on the basis of the realization of the 3 d virtual scene modeling method and the principle of network modeling and to abstract and simplify the electric power network data,through the space position of the electric power network 3 d model and surface geometric composition analysis,the study section model algorithm and pipeline inflection point model algorithm,puts forward reasonable formula,based on OpenGL 3 d visualization technology to build the pipeline model mapping algorithm code,setting the underground power network 3 d virtual scene model has obtained the good effect.Finally through the development of 3 d power pipeline visualization system,effective implementation of the management of underground electric power line,quick grasp the power line construction and usage,reduce the investment of the construction of the waste in the future.In this paper,the underground electric power line 3 d visualization based on virtual reality system for power network information system research to explore a new way,for the future power network of scientific management and decision provides an important theoretical value.
