Design And Implementation Of 3D Visualization Management System For Wind Farm Maintenance

The 3D visualization is a representation of data,it is a means to describe and understand a model.It can change the computer generated data in the process of operation or the actual measurement of data and information into a graphical image expressed in time and space changes in physical phenomena or physical quantities,make them more intuitively presented.In recent years,the development of wind power industry in China is very rapid and the number of wind farms is increasing.With the acceleration of the construction of wind power generation,higher requirements are put forward for the construction and maintenance management of wind farms.Some traditional data visualization techniques and man-machine operation and maintenance management methods can no longer meet the current needs the 3D visualization of wind farm management becomes more important.Aiming at the three dimensional visualization and data display platform of wind farm maintenance,this paper is divided into six modules:user login registration,3D Earth display,wind farm distribution display,equipment management,duty table management and system management.The 3D Earth display module of digital earth technology based on osgEarth,realized in the process of three-dimensional model of the earth zoom,including the provincial,municipal as well as multi-level highway rail geographic information vector data hierarchical display,Offline terrain LOD display,wind farm 3D scene display,wind farms 3D multi-mode scene roaming,equipment maintenance status display,wind farm three-dimensional scene automatic generation and other functions.The wind through the automatic generation of 3D wind farm processing user input of longitude and latitude,type and quantity,fan type interval,the prevailing wind direction and other parameters,the automatic generation of wind farm 3D scene,improve the efficiency of 3D scene modeling of wind farm.The system is based on B/S(Browser/Server)architecture,combined with osgEarth 3D rendering engine and JavaEE technology framework,and Embed osgEarth into browser to realize 3D visualization management of wind farm maintenance.This system provides wind 3D scene display function,which can directly reflect the geographic location of the wind farm,the damaged equipment and the like.At the same time,it provides a more effective management of maintenance and maintenance data of wind farm during operation,which can enhance the efficiency of maintenance and management of wind power business of wind power equipment.
