Research On Human-computer Interaction System Of3D Electromagnetic Field Forward And Inversion

Magnetotelluric sounding method is an important geophysical method used for study ondetection and continental dynamics of the deep electrical structure, has been more and morewidely used in energy exploration, engineering application and prevention of natural disasterareas. At present, the one-dimensional, two-dimensional magnetotelluric inversion technologyis already quite mature, with the development of computer performance and high performancecomputing technology promotion,the three-dimensional magnetotelluric inversion calculationpreviously limited to speed has entered a practical stage. At present, the magnetotelluricsoftware mainly is the monopoly of the Foreign Company. In the actual operation process of3D electromagnetic field inversion, the need for Electromagnetics model construction and theimportant parameters for visual display, the traditional way is through the method of manualor automatic drawing section map, contour map to show the detected data, these methodsoften have defects sush as data display is not comprehensive, the effect is not directviewing,because of the limit of personal computer performance, executing inversion proceduretime-consuming there are also unable to meet the performance requirements.In this paper, in order to overcome these shortcomings, designed and implemented athree-dimensional magnetotelluric forward and inversion system, this system combines thetwo-dimensional data map and3D visualization technology, can make the user convenientlyon data browsing, data editing, better3D modeling and Realization of3D data and modelresults. Using client/server architecture, the data will be uploaded to the server computingand return results, can greatly reduce the time-consuming inversion procedure, and reduce thecalculation of the pressure on the local machine. The program has the advantages ofconvenient operation, simple and efficient, quick and easy,has beautiful graphics, strongpracticability, can meet the user modeling system of3D magnetotelluric forward andinversion requirements. This system uses the software engineering process, detailed document.This paper expounds the system from requirements analysis, design to implementation and operation of the entire process, including the flow chart of software engineering, the classdiagram, interaction diagram of all kinds, graphical design.Using Qt Integrated DevelopmentEnvironment to complete the development of client,using socket to complete the developmentof the communication between client and server. Finally a practical example in the practicalexploration in the display system.
