Design And Implementation Of Entity Data And Post-Process Module For EMC Simulation Platform

With the development of science and technology, more and more electronic equipmentare used in our daily life and production, which bring concern and problems ofelectromagnetic interference. As we all known, electromagnetic interference do fatal damageto electronic equipment. Electromagnetic Compatibility has been researched for about eightyyears, until now the most effective and important way to find and avoid problem ofelectromagnetic interference is using EMC modeling and simulation software in design stage.Kinds of EMC simulation software are developed to handle the problems of electromagneticinterference in foreign. In China, the focus of research is on electromagnetic algorithms, whilepretreatment and post-process modules are rarely researched. That’s the reason whyintegrated EMC simulation platform can’t be developed.The main contents of this paper are about designing and realizing the entity data and thepost-process module, which are parts of electromagnetic compatibility software of Warship.Modeling the research object accurately is the first and important step of EMC simulation,which is also the prerequisite and guarantee of getting correct simulated outcomes. Themechanisms are introduced to get the data to build the model and to make the data of createdmodel visually which can be modified to change the position and shape of the model, basedon mechanism of hybrid programming of ACIS and HOOPS. Huge data is created after thesimulation, the user will get the simulated outcomes by analyzing those data, which istime-consuming and inaccurate. Data visualization will make it easier and more accurate. Thedata can be displayed using technology of Windows graphics programming, TeeChart widgetand Matlab. After analyzing the advantages and disadvantages of the three methods of datavisualization, the hybrid programming of Matlab and VC++based on DLL method is chosenas the data visualization method in the software developing.2D data of simulated outcomesare displayed using geometric figures, while3D data are displayed using color matchingmethod. The technology of color index interpolation of HOOPS also researched to reflect the3D data to model to make the outcome more audio-visual.In the software, the function of getting modeling data and making the data of createdmodel visual is designed and realized under the mechanism of hybrid programming of ACIS and HOOPS. Post-process module is realized in the framework of HOOPS with the hybridprogramming of VC++and Matlab.
