Development Of Predictive Analysis Software Of Electromagnetic Compatibility For Vehicle Communication Systems

There are many electronic devices on vehicle communication system, whichleads to poor electromagnetic compatibility and affects the quality of thecommunication. Therefore, developing predictive analytics software of the EMC onvehicle communication system based on the predictive theory of EMC has importantvalue of engineering practice.Aiming at the characteristics of EMC and developing claims of the software on vehiclecommunication system, we analyzed the technical feasibility of building models ofvehicles, the degree of antenna coupling, the obstructing amount of equipment,transmitting antenna coverage, database management based on the softwarerequirements analysis firstly, and built the computing models. Meanwhile, we designedthe user interface layer, the business function layer and data support layer detailedusing general principles of software design. Then we designed the databasemanagement applying UML methods and USE-CASE graphs, and identified thedatabase table format and table design methods. It made the fundamental database ofvehicles, antennas, devices inside-system and electromagnetic environmental databaseof EMPs more reasonable and accurate. Finally, we stratified implement this softwareusing some key techniques such as template-instance, multi threads, STL, DLL,OpenGL and so on. Based on testing methods, we designed testing examples andevaluated its qualities. This work ensured the rationality of developing and thereliability of actual application.
