Abstract


Communication vehicle mounted electronic devices become more intensive , which triggered the harsh electromagnetic environment will seriously affect the normal operation of equipment , equipment rooms will have a serious of MAI . Electromagnetic compatibility between devices prediction has become resolved an important means of electromagnetic interference problems , the predicted results will provide scientific and reasonable frequency management basis . In this paper, electromagnetic compatibility analysis theory, first established based on three factors predicted electromagnetic compatibility analysis of research ideas , to be launched device that is the source of interference , the receiving device that is sensitive equipment , antennas and propagation space that is coupled pathway . Second, in -vehicle communications system to fully understand the principles established on the basis of site -vehicle communication system interference model , and on this basis, combining the three elements of the electromagnetic compatibility of MAI further establish a model transmitters, receivers and coupling channel math model . Then the analysis of the sending and receiving devices coupled interference based on the principle , was established by the sending and receiving devices effective method of coupling and interference obtained several common interference level is calculated as well as interference bandwidth analysis and electromagnetic compatibility -parameter analysis. In order to inter- vehicle communication system electromagnetic interference for fast, comprehensive and effective predictive analysis , based on Oracle established for the frequency analysis of electromagnetic compatibility tube sound basis for rational database , detailing each sub- library database structure design and functional design . Finally, based on VC 6.0 wrote some predicted electromagnetic compatibility analysis and simulation software, simulation software for the design and use of the interface is described in detail .
