Study on Filter Performance Optimization of Balise Transmission Unit
摘要
Abstract
In this paper,the research status of Electromagnetic Interference(EMI)of balise system in electromagnetic rail environment is summarized,and a scheme of optimizing the filter performance of balise transmission unit is put forward according to the common methods of EMI protection.Firstly,the filter performance of the existing balise transmission unit is analyzed,and a new filter circuit is designed by the traditional method.Then,the NSGA-Ⅱ algorithm is adopted to optimize the calculation scheme for the problem that the performance index of filter circuit obtained by traditional calculation method has deviation,and the equivalent filter circuit is realized after considering the transmission line and the actual components.After that,the parameters are optimized by software to reduce the influence of distributed parameters and the filter is produced.Finally,the insertion loss index of the filter is tested by spectrum analyzer,and the feasibility of the scheme is verified by comparing with the theoretical value in design.关键词
