系统间电磁兼容性预测分析软件的开发与研究
|
摘要
电子技术的飞跃发展,特别是通信技术的发展,使有限的空间电磁环境信号高度密集,电磁环境非常复杂。如何解决系统间电磁兼容性问题使电子设备在复杂环境中能够正常工作的有关系统间电磁兼容性问题已经受到越来越多的重视。
本文针对系统间电磁兼容性设计进行了下列探索性研究:
首先,从电磁干扰的三要素出发,详细分析系统间电磁干扰的机理,包括干扰发射机、被干扰敏感设备、天线和无线电波在各环境中的传播特性;结合电磁兼容标准规范建立相应的数学模型;采用分级筛选法对系统间电磁兼容性进行分析预测;总结出计算流程图。
其次,在理论推导的基础上,结合功能需求,详细规划各模块的结构,以Microsoft Visual Studio.NET 2005为开发平台,用C#开发了一套具有较强结构体系、易扩充、易维护、具有良好人机交互界面的“系统间电磁兼容性预测分析1.0”软件,软件内容包括七大模块,分别为:问题输入、数据采集、常用计算、传输损耗、干扰场强计算、系统间干扰分析和分析报告输出。编写过程中合理使用“模式”窗体与“无模式”窗体相结合。
软件设计编写完成之后,为了用户更好地使用该软件,编写了软件的帮助文档,对软件功能的使用做了部分演示说明,并提出使用过程中的注意点。
最后,结合相关文献对软件进行测试,证明该软件具有一定的适用性,对系统间电磁兼容性设计具有一定的指导作用。为今后国内研发出能够应用于实际的系统间电磁兼容分析软件做出了一些贡献。
With the rapid development of electronic technology, especial the dramatic development of communication, the limited space of electromagnetic environment is filled with the high density signal, and the space of electromagnetic environment is very complicated. Lots of problems such as how to solve the intra-system EMC and how to make the electronic equipments operate normally in the complicated environment are paid much more attention.
Some explorative researches on the intra-system EMC are studied as follows in this paper:
Firstly, from three factors of EMI, analyzing the mechanism of intra-system EMI in detail, including the features of interfering transmitter, sensitive equipment, antenna and radio wave when transmitting in different electromagnetic environment; establishing the corresponding mathematic model combining with the standard of EMC, analyzing the intra-system EMC by the method of class screening.
Secondly, based on the theoretic derivation and by the development platform of Microsoft Visual Studio.NET 2005, developing a software by C# which is named“The analysis software 1.0 of EMC intersystem”, and it can be easily extended, easily maintained and has a good human-computer interaction. This software includes seven modules as follows: question input module, data acquisition module, usual calculation module, transmission loss module, calculation module of interference field intensity, analysis module of interference intra-system and output module of analysis report.
After finishing the software design, the help document of software was written, and then the demonstration of it was made.
At last, combining with the related literatures, making test for this software and it proves that there is certain applicability and it can play a guiding role for designing the intra-system EMC.
