摘　　要：MIC总线是一种在恶劣环境下具有高度可靠性的现场数据总线,在军事领域有着广阔的应用前景。文章着眼于MIC总线在国内的应用推广,简要的介绍了MIC总线的结构和特点,阐述了MIC总线常见的几种工作模式。结合MIC总线在实际工程项目中应用,重点分析了DOM方式下MIC工作原理,深入地剖析MIC总线在DOM方式下的通讯时序。在此基础上,提出了一种切实可行的应用方案,并完成了硬件和软件的设计。通过软件的方法,解决了MIC和单片机之间通讯的冲突仲裁问题。MIC is a bus, which possesses high reliable communications under severe environment and widely used in military field. With the eye of extending the internal application of MIC, the components and characters of MIC bus are introduced .Several operation modes of MIC are presented briefly in this paper, Combined with the application of MIC in the project, the communicating timing based on DOM mode is analyzed in detail. According to above analysis, a doable design is presented. The hardware and software design are finished, Using the software method, the conflict of communicating between MIC and singlechip is solved.
