摘　　要：MIC总线是专门为了解决现代军事及工业领域中极其复杂和恶劣的工作环境下电力/数据的分配和管理而开发的一种具有结构简单及高可靠性的现场总线;在详细分析MIC总线的体系结构和通信协议之后,提出了基于PXI总线体系结构的MIC总线通讯模块的软硬件设计方案;系统可通过PXI总线灵活配置MIC的各种通讯模式参数,具有即插即用、高可靠性和小型化易集成等特点;实验证明,主模块PIM工作模式与远程从模块间数据通讯稳定且可靠,对国内MIC总线的研究与应用有重要意义。MIC bus, which is developed specially for solving power/data distribution and management under severe environment, is a kind of field control bus that provides high reliability. A based PXI MIC bus communication model is designed, which is provided with plug and play capability, It need smaller space and higher reliability, The paper discusses the hardware and software design scheme of MIC bus communication model via analyzing the MIC bus architecture and protocol. The design actualizes communication betwen PIM and remote modules reliability in military and industry field.
