摘　　要：针对机载千兆交换机系统配置与自测试(BIT)要求,设计了一种基于单片机的嵌入式交换机系统。针对软件的移植性、扩展性要求,采用基于UML的面向对象设计方法,建立了软件的静态模型,给出了软件运行流程图及设计。通过在单片机平台上实现,表明硬件功能正常,软件能实现交换机系统的配置与自测试。Forcusing on the requirement of airborne gigabit switch system configuration and Build-In-Test （BIT）, a kind of embedded gigabit switch system is designed based on micro control unit（MCU）. Focusing on requirement of software portability and scalability, object-oriented design based on unified modeling language（UML） is adopted, static model of software is established,and software flow char and design are given. Via design and implementation on the MCU platform, the hardware function is normal, and the software can well implement the configuration and BIT for switch system.
