摘　　要：分析探讨了一种基于AT91M40800的嵌入式综合数字继电器的软硬件平台的设计,详细说明了系统工作原理、硬件构成及软件流程。整个设计采用高速、高性能的ARM及CPLD硬件,外围电路十分简单,且由于引入了实时操作系统,该装置的监控能力在实时性、可靠性方面大大提高,可为电力系统里的中、低压系统提供良好的继电保护解决方案。A design of hardware and software platform based on AT91 M40800 embedded synthetic digital protection relay device are presented. The operational principle, hardware configuration and flow of software are described in detail. Due to CPLD with high speed and high performance, is adopted in line system, the peripheral circuits is very simple. And by iutroducing real time operation system（RTOS） , detecting and controlling capability of the system has improved greatly in real-time and reliability performance, and so it can provide a better solution forr middle or low vohage power system.
