摘要
提出一种基于双CPU架构的微机保护装置的设计方法与实现过程。以LPC2468和TMS320F2812为硬件核心,以前后台系统和嵌入式操作系统为软件平台进行微机保护装置的设计,具体介绍了系统的硬件功能以及软件流程图。具体阐述了一种基于CPLD的双CPU通信的软硬件实现过程,解决了传统单CPU处理速度慢、功能单一的缺点,使保护装置运行更加可靠、灵敏。
The paper describes design method and implementation process of microcomputer relay protection based on ARM microprocessor and DSP microprocessor. The system of microcomputer relay protection used DSP TMS320F2812 and ARM LPC2468 as the hardware core, utilizes foreground/ background system and embedded operating system μC/OS-Ⅱ as software core. then describe the function of hardware and the flowcharts of software. And the paper introduces specially the communication between double cpus based on CPLD. Compare with the traditional device which used single CPU,the new system run reliably and rapidly.
