摘要
探讨了基于ARM9和μC/OS-II的微机继电保护系统设计方案。系统以AT91RM9200芯片为核心构成高速保护装置,利用实时嵌入式操作系统μC/OS-II,不仅能较好地完成复杂的继电保护,而且可保证装置的处理速度。讨论了基于ARM9和μC/OS-II的系统硬件结构、开发特点以及系统软件流程。初步试运行效果表明,所设计系统运行的稳定性和健壮性是满意的。
The paper explores how to design microprocessor-based protection device based on ARM9 and μC/OS-Ⅱ. AT91RM9200 is adopted as kernel of high speed protection device and μC/OS-Ⅱ is adopted as software platform. The protection system can not only achieve complicated protection task, but also improve the reaction speed. The paper discusses the hardware frame, and developing features as well as software flow of microprocessor-based protection system. The preliminary running effect of the system shows that it is satisfactory in running stability and robustness for the microprocessor-based protection function.
