摘　　要：微机继电保护装置作为智能化的工业控制设备,取代传统的继电保护装置已成为一种必然趋势。本文着眼于现阶段城网和农网改造中对低压配电网络的继电保护,探讨了基于ARM7系列的LPC2214的微机继电保护装置的系统设计方案,讨论了该装置的硬件系统结构以及采用源码组装技术及源码资源库管理技术对μC/OS-Ⅱ嵌入式系统进行改进,给出了系统的软件流程。该系统功能完善、运行可靠、实时性强,可维护性和可移植性高,充分体现了ARM技术应用于微机继电保护系统的优势。It has become an inevitable trend that microprocessor-based protection device as intelligent industrial control equipment replace the traditional relay protection. The paper foucuses on the relay protection in the transformation of low voltage city and rural distribution network, exploring how to design microprocessor-based protection device based on ARM. The paper discusses ＇the hardware adopted LPC2214 belonged to the series of ARM7 and the μC/0SⅡ embedded systems improvements based on source code warehouse and assembling technology, as well as the system software processes. The microprocessor relay protection apparatus based on I.PC2214 and μC/0SⅡ Real-time Operation System has better real-time performance, reliability, maintainability and portability that reflects fully the advantages of the ARM technology used to relay protection.
