基于ARM9的电力负控终端系统的设计

摘要

介绍了采用高端嵌入式单片机ARM9和嵌入式Linux操作系统构成的电力负荷终端系统,以及该系统的整体设计方案。终端利用嵌入式Linux操作系统为应用软件提供强大、稳定的资源环境,根据Q/GDW 374.1-2009《电力用户用电信息采集系统技术规范：专变采集终端技术规范》的要求,将智能电网管理终端多个任务划分为应用软件下执行任务多个线程,使得系统完成多任务的能力更强、稳定性更高%This paper introduces the Electric Power Load Management Terminals system which adopt the operating systems of ARM9 and Linux and the design of the system.The Electric Power Load Management Terminals have strong and steady application software depending on the Linux system.By the technique criterion Q/GDW 374.1-2009,the tasks of the smart electric network management terminals are resolved into several threads of the executive tasks under application softwares,thus improving the capability and stability with which the system implements multi-tasks
