基于ARM9和Linux系统的状态监测代理系统开发

摘要

介绍了ARM嵌入式微处理器的特点和应用,并对嵌入式片上系统(SOC)技术进行了简单分析；重点阐述了基于ARM9核的SOC片上系统AtmelSAM9260的输电线路状态监测代理系统的硬件平台和软件系统设计.实现了在一个局部范围内管理和协同各类输电线路状态监测装置,并代替各类装置与主站系统进行安全的双向有线和无线GPRS数据通信,同时满足不同厂家、不同类型的甚至不同线路的一组监测装置的标准化、智能化、安全化接入.为科学规范的建设坚强智能电网输电线路状态监测系统打下基础.%The paper introduces the characteristics of the embedded ARM microprocessor and its application,and gives simple analysis of embedded chip system (SOC) technology.It mainly describes the hardware platform of transmission line state monitoring agent system based on ARM9 core SOC chip system AtmelSAM9260 t and the design of software system.The state monitoring device is managed in a local scope and is coordinated with all kinds of transmission lines,and it replaces all kinds of safety two-way cable and wireless GPRS data communication between various devices and master station system,At the same time,it is able to make standard,intelligent and secure access of a group of monitoring devices with different manufacturers,with different types or with even different line.This will lay the foundation for the construction of state monitoring system of intelligent power grid transmission line.
