基于ARM的电能量远程终端平台的设计

嵌入式系统是指以应用为核心,以计算机技术为基础,软硬件可裁剪,适应应用系统对功能、可靠性、成本、体积和功耗严格要求的专用计算机系统。电能量远程终端(ERTU)是电能量计量计费自动化系统的重要组成部分,其主要功能是自动采集电表数据,对采集到的数据进行分类缓存,响应前置机的召唤,上传数据到数据库,同时处理前置机发下的控制指令。本文介绍了基于ARM设计电能量远程终端平台的意义;以ARM微处理器S3C2410为核心的嵌入式系统的开发思路,并将其应用到电能量远程终端平台的硬件和系统软件设计之中的具体流程;介绍了系统测试方法。

Design of an ARM-Based ERTU

Embedded system is a special computer system which is based on computer technology and applications,it is variable for hardware and software,and its reliability,cost cubage and power consumption are very strict.The Energy Remote Terminal Unit is an important component of the energy metering and billing automation system.Its main function is to automatically collect meter data to classify the data cache,to respond to the front-end calls,upload data to the database,and process the control instructions issued by the front-end.This paper describes the idea of embedded system development which is based on the ARM microprocessor S3C2410,and also introduced the way to apply them to the design of the hardware and system software for the electric energy remote terminal platform.
