文档介绍：摘要
电能是现今社会最为广泛使用的一种能源,影响着的提高。随着我国经济的高速发展,电力行业也得到了迅猛发展。在行业高速发展的同时,也对配网调度和供用电管理自动化提出了新的要求。然而,在当前国内电能计量管理中,尤其对于数量巨大的一户一表客户的管理,自动化水平仍然较低。传统的人工抄表方式工作效率低、误差大,更不能对电网故障进行紧急响应。因此,提高供电质量和可靠性,实施高效准确的电能表数据抄收方式已是当务之急。随着通信信息技术的发展,以及前人致力于电网管理自动化所做出的不懈努力,为改变上述情况提供了强大的技术支持。所以我设计了一种利用GPRS技术进行无线通信的嵌入式系统来完成智能抄表系统。
本文首先介绍了远程抄表系统的相关发展背景,现有产品和技术的特点;在考虑性能和稳定性的前提下根据本设计的要求选择了Philips公司的LPC2138作为主控芯片、Siemens公司的MC55作为GPRS通信模块;接下来对基于GPRS通信方式的抄表系统的整体设计思路进行了讨论,分析了目前比较常见的几种远程抄表方式;然后在对现有不同方案比较之下,分析了本文所述系统的整体实施方案,并着重阐述了系统软件设计思路和实现;最后对本系统发展前景进行了展望。

ABSTRACT
Electricity is wildly used by society,and it influences all fields of the social economy and the life of power industry has been developing rapidly with the fast development of the current level of the automatic management in work is low,especially in numerous users traditional manpower reading mode,which can not response to emergence immediately,is inefficient and has many it is urgent to improve the quality and security of power supply,and to realize the high effect and exact reading new request is realization of automatic attempering and management in the order to resolve the problems,it is necessary to resort to the embedded system based on munication technology.
The frame of this thesis is arranged as follows:Firstly it introduces the definition of administration of electric power management and relative background of development,and the characteristics of current technology and products. In considering the performance and stability under the premise of the design requirements,we choose the pany's LPC2138 as the master chip and the pany's MC55 as munication introduces the whole design of the electric power management system based on GPRS and embedded analyzes the functions of the system,and introduces the software realization of every part such as puter,puter,and reading summariz
