摘 要:为了能够将用户所消耗的电量方便快捷地上报给有关部门,本文设计一个远程抄表系统。该系统主要由电表、AT89C52单片机、数模转换电路、远程通讯电路和上位机组成。本系统利用AT89C52处理用户电表传来的脉冲信号,使之转化为数字信号,再利用RS232与RS485将数字信号传输到上位机进行显示。仿真结果表明,该系统能够准确测出用户消耗的电量,且该数据可以定期发送给上位机。38927 毕业论文关键词:远程抄表;AT89C52;RS232;RS485
Design of PowerRemote Meter Reading System for Village
Abstract: In order to make users’ consume on electricity reported to the authorities easily and quickly, a remote meter reading system was designed in the paper.The system consists of the meter, AT89C52 microcontroller, digital to analog conversion circuit, telecommunication circuit and the host machine. The pulse signal from user meter was processed through AT89C52, converted into digital signal and transmitted to PC for display through RS232 and RS485 in the system. Simulation results show that the system can accurately measure the amount of power consumed by the user, and the data can be sent periodically to the host computer.

引言
电能是最重要的能源,在现在这个社会中电能在现代社会中电能己广泛应用到社会生产的各个领域和社会生活的各个方面。在用电的时代里就需要电力部门准确快捷的计算出用户所用的电量,它的准确与否直接关系到国家与用户的经济利益,所以研究小区用电远程抄表系统是很有必要的。
原来的电力部门都是上门抄电表,这给电力部门以及用户带来了诸多的不便以及社会治安问题。随着社会的发展,时代的进步,人类已经开发出越来越多的远程抄表系统,这些系统各有特色,功能多种多样,能够应用在各种不同的场合。这促进了小区智能化的实现。
本设计所研究是的小区用电远程抄表系统。它是以单片机AT89C52为核心,它能够对数据进行判断,存储,处理以及远程传送等功能以达到远程抄录的目的,这是适应时代发展的需求。
