文档介绍：摘要
单片机自20世纪70年代问世以来,以其极高的性能价格比,受到人们的重视和关注,应用很广、发展很快。而51单片机是各单片机中最为典型和最有代表性的一种。随着我国城镇建设的快速发展,有关城市的水、电、气、暖表的管理和抄表出现的问题也日益突出,根据自来水网的改造、智能小区的建设以及实施“一户一表”工程的需要,本文设计了一种基于AT89C5单片机的智能网络水表,智能网络IC卡水表通过集中器和上位机管理系统连接,将水表的数据传输给远方的上位机,同时上位机管理系统通过集中器对智能网络水表进行监测和管理。
本文采用AT89C51单片机作为主控芯片,开发一种基于IC卡技术的智能水表。该智能水表可实现总水量累计、月水量统计、水费计算与管理(报警金额、基础水量、计划水量),以及水阀控制等功能。同时具有预存水费、欠费提示、欠费停水等功能。

Abstract
Because of its extremely high performance-price ratio, the single-puter (SCC) has been paid great attention to ever since it came out in 1970s of 20th Century, and has gained an extensive applicable field and fast development. Among all kinds of SCCs, 51 SCC is the most typical and representative one. More and more probelems are arising on the management and record-reading of water meter,electricity meter,and natural gas mater systems as munity development is growing to slove these problems,the thesis designed a remote central meter reading system and intelligent water system, development of intelligent munity and the high demand of one meter per family intelligent water mater will collect the data and transfer it to the remote upper-level managing system via concentrator and upper-level management system,while the upper-level management system is responsible for monitoring and managing intelligent water work.
In this paper, AT89C51 SCM as a master chip, the development of IC card technology based on the intelligent meter. The intelligent meter can realize the accumulated water, water, statistics, computing and management of water (the amount of alarm, basic water, the water plan), and valve control functions. At the same time with stored water and delinquent tips, delinquent water, and other functions.
