[ 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msp430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、暖表的管理和数据采集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msp430单片机的智能网络水表，智能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。

利用低成本 、 高性能的 M SP430单片机作为基表进行硬件设计 ,使用了广泛应用的基于 R S - 485电气接口的异步串行通讯技术作为通讯方式 ,利用 SQL Server技术和 Visual C + +编程语言设计了远程数据采集系统的上位机管理软件. 文中给出了系统模型 ,并对其关键部分的数据采集器 、 集中器和上位机管理系统做了系统的分析.

Design of water meter remote-reading system based on MSP430 microcon troller intelligent network water meter

Zhang wenbin

(School of Information, Baoji University.)

Abstract: Because of its extremely high performance-price ratio, the single-chip computer (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, MSP430 SCC is the most typical and representative one. More and more problems are arising on the management and record-reading of water meter, electricity meter, and natural gas mater systems as the community development is growing fast. Aiming to solve these problems, the thesis designed a remote central meter reading system and intelligent water system, development of intelligent resident community and the high demand of one meter per family project. This 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 meter network.

This system used of the MSP30 microcontroller which is low cost and high performance as the principal part to design hardware ,used a synchronous serial communication technology based on RS-485 electric in terrace as communication means SQL Server technology and V C++ program language are used to design the remote-reading management software system. This paper systematically introduces the model of the system and the critical part of the system such as data collector, concentrator and upper-level manage system.

Key words: automatic meter reading system; concentrator; MSP430 microcontroller; RS-485 bus; interlli-gent network water meter.
