摘要我国的人均水资源短缺，而且水的浪费问题严重，人们普遍缺乏节水意识。另一方面，传统的机械水表不仅需要人工抄费，还存在许多其他弊端，已经不适应社会的发展。为了解决这些问题，科学的利用水资源，智能水表技术获得了快速发展。本文以医院水表为对象，设计了以单片机MSP430f149为核心的IC卡水表控制系统。

本文首先根据水表所要实现的功能提出了系统的总体方案设计，然后详细介绍了各个功能模块的硬件电路。接着进行了系统的软件设计，依据模块的功能需求画出了主要程序的流程图。最后对本课题的研究成果以及其中的一些不足进行了总结和反思。42475

Title    The design for IC card water meter control system               

Abstract

Our country's per capita water resource is short , and the problem of wasting water is serious.People lack of awareness of water conservation. On the other hand,the traditional mechanical water meter not only need manual copying costs,but also have many other drawbacks. It is no longer meet the development of society. To solve these problems and use water scientifically, smart meter technology has developed rapidly. This paper take the hospital water meter as object, designing a IC card water meter control system with  MSP430f149  microcontroller as the core. Firstly, According to the The water meter functions to be achieved, The paper propose the design of overall program  system. And then  introduce the hardware circuit of each functional module in detail. Next, Design the software system. Draw a flow chart of the main program based on the functional requirements of the module. Finally, Summarize and rethink the research results of this project as well as some of the deficiencies
