    摘要:

    为解决目前广泛使用的智能卡水表抗攻击、抗干扰性差的难题,设计了一种基于MSP430单片机的智能远传水表。系统由用户水表和用水管理中心服务器两部分组成,以MSP430F169单片机作为主芯片,外围扩展串口通信、液晶显示和网络通信3大模块。对水流量信号采集及处理后,通过LCD显示用水量等信息;串口通信与GSM短信模块进行通信,当余额不足时,水表发送报警短信并关断水阀;通过Internet建立用户水表和用水管理中心间的信息交互,管理中心可通过网络对用户水表进行集中管理,进行充值、查询余额等操作,用户使用更加便捷,是今后水表的发展方向,具有较高的应用推广价值。

    Abstract:

    An intelligent remote water meter based on MSP430 is designed to solve the problem of anti attack interference of smart card water meter which is widely used at present. The system consists of user water meter and water management center server. MSP430F169 microcontroller is used as the main chip. The main chip peripheral expands the serial communication, liquid crystal display and network communication. After collecting and processing the water flow signal, the information of water consumption is displayed by LCD, the serial port communication and GSM short message module are communicated, when the balance is insufficient, the water meter sends alarm short message and shuts off the water valve. The information exchange between user water meter and water management center is established through Internet. The management center can centrally manage user water meter through network, recharge value, inquire balance and so on, which provides convenience for user, and is the development direction of water meter in the future. It has high application value.
