摘要
 水表作为供水企业与用户进行结算的唯一计量器具，在供水系统中起着极其重要的地位，尤其是大口径水表的管理，更是举足轻重。如何加强大口径水表的管理，提高现代化管理水平，一直是困扰供水企业的难点。为了实现水表数据的自动抄报,运用系统化、模块化设计思想,应用先进的计算机技术、无线通信技术和现代电子技术,采用分层、分布、分散式结构,设计了远程水表自动抄表控制系统.论文综述了抄表技术、无线通信技术、短信业务的发展与现状,详细分析了抄表系统的工作原理.在此基础上,对系统的硬件结构、软件功能进行了设计与实现.系统硬件主要由用户子系统、无线网络子系统和管理子系统三部分组成.用户子系统主要由数据采集与显示单元,数据集中器,通信控制单元和GSM手法器组成,实现水表数据自动采集与显示、多用户数据集中、控制指令和水表数据发送等功能;无线网络子系统采用现有GSM无线网络,采用GSM网络的短消息业务,将水表数据和控制时令以短消息形式实现无限远程传输;管理子系统由GSM收发器和计算机组成,完成对系统协调管理与水表数据处理.软件系统包括实现无线模块与PC机串行通信的动态链接库和应用软件系统界面三部分.远程水表自动抄表控制系统根据管理中心发出的采集、控制指令,将水表数据以短信形式,通过无线网络传输到管理中心,并对用户的用水情况进行控制。

Abstract
 As a water meter enterprises and users of clearing the sole measuring equipment in the water supply system plays an extremely important position, especially large-caliber water management, which is of paramount importance. How to strengthen the large diameter water management, improve the modernization level of management, have been plagued by water supply enterprises difficult. In order to realize the meter automatically copied and sent data, the systematic use of modular design, the use of advanced computer technology, Wireless communications technology and modern electronic technology, stratified, distribution, decentralized structure, design of the remote control meter automatic meter reading system. Papers of the meter-reading technology, wireless communications technology, SMS business development with the status quo, a detailed analysis of the meter reading system works. Based on this system, the hardware structure, software for the design and realization. System hardware subsystem mainly by users, Wireless network management subsystem and the subsystem consists of three sections. Users subsystem mainly by the Data Acquisition and Display modules, data concentrator, communications and control modules for GSM practices, achieving automatic meter data acquisition and display. Multi-user data centralized, command and control of meter data delivery, and other functions; Wireless network subsystem use the existing GSM wireless network, using the GSM network Short Message Service, meter data and to control a short season in the form of news unlimited long-distance transmission; Management Subsystem by the GSM transceiver and computer components, completion of system management and coordination meter data processing. The system includes software modules and wireless PC serial communications Dynamic Links to the application software and system interfaces three parts. Remote meter automatic meter reading system control center under the management of the collection, control commands, will be metered data messages and a form of wireless transmission network management center, users as well as the use of water under control.
