摘      要

 现代家庭中水、电、气表俗称“三表”。传统的入户抄表方式误差大、统计工作量大，不仅给用户带来了不便，而且占用大量的人力资源，同时还存在收费难的问题。自动抄表系统(AMRS)能够即时抄取和传输，并进行自动核算管理数据，同时对客户的使用状况进行监测分析，给水、电、气管理的自动化带来了极大的便利。而基于GPRS（General Packet Radio Service）无线网络的远程抄表系统，运用先进的GPRS无线通信技术对用户现场进行在线检测和实时监控，从而达到数据抄读准确，数据传输及时的目的，也提高整个系统的工作效率，达到资源的优化配置。很多地区集抄系统试点情况良好，但一推广抄表成功率就下降了，可见，维护管理同样也很重要。

Abstract

IN modern families,water meter and electric meter and gas meter is frequently-used.The traditional way to join in a table is big and heavy workload statistics,not only bring inconvenience to users,and takes a lot of human resources, there is the difficult question.The list system sees can copy and transfer from the accounting and management of data and to customer of use in monitoring and analysis,shrunk,and management of automation with great facility.GPRS（general packet based on the radio deliver）wireless network remote systems,use a form of advanced GPRS wireless communications technology to the user on the scene conducted on-line real-time monitoring and data by copying to read accurate, timely for the purpose of data transmission,and improve the system of efficiency, optimize distribution of resources. many areas set by the system is good, but a promotion by the success rate has declined,therefore,the administration also very important.
