随着人们生活水平的逐渐提高，人们对生活质量的要求越来越高，出现了智能家居系统，本课题设计的是智能家居系统中的子系统——基于以太网的嵌入式智能抄表系统。 基于以太网的嵌入式智能抄表是一个以总线技术、嵌入式技术和以太网三种技术相结合的系统。整个系统分为两大模块：数据集中器模块以及上位机管理软件模块。其中数据集中器模块采用微芯公司的PIC16F877A微控制器通过RS485总线对四表（电表、水表、气表、热表）数据进行采集，设计出来数据集中器的底层通信硬件和软件。上层通信模块利用PIC16F877A微控制器与W3100协议栈芯片、RTL8201芯片来实现。其中上层通信软件的设计是利用WinSocket接口实现TCP数据的发送和接收、UDP数据的发送和接收、IP协议层的实现、对各个数据集合器IP地址网关等的设置以及统计各个数据集中器所采集的电能和远程控制等功能。 最后对智能抄表系统进行了测试。实验结果表明，该系统操作灵活、性能稳定，很适合在普通居民住宅小区进行推广。整个课题取得了预期的效果。

Gradually with the increase of people’s living standard,it is appeared to smart home system.while This paper will design Auto Meter Reading of smart home system. The AMR based Ethernet Network is an automatic system integrated by embedded system, Ethernet, assemble line.The whole system is divided two module,the one is data collection block,the other one is the software and management of upper computer block.In data collection block, adopting the things what is made up of PIC16F877A microcontroller of Microchip Company and RS485 assemble line realizes collection for data of four meters (electronic energy, volume of water energy and gas),and design bottom communications of data collection.And then upper communications block adopt PIC16F877A microcontroller, the role of TCP/IP protocol W3100 chip,RTL8201 physical layer chip .The software uses embedded C language programmer, the procedure is mainly achieve Ethernet communication in use of WinSocket connection and collect data which passage way is used of collective chips from Microchip Company. It realizes sending and receiving of TCP data and UDP data by WinSocket ,and config the IP address, realizes the IP protocol,design the soft of slient port that’s port of computer by using Delphin languge at last . At last,the whole system is tested. Result of the experimentation indicate the system provided with flexible operation, jarless performance so that it is extended in dwelling house of plain residenter.the system obtain anticipative purpose.
