摘　　要：本文旨在开发一种基于单片机的新型智能网络电表数据集中器,实现HFC智能网络电表系统项目的技术要求。本文提出了硬件设计方案并给出了单片机和网络处理器的选型。在软件系统中采用KeilC51的集成开发工具设计了数据集中器软件。该软件主要由三大功能模块构成,分别为数据集中器模块,串行数据通讯模块,网络通讯模块。根据项目的总体要求,遵循上位机与电表数据集中器的协议规范,以及数据集中器和下位机电表的协议规范进行设计。通过调试表明了该数据集中器可靠的运行。New microprocessor-based data collector software of intelligent network electric meters was developed in this dissertation to meet the technical requirements of Hybrid Fiber Coax （HFC） intelligent network electric energy meter system project. This paper puts forward the hardware design schema and chooses the MCU and network process. In software system, it uses Keil C51 as the integrated developing tools. This software is composed of the following three functional modules： data collector module, serial data communicating module and network communicating module respectively. Based on the project requirement, it follows by the protocol rules between upper machine and electric meter data collector, between lower machine and electric meter data collector. After the testing, the electric meter can work out efficiently.
