Basic network management model is defined in third part of the paper . the model bases on analysis of electric power communication network function , integrates specification in tmn about network management function , uses model construction tool of uml , and partly realizes idl that used in developing network management platform 第三部分在分析电力通信网管功能的基础上，结合tmn体系中关于网络管理功能的规范，利用uml的建摸工具定义出了基本的网络管理模型，并且部分的生成了用于网络管理平台开发的idl 。
Based on lon field - bus ' s technology characteristic , criterion of protocol and intelligent communication , this paper gives a reading meter module designed project based on automatic meter reading ( amr ) system , which depend on lonworks technology , and designed project of lon bus networking administrating and software of related watching and administrating . this paper ' s designing object is automatic reading meter system ' s reading meter collection device , and raise whole designed project of reading meter system , on the other hand , achieve hardware circuit design of collecting device , software design of communication and system design of watching and administrating 本文在研究lon总线的技术特点、协议规范、智能通信的基础上，提出了基于lonworks技术的自动抄表系统的抄表模块的设计方案、 lon总线网络管理和相应监控管理软件的设计方案，以自动抄表系统的抄表模块为设计对象，提出了抄表系统的整体设计方案，主要实现其中抄表模块硬件电路设计和通信软件设计功能及监控系统设计，同时部分实现lon网络管理功能。
