摘要:
 随着科学技术的飞速发展，人们的视野不再局限于PC、服务器、交换机、路由器等；近来，在硬件设备功能日益增强、价格越来越便宜的情况下，人们开始意识到技术如何与家居生活更贴近的问题。近年来家电网络吸引了人们的目光，特别是那些国内家电企业，在国内已经成熟的家电市场没有太大的发展空间的情况下，找到了增强企业继续发展的动力。它能将家用电脑、网络应用、娱乐教育三大应用集中在一体，具有网络功能、数字化、智能化、信息化、低成本、稳定性强等诸多特点。
 目前实现家电网络及家居自动化有几种方式，如欧洲家居系统，欧洲设备总线等，提供的是网络协议，从而使家用电器组成网络。但目前最成功的是美国的ECHELON公司提出采用现场总线控制网络——Lonworks，它使家电组成局部网，再通过网关和互联网相连。
 我所设计的课题目的就在于如何运用Lonworks网络来实现信息家电网络。在研究和了解了Lonworks网络结构及其特性后,发现智能节点的如何实现才是整个Lonworks控制网络的能否实现的关键.设计以Lonworks网络的神经元芯片为核心，再辅以功能强大的单片机P89C662处理信息，从而组成这一智能节点。一般由传感器发出的各类信号由单片机进行处理，通过Lonworks网络传至计算机，实现检测。再由人为定义的开关量通过Lonworks网来控制家电设备的运行与停止。关键词：

Abstract:
 With the development of science and technology, people begin to pay less and less attention on the PC、server、switchboard and so on; Nowdays people come to realize the problem, that is how to use the new technology in the peoples’ daily life since the function of hardware are strengthened and its low price. In recent years, the household electrical appliances net catch the eyes of people, especially some enterprises. Since the market of household electrical appliances have no space to widen, the “net” becomes theirs new motive. It has many characteristics, such as the net function、digitalized、stabilized and so on.
 There are several ways which can realize the HEA net and automation of live, such as CAN、PROFIBUS and so on. But the Lonworks which put forwarded by ECHELON is the most successful. Different kind of HEAs gathered by it, being a LAN, then connected with internet by means of gateway.
 The motive of my design is how to use Lon technology to build a HEAs net. I realized that the connect unit is the base of how to build a HEAs controlnet after I knew the structure and characteristics of Lonworks. The connect unit system based on the nerve chip of Lonworks, assisted with MCU P89C662 to deal with all kinds of signals. Usually, the signals processed by MCU, then transmitted to PC to be monitored. At last, the HEAs will be controlled by a switch which has been defined by people.
