摘要:
 隨著科學技術的飛速發展，人們的視野不再局限于PC、服務器、交換機、路由器等；近來，在硬件設備功能日益增強、價格越來越便宜的情況下，人們開始意識到技術如何與家居生活更貼近的問題。近年來家電網絡吸引了人們的目光，特別是那些國內家電企業，在國內已經成熟的家電市場沒有太大的發展空間的情況下，找到了增強企業繼續發展的動力。它能將家用電腦、網絡應用、娛樂教育三大應用集中在一體，具有網絡功能、數字化、智能化、信息化、低成本、穩定性強等諸多特點。
 目前實現家電網絡及家居自動化有幾種方式，如歐洲家居系統，歐洲設備總線等，提供的是網絡協議，從而使家用電器組成網絡。但目前最成功的是美國的ECHELON公司提出采用現場總線控制網絡——Lonworks，它使家電組成局部網，再通過網關和互聯網相連。
 我所設計的課題目的就在于如何運用Lonworks網絡來實現信息家電網絡。在研究和了解了Lonworks網絡結構及其特性后,發現智能節點的如何實現才是整個Lonworks控制網絡的能否實現的關鍵.設計以Lonworks網絡的神經元芯片為核心，再輔以功能強大的單片機P89C662處理信息，從而組成這一智能節點。一般由傳感器發出的各類信號由單片機進行處理，通過Lonworks網絡傳至計算機，實現檢測。再由人為定義的開關量通過Lonworks網來控制家電設備的運行與停止。關鍵詞：
 Lonworks網絡、神經元芯片、Lontalk協議、單片機P89C662
 

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.
