Lonworks Technology-based Network Appliance Controller Study

Enter the twenty-first centuries,the development of technolgy is based on the human being.The development of electronics and information is immersed deeply in our living,it provides comfortable,convenient ,safety living environment.Network appliances is newly arisen appliance,besides having traditional functions,it also has network communication ability.It can accept exterior information,and adjusts its relative function immediately, forther more,it can deliver message about itself to the outside supervise.Networking and intelligent is the characteristics of network appliances.At first, this paper introduces the function and sigificance of develop network appliance. Second,it introduces more details about Lonworks technique which used in the intelligent home network.The appliance controller used 89C51 MCU as it's core ,Neuron 3150 chip as communication module,and power line modem chip SC1128 as transceiver. The main research in thesis is communication method of network appliance under home network and solved a few keys link in the network appliance data passage.This paper also gave two kinds of serial communication between 89C51RB2 MCU and Neuron chip ,power line transceiver was designed too.
