摘　　要：为了解决LonWorks设备现场智能控制及远程监控的需要,提出了通过嵌入式网关实现LON网和以太网协议的转换方案。本网关采用电力线收发器PL3150和带有以太网控制器的微处理器LPC1778分别实现LonWorks网络和以太网的接口功能。同时还利用LPC1778内置以太网控制器搭建Web服务器,实现了一个远程监控平台,达到了远程智能交互与监控的目的。本文给出了该智能网关硬件平台和软件平台的方案和实现方法。This design is on the background of power line communication.In order to monitor and control the status of LonWorks Interface nodes,it comes up with a solution that transforming Lon-Works net flow between Ethernet flow through an embedded gateway.This embedded-gateway uses PL3150 power line smart transceiver as the interface to LonWorks network,and LPC1778 MCU with Ethernet module as the interface to Ethernet network.LPC1778＇s embedded Ethernet controller is used to construct a Web server.The gateway also realized a remote monitor platform,so as to monitor and control the status of nodes on LonWorks remotely.In this paper,the solution and the implement methods of the system hardware and software will be given.
