摘要
简短回顾了国内外低压电力线通信发展的历史及现状,介绍了低压电力线传输与调制技术,重点针对电力线通信网络问题,提出了低压电力线通信的3种组网技术模式新概念:即家庭组网、专用组网和接入组网,并分别就各网的前途、组网设计、拓扑结构和技术支持进行了讨论;对电力线通信网的未来发展和面临的主要问题,提出了一些建议。
The paper reviews the historical development and status of the domestic and foreign low-voltage power line communications, introduces briefly low-voltage power line transmission and modulation technology. Focusing on PLC network, three new models of low-voltage line network, such as home network, private network and access network, are put forward, and the outlook, design, topology and technical support of each network are discussed. Some suggestions are given about major problems of the PLC network future development.
