摘要
电力线是一种分布广泛的载波网络,如何利用它实现信息传输,尤其是利用它解决“最后一公里”问题是现阶段网络构建方面研究的热点.文章第一部分首先介绍了PLC技术的发展历程及低压电力线通信信道的特点,然后分析比较了几种典型的PLC信号调制技术;文章在第二部分给出了PLC技术解决“最后一公里”问题的具体方案;最后,作者对PLC技术的应用前景做出了分析和展望.
The power-line is a widely distributed carrier, how to use it to transmit information, particularly to solve the “last kilometer” problem is the hot spot of network building. In the first part, this article introduced the phylogeny and the channel characteristics of PLC, then analyzed and compared kinds of representative signal modulating of PLC; in the second part, the paper proposed a concrete plan with PLC to solve the “last kilometer” problem; at last, the author has analyzed and forecasted the applying foreground of PLC.
