摘　　要：介绍了一种基于低压电力线通信的路灯监控系统。为克服低压电力线信道的频率选择性和时变性,系统的信息传输采用了正交多载波方式。论文介绍了相应的硬、软件设计,并分析了该系统的经济性和实用性。This article introduces a road lamp monitoring system based on low- voltage power line channel. Orthogonal multi - carrier modulation is used to overcome frequency selectivity and time variation of low- voltage power line channel and its corresponding software and hardware designing architecture are introduced. At last its economy and practicability are discussed.

关 键 词：低压电力线 电力线通信 正交多载波调制
