摘　　要：介绍了一种基于低压电力线通信的智能家居系统及其相应的软硬件结构。为克服低压电力线信道的频率选择性和时变性,系统采用正交多载波方式传输信息。此外还提出了一种灵活的电力线组网方式,大大增强了系统的扩展性,最后分析了该系统的具体应用情况及效果。This paper introduces a Smart Home system based on low - voltage power line channel （ PLC ） and its collesponding software and hardware designing architecture. Orthogonal Multi - Carrier Modulation （OMCM） is adopted to overcome the frequency selectivity and time variation of low - voltage power line channel. Moreover this paper describes a flexible way to construct PLC networks, which boosts the expansibility of system. Finally, it discusses the application and practicability of the design.
