摘要
电力网由于覆盖广泛,无需重新布线,永久连接,不存在射频电磁污染等优点,成为构建智能家居系统的首先物理媒介。本文介绍了一种基于扩频技术的电力线调制解调芯片SC1128,分析其通信特性,与国内外同类产品进行了对比。并以SC1128芯片为核心,设计了电力线收发器。最后将其应用于智能家居系统,基于Lonworks技术搭建了智能家居网络,为未来的智能家居系统研究提供参考平台。
Because of its advantages of extensive coverage, no new line, forever connection and no RF electromagnetic pollution, PLC is the first choice for constructing Home Network. This paper introduces a power line modem chip SC1128 based on Expanding Frequency technique, analyzes it＇s characteristic and compare it with other modem chips. Using SC1128, designs a power Line Transceiver. In the end, apply this transceiver in Smart Home System, construct a Intelligent Home Network based on Lonworks techniques, hope to provide a hardware foundation for future research in SHS.
