摘要
低压电力线载波通信以其覆盖范围广、连接方便、应用潜力巨大的显著特点,而被日益关注,成为近年来研究的热点。在介绍低压电力线载波通信特征的基础上,分析了正交频分复用和扩频技术在低压电力线载波通信中的应用,探讨了低压电力线载波通信在远程抄表和接入Internet的应用。
With the distinctive feature of wide-range coverage,convenient connections and great potential of applications,low voltage power line communication(PLC) had become a major concern and hot topic for research.Based on the introduction of characteristics of communication channel of low voltage power line communication,two kinds of new technology——orthogonal frequency division multiplexing(OFDM) and spread spectrum communication(SSC) applied widely in PLC were analyzed.Then the application of low voltage PLC in remote meter reading and accessing Internet was discussed.
