Characterization of indoor power line channel at 100kHz-60MHz

电力线是一种实现物联媒介的传输手段,近距离传输速率高,不用重新布线,它是一种即成的信息传输媒介。本实验设计了电力线信道实时测量方案,分析了电力线传输模型,实际测量了电力线在各种环境下100kHz^60 MHz频段的传输特性,并分析长度线径对电力线传输信道的影响,推出修正后的电力线在100kHz^60 MHz的信道模型,提出了电力线传输过程中线径与长度选择的方案,为建立电力线通信信道的可靠模型提供了理论支持。

Power line is a kind of transmission transmission in short distance. The indoor medium for the Internet of Things and has high-speed power line can be used without rewiring and thus transmission medium could be used directly. The program was designed to measure the real time power line channel. The circuit model of power line was analyzed, while the channel model and its transmission characteristic of the power line at 100 kHz to 60 MHz was measured under different environment. The impact of length and wire diameter on the power line was also analyzed, and the revised channel mode was set up and provided theoretical support for making the reliable channel mode.
