摘要
首先介绍了低压电力线载波通信技术(PLC技术),其次介绍了热量表的结构和工作原理,探讨了低压电力线载波通信在热量表远程抄表系统中的应用,最后分析了低压电力线载波通信中的调制技术,即扩频技术和正交频分复用技术。
First, the low voltage power line carrier communication technology （ PLC technology ）is intro duced, then the structure and working principle of heat meter are introduced, and the application of the low voltage power line cartier communication in remote heat meter reading system is discussed. Finally, the modulation techniques in low voltage power line carrier communication are analyzed, namely the spread spectrum technology and orthogonal frequency division multiplexing technology.
