摘要
介绍了极低频甚窄带电力线载波通讯技术的原理 ,并给出了基于该理论的自动抄表系统的实现方法 ,以及在实验室环境和实践电力网上的上线测试结果。
This paper describes the principle of automatic meter-reading system with power line carrier (PLC) communications based on extremely low frequency (ELF) and ultra narrow bandwidth (UNB).The design scheme of the AMR system is illustrated.The test result under the lab conditions and in the real-world power net are also presented.
