一种基于扩展频谱通信技术的集中抄表系统

A power consumption system based on spread spectrum communication technology

根据电力系统现代化的需要,采用电力线作为底层网络的通信媒介,设计出基于扩展频谱通信技术的抄表系统。通过分析扩频通信技术原理,提出利用直接序列扩频通信技术的方法,以克服电力线作为传输媒介的缺陷,最后给出了运用于电力线通信的调制解调器的总体设计。实验证明,该系统具有多种通信方式和灵活的地区适应性。

Considering the requirements of power system's modernization, a power consumption automation system is designed on a system level,and the spread spectrum communication technology is adopted as the main way of communication. Power line is used as the communication medium of the bottom network, and the advantages and disadvantages of power line communication are discussed. At last, a power line modem based on the spread spectrum technology is designed to overcome the disadvantages of power line communication.
