摘要
分析了基于直接序列扩展频谱技术的载波通信原理。提出了一种电力载波芯片SC1128的电力载波通信线路方案。给出了硬件电路设计框图。利用220V低压电力线传输高速数据,具有不用布线、覆盖范围广、连接方便的显著特点。该方案可在智能小区等的监测控制中得到较好的应用。
Analysis was made to carrier communication principle based on direct series spread spectrum technology. Power carrier communication line plan of a kind of power carrier chip SC 1128 was put forth. Hardware circuit design frame diagram was given. Using 220 V low-voltage power line to transfer hign speed data has obvious advantages of without wiring, wide covering, and convenient connections etc. This plan can be better applied in monitoring & control for intelligent areola.
