摘要
本文采用了流行的扩频技术、根据扩频芯片SC1128设计了电力线调制解调器,在硬件系统的基础上,我们设计了一套切实可行的软件方案。方案规定了通信协议,所有的软件设计都是围绕着这套协议展开的,这个协议包括帧头,帧长,数据块,校验和,帧尾五部分。
The article adopts the prevalent technique of Spread Spectrum ,and designs a kind of Power Line Modem based on the SS chip SCl128,we design a set of usable softwares scheme on the basis of the hardware system.The scheme regulates the communicat ion protocol,all the software designs are laid out based on the protocol,which includes frame head,frame length,data block,check sum and frame trail,
