Sc1128 Power Line Carrier Communication Devices

In this thesis the data communication via the low voltage network was discussed. The SC1128 is a special homemade power Modem chip. After discussing the transmission channel property and noise of the low voltage power lines, the thesis explained the theory of the spread spectrum technology on the data transmission, thus to prepare for design the module of the carrier current communication based on SC1128.After theory analysis in depth, the design details of the schemes was discussed. A simple point-to-point power line communication system was implemented in software and hardware. The process was introduced from designing , making to debugging. At last this thesis gave the possibility of module based on SC1128 using in the street lamp system of guarding against theft.
