Realization of Low- Voltage Power Line Carrier Communication System Based on PL3200

Abstract：This paper has introduced the basic idea of low- voltage power line carrier communication system.Simultaneously a Low- voltage power line carrier communication system has been made with the PL3200 of "Xiaocheng" company, which used QPSK modulating technology and CRC error- correcting codes.The experiment of power line carrier communication has been done by trying to transfer signal over the indoor 220V low- voltage power network.To sum up, the communication over the low- voltage power network is proved to be workable.
