摘　　要：针对目前电力线通信PLC存在通信距离有限的问题,提出了一种基于蓝牙技术以实现远程通信的方案。该方案以通用电力线载波通信芯片LM1893和蓝牙模块WRAP THOR 2022-1为核心,以AT89C51为主控单元设计了一个远程电力线载波通信系统,以解决音频信号的跨变压器传输问题。硬件系统由8个模块组成,并对系统整体的软件进行了设计,经过软硬件的双重调试,为实现远程电力线通信提供了一种可行的方案。As the current power line communication is limited in the short distance communication, a system based on Bluetooth technology is proposed and designed for remote power line communication, which, takes the universal power line carrier communication chips LM1893 and Bluetooth modules WRAP THOR 2022-1 as the core,and uses the AT89C51 as the main control unit. The hardware of this system is consist of eight modules. The software of the whole system has also been designed. Through de- bugging, the system is proved to be a feasible scheme for realizing the remote power line communication.
