摘　　要：低压电力线通信技术由于其成本低、可靠性高和组网快等优点,成为近年来的研究热点。正交频分复用(OFDM)技术因实现简单、频谱利用率高及较好的抗多径和脉冲干扰性能,成为电力线通信的主要技术之一。文章在分析了电力线和OFDM特性后,给出了用DSP芯片TMS320C6418和单片机PIC16F690实现的基于OFDM的电力线城市路灯控制模块的软硬件结构。The technology of low-voltage power line communication（LVPLC） has become a hot spot of research in recent years due to its merits of low cost,high reliability and quick construction.Orthogonal frequency division multiplexing（OFDM） is a major technique of LVPLC because it is easy to realize,and has high spectrum efficiency and good performance in resisting multipath and pulse jamming.Based on the analyses of the features of LVPLC and OFDM,and by using the digital signal processing（DSP） chip TMS320C6418 and the single-chip microcomputer PIC16F690,the hardware and software structures of city street lamp control module based on OFDM are presented in this paper.
