摘要
介绍了在配电线上实现数据传输的PL2 0 0 0低压扩频芯片 ,包括其结构特点、工作原理以及用它构成的自动抄表系统。由于采用了扩频载波技术 ,抗干扰能力强 ,输出信号谐波成分少 ,可满足电力线通信的要求。
In this paper the characteristic and the function of PL2000 chip are introduced,and as the application of the chip,an auto reading meter system is presented.The system has many advantages,for instance higher anti interference,less resonance wave.So it is a good method of power line communication.
