摘要
提出了采用MSK作为调制解调技术的载波通信系统,设计了基于高速数字信号处理器、大规模可编程器件,数字频率合成、软件解调的全数字通信模块,来实现低压电力线上较为可靠的中低速数据传输。经实测与分析表明,本系统性能优越、抗干扰能力强、可靠性好,可用于配网自动化、自动抄表、工业控制等对通信可靠性要求较高的中、低速数据传输场合。
This paper brings forward the idea of using MSK as carrier communication system of modulation and demodulation technology and designs all digital communication module based on DSP,CPLD,digital frequency synthesis and software demodulation to implement the reliable middle & low speed data transmission on low voltage power line. The actual tests and analyses show that the system has excellent performance,strong anti-interference capability,and good reliability and can be used in such middle & low speed data transmission occasions with higher demand of communication reliability as distribution automation,automatic meter reading system,industry control.
