摘要
基于ML7020设计了一款用于变电站数据采集终端的专线MODEM模块,通过此专线MODEM模块实现了变电站数据采集终端与主站之间的数据可靠传输,简化了传统专线MODEM模块用分立器件设计的FSK调制解调电路。通过实验室测试和现场应用验证,表明基于ML7020设计的专线MODEM模块通信可靠性高、抗干扰能力强。
This article designs a dedicated MODEM module for substation data acquisition terminals based on ML7020.Through this dedicated MODEM module,reliable data transmission between the substation data acquisition terminal and the main station is achieved,simplifying the FSK modulation and demodulation circuit designed with discrete components in traditional dedicated MODEM modules.Laboratory tests and field applications have verified that the dedicated MODEM module designed based on ML7020 has high communication reliability and strong anti-interference ability.
