摘要
双音多频(DTMF)编解码通信具有抗干扰强、低成本、远距离的特点。本文提出基于DTMF远程通信的逆变电源系统。介绍DTMF收发控制器MT8880和三相PWM发生器SA8282的结构特性,由MT8880与单片机80C51和SA8282及IPM组成的基于DTMF技术的逆变电源,具有低成本高可靠远程数据通信的功能,形成远程遥测遥控逆变电源,扩大了逆变电源的应用范围。
DTMF coding and decoding communications feature strong anti-interference,low cost,and long distance.The inverter power supply based on DTMF remote communications is proposed in this paper.The structure characteristics of communication controller IC MT8880 and SPWM generator IC SA8282,the inverter power supply based on MT8880-DTMF and composed of MT8880 and AT 80C51 MCU as well as SA8282 and IPM are introduced,The inverter has the function of achieving remote communications with low cost and high reliability,so that expands the application scope of the inverter power supply.
