摘要
本文介绍一种DTMF（双音多频）通信方式的远程测控系统。本系统采用总线星型复合结构，特别适应于缺乏电源供应的现场设施的多点测控。
This paper presents a detection and control system in which the DTMF method is used to realize data communication. The system is constructed in the form of bus and star. It can realize remotedetection and control, especially for the remote field where power supply is difficult.
