基于PSTN与DTMF的家用电器远程控制系统

随着电话和家用电器的普及,利用个人通信终端实现对电器设备的远程控制是许多电器设备制造商关心的技术。本文利用DTMF（Dual Tone Multi Frequency,双音多频）技术在现有的PSTN（公用电话网络）设计控制多路家用电器的智能远程遥控系统。

The Study of Remote Control System of Household Appliances Based on PSTN and DTMF

As the widespread use of phones and household appliances,more and more manufacturers of the electrical equipment highly pay attention to the technology which by using personal communication terminal to achieve the remote control of electrical appliances.This thesis is based on the technology of DTMF(Dual Tone Multi Frequency) in the current PSTN(Public Switched Telephone Network) to design an intelligent long-distance remote multi-control system for the appliances.
