基于电话网络的远程家电控制系统

The controlling system of home appliances in long-distance based on the telephone net

本系统采用MCS-51单片机,信号传输方式基于电话网络的双音多频信号,并集成标准化的电气接口,将家电连接到该系统上,从而实现远程控制家电的目的。在结合实际项目的基础上,文章将分别从系统方案、电路原理和软件设计等方面,对该系统进行了全面的探讨和研究。

This system adopts MCS-51 single chip microcomputer and its signal transmission mode is the two-voice multi-frequency signal based on telephone network. It integrates the standardizational electric interface to link the household appliances to the system so as to achieve the aim of controlling them in long-distance. Combined with the practical project this paper fully studies this system from the following aspects system scheme circuit principles and software design.
