一种基于公话网的智能家居系统

Research and Design of A Smart Home System Based on PSTN

分析了智能家居的相关技术现状,提出了一种基于公共交换电话网的智能家居系统的总体方案,阐述了该系统的工作原理及软硬件的设计方法与过程.该系统利用计算机和红外遥控等技术实现了一个智能化的窗帘机构,采用双音多频信号进行信息的传输,实现了家居的安全防护和家电的远程控制.经过调试与检测证明,该系统具有性能可靠、功能丰富、易于使用等特点,具有广泛的实用价值.

In order to provide people with a comfortable, convenient, safe living environment, this paper analyzes the relevant technologies of the smart home system, puts forward a system project based on public switched telephone network, and expounds the principle and design process of the system hardware and software. An intelligent curtain machine is achieved by utilizing computer and infrared control technology; and security monitoring and remote control of household appliances is realized by adopting dual tone multi-frequency signal for information transmission. It can be demonstrated after debugging and testing that this system is reliable, full-featured, easy-to-use, and applicable to the vast majority of families and venue buildings with a wide range of practical value.
