基于AT89S52的智能远程电话机控制系统设计

Design of a Long-distance Telephone Intelligent Control System based on AT89S52

针对信息化社会对于设备越来越高的智能化要求,设计了一个智能电话控制系统,该系统以AT89S52单片机和MT8880双音多频解码电路为核心,借助公共电话网络,通过电话实现对远程设备的分布式智能化控制.文中给出了系统的组成、工作原理及其软硬件设计.

For equipments＇ higher and higher intelligence requirements,this paper designs an intelligent telephone-based remote distributed control system.With MCU AT89S52 and MT8880 Decoder which is specially used for decoding multiple dual channel audio frequency signals as the core,the smart control system based on telephone can remotely control the electric appliances through the PSTN（Public Switched Telephone Network）.The article details the composition of the system,working principle and its hardware and software design.
