基于单片机的家用电器远程电话控制
摘要
目前,越来越多的住宅向着智能化,人性化的方向发展。其中家用电器的远程控制正被推广开来。本着低能耗、无污染、使用简单方便的原则。本文设计的是一种基于AT89S51单片机的远程电话控制系统。该系统是以AT89S51为核心、通过现在的个人通信手段,实现基于PLMN(陆基移动通信网)和PSTN(公用电话交换网)的电话远程控制系统。ITT及我国标准共同规定,电话远程控制系统(ITRCS),以PSTN与PLMN通信网作为传输介质,以部分标准程控交换信令(DTMF双音多频信号,振铃信号,回铃音信号等)作为系统控制命令,使用户实现在远端通过移动电话或者固定电话发送DTMF双音多频信号对近端电器设备进行远程控制。本次设计的电话远程控制系统不需要再进行专门的布线,不占用无线电频率资源,从而可避免电磁污染。用户只有输入正确的密码才能控制家电,从而提高了安全性。该系统设计实用,功能灵活多样,可靠性高,操作方便,可以广泛地应用于家庭或者其它场所的智能控制。

The Telephone Remote Control System for Household Electronic Appliance Base on The Microcontroller
Abstract
Currently, more and more residential develop to the intelligence and humanity. Among them, the remote control of home appliances is being promoted. Research follows the principles of Low energy consumption, pollution-free, easy to use. The article designed the remote telephone control system which based on microcontroller AT89S51. Basing on the PLMN and PSTN, the system which uses the core controller Single-chip puter AT89S51 realizes long-distance control household appliances. The telephone control system (ITRCS) which uses the convert and voice information receives DTMF code from the , and interpret the code, the core controller controls the state of household appliances responded to the interpretation. Long distance control of telephone does not require special wires distribution and does not take up wireless frequency resources. Electro ic pollution can thus be avoided. The designing of a system of long-distance control based on sound processing technology and DTMF decoding technology is presented in this paper. Only through inputting the correct password to control them, the users can control the condition of household electrical equipment, so the system security can be improved. This system is practical, and the function is flexible, and the operation is convenient with high
