基于单片机的电话远程控制家用电器系统设计

摘 要：本设计是以单片机AT89C51为核心、基于电话网络开发的远程控制家用电器的智能系统。该系统利用电话网传输数字和语音信息，远程控制部分接收电话网发送来的DTMF信号，对其进行解码，解码后由中央处理器AT89C51根据解码信息控制家用电器。电话远程控制不需进行专门的布线,不占用无线电频率资源, 还可避免电磁污染；通过嵌入式的智能语音提示, 突出的语音提示功能和密码控制系统, 可使操作者根据各种提示音及时了解受控对象的有关信息；通过发出语音命令用电话远程控制多个家电, 用户可以查询家电状态, 提供密码功能, 只有输入正确的密码才能控制家电, 从而提高了安全性；本系统功能灵活多样，可靠性高，操作方便，实用性强，可以广泛地应用于家庭或者其它场所的智能控制。

Telephone-based single-chip remote control home appliances

Abstract:The design is based on AT89C51 single-chip microcomputer as the core, the development of the telephone network-based remote control of the intelligent system appliances. The system is the use of telephone network to transmit digital and voice information, part of the remote control to receive telephone network to send the DTMF signal, decode it, decoded by the CPU AT89C51 control home appliances in accordance with decoding information. Telephone remote control without special wiring, radio frequency resources are not occupied, but also to avoid electromagnetic pollution; through embedded intelligent voice prompts, voice prompts to highlight features and password control system, will enable the operator based on a variety of tone keep abreast of information about the controlled object; issue voice commands through the phone number of the remote control home appliances, the user can query the status of appliances, provide the password function, only to enter the correct password to control home appliances, resulting in improved safety; the flexible design features diverse, high reliability and easy operation, practicality, and can be widely used in home or other place of intelligent control.
