| 摘 要： | 介绍了一种基于电话网(PSTN)的远程智能控制系统.采用电话机上的按键作为控制命令按键,以公用电话网作为传输线路,将控制信号发送给远程智能控制系统,控制系统将收到的控制信号通过无线的方式发送到控制终端,来控制与控制终端相连的用电器.系统以MT8880芯片作为DTMF信号的编解码核心,利用单片机的智能功能实现对受控设备的控制,同时,为了提高安全,系统通过软件设置了密码.当需要远程控制时,操作者首先要拨打相应的电话号码;电话接通后,根据语音提示输入密码,便进入可对远地设备进行控制的状态.同时还具有,当系统收到异常信号时,自动拨打预存的电话号码,告知用户有异常情况发生,以起到远程报警的作用.这种控制系统具有简单、廉价、实用的特点,并且较一般的控制系统更为安全可靠.

| Abstract: | A tele-intelligent control system based on PSTN is introduced. It sends the control signals to the tele-intelligent controlled system with the phone keys as command keys and PSTN as transmission line. The control system receives the control signals and sends to the control terminals by wireless so as to control the electric equipment connected to the control terminals. With MT8880 as the DTMF signal decoding core the system achieves the control function by using AT89S52. The password is setup to improve the safety. If a user needs the tele-control he firstly dials the according phone number and then inputs the password by the guide of speech command to have access to controlling over the remote equipment. When the system receives abnormal signals it rings up the pre-reserved phone number to inform the users so it has the tele-alarm function. The system has the characteristics of the simpleness, cheapness and applicability and it is more reliable than conventional control systems. |
