摘 要

介绍了以单片机AT89C51、双音多频解码集成电路MT8870、语音录放集成电路ISD4003和个人计算机为核心，通过现有的电信网络终端或互联网网络终端来进行远程遥控的多网络智能远程控制系统的设计思路，并给出了其系统原理和软件设计方法。多网络智能远程控制系统遥控技术是通过一定的手段对被控物体实施一定距离控制的一种技术，常用的方式有无线电遥控、有线遥控等。同时，由于电信线路各地联网，互联网遍布世界各地，因此，可以充分利用现有的网络资源跨省市，甚至跨越国家无限长度地进行智能遥控。该方法采用单片机进行智能控制，并利用不同的语音提示及计算机软件来达到对于不同操作的提示及对受控方状态信息的反馈，从而实现友好的人机交互界面，使操作者能够实时了解受控方信息，并最终使产品达到交互式与智能化的水平。

Intelligent Remote Control System Design

Abstract

Introduced single-chip microcomputer AT89C51, DTMF decoder IC MT8870, IC ISD4003 voice recorders and personal computers as the core, through the existing telecommunications network or the Internet network terminals for remote control terminal of the multi-network remote control system for intelligent design ideas, and given the principle of its system and software design methods. Multi-network remote control system of intelligent remote control technology is adopted by means of a charged object a certain distance from the control of the implementation of a technique commonly used way radio remote control, wired remote control and so on. At the same time, around the network as a result of telecommunications lines, the Internet all over the world, therefore, can take full advantage of existing network resources, inter-provincial city, or even across the country for an unlimited length of intelligent remote control. The method is carried out using single-chip microcomputer intelligent control, and the use of different voice prompts and computer software to achieve operation of the different tips and information on the controlled side of the state feedback, in order to achieve a friendly interactive interface to the operator in real time understanding of the controlled side information, and ultimately to make our products reach the level of interactive and intelligent.
