摘要
介绍一种基于电话网络和语音识别技术的智能远程控制系统,利用电话机上的按键即可实现对受控设备的远程控制,广泛应用于生活和生产中。详细论述系统的主要功能、结构模型,重点分析振铃检测电路、摘机挂机电路、DTMF解码电路等关键模块的实现方法,并给出了程序流程。同时系统还引入语音识别功能,以RSC4128芯片为核心对用户信息进行检验,提高可靠性。实际应用结果表明,该系统电路简单实用,运行稳定,实时性好。
The keystroke on telephone is used to control the electrical equipment in intelligent remote control system based on telephone network and speech recognition technology which is used widely in life and manufacture. The main function,general structure and program flow are discussed. The realization method of ringing detector,answering, ringing off and DTMF decoder circuits are mainly anlysed. Otherwise,the system takes RSC4128 which has sound reminder and recognizing function as core controller to identify the passwords in order to increase the reliability. Practice shows that the circuit is simple and practical and the system works stable,real- time performance is good.
