基于单片机的语音遥控硬件系统设计

摘要

红外线遥控就是利用红外线传递控制信号,实现对控制对象的远距离控制。系统以AT89S52单片机为核心控制器实现红外线遥控语音录放功能,主要由红外发射部分、红外接收及单片机控制部分、液晶显示部分和语音录放部分组成,并且提供红外线遥控和近距离机械按键两种系统操作方式,同时带有实时显示系统工作状态的液晶显示功能,能实现对音频信号进行高保真度的录放过程。%Infrared remote control is the use of infrared transmission control signal,the remote control of the control object.As AT89S52 for the core of the system to design infrared remote controller for voice recording function.It mainly contains the IR transmitter,IR receiver and single-chip control part,liquid crystal display part and the voice recording components and provides close mechanical key and infrared remote control for two systems operate way,while working with a real-time display system status LCD display,can achieve high-fidelity audio signal recording process.
