2、用单片机AT89C51为红外遥控发射接收芯片， HS0038作为红外一体化接收 管，在此基础上设计了一个简易的红外遥控系统。该系统包括发射和接收部分，当红 外接收器接受到红外遥控信号后，将光信号转变成电信号，经放大，调解，滤波后， 将信号送入单片机中进行信号识别解码，然后进行数码显示。另外本系统有16个按键， 可用于扩展控制其他电路。本设计在proteus上完成仿真。本设计方案以软件为主，基 于市场的需求，结合红外遥控设计简单、作方便、成本低廉等特点。 关键词：编码；解码；单片机；红外遥控编码；解码；单片机；红外遥控 II ABSTRACT With the kind of household
3、 appliances increased and the use of remote controller being more and more universal. Many people start to choose IR (Infra-red) remote-operated controller. But the market of IR (Infrared) learning remote controller is not as well as the technology in our country. In paper a design of IR learning re
4、mote-operated controller with touch screen is to be discussed to improve the production of IR learning technology. The traditional method for IR coding is collecting the IR signal through Interrupt mode or Query mode by single-chip microcomputer. In some condition this method needs repeat for many t
5、imes. In paper, PC (Personal Computer) is used to record the whole wave and optimize the wave through software, which makes it easy to finish the decoding for one time; By experiment, the infrared emission distance is turned to be affected by the duty ratio of carrier wave and the current of IR emit

With the data of experiment and the function“lsqcurvefit“ of matlab, the wandering of touch screen is settled by the corrected parameters. In color display, every key is simplified by combination of Arrow keys、Enter key and virtual digital tubes, which successfully solve the problem of wasting the resources of single-c
