摘    要

基于市場的需求，結(jié)合紅外遙控的設(shè)計簡單、方便、成本低廉等特點(diǎn)，采用了51單片機(jī)作為遙控發(fā)射、接收的主芯片，HS0038作為一體化紅外接收管，對載波信號進(jìn)行接收、解調(diào)、放大、檢波、整形等。在此基礎(chǔ)上設(shè)計一個簡易的紅外遙控控制電機(jī)轉(zhuǎn)速的系統(tǒng)。系統(tǒng)包括紅外發(fā)射和紅外接收兩大部分，本設(shè)計實(shí)現(xiàn)了電機(jī)的基本功能：多級調(diào)速功能。另外本設(shè)計可以增加按鍵的個數(shù)，可用于擴(kuò)展控制其他的功能。

ThE DESIGN OF ThE INFARED REMOTE CONTORL BASED On 51-MCU

 
ABSTRACT

The design was based on household products, Considering that infrared remote control is simple, easy to operate, low-cost, I use a special launching and receiving chip which depends on remote control, the signal demodulation, amplification, filtering, shaping, etc. On the basis of this chip a system of intelligent infrared remote-control was designed for the fan. The system consists of the part and the receiving part. This system is designed to achieve basic function of fans: two kinds of speed. and the function of two kinds of wind which are the natural wind and the normal wind.
