摘要
 紅外遙控被廣泛用在家用電器和儀器儀表中，由于紅外裝置具有體積小、功耗低、功能強、成本低等一系列優點，因而在彩電、音響設備、空調以及玩具等其它電器裝置上也紛紛采用紅外系統。在工業領域，使用紅外設備來傳輸很廣泛，采用紅外遙控不僅安全可靠而且沒有電氣干擾。
 介紹了Silan 6122紅外遙控器芯片的原理，在了解了其發射的編碼脈沖信號波形后，設計了基于單片機AT89C52的紅外遙控器解碼器實現了一種利用MCS一51單片機的外部中斷實現紅外遙控的接收裝置，著重闡述了紅外遙控解碼程序的實現方法, 并對碼型進行了分析, 確定了解碼程序實現的模型, 并用流程圖表示了程序的設計過程，用keil c51設計了簡潔的紅外接收程序。信號經單片機解碼處理后經PO口輸送當液晶屏顯示。

ABSTRACT
Infrared remote control is widely used in household appliances and instruments, because of infrared devices with small size, low power consumption, functionality and low cost series of advantages, which in TV, audio equipment, air conditioning and other electrical devices and toys are also have used infrared system. In the industrial field, using infrared equipment to transmit a very wide range of infrared remote control is not only safe, reliable and no electrical interference.    Introduced Silan 6122 infrared remote control chips are used in the understanding of the emission pulse waveform coding, the design of AT89C52 microcontroller based infrared remote control decoder implements a use of MCS-51 Microcontroller external interrupt infrared remote control receiver, focusing on the infrared remote control decoding process realization, and the pattern is analyzed to determine the decoding process to achieve the model, and that the process flowchart design process, design a simple to use keil c51 infrared receiver program . After decoding the signal by the microcontroller through P0 oral delivery LCD screen display.
