【正文】 海 南 大 學本科生畢業(yè)論文（設計）題 目: 智能紅外線家電遙控系統(tǒng)的設計 / 34摘 要 家電產(chǎn)品幾乎都具備有 紅外線遙控功能，人們也早已習慣按遙控器的動作，桌上擺滿了各式紅外線遙控器也是常有的事，而這些遙控器也只能 控制本身家電用品，本系統(tǒng)特別設計一個接收器，可接收這些遙控器的控制碼，并達到控制繼電器 ON/OFF 輸出的目的，使這些遙控器又增添一項用途。在系統(tǒng)中以紅外線傳輸為主要媒介，對現(xiàn)有紅外線遙控開關的產(chǎn)品的紅外發(fā)射碼進行分析，并藉由單片機系統(tǒng)進行解碼，同時提供二個通道的控制 ，并提供兩 AC 負載插座共 1500W 的輸出控制。 為了讓使用者方便操作本系統(tǒng)，系統(tǒng)分成電源供應模組及微電腦控制接收模組，兩模塊間以一條纜線連接。本系統(tǒng)藉由紅外線接收感測元件接收遙控器的發(fā)射碼，經(jīng)由 89C51 的處理后，可以控制電源供應模塊上的兩個插座通道的接通或關閉。關鍵詞： 紅外線；單片機；89C51；繼電器；遙控器I / 34Abstract Most of the household appliances in the market are equipped with infrared remote control. People accustom to turn on and off appliances with this device. People have their living rooms littered with remote controls. However, each remote control can only manipulate a single appliance that they are designated for. We have designed a special infrared receiver in this research which can receive the control codes in order to turn on and off a control relay. In this system that we designed, analyse signals emit from infrared remote and decode by SCM. The controller also provides two AC overload sockets with 1500W output control. In order for user to easily learn how to manipulate this system, we separated this system into two parts: a power supply module and a microputer controlling receiver module. An wire links both modules together. After an infrared receiver detects an ining signal, through 89C51, we can manipulate the current flows to either one of the sockets.
