【正文】 I AbstractInfrared ray is close, a means of highspeed wireless munication, as a kind of close, indoor means of munication, infrared has inparable advantage over radio.System is introduced in this paper by using the infrared munication channel constitute the infrared wireless shortrange equipment control system, can meet the needs of the wireless control. This article mainly expounds the working principle and implementation method of infrared munication, infrared wireless munication process, a detailed analysis of each module of the system design, the best scheme of this system are derived, successfully pleted the design of the system. This system is divided into three modules: voice module, the infrared emission module, the infrared receiving module. Power supply module adopts the 7805 of 5 v power supply. mainly used in infrared emission module triode, LM386 will receive the signal voltage amplifier and power amplifier and infrared transmitting tube. Mainly used in infrared receiving module triode, LM386 will receive the signal voltage amplifier and power amplifier and infrared receiving tube. The function of system implementation is the use of infrared lightemitting tube as the transceiver devices and infrared receiving module, transmission distance is 2 meters.keyword: Infrared Diodes Infrared Receiving Tube Set The Audio Power Amplifier目 錄 摘 要 IAbstract II第一章 總體設計方案 1 紅外通信的發(fā)展背景 1 總體設計方案 2 電源模塊模塊論證與選擇 2 紅外光發(fā)射模塊論證與選擇 3 系統(tǒng)各模塊的最終方案 4第二章 電路的設計 5 總體系統(tǒng)電路的設計 5 各個模塊的電路設計 6 電源模塊功能介紹 6 紅外光發(fā)射模塊功能介紹 6 紅外光接收模塊功能介紹 7 電路參數(shù)的計算及元器件的選擇 8 電路參數(shù)的計算 8 元器件的選擇 8 特殊器件的介紹 9 各模塊的連接 11第三章 測試方案與測試結果 13 測試方案 13 測試儀器 13 測試結果及分析 13 測試結果 13 測試分析與結論 14第四章 設計總結 15第五章 心得體會 16參考文獻 17附錄一 系統(tǒng)實物圖 18附錄二 系統(tǒng)電路圖 20III第一章 總體設計方案 紅外通信的發(fā)展背景20世紀80年代人類進入信息時代以來，人們的一切社會活動
