【正文】 ble 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 III 目 錄 摘 要 I Abstract II 第一章 總體設(shè)計(jì)方案 1 紅外通信的發(fā)展背景 1 總體設(shè)計(jì)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(shè)計(jì) 5 總體系統(tǒng)電路的設(shè)計(jì) 5 各個(gè)模塊的電路設(shè)計(jì) 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(jì)算及元器件的選擇 8 電路參數(shù)的計(jì)算
