Infrared remote control technology, not only greatly improve the labor productivity, reduces the cost, but also reduces the labor intensity, improve working conditions. Infrared remote control device , strong function, low cost and thus become a kind of control method of todays very popular. This design mainly adopts single-chip computer AT89C51 as the core component design, the design of a multi-channel infrared remote control transmitting receiving system. The design of the infrared transmission of information as a carrier, can be a short distance wireless control of 4 controlled object working state, can count on the equipment is in working state, and displayed. Opening and closing state suitable for remote control of industrial, medical, , short distance control, equipment 目录  TOC \o 1-3 \h \z \u 第1章 绪论  PAGEREF _Toc356762226 \h 1 1.1选题的目的意义  PAGEREF _Toc356762227 \h 1 1.2红外遥控简介  PAGEREF _Toc356762228 \h 1 1.3红外遥控研究现状和成果  PAGEREF _Toc356762229 \h 2 第2章 总体方案设计  PAGEREF _Toc356762230 \h 5 2.1设计方案  PAGEREF _Toc356762231 \h 5 2.2系统设计思路  PAGEREF _Toc356762232 \h 7 第3章 硬件电路设计  PAGEREF _Toc356762233 \h 8 3.1元器件选择  PAGEREF _Toc356762234 \h 8 3.1.1主控芯片AT89C51单片机的简介  PAGEREF _Toc356762235 \h 8 3.1.2红外一体化接收头HS0038简介  PAGEREF _Toc356762236 \h 11 3.2发射电路部分  PAGEREF _Toc356762237 \h 12 3.2.1按键控制电路  PAGEREF _Toc356762238 \h 12 3.2.2红外发射电路  PAGEREF _Toc356762239 \h 12 3.3接收电路部分  PAGEREF _Toc356762240 \h 13 3.3.1电源电路  PAGEREF _Toc356762241 \h 13 3.3.2红外接收电路  PAGEREF _Toc356762242 \h 14 3.3.3数
