1、 成都信息工程学院通信工程学院本科毕业论文设计 英文中文翻译 论文题目 红外光通信系统设计姓 名 专 业通信工程班 级 学 号 指导教师 日 期2014年 02月 27日 英文原件内容 Introduction Infrared remote control system is mainly composed by the remote control transmitter,integrated receiver head,microcontroller,interface circuit shown in Figure1.The remote control is used to gene

2、rate the remote encoder pulse drive infrared emission control output of the infrared remote control signal,the remote control receiver on the remote control signal amplification,detection,shaping,demodulation remote encoder pulse.The remote control encoder pulse is a serial binary code for the infra

3、red remote control system,the serial code input to the microcontroller,its internal CPU instruction decode on the remote control,and perform remote control functions.Using the remote control as the input of the control system,we need to address the following key questions: how to receive the infrare

4、d remote control signal;how to identify the infrared remote control signal,and decoding software design,design of control procedures.SCM history SCM was born in1971,has gone through three major phases of the SCM,the MCU SoC.It consists of computing device,controller,memory,input output devices.Its f

5、ull name is a single-chip microcomputer,is typical of embedded micro-controller (Microcontroller Unit),the commonly used letters of the abbreviation MCU single-chip,and it was first used in the field of industrial control.Master microcontroller technology to enable more people in the industry,studen

6、ts,enthusiasts,product developers,the question arose due to the extensive application of SCM in the field of industrial control,microcontroller development board,the more famous such as e-DZR-01A microcontroller development board.Microcontroller chip dedicated processor developed from the CPU.The fi

7、rst design concept by a large number of peripherals and CPU integrated in a single chip,the computer system is smaller,more easily integrated into complex and require strict control equipment on the volume.Single-chip,also known as single-chip microcontroller,it is not the completion of a logical fu

8、nction of the chip,but a computer system integrated onto one chip.Equivalent to a mini-computer and computer,microcontroller only the lack of I / O devices.SCM rely on the program is running,and can be modified.Different functions through different programs,especially the special unique function,whi

9、ch is the other devices require much effort to do,while others make great efforts it is difficult to do.A not very complex functions using pure hardware to get the words of the1950s developed74series,or60during the CD4000series,the circuit must be a big PCB board!If successful on the market in the U

10、nited States in the1970s series of microcontrollers,the result will be different!Just because a program written by the MCU through you can achieve high intelligence,high efficiency and high reliability! Microcontroller for cost sensitive,so accounting for the dominance of the software or the lowest

11、level assembly language,which is the lowest level than binary machine code language,since such low-level why use it?A lot of high-level language has reached a level of visual programming,why not?The reason is simple,is the microcontroller does not have a home computer as the CPU,also not as hard as

12、mass storage devices.A visual high-level language to write small programs inside even if there is only one button,will reach tens of K of size!Nothing in terms of home PCs hard drive,but for SCM in terms of is not acceptable.SCM in the utilization of hardware resources must be high,so the compilatio

13、n of the original while still in heavy use.The same reason,if the computer giants operating system and application software to get home PC run up to the home PC can not afford. It can be said that the twentieth century across the threepowerera of the electrical era,the electronic age and has now ent

14、ered the computer age.However,such a computer,usually refers to a personal computer,or PC.It is by the host,keyboard,monitor,and so on.Another type of computer,not how most people are familiar with.This computer is smart to give a variety of mechanical microcontroller (also known as micro-controller

15、).The name suggests,the smallest of this computer system using only one IC to make a simple calculation and control.Because of its small,usually hidden in a controlled mechanicalstomach.Throughout the device,it plays like the role of the human mind,it is wrong,the entire device was paralyzed.Now,thi

16、s single chip field of use has a very wide,such as smart meters,real-time industrial control,communications equipment,navigation systems,home appliances and so on.A variety of products using the SCM,you can play the effect of product upgrades,often preceded by an adjective in front of the product name -smart,such as smart washing machines.Some factories or other amateur electronics developer
