The control of Electronic Communication
With computer technology, communications technology, the rapid development of integrated circuit technology to all-digital fieldbus-represented on-site control instruments, equipment, a large number of applications, the traditional site of the control technology and control equipment at the scene has changed dramatically. The site was cumbersome to connect a single simple field bus network in place of the system design flexibility, easy maintenance, quality of the signal tran**ission is also greatly enhanced, in order to control the on-site industrial users tremendous advantages. After a long period of development, has become Hart, Lonworks, Profibus, Bitbus and a variety of on-site, such as CAN bus protocol.
With the rapid development of electronic technology in the car and on the wider use of electronic vehicle becoming more, especially micro-controller into the car in the field of control, to the development of the automobile has brought epoch-making changes in the car driving force, Stability operations, safety, fuel economy, environmental friendliness have been increased dramatically.
The application of a large number of electronic devices, wiring body is bound to lead to the more complicated the longer run to reduce the reliability, fault repairs difficult. In particular the electronic control unit of the large scale introduction, in order to raise the utilization rate of the signal, a large number of requests for information in various electronic units shared, integrated vehicle control system in a large number of control signals need to exchange real-time, Cambodia has been far from the traditional line This can not meet the demand. In response to these problems, the choice of network technology in computer network technology from the scene and control technology on the basis of the development of the automobile environment applies to all kinds of car networking technology.
And other on-site control, the car temperature range (-45-100 ℃), electromagnetic interference and other electronic noise-keung, environment, network reliability in the operation of the car is especially important that this not only reflected in the structure of the network itself The fault-tolerance and anti-interference ability, but also in the signal encoding and tran**ission methods. Automotive LAN, without exception, have adopted a serial synchronous tran**ission, data and the PWM signal the use of NRZ encoding, bit rate is usually higher than that of NRZ encoded using 100kbps, which is lower than 100kbps encoding using PWM.
Many well-known international car company in the early 80's on the active network dedicated to automotive technology research and application. To date, a variety of network standards such as SAE's J1850, Germany's public ABUS, the Bosch CAN, the American Business Machines AutoCAN, ISO's VAN, such as Mazda's PALMNET.
In accordance with China's automotive electronics technology development planning, into the 21st century car electronics up to the level of 90 foreign countries, will also be a large number of intelligent electronic control unit was introduced. To shorten the car with foreign skills, improve their own competitiveness, relying on technology alone is not conducive to long-term growth, digestion, absorption, research and development of its own network of automotive applications is imperative
在演讲前多背几篇精彩英文演讲稿是非常有必要的，下面我就分享几篇给你们，希望对你们有用。
篇一
good afternoon ，ladies and gentlemen!
i’m very honored to stand here and give you a short speech! to begin with ,i want to ask a question .does everybody dream a good dream last night? actually ,today i want to talk about dream with you. of course, what i want to talk is not a dream you have last night,but a dream—— about life.
everyone has dreams about life, different dreams at different life stage,and we need dreams to support us. dreams are like the stars we never reach in the sky,but like most mariners水手,we can chart our course by them. with the dream,we have a direction,with a direction, we were no longer confused.with the dream, there is hope,with hope, we have the strength to fight.
i have a dream: to be a doctor.，because doctor may relieve the pain of patients. may let the human change the health. at the same time, i believed that, those who help others may be able to obtain joyfully. therefore, i hoped in the near future ,i might be a doctor.
but i know，life is tough,and there are always ups and downs, maybe we fail in the way to our aims,and we may feel depressed ,whenever at this time, the dream in our heart can always fort us, encourage us ,and support us to move ahead .
young!fortunately, i am young now. just due to it, i know that nothing is impossible.i firmly believe that nothing can stand in my way. if i can't realize my dream,it result from that i haven't work harder enough and i won't find other excuses. if no people believe you, you can make it to prove that you are right. if you think the god haven't blessed you and there is no truth here, you can bee the god and create the truth.
"my breath swallows the sky and make the yellow river overflow, my sword is famous in kyushu and it can collapse the five sacred mountains." at some time in the past i also had am bitious words and i had some achievements. each achievement results from my hard work. i always believe that "if you want to have more achievements than others, you must work harder." in some extent, the dream is the hope. if you can insist on doing something, the victory will e.
hold fast to dreams, for if dreams die, life is a broken-winged bird that cannot fly. hold fast to dreams, for when dreams go, life is a barren field frozen with snow. so my dear friends, think of your old and maybe dead dreams. whatever it is, pick it up and make it alive from today. let's--- move ----out!
thank you for your listening!
篇二
everyone has his ownunderstanding of young,it is a period of time of beauty and wonders,only after you have
experienced the sour ,sweet ,bitter and salty can you really bee a person of significance.thre time of young is limitted,it may paby without your attention,and when you discover what has happened ,it is always too late.grasping the young well means a better time is waiting for you in the near future,or the situation may be opposite .
having a view on these great men in the history of hunmanbeing,they all made full use of their youth time ,to do things that are useful to society,to the whole mankind,and as a cosquencyanjianggao/e ,they are remembered by later
generations,admired by everyone.so do something in the time of young,although you may not get achievements as these greatmen did ,though not for the whole word,just for youeself,for those around!
the young is just like blooming flowers,they are so beautiful when blooming,they make people feel happy,but with time passing by,after they withers ,moet people think they are ugly.and so it is the same with young,we are enthusiastic when we are young,then we may lose our passion when getting older and older.so we must treasure it ,don't let the limitted time paby ,leaving nothing of significance.
as you slowly open your eyes, look around, notice where the light es into your room; listen carefully, see if there are new sounds you can recognize; feel with your body and spirit, and see if you can sense the freshnein the air.
yes, yes, yes, it’s a new day, it’s a different day, and it’s a bright day! and most importantly, it’s a new beginning for your life, a beginning where you are going to make new decisions, take new actions, make new friends, and take your life to a totally unprecedented空前的 level.
in your mind’s eye, you can see clearly the things you want to have, the paces you intend to go, the relationships you desire to develop, and the positions you aspire励志 to reach.
you can hear your laughters of joy and happineon the day when everything happens as you dream. you can see the *** iles on the people around you when the magic moment strikes. you can feel your face is getting red, your heart is beating fast, and your blood is rushing all over your body, to every single corner of your being!
you know all this is real as long as you are confident, passionate and mitted!效忠的 and you are confident, you are passionate, you are mitted!
you will no longer fear ma-ki-ng new sounds, showing new facial expressions, using your body in new ways, approaching new people, and asking new questions.
you will live every single day of your life with absolute passion, and you will show your passion through the words you speak and the actions you take.
篇三
today i am very glad to be here to share with you my ideas of success. what is success? it is what everyone is longing for.sometimes success would be rather simple. winning a game is success; getting a high grade in the exam is success; making a new friend is success; even now i am standing here giving my speech is somehow also success.
however, as a person's whole life is concerned, success bees very plicated. is fortune success? is fame success? is high social status success? no, i don’t think so. i believe success is the realization of people's hopes and ideals.nowadays, in the modern society there are many people who are regarded as the successful. and the most obvious characteristics of them are money, high position and luxurious life. so most people believe that s success and all that they do is for this purpose. but the problem is wether it is real success. we all know there are always more money, higher position and better condition in front of us. if we keep chasing them, where is the end? what will satisfy us at last? therefore, we can see, to get the real success we must need something inside, which is the realization of people's hopes and ideals.
different people have different ideas about success; cause people's hopes and ideas vary from one another. but i am sure every success is dear to everybody, cause it is not easy to e by, cause in the process of our striving for success, we got both our body and soul tempted, meanwhile we are enlightened by the most valuable qualities of human beings: love, patient, courage and sense of responsibility. these are the best treasures. so now i am very proud that i have this opportunity to stand here speaking to all of you. it is my success, cause i raise up to challenge my hope.
what is success? everyone has his own interpretation as i do. but i am sure every success leads to an ever-brighter future. so ladies and gentlemen, believe in our hopes, believe in ourselves, we, every one of us, can make a successful life!
wish you all good success!

(Modern Technology Makes Life More Convenient)
Modern technology makes life more convenient; tools are the milestores of the technology as well as human being’ s progress.
Men used to cut trees with hand saw. But now, by using electronic saw they can cut down a tree in only a few minutes. Another example is more vivid: You have something urgent which has to be informed to your friend whose house is two hour’s ride away. You probably want to make a phone call. But no telephone is installed in your friend’ s home. What could you do? Nowadays, with modern technology advanting, using internet is popular with us. Some years ago, people had to get what they wanted through looking into a lot of information; at last people could become tired and spent too much time. Now, if you use Internet, all becomes a piece of cake. Only by clucking, you will gain what you expect.
We all hope that modern technology will reach a higher level, because modern technology makes life more convenient indeed.

现代科技使生活更加便捷
现代科技使生活更加便捷；工具是科技进步和人类进步的里程碑。人类过去用手锯锯树，但是现在，用电锯可在几分钟内锯倒一棵树。另外一个例子更加生动形象：如果你有急事通知你的朋友，而他家距你家有2小时的路程，你可能想打个电话。但是你的朋友家又没安电话，你该怎么办?如今，随着现代科技的进步，使用网络已很流行。若干年前，人们不得不查找大量资料来搜集需要的信息，最后人累得疲惫不堪，还浪费了大量时间。现在，如果使用网络，一切就都是小菜一碟了。只要轻敲键盘，就会有求必应。
我们都期待着现代科技能达到一个更高的水平，因为现代科技确实使生活变得更便捷。
开头：Ladies and Gentlemen , Good afternoon! I’m very glad to stand here and give you a short speech.Today my topic is “xxx”and? I hope you will like it.
