【正文】 the Infrared Transmission.I. IntroductionIn medical, it requests the speed of a bit of transfusion to control in certain scope. Traditional transfusion installation in transfusion course, acpanying the liquid unceasing decreasing in transfusion bottle and the transfusion’s speed of a bit unceasing reduction, cannot satisfy medical requirement. This design uses the infrared check installation testing speed of a bit, transformation it to digital signal and inputs SCM. SCM shows it using numberal pipe and at the same time SCM controls walking electrical machine according to design, to make the speed control of a bit in the scope that enactments in advance. To increase systematic practicality, from digital keyboard of SCM, user can municate according to the network and enactment the drop speed of set point by one’s need, can realize transfusion a bit of several wards from control system. It can replace transfusion with existing hospital by the liquid speed supervisory and control arrangement of a bit which have the characteristic with simple control and high precision. There is wide market prospect in the aspect of hospital and family tend, having higher society and economic benefits. It just follows as fig 1:II. Hardware designA. SCM brief introduction: SCM is more called as tiny controller definitely, is 20 century middle of 70 decade development getting up a kind of rule modular of integrated circuit that faces control , its characteristic is function strong , volume little ,reliability is high , price cheap. Once it came forth,it was convenient in industrial control, data collection and intelligence melt the fields such as appearance,electromechanical unifinication and home appliances and have gotten extensive application, also have raised automation level and the technical level of these fields maximally. Therefore application and the development of SCM have bee hightech with asignificant program of project field.B. Walk into generator: It is a kind of conductedelement of digital control system. It can change the digital quantitative change of input, is correspondingangular displacement or the displacement of straight line, make digital signals into pulse signals, give firstly pulse signals, motor turns a angle or ongoingone step. Sketch is :① THE speed inspection of a bit design: It adopts the infrared sensor drop speed of measurement point, project with direct current, circuit is simple , has steady performance. Consideration uses a pair of pipe,lean droplet to fall take off reflection infrared ray will make accept pipe unknown and produce low level signals, but reflection signals is too weak , can not be monitored efficiently.② The speed control: It is fast to set an initial altitude first, and detection drips now. Then, regulate repeatedly, controlling step into the revolution of generator according to the relation between high and drop speed reaching suitable, make droplet satisfy to set drop speed highly.③The high detection of face of blade with alarm: Using infrared detection Technology, realize its warning function. Let infrared transmitting tube with take over pipe just for set up in bottle two side, and set up in the altitude of cordon, because of sensor when having water with sink water receive signals strength difference. Therefore but basis take over the strong weak difference of signals, with parator handling,can get the greater telemunications discrepancy that water level arouses in critical line , and judging from whether water level reaches cordon, SCM sends alarm signal’s.III. Software designSoftware design is systematic crucial link. If hardware is skeleton, software is “muscle and nerve. Software design is mainly with signals and control signal `s outputting, the munication between main station and stations and showing with keyboard’s controlling program. (1) Keyboard with showing is plete modular and the frequency that shows are the things that we will consider, because of having measured the speed of a bit, the frequency that shows can set according to needs pletely. (2) The software about the munication between main station and stations: With relapse test and elaborate design, with the isolation technology of chief line us have realized standing for war all functions, can realize efficiently to stand for the control of station. Major stands to dispatch i。最后，向所有關(guān)心和幫助過我的領(lǐng)導(dǎo)、老師、同學(xué)和朋友表示由衷的謝意！衷心地感謝在百忙之中評閱本人畢業(yè)論文和參加答辯的各位老師！附錄一 中英文技術(shù)資料翻譯英文原文：Design of Realizing the Function of Spot Speed Monitoring and Control Based on SCM TechnologyCHEN Wulin1，YAN Jiansheng1，HUANG Tianchen1，WANG Jianqiang1，TIAN Linghui21Department of Electric Engineering, Ordnance Engineering College, Shijiazhuang 050003, China。田老師嚴謹?shù)慕虒W(xué)態(tài)度，淵博的知識，以及認真工作的態(tài)度使我從田老師那里學(xué)習(xí)到了很多，使我做事更加精益求精，做人更加的踏實，因此我在這里要由衷的感謝田老師的支持幫助，謝謝老師！在畢業(yè)設(shè)計的過程中，我的幾位舍友也給了我很多幫助，不僅給我講解設(shè)計過程中代碼不懂的地方，還給我提出了很多有用的意見，同時也給予了我莫大的鼓勵，使我更加有信心完成本次畢業(yè)設(shè)計。同時田老師也經(jīng)常啟迪我的設(shè)計，使我的設(shè)計更加完善。通過這次畢業(yè)設(shè)計使我明白了付出和回報是成正比的，一分耕耘一分收獲。致 謝歷經(jīng)3個多月的畢業(yè)設(shè)計終于也接近尾聲了，雖然其中經(jīng)歷了很多曲折，但是也終于有了成果，經(jīng)過仿真得到了預(yù)期的結(jié)果，之后經(jīng)過制板得到了實物，完成了預(yù)期的要求。通過這次畢業(yè)設(shè)計，加強了我對單片機知識的了解，同時也豐富了我對單片機應(yīng)用的眼界。當(dāng)然在設(shè)計過程中也遇到過很多問題，比如說到底應(yīng)該把光電傳感器裝在那里，只有經(jīng)過實踐的操作以及查閱資料才能得到更準(zhǔn)確的結(jié)果，總而言之，只要通過對該設(shè)計的慢慢了解，以及學(xué)習(xí)其的相關(guān)知識，總能夠解決問題，出現(xiàn)了問題才能鍛煉我們的實踐能力，因此我覺得錯誤并不可怕，可怕的是不去解決錯誤。當(dāng)然該設(shè)計也能用在工業(yè)等地方，總的來說該設(shè)計是有比較大的使用價值的，因此在設(shè)計的時候也比較令人感興趣。畢業(yè)設(shè)計就是我們檢測大學(xué)四年學(xué)習(xí)的成果，是一次重要的實踐機會。2000[11]陳玨曉，程顯佳，楊雪蓮，薛建飛，[12][J].

S. of interactions of electrons and positrons with matter in MCUPD of Atomic 結(jié)束語經(jīng)過了3個多月的畢業(yè)設(shè)計終于接近尾聲，雖然設(shè)計過程比較艱辛，但是預(yù)期的工作還是如期的完成了。通過改進便可以使系統(tǒng)對速度過快進行報警，也可以對速度過慢進行報警，而且能夠自動調(diào)節(jié)速度到預(yù)定的值，因此智能化水平大大提高。其次對于沒有速度控制裝置，可以使用一個步進電機對滴管速度進行控制，使用步進電機的轉(zhuǎn)動擠壓管子從而改變液體的流動速度。實際應(yīng)用的時候還要根據(jù)液晶屏顯示的當(dāng)前速度來手動調(diào)節(jié)液體點滴的速度。 無速度控制裝置該系統(tǒng)缺少一個速度控制裝置，無法自動改變其速度，因此智能化水平還不夠高。解決方法：主要是把光電傳感器安置在滴管的聚液處，在那里可以檢測一滴滴的液體流過，因此適合計算速度值，也方便累計液體滴數(shù)，而且實際應(yīng)用中也可以節(jié)省藥液。問題二：本次設(shè)計主要存在的問題是不知道到底把光電傳感器裝在滴管還是滴瓶面，后來經(jīng)過仔細，如果裝在滴瓶上面，滴瓶的弧形口不適合裝光電傳感器，即使裝上也不精確，但如果不裝在弧形口，裝在滴瓶中間或者中間一下部分，那么雖然試驗時是可以的，但是在實際
