基于單片機(jī)的磁懸浮小球控制系統(tǒng)設(shè)計(jì)畢業(yè)論文-全文預(yù)覽
【正文】 力，技術(shù)上已趨成熟，已具有建造運(yùn)營線路的水平。隨著技術(shù)的發(fā)展，特別是固體電子學(xué)的出現(xiàn)，使原來十分龐大的控制設(shè)備變得十分輕巧，這就給磁懸浮列車技術(shù)提供了實(shí) 現(xiàn)的可能。 而 工業(yè)上得到廣泛應(yīng)用的基本上都是傳統(tǒng)的磁懸浮軸承 (需要位置傳感器的磁懸 浮軸承 )，這種軸承需要 5個(gè)或 10個(gè)非接觸式位置傳感器來檢測轉(zhuǎn)子的位移。 ”在談到滬杭磁懸浮建設(shè)的意義時(shí)，同濟(jì)大學(xué)孫章教授如是表示。將一個(gè)金屬樣品放置在通有高頻電流的線圈上時(shí)，高頻電磁場會(huì)在金屬材料表面產(chǎn)生一高頻渦流，這一高頻渦流與外磁場相互作用，使金屬樣品受到一個(gè)洛淪茲力的作用。利用磁力使物體處于無接觸懸浮狀態(tài)的設(shè)想是人類一個(gè)古老的夢，但實(shí)現(xiàn)起來并不容易。 軟件流程圖 ....................................................................... 16 167。 工作原理 ..................................................................................... 7 第 3 章 系統(tǒng)硬件電路的設(shè)計(jì) .................................................................. 8 167。 設(shè)計(jì)內(nèi)容與設(shè)計(jì)方法 ................................................................. 6 167。 第 1 章 緒論 .............................................................................................. 4 167。這個(gè)懸浮裝置的原理是利用對(duì)電磁鐵電流的控制來實(shí)現(xiàn)一個(gè)鐵球 在空中的來回反復(fù)運(yùn)動(dòng)，達(dá)到視覺上的懸浮效果。常導(dǎo)磁懸浮可以分為應(yīng)用電磁鐵的磁懸浮和引用非電磁性磁鐵（ 稀土 永磁鐵、普通磁鐵等）的磁懸浮。 超導(dǎo)磁懸浮是利用處于超導(dǎo)狀態(tài)下的超導(dǎo)體具有斥磁力的原理產(chǎn)生的。河南科技大學(xué)畢業(yè)論文 I 基于單片機(jī)的 磁懸浮小球控制系統(tǒng)設(shè)計(jì) 摘 要 隨著越來越多的磁懸浮技術(shù)應(yīng)用到現(xiàn)實(shí)生活中的各個(gè)領(lǐng)域，磁懸浮這個(gè)在幾年前還是很陌生的一個(gè)詞現(xiàn)在已經(jīng)廣為人知。本文 研究的重點(diǎn)就是這兩種磁懸浮 的控制問題。 與超 導(dǎo)磁懸浮相比，常導(dǎo)磁懸浮的應(yīng)用就更為廣泛，因?yàn)槌?dǎo)磁懸浮的實(shí)現(xiàn)過程要簡單得多。 在本文的最后，我利用在大學(xué)里所學(xué)的知識(shí)，結(jié)合本文的研究重點(diǎn) —— 磁懸浮 裝置的控制問題 ，做出了一個(gè) 簡單的電磁懸 浮裝置。 關(guān) 鍵 詞： 常導(dǎo)磁懸浮，超導(dǎo) 磁懸浮，磁懸浮的控制，演示實(shí)驗(yàn)裝置 ，磁懸浮列車 河南科技大學(xué)畢業(yè)論文 II The design of control system of magic levitation ball based on MCU ABSTRACT As more and more maglev technology is applied to each field in actual life, the word of magic suspension a several years ago was very strange has already widely known by the people. Magic suspension is classified and can be divided into superconductive magic suspension and electromagic magic suspension from the material which produces lift force. It is a very plicated problem to control the magism suspension system. The focal point that this text studies is that these two kinds of magic suspension demonstrate the design about question of controlling of the experimental provision. Superconductive magic suspension is to utilize the superconductor in superconductive state to upbraid magic force principles. To suspend object superconductor,so superconductive control focal point of magic suspension drop on the superconductor superconductive magic suspension. This text is from remend that the using basically of superconductive magic suspension is started with, introduce the basic physical property of the superconductor , then the control method , course and principle to introduce superconductive magic suspension deeply progressively. Compared with superconductive magic suspension, the application that electromagic magic suspension is much more extensive , because the realization course that electromagic magic suspension is much simpler. Magic suspension that electromagic magic suspension and can be divided into the magic suspension which use the electromag and quoted the non electric magic mag (tombarthite permanent mag, ordinary mag ,etc. ). But because the electromag is more convenient and utilizes controlling, it is more extensive to use the magic suspension of the electromag. The research in electromagic magic suspension 河南科技大學(xué)畢業(yè)論文 III of this text is to proceed with a instance , analyse that according to the principle of electromag type magic suspension , thus study electromagic type ma gic suspension control method , course and principle further. At the end of this text, I utilize knowledge studied in the university, bine the research focal point of this text Demonstrate the control question of the experimental provision , has made a simple electric magic suspension device in magic suspension. The principle of the device is to make use of control on electromag electric current to realize moving repeatedly back and forth in the sky of an iron plate that this suspends, reach the result of suspending on the vision . This is it control square different principle to suspend with real electromag, simple means this can achieve the the same goal too. This instance has given us one to enlighten: The simple demonstration experimental provision can state the operation principle of new and high technology , such as maglev train ,etc. too, magic suspension is not out of reach. KEY WORDS： electromagic magic suspension , superconductive magic suspension ,the control of magic suspension,demonstrate the experimental provision, the maglev train 河南科技大學(xué)畢業(yè)論文 IV 目 錄 前 言 ........................................................................ 錯(cuò)誤 !未定義書簽。 發(fā)展前景 .............................................................................. 4 第 2 章 系統(tǒng)總體設(shè)計(jì)與工作原理 ........
