畢業設計--基于pic單片機的步進電機控制系統設計-資料下載頁

【導讀】有快速啟動和停止的特點。其驅動速度和指令脈沖能嚴格同步，能實現正反轉和。平滑速度調節，因而被廣泛應用于數模轉換，速度控制和位置控制系統。靈活性和可靠性。尤其在一些智能化要求較高的場合，用模擬芯片及信號發生器。來控制步進電機有一定的局限。電路也比較簡單，因此在工業應用場合，基于單片機的步進電機控制器應用廣泛。件相結合的控制方法。用軟件代替脈沖分配器，達到了對步進電機的最佳控制。采用單極性驅動電路對小功率步進電機進行驅動，電路簡單，實用性好。顯示屏對步進電機的預設工作狀態進行動態顯示，直觀、明了。（四）步進電動機的加減速........

　　

【正文】 } 基于 PIC單片機的步進電機控制系統 設計 28 結 論 單片機 控制 系統設計的趨勢為單片化，即盡量發揮單片機的功效，使用盡量少的元器件與連線來構成硬件，通過軟件來實現盡量多的功能。我們設計的 步進電機控制 系統大量使用了同步 并行 總線，簡化了硬件系統的復雜度，同時使用模塊化設計思想提高了軟件的聚合度， 利用按鍵進行設置以及 LCD 顯示屏及時顯示， 實現了軟件編寫簡單，系統直觀易用，突出了在設計時的簡單、易用、 實用性強 的原則。 由于該系統是用于 作為控制步進電機的轉向，轉速等各種狀態 ，所以在實際應用中還有很多需要完善的地方。雖然真正的 高精度 的步進電機 控制系統是相當復雜的，但是我們制作的 控制 系統作為原理性的說明已經足夠了。通過對 步進電機工作參數設置，LCD 顯示，加減速 控制等功能的實現，我們完成了對 單片機控制步進電機 的原理剖析，對 步進電機加減速技術 有了一定了解，加深了對 PIC 單片機應用的認識，掌握了基于單片機的編程思想，為日后走向工作崗位積累了軟件開發設計及硬件制作方面的寶貴經驗。 基于 PIC單片機的步進電機控制系統 設計 29 參考文獻 [1] 許洪斌，杜向 斌 ． 步進電機控制系統設計 [J]． 重慶工學院學報（自然科學） ． 2021，第 22 卷，第 5 期 ） ： 3234． [2] 孟武勝，李亮 ． 基于 AT89C52 單片機的步進電機控制系統設計 [J]． 微電機 ． 2021，第 40 卷，第 3 期）： 6566． [3] 李榮正，劉啟中，陳學軍． PIC 單片機原理及應用（第 2 版） [M]．北京：北京航空航天大學出版社． 2021： 1317． [4] 王曉明 ． 電動機的單片機控制 [M]． 北京：北京航空航天大學出版社， 2021： 181214． [5] 徐國山，潘振良 ． 步進電機的基本原理 [J]． 科技論壇 ， 2021，第 7 期）： 9． [6] 孫建忠，白鳳仙 ． 特種電機及其控制 [M]． 北京：中國水利水電出版社， 2021： 147178． [7] 李曉貞，王福志，王忠舉 ． 基于單片機的步進電機調速研究 [J]． 農業裝備與車輛工程 ． 2021，第 5 期）： 2223． [8] 朱利軍，袁麗娟，王應海 ． 液晶顯示模塊在控制系統中的應用 [J]． 電子技術 ． 2021)： 52． [9] 懷業強，梁健宏 ． HY240128M201 圖形點陣式液晶顯示模塊及其應用 [J]． 電子設計應用 ． 2021，第 3 期）： 136． [10] 金鵬電子有限公司 ． C 系列中文液晶顯示模塊使用說明書 [PDF]． ： //． gptlcm． ． 2021． [11] 田豐國，賀瑩，武 淑娟．基于 PIC16F877A 單片機軟件環分的步進電機控制系統 [J]．電氣技 術2021，第 3 期）： 58． [12] Microchip Technology Inc． PIC16F87X Data Sheet[PDF]． ： //． microchip． ． 2021． [13] 何兵 ． 基于 MCS51 單片機的步進電機正反轉控制實現 [J]． 瀘州職業技術學院學報 ． 2021，第1 期）： 5657． 基于 PIC單片機的步進電機控制系統 設計 30 致謝 感謝 荊剛 老師，他 那嚴謹的治學態度和豐富的實戰經驗永遠是我們學習的榜樣 。在趙 老師這里，正直、誠 信、樂觀、寬博對我們來說不再是簡單的詞匯，對這些我們有了清醒直觀的認識，這是我們寶貴的收獲，在將來的日子里將會使我們受益匪淺。 最后，向各位和我一樣面臨就業或考研壓力卻對我的畢業設計 有所幫助 的同學們表示衷心的感謝，同時也特別感謝學院和學校對我們畢業設計的大力支持。 g an employment tribunal clai Employment tribunals sort out disagreements between employers and employees. You may need to make a claim to an employment tribunal if: ? you don39。t agree with the disciplinary action your employer has taken against you ? your employer dismisses you and you think that you have been dismissed unfairly. For more information about dismissal and unfair dismissal, see Dismissal. You can make a claim to an employment tribunal, even if you haven39。t appealed against the disciplinary action your employer has taken against you. However, if you win your case, the tribunal may reduce any pensation awarded to you as a result of your failure to appeal. Remember that in most cases you must make an application to an employment tribunal within three months of the date when the event you are plaining about happened. If your application is received after this time limit, the tribunal will not usually accept i. If you are worried about how the time limits apply to you, take advice from one of the anisations listed under Further help. Employment tribunals are less formal than some other courts, but it is still a legal process and you will need to give evidence under an oath or affirmation. Most people find making a claim to an employment tribunal challenging. If you are thinking about making a claim to an employment tribunal, you should get help straight away from one of the anisations listed under Further help. If you are being represented by a solicitor at the tribunal, they may ask you to sign an agreement where you pay their fee out of your pensation if you win the case. This is known as a damagesbased agreement. In England and Wales, your solicitor can39。t charge you more than 35% of your pensation if you win the case. If you are thinking about signing up for a damagesbased agreement, you should make sure you39。re clear about the terms of the agreement. It might be best to get advice from an experienced adviser, for example, at a Citizens Advice Bureau. To find your nearest CAB, including those that give advice by , click on nearest CAB.

Uefa has opened disciplinary proceedings against CSKA for the racist behaviour of their fans during City39。s 21 win. Michel Platini, president of European football39。s governing body, has also ordered an immediate investigation into the referee39。s actions. CSKA said they were surprised and disappointed by Toure39。s plaint. In a statement the Russian side added: We found no racist insults from fans of CSKA.
