VisualC++6.0編譯器四、系統(tǒng)功能與設(shè)計(jì)要求1．基本功能要求具有友好的人機(jī)交互界面，通過(guò)鼠標(biāo)或鍵盤(pán)，選擇相關(guān)按鈕對(duì)系統(tǒng)進(jìn)行監(jiān)控，監(jiān)控系統(tǒng)具有轉(zhuǎn)速參數(shù)設(shè)置窗口、采樣的電機(jī)轉(zhuǎn)速數(shù)據(jù)顯示窗口和強(qiáng)行干預(yù)系統(tǒng)運(yùn)行的按鈕或相應(yīng)功能選擇菜單。監(jiān)控程序用查詢(xún)（或中斷）方式獲取轉(zhuǎn)速數(shù)據(jù)。直流電機(jī)轉(zhuǎn)速測(cè)量與控制監(jiān)控界面圖屏幕監(jiān)控界面參考上面界面圖，也可以自行設(shè)計(jì)界面風(fēng)格。首先自行設(shè)定轉(zhuǎn)速（小于3000r/m）,點(diǎn)擊“啟動(dòng)”后電機(jī)開(kāi)始運(yùn)轉(zhuǎn)，同時(shí)進(jìn)行數(shù)據(jù)采集，采集到的數(shù)據(jù)（實(shí)測(cè)轉(zhuǎn)速和運(yùn)行時(shí)間）實(shí)時(shí)顯示在相關(guān)位置，點(diǎn)擊“停止”后立刻停止電機(jī)轉(zhuǎn)動(dòng)，同時(shí)停止采集數(shù)據(jù)的輸出，重新設(shè)定轉(zhuǎn)速波形后，再次點(diǎn)擊“啟動(dòng)”即顯示新數(shù)據(jù)。五、設(shè)計(jì)思路用數(shù)字信號(hào)來(lái)控制模擬量的應(yīng)用很多，PWM就是其中一種方法。直流電機(jī)的轉(zhuǎn)速可以由加到（IN）口的脈沖占空比決定，正向占空比越大則轉(zhuǎn)速越快，反之則越慢，其原理圖如下：直流電機(jī)在控制脈沖作用下轉(zhuǎn)動(dòng)，電機(jī)轉(zhuǎn)盤(pán)上的永久磁鐵隨之旋轉(zhuǎn)，霍爾傳感器件3101T受磁場(chǎng)的影響，從端口OUT輸出脈沖信號(hào)，電機(jī)旋轉(zhuǎn)一圈，霍爾傳感器輸出一個(gè)脈沖，通過(guò)測(cè)出脈沖信號(hào)的頻率（單位時(shí)間脈沖個(gè)數(shù)）就可以計(jì)算出電機(jī)的轉(zhuǎn)速利用實(shí)驗(yàn)系統(tǒng)資源可以設(shè)計(jì)一個(gè)直流電機(jī)轉(zhuǎn)速閉環(huán)控制系統(tǒng)。利用帶鎖存的I/O接口電路(如8255,74LS273，D/A-DA0832)輸出控制電機(jī)轉(zhuǎn)速的脈沖。采樣轉(zhuǎn)速用霍爾傳感器件提供電機(jī)轉(zhuǎn)速脈沖。利用定時(shí)/計(jì)數(shù)電路對(duì)電機(jī)轉(zhuǎn)速脈沖計(jì)數(shù)。微機(jī)可從定時(shí)/計(jì)數(shù)電路中獲得電機(jī)轉(zhuǎn)速數(shù)值，并產(chǎn)生控制電機(jī)轉(zhuǎn)速的PWM脈沖。六、心得體會(huì)本實(shí)驗(yàn)將8253的功能運(yùn)用到了極致，并且是一個(gè)閉環(huán)式的實(shí)驗(yàn)。雖說(shuō)我們的實(shí)驗(yàn)是最難的一個(gè)，但是世上無(wú)難事只怕有心人，我們組經(jīng)過(guò)共同討論，分工合作終于將實(shí)驗(yàn)的基本要求完成。作為軟件組的組長(zhǎng)，我再一次深入的學(xué)習(xí)了MFC的窗口控制程序，通過(guò)網(wǎng)絡(luò)學(xué)到了新的控件和函數(shù)的功能。我構(gòu)造了整個(gè)軟件的大框架，而且分工完成了各個(gè)部分的代碼，幫助我們組高效的完成了實(shí)驗(yàn)，并且承擔(dān)了整個(gè)代碼的調(diào)試工作，使代碼從設(shè)想轉(zhuǎn)化為現(xiàn)實(shí)。開(kāi)始時(shí)，我們嘗試了用軟件控制計(jì)數(shù)器定時(shí)器的方式編程，硬件電路簡(jiǎn)單，結(jié)果因?yàn)閷?shí)力有限沒(méi)有成功，最后只有改變硬件線(xiàn)路，減輕了軟件部分的控制負(fù)擔(dān)，使軟件部分能更快的完成任務(wù)，我深刻的認(rèn)識(shí)到做好一個(gè)小項(xiàng)目必須有統(tǒng)籌全局的能力，只有好的硬件設(shè)計(jì)才能減輕軟件的難度，讓程序簡(jiǎn)單化。只有軟硬結(jié)合才是王道。實(shí)驗(yàn)中計(jì)數(shù)器的初始化是個(gè)難點(diǎn)，但是我們共同討論，確定了可行的方案，最終解決了問(wèn)題，并且將微機(jī)原理的理論知識(shí)運(yùn)用到了實(shí)際中，提高了我的動(dòng)手能力。七、附錄實(shí)驗(yàn)代碼：#ifndefPCI9052DLL_H_#definePCI9052DLL_H_boolOpenDevice(void);voidCloseDevice(void);boolGetIoBase(unsignedshort*pusIoBase);boolInByte(unsignedshortusIoAddr,unsignedchar*pucIoData);boolOutByte(unsignedshortusIoAddr,unsignedcharucIoData);#endif////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////#defineIDC_BUTTON_BEGIN1000#defineIDC_BUTTON_STOP1001#defineIDC_EDIT_SETTING_SPEED1002#defineIDC_EDIT_X1003#defineIDC_EDIT_SAMPLE_SPEED1007#defineIDC_EDIT_RUMTIME1008#defineIDC_EDIT_SAMPLE_DUTYCYCLE1009#defineIDC_EDIT_STATE1010#defineIDC_EDIT_Y1011//Nextdefaultvaluesfornewobjects//#ifdefAPSTUDIO_INVOKED#ifndefAPSTUDIO_READONLY_SYMBOLS#define_APS_NEXT_RESOURCE_VALUE130#define_APS_NEXT_COMMAND_VALUE32771#define_APS_NEXT_CONTROL_VALUE1004#define_APS_NEXT_SYMED_VALUE101#endif#endif//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////StdA//stdafx.h:includefileforstandardsystemincludefiles,//orprojectspecificincludefilesthatareusedfrequently,but//arechangedinfrequently//#if!defined(AFX_STDAFX_H__F7778614_97E8_4AC7_9862_4D48CE9CCC55__INCLUDED_)#defineAFX_STDAFX_H__F7778614_97E8_4AC7_9862_4D48CE9CCC55__INCLUDED_#if_MSC_VER>1000#pragmaonce#endif//_MSC_VER>1000#defineVC_EXTRALEAN
