試驗(yàn)二電氣裝備計(jì)算機(jī)控制系統(tǒng)設(shè)計(jì)

一、試驗(yàn)?zāi)康?/p>

1、理解數(shù)據(jù)采集系統(tǒng)的I硬件原理,理解數(shù)據(jù)采集卡的技術(shù)指標(biāo)和驅(qū)動(dòng)函數(shù)；

2、掌握PCI1202數(shù)據(jù)采集卡獲取數(shù)據(jù)口勺措施，數(shù)據(jù)采集軟件編寫的措施；

3、掌握計(jì)算機(jī)控制技術(shù)，學(xué)會電氣裝備計(jì)算機(jī)控制系統(tǒng)的軟件和硬件設(shè)計(jì)，熟悉控制系統(tǒng)

日勺調(diào)試措施。

二、試驗(yàn)內(nèi)容

I、使用數(shù)據(jù)采集系統(tǒng)進(jìn)行各路數(shù)據(jù)采集，對數(shù)據(jù)采集的成果進(jìn)行記錄和分析；

2、運(yùn)用采集卡數(shù)據(jù)輸入輸出功能設(shè)計(jì)一種簡易控制三相異步電機(jī)正反轉(zhuǎn)的控制系統(tǒng)。

三、試驗(yàn)原理

在電氣裝備等各個(gè)應(yīng)用領(lǐng)域都存在著數(shù)據(jù)采集、存儲、處理與控制問題，常常需要對電

流、電壓、溫度、壓力、流量、位移等模擬量進(jìn)行采集，通過模/數(shù)（A/D）轉(zhuǎn)換，數(shù)據(jù)處

理，最終把成果顯示出來或者進(jìn)行對應(yīng)的控制處理。

數(shù)據(jù)采集系統(tǒng)口勺信號采集部分一股包括信號輸入和調(diào)理（信號衰減/放大與濾波）、采樣

/保持、模/數(shù)（A/D）轉(zhuǎn)換、數(shù)據(jù)存儲（RAM）等，再通過接口傳播到計(jì)算機(jī)，由計(jì)算機(jī)進(jìn)

行信號的分析處理和顯示，

三相異步電機(jī)的轉(zhuǎn)子是被定子H勺三相繞組通入三相交流電產(chǎn)生的旋轉(zhuǎn)磁場拖動(dòng)的，三相

繞組合成I內(nèi)旋轉(zhuǎn)磁場向哪個(gè)方向轉(zhuǎn)，轉(zhuǎn)子就向哪個(gè)方向轉(zhuǎn)。因此，只要將三相電源線的任意

兩根線換接，電機(jī)定子的旋轉(zhuǎn)磁場就被變化廣，那么電機(jī)轉(zhuǎn)子的轉(zhuǎn)動(dòng)方向也將跟隨旋轉(zhuǎn)磁場

的方向變化。

TForm1*Form1;

WordTotalBoards;

闡明：該程序段包括有關(guān)頭文獻(xiàn)闡明與編譯預(yù)處理指令，同步定義Word型變量Tota舊oards,

用于計(jì)數(shù)板卡總數(shù)。

程序段②

if(TotalBoards<2)〃若板卡數(shù)少于2,不容許選用

(

)

)

闡明：該程序段為窗口初始化函數(shù)及P1202驅(qū)動(dòng)初始化。首先定義一種Word類型變量

RetValue,然后調(diào)用板卡驅(qū)動(dòng)初始化函數(shù)P1202_Drive而讓()，檢測有幾種板卡，并將宣賦

給變量RetValue,記錄返回值。假如RetValue!=0,即出現(xiàn)錯(cuò)誤代碼，則顯示錯(cuò)誤信息，

其中包括IntToStr。函數(shù)調(diào)用，用于將檢測到的總板卡數(shù)轉(zhuǎn)換為字符串顯示，同步按鈕

Buttonl不使能。eSelect->Text用于板卡選擇，初始值賦為0表達(dá)從。開始計(jì)數(shù)，即0表達(dá)第

一種板EeTotal-Text用于記錄一共有多少板卡，所賦值為實(shí)際板K總數(shù)。UpDown1->Max

用于記錄板卡數(shù)計(jì)數(shù)最大數(shù)。UpDown1->Min用于記錄板k計(jì)數(shù)最小值，為0。假如板k總

數(shù)少于2,則不容許選用。
