1、河北工程大學(xué)畢業(yè)設(shè)計(jì)摘要離心式水泵是礦山機(jī)械中廣泛使用的機(jī)械設(shè)備,對(duì)保證礦山生產(chǎn)安全正常地進(jìn)行發(fā)揮著重要的作用。一種準(zhǔn)確方便的水泵檢測設(shè)備對(duì)于煤礦企業(yè)來說是非常重要的。并且對(duì)于保障礦山安全生產(chǎn)具有重要的意義。水泵要測量的主要參數(shù)有流量,水泵轉(zhuǎn)速,電機(jī)轉(zhuǎn)速,電機(jī)功率,電機(jī)電流,水泵軸功率。文中介紹了一種用USB2.0總線技術(shù)解決數(shù)據(jù)采集系統(tǒng)接口題的實(shí)施方案。文中首先深入研究了USB的體系結(jié)構(gòu),然后結(jié)合提出的方案,較為全面地介紹了系統(tǒng)的硬件和軟件設(shè)計(jì)。其中硬件部分具體描述了USB2.0控制器CY7C68013和模數(shù)轉(zhuǎn)換芯片A
2、DS7825P的接口設(shè)計(jì),同時(shí)也給出了各種電源轉(zhuǎn)換的實(shí)現(xiàn)方法。在軟件部分,通過分析EZ-USB的固件編程框架驅(qū)動(dòng)程序是系統(tǒng)硬件和應(yīng)用程序之間通信的橋梁,文中介紹了USB的LABVIEW驅(qū)動(dòng)程序設(shè)計(jì)過程;最后,設(shè)計(jì)了數(shù)據(jù)采集和上位機(jī)驅(qū)動(dòng)的應(yīng)用程序,并對(duì)其功能做了解釋。系統(tǒng)不僅實(shí)現(xiàn)了數(shù)據(jù)的采集、傳輸和保存數(shù)據(jù)的功能,并且具有熱插拔、即插即用、便攜式的特點(diǎn),達(dá)到了預(yù)期的效果。關(guān)鍵詞:離心泵測試,數(shù)據(jù)采集,USB2.0,驅(qū)動(dòng)程序,LabVIEWI河北工程大學(xué)畢業(yè)設(shè)計(jì)AbstractCentrifugalpumpsarewidel
