1、西北工業(yè)大學(xué)碩士學(xué)位論文摘要電動轉(zhuǎn)轍機(jī)是鐵路系統(tǒng)中常用的一種重要電氣信號設(shè)備。它是以電動機(jī)為動力，經(jīng)減速器變速后來改變道岔的開通方向，并能夠反映道岔的狀態(tài)位置。便攜式電動轉(zhuǎn)轍機(jī)測試儀是一種專門用來在現(xiàn)場對電動轉(zhuǎn)轍機(jī)進(jìn)行檢測的測試設(shè)備，其測量對象為電動轉(zhuǎn)轍機(jī)動作過程中的輸出力和電機(jī)電流。本論文首先對基于ARM的便攜式電動轉(zhuǎn)轍機(jī)測試儀的各種設(shè)計要求進(jìn)行了分析，包括了儀器的精度以及各種使用功能要求。然后提出了測試儀的總體設(shè)計方案：從邏輯上將儀器劃分為三個層次：硬件電路層、接口層和軟件應(yīng)用層，依次實現(xiàn)儀器硬件電路的設(shè)計、驅(qū)動程序的設(shè)計和功能軟
2、件的設(shè)計。在本論文的設(shè)計中，儀器采用了“定時器中斷”來保證對被參數(shù)進(jìn)行實時、有效地測量：使用了PC／GUI來編寫友好的圖形用戶界面；用軟件實現(xiàn)了文字信息一一包括數(shù)字、字母和漢字的輸入；并在儀器上構(gòu)建了FAT文件系統(tǒng)，使其可以像u盤一樣方便地通過USB接口與Pc機(jī)之間進(jìn)行數(shù)據(jù)通信。經(jīng)過驗證測試證明，所設(shè)計測試儀的測量精度達(dá)到技術(shù)指標(biāo)的規(guī)定；能夠?qū)崟r地完成對被測參數(shù)的測量，測量波形不失真；并且滿足了設(shè)計要求中所提出的各項操作功能。關(guān)鍵詞：轉(zhuǎn)轍機(jī)，定時中斷，uC／GUI，USB，F(xiàn)AT文件系統(tǒng)西北工業(yè)大學(xué)碗上學(xué)位論文AbstractThee
