1、華北電力大學(xué)碩士學(xué)位論文摘要隨著振動監(jiān)測與故障診斷技術(shù)的應(yīng)用與普及，對振動測試分析儀器的性能要求也在不斷提高。為了提升現(xiàn)今便攜式振動分析儀器的性能和功能，本文運用嵌入式系統(tǒng)技術(shù)，開發(fā)了基于ARM技術(shù)的新型手持式雙通道振動采集與轉(zhuǎn)速測量系統(tǒng)。儀器采用基于ARMg技術(shù)的53C2440為CPU和具有24位轉(zhuǎn)換精度的模數(shù)轉(zhuǎn)換器ADS1274，配置了高分辨率TFT彩色液晶觸摸顯示屏LS037V7DW01，鍵盤，并利用SD卡進(jìn)行擴(kuò)展存儲，通過USB把數(shù)據(jù)傳入PC機(jī)。針對系統(tǒng)硬件開發(fā)了基于WindowsCES.0嵌入式操作系統(tǒng)的硬件驅(qū)動程序。采用FIQ中斷方法解決中斷響應(yīng)速度不及時的
