1、浙江工業(yè)大學(xué)碩士學(xué)位論文基于USB總線的數(shù)據(jù)采集系統(tǒng)的設(shè)計(jì)與實(shí)現(xiàn)姓名:鄭青申請學(xué)位級別:碩士專業(yè):機(jī)械電子工程指導(dǎo)教師:姜偉20070401基于USB總線的數(shù)據(jù)采集系統(tǒng)的設(shè)計(jì)與實(shí)現(xiàn)摘要本課題主要針對USB接口的數(shù)據(jù)采集系統(tǒng)的設(shè)計(jì)。該數(shù)據(jù)采集系統(tǒng)充分發(fā)揮了USB成本低、熱插拔、支持高、中、低速范圍的數(shù)據(jù)傳輸?shù)葍?yōu)點(diǎn),滿足了目前對數(shù)據(jù)采集系統(tǒng)不斷提高的要求。本文根據(jù)設(shè)計(jì)需要,分析了USBI.1協(xié)議,對USB通信原理、USB系統(tǒng)體系、數(shù)據(jù)包格式、USB標(biāo)準(zhǔn)描述符進(jìn)行了深入研究,并在此基礎(chǔ)上提出了USB數(shù)據(jù)采集系統(tǒng)的總體框架設(shè)計(jì)。依據(jù)總體框架設(shè)計(jì)數(shù)據(jù)采集系統(tǒng)由兩部分組成:
2、硬件設(shè)計(jì)和軟件設(shè)計(jì)。硬件設(shè)計(jì)主要由兩個(gè)功能模塊構(gòu)成:母板模塊,業(yè)務(wù)板模塊。其中母板模塊主要實(shí)現(xiàn)主控制器與PC的通信問題,以TMS470RlA256(ARM7TDMI)為主控制器;業(yè)務(wù)板模塊主要實(shí)現(xiàn)數(shù)據(jù)采樣,i/o擴(kuò)展等電路設(shè)計(jì)。軟件設(shè)計(jì)主要分為三部分:一是滿足系統(tǒng)運(yùn)行效率和功能要求的固件程序設(shè)計(jì);二是提供動(dòng)態(tài)鏈接庫接口功能函數(shù)、演示和測試功能的用戶服務(wù)程序和工程應(yīng)用實(shí)例;三是介紹了設(shè)備驅(qū)動(dòng)程序的開發(fā)。在論文結(jié)尾,結(jié)合在系統(tǒng)開發(fā)過程遇到的一些實(shí)際情況,為今后研究提出了一些建議,并對USB的應(yīng)用前景進(jìn)行了展望與總結(jié)。本系統(tǒng)的實(shí)現(xiàn)方案和理論分析為后續(xù)研究和開發(fā)打下了基
