基于USB接口的數(shù)據(jù)采集模塊的設(shè)計(jì)與實(shí)現(xiàn)Design and Implementation of USB-Based Data Acquisition Module路 永 伸(天津科技大學(xué)電子信息與自動化學(xué)院,天津300222)摘要文中給出基于USB接口的數(shù)據(jù)采集模塊的設(shè)計(jì)與實(shí)現(xiàn)。硬件設(shè)計(jì)采用以Adpc831與PDIUSBDI2為主的器件進(jìn)行硬件設(shè)計(jì),采用Windriver開發(fā)USB驅(qū)動,并用Visual C十十6.0對主機(jī)軟件中硬件接口操作部分進(jìn)行動態(tài)鏈接庫封裝。關(guān)鍵詞USB 數(shù)據(jù)采集Adpc831 PDNSBDI2 Windriver動態(tài)鏈接庫Abstract T hed esigna ndim plementaitono fU SB-BasedD ataA cquisiitonM oduleis g iven.Th ec hips oluitonm ainlyw ithA dpc831a ndP DTUSBD12i sused for hardware design.

Keywords USB DataA cquisition Adttc831 PDfUSBD12 Windriver0 引言US B總 線 是新一代接口總線,最初推出的目的是為了統(tǒng)一取代PC機(jī)的各類外設(shè)接口,迄今經(jīng)歷了1.0,1.1與2.0版本3個標(biāo)準(zhǔn)。在國內(nèi)基于USB總線的相關(guān)設(shè)計(jì)與開發(fā)也得到了快速的發(fā)展,很多設(shè)計(jì)者從各自的應(yīng)用領(lǐng)域,用不同方案設(shè)計(jì)出了相應(yīng)的裝置[1,2]。數(shù)據(jù)采集是工業(yè)控制中一個普遍而重要的環(huán)節(jié),因此開發(fā)基于USB接口的數(shù)據(jù)采集模塊具有很強(qiáng)的現(xiàn)實(shí)應(yīng)用意義。雖然 US B總線標(biāo)準(zhǔn)已經(jīng)發(fā)展到2.0版本,但由于工業(yè)控制現(xiàn)場干擾信號的情況比較復(fù)雜,高速數(shù)據(jù)傳輸?shù)目煽啃圆蝗菀妆槐WC,并且很多場合對數(shù)據(jù)采集的實(shí)時性要求并不高,開發(fā)2.0標(biāo)準(zhǔn)產(chǎn)品的成本又較1.1標(biāo)準(zhǔn)產(chǎn)品高,所以筆者認(rèn)為,在工業(yè)控制領(lǐng)域,目前開發(fā)基于USB總線1.1標(biāo)準(zhǔn)實(shí)現(xiàn)的數(shù)據(jù)采集模塊的實(shí)用意義大于相應(yīng)2.0標(biāo)準(zhǔn)模塊。

The PL2303 USB to Serial adapter is your smart and convenient accessory forconnecting RS-232 serial devices to your USB-equipped Windows host computer. Itprovides a bridge connection with a standard DB 9-pin male serial port connector inone end and a standard Type-A USB plug connector on the other end. You simplyattach the serial device onto the serial port of the cable and plug the USB connectorinto your PC USB port. It allows a simple and easy way of adding serial connectionsto your PC without having to go thru inserting a serial card and traditional portconfiguration.This USB to Serial adapter is ideal for connecting modems, cellular phones, PDAs,digital cameras, card readers and other serial devices to your computer. It providesserial connections up to 1Mbps of data transfer rate. And since USB does not requireany IRQ resource, more devices can be attached to the system without the previoushassles of device and resource conflicts.Finally, the PL-2303 USB to Serial adapter is a fully USB Specification compliantdevice and therefore supports advanced power management such as suspend andresume operations as well as remote wakeup. The PL-2303 USB Serial cable adapteris designed to work on all Windows operating systems.

本文探討如何透過USB來設(shè)定各種采用FPGA的系統(tǒng)與實(shí)現(xiàn)現(xiàn)場升級的彈性。這種方法還可用來取代熱門的JTAG組態(tài)介面,讓用戶不再需要用到機(jī)板上分立的JTAG連結(jié)器,就能降低成本并減少占用電路板的空間。
