  • 基于ARM的數(shù)據(jù)采集卡研制

    根據(jù)機械電子工程類專業(yè)測控實驗教學(xué)平臺數(shù)據(jù)采集的需要,在綜合考慮成本和性能基礎(chǔ)上,提出以為主處理芯片的數(shù)據(jù)采集卡設(shè)計方案。 該方案的主要特點是,使用基于ARM7TDMI內(nèi)核的,工作主頻最高可達(dá)44MHz;內(nèi)置高性能的ADC和DAC模塊,采樣速度最高可達(dá)1MSPS,采樣精度為12位;模擬信號輸入通道最多可達(dá)16路,模擬信號輸出通道最高可達(dá)4路;具有豐富的外設(shè)資源可以使用,GPIO口數(shù)目最高可達(dá)40個。 在設(shè)計中采用了模塊化思想,將系統(tǒng)分為四個功能模塊:主模塊的功能是控制ADC進(jìn)行信號采集和DAC進(jìn)行模擬信號輸出;模擬信號模塊的作用是對傳感器輸入信號和DAC輸出波形進(jìn)行簡單的調(diào)理;數(shù)字信號模塊引出32路數(shù)字I/O口,可用于需要采集數(shù)字量的場合;JTAG模塊可進(jìn)行程序的調(diào)試和下載,對于數(shù)據(jù)采集卡的二次開發(fā)有很大的作用。 在本數(shù)據(jù)采集卡上,嘗試進(jìn)行了μC/OSⅡ操作系統(tǒng)的移植,成功實現(xiàn)了四個任務(wù)的管理。在實際應(yīng)用中,工作數(shù)小時仍可保持正常的運行。 為檢驗數(shù)據(jù)采集卡的串口通訊能力,利用LabVIEW程序讀取下位機串口發(fā)送的已采集到的數(shù)據(jù),進(jìn)行波形圖繪制。 為檢驗本數(shù)據(jù)采集卡的ADC和DAC精度,設(shè)計實驗利用DAC輸出波形,并利用ADC將采集到的波形通過LabVIEW顯示,測量結(jié)果顯示兩者電壓值誤差均在可允許的3LSB(Least Significant Bit)范圍內(nèi),表明本數(shù)據(jù)采集卡已基本實現(xiàn)預(yù)期設(shè)計指標(biāo)。

    高速數(shù)字系統(tǒng)設(shè)計下載pdf:High-Speed Digital SystemDesign—A Handbook ofInterconnect Theory and DesignPracticesStephen H. HallGarrett W. HallJames A. McCallA Wiley-Interscience Publication JOHN WILEY & SONS, INC.New York • Chichester • Weinheim • Brisbane • Singapore • TorontoCopyright © 2000 by John Wiley & Sons, Inc.speeddigital systems at the platform level. The book walks the reader through everyrequired concept, from basic transmission line theory to digital timing analysis, high-speedmeasurement techniques, as well as many other topics. In doing so, a unique balancebetween theory and practical applications is achieved that will allow the reader not only tounderstand the nature of the problem, but also provide practical guidance to the solution.The level of theoretical understanding is such that the reader will be equipped to see beyondthe immediate practical application and solve problems not contained within these pages.Much of the information in this book has not been needed in past digital designs but isabsolutely necessary today. Most of the information covered here is not covered in standardcollege curricula, at least not in its focus on digital design, which is arguably one of the mostsignificant industries in electrical engineering.The focus of this book is on the design of robust high-volume, high-speed digital productssuch as computer systems, with particular attention paid to computer busses. However, thetheory presented is applicable to any high-speed digital system. All of the techniquescovered in this book have been applied in industry to actual digital products that have beensuccessfully produced and sold in high volume.Practicing engineers and graduate and undergraduate students who have completed basicelectromagnetic or microwave design classes are equipped to fully comprehend the theorypresented in this book. At a practical level, however, basic circuit theory is all thebackground required to apply the formulas in this book.

  • 簡述PCB線寬和電流關(guān)系

      PCB線寬和電流關(guān)系公式   先計算Track的截面積,大部分PCB的銅箔厚度為35um(即 1oz)它乘上線寬就是截面積,注意換算成平方毫米。 有一個電流密度經(jīng)驗值,為15~25安培/平方毫米。把它稱上截面積就得到通流容量。   I=KT(0.44)A(0.75), 括號里面是指數(shù),   K為修正系數(shù),一般覆銅線在內(nèi)層時取0.024,在外層時取0.048   T為最大溫升,單位為攝氏度(銅的熔點是1060℃)   A為覆銅截面積,單位為square mil.   I為容許的最大電流,單位為安培。   一般 10mil=0.010inch=0.254mm 1A , 250mil=6.35mm 8.3A ?倍數(shù)關(guān)系,與公式不符 ?

  • 使用5V電源的高分辨率視頻解決方案

      Video cable driver amplifi er output stages traditionallyrequire a supply voltage of at least 6V in order to providethe required output swing. This requirement is usuallymet with 5V supplies by adding a boost regulator or asmall local negative rail, say via the popular LT®1983-3.Such additional circuitry is unnecessary in typical 1VP-Pvideo connections, such as HD component video, if thecable driver amplifi ers simply offer near rail-to-rail outputcapability when powered from 5V.

  • 利用高壓看門狗定時器加強汽車安全系統(tǒng)

      Abstract: As electronic systems take over many of the mechanical functions in a car—ranging from engine timing to steering andbraking—there is a growing concern about fault tolerance. There should not be a single point of failure that would prevent a car fromat least "limping" off the road or making it to the nearest service station. Redundant systems, watchdog timers, and other controlcircuits are used to reroute signals and perform other functions that ensure that a vehicle can safely make it off the road when afailure occurs.
