基于USB接口的数据采集模块的设计与实现Design and Implementation of USB-Based Data Acquisition Module路 永 伸(天津科技大学电子信息与自动化学院，天津300222)摘要文中给出基于USB接口的数据采集模块的设计与实现。硬件设计采用以Adpc831与PDIUSBDI2为主的器件进行硬件设计，采用Windriver开发USB驱动，并用Visual C十十6.0对主机软件中硬件接口操作部分进行动态链接库封装。关键词USB 数据采集Adpc831 PDNSBDI2 Windriver动态链接库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. The USB drive is developed场Wmdriver, and the operation on the hardware interface is packaged into Dynamic Link Libraries场Visual C++6.0. Keywords USB DataA cquisition Adttc831 PDfUSBD12 Windriver0 引言US B总 线 是新一代接口总线，最初推出的目的是为了统一取代PC机的各类外设接口，迄今经历了1.0,1.1与2.0版本3个标准。在国内基于USB总线的相关设计与开发也得到了快速的发展，很多设计者从各自的应用领域，用不同方案设计出了相应的装置[1,2]。数据采集是工业控制中一个普遍而重要的环节，因此开发基于USB接口的数据采集模块具有很强的现实应用意义。虽然 US B总线标准已经发展到2.0版本，但由于工业控制现场干扰信号的情况比较复杂，高速数据传输的可靠性不容易被保证，并且很多场合对数据采集的实时性要求并不高，开发2.0标准产品的成本又较1.1标准产品高，所以笔者认为，在工业控制领域，目前开发基于USB总线1.1标准实现的数据采集模块的实用意义大于相应2.0标准模块。

本书由Java技术的创建者编写，对Java 2平台标准版，V1.2中新增加的包及类进行了描述。本书主要由包概述和类描述构成。包概述对每个包及其所有类进行了简要描述，另外还画出了包中的类的继承层次结构示意图。每个类描述都独自构成一个小节，包含了类层次结构示意图、类描述、类示例、成员概述以及那些在版本1.2中作了修改或新增的类成员的描述。还详细说明了Java软件开发包（JDK）1.1到从版本1.2对类及方法所作的修改。需要指出的是：本书是补充版本，有些材料需要参阅《The Java Class Libraries, Second Edition, Volume 1》一书的内容。 本书是参考手册而不是指导手册，它不对Java语言进行解释。为了快速定位所需要的类或类成员的信息，本书按类的字母顺序组织。 本书由赵皑、黄志军、阳亮组织翻译，参加本书翻译的还有姚远、程子进、肖利平、刘永亮、薛亮、毛静萍、查海平、赵峰、郭树厢、曹波、肖斌、彭建明、郑欢。参加录入工作的有陈军、姜明、姜志明、张志荣等。 希望本书能够帮助Java程序员获取完整、专业和权威的信息，同时也希望本书能够帮助读者更全面地了解Java语言。由于水平有限和时间仓促，本书的翻译必定会存在一些纰漏，恳切希望广大读者批评指正。

The Small C compiler translates a subset of the C language into assembly language. It runs under PC/MS-DOS 2.1 and later. Small C is compatible with the Microsoft and Small Mac assemblers. Small C takes full advantage of the ability of these assemblers to generate relocatable object code, to maintain Libraries of relocatable modules, and to link separately compiled program modules. It supports a small memory model with one code and one data/stack segment.

OpenCV means Intel® Open Source Computer Vision Library. It is a collection of C functions and a few C++ classes that implement some popular Image Processing and Computer Vision algorithms. OpenCV has cross-platform middle-to-high level API that consists of a few hundreds (>300) C functions. It does not rely on external Libraries, though it can use some when it is possible. OpenCV is free for both non-commercial and commercial use (see the license for details). OpenCV provides transparent interface to Intel® Integrated Performance Primitives (IPP). That is, it loads automatically IPP Libraries optimized for specific processor at runtime, if they are available. More information about IPP can be retrieved at http://www.intel.com/software/products/ipp/index.htm -------------------------------------------------------------------------------- 本文是opencv的入门教程
