【摘要】 本论文主要研究利用PCI总线技术在数据采集领域的实现与应用的问题。随着信息技术(IT)特别是计算机技术的迅猛发展，工农业生产、医疗和科研等领域对数据收集与处理提出了更高的要求，我国利用高速的PCI总线技术在这一领域的应用却相对落后，本课题就是出于这一目的而提出来的。本课题包括硬件电路、印刷电路板(PCB)、驱动程序和应用软件的设计，涉及A/D板和D/A板两大块部分，具体的功能模块包括多路信号选择模块、模数转换模块、数模转换模块、PCI协议转换模块、驱动放大模块、控制逻辑、时钟电路和配置电路，其中重点是A/D板部分。课题着重点是最新的PCI总线规范2.2在数据采集系统领域的应用和驱动程序的开发，利用PLX公司2000年才刚刚研发并生产的PCI协议芯片PCI9030。硬件电路的绘制采用PROTEL 99电路软件，而驱动程序则采用WinDriver5.3开发工具，应用软件则利用VISUAL C++ 6.0高级编程软件。本课题已基本完成硬件电路调试、驱动程序开发与安装等工作，获得用户好评。本论文主要阐述了数据采集的意义和任务、当今利用PCI总线技术运用于数据采集系统的最新动态、数据采集的基本理论、PCI规范的重要内容、PCI数据采集系统的硬件电路设计、驱动程序的设计、应用软件的开发和整个系统的应用等方面的内容更多还原

【Abstract】 This paper mainly studied the realization and application of data acquisition system using the PCI bus.With the rapid development of information technology (IT), especial computer technology, industry and agriculture manufacture, medical and scientific research bring forward higher request for data gathering and processing. China relatively drops behind other developed countries in making use of high speed PCI Bus technology. The thesis is put forward in order to settle the question.The thesis includes the design of hard circuit, PCB(Printed Circuit Board), Driver and application soft involving A/D board and D/A board. The detailed functional modules consist of multiplex signals select module、analog digital conversion module、digital analog conversion module、PCI protocol conversion module、driver and magnifying module、control logic、clock circuit and configuration circuit. The importance of the thesis is A/D board. The thesis emphasizes the application of newly PCI Bus specification 2.2 in data acquisition system and the development of driver using the PCI9030 chip which is just studied and produced in PLX Company in 2000. The hard circuit is drawn employing circuit soft Protel99. The driver is developed using developing tool WinDriver5.3 and the application soft is programmed making use of advanced programming soft Visual C++ 6.0. This thesis basically has been completed hard circuit debug、driver develop and installation，has been received good customers’ comments. This paper mainly states the meaning and task of data acquisition、newly trends of data acquisition system using today PCI Bus technology、foundation theory of data acquisition、 most contents of PCI 2.2 specification、hard circuit design of PCI data acquisition system、design of driver、development of application soft and application of the whole system更多还原
