【摘要】 基于PCI总线的高速数据采集系统是近年来数据采集、传输技术的一个发展方向。由于PCI总线具有的一系列优点，在许多领域的应用中PCI总线正在成为事实上的标准。本文以基于PCI的高速数据采集系统中的某些关键技术为研究对象，做了以下几方面的工作。 提出了由高速高精度A/D转换芯片、高性能DSP芯片、PCI总线接口组成和由高速高精度A/D转换芯片、MCU、双口RAM、PCI总线接口组成的两种系统方案。比较了这两种方案的优缺点，并且根据教研室的实际情况确定了以ADuC812、双口RAM、PCI9052构成的数据采集系统方案。列举了目前比较流行的几种PCI接口方法，并确定PCI9052为系统的PCI接口芯片。 同时，本文详细地介绍了包括ADuC812、双口RAM、CPLD、PCI9052的数据采集系统软硬件的具体实现。硬件方面具体叙述了系统各个模块的功能、实现方法和相互连接方式。软件方面重点介绍了驱动程序开发的过程和要点，并且详细叙述了利用PLX公司的SDK工具包开发应用软件。更多还原

【Abstract】 In recent years, based on PCI bus high-speed data collecting system is a developing direction of data gather and transmission technology. Because of PCI bus has a series of merits, application in a lot of fields PCI bus is becoming the standard in fact. This text regarded some key technology in the data collecting system at a high speed based on PCI as the research object, and has done the work of the following aspects.I have proposed two kinds of systematic schemes of interface: one is composed of a high-speed and high-accuracy A/D transition chip, a High-performance DSP chip and the PCI bus interface; the other is composed of a high speed and high-accuracy A/D transition chip, a MCU, a dual port RAM and the PCI bus interface. I have compared the advantages and disadvantages of these two kinds of schemes, and have confirmed with the data collecting system scheme including an ADuC812, a dual port RAM and the PCI9052 according to the actual conditions of the teaching and research room. I enumerated several popular PCI interface method at present and chose the PCI9052 as interface chip of system.This text has recommended the concrete actualized of the software and the hardware composed of an ADuC812, a dual port RAM, the CPLD and the PCI9052 data collecting system in detail. Hardware has narrated concretely system each function, implementation method and joining each other of module. Software has given course and main point of procedure making driver especially, and utilized SDK tool of PLX Company make application software of developing in detail.更多还原
