The PLX9054 interface chip is introduced, then the design of collection system based on PCI bus is presented, and the method of designing driver program in Windows operation system is described. This system utilizes analog-to-digital converter and PCI bus to transfer high speed digital signals, which can implement in current computer using interruption and DMA mode.%在介绍使用PLX9054接口芯片的基础上,给出了一种基于PCI总线的数据采集系统的方案设计,及在Windows操作系统下开发底层驱动程序的方法.该系统使用模数转换器件和PCI总线传输高速数字信号,工作在通用计算机上,同时支持中断和DMA方式实现高速数据传输.
