摘　　要：PC104+总线具有较多的优点,在嵌人式领域得到了越来越广泛的应用,研发基于PC104+总线的通用双通道高速数据采集系统具有较强的实用价值。为了实现此采集系统,在硬件系统上,采用了PCI9054接口芯片、大容量的FPGA和双口RAM、两片AD6640作双通道数据采集的结构。在软件系统上,采用了底层驱动程序、开发函数库、上层应用软件的结构。经实际测试,该系统能稳定工作,完成双通道数据采集。因此,本文提出的数据采集系统硬软件结构及实现方法具有实用及参考意义。PC104 ＋ bus that has more advantages was widely used in the embedded fields, so the research of dual-channel high-speed data acquisition system based on PC104 ＋ bus has more practical value. This paper introduces the method of designing a acquisition system, in the hardware system aspect, the structure of dual channel data acquisition is composed of PCI9054, large capacity FPGA, dual-port RAM and two AD6640 chips. The software system contains bottom driver, functions library for developing and upper application program. Testing show the whole system works well in dual channel data acquisition mode. So the hardware and software structure and their implementation methods presented in this paper has practical reference value.
