基于PXI总线数据采集系统的设计

Design of data acquisition system based on PXI bus

本文介绍一种通用的数据采集系统来对压力,温度等进行数据采集和处理。文中包含了采集系统的硬件设计和软件设计两部分,其中硬件部分包括PXI采集板卡,软件部分包括采集板卡WDM驱动,基于C#的上位机界面以及与MATLAB的混合编程。实际应用表明,该系统具有操作简便、测试准确的特点,达到了设计要求。

In order to collect and deal with the data,such as pressure and temperature, a general-purpose data acquisition system is designed in this paper. It contains the hardware system and the software system. The hardware part introduces the design of the PXI Card. what＇s more, the software part introduces the Card WDM driver, the mixed programming of MATLAB and C#. The experiment and application show that this test system has good performance, and achieve the design requirement.
