摘要
以PXI总线为基础,介绍了符合PXI总线标准的多功能专用板卡。PXI多功能专用板卡主要完成多种信号的输入、输出与控制功能,包括A/D转换、D/A转换和I/O开关量等功能模块电路,能有效对各功能模块进行闭环控制,完全能够满足系统中对多种信号输入输出和各种处理的要求。将此板卡应用于车用仪表性能检测系统中,与CCD图像采集和DSP处理系统结合,具有检测实时性好、精度高、通用性强、功能全面、性价比高、操作简便等优点。
This article is based on a PXI bus,PXI bus,introduced in line with the standards dedicated multi-function board.PXI multifunction board dedicated primarily to complete a variety of signal input,output and control functions,including A/D converter,D/A converters and I/O function modules such as switch circuit,can effectively function on the closed-loop control module,fully able to meet a wide range of systems and a variety of input and output signal processing requirements.Used in vehicle performance testing instrument systems and combined with CCD image acquisition and DSP processing system,it has the advantages of good real-time detection,high precision,high universality,full-featured,cost-effective,easy to operate and so on.
