摘要
当前数据采集卡接口单一,通用性较差,采样率低。针对高速数据采集系统中对数据实时处理和高速传输的需要,提出一种基于FPGA控制芯片的数据采集卡,从整体设计、信号处理、硬件接口、虚拟示波器软件等几个方面进行分析阐述。该数据采集卡具有USB和PXI数据传输接口,实现多通道数据的采集功能。
This paper puts forward a way of implementation of multi-channel data acquisition card（ DAQ card）using FPGA as control core,USB and PXI as data transmission interfaces and has successfully fabricated this novel DAQ card,enabling the data acquisition on account of the singleness,poor versatility and low sampling rate of interfaces of the current DAQ card and in view of the instantaneity and high-speed transmission of data acquisition system. This realizing of data acquisition system is analyzed from the following several aspects： overall design,signal processing,hardware interface,virtual oscilloscope software,etc.
