一种高速数据采集卡的设计与实现

为了实现对武器系统模拟信号的采集和数据分析，根据PC／104总线的数据采集系统的设计思想，数据采集卡以A／D转换器、CPLD和FIFO相结合来实现信号的连续采集与数据传输的控制。A／D转换器实现信号的采样保持和模数转换，CPLD实现数据采集和存储过程的控制。实验结果表明，该数据采集卡操作简单、实时性强、性能稳定，可实现对被测信号高速连续的数据采集。

Design and Realization of High-speed Data Acquisition Card

For the purpose of sampling the signal of weapon system and analyzing the data,based on the design method of the data acquisition of PC/104 bus,the data sampling card adopted the combine of A/D Convertor,CPLD and FIFO to achieve the signal continuous sampling and the data transfers controlling.The A/D Convertor achieved the sampling-holding and the analog to digital convertion,and CPLD achieved the control of data sampling and storage process.The result of experiments show that this data sampling card is ea...
