基于FPGA和USB的数据采集系统的设计

Design of data acquisition system based on FPGA and USB

介绍了一种用于炮口冲击波精确测量的数据采集系统设计。该系统是一种基于通用串行总线(USB)接口和FPGA技术的多通道同步数据采集系统,采用FPGA控制系统的采集时序,USB芯片作为数据采集通道,上位机完成数据显示功能,最后对电路进行了环境测试,并分析了测试结果。

This paper introduced the data acquisition system using in the precision measurement of the muzzle blast.The acquisition system based on universal serial bus（USB） and Field Programmable Gate Array（FPGA）.FPGA control the whole system of collecting time-series,USB chip act as a data acquisition channel,and PC completes data display.Finally,environment testing for the system is carried on,and the comparison and analyses are made in terms of experiment results.
