基于DSP和FPGA的导引头数据采集系统设计

为适应导引头多路数据采集的要求,本文设计了一种基于DSP和FPGA的多通道导引头数据采集系统;在介绍系统总体方案的基础上,详细讨论了数据采集部分的模拟通道、A/D变换、数字滤波,DSP与FPGA操作时序、上位机通信接口等电路设计和实现,并介绍了软件设计和软面板,最后给出测试结果和分析。本系统已成功的应用于某型号导弹自动测试系统中,其性能和指标均优于应用要求。

Design of seeker data acquisition system based on DSP and FPGA

For multi-channel on seeker data acquisition,a seeker data acquisition system based on DSP and FPGA is designed in this paper.The principle of the data acquisition system is introduced.Four parts are expounded in details such as analog channel,A/D converter,digital filter,operation time of DSP and FPGA.At last,the design of software and softpanel is presented.The seeker data acquisition has been made and used in actual automatic measurement system.It is indicated through experiment that this system has good performance and is better than application request.
