摘要
设计了一套基于CPCI总线,PCI9054桥接芯片和可编程逻辑器件(FPGA)的高速数据采集卡。FPGA作为本地主控芯片,根据工控机经PCI9054转发的采集命令,通过光纤接口实现与雷达接收机的通信。采用高速RAM缓存数据,采集的接收机测试数据的分析结果可在工控机上显示,从而实现了对雷达接收机性能的快速测试。该采集卡具有较强的通用性和可扩展性,详细介绍了高速数据采集卡的组成和工作原理、硬件设计。
To facilitate the testing of radar signal receiving system,a high-speed data acquisition card based on CPCI bus,PCI9054 bridge chip and programmable logic device（FPGA） was designed.Taking FPGA as a local master,and according to the acquisition command transmitted by the PCI9054 from computer,it can communicate with radar receiver through optical interface.SRAM is used to cache high-speed data,the analysis results of test data can be displayed on the industrial computer,and then the quick test of the radar receiver is implemented.The capture card has a strong versatility and scalability,the composition,working principle and hardware design of high-speed data acquisition card are described.
