信号的采集是当今社会非常重要的一方面，是信号分析的基础，其 NI 公司采集卡在 FPGA 模式下采集到的数据是通过数据包的形式进行传输，文件大小依靠 FIFO 读取函数元素数量控制，但仅靠单个 FIFO 最多传输8路数据，否则会造成数据丢失的问题，基于此利用双 FIFO 双队列的方式传输16路数据，并利用分文件二进制存储的方式满足了快速存储与文件打开受行数与列数限制的问题。经验证，工作稳定，满足工程要求，并实现了采集卡变速率的采集。

Signal acquisition,a very important aspect of today's society,forms the basis of signal analysis.The data collected by NI through its acquisition card in FPGA mode are transmitted through data package,and the file size depends on the number of functional elements read by FIFO.However,a single FIFO can only transmit 8 channels of data,otherwise,data might be lost.Based on the dual FIFO dual queue transmission,a total of 16 channels of data can be transmitted,and the binary storage of sub -files meets the requirement on fast storage and solves the problem that file opening is constrained by the number of rows and the number of columns.Verification shows that the scheme works steadily,meets engineering requirements,and realizes collection at variable rate via the acquisition card.
