基于FIFO的VXI总线并行A/D连续采集研究

Research on Continuous Data Acquisition of VXI Parallel A/D Based on FIFO

在许多测试领域中需要连续长时间的信号采集,实现实时监控信号及事后信号回放和分析。VXI总线仪器系统是现代自动测试系统的主流。本文给出了一种在VXI总线并行A/D采集模块上结合FIFO来实现大量数据长时间连续采集的方法。该方法已在某装备测控系统中得到成功应用,取得了较好的效果。

In many testing and controlling fields, a long time and continuous data acquisition is in great need to realize real-time monitoring, playback and analysis after signal gathering. VXI bus Instrument system is the mainstream of modem auto-testing system. A method combined with FIFO to realize large and long-time continuous data acquisition present in this paper based on VXI Bus. This method has already got application in some testing and controlling equipment system, and owned a good result.
