基于Zynq的大动态冲击波超压测试系统设计

Design of a large dynamic shock wave overpressure test system based on Zynq

针对实战演练过程中,冲击波超压大动态获取的需求,开展了基于Zynq的多通道多量程复合式冲击波超压采集存储系统设计。首先,以Zynq-7000系列SOC为核心,设计了传感器调理电路,四通道20 MHz采样率采集系统,基于D-LMS的实时自适应降噪模块和DMA高速存储模块;其次对AD采集、片上自适应滤波等模块进行了仿真验证;最后在外场进行了试验验证,结果表明设计的大动态冲击波超压测试系统,能有效获取冲击波超压信号,该成果能够为大威力新型压制型武器的动态毁伤评估提供理论支撑。

In view of the need of dynamic acquisition of shock wave overpressure during the actual combat drill,the design of multi-channel multi-range composite shock wave overpressure acquisition and storage system based on Zynq is carried out.First of all,with Zynq-7000 series SOC as the core,the sensor conditioning circuit,the four-channel 20 MHz sample rate acquisition system,the D-LMS-based real-time adaptive noise reduction module and DMA high-speed storage module are designed;The results can provide theoretical support for the dynamic damage assessment of powerful new repressive weapons.
