摘要
为了解决地震物理模拟采集中采样率和分辨率的瓶颈问题,引用并行高速采样方案,在保证高采样率的同时,提高采样分辨率。利用两块NI PXI5922高速采集卡、一台超声发射仪、一对超声换能器和前置放大器,完成了并行高速采样在地震物理模拟采集的应用设计。
In order to solve the bottleneck problems in geophysical modeling acquisition—sampling rate and resolution,this paper uses parallel high-speed sampling scheme to ensure high sampling rate and improve the sampling resolution. It uses two pieces high-speed data acquisition card NI PXI5922,an ultrasonic transmitting apparatus,a pair of ultrasonic transducer and a preamplifier to complete the parallel high-speed sampling in the application of geophysical modeling acquisition design.
