摘要：

为实现激光-水声浅海地形遥感探测中,激光多普勒测振计的数据采集和处理,解决数据采集处理中采样率低、人机界面操作不便、在线处理不及时、采样通道数目少等问题,设计了一种可视化的信号采集和处理系统。借助VC+[KG-1.5mm]+编程技术,对PCI5616数据采集卡进行了二次开发,实现了激光多普勒测振计输出信号的采集、实时显示、保存以及在线处理。实验表明,该信号采集处理系统能满足实际水面测量的工作需求,有效实现了激光多普勒测振计输出信号的实时采集与处理,并具有操作灵活、实时性强、集成度高等特点。

Abstract:

A visual data acquisition and processing system is presented to satisfy the signal processing specification of the laser Doppler vibrometer (LDV) working for the optic-acoustic remote sensing of the shallow terrain and to resolve the questions of low sampling rate,inconvenient man-machine interface and the less number of channels for sampling.VC+[KG-1.5mm]+ is employed in the post-development of PCI5616 to achieve real-time display,acquisition,storage,and real-time data-processing of the signals.With good processing capacity,flexible operation,good real-time performance and high integration,this data acquisition and processing system realizes the real-time acquisition and processing of the output signals of LDV and meets the demand of topographic mapping under the hydrodynamic water surface.

Key words: laser Doppler vibrometer;data acquisition;real time process;PCI5616;messages mechanism
