一种捷联式水下载体运动参数测试系统

摘要

为研究某载体在水下布放过程中的运动状态,针对其运动的特点,从系统的算法原理到器件选型,设计了一套基于FPGA的捷联式水下运动参数测试系统.该系统可实现对载体的姿态角、航向角、入水深度以及加速度等参数的采集和存储,再使用上位机软件LabVIEW,Matlab等对数据进行处理,可以得到载体的运动参数.通过标定试验和实物模拟试验,验证了本测试系统能够达到产品水下运动参数测试的要求.%As a carrier of the motion state in the water,according to the characteristics of the movement,from the principle of the algorithm to the device selection,a set of motion parameters Strapdown test system based on FPGA is designed.It can realize the course of carrier's attitude angle,angle,depth and degree of the acquisition and acceleration and storage the parameters,and then use the PC software Labview,Matlab to process data.And the motion parameters of the carrier are obtained.Through calibration experiments and physical simulation experiments,it is verified that the test system can meet the requirements of underwater motion parameters testing.
