光纤陀螺捷联系统数据采集方案研究

Research on the method of data sampling on accelerometer in strap down system based on fiber optic gyro

根据光纤陀螺捷联系统的要求,提出了基于高分辨率模数转换器和数字信号处理器的加速度计数据采集方案.同时根据捷联系统3个通道输出速度的要求,设计了并行采集方案,并对于高分辨率模数转换器的选择作了讨论计算.

According to the need of trap down system based on fiber optic gyro, a method of data sampling on accelerometer based on high resolution analog-digital converter was brought out. At the same time, according to the output speed of the three channels in trap down system, a parallel sampling plan was designed . Then it was also discussed and calculated on how to select the high resolution analog-digital converter.
