摘要
船用动调陀螺仪捷联惯性系统中 ,需要对陀螺仪力反馈回路中的宽动态范围电流信号进行精确、实时测量。本文详细介绍了一种采用串行ADC线路的大动态范围高速数据采集系统 ,其动态范围优于 138dB ,采样频率可达 75kS/s。
In strapdown inertial system for vessels with Dynamically Tuned Gyroscope (DTG),current signal of wide dynamic range in force feedback loop of DTG must be measured with high accuracy and real-time performance.Application of ADC with serial interface on data acquisition system with 138dB dynamic range and 75kS/s sample frequency can fulfill the signal acquisition of DTG very well.
