| 中文摘要: |
| 介绍了光纤陀螺开环信号的数字评价系统。把锁相放大器提取的陀螺信号输出到计算机,设计出友好的人机界面;用零漂、标度因数等参数来评价光纤陀螺的性能。PC机和SR830分别采用USB和GPIB(general-purposeintefacebus)接口,这样在Windows平台下采用VC++设计的数字采集处理系统就可以实时控制进程、高速收发数据以及用图形和文字可视化显示其结果,使系统的可靠性增加,误码率降低,同时检测系统也实现了标准化。 |

| This paper introduces the evaluation system of open loop signal of fiber optic gyroscope.We give the signal got from gyroscope by Lock_-in Amplifier to PC,design friend interface between human and PC,and evaluate the capability of FOG by bias,bias stability,scale factor and so on.PC and SR830 adopt USB and GPIB interface,thus we can control the real time course by the digital sampling and processing system designed by VC++ on windows,high speed receiving and sending data and display the result by picture and words.Then we increase the stability of system,and reduce the error rate,and the standardization of detection system is realized. |
