A Virtual Instrument Based Testing System for Micro Gyroscope with Magnetically Levitated Rotor

针对悬浮转子微陀螺的静态角度测试和漂移度测试任务,对微陀螺信号拾取电路的输出进行了分析,使用虚拟仪器技术研制了基于LabVIEW的测试软件。使用图形控件实现了实时线性度计算和漂移曲线的计算及绘制。该系统简化了悬浮转子微陀螺的测试过程,减少了人工操作,提高了检测效率,并且可以在测试过程中监测到实时数据,具有直观、准确的特点,成为悬浮转子微陀螺性能测试的高效工具。

For the purpose to detect the static angle response and static drift of the micro gyroscope, the analysis of the signal pick up circuit is implemented. Based on the virtual instrument technology, LabVIEW software are developed to compute the linearity and draw the drift curve.. This test system simplifies the process of the gyro characteristic, decreases the working amount of the test stuff and improves the efficiency of the test. The experiment shows successful results and it became the high efficiency tool for the test of micro gyroscope with magnetically levitated rotor.
