频率量输出型传感器的动态校准方法研究

STUDY ON DYNAMIC CALIBRATION METHOD FOR TRANSDUCERS WITH FREQUENCY-OUTPUT

研究了频率量输出型传感器的动态校准问题．探讨了满足动态校准要求的非等周期频率测量方法以及相应的测量精度、分辨率和采样周期之间的关系．提出了非等周期时间序列分析的虚拟采样预处理方法，进而实现用常规的分析法来分析频率量输出型传感器的动态性能和建立其动态模型．

Dynamic calibration method for transducers with frequency-output is studed in this paper. A frequency measurement method which may be used in dynamic calibration for this kindof transducers is discussed. And the formula that express the relation among measurementaccuracy, resolution and sampling cycle are given out. A virtual sampling pretreatmentmethod for unequal-cycle time series is proposed, so that it can be analysed with conventionalanalysis methods.
