摘要:

简述了数字滤波器和互相关滤波两种涡街流量计数字信号处理的设计方法,利用VB.NET编制了相应滤波算法的程序,并作了性能分析和比较。结果表明,将二次互相关滤波算法引入涡街信号的数字滤波过程中,改善了涡街流量计测量下限受限的情况。

Abstract:

Two methods applied in digital signal processing for vortex flowmeter signal are introduced,which are FIR,IIR digital filtering,correlation filtering.And then these filtering algorithms are implemented by Visual Basic.NET.Finally their performances are analyzed and compared.The results indicate that the introduction of the second cross-correlation filtering algorithm vortex signal digital filtering process,the lower limit of vortex flowmeter measurement of limited problems can be improved.
