摘要
本文研究了用于涡街流量计信号处理的自适应频率测量方法(AMF),这种方法将自适应滤波和功率谱分析结合在一起,特别适合于测量或估计涡街流量计这类受随机噪声和干扰影响了的信号频率,理论分析和实验结果证明,此法对提高涡街流量计应用中的测量精度是有效的,同时,也适用于其他仪表测量系统。
This paper studies a new Adaptive Measurement of Frequency method (AMF)for vortex flowmeter signal processing. It combines the adaptive filtering with power spectrum analysis. This method is especially suitable for measuring or estimating the frequency of signal such as vortex flowmeter signal with disturbance. Theoretical analysis and experimental results have proved that this method is efficient for improving the measuring accuracy of vortex flowmeter and can also be used in other measuring and instrumentation systems.
