基于极性相关算法的流速测量系统研究
Flow Velocity Measurement System Based on Polarity Correlation Algorithm
摘要
Abstract
Flow velocity measurement,as an important part of flood warning,is significant,but the ac-curacy of conventional instrument is poor,therefore,a polarity correlation algorithm is present for flow velocity measurement.This paper summarizes the basic principle of correlation method in the flow veloc-ity measurement,and then advances an improved algorithm of polarity correlation method.Then the al-gorithm analysis and circuit implementation are carried out.The simulation experiments based on the Monte Carlo method show that the polarity correlation algorithm can replace common correlation algo-rithms on peak point determination.It has good anti-interference function due to the particularity of the algorithm.The comparison of experimental measurement speed with the speed setting by the Monte Carlo method shows that if the two sampling sensor spacing meet certain conditions,the measurement speed and its fitted curve could have a better Goodness of Fit,and the measurement speed can accurately response the speed set by the Monte Carlo method.Which can validate the feasibility of the algorithm and have an accurate measurement on flow velocity.关键词
