加权数据融合方法在多声道超声波流量计测量中的应用
Application of Weighted Data Fusion Method in Multi-Path Ultrasonic Flowmeter Measurement
摘要
Abstract
In view ofthe problem that the measurement error caused by a transducer can not work normally in the measurement of the flow velocity of the multi-path ultrasonic flowmeter. On the basis of multi-sensor data fusion the-ory and its improvement,a data fusion calculation method suitable for multi-path ultrasonic flowmeter is proposed, meanwhile the improved optimal weighted data fusion method can adaptively calculate the optimal weight coefficient after each measurement. The experimental results show that the flow velocity calculated by this method and the Gauss-Jacobi integral method are basically consistent when the channels of the flowmeter can work normally,When single channel of the flowmeter can not work normally,this method can be used to obtain more stable flow velocity than the Gauss-Jacobi integral method,it can reduce the influence of measurement error to the calculation result.关键词
