Full-Phase Wind Speed and Direction Algorithm for Acoustic Resonance Wind Sensor
In this study,an ultrasonic resonance-based method is proposed for solving full phase wind speed and wind direction.An equilateral triangular distribution of three ultrasonic transducers A,B,and C with an interval L is established.The initial phases of echo waves received by ultrasonic transducers A,B,and C are measured based on the obtained initial phases of echo waves.Furthermore,the wind speed and wind direction data under the condi-tions of direct wind blowing from the vertex without angle and wind blowing from the vertex with angle are calculat-ed.Additionally,the full-phase wind speed and wind direction algorithm established in this study is continuous and singularity-free.Under the same input conditions,the proposed method exhibits smaller wind speed fluctuation and more accurate wind direction calculation when compared to other methods.
