Measurement Performance of Three-Cup Wind Speed Sensor in Non-Horizontal Wind Field

To address the measurement data errors caused by environmental differences between the three cup wind speed sensor under metrological verification conditions and observation scenarios, we commit to studying the authenticity, accuracy, and consistency of air flow rate measurement standards in the process of value transmission. We provide ideas and reference indicators for the evaluation of new product types of the new generation three cup wind speed sensor as a measuring instrument. According to the measurement method of the cup anemometer and the verification regulation of the wind speed and direction sensor of the Automatic Weather Station, and adding the automatic turntable system composed of the angle encoder as the main body in the experiment, we design the experiment of measuring the performance level of the three cup wind speed sensor in the non horizontal wind field. By adjusting the tilt angle of the three cup wind speed sensor in the wind tunnel test section, simulating its measurement state in the natural non horizontal wind field, we synchronously collect the standard indicated wind speed of the wind tunnel, the measured wind speed of the three cup wind speed sensor, and their corresponding tilt angle, calculate the error of the displayed values, and use statistical methods such as variance analysis, trend analysis, correlation analysis, and linear regression analysis, to study the indication error of the three cup wind speed sensor under different tilt angles, and obtain the corresponding relationship between the indication error of the three cup wind speed sensor in the wind tunnel test section and the measured wind speed and tilt angle. We also study the differences in the influence of the rising and falling movements of the near ground air on the display value of the three cup wind speed sensor. We propose the measurement performance indicators of the three cup wind speed sensor in non horizontal wind fields, establish a connection between the experimental data of the standard measurement laboratory and the observation data of the meteorological ground station, and fill the gap in this research direction of meteorological wind speed measurement. We study the regression relationship between the measured wind speed, standard wind speed, and tilt angle of the three cup wind speed sensor in a non horizontal wind field, and propose a magnitude transfer correction algorithm for the data of the three cup wind speed sensor in a measuring environment in a non horizontal wind field. We explore the algorithm design direction of the next generation three cup wind speed sensor, provide ideas for its type evaluation as a measuring instrument, and lay the groundwork for future research on similar application scenarios.
