摘　　要：针对风向传感器校准误差问题,提出一种风向传感器校准方法。该方法首先对传感器系统循环数据进行采集与预处理,然后引入一种传感器误差校准方法,进而实现传感器的校准。选取5种风速,比较不同校准方法的实际应用效果,当风速为30 m/s时,研究技术的最大测量误差为0.481,明显小于传统测量方法。此外,通过比较风速角监测结果,发现研究技术监测结果更接近实际结果,表现更好。由此可见,研究技术具有出色的应用效果,可为气象部门的管理与设备维护提供重要技术支持。A wind direction sensor calibration method is proposed to address the issue of calibration errors in wind direction sensors.This method first collects and preprocesses the cyclic data of the sensor system,and then introduces a sensor error calibration method to achieve sensor calibration.Select 5 different wind speeds to compare the actual application effects of different calibration methods.When the wind speed is 30 m/s,the maximum measurement error of the research technique is 0.481,which is significantly smaller than traditional measurement methods.In addition,by comparing the wind speed angle monitoring results,it was found that the research technology monitoring results are closer to the actual results and perform better.It can be seen that research technology has excellent application effects and can provide important technical support for the management and equipment maintenance of meteorological departments.
