| 摘 要： | 研究了一种现场校准自动气象站风向测量系统的方法,即静态三点测量法。目的在于解决目前对风向示值校准角度覆盖不全,即风向校准区间缺测问题。根据格雷码盘式风向传感器的风向值对应码的编码原理和规律,采用理论分析和实验对比的方式论证该校准方法有效性和可靠性。在对风向测量系统的现场校准中,该方法能够很好的解决现场风向校准的区间缺测问题,并且校准数据准确可靠,在现场实际运用中切实可行。对于现行的室内检定风向示值,也建议采用该方法。

| Abstract: | The static three point measurement method is presented, which can be applied in field calibration of the wind direction measurement system for automatic meteorological stations, aiming to solve the problem of incomplete coverage of wind direction indication calibration angles, namely data missing during wind direction calibration. The validity and reliability of the calibration method are demonstrated through the theoretical analysis and experimental comparison according to the coding principles and regular pattern of wind direction values of the Gray Code wind direction sensor. The problem of data missing during the field wind direction calibration can be well solved by using the method, and the calibration data are accurate and reliable.The method is applicable during practical field application.This method can be recommended for indoor verification of wind direction values currently. |
