摘要
现阶段自动气象站风速现场校准量值无法进行溯源,从而导致风速现场校准数据的准确性和可靠性得不到保证。究其原因,是由现行的现场校准方法和现场校准设备工作原理决定的。为了解决这一问题,使用"量传"风速传感器和叶轮风表进行中间数据传递,在校准时用叶轮风表作为校准的标准设备,并利用了三杯式风速传感器的线性特点,把台站风速传感器的现场校准量值溯源到了大型风洞皮托管上,并且通过大量试验证明了该方法的正确性,为新的自动气象站风速现场校准规范制定和校准设备的完善提供有力的理论依据。
The field calibration values of wind speed from automatic meteorological stations cannot be traced back,so that the accuracy and reliability of the field calibration data cannot be guaranteed.A investigate is conducted on the causes,which are determined by the current field calibration methods and the working principles of field calibration equipment.In order to solve this problem,the value transfer of wind speed sensors and the impeller wind meters are used to carry on the intermediate data transmission.In calibration,the impeller wind meter is used as the standard equipment.Using the linear characteristics of three-cup type wind speed sensors,the field calibration values of wind speed sensors are traced to the large-scale wind tunnel pitot tube,and through a great number of experiments,the validity of the method is proved,so as to solve this technical problem.The method provides a theoretical reference for making new specifications for the field calibration for wind speed from automatic meteorological stations and for perfecting of calibration equipment.
