杯式风速传感器检定量值线性延伸方法探讨

现阶段由于多数地区的风洞硬件和软件条件有限,无法对自动气象站风速传感器进行30、40以及70 m/s等高风速段的检定,从而导致这些地区高风速段数据的准确性和可靠性得不到保证.为了解决这一问题,提出低风速段的检定数据线性延伸至高风速段的方法,并从三杯式风速传感器的物理原理出发,通过理论分析和实验验证两方面证明该方法的可行性,从而解决了这一实际问题,为新的自动气象站风速检定规范制定提供有力的理论依据.

Discuss of the method of linearly extending the calibrated value of cup anemometer

At this stage because most areas of the wind tunnel hardware and software conditions are limited,accuracy of 30,40 and 70 m/s wind speeds for AWS wind speed sensors can not be verified,so that the accuracy and reliability of high wind speed data can not be guaranteed in these areas.In order to solve this problem,In this paper,the method of linearly extending the test data of low wind speed section to high wind speed section is proposed.Based on the physical principle of the three-cup wind speed sensor,the feasibility of the method is proved by theoretical analysis and experimental verification,So as to solve this practical problems.The method provides a strong theoretical basis for making new test specification of the wind speed of Automatic meteorological station.
