摘要
目前,由于作为自动气象站风速现场校准标准的风速校验仪的工作原理限制,造成风速现场校准时忽略了风速传感器的风阻系数,并且风速标准也无法溯源,从而导致风速传感器现场校准质量得不到保证。为了解决这一问题,本文通过对原有风项现场校准标准装置的研究,提出利用原启动风速现场校准标准装置改造后作为新风速现场检测装置,并总结出新风速现场检测装置的溯源方法及使用方法,最后通过实验验证其在自动气象站风速现场校准工作中的有效性和可行性。
At present,due to the limitation of the working principle of the wind speed calibration instrument as an automatic weather station wind speed field calibration standard,the wind speed field calibration ignores the wind speed sensor′s drag coefficient,and the wind speed standard can not be traced back,resulting in the wind speed sensor field calibration quality is not guaranteed. In order to solve this problem,this paper,through the research of the original wind field calibration standard device,puts forward the use of the original start wind speed field calibration standard device as a new wind speed field detection device. Finally,the validity and feasibility of this method in the field calibration of the wind speed of automatic weather station are verified by experiments.
