利用Excel创建雷达图进行风向传感器数据偏差分析

Analysis of data deviation of wind direction sensor using radar chart in Excel

目前的自动气象站风向传感器检定工作只停留在对比示值误差,即:示值误差的最大值不超过±5即为合格。这样的检定方式虽然可以满足目前气象台站的使用要求,但是检定数据却不能形象的反应风向传感器的数据偏差,不利于日后的分析总结。目前也没有一种直观的方式可以表达风向数据偏差情况,针对这种情况,本文提出了一种利用Excel软件创建雷达图,对自动气象站风向传感器数据进行偏差分析的方法。

At present,the calibration of wind direction sensor of automatic weather station is based on comparison of indication errors.If the maximum error is less than ±5°,the sensor is qualified.Although this calibration method meets current requirements,the test data cannot give a vivid image,and is not conducive to the future analysis and summarization.There is also no intuitive way to reflect data deviation of wind direction sensor.Therefore,this paper presents a method for analyzing data deviation of wind direction sensor of automatic weather station using radar chart in Excel.
