翻斗式雨量传感器现场校准相关问题探讨

Discussion on the Problems Related to the Field Calibration Method of Tipping Bucket Rainfall Sensor

为了使雨量传感器现场校准方法更好地应用于实际工作,根据翻斗式雨量传感器的特点、现场校准的工作经验及实验数据,发现并分析了《自动气象站现场校准方法》的不足,并在此基础上提出了最大允许误差的表述方法应为相对误差,以及在传感器分辨力不同时应增加重复性测量次数两点修订意见,从而进一步完善翻斗式雨量传感器现场校准指标和方法,为改进其现场校准方法提供了依据。

In order to make the on-site calibration method of rainfall sensor more suitable for practical work,according to the characteristics of tipper type rainfall sensor,the work experience of on-site calibration and experimental data,the deficiencies of"On-site Calibration Method of Automatic Weather Station"were found and analyzed,and on this basis,the expression of the maximum allowable error should be relative error,and the number of repeated measurements should be increased when the sensor resolution is different,so as to further improve the field calibration index and method,which provides a basis for improving the field calibration method.
