自动土壤水分观测仪的实验室检测方法

Detection Method of Automatic Soil Moisture Observation Instrument in Laboratory

随着我国气象高质量发展,气象观测和检定已向自动化全面推进,自动气象站已配备自动土壤水分观测设备,以减小人工观测误差,实现自动测量土壤水分含量,配备的传感器为FDR型自动土壤水分传感器。为保障气象观测数据的准确性,自动土壤水分传感器需每2年进行1次实验室检测,通过检测结果得出仪器性能,判定是否能继续投入使用。通过论述基本原理、主要参数及检测流程,明确自动土壤水分的检测要求,对在标准条件下的自动土壤水分观测仪器进行标定,确保投入使用的仪器观测所得数据可信。

With the high quality development of meteorology in China,meteorological observation and verification have been fully promoted to automation,automatic soil moisture observation equipment has been equipped with automatic meteorological station,to reduce manual observation error and achieve automatic measurement of soil moisture content,FDR automatic soil moisture sensor has been used.In order to ensure the accuracy of meteorological observation data,the automatic soil moisture sensor should be tested in the laboratory every two years,and the performance of sensor can be determined by the results,and determine whether to be used.By means of expounding the basic principle,main parameter and detection process,the detection requirement of automatic soil moisture were explained,and the automatic soil moisture observation instrument was calibrated under standard conditions,to ensure the reliability of the observation data.
