自动气象站地温线路老化引起数据异常故障判断分析

Discriminate Analysis on Abnormal Fault Data due to the Aging Ground Temperature Circuit of Automatic Weather Station

通过对南宁国家基本气象站CAWS600SE型自动气象站地温线路老化引起地温数据异常的分析,介绍了如何根据故障判断的依据和流程,采用对比法、测量法和替代法,依次对地温传感器、地温变送器、防雷板、采集器和数据线路等环节故障进行排除的方法,确定导致地温数据异常的故障点并对故障予以排除,并提出对异常数据的处理方法,为类似自动气象站故障的排除提供参考。

Based on the analysis on abnormal fault CAWS600SE automatic weather station in Nanning, data due to the aging ground temperature circuit of the fault judgment basis and process was introduced. Using comparative method, measuring method and alternative method in turn to the faults in ground temperature transmitter, temperature sensor, lightning protection board, terminal and data line were excluded to determine fault point and rule out the fault, And put forward the abnormal data processing method to provide reference for the similar situation.
