深层地温传感器检定维护及数据对比分析

本文对谷城县国家基本气象观测站检定过程中发现的备份站深层地温套管内积水问题进行了处理,对深层地温温度传感器进行了周期检定,并对检定前后的深层地温数据进行了对比分析。结果表明,备份站深层地温80、320 cm套管积水主要是由于降水引起的,套管内积水会引发深层地温数据异常偏高,其中80 cm深层地温偏高13.21℃,320 cm深层地温偏高13.18℃。在对积水进行处理后,备份站深层地温恢复正常,两站深层地温数据一致性较好。同时,为了确保深层地温传感器的正常运行和观测数据的准确可靠,应按照规定的时间进行周期检定和维护工作,尤其要做好日常维护和降水后检查深层地温进水情况。

An Analysis of The Data Before and After Verification of Deep Geothermal Sensor

This paper deals with the problem of water flooding into the deep geothermal casing of the backup station found during the verification process of the national basic meteorological observatory in Gucheng County, Xiangyang City. The periodic verification of deep geothermal temperature sensor is carried out, and the data before and after the verification are compared and analyzed. The results show that the water accumulation in the casing of 80 CM and 320 cm is mainly caused by precipitation. The water accumulation in the casing causing abnormal high ground temperature data in the deep layer, of which the ground temperature is 13.21 C higher than normal in the 80 cm depth and 13.18 C higher in the 320 cm depth. After the treatment of the accumulated water, the deep ground temperature of the backup station returns to normal, the data of the two stations have good consistency. At the same time, in order to ensure the normal operation of deep geotemperature and the accuracy and reliability of observation data, periodic verification and maintenance should be carried out according to the stipulated time, especially the daily maintenance and water inflow check after precipitation.
