在对GStar-1型自动土壤水分观测仪运行中出现的问题进行分析归纳的基础上,针对该型土壤水分观测仪的自身结构特点及其测量原理,提出场地维护、仪器维护及故障排查处理的方法。通过这一系列的维护手段,可保障仪器观测数据的代表性,降低数据异常情况的发生概率,当出现数据异常情况时也可采用故障解析方法,快速查找故障所在,便于及时发现、解决问题,可减少数据缺报、误报的可能,这都将使仪器发挥其最佳的效能,提供更好的自动化土壤
On the basis of analyzing and summarizing the problems occurred in the operation of GStar-1 automatic soil moisture observer, this paper proposes a site maintenance, equipment maintenance and troubleshooting for the structure and measuring principle of this soil moisture observer method. Through this series of maintenance measures, the representativeness of instrument observational data can be ensured and the probability of occurrence of abnormal data can be reduced. When an abnormal situation occurs, a fault analysis method may also be used to quickly find the fault and facilitate the timely detection and solution of problems. Reduce the number of missing data, false positives, which will enable the instrument to play its best performance, to provide better automated soil
