Development and Application of Interference Data Anomaly Instrument for Geoelectric Observation

    摘要
  • 摘要: 地电观测过程中，由于受漏电和观测系统故障会引起干扰数据，如突跳、台阶、超差等，这些干扰数据不易被快速判断，需要做大量检查工作才能完成。为解决此问题，研制了地电观测干扰数据检查仪，能实时记录仪器工作状态和地电场变化，当出现干扰时调取相应干扰时段的秒数据或分数据，通过对干扰数值波形特征分析，进而快速判别并排除干扰。实践应用表明，该仪器对干扰异常能够较好识别，提高了排查效率。

     

    Abstract: In the process of geoelectric observation, the data are easily disturbed by by leakage and observation system fault, such as sudden jump, step, out-of-tolerance and so on. These interference data is difficult to judged quickly, and need a lot of inspection work to complete. The instrument can record the working state and the change of the geoelectric field in real time. When there is interference, the second data or minute data of the corresponding interference period can be retrieved, and the interference can be identified through numerical analysis, thus eliminating the abnormality and improving the efficiency of interference data troubleshooting.
