Analysis of Influencing Factors on Background Noise of Yongan Magnetometer
This paper investigates and analyzes the main factors that affect the unexplained crash and background noise of Yongan Station FHD-2B instrument from the aspects of observation environment,technical system,observation instrument and human noise.The results show that the observation environment of Yongan Station is good and the gradient meets the requirements.The main reasons for excessive background noise and unexplained crash of the geomagnetic instrument are the long running time of the in-strument and the deterioration of internal performance.After the transformation of the industrial computer,the failure rate is greatly reduced,and the data noise is also greatly improved after the update of the instrument,which effectively improves the maintenance experience and observation data quality of Yongan geomagnetic instrument and provides reference for the observation and maintenance of the station.
