| Abstract: | A geomagnetic FHD-2B proton magnetometer was installed at the Yongan station in October 2009.After years of stable operation,a large set of reliable precursor observation data has been generated. The instrument is operating smoothly at present,and the data profiles contain few burrs,small lines,and low noise.However,the instrument may encounter a variety of problems in its daily observation process,influencing its normal operation.In order to improve the quality of the instrument''s maintenance, it is necessary to conduct a summary of the commonly occurring instrument problems and their corresponding solutions.The FHD-2B proton magnetometer comprises communications technology, computer technology,data acquisition,and computer software processing:the magnetometer is a set of integrated and comprehensive technology.Each functional unit is independent and connected to one another, so that the failure of any unit can affect the overall instrument performance,leading to a decrease in the continuous collection rate,accuracy,or quality of the observation data.This study describes a particularly problematic situation at Yongan station,including repair methodology that involves the investigation of communication failures and faulty data acquisition for the FHD-2B proton magnetometer data, and the subsequent improvements,so that the readers can share the experience of equipment maintenance, as well as the implementation of an improved equipment maintenance program.Interference factors, such as meteorological factors,human disturbances,and unknown reasons,are discussed.The improved maintenance program,which enhances the quality of observation data,requires the station staff to document in the instrument observation log,the data preprocessing and the weather changes,providing detailed and reliable information for forecasters to accurately identify and analyze disturbances and seismic anomalies.Scheduled and effective magnetometer equipment maintenance and the keeping of daily observation log records are critical for ensuring reliable and long-term observation data is obtained for seismic monitoring. |
