Abstract：Based on the statistical summary of the fault response during the station operation and maintenance of the National Earthquake Intensity Quick Reporting and early warning project in Cangzhou area in 2022,the causes of different kinds of faults are analyzed and the treatment measures are summarized.According to the classification of ground motion signals,the interference encountered in the operation and maintenance process of Cangzhou is divided into transient interference,high-frequency interference and temperature interference.The noise analysis of data changes before and after the interference elimination is given to the operation and maintenance processing examples,so as to provide reference for the identification and investigation of similar interference in station operation and maintenance.
