摘要
通过对 2022 年沧州地区国家地震烈度速报与预警工程项目台站运行维护过程中的故障响应统计,分析不同种类故障原因并总结处理措施.针对地脉动信号分类,将沧州运维过程中遇到的干扰分为暂态干扰、高频干扰、温度干扰,并给出运维处理实例,对干扰排除前后数据变化进行噪声分析,以期为台站运维中类似干扰的识别及排查提供参考.
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.
