地震前兆数据连续性及稳定性量化评价

摘要

鉴于因地震前兆仪器采样率提升而带来的数据量大、规模增加的状况，在前期实现陕西省地震前兆观测台站每日数据定时汇集的基础上，对汇集数据的连续性及稳定性进行量化分析。通过程序设计，实现对观测数据异常状态的自动检测，给出干扰数据剔除后各检测分量的稳定性评价结果，以数据库表格式保存。以期为数据共享服务提供基础依据，为地震台动态化管理提供信息支撑，为其他地震观测数据的相关研究提供技术支持。%In consideration of the situation that a massive increase in the amount of data caused by the improvement of the sampling rate of the precursor instrument,based on the daily data collection of all the precursor observation stations in Shaanxi Province,the study on the quality quantitative analysis algorithm is carried out from two aspects:continuity and stability. Through the designed program,the anomalies of the observation data are automatic detected and the complete rate is calculated. Finally,the stability evaluation results of each item of each station are given in the condition of removing interference data. All results are saved in the database in which tables are newly added and designed according the standard format of precursor database. In order to provide the basis for data sharing services,both information support for the dynamic management of the station and technical exploration for other related observation data are provided.
