基于数据跟踪分析河北电磁台网环境干扰因素
Analysis of environmental interference in Hebei electromagnetic network based on data tracking
摘要
Abstract
In this paper, taking the precursory data tracking analysis of product information from seismic network of Hebei Province in 2008 to 2016 as the data source, the major environmental disturbances in Hebei electromagnetic network are analyzed and summarized. In analysis, all kinds of interference factors, causes and dynamic variation curves are studied, the typical examples of electromagnetic network environment interference are extracted, the examples of effective and technical support for the accurate judgment of precursory variation are provided. At the same time, according to the interference causes, the measures for reducing the interference or avoiding interference are discussed, in order to obtain accurate geophysical field observation data to do further research. In the course of the study, the database table structure of the data trace analysis information is also studied, and some improvements for the better service are put forward.关键词
