Analysis of data interruption characteristics at Beijing Earthquake Early Warning Stations
摘要
Abstract
The continuity of data from early warning stations is a key performance indicator for earthquake warning work,which directly determines the speed and quality of the output of earthquake warning results.To clarify the continuity status of data from the early warning stations of Beijing Earthquake Station,continuous records from 199 early warning stations of Beijing Earthquake Station from December 1,2023 to February 29,2024 were selected for statistical analysis from the perspectives of data interruption frequency and duration,with a focus on analyzing stations with severe interruption phenomena.The analysis results show that about 5.5%of early warning stations have serious data interruption phenomena,and the characteristics of interruption are not the same.Among 6 types of devices,3 types of observation devices did not show serious data interruption phenomenon.Some 3G/4G wireless stations have more stable data continuity compared to some fiber optic stations.关键词
