多源Internet准实时地震数据获取技术研究
|
摘要
为了不断提高监测能力,禁核试北京国家数据中心需要增加从Internet上获取相关敏感地区的地震台站监测数据。提出并实现了一种多源数据获取方案。该方案通过以多种方式同时从Internet上不同的台网中心获取同一台站的准实时地震监测数据,在禁核试国家数据中心本地拼接、剔除冗余数据,保障数据的获取率和可靠性。
To improve the monitoring capability for some sensitive areas constantly,the CTBT Beijing national data center(NDC) needs to obtain more and more data of seismic stations via Internet.A multi-source data collection program pacakge is prensented.The program can fetch seismic monitoring data from different network centers or data sources nearly in real-time in different ways,and then sort data by time,discard the redundant and convert them to CSS format.With this program,NDC can reliably obtain monitoring data of some seismic stations in time.
