The Design and Realization of Seismic Real-time Waveform Data Collection System

摘要:

随着国家地震烈度速报与预警工程和地震信息化工程不断建设，地震台站数量激增，观测数据量呈指数型增长。为实现海量地震台站实时观测数据汇聚到国家中心，缩减数据汇集流程，本文开展了基于分布式技术（Hadoop技术框架）地震实时波形观测数据汇聚系统的研究，实现地震观测数据的云端采集，并以网络中断重连机制和实时流数据双链路接入机制保证数据的可靠传输，实现地震观测数据汇集的统一调度和高效管理。

Abstract:

The National Earthquake Intensity Bulletin and Early Warning Project and The China Earthquake Administration Informatization Project cause the number of observation stations to surge,and the observation data has increased exponentially. In order to achieve the aggregation performance to gather massive seismic real-time waveform data from the source of the stations to the national center and reduce data gathering processes in the future,this paper develops a research on the seismic real-time waveform data aggregation system based on the distributed technology(Hadoop technology framework). The seismic real-time waveform data aggregation system has two main achievements:①Realizing seismic real-time data gathering from the cloud; ②Realizing seismic real-time data dispatching and management efficiently through interruption reconnection mechanism and real-time streaming data dual-link access mechanism to ensure the stability of data transfer.
