摘　　要：地震监测数据实时传输与汇聚是实现我国地震观测系统数据汇集处理工程化、运维管理智能化以及地震监测服务体系现代化的基础。新升级研发的地震监测数据实时传输与汇聚系统实现了地震监测数据的实时波形数据流服务,其具有丰富的适配器用于汇集地震监测台站或数据中心的实时地震波形或触发信息数据流。新系统支持快流/慢流混合传输和预警数据低延时传输,支持实时数据流智能监控和冗余热备。新系统流服务客户端为地震预警、地震烈度速报和地震波形数据归档等服务系统提供实时数据流服务。新系统从技术层面解决了大规模、多层级、不同类型地震监测台站和数据中心的实时数据流传输汇集共享问题,是我国地震监测事业实现信息化和现代化的关键。Real-time transmission and aggregation of seismic monitoring data is the basis for realizing the engineering of data collection and processing in seismic observation system, intelligentization in operation and maintenance management and modernization of the seismic monitoring service system in China. The newly upgraded real-time transmission and aggregation system of seismic monitoring data realizes the real-time waveform data streaming service of seismic monitoring data,and has rich adapters for collecting the real-time waveform or trigger data from seismic monitoring stations or data centers. The new system supports fast and slow streaming hybrid transmission,low-latency transmission of early warning data,real-time data streaming intelligent monitoring and redundant hot backup. The new system streaming service client provides real-time data streaming services for service systems such as earthquake early warning, seismic intensity rapid reporting, and seismic waveform data archiving. The new system technically solves the problem of real-time data streaming transmission,collection and sharing from or between large-scale, multi-level, and complex seismic monitoring stations and data centers, and is the key to the realization of informatization and modernization of seismic monitoring career in China.
