摘　　要：介绍一个基于UNIX类操作系统的紧密结构地震台网中心核心数据处理系统。该系统适用于复杂结构的数字地震台网中心,支持以比较低的成本,可靠地完成地震台网中心的核心任务,可以接收来自串口和网络的实时地震波形数据,支持虚拟数字地震台网组网要求的节点数据服务功能等。该系统的数据服务协议具有实时性高、通讯可靠、适应范围广等特点,可以满足包括地震预警在内的所有实时地震数据应用的需要。系统结构紧凑,自动化程度高,安全,稳定,系统伸缩性大,可以满足台站数目不大于100个的数字地震台网中心的需要,同时也可以作为大型数字地震台网中心的处理节点,构成大型数字地震台网中心的数据处理系统。A data processing system of digital seismic network based on Unix-like operating system with tight core is introduced in this paper. It may perform all core features of data processing for a seismic network in low cost. It may receive real time data from serial ports and dedicated networks or public networks and support real-time node data service which is requested by virtual seismic networking. The real-time data serving protocol used in this system has characteristics of real-time, reliability, and wide suitability etc, it may meet the needs of all real time seismic waveform data applications, including earthquake early warning. This core system is tight in its structure, highly automatic, safe, stable, extendable, etc. It is suitable for centers of digital seismic network with less than 100 stations and complicated structure. At the same time, it may also be used as a node in the center of a large scale seismic network to form a large data process system for it.
