摘要： 国家数字地震台网47个数字化地震观测台站的地动实时观测数据,通过卫星信道传送到国家数字地震台网中心,再经信号分配器传至7台实时处理机。47个台的信号分成3个区域以3组计算机互为实时热备份的方式接收和处理地动波形数据。

关键词: 数字地震台网, 硬件, 接口

Abstract: The real time seismic data of 47 seismic stations are transferred to the NCDSN (National Center of Digital Seismic Network) by VSAT satellite. The real time seismic data are split into three copies and receiv ed by sev en computers, which backup each other. Theses sev en computers are desig ned in two binds of configuration. One configuration is that 47 seismic stations are divided into three groups: Northeast, Southeast and Northwest. The other configuration is that 47 seismic stations are treated as one group.

Key words: NCDSN, Hardware, Interface
