摘　　要：利用运营商网络将地震监测数据实时传输至本地数据中心进行在线处理是全球各地地震台网的通用做法,IRIS和GFZ等机构提供了基于SeedLink协议的地震数据共享服务器,用户既能通过互联网快速获取数据到本地,又能通过Seiscomp和Earthworm等系统进行实时地震监测。目前国内测震台网使用NetSeis/IP协议和Http协议进行数据分发,通过Jopens MSDP软件进行在线处理。由于国内外采用不一样的数据传输协议,国内数据流不能直接接入Seiscomp和Earthworm等系统使用。为解决这个问题,介绍了NetSeis/IP和SeedLink等国内外主流地震数据实时传输协议,对协议指令及数据请求方式进行了详细描述,提出了一种基于RingServer快速搭建轻量级SeedLink实时数据流服务器的方法,可实现SeedLink服务器功能,一方面满足Seiscomp和Earthworm等国际地震监测系统的数据接入需要,另一方面为我国地震数据在线共享提供参考。It is a common practice for seismic networks around the world to transfer seismic monitoring data in real time to local data centers for online processing by using operator networks.Organizations such as IRIS and GFZ provide seismic data sharing servers based on the SeedLink protocol,which allows users not only to quickly access data to the local via the Internet,but also to perform for real-time seismic monitoring through system such as Seiscomp and Earthworm.Currently,the domestic seismic station network uses the NetSeis/IP protocol and Http protocol for data distribution,and uses the Jopens MSDP software for online processing.Due to the different data transmission protocols used at home and abroad,domestic data streams cannot be directly connected to systems such as Seiscomp and Earthworm.To solve this problem,this paper introduces the mainstream seismic data real-time transmission protocols at home and abroad,such as NetSeis/IP and SeedLink,describes the protocol instructions and data request methods in detail,and proposes a method to quickly build a lightweight SeedLink real-time data streaming server based on RingServer,which can realize the function of SeedLink server.On the one hand,it meets the data access needs of international seismic monitoring systems such as Seiscomp and Earthworm,and on the other hand,it provides a reference for online sharing of seismic data in China.
