一种可靠的地震台站数据传输方案设计与实现

Design and Implementation of A Reliable Data Transmission System for Seismic Stations

在我国禁核试核查体系中,国家数据中心需要稳定、可靠地近实时获取地震台站的监测数据,以保障日常的分析、监测能力。提出了一种数据传输方案,该方案通过从台站端的数据采集器或LISS数据源获取数据,生成CD1.1格式的数据;并采用CD1.1协议将数据近实时地传输至国家数据中心。

The CTBT Beijing national data center （NDC） plays an important role in China CTBT verification system, which require a stable, reliable data transport links to access the monitoring stations in order to protect the routine analysis and monitoring capabilities. A data transfer program , which can collect data from the LISS source or EDAS -24IP devices on the stations to generate CD1.1 format data and use CD1.1 protocol to transfer data to NDC in near real time is presented. The program is currently being implemented on some stations of the monitoring system.
