Abstract: The information node of municipal seismic stations is an important element of seismic monitoring and prediction system. It collects and transmits the monitoring data of seismic stations, shares seismic information with provincial information node, and plays as an intermediate hub between provincial information node and county information node. The standardization transformation of municipal information node is a favorable guarantee for seismic data analysis and prediction. This paper summarizes the standardization transformation of information node of Linyi seismic stations in terms of network structure, software and hardware equipment deployment, daily maintenance management and safety management, which provides an excellent reference for the upgrading and transformation of information nodes to other municipal seismic stations.
