地震前兆数据库维护是台站日常工作的重要内容，如果台站节点数据库发生故障，会导致数据交换缓慢，甚至无法从上级数据库得到原数据，对台站数据造成损失，所以加强台站前兆数据库的日常维护很有必要。以福建省地震局永安地震台为例，介绍基层地震台前兆数据库及日常维护经验，为其他地震台前兆数据库稳定、健康、可靠运行提供借鉴与参考。%Precursory database maintenance is very an important content of station routine. If station node database failure, data exchange will become slow, even making it unable to obtain the original data from the host database, resulting in losing the data of station. So strengthening routine maintenance of station precursor database is necessary. Taking Yongan Seismic Station as an example, the management experience of grass-roots information node of seismic station is introduced. It can provide useful information and reference for the stable, healthy and reliable operation of other stations.
