摘要: 随着中国科学探测台阵观测系统的建成,大规模流动地震台阵观测项目不断开展。其中,川滇地区安装的由约300台宽频带地震仪组成的地震台阵支持下的"活动地块边界带动力过程与强震预测"探测项目和中国地震局地球物理研究所在首都圈地区进行的约250台地震仪台阵实验探测项目最具代表性,这对流动数字地震台阵数据的有效管理和自动处理提出了前所未有的迫切要求。文中介绍了可用于流动地震数据管理和自动预处理的SeisComP软件及其数据的归档结构,针对台阵仪器众多、参数配置繁琐和数据处理环节复杂的特点,给出了基于SeisComP软件包台阵数据的一种高效管理方案,整合了数据格式转换和参数修正等环节,实现了台阵数据的自动归档和地震信息的自动提取,可以提高数据的管理效率,对台阵地震信息的及时发布和波形数据共享提供了良好的科研条件。

Abstract: With the establishment of China Seismic Array for Scientific Research,large-scale mobile seismic array observation projects have been carried out.One of the observation projects,named Dynamical Process of Active Block Boundary Belts and Strong Earthquake Prediction,consists of about 300 sets of broadband seismic instruments in Sichuan and Yunnan.And another seismic array for experimental survey equipped with about 250 sets of seismic instruments has been in operation in the capital area of China.As representative projects,an unprecedented urgent request was raised on the effective management and automatic processing for mobile digital seismic array data.The data acquired from mobile digital seismic instruments is stored in many scattered storage medium.For better storing,processing and use of the data,all the data should be archived in accordance with the requirements of a unified format.Seismic array data has unique characteristics of liquidity,density and relevance.It is necessary to ensure efficient management of many related parameters of array equipment.Ensuring an easy way to amend and change the observation data and pooling them to data center are also needed.Data management solutions to seismic network can not fully meet the actual needs.In this paper,SeisComp software which can be used for seismic array data management and preprocessing is introduced together with its data archive characteristic.A high efficient algorithm for seismic array data management is proposed based on SeisComP packages,which conforms data format conversion and parameter modification and realizes the automatic data archiving and pick-up.The method improves the efficiency of data management,and meanwhile,facilitates the data information distribution and waveform data sharing.
