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.
