Design And Implementation Of Seismic Analysis And Prediction Information Management And Service System Based On B/S

APnet is a dedicated network system which is used for changing information of seismic analysis and forecast in Chinese seismological industry.Time and growing business needs causes the system need to be upgraded.In this paper,a seismic analysis and prediction information management and service system based on B/S,namely,the new APnet is designed and realized.The new system realizes the transformation from the information exchange platform to working platform of seismic analysis and forecast.The research raises two key issues in the process of system design and Implementation and seeks solutions.Taking the research of the requirements of seismic analysis and prediction as a priority issue,firstly,this paper designs a service module from the perspective of the overall design of functional architecture.The service module includes consultation,project consultation,zero exception report,exception verification reports,forecasts card management,sequence directory,earthquake cases summary,earthquake emergency products and data exchange.Furthermore,the research designs data storage and business competence,and analyses the process of seismic analysis and prediction.Technical architecture selection and system optimization design solve the issue of the overall design of system technical architecture.The new system based on a SSH2+ExtJS4 development framework and adores a dual hot backup strategy to achieve data backup.At the same time,the new APnet upgrades the database management system and the application operation system.To meet the business needs of seismic analysis and forecast,the system makes great improvement in the aspect of function.Provided by the service module,the most important service is information sharing,management services,such as data query,uploading and downloading.It also provides data processing services to a part of the operations,such as zero exception report summary statistics,online interactive drawing based on GMT and fault online interpretation and visualization based on WebGIS.
