Design And Implementation Of Seismic Data Sharing Service Platform To Earthquake Industry User Oriented

Seismic data is an important basis for human understanding of the earthquake.Lots of seismic data supporting,which both on the CEA to carry out various businesses plays a positive role,but also can promotes the industry researchers to conduct interdisciplinary research,promotes the development of earthquake science and technology.Therefore,making full use of seismic data is the key work of seismic information construction.Since 1966,CEA has set up an earthquake monitoring network covering almost all over the country.Due to the characteristics of earthquake science data,covering many disciplines,long time span,dynamic and heterogeneous data structure.The data volume,performance and function of service industry is always the key demand of the construction of the sharing of data.Basis,relying on the "National Science and technology support of Earthquake Science Data Sharing Project(503130108)",this paper constructed earthquake science data sharing platform for earthquake industry,providing zero barriers,standardization,multi-level and multi means information service,to a greater extent reflected seismic data efficiency,prepare data for big data and seismic combination.Main research achievements include:1)The earthquake science data sharing service platform constructionThis paper completed the construction of shared service platform.Based on defining the bottleneck analysis and system research of the existing system,on B/S architecture,making use of the MVC mode's SSH(Spring,Struts2 and Hibernate)framework and the Ajax framework to integrate the electronic map database,database and all Web application services(data retrieval,visualization and download service).Based on the seismic industry network that has some safety measures,industry users,providing diversified services for nationwide earthquake science data on its products storage,management,retrieval,download and visualization.It has many characteristics,such as cross platform,high polymerization,low coupling,low threshold and so on.2)Standardization of seismic data sharing and exchangeThe platform provides a unified,zero barriers,standardize the service mode under the guidance of earthquake science data sharing project developed by China Earthquake Administration with reference to the implementing regulations,and with reference to guide related standards for seismic data management,sharing format and database storage specification developed for seismic industry data,and the national scientific data sharing project requirements.3)Design and implementation of various services in earthquake science data sharing platformThe design and implementation of data sharing services that took into account the fully mature and stable information technology,guarantees the stability and easiness of the platform,minimizes the seismic industry user data acquisition and application cost,promotes the exchange of earthquake science data sharing benefits.The seismic data sharing service network platform provides users with standardization,multi-level and multi service with INTERNET.Firstly,The platform classified data of resource pool,fully analyzed of data structure properties,designed different dimensions of the data retrieval service.Secondly,according to different data,showing the depth of its connotation to enhance the user experience of data based on Web targeted visualization system.Thirdly,on the basis of access to resources volume,providing real-time and offline download two the way to save time,cost.Fourthly,standardizing data format download resources to reduce the cost of application.Although this paper built the data sharing platform completely,and the platform has been put into trial operation,but it has many deficiencies,the need to increase the high standard module of data retrieval service,visualization services,big data,which can improve process performance.Only in this way the platform can provide comprehensive one-stop full service for industry users.
