深部探测数据共享平台的设计与研究

Design and study of deep exploration data share platform

深部探测是地球科学研究的重要手段,2008年我国启动了深部探测技术与实验研究(SinoProbe)专项,标着着我国深部探测计划的开始.在专项实施过程中,我们获得了中国大部分地区的深部地球物理探测、地球化学、地质等多种不同精度和方法的数据资料,由于探测方法不同导致了数据的异构性,数据获取始终是困扰研究人员的重要问题.在开展"Sinoprobe"研究专项的过程中,必须要解决数据的共享和交互问题.本课题通过对国内外著名的探测项目和地球科学数据平台的研究,探索数据共享和交互的解决方案,提出了基于SOA的深部探测数据共享框架,该框架的解决方案包括三部分:一是建立基于OGC标准统一的数据模型,将各类异构数据转换在一个地球框架中,实现互操作;二是利用Web Service技术构建分布式服务平台,实现从简单的客户端/服务器模型到复杂系统的扩展;三是利用Eclipse RCP的插件式开发技术,建立综合插件应用平台.最终解决了深部探测数据共享过程中存在的数据异构、系统异构及应用异构的问题.

The Deep Exploration is one of the important approaches to the Geoscience research.The special program of Deep Exploration Technology and Experimentation（ab.as SinoProbe） started in 2008 in China,which indicates the beginning of the Chinese deep exploration era.In the process of deep exploration we have obtained large kinds of data with different precisions by using the geophysical,geochemical and geological methods from most regions in China.Due to the different exploration approach it results the heterogeneity of data,and therefore data achievement becomes a serious problem to the researchers.The problem of data share and interaction has to be solved during the development of the SinoProbe research project.After studying most well-known exploration projects and the geoscientific data platforms in the global,we have explored the solution of data share and interaction,and then proposed the data share framework for the deep exploration project based on the SOA techonology.The solution of framework mainly includes three key parts.The first part is to construct a standard and unit data model based on the OGC than convert the heterogeneous data into the earth frame.The second part is to establish the distributed service by using the Web Service technology and to realize the extension from the simple client/service mode to the complex system.The last one is to develop a comprehensive application platform by using the plug-in based on the EclipseRCP.Ultimately,we have solved the problems about the heterogeneous data,the heterogeneous system and the heterogeneous application while sharing deep exploration data.
