基于网格平台的水文预报集成应用模式

Integrated Application Mode of Hydrological Forecasting Based on Grid Platform

在分析目前洪水预报及洪水预报系统存在的问题的基础上,提出了洪水预报的综合集成应用模式,即基于平台、组件、主题、可视化的洪水预报集成应用模式。基于WebService技术将洪水预报模型及模型参数率定方法组件化并发布成Web服务。采用知识图关联信息,组织应用过程中的信息,描述事件、应用主题和业务流程。基于面向服务的体系架构(SOA)和J2EE平台技术架构,采用中间件、网格、WebService、综合集成研讨厅等技术构建洪水预报综合集成服务平台。在平台下开展洪水与集成应用,通过实例检验洪水预报集成应用模式。

Through analyzing current problems in flood forecasting and flood forecasting system, the thesis presents an integrated application mode for flood forecasting based on platform, component, subject, and visualization technology. Flood forecasting models and parameter estimation methods are developed as components and are published as web services. Knowledge maps are used in information association and organization to describe matters, application subject and business process. Furthermore, an integrated service platform is established with technologies of service-oriented architecture, middleware, grid, web service and integrated discussion hall. The integrated mode has been already veri？ed through real application cases.
