组件式雨水情应用集成平台设计与开发

Design and development of component-based hydrological application integration platform(CHAIP)

针对水利防汛中雨水情应用存在的多源数据难以集成、应用单一以及表现力不足等特点,采用组件式软件开发技术、框架技术及三维仿真等现代信息技术设计并开发了面向水利防汛的组件式雨水情应用集成平台,在多源数据集成的基础上实现雨水情应用集成。基于组件对雨水情集成平台体系结构进行设计,由数据层、服务层、应用层和客户层构成,其中,应用层采用模块化思想,不同的应用功能模块分别进行设计。通过在陕西省水利防汛中实际应用表明,组件式雨水情应用集成平台具有可扩展性、较好三维表现效果、易操作性、实用性及实时性等特点,能够为水利防汛提供实时的决策支持服务,具有较好的应用前景。

This paper designs and develops a component-based hydrological application integration platform（CHAIP） of flood control to implement standardization of hydrological information processing and application integration on this platform,avoiding disadvantages of the existing system,hard to integrate multi-source information and single mode of representation in flood control.The platform adopts key techniques of component-based coding,object-oriented language,framework,and three-dimensional simulation.Its architecture consists of a data layer,a server layer,an application layer and a client layer;different functional models at the application layer are designed separately with a modularization idea.Application in a case study of flood control in Shaanxi province shows that the platform is good in extendibility,three-dimensional performance and real-time application,and very easy to operate.Thus,CHAIP provides a support to processing,analysis and decision making in flood control with a good prospect in applications.
