基于网格技术的实时洪水预报建模系统

摘要

针对目前实时洪水预报建模过程中出现的数据获取难和计算力不足的情况,提出了基于网格技术进行建模的方法,以期通过网格技术实现信息的动态共享和计算力的有效整合.阐述了在网格环境下的建模体系结构,对任务解构、通信协议、调度算法等关键点做了详细说明.以渭河流域为例,对其进行实时洪水预报建模,证明了该方法的有效性.%Aiming at the present problem of data acquisition difficult and calculation insufficient appeared in the process of real-time flood forecast modeling, the method of modeling based on the grid technology was proposed to realize the dynamic sharing of information and the integration of computing power. The modeling system structure in grid environment was given, the task deconstruction, communication protocol and scheduling algorithm were explained in detail. Finally, the Weihe River Basin was taken as an example to prove the validity of this method.
