【摘要】：综合减灾中,协同研判是一种十分有效的灾情汇聚分析手段。现有灾情协同研判系统存在灾情研判水平层次低、研判活动缺乏系统化管理、数据同步共享方式造成网络传输压力大等问题。数据集中的复制式模型是一种高效的协同系统模型,有效提高系统可靠性和降低网络传输量并兼顾空间数据一致性和数据存储效率。本文详细介绍了灾情研判技术流程和关键技术,充分利用复制式模型特点设计并实现了一个基于复制式模型的灾情协同研判系统。实验表明,该系统稳定可靠,能有效满足分布式、异步或同步灾情协同研判的要求。
[Abstract]:In comprehensive disaster reduction, collaborative research is a very effective means of disaster situation convergence and analysis. There are some problems such as low level of disaster evaluation, lack of systematic management of research activities, and high pressure of network transmission caused by synchronous data sharing. The replicative model of data set is an efficient cooperative system model, which can effectively improve the reliability of the system, reduce the amount of network transmission and take into account the consistency of spatial data and the efficiency of data storage. This paper introduces the technical flow and key technology of disaster research in detail, and designs and implements a disaster collaborative research system based on replicative model by making full use of the characteristics of replicative model. Experiments show that the system is stable and reliable and can effectively meet the requirements of distributed, asynchronous or synchronous disaster collaborative study.
