【摘要】：綜合減災中,協(xié)同研判是一種十分有效的災情匯聚分析手段�，F(xiàn)有災情協(xié)同研判系統(tǒng)存在災情研判水平層次低、研判活動缺乏系統(tǒng)化管理、數(shù)據(jù)同步共享方式造成網(wǎng)絡傳輸壓力大等問題。數(shù)據(jù)集中的復制式模型是一種高效的協(xié)同系統(tǒng)模型,有效提高系統(tǒng)可靠性和降低網(wǎng)絡傳輸量并兼顧空間數(shù)據(jù)一致性和數(shù)據(jù)存儲效率。本文詳細介紹了災情研判技術(shù)流程和關(guān)鍵技術(shù),充分利用復制式模型特點設計并實現(xiàn)了一個基于復制式模型的災情協(xié)同研判系統(tǒng)。實驗表明,該系統(tǒng)穩(wěn)定可靠,能有效滿足分布式、異步或同步災情協(xié)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.
