[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.
