Common modeling method and system of heterogeneous disaster events

Abstract

The invention relates to a common modeling method and system of heterogeneous disaster events. The method comprises the steps of building a disaster event meta-modeling frame, building a mode structure of a disaster event meta-model and building a heterogeneous disaster event information model. The method and the system have the advantages and positive effects that the problems that existing heterogeneous disaster events lack effective description means and information models are not uniform are solved; the disaster event meta-model is built; four metadata components and eight-tuple node information description models are developed and the mapping relations between the geography markup language, the sensor model language, the event pattern markup language, sensor network common data information models and an event meta-model are designed; compared with existing disaster event management modes, the disaster event meta-model in the method and system provided by the invention comprehensively describes related information of the heterogeneous disaster events, thus providing supports for unified management and accurate discovery of the disaster events and proving that the method is beneficial to modeling of the heterogeneous disaster events and is more practical and reliable in disaster even management.

Description

technical field [0001] The invention belongs to the technical field of geographic information services for smart cities, and in particular relates to a general modeling method and system for heterogeneous disaster events. Background technique [0002] Frequent disasters have brought us serious disasters, which not only caused huge direct economic losses, but also greatly affected people's production, life and life safety, seriously impacted social economic and political life, and became the foundation of social development. Significant constraints (see literature 1). However, due to the interdisciplinary and cross-domain nature of disaster events, different event information modeling methods between different departments and applications make it difficult to be compatible between systems, forming "information islands", which brings huge challenges to information sharing and interoperability in the emergency field. obstacle. [0003] At present, there are many studies on di...

AI Technical Summary

Problems solved by technology

[0005] (1) For different types of disaster events, there is currently no modeling mechanism that can uniformly and comprehensively describe heterogeneous disaster event information, and there is still a lack of a disaster event element that can fully describe disaster event information and reflect its differences. Data model to realize cross-domain disaster event information sharing and interoperability, and expand metadata items according to the heterogeneity of different types of disaster events;

[0006] (2) For the description of disaster event information, the current description of disaster event information is limited to the description of specific types of event basic information and early warning information. The modeling object is single and the methods are different. The content of metadata information is incomplete and the expression is not uniform. There is a lack of a unified and standardized modeling tool and system, and it is impossible to systematically describe disaster events under a unified framework
