Problems solved by technology

However, this technology does not involve the impact of geospatial information on disaster events, and does not conduct in-depth analysis of the occurrence, evolution, rescue and recovery of emergency events affected by geographic information. The use of GIS platform only plays the role of visualization of geospatial information.

Embodiment 1

[0029] Such as figure 1 As shown, the present embodiment includes: an emergency event information integration module, an emergency event information filtering module and an emergency early warning grid division module, wherein: the emergency event information integration module receives the emergency geographic information from the GIS database and from the relationship Emergency event attribute information of type data, and generate spatial relationship information according to GIS data processing, and output spatial relationship information and event attributes to the emergency event information filtering module after integrating the spatial fact constellation model according to keywords, and emergency event information filtering The module filters and preprocesses the spatial fact constellation model according to the distribution difference of spatial information and outputs the processed spatial fact constellation model to the emergency warning grid division module. Fact C...

Abstract

The invention belongs to the technical field of Internet disaster pre-warning, and relaters to an emergent pre-warning grid dividing system and method based on space correlation analysis. The system comprises an emergency information integration module, an emergency information filtering module and an emergency pre-warning grid dividing module. According to the method, emergency geographical information is taken as an analysis clue of an emergency pre-warning layout, firstly, an expression mode of emergency space relation information is designed; then the emergency space relation information is extracted, and the emergency space relation information and structural property information of an emergency are integrated to build a space fact constellation model; accordingly to a filtering algorithm based on frequency difference, non-sense space relation information is eliminated; finally, by means of hybrid space correlation rule digging, space characteristics influencing the emergency are obtained and constitute an emergent pre-warning geographical grid covering different emergent pre-warning levels. According to the emergent pre-warning grid dividing system and method, integration of emergency peripheral space relation information and property information is achieved, a concept tree is used for describing space relation information and event property information, and the space fact constellation model for integrating non-structural data and structural data of the emergency is achieved.

Description

technical field [0001] The present invention relates to a method and device in the technical field of Internet disaster early warning, in particular to an emergency early warning grid division system and method based on spatial correlation analysis. Background technique [0002] Since emergency emergencies occur in a specific geographic space, the early warning, mid-event response, and post-event recovery of disaster emergencies can all be managed and planned with the support of geographic information systems. There are many academic literatures on this research, of which there are two representative types: The first type is the technical application of geographic information system (GIS) in early warning and decision-making of disasters. For example, use geographic information system to visualize the area distribution of chemical pollution on the river bank, and then use the trend evolution model to carry out decision-making evaluation (Jiang et al., 2012); the network anal...
