Flood emergency evacuation method based on real-time crowd data fusion

Abstract

The invention discloses a flood emergency evacuation method based on real-time crowd data fusion. The method comprises the following steps: 1, constructing a two-dimensional hydrodynamic model, and determining the range of a flood risk area and a safe area; 2, developing a position service interface, and accessing the Internet in an emergency state to obtain real-time crowd monitoring data; 3, developing a mobile application of flood emergency evacuation, and collecting user crowd filling data; 4, performing overlay analysis on the LBS real-time crowd monitoring data and the crowd data acquired by the mobile application by adopting a multi-source data fusion technology; 5, constructing a flood emergency evacuation model based on the real-time crowd fusion data, and dynamically planning a crowd evacuation route; and 6, pushing the flood early warning message and the evacuation route information to the crowd in the risk area. The method has the advantages that the accuracy and timeliness of crowd recognition are improved, and the efficiency and effect of emergency risk avoiding and evacuation of crowds in flood risk areas are improved.

Description

technical field [0001] The invention relates to the field of flood disaster crowd evacuation, in particular to a flood disaster emergency evacuation method based on real-time crowd data fusion. Background technique [0002] my country's super-standard flood events occur frequently, and the disaster risks caused by them are concentrated. Affected by climate change and human activities, the frequency and scale of super-standard floods have increased significantly in recent years. Coupled with the accumulation of population wealth in the process of urbanization, the destructive power of floods has increased dramatically. [0003] Emergency evacuation is an important non-engineering measure to deal with super-standard floods, including emergency evacuation planning, emergency evacuation plan, flood warning, evacuation, rescue and avoidance, etc. The current flood emergency evacuation methods adopted in our country are generally early warning through gongs and loudspeaker broadc...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a flood emergency evacuation method based on real-time crowd data fusion, improve the accuracy and timeliness of crowd identification, realize the intelligent optimization or generation of emergency crowd transfer schemes, and transfer routes for areas with pre-plans Real-time optimization, real-time generation of diversion paths can be realized for areas without a plan, which greatly improves the accuracy of emergency evacuation route planning and crowd transfer notification, and improves the efficiency and effect of emergency evacuation of people in flood risk areas; overcomes the notification efficiency of existing risk evacuation methods Low, slow emergency response, evacuation path, it is difficult to meet the new requirements of real-time crowd emergency evacuation of super-standard floods in changing environments
