Fire risk assessment method and device, terminal equipment and storage medium

Abstract

The invention discloses a fire risk assessment method and apparatus, a terminal device and a storage medium. The method comprises the steps of dividing a to-be-assessed region into at least one assessment unit; calculating a fire source distance between the center coordinate of each evaluation unit and the fire point coordinate; obtaining a fire feature value of each evaluation unit according to the fire source distance and the initial feature value corresponding to the fire type; respectively adopting an analytic hierarchy process and an entropy evaluation method to obtain a first weight value and a second weight value of the fire index of each evaluation unit; based on a random forest model, according to a fire index and the fire characteristic value, obtaining a contribution value of the fire index; obtaining a third weight value of the fire index according to the first weight value, the second weight value and the contribution value; and obtaining a fire risk assessment value of each assessment unit according to the fire index and the third weight value. According to the embodiment of the invention, the accuracy of a fire risk assessment result can be greatly improved.

Description

technical field [0001] The present invention relates to the field of risk analysis and assessment, in particular to a fire risk assessment method, device, terminal equipment and computer-readable storage medium. Background technique [0002] With the rapid development of the economy, the scale of the city continues to expand, various elements of production and living in the city and the population continue to concentrate, and various risks are highly concentrated, resulting in a substantial increase in the amount and difficulty of urban fire protection work, resulting in essential changes. Under some management modes and mechanisms, even if the management intensity is increased, its management efficiency cannot be significantly improved. Therefore, it is necessary to propose a fire risk assessment method to guide the optimal deployment of fire risk levels in urban areas and fire emergency rescue forces, and provide a scientific basis for fire prevention and control, multi-di...

AI Technical Summary

Problems solved by technology

This method does not consider the statistical results of historical fire data, and it is difficult to accurately judge the fire risk according to the fire characteristics of each area of ​​the city

In addition, because the determination of index weights in the traditional fire risk assessment system is greatly influenced by the subjective experience of decision makers, it is difficult to eliminate the influence of subjective factors on the fire assessment results, thereby reducing the accuracy of the fire assessment results
