Embodiment Construction

[0060] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that this embodiment is only for illustrating the present invention, rather than limiting the protection scope of the present invention.

[0061] The embodiment of the present invention is based on the two-way reference feature fire risk assessment method of Hausdorff distance, such as figure 1 shown, including the following steps:

[0062] S1: Extract the fire risk factors of the building to be evaluated, quantify the risk factors, and form the feature vector of the building;

[0063] S2: Construct a two-way reference vector, a reference fire feature vector and a reference safety feature vector according to the feature vector of the building;

[0064] S3: Perform Hausdorff distance calculation on the feature vector of the building and the constructed two-way reference vector to obtain the risk assessment level of the building.

Abstract

The invention discloses a bidirectional feature fire risk assessment method and a bidirectional feature fire risk assessment system based on Hausdorff distance. The method comprises the steps: firstlycarrying out the risk factor feature vector extraction of a to-be-assessed building; then, judging the similarity degree of the feature vectors of the to-be-evaluated building and the bidirectional reference vectors through the Hausdorff distance, and obtaining the fire risk level of the to-be-evaluated building; carrying out risk thermodynamic color scale value conversion on the fire-fighting risk level again, so that three-dimensional visual display can be carried out conveniently; and finally, displaying the risk thermodynamic color code in a three-dimensional visual model graph, so that the building risk is visually presented, and accurate risk positioning and targeted management are achieved. The fire risk assessment problem is effectively solved, scientific guidance is provided forfire management work. The probability of fire disasters is reduced, and the fire management level is improved.

Description

technical field [0001] The invention relates to the technical field of public fire safety, in particular to a Hausdorff distance (Hausdorff distance)-based two-way reference feature fire risk assessment method and system. Background technique [0002] With the acceleration of urbanization, the fire situation faced by the society is becoming more and more serious. In recent years, new situations and new problems faced by firefighting work are increasing day by day, and fire risks and prevention and control difficulties are increasing, making fire safety management difficult; in addition, complex fire factors and diversified large buildings make the fire rescue situation more difficult. It's getting tougher. Facing the increasingly severe rescue situation and difficult fire safety management, it is imperative to study a fire risk assessment system. The results of fire risk assessment provide scientific references for staff to achieve targeted management, precise prevention a...
