specific Embodiment approach

[0066] Such as image 3 Shown, the specific embodiment of the present invention comprises the following steps:

[0067] (1) Taking Shenzhen as the scope of assessment, according to the division of administrative regions of Shenzhen, Shenzhen has 10 districts and 74 streets in total. These 74 streets are used as the assessment unit for regional fire risk assessment of Shenzhen.

[0068] (2) Investigate the land use layout and fire safety status of Shenzhen City, refer to the fire risk assessment factor data table, investigate the basic fire situation, land use layout and fire safety status of each street, and collect the main fire hazards, regional characteristics, Data on urban building conditions, construction of fire brigades, and social and environmental conditions.

[0069] (3) Distribute index weight questionnaires to experts and citizens, conduct public consultation and expert decision-making through questionnaires, determine the relative weights of each factor index at...

Abstract

The invention discloses a regional fire risk assessment method based on a smart city, which comprises the following steps: S1, determining an assessment range and dividing an assessment unit; S2, constructing a fire risk assessment index system; 3, calculating that weight of each factor index; S4, constructing a quantitative model of fire risk assessment parameters, and quantifying the fire risk assessment parameters in the three-level indexes; S5, calculating the fire risk index of each evaluation unit, and evaluating the fire risk of each evaluation unit; S6, according to the fire risk assessment results of each assessment unit, the city fire risk level distribution map is drawn, and the fire risk assessment is carried out on the assessment scope. The invention can form systematic, scientific and objective evaluation to the real evaluation unit by constructing the fire risk evaluation index system with hierarchical structure, responding to the situation of the evaluation unit in various aspects at different levels, and quantifying the fire risk evaluation parameters.

Description

technical field [0001] The invention relates to the technical field of fire risk assessment, in particular to a smart city-based regional fire risk assessment method. Background technique [0002] With the rapid development of information technology, the construction of smart cities has gradually become the trend of urban development in the world today. Among them, smart public safety is one of the important contents of smart city construction. Fire protection, as the focus of smart public safety construction, has received widespread attention. Accurate understanding of fire risks can facilitate corresponding decisions to reduce or control fire risks and effectively respond to emergencies. event. [0003] At present, my country's research on risk and its evaluation is relatively late, and there are large differences in research in this area in various fields. In addition, statistical data is not perfect, and it is difficult to obtain scientific, reasonable and credible acci...
