Embodiment Construction

[0027] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0028] With the acceleration of urbanization, commercial districts across the country are rapidly increasing, and many of them are typical commercial districts with huge volume and complex composition. Scholars at home and abroad have established a three-level early warning index system with emergencies as the research object based on the research on related disaster-causing factors and related standards, and realized the classification and early warning of emergency risks in typical commercial areas; The evaluation method calcul...

Abstract

The invention discloses a typical commercial district risk early warning system construction and early warning grading classification method and device. The method comprises the following steps: recognizing a risk index of a target region according to a public safety triangle theory, so as to construct a risk early warning index system of the target region according to the risk index; calculatingthe weight of each index in the risk early warning index system by using an analytic hierarchy process, and evaluating the weight of each index by using a fuzzy comprehensive evaluation method to obtain an early warning value of each index; and obtaining a current risk early warning level of the target area according to the early warning value of each index so as to carry out early warning according to the current risk early warning level. According to the method, graded early warning of different types of risks can be realized for different typical commercial districts according to local conditions.

Description

technical field [0001] The invention relates to the technical field of risk early warning, in particular to a method and device for constructing a risk early warning system in a typical commercial area and for grading and classifying early warning. Background technique [0002] In recent years, with the acceleration of rural urbanization and population urbanization, more and more rural areas have been transformed into urban areas, the urban population has continued to grow, and cities have continued to expand. Various commercial areas are no longer concentrated in the center of the city, but It has sprung up in various areas of the city like bamboo shoots. According to the differences in the construction volume, purpose and location of commercial districts, a typical commercial district can be defined as "huge in size, composed of many shopping malls, restaurants, hotels, office buildings and other commercial buildings, with sound internal public facilities, located in the c...
