Abstract

The invention discloses a tower crane risk accident prediction method and system based on case-based reasoning. The method comprises the following steps: constructing a tower crane accident case database; wherein the tower crane accident case database is composed of accident information of a plurality of tower crane accident cases; constructing a tower crane accident case similarity index system;calculating the weight of each index in the similarity index system by adopting a G1 algorithm; determining a calculation method of similarity of different types of single indexes in the tower crane accident case similarity index system; calculating the similarity between the target case and each tower crane accident case in a tower crane accident case database by adopting a discrete variable secondary scoring method or a discrete variable tertiary scoring method according to the weight, and sorting all tower crane accident cases from large to small according to the similarity; selecting the first N tower crane accident cases to form a similar accident case sequence; and determining a risk accident prediction type of the target case. According to the invention, the prediction accuracy of risk accidents possibly occurring in a single target case can be improved.

Description

technical field [0001] The present invention relates to the technical field of risk accident prediction, in particular to a tower crane risk accident prediction method and system based on case reasoning. Background technique [0002] With the continuous development of the construction industry, there are more and more high-rise building constructions, and the construction of high-rise buildings is inseparable from the use of tower cranes. In recent years, tower crane safety accidents have occurred frequently. On July 22, 2017, a tower crane collapsed at a construction site in Zhuhai District, Guangzhou City, resulting in 7 deaths and 2 serious injuries. Tower crane accidents will bring large casualties and huge property losses to the whole society. Therefore, the prediction of tower crane risk accidents and the adoption of effective prevention and control measures have become the focus of attention in the field of construction. [0003] The existing tower crane risk analysi...
