Evacuation Route Ant Colony Algorithm In BIM Model Achieve Research

With the rapid development of era,the population of the city is increasing,at the same time,the building groups that meet people's lives are also rising quietly,people's security has become the biggest challenge in the new century.With the occurrence of accidents(such as fire,gas leakage,dust explosion,etc.),it is the focus of attention to make an effective emergency plan before the accident.Effective emergency plan cannot be separated from personnel safety evacuation.However,whether the evacuation path is reasonable has become the problem that needs to solve.According to the traditional evacuation method,people can only rely on the experience and theoretical data to calculate.It can not satisfy people's intuitive understanding and knowledge of evacuation path.The emergence of BIM(Building Information Modeling)makes the building undergo a transformation of informationzation.People can understand the basic situation of the building in real time and obtain detailed information of the key points to provide technical protection for emergency evacuation.This paper realizes the effective combination of ant colony algorithm and BIM technology.This paper starts with the analysis of current research status of BIM technology and ant colony algorithm.By looking up and reading a large number of references,the definitions and related applications involved in this paper are explained.At the same time,the development platform of this paper is introduced and the development test of C# programming language is completed.Then Revit secondary development technology is applied to implement the extraction of BIM model of architectural information work,and the extracted building information is used as the limited condition of the ant colony algorithm to realize the final calculation of the evacuation route.The relative optimal evacuation path is obtained by calculating the results,and the evacuation path of the three-dimensional roaming display.In the face of large unknown public places,the optimal evacuation path provides a scientific basis for the safety engineers to select a reasonable evacuation route,and help construction engineers to provide theoretical basis for building safety in the early stages of architectural design.In the development environment of information age,the research of this paper is of great significance.
