Research And Design Of Fire Escape Simulation System Based On Unity3D

With the development of society and the improvement of economic level,there are more and more high-rise buildings with dense personnel,which is bound to bring great fire hazards.Once a fire breaks out,how to escape the trapped people and how the firefighters can rescue in time has become an urgent problem to be solved.Although this method is intuitive,a large amount of smoke generated during the fire will block the camera,resulting in monitoring and unable to locate the trapped person in time,thereby delaying the escape opportunity of the trapped person,and also causing firefighters to be unable to obtain the location of the trapped person in time,reducing rescue efficiency,causing unnecessary life and property damage.In order to solve the above problems,this paper designs a complete set of fire escape simulation system based on virtual reality.Relying on the industrial technology research and development project of the Development and Reform Commission of Jilin Province(BIM-based application research of fire rescue and big data escape planning system for high-rise buildings),this paper designs a fire escape simulation system,and studies the positioning of trapped persons and the reconstruction and escape path planning of trapped persons based on virtual reality.This paper uses UWB positioning technology to realize the positioning of trapped persons and the update of trapped personnel information by combining the base station and the tags carried by the trapped persons.The fire escape simulation system based on Unity3 D was studied,combined with the trapped personnel information stored in the My SQL database to realize the reconstruction of the trapped personnel,and combined with the A* pathfinding algorithm to help the trapped people find the most reasonable path that can avoid various obstacles and fire areas.Compared with the traditional fire alarm control system,the research results of this paper can locate the trapped people,and realize the reconstruction of the trapped people through Unity3 D,which provides the rescue team with the location information of the trapped personnel and the nearest exit location,which improves the rescue efficiency.At the same time,it can generate escape routes for trapped people,guide trapped people to escape,and complete self-rescue.
