The Trapped Reproduce And Escape Route Optimization Design And Research Based On Virtual Reality Technology

At present,the fire alarm control systems commonly use evacuation lights and fire radio combined to evacuate people trapped in a building,this method does not have the positioning function.With the rapid development of economic construction,function and structure of the building have great changes the existing evacuation method is difficult to meet the requirements of social development and security.This paper relies on Jilin Province Science and Technology Department of Science and Technology Support Program key scientific and technological projects(Intelligent fire control system based on the networking technology),and studied the location of people trapped and reconstruction of buildings and escape route planning based on virtual reality.This paper presents a RSSI location algorithm and trapped feature information collection and transmission methods based on Zig Bee technology and combines CAN bus with an ID number distributed at each building to achieve the three-dimensional positioning of people trapped.Study on the Reconstruction of a building scene based on Unity3 D technology,Combined with data stored in the SQL database for real-time display of people trapped position and vital signs information,and combined with the A~* pathfinding algorithm in Unity3 D technology to help people trapped find out the most reasonable path.The results of this paper with the existing evacuation method combining can be able to locate trapped people,provide important information for the fire officers to search and rescue,help fire officials survey the scene to help evacuate people trapped,properly guide people trapped rapidly escape,and improve search and rescue efficiency.We can provide the best escape route for the trapped people help people trapped to complete the self-help.
