Large Logistics Warehouse Fire Evacuation Navigation Research And Design Of The Model

Large logistics warehouse because of its architectural characteristics,fire casualties,economic losses of more large than general construction,and its fire number is along with the development of the logistics industry is also increasing year by year.When this type of building fire personnel evacuation path planning application is very scarce.Fire evacuation navigation model was implemented.The model to obtain the large precise location information in the warehouse personnel,to provide real-time dynamic evacuation path planning services.Make personnel according to the scene environment to obtain the optimal path,greatly reduce the evacuation time.Paper mainly includes the following aspects:1,the contrast analysis of the current advantages and disadvantages of existing dozens of evacuation model,map in the environment,path planning algorithm,personnel on the choice of behavior model adopts the most conforms to the model design technology of application scenarios.2,model optimization for personnel evacuation way behavior guidance,as far as possible avoid loss due to the collision between the behavior of congestion and trampling behavior.To further reduce the fire evacuation time and risk.3,the design of the building fire evacuation model,makes the model according to the on-site environmental information of multi-source integration,dynamic real-time provide researchers with optimal evacuation path.The function of the model is realized by using Java development language,and the simulation model for the implementation and verification.Finally through the model simulation results compared with the simulation results of pathfinder,very good to verify the model in combination with the site information,personnel evacuation shunt,collision layered advantage,to complete the design expectations.
