Research On Intelligent Evacuation Controller Of Emergency Lighting System

In recent years,all kinds of complicated large intelligent buildings is increasing,the traditional emergency lighting evacuation system fixed instruction mode cannot have satisfied the evacuation of modern architectural work,in most cases cannot play its evacuation function on real significance,so now the electrical professional design task is more difficult,these are prompted intelligent fire evacuation emergency lighting system become the new trend of development.Quite a number of people during a fire can't identify or killed by error indicator evacuation route.As a result,a fire,the fire of according to the development of real-time dynamic monitoring and dynamic intelligent emergency lighting in the instructions to evacuate system study is very necessary,reduce the evacuation time,avoid blindly escape.In public emergency evacuation of the optimal route choice problem as the research point,the fire alarm system and emergency evacuation system is analyzed,the intelligent controller has carried on the detailed understanding and research,it is the core of emergency lighting system.Intelligent controller is shouldering the collected signals,and to choose the optimal evacuation path.After the fire,the fire smoke,temperature and so on will be detector to detect the fire signal,and the transmission of real-time information to the fire control room,fire controller receives the fire signal,after a series of calculation,the optimal evacuation route start light flow direction,namely by adjusting the evacuation instructions marked on the evacuation passageway pointing in the direction,make the evacuation indicator light flashes instructions,in turn for evacuees clearly indicate the direction of escape.At home and abroad recognized one of the best model of solving the shortest path problem with Dijkstra algorithm and Lloyd algorithm,but only apply to a smaller network diagram computation to solve.As people for the further research of intelligent bionic algorithm found a new intelligent bionic optimization algorithm of ant colony algorithm is very suitable for application in the building when the fire broke out for solving the shortest path choice.
