Research On Fire Emergency Lighting Power Management System Based On Ant Colony Algorithm

Because of the development of China’s fire protection cause and the promotion of the public’s fire awareness,fire emergency lighting system,as an important facility to ensure the evacuation of personal and fire rescue in the event of fire,has been applied in all kinds of buildings.Meanwhile,the research on fire emergency lighting power management system has also received wide attention.Fire emergency lighting power management system for emergency lighting lamps and lanterns and unified management of standby power supply,emergency lighting system status display and alarm function,,help to improve the working efficiency of the emergency lighting system and emergency power supply,the current domestic power management system research is given priority to with cooperation between colleges and universities as the leading factor,joint research and development of enterprises,and has made great progress,but we compared with foreign products,still exist on the system reliability and precision far difference.Starting from the problems found in the preliminary investigation,this paper studies the emergency lighting power management system.Firstly,in view of the single function and low utilization rate of emergency lighting,this paper transforms the existing emergency lighting,combines the fire emergency lighting and the floor daily lighting,and designs the intelligent emergency lighting with power supply.Secondly,in order to meet the needs of emergency lighting system in terms of power management,this paper designs a set of remote power management system,adopting a based on Thevenin equivalent circuit model and the fusion algorithm of extended Kalman filtering algorithm for lamps and lanterns with battery power estimates that make up the power management system in the defect of low power estimation precision,realize the monitoring the status and the function of the built-in battery fire emergency lighting lamps and lanterns;aiming at the problem that the power management system does not respond to the abnormal nodes in a timely manner,this paper proposes a system inspection scheme based on ant colonyalgorithm,and determines the inspection path of the system to the power nodes from the perspective of time and space.Finally,on the basis of the above research,a graphical monitoring interface for human-computer interaction is developed to achieve the goal of emergency lighting system power management.The hardware test,software test and simulation experiment of the fire emergency lighting power management system are carried out in this paper.The power management system runs well and the estimated error of battery energy storage state is controlled within 3%.This paper proposes a power node inspection scheme based on ant colony algorithm,which can effectively shorten the inspection distance of nodes,quickly detect abnormal nodes,and improve the system stability and speed.
