Study On Intelligent Evacuation Lighting Indication System Of Subway Station

Because the subway is more convenient than the ground traffic,subway has become one of the present most popular traffic tools. With more and more people choose subway travel at the same time,there is the subway station security problems of congestion and the personnel.Because of the MTR subway station and the complex structure,deep underground,no natural light intake and personnel density and other characteristics,in case of fire and other emergencies,will bring great difficulties to the emergency rescue,resulting in casualties and economic loss.An important part of the evacuation lighting indication system as a metro station emergency evacuation system,its function is the scene in the dangerous event guide the personnel safety,rapid,orderly evacuation.In order to further explore the safety evacuation in subway station staff,based on the original evacuation system,the subway station intelligent evacuation lighting indication system has done a more in-depth study.In this paper,taking the subway station as the application background,mainly do the research from four aspects:First,the emergency evacuation in subway station staff to carry out analysis and research,the paper proposed a design scheme of dynamic subway station evacuation lighting system.Second,in-depth analysis of the optimal path problem,and through the establishment of a suitable for underground multi factor change on weight path planning algorithm influence relation model to improve the Dijkstra algorithm,a design based on the Dijkstra algorithm and applies the dynamic path optimization algorithm in subway station personnel emergency evacuation,were also studied experimentally simulation and analysis of a metro station in Xi’an as an example.Third,according to the guiding role of evacuation lighting indication system of intelligent in the subway station is studied,using the cellular automata theory,builtsubway station evacuation model,combined with specific examples of subway station,discusses the evacuation lighting indicating guiding role on the evacuation process.Fourth,aiming at the dynamic path optimization algorithm and the subway station is designed based on the characteristics of intelligent STM32 processor as the core of the evacuation lighting controller;system consists of sensor detection module,CAN bus communication module,a central processor module,evacuation module,finally built a hardware experiment platform,and combined with the dynamic path optimization algorithm for the controller of the debugging and Realization of software.
