Design Of Intelligent Emergency Lighting Evacuation System For Thesis Topic

China is currently in a period of great development of the city,city area in the center of the huge population,crowded space,with the development of modern city construction into a three-dimensional space according to the development trend,the comprehensive construction,convenience also brings new problems and building fire safety evacuation bring people.Emergency lighting traditional fixed evacuation system has been unable to meet modern building evacuation,in most cases can not play its true sense of the evacuation function,so now the task of electrical design work is more difficult,which prompted the fire emergency lighting intelligent evacuation system becomes a new developing trend.A considerable number of people are unable to identify or fail to indicate an evacuation route in the event of a fire.Therefore,when a fire occurs,can indicate the intelligent real-time dynamic monitoring and dynamic according to the fire development of emergency lighting system research is very necessary,reduce evacuation time,avoid blind escape.In building,especially in large public buildings,the most effective way to ensure rapid and safe evacuation is to familiarise people with internal structure and guide people to evacuate quickly or to enter shelters.However,the number of such personnel is often not guaranteed,and it is completely unrealistic to rely solely on personnel instructions.Therefore,we must rely on evacuation instructions,so that the trapped people can evacuate to the safe area with the fastest speed and the best evacuation route.This paper mainly introduces a design of intelligent emergency lighting system based on wireless sensor technology.The hardware part of the whole system consists of three parts: the node of the coordinator,the node of the router and the node of the emergency light(terminal node).Among them,the coordinator node is responsible for collecting the information and analyzing information collected by the emergency lighting nodes in the network,and forwarding the commands sent by the upper computer to the corresponding emergency lighting nodes in the network.The router node is responsible for forwarding packets between the coordinator node and emergency lighting node,emergency lighting node based on CC2430 chip +DS 18B20 chip temperature sensor,light sensor TSL2561 as the core,the internal node is responsible for collecting information about the state of the work and the external light,temperature and other information sent to the coordinator node.This system through the emergency lighting embedded wireless sensor network chip CC2430,the traditional emergency lighting emergency lighting system in the wireless network to join the coordinator node form,through the implantation temperature acquisition and illumination acquisition sensor chip so that each node can collect parameters of emergency lighting and its surrounding environment.The host computer software can detect the parameters of the emergency lighting nodes in the system and the dangerous situation of the surrounding environment in real time,so as to realize the fire warning function.This system will effectively solve the traditional emergency lighting emergency lighting system such as short service life,not easy to control,the system has single function etc.(can only provide lighting,does not have the fire alarm,emergency lighting system)in line with modern requirements.
