【摘要】 在现代中国经济不断发展的过程中,越来越多的大城市所容纳的人口也在逐年递增。想要使人们的生活变得更加地便利,城市中建筑物的内容就要更加趋于多样化。比如当建筑物面临火灾时的疏散以及相关方面的完善,就是一个很重要的内容。以前应急照明的位置是固定不变的,只能够实现最基本的疏散功能,如果在面临火灾的时候,出现了一些错误的指示或者指导,可能会对人员的生命和财产安全造成很大的影响。所以应急照明疏散系统急需完善动态监控的功能。如果优化了这一点,就会更大限度地降低疏散的时间,从而大幅度地提高疏散的效率。很多大型的公共建筑在设计的时候,为了在突发情况发生时,及时做到人员的疏散,通常会配备对建筑物的内部结构非常熟悉的引导人员。当发生突发状况,需要人们更快地撤离的时候,这些引导人员的任务是非常繁重的,且仅仅依靠这些人员的指示,并不能最大限度地达到人员快速疏通的效果。因此,依靠设备让受困的人员更迅速的转移到安全的地区,是设计这项智能应急照明疏散系统的宗旨。这篇文章论述了一种无线传感应急照明系统的设计。这种传感系统能够做到智能化的控制,系统当中的信息是通过协调器和路由器等进行传递的。在这当中,协调器还能够进行节点信息的采集和多种信息的发送。在得到信息之后,通过上位机进行命令的重新转移,而协调器的节点存在的主要目的是为了能够将这些信息及时的发送到应急照明节点中。而路由器存在的主要目的是为了能够将这两种节点之间的数据进行转换。在这个系统当中,还有内部无线传感网络芯片的使用。除此之外,内部的应急照明系统还实现了协调器的节点组织。在植入温度采集以及光照的传感器芯片之后,还能够通过对周围环境的检测,及时做出反应。上位机软件存在的主要目的是为了可以让各个节点的参数汇集完成的情况下及时地了解火灾预警。这个系统能够对现在的应急照明系统做一些功能上的补充。现如今的照明系统难以实现人为的控制,在遇到问题的时候,反应的效果也并不是非常明显。而这项设计会使原有照明系统在固有基础上,得到大幅度的优化。更多还原

【Abstract】 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.更多还原
