摘要随着社会经济的飞速发展,当前时代人民生活水平的提高,人口规模也在不断增加,各种高楼大厦也逐渐增多起来。每年都有大量的火灾事件发生,造成人员伤亡和经济损失,尤其是位于野外的森林、油库、码头等,这些建筑本身就是为特殊目的设计、占地的面积很广、有各种用途的设备在其中,有火情的概率远大于其他建筑,如果有火情出现没有很快察觉,就会造成上级消防部门无法及时得到火灾消息,产生更大火灾,而且会给消防救援带来巨大的压力和困难,给当地带来巨大的损失,更严重的会造成当地居民或消防员的丧生。所以,健全危险地带的火灾预警系统,开发危险地带的火灾预警系统刻不容缓。38517
本文针对目前的森林防火提出了结合物联网的设计方案, 利用火焰热释电传感器技术,阐述了野外火灾探测选择使用红外技术的原因,之后探讨了热释电红外传感器的结构、工作原理及特点,设计了一个基于热释电红外传感器的火灾探测系统。设计了基于物联网技术的火灾监测系统。将各自独立的火灾传感器节点通过ZigBee技术组成一个信息网,并经由GPRS网络将数据上传给现场监控中心和远程服务器,现场监控中心和服务器根据上传的各个监测点的数据,在后台的管理软件上实时的显示各个监测点的工作状态,得到比较真实的现场状况,用于火灾灭火,使相关人员做出正确的处理方案,大大提高了火灾的预警和消防能力,最大程度地减少火灾造成的人员及财产的损失。

Abstract With the rapid economic development,the current era of people’s living standards improve, population size is increasing, a variety of buildings is gradually increasing.These buildings are rising at the same time,fire danger has also increased significantly.Annually are has large of fire event occurred, caused personnel casualties and economic loss, especially is located in field of forest,and Depot,and Terminal,due to its structures special, and fire partition huge, and facilities complex, fire hidden many, once occurred fire and cannot timely found, often fire cannot right timely reported, led to fire spread, caused major loss,not only will to fire rescue brings huge of pressure and difficult ,while may caused serious of economic loss and social effects, even also will led to personnel casualties.Therefore, the perfect outdoor buildings,facilities, research field of automatic fire detection system is necessary.
In view of current forest fire is proposed according to IOT designs, fire detection technology focuses on IR, describes the wild fire detection using infrared sensor was discussed after the structure, working principle and characteristics, designed a fire detection system based on Pyroelectric infrared sensor. Design fire monitoring system based on Internet technology. Will respective independent of fire sensor node through ZigBee technology composition a information network , and via GPRS network data upload to monitoring center amd remote server, monitoring center and server according to upload of all monitoring points of data, in background of management software real-time of displayed all monitoring points of work state, get compared real of site status, for fire, makes related personnel made right of processing programme,greatly improve has fire of warning and fore capacity ,best to minimize human and property losses caused by the fire.
Keywords:Internet of things ZigBee Fire monitoring Pyroelectric Sensor
