中文摘要：

针对传统的火情监控系统采用有线方式具有布线困难、维护费用高和抗干扰能力弱的缺点，提出了一种基于物联网和SOM算法的火情监控报警系统；首先，根据物联网的全面感知、可靠传递和智能处理的三个特性将系统分为终端节点、路由器和监控中心三个部分，然后对终端节点和监控中心的硬件进行了设计，并对MAC层协议、网络层协议、监控中心软件进行了设计和分析，采用SOM算法对传感器采集的数据进行融合分类；系统测试表明文中系统可以正确、实时地采集温度、湿度和烟雾等火情信息，并在其基础上进行融合将火灾分为5类，当火灾处于萌芽阶段时就发送消息给相关人员进行应急处理，具有很强的实时性。

英文摘要：

Aiming at the traditional fire monitoring system using the wired method has the defects of wiring difficulty, high cost for main tain and low antiinterference ability, a fire monitoring alarm system based on Internet of things and SOM algorism has proposed. Firstly, the system was divided to sensor node, router and monitoring center according the three characters such as comprehensive sense, reliable de livery and intelligent handing. Then the hardware of sensor node, coordinator node and the GPRS network gateway was designed. Finally, the MAC＇layer protocol, the network protocol and monitoring center software were designed, and the SOM algorism was defined to classify the data collected by sensors. The system test shows our system can collect the information of humidity, temperature, humidity and smoke information and then the data was classified by SOM algorism, according to the classification result the related persons will be alarmed to manage further, the method in this paper has strong real time ability.
