摘要随着社会的快速发展，经济水平的不断提高，各种高楼大厦如雨后春笋般拔地而起，意外火灾事件也随之频频发生，对于人们的生命安全和生产生活都造成了极其严重的影响。另外，一些码头、大型仓库等地也极易发生火灾，由于储存物资过多，一旦发生火灾，火势蔓延迅速，受灾面积广，扑救难度大，将会带来巨大的损失。因此，做好火灾的监测与预警工作显得格外重要。

火灾预警系统如今成为了物联网技术的一个重要研究方向。本文主要利用物联网技术与温湿度传感器技术相结合来实现对仓库火灾的预警，应用Zigbee技术、网关、Internet和计算机软件等技术，构建了基于物联网技术的仓库火灾预警系统。本系统包括硬件设计和软件设计两部分，硬件主要由CC2530最小系统设计，传感器模块，数据处理模块，电源管理模块以及通信模块五大部分组成；软件包括系统监测流程图设计和系统功能设计两大部分。72716

Design of Fire Alarm System Based on Internet of Things

Abstract

With the rapid development of society, the continuous improvement of economic level, all kinds of tall buildings have sprung up, fire accidents also subsequently occur frequently, for the safety of people's life and production and life caused extremely serious impact。 In addition, some of the pier, large warehouses and other more are prone to fire, due to the storage of goods too much, once the fire, the fire spread rapidly wide affected area, fighting difficult, will bring huge losses。 Therefore, doing a good job of monitoring and early warning of fire is very important。 

Fire alarm system has become an important research direction of the Internet of things technology。 In this paper, the use of networking technology with the temperature and humidity sensor technology to achieve the combination of the warehouse fire warning, application of ZigBee technology, gateway, Internet and computer software technology are constructed for warehouse fire alarm system based on the technology of Internet of things。 The system consists of two parts: hardware design and software design, hardware are mainly composed of five parts such as CC2530 minimum system design, sensor module, data processing module, power management module and communication module。The software includes the monitoring system design of the flow chart and system function design of two parts。 

The design has 14 figures, 4 tables, 24 references。
