The Design And Implementation Of A ZigBee-based Smart Fire Warning System

Since the 21 st century,our country has entered the age of rapid development,with the rapid growth of population and economy,more and more fire safety problems also appeared,one of them is from increasing population density of the increase of building fire control difficulty problems,such as the fire spread fast,indoor evacuation harder,outdoor personnel rescue difficult,etc.The traditional fire protection system in buildings usually adopts the alarm system of bus layout,which is not smart and sensitive,and the layout is too complicated,which makes the installation and later maintenance cost high.With 5G and WiFi gradually improvement of the information technology and the continuous development of Internet technology,people on indoor intelligent fire control technology and precision requirement also have higher requirements,therefore intelligence community and smart home based on the technology of Internet of things has become a hot research direction at home and abroad,intelligent fire control technology also arises at the historic moment.Based on the above research background,this paper proposes an indoor intelligent early fire warning system based on ZigBee technology.ZigBee technology is a kind of wireless communication applied in a short range with low transmission data rate.Compared with other traditional communication technologies,it has the characteristics of low power consumption,low cost,high efficiency and high reliability,and has a broad application prospect in the modern Internet of things technology.Through the hardware design and software programming of each wireless module in the system,the system can realize the building and indoor fire monitoring and early warning.The main research of this paper includes the following aspects:First of all,the author analyzes the background,overseas and domestic research status of intelligent fire control system.And then the author puts forward an intelligent fire control system integrating information collection and node control.The author breaks down the process of module developing and analyses the working principle and connection rules of each module.Secondly,the author analyzes and designs the system circuit,wireless communication module,sensor module and node control module in terms of hardware which complete the hardware part of the system.In terms of software,data acquisition program is designed for each sensor.The networking,sending and receiving programming of ZigBee is completed on the basis of Z-Stack protocol stack.The author launches the experiment after the completion of software and hardware design.Finally,the function of the system is evaluated.According to the results and data of each group of experiments,the author analyzes whether the system could meet the design requirements of indoor fire extinguishing.
