摘要
采用ATMega16单片机为基础,构建了一个以WIFI网络作为连接手段的家用型防火防灾报警系统。根据实际需求,系统采取主从机模式,设计有配对和无线断开警报功能。主机用作警报,配备液晶显示屏,LED指示灯和蜂鸣警报器。从机用作采集数据,采用了高低电平中断检测的原理,获取数据,并且通过WIFI网络无线传输到主机,达到警报的目的。
This paper introduces a family fire alarm system,which uses the ATMega16 microcontroller technology. The WIFI network connects the systems to each other. According to the actual demand,this paper adopts the master- slave design mode,which contains pair and disconnecting alarm functions. The master is used for alarm,which contains LCD,LED and beep. The slave is used for collecting data,which uses the function of high- low voltage interrupt detection to obtain the data. The slave transfers the data through the WIFI network to the master and it achieves the alarm.
