火灾预警系统的设计与实现

Design and Implementation of Fire Warning System Based on Single Chip Microcomputer

火灾的发生往往不可预料,且一旦发生就会对人民生命财产安全造成重大破坏。因此,设计一款智能且高效的火灾预警系统对于人们能够安全和健康地生活有着重要的意义。设计了以STC8H1K08单片机为控制核心的火灾预警系统。在该系统中,采用DHT11温湿度传感器检测环境的温湿度,用MQ-2烟雾传感器检测环境烟雾浓度,用火光传感器检测有无火光,采用OLED显示各个数据,并可实时将温湿度、烟雾浓度、火焰等信息通过Wi-Fi模块传送到移动端。此外,在系统中还能对上述参数值依据实际需求设置,当这些值超过设定阈值时触发蜂鸣器报警。

Fire early warning has become an indispensable guarantee in people's production,life and work.Therefore,if we design an intelligent and efficient fire early warning system,it is of great significance for people to live a safe and healthy life.This paper designs a fire early warning system with STC8H1K08 single chip microcomputer as the control core.DHT11 temperature and humidity sensor is used to detect the temperature and humidity of the environment,MQ-2 smoke sensor is used to detect the ambient smoke concentration,fire light sensor is used to detect the presence or absence of fire light,and OLED is used to display various data.At the same time,temperature and humidity,smoke concentration,flame and other information are transmitted to mobile app in real time through Wi-Fi.In addition,the key can set the temperature and humidity,smoke concentration and flame.When these values exceed the set limit,the buzzer will alarm.
