基于STM32单片机的家庭智能火灾安全系统研究

AbstractIn recent years,our standard of living has improved,given the rapiddevelopment of society,the development of electronic technology andcomputer hardware and software technology.The building is more andmore complex,a large number of electrical appliances and complexstaggered lines make our daily life have potential safety hazards,so thefire safety problem has become a big problem in our life to be solved,andmore and more fire systems and fire extinguishing systems have emerged.A small fire alarm system of intelligent home based on single chipmicrocomputer is designed,which realizes the functions of smoke alarm,temperature abnormal alarm,infrared detection and external interruption.In terms of hardware selection,stm32f103c8t6 single chip is used asthe main control chip,which integrates temperature sensor (LM75A),smoke gas sensor (mq-2),micro human body sensor PIR,active buzzerand 6 x 6 x 6 light touch switch,etc.the program is written to collectthe real-time temperature and smoke concentration data information ofenvironmental species through the sensors of each module,and then thesingle chip is used The machine stores and processes the data,and thencontrols each module element according to the design logic to makecorresponding countermeasures to eliminate hidden dangers and avoidaccidents as much as possible.Keywords:STM32 single chip microcomputer sensor Intelligencefire alarm system
