基于单片机的安防监控系统研究与设计

北京理工大学珠海学院2020届本科生毕业论文Research and design of security monitoring system based on MCUAbstractIn recent years,with the continuous development of science and technology,many families have entered the era of intelligence.No matter at home or in the office,as long as you operate on your mobile phone,you can control all the electricalappliances.This idea is no longer out of the sky.In the era of intelligence,the use ofacoustic communication,optical communication and other technical means,accordingto people's daily preferences,can make electrical appliances intelligent,which greatlyfacilitates people's lives.In the era of intelligence,the use of electricity is not unimportant.The use ofsome high-power electrical appliances increases the probability of circuit failure,which leads to a series of problems and even fires.This type of news is not lacking innews reports.For this phenomenon,this design mainly studies the fire alarm system,through the use of STC89C52 series chips,as well as smoke sensors,temperaturesensors and other components,designed a device that can mainly achieve firemonitoring.It can monitor the concentration of abnormal gas in the air to determinewhether there is a fire,and feed back some abnormal conditions to the operator.Thereare few similar devices on the market,and the system has strong practicability.Thereis no doubt that it has a large market demand.Keywords:STC89C52:Temperature sensor:Gas sensor:Security system
