北京理工大学珠海学院2020届本科生毕业设计Design of intelligent anti-theft alarm systemAbstractWith the development of the times,various smart devices are integrated into people'sdaily lives.Therefore,the communities around the world have begun to join the trend of thetimes in the smart community.The first to bear the brunt is the safety and intelligence of thecommunity.Every household will be more at ease with their own safety,and people's liveswill become more colorful.This article introduces the design of the intelligent anti-theft alarm system and thevarious challenges encountered in the design.The system uses a 51 single chipmicrocomputer,which is used to intelligently control the device in the design,and usesinfrared pyroelectric sensor detection If someone is approaching,find that someone isapproaching and control the buzzer and GSM SMS module to warn the user.The system hasthree modes,namely:emergency alarm mode,disarm and arm.In the emergency alarmmode system,the system handles emergency alarms without detecting whether there isanyone;in the arming mode system,it needs to detect whether there is someone,and ifthere is someone,it will not alarm if there is no one.The system is small in size,convenient for users to use,and has very reliable detectionand alarm functions.It plays a very important role in anti-theft and does not affect people'sdaily life.Keywords:51 single-chip microcomputer;infrared pyroelectric sensor;GSM short messagemodule
