基于RFID的智能挂锁的设计与实现

AbstractIn the era of Internet of things,home intelligent is the general trend,andlock is an indispensable part.This design password lock has the advantagesof convenience,high security,forgetting to take the key,etc.This design is aRFID Based RF smart lock.This design originates from the fact that I oftenforget to take the key in my daily life.After market investigation,I found thatthe Bluetooth lock often needs to be connected first and then unlocked.Theprocess takes 2 to 3 minutes.Although these Bluetooth locks can open thedoor without the key,it does not save time,so I want to design a smart lockthat can unlock the door more quickly.This design is composed of hardwareand software,mainly using RFID technology and infrared remote controltechnology.In this design,the hardware part is composed of STC89C52single chip microcomputer system,4 4 matrix keyboard,LCD1602 liquidcrystal display module,re522 card reading module,and the software part isprogrammed with C language.It can read and write the card and manage theRFID card through the administrator password.The system has a variety ofways to unlock,RFID card can be used to unlock,infrared remote controlunlock,Bluetooth remote control unlock.Key words:RFID;single chip microcomputer;intelligent lock2
