智能门锁的软件设计与实现

北京理工大学珠海学院2020届本科生毕业设计或论文ABSTRACTThis design mainly uses STC89C52 single chip microcomputer and Keil single chipmicrocomputer software to program the whole system to carry on the system control.Thesystem includes master control module,fingerprint module,display module,data storagemodule,human-computer interaction module,alarm module and wireless module.With thecooperation of these modules,the system can realize the functions of input passwordunlocking,fingerprint unlocking,SMS unlocking and so on.The system takes the STC89C52 single chip microcomputer as the core,uses the matrixkeyboard to carry on the password output and the input,realizes the human-computerinteraction this,also uses the AS608 fingerprint module to input the fingerprint to carry on theidentification,may update the fingerprint information or deletes the fingerprint information.Using LCD12864 LCD screen to realize the relevant operation steps and prompt informationdisplay;using relay module simulation to realize unlock prompt;buzzer can alarm accordingto the situation;AT24C02 can store system password and fingerprint information.Whenentering password or fingerprint information,a single piece of information will be judged andcompared The original set of parameters,paired successfully can unlock.Because of the needfor remote control of access control,in the head of household is not at home,some outsiderscan press the access control through the remote GSM module remote unlock,remote controland monitoring preparation.This system uses the Keil software to design each program,at thesame time the whole hardware system in the Proteus environment simulation test,the resultshows:achieves the anticipated design effect.Keywords:Single-chip microcomputer;Fingerprint identification;LCD 12864;GSMmodule
