基于单片机的智能门禁管理系统的设计

AbstractIn today's modern life,access control facilities play an increasinglyimportant role.People use access control facilities to protect personal andproperty safety.With the further improvement of living standards and thesubstantial progress of modern science and technology,key door locksgenerally have problems with security and easy loss of keys.Ordinary doorlocks can no longer meet people's needs in life,and a new generation ofintelligent access control systems is coming out.Judging from the currentlyavailable door lock products,electronic combination locks,IC cardelectronic locks,etc.have gradually become the mainstream door locksolutions,but these often appear as a single solution,and composite solutiondoor lock products are generally less,and Access control system productsthat integrate more advanced biometric fingerprint recognition are rare.Theelectronic password lock of the single scheme cannot be unlocked if theparty forgets the password.Especially for the elderly with poor memory,remembering the password is a difficult problem.If there is an access controlsystem that integrates multiple solutions,the second solution can be usedwhen one of the solutions is not feasible.In this way,users have morechoices and can choose the familiar unlocking method.In this way,work andtravel efficiency will be greatly improved,and life satisfaction will be greatlyincreased.This design uses the STM32F103C8T6 single-chip microcomputeras the core to integrate a multi-program intelligent access control system.The system integrates three unlocking programs:electronic password,IDradio frequency card,and biological fingerprint recognition.Finally,thesystem has completed the integrity function test,and the functions of theintelligent access control system work normally and remain stable.At theend of the paper,a brief summary and expectations were madeKeywords:intelligent access control single chip microcomputer fingerprintidentification wireless radio frequency
