基于STM32单片机的二维码门禁控制系统OA

This paper introduces a two-dimensional code access control system based on STM32 single chip microcomputer.The system realizes efficient and safe access control management by integrating key modules such as image acquisition,QR code recognition,data communication and control logic.First of all,the system uses the GM65 image sensor to capture the QR code images of people entering and leaving,and then decodes the QR code through the powerful processing ability of the STM32 single-chip microcomputer,so as to obtain the identity information.Then,the system compares the decoded data with the One-Net cloud information to determine whether people in and out have legal access.If the authority verification passes,the access control device performs the unlocking operation and allows people to pass;if the verification fails,the system refuses to unlock and records the relevant events.The introduction of this system not only improves the efficiency and security of access control management,but also reduces the error rate of human operation,and provides a new solution for intelligent and automatic access control management.
