摘　　要：该文介绍一种基于STM32单片机的二维码门禁控制系统。该系统通过集成图像采集、二维码识别、数据通信和控制逻辑等关键模块,实现高效、安全的门禁管理。首先,系统利用GM65图像传感器捕捉进出人员的二维码图像,然后通过STM32单片机的强大处理能力进行二维码解码,从而获取其中的身份信息。接着,系统将解码得到的数据与One-Net云端信息进行比对,以判断进出人员是否具有合法通行权限。若权限验证通过,则门禁设备执行开锁操作,允许人员通行;若验证不通过,则系统拒绝开锁,并记录相关事件。该系统的引入,不仅提升门禁管理的效率和安全性,还降低了人为操作的错误率,为智能化、自动化的门禁管理提供新的解决方案。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.
