QR二维码在公司访客门禁中的应用

随着物联网技术的不断发展,门禁系统的更新和升级已经成为一种必然趋势。针对传统的公司门禁系统存在的访客管理困难、灵活性差、安全性低等诸多问题,提出一种基于QR二维码识别的访客门禁系统的设计方案。该设计将二维码作为公司访客身份识别的载体,访客通过在摄像头下扫描访客持有的二维码即可打开对应的门锁,实现了二维码、访客和公司门禁的分布式管理。本设计选择STM32F103RCT6单片机作为主控模块,硬件部分主要包括驱动模块、摄像头模块、按键模块、Wi-Fi模块和显示模块。通过多次实际测试,该系统工作稳定,具备实用性、便捷性和安全性等诸多方面的优势。

With the continuous development of Internet of Things technology, the update and upgrade of the access control system has become an inevitable trend. Aiming at the problems of traditional company access control system, such as visitor management difficulty, poor flexibility and low security, a design scheme of visitor access control system based on QR code recognition is proposed. The design uses QR code as the carrier of the company s visitor identification. The visitor can open the corresponding door lock by scanning QR code under the camera, realizing the distributed management of QR, the visitor and the company access control. This design selects STM32F103RCT6 microcontroller as the main control module. The hardware part mainly includes the drive module, camera module, key module, WIFI module and display module. Through many practical tests, the system works stably and has many advantages in practicality, such as convenience and safety.
