Abstract: Considering that Internet of Things has been widely used for community management, an elevator entrance guard control system based on STM32 MCU is designed by applying embedding technology and taking advantage of the fast-developing internet platform. On the basis of the elevator control system, the entrance guard control system adopts entrance guard control technology and image recognizing techniques and RFID technology, realizing functions such as online monitoring and management of application and defending tagging along. The system applies STM32F407 as master control chip, is equipped with μC/OS-II real-time operation system and realizes communication with the server of smart community comprehensive management platform through connection between Ethernet and router. A test is performed finally which proves that the system runs in a stable manner and expects extensive use.

Key words: Internet of things, defending tagging along, entrance guard system, elevator control

摘要： 针对物联网技术在社区管理中的广泛应用，采用嵌入式技术，利用现代高速发展的网络平台设计了一种基于STM32单片机的电梯门禁控制系统。控制系统在电梯控制系统的基础上，结合门禁控制技术、图像识别技术和RFID技术，实现电梯的联网监控、人员使用管理和防尾随等功能。控制系统采用STM32F407作为主控制芯片，搭载μC/OS-II实时操作系统，通过以太网与路由器连接，实现与智慧社区综合管理平台服务器的通讯。通过测试表明，该系统运行稳定，具有广泛的应用前景。
