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
