Intelligent access control system based on two dimensional code technology and control method thereof

The invention provides an intelligent access control system based on a two dimensional code technology and a control method thereof. The intelligent access control system comprises a display screen, an electronic lock, an access controller, a server, a network transmission module and a mobile terminal, the access controller is in communication with the server through the network transmission module, the unique serial number is obtained and displayed on the display screen in a mode of a two dimensional code, the two dimensional code is scanned through the mobile terminal, the serial number corresponding to the two dimensional code is transmitted to the server, user identification and authority information are verified through the server, and the access controller is made to be acted correspondingly. According to the access control system, the unique two dimensional code serves as an identity certificate, the safety is high, various sensor modules are not needed, an intelligent card does not need to be managed, the cost can be reduced, and the user experience is promoted.
