Door control identity recognition system and method based on mobile terminal

The invention discloses a door control identity recognition system based on a mobile terminal. The system comprises a door control identity recognition device and the mobile terminal. A door control identity recognition method based on the mobile terminal comprises the following steps: registering a unique identity of the mobile terminal to the door control identity recognition device when the mobile terminal is used for the first time, and periodically sending a wireless radio message by the door control identity recognition device; detecting the wireless radio message of the door control identity recognition device by the mobile terminal according to a set strategy, initiating a door opening request after detecting the wireless radio message of the door control identity recognition device, receiving the door opening request of the mobile terminal by the door control identity recognition device, performing identity-based permission authentication on the door opening request, and performing a corresponding door control operation. According to the system and the method, a user can use the door control system by only carrying the mobile terminal without card swiping or means such as biological identity recognition, and also does not need to interact with the door control system in a physical contact manner, so that the door control system can be more conveniently used by the user; at the aspect of the cost, a large amount of card expenses are saved in comparison with card identification systems.
