Bluetooth detection based access control system with selectable direction

The invention discloses a bluetooth detection based access control system. A modern control technology is combined with the system, and the system can be applied to safety access control. In the provided system, a central controller is taken as the core; the data obtained by a bluetooth detection module after detection is compared with data in the data base, the access control is controlled according to the results of comparison; and at the same time, whether the bluetooth module is in the inner side or outer side of the door is judged. Through an operation interface, the data in the central controller can be processed, the multi-mode control of the access control system can be achieved, and the bluetooth detection mode can also be set. The system takes the detected bluetooth account as the basis, the physical address of bluetooth is unique, the bluetooth data can be transmitted through wireless network, and the safety and convenience are both improved.
