Detailed Description

Please refer to fig. 1 to 3:

the utility model discloses well camera 4 model is lnzee K7, and 5 models of LED lamp are 1W-LED lamp pearl, and 6 models of luminance sensor are APDS-9008 and supple materials 020, and microcontroller 8 model is TMS320F2808 PZA.

The utility model provides an intelligent door lock based on face recognition, including lock body 1, door frame 11, wherein, the front of lock body 1 is inlayed and is had touch-sensitive screen 2, the side of lock body 1 has seted up jack 3, the bottommost of jack 3 is inlayed and is had electro-magnet 10, the upper surface of lock body 1 is inlayed and is had camera 4, the periphery of camera 4 is inlayed and is had LED lamp 5, the upper surface edge of lock body 1 is inlayed and is had luminance sensor 6, the top of lock body 1 is rotated and is connected with apron 7, the inside upper end of lock body 1 is inlayed and is had microcontroller 8, the inside lower extreme of lock body 1 is inlayed; specifically, the touch screen 2 can manually input a password to unlock, or modify or add a human face preset by human face recognition, the jack 3 can be inserted with the bolt 13, when the electromagnet 10 in the jack 3 is powered on, the electromagnet 10 can suck and suck the bolt 13 from the inside of the bolt hole 12 by utilizing electromagnetic force, so as to lock the door, the inclined plane of the lock body 1 can help the camera 4 to shoot the human face, the camera 4 converts the shot human face into an electric signal and sends the electric signal to the microcontroller 8, the microcontroller 8 carries out human face recognition and comparison, when human face shooting is carried out, the brightness sensor 6 can detect the ambient brightness and convert the information into the electric signal and send the electric signal to the microcontroller 8, the microcontroller 8 automatically adjusts the irradiation brightness of the LED lamp 5 according to the information, so that the camera 4 can carry out shooting, the cover plate 7 can carry out the operation without using the camera 4, the camera 4 is covered, so that dust is prevented from falling on the camera 4 to influence the shooting definition of the camera 4;
