[0034] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0035] like Figure 1-4 As shown: A face recognition security door lock includes an outer panel 1, the inner side of the outer panel 1 is connected to a clutch on a lock body 3 through a control square shaft 2, the other end of the control square shaft 2 is connected to an inner panel in the room, and the inner panel is located on the other side of the lock body 3.

[0036] A central processing module, a face image acquisition module, a human-computer interaction module, a switch module, a power module, an alarm module, and a door lock control module are provided on the outer panel 1. The central processing module is connected to the face image acquisition module, the human-computer interaction module, the switch module, the alarm module, and the door lock control module, and the power module is connected to the central processing module through the switch module.

[0037] The central processing module includes a central processing unit 4 and a face recognition module connected to the central processing unit 4 , and the central processing unit 4 is installed on the outer panel 1 .

[0038] The facial image acquisition module includes an infrared camera module and an information storage module. The infrared camera module includes an infrared camera 8. The infrared camera 8 is installed in a slide groove opened on the outside of the outer handle 7, and a flush transparent protective cover is provided in the slide groove on the outer handle 7. The transparent protective cover adopts explosion-proof glass, which can realize its protection work without affecting the operation of the infrared camera 8. The outer handle 7 is fixed on the outer panel 1.

[0039] The human-computer interaction module includes a contact switch module and a key control module. The key control module includes a button control panel 5. The button control panel 5 is connected to the central processing unit 4. The button control panel 5 is used to actively control the face recognition registration process, and can control the door lock state by inputting instructions to the central processing unit 4.

[0040] The contact switch module includes a contact switch 14, which is located on the inner side of the outer handle 7. The contact switch 14 is connected to the micro motor 13, and the micro motor 13 is fixed in the outer panel 1. The contact switch 14 is regionally arranged on the inner side of the outer handle 7. The contact switches 14 at the upper and lower positions of the inner side of the outer handle 7 cause the micro motor 13 to rotate forward and reverse, thereby controlling the position movement direction of the infrared camera 8.

[0041] The output end of the micro motor 13 is connected to the transmission belt 12 through the tensioning wheel 10. The transmission belt 12 is located in a slide groove opened on the outside of the outer handle 7. The transmission belt 12 and the inner side of the outer handle 7 are fitted together through the auxiliary wheel 11 to avoid friction of the transmission belt 12 and ensure that the transmission belt 12 works normally. The infrared camera 8 is fixedly connected to the transmission belt 12. The infrared camera 8 is a sliding structure in the slide groove through the transmission belt 12, which ensures the stable and safe movement of the infrared camera 8.

[0042] The door lock control module includes a door lock control motor, which is connected to the control shaft 2, and the door lock control motor is connected to the central processor 4 to automatically control the door lock. The door lock control module also includes a mechanical rotary switch 6, which is connected to the control shaft 2, and the mechanical rotary switch 6 is controlled by a key to actively control the door opening.

[0043] The LED lamp 9 is installed on the inner side of the outer panel 1. The LED lamp 9 is connected to the power module through the contact switch 14. Touching the contact switch 14 can turn on the LED lamp 9, so that the LED lamp 9 can be used for lighting at any time.

[0044] When using the door lock, firstly, it is necessary to ensure normal power-on, then operate the button control panel 5, send a face information entry instruction to the central processor 4, and the central processor 4 controls the infrared camera module in the face image acquisition module, collects the corresponding face information through the infrared camera 8, and stores the face information in the information storage module, thus completing the face information entry work;

[0045] Afterwards, the user holds the outer handle 7 and touches the contact switch 14 on the outer handle 7, and the LED light 9 on the outer panel 1 lights up, and the light is directed toward the door panel. The light will not directly illuminate the user, which can increase the brightness while preventing the user's facial expression from changing due to the light, thereby preventing the face recognition from being affected.

[0046] At the same time, the user will hold the outer handle 7 at different positions according to their height. For example, an adult is relatively tall and usually holds the upper position of the outer handle 7 when opening the door. When holding the outer handle 7, the user stands relatively close to the door handle, and the contact switch 14 on the upper part of the outer handle 7 controls the micro motor 13 to start. The micro motor 13 rotates the transmission belt 12 upward through the tensioning wheel 10, and the infrared camera 8 can move upward in the groove on the outer handle 7. If the user is very young, he holds the lower position of the outer handle 7 when opening the door, so that the infrared camera 8 will move downward, so that the infrared camera 8 can complete the face collection work at a more comprehensive angle;

[0047] After the infrared camera 8 completes the facial image acquisition, the facial image acquisition module transmits the information to the central processing module, and the central processing unit 4 instructs the facial recognition module to perform information recognition. If the information does not match, the central processing unit 4 controls the alarm module to issue a warning. If the information matches, the central processing unit 4 starts the door lock control module including the door lock control motor, and controls the rotation of the square shaft 2 to open the lock body 3 and complete the door opening operation.
