When in use, when a person comes in from the outside, under the action of the first infrared sensor, when someone passes by, the human body will emit infrared heat, and the infrared sensor can detect the change of this heat and judge that someone has passed by. After the first infrared sensor judges that someone has passed by, it feeds back a corresponding signal to the face recognition camera, and the face recognition camera is used to perform face recognition on the person moving in front of the protective door. Once the face is detected, the camera will extract the feature information of the face, including key feature points such as facial contour, eyes, nose, mouth, etc. The extracted face feature information will be compared with the face feature database stored in the system in advance to find a matching face. If the detected face feature matches a certain face feature in the database, the system will confirm the identity of the person. And make corresponding responses, feedback corresponding signals to the screw rod through the face recognition camera, so that the output end of the servo motor is reversed, and the screw rod is driven to rotate by the servo motor, so that the slider connected to the threaded surface of the screw rod moves to the left in the slide groove, and the protective door is driven to move to the left in the door opening during the movement of the slider. During the movement, the roller on the lower surface of the protective door slides in the installation groove, so that the protective door is opened and people can enter. At the same time, if the face recognition enters the personnel information in the warehouse, it can be verified through the password authentication module and the NFC recognition module. After the verification is correct, the protective door can be opened. When the personnel in the building need to go out, under the action of the second infrared sensor, after the personnel are detected, the second infrared sensor directly feeds back the signal to the servo motor, so that the protective door is automatically opened, and the personnel going out does not need to be authenticated again. The security access control, through the setting of multiple first infrared sensors, second infrared sensors and face recognition cameras, can quickly verify the information of the personnel passing through this door and automatically open the protective door. It is highly convenient and achieves the purpose of improving the intelligence level of the security access control. BRIEF DESCRIPTION OF THE DRAWINGS
