(21) Compare the face, fingerprint and IC card data stored in it. When the comparison fails, it means that the recognition fails. At this time, it sends the signal to the central processing unit (22), and controls the alarm device (7) through it. An alarm is issued, and when the comparison is successful, it sends a signal to the central processing unit (22), and the central processing unit (22) controls the electric control lock (33) to open to achieve the unlocking effect; C: The face picture collected by the face acquisition module (9) is also transmitted to the monitoring picture cloud storage module (26) through the wireless data transmission module (25), and the information stored in the monitoring picture cloud storage module (26) is related to the local area network (26). 30) Realize networking, when the feature comparison module (20) is successfully compared, it sends a signal to the central processing unit (22), and the central processing unit (22) controls the display screen (13) to display the two-dimensional code (23) , the user can scan the two-dimensional code (23) through the mobile phone terminal (24) to log in to the local area network (30), and through the local area network (30) to view the monitoring screen in the cloud storage module (26) of the monitoring screen in real time, when the user When watching a stranger performing an access control collection operation, an instruction may be sent to the wireless signal receiving module (28) through the mobile phone terminal (24), and the instruction may be sent to the central processing unit (22) through the wireless signal receiving module (28), and the The central processing unit (22) controls the locking module (29) to lock the face acquisition module (9), the fingerprint acquisition module (5) and the IC card reader (2), so as to prevent strangers from opening the door, so as to achieve the security effect .
