[0024] Please refer to Figure 1 - Figure 3 Figure 1 - Figure 3 , on one side of the function device 3, there is an ID card reader 32. Inside the function device 3, at the position corresponding to the ID card reader 32, there is a placement cavity 321. The placement cavity 321 is adapted to the ID card reader 32. On one side of the ID card reader 32 located inside the placement cavity 321, an identification module 322 is fixedly installed. On one side of the ID card reader 32, an inductance coil 323 is fixedly installed outside the outer circle of the identification module 322.
[0025] Please refer to Figure 1 - Figure 5 Figure 1 - Figure 5 , above the ID card reader 32 on one side of the function device 3, there is a camera 33. Inside the function device 3, a circuit breaker A34 and a circuit breaker B35 are symmetrically arranged. The identification module 322 is electrically connected to the circuit breaker A34. The circuit breaker A34 is electrically connected to the electromagnet A22. The camera 33 is electrically connected to the circuit breaker B35. The circuit breaker B35 is electrically connected to the electromagnet B23 and the electromagnet C24. The identification module 322 is electrically connected to the alarm 4. The camera 33 is electrically connected to the display screen 31.
[0026] The user places the ID card at the ID card reader 32. After being identified by the identification module 322, if the identification is passed, the circuit breaker A34 is controlled to cut off the power supply to the electromagnet A22, so that the electromagnet A22 loses its magnetism and the opposite-sex attraction with the iron block A121 is disconnected. Then the user can push the door to pass through this access control. When someone wants to attack the identification module 322 to make the identification module 322 ineffective and pass through this access control, the inductance coil 323 will prevent external electromagnetic signals from interfering with the identification module 322. At the same time, inside the function device 3, the ID card reader 32, the circuit breaker A34, and the electromagnet A22 of this access control system are disconnected, and an electrical signal is sent to the inside of the alarm 4 to activate the alarm 4, so that the alarm 4 emits an alarm sound to remind the management personnel to check in time. The camera 33, the circuit breaker B35, the iron block B122, and the iron block C123 access control system are activated. After activation, the circuit breaker B35 supplies power to the electromagnet B23 and the electromagnet C24, so that the electromagnet B23 and the electromagnet C24 generate opposite-sex attraction with the iron block B122 and the iron block C123. When the subsequent user passes through this access control, the camera 33 will perform face recognition and display the recognized face on the display screen 31. When the display screen 31 recognizes that the face matches the face in the background system, an electrical signal is sent to the circuit breaker B35, so that the circuit breaker B35 cuts off the power supply to the electromagnet B23 and the electromagnet C24, so that the electromagnet B23 and the electromagnet C24 lose their magnetism and the magnetic attraction with the iron block B122 and the iron block C123 is disconnected, enabling the user to pass through this access control normally.
[0027] Working principle: The user places the ID card at the ID card reader 32. After being recognized by the recognition module 322, if the recognition is passed, the circuit breaker A34 controls to cut off the power supply of the electromagnetic block A22, so that the electromagnetic block A22 loses its magnetism and the attraction between the opposite sexes with the iron block A121 is disconnected. Then the user can push the door to pass through this access control. When someone wants to attack the recognition module 322 to make it ineffective, the inductance coil 323 protects the recognition module 322 to avoid damage to the components of the recognition module 322. The inductance coil 323 will prevent external electromagnetic signals from interfering with the recognition module 322. At the same time, inside the function device 3, the access control system of the ID card reader 32, the circuit breaker A34, and the electromagnetic block A22 is disconnected, and an electrical signal is sent to the inside of the alarm 4 to activate the alarm 4, so that the alarm 4 emits an alarm sound to remind the management staff to check in time;
[0028] Enable the access control system of the camera 33, the circuit breaker B35, the iron block B122 and the iron block C123. After enabling, the circuit breaker B35 supplies power to the electromagnetic block B23 and the electromagnetic block C24, so that the electromagnetic block B23 and the electromagnetic block C24 generate attraction between the opposite sexes with the iron block B122 and the iron block C123. When the subsequent user passes through this access control, the camera 33 will perform face recognition and display the recognized face through the display screen 31. When the face recognized by the display screen 31 matches the face in the background system, an electrical signal is sent to the circuit breaker B35, so that the circuit breaker B35 cuts off the power supply to the electromagnetic block B23 and the electromagnetic block C24, so that the electromagnetic block B23 and the electromagnetic block C24 lose their magnetism and the magnetic attraction with the iron block B122 and the iron block C123 is disconnected, enabling the user to pass through this access control normally.
