DETAILED DESCRIPTION

[0021] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The enumerated embodiments are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] Example 1

[0023] like Figure 1-Figure 3 As shown, this embodiment provides a prison anti-tailgating biometric access control system, including a first access control, a door wall 3, and a main controller. The first access control includes a sliding door 1 and a first door frame 2. The upper and lower ends of the first door frame 2 are respectively provided with slide grooves 5. The upper and lower ends of the sliding door 1 are respectively slidably connected to the slide grooves 5 at the upper and lower ends of the first door frame 2. A groove is opened in the door wall 3, and the upper and lower ends of the groove are respectively provided with electric slide rails 4. The electric slide rails 4 are respectively fixedly installed with electric spring push rods 7. A motor is provided in the electric spring push rod 7, and the motor is electrically connected to the main controller. The pop-up ends of the electric spring push rod 7 are respectively fixedly connected to one side of the upper and lower ends of the sliding door 1. The door wall 3 is used to hide the sliding door. The main controller is used to control the electric spring push rod 7 to make the sliding door 1 slide toward the door wall 3, and fix the sliding door 1 when the sliding door 1 slides to the top. When the main controller controls the motor to cut off power, the electric spring push rod 7 pushes the sliding door 1 to slide out in the opposite direction, so that the sliding door 1 can achieve the effect of quickly closing the door.

[0024] A first camera device and an alarm are provided in the first access control. The first camera device is connected to the main controller by signal, and the alarm is electrically connected to the main controller. The first camera device is located above the first access control to facilitate detection of whether the staff has completely passed through the first access control. The first camera device is used to detect whether a person has passed through the first access control. When the first camera device detects that a person has completely passed through the first access control, it sends a signal to the main controller, and the main controller closes the first access control. When the first camera device detects that at least two people have passed through the first access control, the first camera device sends a signal to the main controller. After receiving the signal, the main controller turns on the alarm to sound an alarm, reminding security personnel to rush over as soon as possible to avoid harm to the staff.

[0025] An electric lock is provided on one side of the first door frame 2, and the electric lock is electrically connected to the main controller. A lock buckle for cooperating with the electric lock is provided on the sliding side of the sliding door 1. When the sliding door 1 slides out in the opposite direction of the door wall 3 and closes, the main controller controls the electric lock to be fixedly connected to the lock buckle on the sliding door, so that the sliding door 1 is in a closed state. When the sliding door 1 is about to slide toward the door wall 3, the main controller controls the electric lock to release the fixed connection with the lock buckle on the sliding door 1.

[0026] A vertical groove 8 is also provided on one side of the first door frame 2, and a buffer portion 9 is provided in the vertical groove 8. The buffer portion 9 is used to buffer the sliding door 1. The buffer portion 9 is used to slow down the sliding speed of the sliding door 1 to prevent the sliding door 1 from rebounding in the opposite direction due to the sliding closing speed being too fast.

[0027] A rubber pad is provided on the sliding side of the sliding door 1, and the rubber pad is used to cushion the sliding door and prevent the sliding door 1 from being damaged due to excessively fast sliding and closing speed.

[0028] A first biometric identification device 6 is provided on the outside of the first door frame 3 at the opening of the sliding door 1. The first biometric identification device 6 is connected to the main controller by signal. The first biometric identification device 6 is a live iris recognition. When the staff member successfully passes the live iris recognition, the first biometric identification device 6 sends a signal to the main controller, and the main controller opens the first access control, thereby improving the accuracy of identity recognition.

[0029] In this embodiment, the staff member passes through the first access control after being successfully identified by the first biometric identity recognition device 6. When the staff member completely passes through the first access control, the main controller controls the sliding door 1 in the first access control to close quickly. At the same time, the first access control is in a closed state through the fixed connection between the electric lock and the lock buckle. When the staff member completely passes through the first access control, the first access control is closed and locked at the first time, effectively preventing the following person from following the staff member through the first access control, and avoiding the possibility of the following person easily passing through the access control.

[0030] Example 2

[0031] Based on the above embodiment, the difference between this embodiment and the above embodiment is:

[0032] like Figure 4-Figure 6 As shown, the second access control includes a second door frame, a rotating shaft 10, and a door panel 11. The rotating shaft 10 is fixedly connected to the second door frame. A plurality of equally spaced door panels 11 are connected to the side of the rotating shaft 10. The space between adjacent door panels 11 only allows one person to enter. An electric buckle is provided at the bottom of the second access control. The electric buckle includes a fixing portion 12 and an electric push rod 15. The bottom of the rotating shaft corresponding to the position where the door panel is connected to the rotating shaft is respectively provided with a card slot 15. The fixing portion 12 is provided next to the card slot 15. A card block 14 is provided on the side of the fixing portion 12 close to the card slot 15. The card block 14 is triangular in shape. The shapes of the card slot 15 and the card block 14 match each other. The telescopic end of the electric push rod 15 is fixedly connected to the opposite side of the fixing part 12 close to the card slot 15. The electric push rod 15 is connected to the main controller through the control circuit. When the electric push rod 15 is extended, the fixing part 12 moves toward the card slot 15 and inserts the card block 14 into the card slot 15. The card block 14 is used to clamp the card slot 15. A second camera device is provided in the second access control, and the second camera device is connected to the main controller signal. The card block 14 in the electric buckle can better clamp the rotation of the rotating shaft 10, so that the second access control is in the closed state.

[0033] The structure and working principle of the second biometric identification device are consistent with those of the first biometric identification device 6, and will not be described in detail here.

[0034] In this embodiment, the staff member is successfully identified by the second biometric identification device and a signal is sent to the main controller. After receiving the signal, the main controller controls the electric push rod 15 of the electric buckle to retract the fixed portion 12. The staff member can then push the door panel 11 to pass through the second access control. The staff member can determine the speed of passing through the second access control by the force with which the door panel 11 is pushed. When the second camera device detects that the door panel 11 is rotating, it sends a signal to the main controller. After receiving the signal, the main controller controls the electric push rod 15 of the electric buckle to extend the fixed portion 12. Because the door panel 11 is pushed at this time, the blocking block 14 is not accurately inserted into the slot 15. However, when the staff member enters the second access control, the shaft 10 will also rotate. Because the slot 15 corresponds to the position where the door panel 11 is connected to the shaft 10, when the staff member completely passes through the second access control, the blocking block 14 is inserted into another slot 15 on the shaft 10, causing the second access control to be closed. By providing a second access control, this embodiment prevents the possibility of a trailing person easily passing through the access control. When a trailing person enters the first access control, the presence of the second access control also provides the staff member with an opportunity to escape.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
