[0034] The inventor of this application proposes an intelligent anti-tailgating access control device, referring to Figure 1-Figure 5 , Figure 1 A schematic diagram of the three-dimensional structure of an intelligent anti-tailgating access control device provided in an embodiment of the present application, Figure 2 A top view of an intelligent anti-tailgating access control device provided in an embodiment of the present application, Figure 3 A schematic diagram of component connections of an intelligent anti-tailgating access control device provided in an embodiment of the present application, Figure 4 A front view of an intelligent anti-tailgating access control device provided in an embodiment of the present application, Figure 5 for Figure 4 Schematic diagram of the structure at a in the figure.

[0035] Reference Figure 1-Figure 5 The access control device includes an access control room 1, an identification device 2, an access control switch device 3 and a pressure rod 4. The access control room 1 is provided with an exit 5; the identification device 2 and the access control switch device 3 are arranged at the entrance of the access control room 1; the access control switch device 3 includes an access control shaft 31 with a plurality of grooves 311; the pressure rod 4 includes: a sleeve 41, a spring 42, a plug 43 and an electric push rod 44, the sleeve 41 and the plug 43 are nested and retractable, the spring 42 is arranged in the sleeve 41, the plug 43 is elastically connected to the spring 42, and the back cover of the sleeve 41 is installed on the top of the electric push rod 44; the plug 43 can be embedded in the groove 311.

[0036] Among them, the identification device 2 can adopt biometric identification technology, such as fingerprint identification, facial recognition, iris recognition, etc., or card identification technology, such as IC card, RFID card, etc., to identify the identity of a legitimate user; the access control shaft 31 is the core part of the access control switch device 3, with a plurality of grooves 311, which are used to engage with the insertion rod 43 of the pressure rod 4. When the insertion rod 43 is embedded in the groove 311, the access control shaft 31 is locked. When the insertion rod 43 is withdrawn from the groove 311, the access control shaft 31 can rotate, and the access control shaft 31 The control can be realized by the motor 7 or human power, ensuring that after receiving the door opening signal from the legitimate user, the electric push rod 44 of the pressure rod 4 can be retracted to pull the plug rod 43 out of the groove 311, ensuring that the access control shaft 31 can rotate; the sleeve 41 of the pressure rod 4 and the plug rod 43 are nested and retractable, and the plug rod 43 can automatically pop out or retract under the action of the spring 42. When the plug rod 43 is retracted, it is separated from the groove 311; the electric push rod 44 is installed on the back cover of the sleeve 41 to control the extension and retraction of the plug rod 43. When receiving the door opening signal, the electric push rod 44 pushes the plug rod 43 to retract, so that the access control shaft 31 can rotate.

[0037] In the specific working process, three rows of plug rods 43 can be evenly arranged outside the access control shaft 31, and the distribution angle of the plug rods 43 on the access control shaft 31 is 120 degrees. Correspondingly, three grooves 311 are evenly arranged on the outer periphery of the access control shaft 31. When the access control switch device 3 is in the closed state, the plug rod 43 of the pressure rod 4 is embedded in the groove 311, and the access control shaft 31 is locked at this time. When the pressure rod 4 receives the door opening signal from the legitimate user, the electric push rod 44 of the pressure rod 4 contracts to pull the plug rod 43 out of the groove 311, and the access control shaft 31 can rotate at this time. When the plug rod 43 is pulled out of the groove 311, when the identification device 2 receives the rotation signal of the access control shaft 31, the electric push rod 44 returns to its original state. Of course, the identification device 2 can also be set to contract. After 1 to 2 seconds, the electric push rod 44 of the pressure rod 4 returns to its original state. At this time, since the end of the insertion rod 43 is located on the surface of the access control shaft 31, the sleeve 41 and the insertion rod 43 make the spring 42 in a compressed state, and the access control shaft 31 can continue to rotate. When the access control shaft 31 is pushed by an external force, so that the next groove 311 rotates to the position of the insertion rod 43, the insertion rod 43 automatically pops out and embeds into the groove 311 under the action of the spring 42. At this time, the access control shaft 31 cannot rotate, thereby achieving the effect of anti-tailgating.

[0038] Continue to refer to Figure 1-Figure 5The identification device 2 includes an identification module 21 and a controller 22. The identification module 21 is electrically connected to the controller 22. The driving mechanism of the electric push rod 44 is electrically connected to the controller 22. The controller 22 can accurately control the extension and retraction action of the electric push rod 44. When the access control needs to be opened or closed, the controller 22 will send corresponding instructions to the electric push rod 44, thereby realizing precise control of the access control.

[0039] When the user approaches the access control room, the identification module 21 will start working and collect the user's identity information. The identification module 21 will compare the collected information with the preset legitimate user information to verify the user's identity. Once the identification module 21 completes the comparison of the identity information and verifies the user's identity, it will transmit the verification result such as "verification successful" or "verification failed" to the controller 22 through an electrical connection. If the verification result is "verification successful", the controller 22 will send a door opening signal to the electric push rod 44. After the electric push rod 44 retracts, the plug 43 is pulled out of the groove 311, allowing the user to pass through the access control room. If the verification result is "verification failed", the controller 22 will prevent the electric push rod 44 from retracting and deny the user entry.

[0040] Continue to refer to Figure 1-Figure 5 The access control switch device 3 also includes: an access control frame 32 and an access control railing 33; wherein the access control frame 32 is arranged at the entrance of the access control room 1, and provides a stable supporting structure for the access control shaft 31 and the access control railing 33, the access control shaft 31 is vertically arranged on the access control frame 32, and a plurality of the access control railings 33 are equidistantly arranged on the access control shaft 31, and the pressure rod 4 is transmission-connected to the access control shaft 31.

[0041] Continue to refer to Figure 1-Figure 5 The access control switch device 3 also includes an anti-drilling bar 34, which is arranged on the access control frame 32, and the anti-drilling bar 34 is staggered with the access control railing 33, the purpose of which is to prevent someone from trying to drill through the gap between the access control railings 33, thereby increasing the security of the access control system.

[0042] Optionally, continue to refer to Figure 1-Figure 5 The access control device further includes a lock 6, wherein the lock 6 is disposed at one end of the door panel of the exit 5 and is used to control the closing state of the exit 5. When a person passes through the access control switch device 3 and enters the access control room 1, the access control switch device 3 is closed, the lock 6 is opened, and the person passes through.

[0043] Specifically, the controller 22 is electrically connected to the motor 7. When a person passes the identity recognition by the identification module 21, the motor 7 controls the access control shaft 31 to rotate, the insertion rod 43 of the pressure rod 4 pops out of the groove 311, and the access control railing 33 can be pushed. On the contrary, if the person fails to pass the identity recognition, the access control railing 33 cannot be pushed.

[0044] Optionally, continue to refer to Figure 1-Figure 5 The exit 5 is also provided with an alarm button 8. When a person is in danger, the alarm button 8 can be triggered to quickly alarm, seek help or alert security personnel.
