Description

Technical Field

[0001] The present invention relates to the technical field of access control, and in particular to intelligent security access control based on the Internet of Things. Background Art

[0002] Access control refers to the prohibition authority of a door, which is a precaution against the door. The "door" here, in a broad sense, includes various passages that can be passed, including doors for people to pass through, doors for vehicles to pass through, etc. Therefore, access control includes vehicle access control. In parking lot management applications, vehicle access control is an important means of vehicle management.

[0003] Today's construction site security measures include access control. In order to improve construction safety, security guards and security access control are used to cooperate with each other to strictly limit the number of people entering the construction site. Traditional construction site access control is only equipped with cameras and facial recognition units, and the camera and other structures are fixed structures, that is, after facial recognition, the gate opens automatically. Therefore, there is a possibility that workers bring in workers without permission or who have not had time to apply for construction certificates in the future. The unauthorized workers have not received professional training and health checks, which makes the personnel at the construction site a greater safety hazard. Traditional facial recognition only has the function of recognizing faces and opening gates, and cannot capture the specific movements of people after facial recognition, resulting in security limitations of today's construction site security access control.

[0004] Based on this, intelligent security access control based on the Internet of Things is proposed. Summary of the invention

[0005] The purpose of the present invention is to propose an intelligent security access control based on the Internet of Things in order to solve the above problems.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-6 , the present invention provides a technical solution:

[0029] The intelligent security access control based on the Internet of Things includes a shell 1, a rod 5 is rotatably connected to the shell 1, an identification terminal 4 is connected to the upper end of the rod 5, a camera and a facial recognition unit are connected to the identification terminal 4, and the identification terminal 4 can follow the entry of personnel and capture the video of the entry of personnel. A baffle 3 is arranged on one side of the shell 1, and the baffle 3 is used to block the personnel. The size of the baffle 3 needs to be adjusted according to the use environment to adapt to different use environments to avoid the situation where personnel climb over the access control. This situation also requires security personnel to observe and eliminate it. A fixing frame 6 is fixedly connected in the shell 1, and a button 2 is connected to the fixing frame 6. The button 2 structure is connected to the identification terminal 4 through a lead wire. Through the button 2 Control the opening and closing of the identification terminal 4 to avoid the identification terminal 4 running for a long time, resulting in the entry of a large amount of irrelevant information, which is inconvenient for subsequent video investigation. The fixed frame 6 is slidably connected with a translation block 9, the fixed frame 6 is connected with a fixed seat 12, the fixed seat 12 is rotatably connected with a rod 3 27, the rod 3 27 is connected with a gear 28, and a torsion spring 34 is connected between the gear 28 and the fixed seat 12. By setting the torsion spring 34 structure, when the baffle 3 rotates, the torsion spring 34 starts to accumulate force. When the personnel enter, the baffle 3 is reset under the action of the torsion spring 34. Since the ratchet 29 can only rotate in one direction after being limited by the U-shaped clip 36, the torsion spring 34 can drive the baffle 3 to reset and rotate;

[0030] A rod 40 is rotatably connected to the fixed seat 12, and a gear 3 41 is connected to the rod 40. The gear 3 41 and the gear 2 28 are meshed with each other. The baffle 3 is fixedly connected to the outside of the rod 40. A connecting block 21 is connected to one side of the translation block 9. The connecting block 21 is connected to the middle position of the rod 22. The rod 22 is rotatably connected to the connecting block 21. A limiting ring 24 is connected to the rod 22. Two limiting rings 24 are provided. The connecting block 21 is provided between the two limiting rings 24. Gear 1 23 is connected to the upper and lower ends of the rod 22. A protrusion 26 is connected to the gear 1 23. The protrusion 26 is only connected to the gear 1 23 located above. A rotating column 43 is connected to the lower end of the rod 15. A groove 20 is provided at the lower end of the rotating column 43. The protrusion 26 and the groove 20 can be connected to each other. A limiting mechanism for limiting the rotation of the identification terminal 4 is connected to the fixed frame 6. A telescopic cylinder 8 is connected to one side of the translation block 9.

[0031] Specifically, Figure 2 As shown, a slide groove 11 is provided on the fixed frame 6, and rollers 10 are rotatably connected to the upper and lower ends of the translation block 9. The roller 10 is in rolling contact with the slide groove 11. By setting the slide groove 11 and the roller 10 structure, the stability of the translation block 9 moving on the fixed frame 6 is improved, so as to achieve the effect of quickly controlling the movement of the connecting frame 15.

[0032] Specifically, Figure 5As shown, a limiting frame 30 is connected to the fixed seat 12, and the rod three 27 and the rod four 40 are both rotatably connected to the limiting frame 30. By setting the limiting frame 30, the limiting of the structure of the rod three 27 and the rod four 40 is completed, ensuring that the gears connected to the two structures can be stably engaged, thereby improving the stability of the structural transmission.

[0033] Specifically, Figure 3 and Figure 4 As shown, a cam 25 is connected to the rod 15, a symmetrical rod 18 is slidably connected to the fixed frame 6, one end of the symmetrical rod 18 is connected to an abutment block 17, the other end of the symmetrical rod 18 is connected to an abutment spring 19, the other end of the abutment spring 19 is connected to the fixed frame 6, and one side of the translation block 9 is also connected to an abutment block 17. The abutment block 17 is set to abut and limit the cam 25, limit the rotation angle of the cam 25, and play a correction role. The two cams 25 limit the positions of the protrusion 26 and the groove 20 respectively, to ensure that when the two structures are docked, the structures can be stably connected.

[0034] Specifically, Figure 2 As shown, the telescopic cylinder 8 is connected to a cylinder frame 7, and the cylinder frame 7 is connected to the fixed frame 6 by bolts. By providing the cylinder frame 7, the firmness of the connection of the telescopic cylinder 8 is improved.

[0035] Specifically, Figure 4 and Figure 5 As shown, the limiting mechanism includes a U-shaped clamp 36, the inner side of the U-shaped clamp 36 is connected with a reverse tooth 37, and one side of the gear 28 is connected with a ratchet 29. When the reverse tooth 37 is docked with the ratchet 29, it can limit the rotation of the ratchet 29 on one side, and when the ratchet 29 rotates in the opposite direction to reset, the rotation of the ratchet 29 structure is not affected. The fixed frame 6 is connected with a fixed seat 2 13, and the fixed seat 2 13 is a fixed structure. The firmness of the connection with the frame 14 is improved by setting the fixed seat 2 13. The fixed seat 2 13 is connected to the frame 14, and the frame 14 is slidably connected with a translation frame 31. The translation frame 31 consists of three straight rod structures, and the U-shaped clamp 36 is connected to the translation frame 31.

[0036] Specifically, Figure 4 and Figure 5As shown, a toggle rod 35 is connected to the translation frame 31, a deflection shaft 32 is connected to the frame 14, a deflection rod 33 is rotatably connected to the deflection shaft 32, a toggle slot 44 is provided on the deflection rod 33, the toggle rod 35 is slidably connected to the toggle slot 44, a switching rod 42 is connected to the deflection rod 33, a spring rod 38 is connected to the frame 14, a switching spring 39 is connected between the spring rod 38 and the switching rod 42, and by setting the switching spring 39 structure, the deflection rod 33 can only be in the left and right gears when not affected by external forces. The two gears represent limiting and canceling the limiting of the ratchet 29, respectively, to stabilize the transmission between the structures, and when the U-shaped clamp 36 limits the ratchet 29, due to the inverted tooth 37 structure, the ratchet 29 can be easily limited, and there is no need for external force to push the U-shaped clamp 36 and the ratchet 29 structure to be closely connected, thereby improving the stability of the limit.

[0037] Specifically, Figure 3 , Figure 4 and Figure 5 As shown, the telescopic end of the telescopic cylinder 8 is connected to a connecting frame 15, and a toggle claw 16 is connected to the connecting frame 15. The toggle claw 16 is arranged on one side of the deflection rod 33. The purpose of setting the toggle claw 16 to toggle the deflection rod 33 to deflect, rather than relying on the connecting frame 15 to be directly connected to the deflection rod 33, is to improve the timeliness of the limit, that is, when the toggle claw 16 is used to push the deflection rod 33 to deflect through the middle position between the two gears, the deflection rod 33 can move quickly to the next gear under the action of the switching spring 39, thereby avoiding the slow extension and retraction speed of the telescopic cylinder 8, resulting in untimely limitation of the baffle 3, that is, the timeliness of the limitation of the baffle 3 can be further improved under the premise of rapid extension and retraction of the telescopic cylinder 8.

[0038] In summary, the smart security access control based on the Internet of Things provided in this embodiment, when an internal personnel needs to enter the construction site through the access control, firstly needs to press the button 2 structure, and the identification terminal 4 is turned on. At this time, the camera on the identification terminal 4 can recognize the face of the person, and after judging that the person is an internal person, the telescopic cylinder 8 starts to extend;

[0039] The connecting frame 15 and the toggle claw 16 are driven to move by the telescopic cylinder 8, and the toggle claw 16 is used to toggle the deflection rod 33 to deflect. Since a switching rod 42 structure is connected to one side of the deflection rod 33, the switching rod 42 and the switching spring 39 are connected to each other, so that the deflection rod 33 can be immediately driven to switch between the left and right gears when the deflection rod 33 is toggled. The toggle groove 44 on the deflection rod 33 is used to drive the toggle rod 35 to move, thereby driving the translation frame 31 to slide on the frame 14. At this time, the U-shaped clip 36 and the ratchet 29 are separated from each other. When the U-shaped clip 36 and the ratchet 29 are matched, the ratchet 29 cannot rotate. Therefore, when the two structures are separated, the ratchet 29 is not restricted and can rotate at will.

[0040] The telescopic cylinder 8 is used to drive the translation block 9 to slide on the fixed frame 6. At this time, the translation block 9 drives the rod 22 to move to the side of the rod 3 27. When it moves to the maximum distance, the convex block 26 structure connected to the upper end of the rod 22 can be connected with the groove 20 on the rotating column 43. At this time, the personnel who meet the entry standards can push the baffle 3 to move. When the baffle 3 is pushed, the rod 40 rotates, and the gear 3 41 and the gear 2 28 are meshed with each other, so the rod 3 27 can be driven to rotate at the same time. The gear 2 28 and the gear 1 23 are meshed with each other. At this time, the rod 22 can rotate synchronously, and the rod 2 22 is used to drive the identification terminal 4 to rotate. At this time, as the personnel push the baffle 3 to rotate, the identification terminal 4 can rotate synchronously, ensuring that the identification terminal 4 can follow the movement of the personnel for mobile capture, avoiding the situation where the internal personnel carry the external personnel to the inside. When an internal person passes through the security access control, the person's face needs to face the identification terminal 4 to avoid the identification terminal 4 being unable to determine whether it is an internal person, causing the telescopic cylinder 8 to contract, so that the U-shaped clamp 36 is reset, and the operation of locking the baffle 3 to rotate is completed to prevent outsiders from entering the construction site. When the baffle 3 rotates to the maximum angle, the access control is in the open stage, and the internal person restricts the baffle 3 from rebounding. At this time, outsiders can enter the construction site. In order to eliminate this problem, the identification terminal 4 is connected to the Internet of Things, which can alarm for abnormalities when the baffle 3 is opened to the maximum angle and then continues to be opened. The abnormal alarm also includes the reverse opening of the baffle 3. At this time, the security personnel need to conduct a safety inspection of the access control to prevent outsiders from entering the construction site. Each time the identification terminal 4 is turned on, the personnel video information recorded by the camera will be uploaded to the Internet of Things, which is convenient for subsequent investigation of the personnel passing the access control information;

[0041] Through this security access control, the information of people passing through the access control can be accurately obtained. In the event of an abnormal access control situation, the opening structure can be quickly locked and an alarm signal can be issued. Security personnel and IoT online personnel can be cooperated to conduct inspections and eliminate safety hazards, greatly improving the construction safety of the construction site.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
