Description

Technical Field

[0001] The present invention relates to the technical field of access control management data acquisition, and specifically to an image acquisition system for building access control management. Background Art

[0002] Access control refers to the prohibited permission of a "door", which is the guard against the "door". Here, the "door" generally includes various passages that can be passed through, including doors for people to pass through, doors for vehicles to pass through, etc. Most modern access control devices use an access control security management system at the entrance and exit. The access control security management system at the entrance and exit is a new type of modern security management system. Common access control systems include: password access control system, non-contact card access control system, fingerprint iris palm biometric recognition access control system, and face recognition access control and attendance system, etc. The access control system has developed rapidly in recent years and is widely used in management control systems.

[0003] However, the current image acquisition system mainly collects images through a collection camera, thereby driving whether the turnstile is opened or closed. However, it is found in actual use that during the process of entering and leaving a general building door, there are different passenger flows at different time periods, and the camera of the image acquisition system has been exposed outside. Therefore, when the passenger flow is small, the camera basically does not work, and the camera that does not work and is exposed outside is prone to dust accumulation, resulting in unclear captured images. Thus, an image acquisition system for building access control management that can be automatically opened when needed is proposed. Summary of the Invention

A connecting rod 19 is movably arranged on the surface of the second turntable 17. A sponge eraser 21 is arranged at the end of the connecting rod 19, and the sponge eraser 21 is attached to the bottom of the image acquisition display screen 7. By arranging the storage component and the cleaning component, the storage component can store and protect the image acquisition display screen. And when the image acquisition display screen needs to be used, first start the cleaning component to clean it, and then flip it through the storage component, ensuring that the surface of the image acquisition display screen is clean every time it is collected.

[0027] Please refer to Figures 1-5 , in the specific implementation, a pair of gates 4 are movably arranged on the opposite surfaces of the turnstile 1. The bottom of the turnstile 1 is fixedly arranged on the surface of the foundation 2, and a pressing plate 3 is movably inserted on the surface of the foundation 2. The end of the pressing plate 3 is installed with a telescopic rod 32. The telescopic rod 32 is fixedly arranged in the inner cavity of the foundation 2. A pull rod 33 is fixedly arranged on the side wall of the pressing plate 3. The end of the pull rod 33 is provided with a vertical rod 26, and the vertical rod 26 movably penetrates through the side wall of the turnstile 1. The pressing plate 3 on the surface of the turnstile 1 is stepped on by the detected person, thereby driving the pressing plate 3 to move downward at this time, and then driving the telescopic rod 32 at the bottom to move downward synchronously. The telescopic rod 32 is convenient for later resetting, and finally drives the vertical rod 26 to start moving downward through the pull rod 33.

[0028] Please refer to Figures 1-5, in this embodiment, a connecting bracket 25 is fixedly arranged at the end of the vertical rod 26.

And the first chute 28 is a vertical chute, and the second chute 29 is an inclined chute. During the process of the separation between the guide wheel 24 and the guide baffle 23, at this time, the limit slider 30 at the bottom of the vertical rod 26 always separates along the first chute 28. When the guide wheel 24 is completely separated from the guide baffle 23, at this time, the limit slider 30 moves to the lowest end of the first chute 28. As the vertical rod 26 continues to move downward, at this time, the limit slider 30 slides along the second chute 29, pushing the flat plate 27 and the cross bar 13 on the surface to start moving leftward.

[0029] Please refer to Figures 1-5 , the second rotating shaft 15 is movably arranged on the side wall of the turnstile 1.

The first rotating shaft 8 rotates, driving the first torsion spring 35 inside the first rotating shaft 8 to rotate, which is convenient for later reset.

[0030] Please refer to Figures 1-5 , a second limiting seat 34 is movably arranged on the side wall of the vertical rod 26, and the second limiting seat 34 is arranged inside the turnstile 1. A first limiting seat 14 is movably arranged on the side wall of the cross bar 13, and the first limiting seat 14 is arranged on the inner side wall of the turnstile 1. The first limiting seat 14 and the second limiting seat 34 ensure that the cross bar 13 and the vertical rod 26 can only move along the expected track.

[0031] It should be noted that the present invention is an image acquisition system for building access control management. Each component is a common standard component or a component known to those skilled in the art. Its structure and principle can be known by those skilled in the art through technical manuals or by conventional experimental methods.

[0032] Working principle:

[0033] When image acquisition is required, first, the user walks to the surface of the turnstile 1, and at this time, the pressing plate 3 on the surface of the turnstile 1 is stepped on by the detector, driving the pressing plate 3 to move downward at this time, and then driving the telescopic rod 32 at the bottom to move downward synchronously. The telescopic rod 32 is convenient for later reset, and finally drives the vertical rod 26 to start moving downward through the pull rod 33.

[0034] When the vertical rod 26 moves downward, it drives the guide wheel 24 at the end to start moving downward at this time. When the guide wheel 24 moves downward at this time, it squeezes the guide baffle 23 movably arranged on the surface to start rotating under the limit of the second rotating shaft 15, and the internal second torsion spring 16 starts to rotate, which is convenient for later reset, and finally separates the guide wheel 24 from the guide baffle 23.

[0035] During the rotation of the second rotating shaft 15, the turntable 17 fixedly connected to the surface starts to rotate. Through the guide protrusion 18 on the surface of the turntable 17 sliding in the strip groove 20, the connecting rod 19 provided with the strip groove 20 is pushed to move towards the center, and finally the sponge wipe 21 on the surface of the connecting rod 19 is pushed to move towards the center to complete the wiping of the image acquisition display screen 7.

[0036] During the separation of the guide wheel 24 from the guide baffle 23, the limit slider 30 at the bottom of the vertical rod 26 always separates along the first sliding groove 28. When the guide wheel 24 is completely separated from the guide baffle 23, the limit slider 30 moves to the lowest end of the first sliding groove 28. As the vertical rod 26 continues to move downward, the limit slider 30 slides along the second sliding groove 29, pushing the flat plate 27 and the cross bar 13 on the surface to start moving to the left.

[0037] The cross bar 13 moves to the left, pulling the connecting cam 9 on the surface to start rotating through the swing rod 12, and the rotation of the connecting cam 9 drives the first rotating shaft 8 at the center to start rotating, and then drives the swing arm bracket 6 and the image acquisition display screen 7 to start rotating, so as to facilitate the movement of the image acquisition display screen 7 to the working position, and the first torsion spring 35 inside the first rotating shaft 8 rotates, which is convenient for later reset.
