Description

Technical Field

[0001] The utility model relates to the field of access control, in particular to a license plate recognition access control device. Background Art

[0002] Access control 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] The current license plate recognition access control system is prone to accidents such as accidental collisions. Since the access control railings are made of aluminum alloy, it is easy to damage vehicles on the one hand, and on the other hand, it is easy to cause damage to the interception rod. The service life of the interception rod is short, which is not conducive to the development of a harmonious society. Utility Model Content

[0006] By adopting the above technical solution, the interceptor bar can tilt forward when encountering an unexpected collision, reducing damage to the vehicle, while also protecting the interceptor bar itself from damage. Since the interceptor bar can move when impacted instead of breaking rigidly, this increases the overall durability and service life of the device.

[0007] Furthermore, a driving mechanism is installed inside the device body, and an output end of the driving mechanism passes through the outer wall of the device body and is connected to the rotating seat, so as to drive the rotating seat to rotate.

[0009] Furthermore, a fixing seat is transversely fixed to the back of the device body, the fixing seat is located below the rotating seat, and the fixing seat is horizontally arranged.

[0010] By adopting the above technical solution, the fixed seat can support the weight of the interception rod, ensure no deformation during long-term use, maintain the functionality and reliability of the access control device, and improve the stability of the interception rod.

[0011] Furthermore, the cotton swab is made of pearl cotton, the cotton swab is detachably connected to the aluminum alloy rod, and the cotton swab can be painted with bright colors.

[0012] By adopting the above technical solution, the cotton swab painted with bright colors improves the visibility of the access control device, enabling the driver to clearly see the interception rod even at a distance or under poor visibility conditions, so as to react in advance and avoid collisions. The pearl cotton material is relatively soft, and even in case of accidental collisions, it can reduce the damage to vehicles and personnel, improving the safety of the access control system.

[0013] Furthermore, the connecting rod and the adapter are fixedly connected by bolts.

[0014] By adopting the above technical solution, a firm connection between the connecting rod and the adapter is ensured. This rigid connection method can withstand large external forces such as wind pressure and vehicle collisions, thus maintaining the stability of the access control system.

[0015] Furthermore, a license plate recognition mechanism is installed at the top of the device main body, and a toolbox is provided on the back of the device main body.

[0016] By adopting the above technical solution, the license plate recognition mechanism located at the top can optimize its viewing angle range, recognize the license plates of passing vehicles more quickly and accurately, thereby improving the vehicle passing efficiency.

[0017] Furthermore, the device main body is fixed by anchor bolts.

[0018] By adopting the above technical solution, the anchor bolts can firmly fix the device main body on a concrete foundation or other types of ground, providing high stability and reducing shaking caused by external forces or wind.

[0019] In summary, the main beneficial effects of the present utility model are as follows:

[0020] 1. By setting a torsion rotating shaft, a connecting rod, and an adapter in the present utility model, the rotating seat rotates horizontally 180 degrees with the connecting rod through the torsion rotating shaft, and the connecting rod is connected to the interception rod through the adapter. When a car accidentally collides with the interception rod, due to the forward impact force, the interception rod will be squeezed forward. Under the action of the torsion rotating shaft, the interception rod is movable, so that the interception rod tilts forward but is not damaged, improving the service life of the interception rod and reducing its fracture frequency. When the car leaves, under the action of the torsion rotating shaft, the interception rod returns to its original state;

[0021] 2. In the present utility model, a cotton swab is sleeved on the outer surface of an aluminum alloy bar, and colors are applied on the cotton swab, which is convenient for the driver to observe. When the vehicle accidentally collides with the intercepting rod, under the action of the cotton swab, the vehicle will not be scratched, and no losses will occur to both parties, which is conducive to reducing contradictions.

Then, the power is turned on. For vehicles that need to be automatically recognized and released, their license plate numbers are entered into the system in advance and corresponding permissions are set. When a vehicle approaches the access control device, the license plate recognition mechanism 3 will start and begin to scan the license plate of the approaching vehicle. If the system recognizes that the license plate belongs to an authorized vehicle, the control module will automatically send an instruction to the driving mechanism, and the driving mechanism will start the rotating seat 5, and then control the interception rod 2 to rotate through the connecting rod 52 and the adapter 6, so that the vehicle can pass. If the vehicle accidentally collides with the interception rod 2, due to the action of the torsion rotating shaft 51, the interception rod 2 can tilt forward to absorb the impact, thus avoiding damage to the vehicle and itself. After the vehicle leaves, the interception rod 2 can return to its original position under the action of the torsion rotating shaft 51.
