Description

Technical Field

[0001] The present invention relates to the field of unmanned gates, and in particular to an unmanned gate for rapid release based on Internet of Things control. Background Art

[0002] A barrier gate is a channel management device used to control the entry and exit of vehicles. It is generally installed at the vehicle entrance and exit of a building. Currently, the Internet of Things control system is widely used. In order to reduce the cost of manual supervision, many barrier gates now use the Internet of Things to control unattended barriers. Unattended barriers can autonomously identify license plates and determine the time when vehicles enter and exit. The control is intelligent and convenient.

[0003] Chinese patent CN202011134530.7 discloses a fast-release gate and a passage gate, including a machine base, on which a main motor is fixed, and the main motor drives a gate rod frame to swing up and down in a vertical direction, and the gate rod frame is arranged on a side of the machine base away from the direction of vehicle travel, and a gate rod is rotatably arranged on the gate rod frame, and when the gate rod frame swings upward, the gate rod is driven by a driving device to swing around the gate rod frame along the direction of vehicle travel. The passage gate has the advantage of not affecting the normal passage of vehicles.

[0004] Some of the existing unmanned barriers are very mechanical in identifying and releasing vehicles, and cannot determine the peak hours of vehicle entry and exit. For many public places, there are morning and evening commuting peaks and weekend traffic peaks, and the lifting speed of many barriers is fixed. It is not convenient to automatically adjust the lifting speed according to the frequency changes of vehicle entry and exit, which is not conducive to the rapid release of vehicles during peak vehicle entry and exit periods. In addition, some unmanned barriers have a certain range for vehicle identification. When the vehicle is stopped at a close distance in front of the gate, it is not conducive to identifying the license plate information. Some vehicles need to reverse and be re-identified, which delays the efficiency of release during peak vehicle travel periods. Summary of the invention

[0035] When a vehicle drives in front of the barrier arm 12, the camera 64 recognizes the vehicle information and feeds it back to the controller 22. The controller 22 controls the motor 31 to run, and controls the barrier arm 12 to rotate through the speed change component 4. The barrier arm 12 rotates and lifts the lever to release the vehicle. The barrier arm 12 is sensed and recognized by the infrared sensor 21 when it rotates the lever. According to the frequency of the barrier arm 12 rotating the lever, the peak time period of vehicle entry and exit is analyzed, and the speed of rotation of the barrier arm 12 is controlled and adjusted through the speed change component 4 so that vehicles can be quickly released during the peak time period.

[0037] The motor 31 controls the driving bevel gear 32 to rotate, and the driving bevel gear 32 drives the transmission bevel gear 34 to rotate through gear meshing transmission. The transmission bevel gear 34 controls the power rod 33 and the power gear 35 to rotate synchronously. The power gear 35 is meshed and assembled with the primary driving gear 42 to control the rotation of the primary driving gear 42 and the driving rod 41. The driving rod 41 drives the secondary driving gear 43 and the tertiary driving gear 44 to rotate synchronously. According to the frequency of vehicle entry and exit, the connection state of the speed change assembly 4 is adjusted to control the meshing and assembly of the secondary driving gear 43 and the secondary transmission gear 49, and the secondary transmission gear 49 is driven to rotate through meshing transmission. The secondary transmission gear 49 controls the rotation of the main transmission rod 45 and the gate arm 12.

[0038] The secondary transmission gear 49 is controlled to move laterally so that the secondary transmission gear 49 and the tertiary transmission gear 48 are connected and linked to each other. At this time, the secondary transmission gear 49 and the secondary drive gear 43 are separated from each other, and the tertiary transmission gear 48 is meshed and assembled with the tertiary drive gear 44. The tertiary transmission gear 48 is driven to rotate through the gear meshing transmission, and the tertiary transmission gear 48 drives the secondary transmission gear 49 to rotate synchronously. The secondary transmission gear 49 drives the gate arm 12 to decelerate and rotate through the main transmission rod 45.

[0039] The secondary transmission gear 49 is controlled to move laterally so that it is connected and linked with the primary transmission gear 46.
