Description

Technical Field

[0001] The present invention relates to the field of intelligent parking lots, and in particular to an efficient parking lot exit system and method based on a car transporter. Background Art

[0002] In the current existing technical solutions, the efficiency of vehicle departure depends on the driver's familiarity with the departure process and vehicle driving. Problems in any link will affect the efficiency of vehicle departure.

[0003] 1. The driver's driving habits or unfamiliarity with the exit process affect the efficiency of the exit. Currently in large parking lots, especially during peak hours, vehicles driving to the exit often need to queue up to take turns leaving. In order to speed up their departure, some drivers will not follow the queue order and try to insert themselves into the queue, which can easily cause traffic accidents and disputes between drivers, resulting in more congestion. Some drivers also have a lack of concentration on driving, resulting in the vehicle in front having already left but they still have not started the vehicle to move forward; in addition, in the existing technical solutions, most of them adopt an unmanned form, that is, there is no staff at the exit booth. When the driver has not paid in advance, he needs to wait for the staff to assist at the exit, which affects the departure of other vehicles;

[0004] 2. Inaccurate license plate recognition impacts exit efficiency. Existing technology solutions typically use a set of license plate recognition cameras at exit gates to perform a single license plate recognition. Inaccurate recognition requires on-site staff to confirm or retake the image. Furthermore, there are cases where two vehicles are too close together, preventing the license plate from being recognized by the cameras and preventing the vehicle from leaving the gate. Summary of the Invention

[0005] To overcome the aforementioned problems of the prior art, the present invention provides an efficient parking lot exit system and method based on a vehicle transporter. By installing a running track and a vehicle transporter in the parking lot exit passage, the wheels of vehicles arriving at the vehicle inspection area are clamped. After clamping, the vehicle transporter transports the vehicle along the running track to the exit without the driver having to drive the vehicle, achieving fully automatic exit operation and improving vehicle exit efficiency. Furthermore, by installing multiple recognition cameras alongside the running track, the license plate numbers of passing vehicles are recognized multiple times, thereby improving the accuracy of license plate number recognition.

[0031] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0032] like Figure 1 As shown, an efficient parking lot exit system based on a car transporter is applied to a parking lot. The system includes a running track 1, a controller, a vehicle transporter 4, and a wireless communication module. The running track 1 extends toward a parking lot exit 2 and reaches the parking lot exit 2. A vehicle detection area 3 is provided on the running track 1. An infrared sensor is provided at the vehicle detection area 3. The infrared sensor is used to identify whether a vehicle has entered the vehicle detection area 3.

[0033] The front and rear ends of the vehicle detection area 3 are respectively provided with a first recognition camera 5 and a second recognition camera 6; the first recognition camera 5 and the second recognition camera 6 are connected to the controller; by setting the first recognition camera 5 and the second recognition camera 6, the license plates of passing vehicles can be identified, and the identified vehicle information can be sent to the controller.

[0034] A barrier gate 7 is provided at the parking lot exit 2, and a rotating motor is provided inside the barrier gate 7; the rotating motor is connected to the controller; a lifting rod 71 is provided outside the barrier gate 7, and the lifting rod 71 is connected to the rotating motor; under the control of the controller, the rotating motor drives the lifting rod 71 to rise or fall;

[0035] The gate 7 is also provided with a third recognition camera 72, which is connected to the controller and is used to recognize the license plate number of the passing vehicle and send the recognized vehicle information to the controller.

[0036] By setting the first recognition camera 5, the second recognition camera 6 and the third recognition camera 72, the license plate numbers of passing vehicles can be recognized multiple times, thereby improving the accuracy of license plate number recognition.

[0037] The vehicle carrier 4 is connected to the controller, and the vehicle carrier 4 reciprocates along the travel track 1 under the control of the controller to move the vehicle in the vehicle detection area 3 to the parking lot exit 2;

[0038] When the infrared sensor recognizes that a vehicle enters the vehicle detection area 3, it sends a feedback signal to the controller. The controller controls the vehicle transporter 4 to move to the vehicle detection area 3 according to the received feedback signal and lifts the vehicle to the parking lot exit 2.

[0039] The controller is connected to the server via a wireless communication module; the controller sends the identification information received from each identification camera to the server to confirm the vehicle's license plate number and whether the vehicle has completed payment.

[0040] By arranging a running track and a vehicle carrier 4 in the parking lot departure passage, the wheels of vehicles arriving at the vehicle detection area 3 are clamped. After clamping, there is no need for the driver to drive the vehicle. The vehicle carrier 4 will transport the vehicle to the exit along the running track, realizing a fully automatic departure operation. The driver does not need to understand the method and location of departure, reducing the cost of learning the process for drivers in different parking lots and improving the efficiency of vehicle departure. The fully automatic departure mode of the vehicle carrier 4 is to set the departure path through the running track and the speed of the carrier through the vehicle carrier 4. It can adapt to the terrain of various types of departure passages, reduce the probability of accidents caused by improper operation, and reduce the driving skill requirements of the driver. By arranging multiple recognition cameras on the side of the running track, the license plate numbers of passing vehicles are repeatedly recognized, thereby improving the accuracy of license plate recognition of vehicles.

[0041] The vehicle transporter 4 includes a first traveling mechanism 41 and a second traveling mechanism 42 connected by a traction rope 43. The first traveling mechanism 41 and the second traveling mechanism 42 are respectively provided with a first sensor and a second sensor, each used to sense the front and rear wheels of the vehicle. The first and second sensors are connected to the controller, which controls the first and second traveling mechanisms 41 and 42 to move to a designated position based on the sensing information from the first and second sensors.

[0042] The first traveling mechanism 41 is provided with a left front wheel clamping bar 411 and a right front wheel clamping bar 412. The left front wheel clamping bar 411 and the right front wheel clamping bar 412 are symmetrically arranged. The left front wheel clamping bar 411 is used to clamp the left front wheel of the vehicle, while the right front wheel clamping bar 412 is used to clamp the right front wheel of the vehicle.

The left rear wheel clamping bar 421 is used to clamp the left rear wheel of the vehicle, while the right rear wheel clamping bar 422 is used to clamp the right rear wheel of the vehicle. The arrangement of the left front wheel clamping bar 411, the right front wheel clamping bar 412, the left rear wheel clamping bar 421, and the right rear wheel clamping bar 422 facilitates clamping the four wheels of the vehicle, allowing the vehicle to be moved with the vehicle transporter 4 to the parking lot exit 2.

[0044] S1: Vehicle detection: The driver drives the vehicle to the vehicle detection area. The infrared sensor in the vehicle detection area recognizes the vehicle entering and sends a signal to the controller. The controller controls the vehicle transporter to move to the vehicle detection area.

[0045] S2: Vehicle transport: The vehicle transporter arrives at the vehicle inspection area and stops under the vehicle. After accurately positioning the vehicle, the vehicle transporter extends a vehicle clamping rod from the running mechanism to clamp the four wheels of the vehicle, allowing the vehicle to move with the vehicle transporter;
