Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicle (UAV) supervision, and in particular to a low-altitude intelligent parking system and method for unmanned aerial vehicles. Background Art

[0002] With the development of economy and the progress of science and technology, the number of cars is increasing year by year, while the increase rate of parking spaces is far less than that of vehicles, which will lead to a shortage of parking spaces. At present, when a driver drives into an underground parking lot, he can only obtain the number of free parking spaces in the parking lot through the parking lot management system, but cannot determine the location of the free parking spaces in the parking lot. As a result, the driver needs to spend a lot of time searching row by row in the parking lot. He can only park when he sees an empty parking space. If he has not found an empty parking space, he can only continue to drive back and forth. The above method of the driver driving into the parking lot to find an empty parking space is obviously not convenient enough.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. Improve parking efficiency: Traditional parking methods often require drivers to circle the ground to find empty parking spaces, which not only wastes time but also increases the risk of traffic congestion. The present invention uses drones to mark empty parking spaces in real time and use drones to release marking banners above the empty parking spaces. Drivers can quickly obtain information, reduce the time spent looking for parking spaces, and improve overall parking efficiency.

[0015] 2. Enhance visibility and recognition: Drones fly at low altitudes to mark empty parking spaces, and use brightly colored marking banners hung in the sky, which are more conspicuous in complex environments, so that drivers can clearly identify them even at a long distance, avoiding the problem of missing empty parking spaces due to obstruction of vision in existing parking methods.

[0016] 3. Reduce the risk of vehicle collision: Through accurate information transmission and prominent signs, drivers can find parking locations faster and more clearly, thereby reducing sudden stops, sharp turns and other operations, reducing the risk of collisions that may be caused in the process of finding parking spaces, and improving driving safety.

[0017] 4. Environmental protection and space utilization: The implementation of this system not only reduces vehicle idling emissions caused by long-term search for parking spaces, but also effectively manages the use of parking spaces dynamically. Drones can monitor the use of parking spaces in real time and provide timely feedback to the parking management system, thereby optimizing parking space allocation and improving space utilization.

[0018] 5. Cost saving: Compared with setting up a motor in each base to drive the roller and installing a sensor in each parking space to detect the vehicle status, using a drone to identify and drive the winding and unwinding of the marking banner can greatly reduce costs. At the same time, the purely mechanical marking device is also easy to install and maintain. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] 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.

[0022] like Figures 1 to 7 As shown, a low-altitude smart parking system of a drone 1 includes a control system, a plurality of drones 1, and a plurality of marking devices respectively arranged on each parking space in an underground parking lot, wherein the marking devices are installed on the ceiling above the corresponding parking space, and a camera module 23 is arranged on the drone 1 to inspect and identify the parking conditions of the parking space in the parking lot, and the drone 1 is in communication connection with the control system; The marking device includes a base 2 and a marking banner 3. The base 2 is installed on the ceiling above the parking space, and a transmission component is arranged inside the base 2. The marking banner 3 passes through the bottom of the base 2 and is connected to the transmission component. The drone 1 is provided with a power component 22. The power component 22 can be engaged with the transmission component and drive the transmission component to work. When the transmission component works, the marking banner 3 can be rolled up or unrolled, so that the drone 1 detects the vehicle condition of the parking space and is connected to the transmission component to drive the retracted and unrolled state of the marking banner 3 to mark the vehicle condition of the parking space below. The existing parking spaces are blocked by the vehicles next to them, and the driver's ground vision is limited. The driver can only search by row and position, while the device sets the marking banner 3 on the ceiling, so that the area above the parking lot will not be blocked, and the vision is wide. The driver can see the condition of the ceiling from a distance, so as to intuitively know the location of the empty parking space. The driver only needs to drive towards the marking banner 3.

[0023] See also Figure 1 , Figure 2 and Figure 7 As shown, the power assembly 22 includes a support member 4 and a connecting block 5. The support member 4 is installed at the middle of the top of the fuselage of the drone 1. The other end of the support member 4 extends upward and is higher than the propeller of the drone 1, and the end thereof is rotatably connected to the connecting block 5. A clamping hole 6 is provided in the middle of the top of the connecting block 5. A connecting rod 7 is provided at the bottom end of the base 2. The connecting rod 7 is transmission-connected to the transmission assembly. A clamping block 8 is provided at the bottom end of the connecting rod 7. The clamping block 8 and the clamping hole 6 can be engaged with each other. A motor 9 is provided on the support member 4. The motor 9 is transmission-connected to the connecting block 5 to drive the connecting block 5 to rotate, so that after being connected to the clamping block 8, the transmission assembly can be driven to operate to retract and release the marking banner 3. See also Figure 5 , Figure 6 and Figure 7 As shown, the transmission assembly includes a roller 10, a transmission rod 11 and a synchronous belt 12. The roller 10 and the transmission rod 11 are rotatably assembled on the front and rear sides of the base 2 respectively. Two pulleys 13 are respectively arranged on the rotating shafts of the roller 10 and the transmission rod 11, and a synchronous belt 12 is sleeved between the two pulleys 13. The marking banner 3 is connected to the roller 10 and is retracted and unwound as the roller 10 rotates. A through hole 14 is opened on the front side of the bottom of the base 2. The other end of the marking banner 3 passes through the through hole 14 and extends to the bottom of the base 2. The connecting rod 7 passes through the bottom of the base 2 and is rotatably connected to the bottom of the base 2. The top of the connecting rod 7 and the transmission rod 11 are driven by a bevel gear. The bottom end of the marking banner 3 is connected to the counterweight rod; The drone 1 flies upwards in alignment with the connecting rod 7, so that the connecting block 5 on it is plugged and engaged with the block 8 of the connecting rod 7 through the card hole 6, and then the motor 9 drives the connecting block 5 to rotate, thereby synchronously driving the connecting rod 7 to rotate, and the rotation of the connecting rod 7 will drive the transmission rod 11 to rotate, and then drive the roller 10 to rotate through the synchronous belt 12. The roller 10 rotates clockwise to reel in the marking banner 3 on it, and rotates counterclockwise to release the marking banner 3. The marking banner 3 is released from the opening 14 and is kept vertically hanging on the base 2 under the gravity of the counterweight rod; therefore, the reeling and unreeling of the marking banner 3 is controlled by the forward and reverse rotation of the motor 9 on the drone 1; The reason why the roller 10 is not driven to rotate directly by the connecting rod 7 but is driven indirectly by the transmission rod 11 and the synchronous belt 12 is to make the connecting rod 7 and the marking banner 3 have a certain distance, so that when the UAV 1 flies to the connecting rod 7, its propeller will not be close to the marking banner 3, avoiding contact with the marking banner 3 and causing damage to the UAV 1; if the roller 10 is rotated directly by the connecting rod 7, and there is a certain distance between the through hole 14 and the roller 10, although such a design can also avoid contact between the UAV 1 and the marking banner 3, the excessive distance between the roller 10 and the through hole 14 will affect the winding of the marking banner 3 and easily cause wear of the marking banner 3.

[0024] The marking banner 3 is made of brightly colored cloth, so that it is more obvious whether there is a hanging marking banner 3 on the base 2, which is convenient for the driver to observe at the first time.

[0025] See also Figure 2 and Figure 7 As shown, the connecting block 5 is a truncated cone structure that is narrow at the top and wide at the bottom, the clamping hole 6 and the clamping block 8 are both regular hexagonal structures, the bottom end of the connecting rod 7 is provided with a socket 15 that is compatible with the connecting block 5, and the clamping block 8 is installed in the middle of the inner wall at the top of the socket 15; Since the socket 15 is an opening structure that is narrow at the top and wide at the bottom, and is matched with the connecting block 5 of a truncated cone structure, when the drone 1 flies upward with the connecting rod 7 in alignment, the lower end opening of the socket 15 is larger, while the top end of the connecting block 5 is smaller, so the connecting block 5 can easily enter the socket 15, and under the limiting and guiding action of the inner wall of the socket 15 which becomes narrower as it goes upwards, the connecting block 5 will gradually deviate to the middle of the socket 15, and finally the card hole 6 and the card block 8 thereon will be plugged in.

[0026] See also Figure 1 and Figure 3 As shown, a sensor 21 is provided on the top of the fuselage of the drone 1. The sensor 21 is used to detect the engagement status of the power assembly 22 and the transmission assembly. The sensor 21 is electrically connected to the internal processor of the drone 1. The sensor 21 (vision) is used to monitor the alignment status of the connecting block 5 and the connecting rod 7 in real time, and the flight direction is adjusted in time to align the connecting block 5 with the connecting rod 7.

[0027] See also Figure 1 and Figure 2 As shown, the support member 4 includes a support seat 16, a plurality of support rods 17 and a mounting seat 18. The support seat 16 is assembled on the top of the fuselage of the drone 1. The plurality of support rods 17 are arranged and mounted on the top of the support seat 16. A pressure rod 19 is slidably penetrated through the top of each support rod 17. The mounting seat 18 is arranged between the tops of each pressure rod 19. A spring 20 is sleeved on the surface of the pressure rod 19. The two ends of the spring 20 are respectively fixedly connected to the bottom surface of the mounting seat 18 and the top surface of the support rod 17. The block 8 and the motor 9 are both arranged on the mounting seat 18. An elastic connection design is adopted between the connecting block 5 and the drone 1. When the connecting block 5 enters and abuts against the socket 15 of the connecting rod 7, and the clamping block 8 is plugged into the clamping hole 6, if the drone 1 does not stop in time and continues to fly upward, the pressure rod 19 will be retracted into the support rod 17 and the spring 20 will be compressed, thereby forming a buffer distance, reducing the force of the drone 1 colliding with the connecting rod 7 when flying upward, and avoiding the problem that the rigid connection may cause damage to the drone 1.

[0028] This embodiment also provides a low-altitude smart parking method for a drone 1, using the above-mentioned low-altitude smart parking system for a drone 1, the parking method includes the following steps: S1: The drone 1 performs a low-altitude inspection in the parking lot, and the camera module 23 on the drone 1 is turned on to collect images of the area below the drone 1; S2: UAV 1 detects the image and identifies whether there is a vehicle parked in the parking space from the image; S3: The drone 1 moves to the top of the parking space and continues to fly upwards towards the base 2 until the power assembly 22 is aligned and engaged with the transmission assembly and then hovers; S4: starting the power assembly 22 to work, and according to the identified parking situation of the vehicle, if there is a parked vehicle, controlling the marking banner 3 to be rolled up, and if there is no parked vehicle, controlling the marking banner 3 to be unrolled; S5: The driver can look up and observe the marking banner 3 hanging from the ceiling from a distance, and can intuitively determine the location of the vacant parking space. The driver only needs to drive on the main lane, and can determine whether there is a vacant parking space by observing whether there is a marking banner 3 hanging from the ceiling above the parking areas on both sides, without having to drive into the branch lane and slowly search for each parking space one by one.

[0029] Among them, in step S1, the original fixed cameras in the parking lot can be used to monitor the entry and exit of vehicles on each lane through the cameras to assist the drone 1 in patrolling, so that the drone 1 can quickly fly to the target area to mark the vacant parking space after the vehicle leaves.

[0030] Among them, in step S2, after the drone 1 identifies the vacant parking space, it uploads the information to the control system for analysis, and the control system then uploads the number and location of the vacant parking spaces in the parking lot to the display screen in the parking lot for display, so that the driver can observe the display screen to understand the area where the vacant positions are located, and after driving to the target area, he can see the marking banner 3 from a distance, which is convenient for the driver to find the vacant parking space more quickly.

[0031] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
