Description

Technical Field

[0001] The present invention relates to the field of unmanned aerial vehicles, and specifically to an intelligent parking system guided by a low-altitude unmanned aerial vehicle. Background Art

[0002] In the parking system of a parking lot, drivers observe whether there are parked vehicles on the signboards or in the parking spaces with the naked eye. Since a parking lot that can accommodate a large number of vehicles naturally has a large floor area, finding a parking space by human eyes often affects the efficiency too much. And without guidance, the parking of vehicles is irregular, and it is easy to have a situation where some parking spaces in remote corners are not parked for a long time. In a long-term working state, the unmanned aerial vehicle needs to repeatedly return to the charging station for charging, which is too inconvenient. Summary of the Invention

[0003] The present invention provides an intelligent parking system guided by a low-altitude unmanned aerial vehicle, which overcomes the deficiencies described in the background art.

[0004] The technical solution adopted by the present invention to solve its technical problems is as follows:

[0005] An intelligent parking system guided by a low-altitude unmanned aerial vehicle includes a processing module, a parking lot, and vehicles parked in the parking lot. There are parking spaces for parking vehicles in the parking lot. Each parking space is provided with a vehicle induction sensor for sensing vehicles. All vehicle induction sensors are signal-connected to the processing module. The processing module determines whether there is a parked vehicle in the corresponding parking space through all vehicle induction sensors. The processing module records the vehicles driving into the parking lot and the parking spaces without parked vehicles. There is a charging track and an unmanned aerial vehicle in the parking lot. The charging track is installed above the inner side of the parking lot and extends along the arrangement direction of the parking spaces;

[0006] The processing module calculates and statistics the distances between all parking spaces and the entrance of the parking lot respectively. When a vehicle drives into the parking lot, the unmanned aerial vehicle follows in front of the vehicle and guides the vehicle to drive to a parking space without a parked vehicle during flight;

[0007] The unmanned aerial vehicle is provided with a prompt light board, and when guiding the vehicle to drive, the prompt light board lights up.

[0008] In a preferred technical solution, the unmanned aerial vehicle includes a fuselage, a clamping part, and a motor two. The motor two is installed under the fuselage through the clamping part. The prompt light board is installed on the output shaft of the motor two. The prompt light board is in an inverted L-shaped structure. The prompt light board includes LED prompt lights arranged on its surface. The LED prompt lights are arranged at equal distances along the edge of the prompt light board;

[0009] All the prompt light boards are composed of a horizontal board and a vertical board. LED prompt lights are arranged on the surfaces of both the horizontal board and the vertical board. All the LED prompt lights installed on the horizontal board are powered by an external power supply and form a turn signal group. All the LED prompt lights installed on the vertical board are powered by an external power supply and form a guiding light group. When the drone guides the vehicle to drive and there is no need to guide the vehicle to turn, only the guiding light group is powered on and lit. When the drone guides the vehicle to turn, the motor two controls the horizontal board to rotate towards the turning direction, and the turn signal group is powered on and lit.

[0010] In a preferred technical solution, a guiding part is arranged near the connection end of the horizontal board and the vertical board. The guiding part includes a fixing board, a swinging board, a hinge, and a reciprocating adjusting mechanism for driving the swinging board to swing. The reciprocating adjusting mechanism is installed inside the fixing board. The swinging board is connected to the lower side of the fixing board through symmetrically arranged hinges. The swinging board is provided with an inclined surface, and a plurality of grating forming lights for manufacturing gratings are arranged on the inclined surface. When the drone guides the vehicle to drive into a parking space where there is no parked vehicle, the grating irradiated by the grating forming lights irradiates the parking space.

[0011] In a preferred technical solution, the reciprocating adjusting mechanism includes an outer housing. There are two interconnected chambers inside the outer housing. Movable telescopic push bars are arranged in both chambers. The two telescopic push bars are respectively connected to the inner sides of the corresponding chambers to form a piston connection. One of the chambers is externally connected to an air compressor through a trachea;

[0012] The two chambers are connected to each other through a communication hole. The communication hole is arranged on the side of the outer housing away from the trachea. The telescopic push bar abuts against the inner side of the chamber through a piston ring. Each chamber is divided into an upper chamber and a lower chamber through the corresponding piston ring. When the air compressor pressurizes the lower chamber of the interconnected chamber through the trachea, the telescopic push bar in this chamber moves upward against the surface of the outer housing as the pressure increases. When moving upward, the air in the upper chamber of this chamber is squeezed into the upper chamber of the other chamber, and the telescopic push bar arranged in this chamber moves downward;

[0013] The moving directions of the two telescopic push bars are opposite.

[0014] In a preferred technical solution, a charging track is also installed in the parking lot. The charging track is suspended above the inner side of the parking lot through a suspension rope arranged on its surface. The charging track is externally connected to a power supply and forms current conduction on its surface;

[0015] The clamping parts are symmetrically arranged, with a spacing between the two clamping parts. The second motor is installed on the lower side of one of the clamping parts. The fuselage includes a main power paddle, a sub-power paddle, and a charging terminal. The main power paddles are arrayed around the fuselage, the sub-power paddle is installed on the upper end face of the fuselage, and the charging terminal is arranged on the lower side of the fuselage. When the drone flies onto the charging track, the charging track passes through the space between the two clamping parts, and when the surface of the charging track abuts against the charging terminal, the drone is charged through the current conduction formed by the charging terminal and the charging track.

[0016] In a preferred technical solution, a wheeled airbag and a first motor are arranged inside the clamping part. The wheeled airbag and the output shaft of the first motor form a belt drive. When the drone flies onto the charging track, the wheeled airbags in the two clamping parts both abut against the clamping grooves arranged on both sides of the charging track.

[0017] Compared with the prior art, this technical solution has the following advantages:

[0018] Therefore, in the present invention, the processing module can be used to record the vehicle entry information and the information of the parking spaces without parked vehicles, and calculate the distances between each parking space and the entrance, so as to achieve precise management of the parking lot resources. According to the instructions of the processing module, the drone flies in front of the incoming vehicle and guides it to the nearest available parking space. At the same time, the indicating light board lights up to provide intuitive guidance for the driver and avoid disorderly parking. The charging track extends along the arrangement direction of the parking spaces, and the drone can be charged on it without frequently returning to the charging station, solving the problem of inconvenient charging of the drone and improving the operation efficiency of the system.

[0037] Vehicle 2. Detailed implementation manner

[0038] As Figures 1 to 10 shown, in the present invention, a smart parking system based on low-altitude drone guidance is proposed, which includes a processing module, a parking lot 1 and a vehicle 2 parked in the parking lot 1. The parking lot 1 is provided with parking spaces 200 for parking the vehicle 2, and each parking space 200 is provided with a vehicle induction sensor 201 for sensing the vehicle 2. All vehicle induction sensors 201 are signal-connected to the processing module. The processing module determines whether there is a vehicle parked in the corresponding parking space 200 through all vehicle induction sensors 201. It is characterized in that the processing module records the vehicle 2 driving into the parking lot 1 and the parking spaces 200 without parked vehicles 2. The parking lot 1 is provided with a charging track 101 and a drone 100. The charging track 101 is installed above the inner side of the parking lot 1 and extends along the arrangement direction of the parking spaces 200;

[0039] The processing module calculates and statistics the distances between all parking spaces 200 and the entrance of the parking lot 1 respectively. When the vehicle 2 enters the parking lot 1, the drone 100 follows in front of the vehicle 2 and guides the vehicle 2 to a parking space 200 where no vehicle is parked during flight; the drone 100 is provided with a prompt light board 14, and when guiding the vehicle 2 to drive through the drone 100, the prompt light board 14 lights up.

[0040] Therefore, in the present invention, the processing module 1 can record the vehicle entry information and the information of the parking spaces 200 where no vehicle is parked, and calculate the distances between the parking spaces 200 and the entrance, so as to achieve precise management of the parking lot resources. The drone 100 follows the vehicle 2 flying in front according to the instructions of the processing module 1, guides it to the nearest available parking space 200, and at the same time the prompt light board 14 lights up to provide intuitive guidance for the driver and avoid disorderly parking. The charging track 101 extends along the arrangement direction of the parking spaces 200, and the drone 100 can be charged on it without having to return to the charging station frequently, solving the problem of inconvenient charging of the drone and improving the operating efficiency of the system;

[0041] The working principle of this intelligent parking system is as follows:

[0042] Vehicle induction and information recording, when the vehicle 2 enters the parking lot 1, the processing module 1 monitors the occupancy status of each parking space 200 in real time through the vehicle induction sensor 201, and records the vehicle entry information and the available parking space information.

[0043] Path planning and guidance, the processing module 1 calculates the optimal parking path according to the distance between the parking space 200 and the entrance. After receiving the instruction, the drone 100 takes off automatically and flies in front of the vehicle 2 entering. By lighting up the prompt light board 14, it guides the vehicle to drive along the planned path to the nearest available parking space 200.

[0044] Drone charging and endurance management, after the drone 100 completes the guidance task, it can fly along the charging track 101 to the charging station for charging, without having to return to the fixed charging point frequently, so as to achieve efficient endurance management and ensure the continuous operation of the system.

[0045] Furthermore, the drone 100 includes a fuselage 11, a clamping part 12 and a motor two 13. The motor two 13 is installed on the lower side of the fuselage 11 through the clamping part 12. The prompt light board 14 is installed on the output shaft of the motor two 13. The prompt light board 14 is in an inverted L-shaped structure. The prompt light board 14 includes LED prompt lights 143 arranged on its surface at equal intervals along the edge of the prompt light board 14;

[0046] All the prompt light boards 14 are composed of a horizontal board 141 and a vertical board 142. LED prompt lights 143 are arranged on the surfaces of both the horizontal board 141 and the vertical board 142. All the LED prompt lights 143 installed on the horizontal board 141 are powered by an external power supply and form a turn signal group. All the LED prompt lights 143 installed on the vertical board 142 are powered by an external power supply and form a guiding light group. When the drone 100 guides the vehicle 2 and there is no need to guide the vehicle 2 to turn, only the guiding light group is powered on and lit. When the drone 100 guides the vehicle 2 to turn, the motor two 13 controls the horizontal board 141 to rotate towards the turning direction, and the turn signal group is powered on and lit;

[0047] This technical solution is based on the collaborative work of the drone 100 and the processing module 1, and optimizes the parking process through the guiding function of the drone. When the vehicle 2 drives into the parking lot 1, the processing module 1 real-time monitors the occupancy status of the parking spaces 200 through the vehicle induction sensor 201 and calculates the distance between each parking space and the entrance. Subsequently, the processing module 1 instructs the drone 100 to take off according to the parking space information to guide the vehicle to the nearest available parking space. During the guiding process, the guiding light group on the vertical board 142 lights up to provide front guiding for the vehicle. When it is necessary to guide the vehicle to turn, the motor two 13 drives the horizontal board 141 to rotate towards the turning direction, and at the same time, the turn signal group on the horizontal board lights up to prompt the vehicle to turn. In addition, after the drone 100 completes the guiding task, it can fly along the charging track 101 to the charging station for charging, avoiding frequent returns to the fixed charging point. This design not only improves the battery life of the drone but also ensures the efficient operation of the system;

[0048] It can be seen that through the guiding function of the drone 100, the vehicle 2 can quickly find an available parking space, avoiding the time and fuel wasted in searching for parking spaces in traditional parking lots. Secondly, the innovative design of the prompt light board 14, combined with the guiding light group and the turn signal group, provides intuitive visual guidance for the driver, improving the safety and convenience of parking. In addition, the design of the charging track 101 solves the problem of inconvenient charging of the drone, enabling it to charge flexibly in the parking lot without frequent returns to the charging station. This charging method not only improves the battery life of the drone but also reduces the operating cost of the system. At the same time, the system optimizes the utilization rate of parking spaces through the real-time monitoring and management of parking space information by the processing module 1, avoiding the situation of some parking spaces being idle for a long time.

[0049] Moreover, a guiding portion 15 is provided near the connection end of the horizontal plate 141 and the vertical plate 142. The guiding portion 15 includes a fixing plate 151, a swing plate 152, a hinge 153, and a reciprocating adjustment mechanism 154 for driving the swing of the swing plate 152. The reciprocating adjustment mechanism 154 is installed in the fixing plate 151. The swing plate 152 is connected to the lower side of the fixing plate 151 through symmetrically arranged hinges 153. The swing plate 152 is provided with an inclined surface, and a plurality of grating forming lamps 155 for manufacturing gratings are arranged on the inclined surface. When the drone 100 guides the vehicle 2 to drive into the parking space 200 where no vehicle 2 is parked, the grating manufactured by the grating forming lamps 155 irradiates the parking space 200. The formation of the grating is formed by the reciprocating adjustment mechanism 154 repeatedly adjusting the swing of the swing plate 152. By expanding the irradiation surface of the grating, the visibility of the drone 100 is improved, so that the driver of the vehicle 2 to be guided can clearly observe the target parking space 200.

[0050] Under this technical solution, the drone 100 provides precise parking guidance for the vehicle 2 through the synergistic effect of the prompt light plate 14 and the guiding portion 15. When the vehicle enters the parking lot, the processing module 1 instructs the drone to take off according to the parking space information and guides the vehicle to the nearest available parking space. During this process, the guiding lamp group of the prompt light plate 14 lights up to provide front guidance for the vehicle; when turning, the turning lamp group on the horizontal plate 141 lights up to indicate the turning direction of the vehicle. The key lies in the role of the guiding portion 15. When the vehicle approaches the target parking space 200, the reciprocating adjustment mechanism 154 of the guiding portion 15 drives the swing plate 152 to swing, and the grating forming lamps 155 manufacture gratings and expand the irradiation range. The grating clearly marks the boundary of the parking space, helping the driver quickly identify the parking position. The formation process of this dynamic grating is realized through the reciprocating movement of the swing plate 152, enhancing the visibility and accuracy of the guidance. Especially in the case of dim light or narrow parking spaces, it can significantly improve the convenience of parking. In addition, after completing the guiding task, the drone 100 can fly along the charging track 101 to the charging station for charging, without frequently returning to the fixed charging point, thereby improving the operating efficiency of the system and the battery life of the drone. The entire system realizes an efficient and precise parking experience through intelligent parking space management and guiding functions, solving the problems of difficult parking space search and low parking efficiency in traditional parking lots;

[0051] The drone 100 provides accurate parking guidance for the vehicle 2 through the synergistic effect of the prompt light plate 14 and the guide part 15. When the vehicle enters the parking lot, the processing module 1 instructs the drone to take off according to the parking space information and guides the vehicle to the nearest vacant parking space. In this process, the guide light group of the prompt light plate 14 lights up to provide the vehicle with forward guidance; when turning, the turn signal group on the cross plate 141 lights up to indicate the direction of the vehicle's turn. The key lies in the role of the guide part 15. When the vehicle approaches the target parking space 200, the reciprocating adjustment mechanism 154 of the guide part 15 drives the swing plate 152 to swing, and the grating forming lamp 155 creates a grating and expands the irradiation range. The grating clearly marks the location of the parking space, helping the driver to quickly identify the parking position. This dynamic grating formation process is achieved through the reciprocating motion of the swing plate 152, which enhances the conspicuousness and accuracy of the guidance, especially in the case of dim light or narrow parking space, which can significantly improve the convenience of parking. In addition, after completing the guidance mission, the drone 100 can fly along the charging track 101 to the charging station for charging, without having to frequently return to a fixed charging point, thereby improving the operating efficiency of the system and the endurance of the drone. The entire system achieves an efficient and accurate parking experience through intelligent parking space management and guidance functions, solving the problems of difficulty in finding parking spaces and low parking efficiency in traditional parking lots.

[0052] Furthermore, the reciprocating adjustment mechanism 154 includes an outer shell 541, in which two interconnected chambers 542 are provided, and movable telescopic push strips 543 are provided in the two chambers 542, and the two telescopic push strips 543 are respectively connected to the inner side of the corresponding chamber 542 to form a piston connection, and one of the chambers 542 is connected to an air compressor through an air pipe 544;

[0053] The two chambers 542 are connected through a connecting hole 5421, and the connecting hole 5421 is arranged on the side of the outer shell 541 away from the air pipe 544. The telescopic push strip 543 is against the inner side of the chamber 542 through the piston ring. Each chamber 542 is divided into upper and lower chambers by the corresponding piston ring. When the air compressor increases the pressure toward the lower chamber of the connected chamber 542 through the air pipe 544, the telescopic push strip 543 in the chamber 542 moves upward and pushes out of the surface of the outer shell 541 as the pressure increases, and when moving upward, it squeezes the air in the upper chamber of the chamber 542 into the upper chamber of the other chamber 542, and allows the telescopic push strip 543 arranged in the chamber 542 to move downward. The movement directions of the two telescopic push strips 543 are opposite.

[0054] This pneumatic drive mechanism can respond quickly to achieve high-frequency reciprocating motion of the swing plate 152, enabling the grating formed by the grating forming lamp 155 to form a dynamic grating on the parking space 200, expanding the irradiation range and enhancing the visual effect. When the vehicle 2 approaches the target parking space, the dynamic grating can clearly mark the boundary of the parking space, helping the driver quickly identify the parking position and improving parking efficiency and safety. In addition, the pneumatic design of the reciprocating adjustment mechanism 154 features high reliability and low maintenance costs. The pneumatic drive can adapt to complex working environments, reduce mechanical wear, and respond quickly to ensure the smoothness and real-time nature of the guiding process. Through the guidance of the dynamic grating, the system can effectively solve the parking difficulty problem caused by unclear signs in traditional parking lots, especially in the case of dim light or narrow parking spaces, significantly improving the parking experience.

[0055] In a preferred technical solution, a charging track 101 is further installed in the parking lot 1. The charging track 101 is suspended above the inner side of the parking lot 1 by a suspension rope 102 provided on its surface. The charging track 101 is externally connected to a power source and forms current conduction on its surface.

[0056] The clamping parts 12 are symmetrically arranged, and there is a distance between the two clamping parts 12. The second motor 13 is installed on the lower side of one of the clamping parts 12. The fuselage 11 includes a main power paddle 111, a sub-power paddle 112, and a charging end 113. The main power paddles 111 are arrayed around the fuselage 11, the sub-power paddle 112 is installed on the upper end surface of the fuselage 11, and the charging end 113 is arranged on the lower side of the fuselage 11. When the drone 100 flies onto the charging track 101, the charging track 101 passes through the space between the two clamping parts 12, and when the surface of the charging track 101 abuts against the charging end 113, the drone 100 is charged through the current conduction formed by the charging end 113 and the charging track 101. When the drone 100 flies onto the charging track 101, in order to prevent the fuselage of the drone 100 from tilting too much when the main power paddle 111 adjusts the flight direction of the drone 100, the drone 100 can be driven forward or backward on the charging track 101 by the forward and reverse rotation of the sub-power paddle 112 installed on the drone 100.

[0057] In a preferred technical solution, a wheeled airbag 121 and a first motor 122 are provided in the clamping part 12. The wheeled airbag 121 and the output shaft of the first motor 122 form a belt drive. When the drone 100 flies onto the charging track 101, the wheeled airbags 121 in the two clamping parts 12 both abut against the card slots 1011 provided on both sides of the charging track 101.

[0058] According to the above content, it can be known that the drone 100 in the present invention, under the design of the symmetric clamping parts 12, can have the ability to fly onto the charging track 101 and fly away from the charging track 101. Since the charging track 101 has a certain current transmission effect after being electrified, in this technical solution, different from the drone cruise system and device in the prior art, the drone 100 in the present invention has the characteristics of continuous power replenishment and long-time operation. When flying onto or flying away from the charging track 101, it is necessary to control the prompt light board 14 to rotate through the second motor 13, so that the cross board 141 rotates to not block the distance and opening between the two clamping parts 12, to avoid hitting the cross board 141 when the drone 100 flies or flies away from the charging track 101 and affecting the flight safety of the drone 100;

[0059] Secondly, during the construction of the parking lot, beams for increasing the ceiling support will be built on the top of the building body of the parking lot, and the beams often protrude more than twenty centimeters above the ceiling surface. In this case, when installing the charging track 101, the charging track 101 needs to be divided into multiple sections and installed sequentially. In order to ensure the continuity of the drone 100 flying onto the charging track 101 and the continuity of guiding the vehicle 2 to drive, when the drone 100 flies from one section of the charging track 101 to another section of the charging track 101, the LED prompt lamp 143 on the cross board 141 will continuously light up during the flight of the drone 100 to another section of the charging track 101, and the cross board 141 will be turned to the direction of the target charging track 101 through the second motor 13, so that the driver can clearly understand the flight situation of the drone 100 and the change of the time guiding state.

[0060] Through the innovative design of the charging track 101 and the drone 100, the present invention significantly improves the operation efficiency and safety of the drone in the parking lot. The traditional drone charging method is limited by fixed charging points, resulting in inconvenient charging and limited battery life. The charging track 101 in the present invention realizes continuous charging of the drone through segmented installation and current conduction design, solves the problem of inconvenient charging of traditional drones, enables it to work in the parking lot for a long time without frequently returning to the charging station.

[0061] In addition, the design of the clamping parts 12 and the wheeled airbags 121 of the drone 100 ensures its stable clamping and movement on the charging track, improving the reliability of the charging process. The design of the auxiliary power paddle 112 further enhances the stability of the drone during charging, avoids the fuselage tilting due to the adjustment of the main power paddle direction, and ensures the smooth progress of the charging process.

[0062] As described above, it is only a preferred embodiment of the present invention. Therefore, the scope of implementation of the present invention cannot be limited thereby. That is, equivalent changes and modifications made according to the scope of the present invention patent and the content of the specification should still fall within the scope covered by the present invention.
