However, a parking lot that can accommodate a large number of vehicles naturally occupies too large an area. Searching for parking spaces by human eyes often affects efficiency too much. In the absence of guidance, vehicles are parked in a disorderly manner, and it is easy for some parking spaces in remote corners to have no vehicles parked for a long time. When working for a long time, the drone needs to return to the charging station repeatedly for charging, which is too inconvenient. Summary of the invention

[0023] Vehicle 2. DETAILED DESCRIPTION

[0024] like Figures 1 to 10 As shown, the present invention proposes a smart parking system based on low-altitude drone guidance, including a processing module, a parking lot 1 and a vehicle 2 parked in the parking lot 1, the parking lot 1 is provided with a parking space 200 for parking the vehicle 2, each parking space 200 is provided with a vehicle sensing sensor 201 for sensing the vehicle 2, all vehicle sensing sensors 201 are connected to the processing module signal, and the processing module determines whether there is a vehicle parked in the corresponding parking space 200 through all vehicle sensing sensors 201, characterized in that the processing module records the vehicle 2 driving into the parking lot 1 and the parking space 200 where no vehicle 2 is parked, the parking lot 1 is provided with a charging track 101 and a drone 100, the charging track 101 is installed on the upper inner side of the parking lot 1, and the charging track 101 extends along the arrangement square of the parking space 200; The processing module calculates and counts the distances between all parking spaces 200 and the entrance of parking lot 1. When vehicle 2 enters parking lot 1, drone 100 follows in front of vehicle 2 and guides vehicle 2 to a parking space 200 where no vehicle 2 is parked during flight. The drone 100 is provided with a prompt light panel 14. When the drone 100 guides vehicle 2 to drive, the prompt light panel 14 lights up.

[0025] Therefore, in the present invention, the processing module 1 can be used to record the entry information of the vehicle 2 and the parking space 200 information without the vehicle 2 parked, and calculate the distance between each parking space 200 and the entrance, so as to achieve accurate management of parking resources. According to the instructions of the processing module 1, the drone 100 flies in front of the entering vehicle 2 and guides it to the nearest vacant parking space 200. At the same time, the prompt light panel 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 frequently returning to the charging station, which solves the inconvenience of drone charging and improves the system operation efficiency; The working principle of the smart parking system is as follows: Vehicle sensing and information recording: When a 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 sensing sensor 201, and records the entering vehicle information and available parking space information.

[0026] 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 command, the drone 100 automatically takes off and flies to the front of the incoming vehicle 2. By lighting up the prompt light panel 14, the vehicle is guided to drive along the planned path to the nearest vacant parking space 200.

[0027] UAV charging and endurance management, after completing the guidance mission, the UAV 100 can fly along the charging track 101 to the charging station for charging, without the need to frequently return to a fixed charging point, thereby achieving efficient endurance management and ensuring continuous operation of the system.

[0028] Furthermore, the drone 100 includes a fuselage 11, a clamping portion 12, and a second motor 13. The second motor 13 is mounted on the lower side of the fuselage 11 through the clamping portion 12. The prompt light plate 14 is mounted on the output shaft of the second motor 13. The prompt light plate 14 is an inverted L-shaped structure. The prompt light plate 14 includes LED prompt lights 143 arranged on its surface. The LED prompt lights 143 are arranged equidistantly along the edge of the prompt light plate 14. All the prompt light panels 14 are composed of a horizontal panel 141 and a vertical panel 142. The surfaces of the horizontal panel 141 and the vertical panel 142 are both provided with LED prompt lights 143. All the LED prompt lights 143 installed on the horizontal panel 141 are powered by an external power supply and form a turn signal group. All the LED prompt lights 143 installed on the vertical panel 142 are powered by an external power supply and form a guide light group. When the drone 100 guides the vehicle 2 to drive and does not need to guide the vehicle 2 to turn, only the guide light group is powered on and lights up. When the drone 100 guides the vehicle 2 to turn, the motor 2 13 controls the horizontal panel 141 to rotate in the direction of the turn, and the turn signal group is powered on and lights up. 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 guidance function of the drone. When the vehicle 2 enters the parking lot 1, the processing module 1 monitors the occupancy status of the parking space 200 in real time through the vehicle sensing 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 and guides the vehicle to the nearest vacant parking space. During the guidance process, the guide light group on the vertical plate 142 lights up to provide forward guidance for the vehicle. When it is necessary to guide the vehicle to turn, the motor 2 13 drives the horizontal plate 141 to rotate in the turning direction, and the turn signal group on the horizontal plate lights up to prompt the vehicle to turn. In addition, after completing the guidance task, the drone 100 can fly along the charging track 101 to the charging station for charging, avoiding frequent returns to a fixed charging point. This design not only improves the endurance of the drone, but also ensures the efficient operation of the system; It can be seen that through the guidance function of the drone 100, the vehicle 2 can quickly find an empty 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 panel 14, combined with the guide light group and the turn signal group, provides the driver with intuitive visual guidance, improving the safety and convenience of parking. In addition, the design of the charging track 101 solves the problem of inconvenient charging of drones, allowing them to be charged flexibly in the parking lot without frequently returning to the charging station. This charging method not only improves the endurance 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 real-time monitoring and management of parking space information by the processing module 1, avoiding the situation where some parking spaces are idle for a long time.

[0029] In addition, a guide portion 15 is provided near the connecting end of the horizontal plate 141 and the vertical plate 142, and the guide portion 15 includes a fixed plate 151, a swing plate 152, a hinge 153 and a reciprocating adjustment mechanism 154 for driving the swing plate 152 to swing, the reciprocating adjustment mechanism 154 is installed in the fixed plate 151, the swing plate 152 is connected to the lower side of the fixed plate 151 through the symmetrically arranged hinges 153, the swing plate 152 is provided with an inclined surface, and a plurality of grating forming lamps 155 for making gratings are arranged on the inclined surface, and when the drone 100 guides the vehicle 2 to drive into a parking space 200 where no vehicle 2 is parked, the parking space 200 is illuminated by the gratings made by the grating forming lamps 155, and the gratings are formed by repeatedly adjusting the swing plate 152 by the reciprocating adjustment mechanism 154 to swing and form, and the conspicuousness of the drone 100 is improved by expanding the illumination surface of the grating, so that the driver of the guided vehicle 2 can clearly observe the target parking space 200.

[0030] Under this technical solution, the drone 100 provides accurate parking guidance for the vehicle 2 through the synergy 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 forward guidance for the vehicle; 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 boundary 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; 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.

[0031] 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; 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. This pneumatic drive mechanism can respond quickly and realize high-frequency reciprocating motion of the swing plate 152, so that the grating manufactured by the grating forming lamp 155 forms a dynamic grating on the parking space 200, expanding the illumination 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 to quickly identify the parking position and improve parking efficiency and safety. In addition, the pneumatic design of the reciprocating adjustment mechanism 154 has the characteristics of high reliability and low maintenance cost. Pneumatic drive can adapt to complex working environments, reduce mechanical wear, and respond quickly to ensure the smoothness and real-time nature of the guidance process. Through the guidance of the dynamic grating, the system can effectively solve the problem of parking difficulties caused by unclear signs in traditional parking lots, especially in dim light or narrow parking spaces, which significantly improves the parking experience.

[0032] A preferred technical solution is that a charging track 101 is also installed in the parking lot 1. The charging track 101 is suspended above the inner side of the parking lot 1 by a hanging rope 102 arranged on its surface. The charging track 101 is connected to an external power source and forms current conduction on its surface. The clamping parts 12 are symmetrically arranged, with a spacing between the two clamping parts 12. The motor 2 13 is installed on the lower side of one of the clamping parts 12. The fuselage 11 includes a main power propeller 111, an auxiliary power propeller 112 and a charging terminal 113. The main power propeller 111 is arrayed around the fuselage 11, the auxiliary power propeller 112 is installed on the upper end surface of the fuselage 11, and the charging terminal 113 is arranged on the lower side of the fuselage 11. When the drone 100 flies to the charging track 101, the charging track 101 passes through the two clamping parts 12. When the surface of the charging track 101 is against the charging terminal 113, the UAV 100 is charged by the current conduction formed by the charging terminal 113 and the charging track 101. When the UAV 100 flies to the charging track 101, in order to avoid the fuselage of the UAV 100 being too tilted when the main power propeller 111 adjusts the flight direction of the UAV 100, the auxiliary power propeller 112 installed on the UAV 100 can be rotated forward and reversely to drive the UAV 100 forward or backward on the charging track 101; A preferred technical solution, the clamping part 12 is provided with a wheeled airbag 121 and a motor 122, the wheeled airbag 121 and the output shaft of the motor 122 form a belt drive, when the drone 100 flies to the charging track 101, the wheeled airbags 121 in the two clamping parts 12 are against the clamping grooves 1011 provided on both sides of the charging track 101; According to the above content, the drone 100 of the present invention can be designed with a symmetrical clamping part 12, so that it can fly to 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 conductive, the drone 100 of the present invention has the characteristics of continuous replenishment of electric energy and long-term operation in this technical solution, which is different from the drone patrol system and device in the prior art. When flying to the charging track 101 or flying away, it is necessary to control the prompt light plate 14 to rotate through the motor 2 13, so that the horizontal plate 141 rotates to not block the spacing and opening between the two clamping parts 12, so as to avoid the drone 100 from hitting the horizontal plate 141 when flying or flying away from the charging track 101, which affects the flight safety of the drone 100; Secondly, during the construction of the parking lot, a beam is built on the top of the building to increase the support of the ceiling, and the beam often protrudes more than 20 centimeters from 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 and constructed in sequence. In order to ensure the continuity of the UAV 100 flying to the charging track 101 and the continuity of guiding the vehicle 2 to travel, when the UAV 100 flies from one section of the charging track 101 to another section of the charging track 101, the LED prompt light 143 on the horizontal board 141 will continue to light up during the flight of the UAV 100 to the other section of the charging track 101, and the horizontal board 141 will be turned to the direction of the target charging track 101 through the motor 2 13, so that the driver can clearly understand the flight status of the UAV 100 and the changes in the guidance status over time.

[0033] The present invention significantly improves the operating efficiency and safety of drones in parking lots through innovative designs of charging track 101 and drone 100. Traditional drone charging methods are limited to fixed charging points, which makes charging inconvenient and limits endurance. The charging track 101 in the present invention achieves continuous charging of drones through segmented installation and current conduction design, solving the problem of inconvenient charging of traditional drones, allowing drones to work for a long time in parking lots without having to frequently return to charging stations.

[0034] In addition, the design of the clamping part 12 and the wheeled airbag 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 propeller 112 further enhances the stability of the drone during charging, avoiding the tilt of the fuselage due to the adjustment of the direction of the main power propeller, and ensuring the smooth progress of the charging process.

[0035] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
