Description

Technical Field

[0001] The present invention belongs to the technical field of parking fee collection, and in particular relates to a parking fee collection system and method thereof that combines an ETC with a low-altitude aircraft. Background Art

[0002] As a modern toll collection method, the Electronic Toll Collecting System (ETC) has been widely used in toll management of highways and bridges. The system realizes the non-stop toll collection of vehicles through wireless communication and information exchange between the on-board unit (OBU) installed on the vehicle and the roadside unit (RSU) on the lane of the toll station. The ETC system is mainly composed of a vehicle automatic identification system, a central management system and other auxiliary facilities. Among them, the vehicle automatic identification system includes components such as the on-board unit, the roadside unit and the loop sensor. The on-board unit stores the vehicle identification information and is usually installed on the front windshield of the vehicle, while the roadside unit is installed next to the toll station, and the loop sensor is buried under the lane. When a vehicle passes through a toll station, the loop sensor first senses the presence of the vehicle, and then the roadside unit sends an inquiry signal. The on-board unit responds and conducts two-way communication and data exchange. The central management system compares the obtained vehicle identification information with the information in the database, and then controls the corresponding actions of the management system, such as deducting tolls from the prepaid account. With the continuous development of ETC technology, its application scope is becoming increasingly wide. However, in traditional ETC systems, RSU can usually only be fixed on the roadside and is mainly used in highway toll collection systems. It has limited adaptability to other scenarios.

[0003] In order to expand the application scope of ETC technology, the Chinese patent document with announcement number CN202976217U proposed an intelligent parking lot management system based on ETC technology. The system includes a server unit, an entrance unit and an exit unit. The entrance and exit units are equipped with ETC readers, which are connected to the management computer through a controller, and the management computers of the entrance and exit units are connected to the server through a switch. In addition, the entrance unit is also equipped with a ticket box machine, a voice prompt machine, a display screen, an entrance camera, a gate and a ground sensor to handle foreign vehicles that are not equipped with ETC electronic tags. The exit unit is equipped with a corresponding voice prompt machine, a display screen, an exit camera, a gate and a ground sensor. This intelligent parking lot management system can provide efficient, intelligent and safe parking management services. However, the system still has some shortcomings: (1) The parking lot management system is mainly suitable for closed parking lot environments. A gantry can be set at the entrance and exit to carry the ETC sensing equipment, thereby realizing ETC automatic sensing charging. For open roadside parking scenarios, it is difficult to implement ETC parking fees due to the limited sensing range of roadside units; (2) Due to the widespread mixing of ETC vehicles and non-ETC vehicles in the current traffic system, it is difficult to charge roadside parking fees for all vehicles solely relying on the ETC charging system, and manual intervention is often required to paste collection slips; (3) Since the parking fee system usually settles based on the time from when the vehicle enters the parking space to when it leaves the parking space, if the user forgets to pay after leaving the parking space, it will result in parking arrears, which will in turn affect the company's capital return.

[0004] In summary, although ETC technology has demonstrated the advantages of high efficiency and convenience in highway toll collection and closed parking lot management, the existing ETC toll collection system and its extended applications still have many limitations when facing open roadside parking scenarios. Especially in complex scenarios such as mixed traffic flow, open parking environment, and diverse user payment habits, it is difficult for existing technologies to fully meet the needs of parking fee management. Therefore, in view of the problems existing in the existing technologies, it is urgent to provide an ETC combined with low-altitude aircraft parking payment system and method, so as to realize automatic identification and efficient charging of all vehicles, while improving the user experience and the operational efficiency of enterprises.

[0015] As a further improvement of the above solution, the mechanical claw includes a mounting seat, one end of which is fixed to the drone body, and the other end is provided with a plurality of rotating arms connected in sequence, and each rotating arm is provided with an independent driving source.

[0021] As a further improvement of the above solution, the drone is also provided with a camera module, which is configured to photograph parked vehicles in roadside parking spaces for evidence collection.

[0022] A parking fee payment method for ETC combined with a low-altitude aircraft is applied to the parking fee payment system for ETC combined with a low-altitude aircraft as described above, and comprises the following steps:

[0023] S1: A parked vehicle enters a roadside parking space, the monitoring module monitors the parked vehicle, and activates the timing module to count the parking time of the parked vehicle; the timing module has multiple timing thresholds built in according to the parking time, and when the parking time reaches the timing threshold, the parking timing device feeds back to the control assembly, and the control assembly sends a payment instruction to the aircraft payment device;

[0024] S2: After the aircraft payment device receives the payment instruction, the drone flies to the parked vehicle to be paid, and the roadside module on the drone attempts to exchange information with the parked vehicle and issues a deduction instruction;

[0025] S3: The drone activates the payment printing module to print a corresponding payment receipt based on whether the parked vehicle responds to the fee deduction instruction, and clamps the payment receipt between the windshield and wiper of the parked vehicle through the mechanical claw.

[0026] Beneficial effects of the present invention:

[0027] (1) Solve the ETC charging problem in open roadside parking scenarios: Traditional parking lot management systems mainly rely on closed parking lot environments and ETC sensing devices on the gantry to achieve automatic charging. However, in open roadside parking scenarios, due to the limited sensing range of the roadside module, the ETC automatic charging system is difficult to effectively cover. The ETC of the present invention is combined with the parking payment system of low-altitude aircraft, which effectively solves this problem by setting columns in roadside parking spaces and deploying parking timing devices, aircraft payment devices and control assemblies on the columns. The system can accurately monitor parked vehicles and realize remote deductions and information exchange through drones, without relying on fixed ETC sensing equipment, so it is suitable for various open roadside parking scenarios, improving the flexibility and coverage of the charging system.

[0028] (2) Realize mixed charging of ETC vehicles and non-ETC vehicles: In the current traffic system, the mixed traffic of ETC vehicles and non-ETC vehicles is common. The traditional ETC charging system is difficult to charge all vehicles effectively, and often requires manual intervention to paste collection slips, which not only increases labor costs but also reduces charging efficiency. The system of the present invention exchanges information with parked vehicles through the roadside module on the drone and issues deduction instructions. For ETC vehicles, as long as their on-board equipment supports information interaction, automatic deduction can be achieved. For non-ETC vehicles that do not support information interaction, the drone can also print payment receipts and clamp them between the vehicle's windshield and wipers, realizing mixed charging for all parked vehicles, greatly improving the versatility and efficiency of the charging system.

[0029] (3) Solve the problem of parking arrears and improve capital return: Traditional parking fee collection systems usually settle accounts based on the time from when the vehicle enters the parking space to when it leaves the parking space. However, if the user forgets to pay after leaving the parking space, it will lead to parking arrears, which will in turn affect the company's capital return. The system of the present invention uses a drone to perform payment reminders and deductions after the parking time reaches the timing threshold, effectively avoiding the situation where users forget to pay. At the same time, the payment receipts printed by the drone also serve as payment vouchers, which are convenient for users to check and make up the fees. This method of instant deduction and voucher printing not only reduces the phenomenon of parking arrears, but also improves the company's capital return speed and operational efficiency.

[0047] 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.

[0048] like Figure 1-Figure 5 As shown, an ETC combined with a low-altitude aircraft parking fee payment system is used to collect time-based fees for parked vehicles in roadside parking spaces; at least one column 1 is provided on one side of the roadside parking space, and a parking timer 11, an aircraft fee payment device 2 and a control assembly (not shown) are provided on the upper part of the column 1; the control assembly is respectively connected to the parking timer 11 and the aircraft fee payment device 2 for communication;

[0049] The parking timing device 11 includes a monitoring module and a timing module; the monitoring module is used to monitor the parked vehicles entering the roadside parking space, and mobilize the timing module to individually time the parking of the parked vehicles; the timing module has multiple timing thresholds built in according to the parking time, and when the parking time reaches the first timing threshold, the parking timing device 11 feeds back to the control assembly, and the control assembly sends a payment instruction to the aircraft payment device 2;

[0050] The aircraft payment device 2 includes a landing platform 21 and a drone 22; the landing platform 21 is arranged on the column 1, and is used to provide a parking space for the drone 22, as well as charging and energy supply; the drone 22 includes a drone body 23, and a roadside module 24 (i.e., RSU) arranged on the drone body 23, a payment printing module 25, and a mechanical claw 26; when the aircraft payment device 2 receives the payment instruction, the drone 22 flies to the parked vehicle to be paid, and the roadside module 24 on the drone 22 attempts to exchange information with the parked vehicle and issues a deduction instruction;

[0051] The drone 22 activates the payment printing module 25 to print a corresponding payment receipt according to whether the parked vehicle responds to the deduction instruction, and clamps the payment receipt between the windshield 3 and the wiper 4 of the parked vehicle through the mechanical claw 26.

[0052] In this embodiment, if the parked vehicle responds to the deduction instruction, the parked vehicle is an ETC vehicle; the ETC vehicle is provided with at least an on-board module (i.e., OBU), which is activated after receiving the microwave signal emitted by the roadside module 24 and feeds back the vehicle information to the roadside module 24; the roadside module 24 associates the ETC account of the parked vehicle and issues a deduction instruction based on the vehicle information, and the on-board unit responds to the deduction; the vehicle information includes the license plate number and ETC account of the parked vehicle.

[0053] The payment receipt printed by the payment printing module 25 is attached with a QR code, and the QR code is associated with the deduction information of the parked vehicle; if the parked vehicle does not respond to the deduction instruction, the parked vehicle is a non-ETC vehicle; the non-ETC vehicle may not be equipped with an on-board module, or the OBU is not enabled, the OBU is illegally disassembled, the OBU is reported lost, the card is reported lost, the card is disabled, the balance is insufficient, etc. The payment receipt printed by the payment printing module 25 is attached with a QR code, and the QR code is associated with the arrears information of the parked vehicle. Through the microwave signal interaction between the on-board module and the roadside module 24, the ETC vehicle can quickly respond to the deduction instruction and complete the automatic deduction of the fee, providing ETC users with a more convenient and efficient parking payment experience. When the parked vehicle does not respond to the deduction instruction, the system can automatically determine that it is a non-ETC vehicle, and print out a QR code payment receipt containing the arrears information through the payment printing module 25. The owner only needs to scan the QR code to easily complete the payment, avoiding the tediousness and inconvenience of manual intervention.

[0054] Traditional ETC toll collection systems are difficult to charge all vehicles effectively, and often require manual intervention to paste collection slips, which not only increases labor costs but also reduces toll collection efficiency. The system of the present invention exchanges information with parked vehicles through the roadside module 24 on the drone 22 and issues deduction instructions. For ETC vehicles, as long as their on-board equipment supports information interaction, automatic deduction can be achieved. For non-ETC vehicles that do not support information interaction, the drone 22 can also print payment receipts and clamp them between the vehicle windshield 3 and the wiper 4, realizing mixed charging for all parked vehicles, greatly improving the versatility and efficiency of the toll collection system.

[0055] In this embodiment, if the parked vehicle is an ETC vehicle, when the parking time reaches the next timing threshold, the drone 22 flies to the vehicle to be parked and performs the deduction operation; the deduction information associated with the QR code on the payment receipt is updated in real time; if the parked vehicle is a non-ETC vehicle, when the parking time reaches the next timing threshold, the drone 22 does not perform the deduction operation; the arrears information associated with the QR code on the payment receipt is updated in real time. In this embodiment, the drone 22 performs payment reminders and deduction operations after the parking time reaches the timing threshold, effectively avoiding the situation where the user forgets to pay. At the same time, the payment receipt printed by the drone 22 is also used as a payment voucher, which is convenient for users to check and make up the fees. This method of instant deduction and voucher printing not only reduces the phenomenon of parking arrears, but also improves the capital return speed and operational efficiency of the enterprise.

[0056] In this embodiment, the mechanical claw 26 includes a mounting base 261, one end of which is fixed to the drone body 23, and the other end is provided with a plurality of rotating arms 262 connected in sequence, each rotating arm 262 is provided with an independent driving source 263, and the driving source 263 is a motor.

[0057] In this embodiment, the payment printing module 25 is provided on the last rotating arm 262, and the payment printing module 25 is provided with a bill outlet 251, and the payment bill is output from the bill outlet 251; two flat plates 27 are extended along the bill outlet 251, and a conveying channel 271 for the payment bill to pass through is provided between the two flat plates 27; the ends of the two flat plates 27 are connected with an upper clamping plate 281 and a lower clamping plate 282, respectively, wherein the upper clamping plate 281 is driven by a driving unit 283, and the upper clamping plate 281 rotates around its connection so that the two clamping plates abut or separate, and the conveying channel 271 is closed or opened accordingly; the driving unit 283 is an electric push rod, the seat of the electric push rod is fixedly connected to the flat plate 27, and the rod head of the electric push rod is connected to the upper clamping plate 281 in a transmission manner. In this embodiment, a plurality of rotating rollers 272 are provided between the two flat plates 27, and the payment bill is conveyed by the power of the rotating rollers 272.

[0058] After the payment printing module 25 prints the corresponding payment receipt, the upper clamping plate 281 and the lower clamping plate 282 of the mechanical claw 26 are initially abutted, and the upper clamping plate 281 and the lower clamping plate 282 of the mechanical claw 26 are jointly inserted into the gap between the windshield 3 and the wiper 4; the upper clamping plate 281 is driven by the driving unit 283 to open the conveying channel 271 and lift the wiper 4; at this time, the payment receipt is output from the conveying channel 271, and the mechanical claw 26 is withdrawn, so that the payment receipt is pressed against the windshield 3 by the wiper 4.

[0059] It should be noted that the traditional parking fee system usually settles according to the time from when the vehicle enters the parking space to when it leaves the parking space. However, if the user forgets to pay after leaving the parking space, it will lead to parking arrears, which will affect the capital return of the enterprise. In order to improve the efficiency of capital return, it is necessary to place the payment slip to achieve the reminder function. Generally, manual intervention is required to place the payment slip. The parking fee payment system realizes the automatic delivery of the payment slip by the drone 22 equipped with the mechanical claw 26, which greatly improves the delivery efficiency and accuracy. Compared with manual placement, the drone 22 can quickly reach the designated location, avoiding the delay of the delivery of the slip due to insufficient manpower or traffic congestion, and also reduces the possibility of human error. Secondly, the mechanical claw 26 is exquisitely designed and powerful. Through the rotating arm 262 connected in sequence by multiple sections and the independent driving source 263, the mechanical claw 26 can flexibly adjust the posture and accurately deliver the payment slip into the gap between the vehicle windshield 3 and the wiper 4. This design not only ensures the stable placement of the slip, but also avoids the loss or damage of the slip due to improper placement. In addition, the collaborative work of the payment printing module 25 and the mechanical claw 26 also greatly improves the user experience. After the payment receipt is printed, it can be immediately delivered to the vehicle through the mechanical claw 26 without manual intervention. At the same time, the design of the upper clamping plate 281 and the lower clamping plate 282 allows the receipt to be output smoothly and fixed on the windshield 3, which is convenient for the owner to check and avoids the risk of the receipt being blown off or lost by the wind.

[0060] In this embodiment, the monitoring module is provided with an image acquisition unit for capturing images of parked vehicles and obtaining the license plate number of the parked vehicle from the images; the timing module establishes or classifies a corresponding timing file according to the license plate number of the parked vehicle, and the timing file includes the license plate number of the parked vehicle, the parking space number, the parking start time, the parking end time, and the historical parking record.

[0061] In this embodiment, the upper part of the column 1 is also provided with a lighting module 5, a solar panel 6 and an energy storage battery; the solar panel 6 is connected to the energy storage battery, and the energy storage battery is electrically connected to the lighting module 5 and the landing platform 21 respectively; the landing platform 21 is provided with a wireless charging module, and the wireless charging module is used to charge and supply energy to the drone 22. Fast charging is achieved through the wireless charging module, which effectively extends the battery life of the drone 22 and solves the problem of insufficient battery life. At the same time, the column 1 is also provided with a lighting module 5, such as a lamp head, which can realize the integration of street lamps and provide lighting needs.

[0062] In this embodiment, the drone 22 is also provided with a camera module 231, and the camera module 231 is configured to photograph parked vehicles in roadside parking spaces for evidence collection. When the drone 22 flies to the parked vehicle to be paid, the drone 22 detours along an arc line with the parked vehicle as the center, and the camera module 231 detours and photographs multiple points in its radial direction on the detour trajectory to obtain panoramic evidence photos; the camera range of the panoramic evidence photos extends from the front of the parked vehicle to the rear of the parked vehicle. The drone 22 is equipped with a camera module 231, which can detour and photograph the parked vehicle to obtain panoramic evidence photos. The camera range of the panoramic evidence photos extends from the front of the parked vehicle to the rear of the parked vehicle, and associates the parking space, the parked vehicle and the surrounding environment to form a complete chain of evidence, which improves the accuracy and reliability of evidence collection and reduces the distortion problem caused by photo stitching.

[0063] Through the above scheme, in a specific application, a parking fee payment method for ETC combined with a low-altitude aircraft includes the following steps:

[0064] S1: A parked vehicle enters a roadside parking space, the monitoring module monitors the parked vehicle, and activates the timing module to count the parking time of the parked vehicle; the timing module has multiple timing thresholds built in according to the parking time, when the parking time reaches the timing threshold, the parking timing device 11 feeds back to the control assembly, and the control assembly sends a payment instruction to the aircraft payment device 2;

[0065] S2: After the aircraft payment device 2 receives the payment instruction, the drone 22 flies to the parked vehicle to be paid, and the roadside module 24 on the drone 22 attempts to exchange information with the parked vehicle and issues a deduction instruction;

[0066] S3: The drone 22 activates the payment printing module 25 to print a corresponding payment receipt according to whether the parked vehicle responds to the deduction instruction, and clamps the payment receipt between the windshield 3 and the wiper 4 of the parked vehicle through the mechanical claw 26.

[0067] The parking fee payment system realizes remote deduction and information exchange through the drone 22, without relying on fixed ETC sensing equipment, and is therefore applicable to various open roadside parking scenarios; in addition, the drone 22 performs payment reminders and deduction operations when the parking time reaches the timing threshold, effectively preventing users from forgetting to pay.

[0068] According to the disclosure and teaching of the above description, those skilled in the art to which the present invention belongs may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the invention should also fall within the scope of protection of the claims of the present invention.
