Description

TECHNICAL FIELD

[0001] The present application relates to the field of expressway electronic communication technology, and more particularly to a method for preventing misreading of an ETC gantry system. BACKGROUND

[0002] In recent years, intelligent vehicles have become a hot spot in the field of vehicle engineering research and a new driving force for the growth of the automotive industry in the world. Many developed countries have included them in their respective intelligent transportation systems. An intelligent vehicle is a vehicle that is equipped with advanced sensors (radar, cameras), controllers, actuators, and other devices based on ordinary vehicles. Through the vehicle-mounted sensing system and information terminal, it can exchange intelligent information with people, vehicles, roads, and other entities, enabling the vehicle to have intelligent environmental perception capabilities and automatically analyze the safety and danger of vehicle driving. The vehicle-mounted information terminal accurately monitors the vehicle's driving path.

[0003] In order to meet the needs of development and improve traffic efficiency, ETC gantry systems are built in expressway sections to charge passing vehicles. The ETC gantries at expressway entrances and exits are densely arranged, which causes the radio frequency signals of the RSU in the same direction lane of the ETC gantry system to cover the adjacent opposite direction lane, resulting in transactions between the vehicles in the opposite direction lane and the RSU in the same direction lane and causing incorrect charges.

[0004] The main solutions in the prior art to prevent reverse transactions include reducing the signal strength of the RSU to cover only the same direction lane and establishing an RSU radio frequency signal shielding wall in the middle green belt. However, the solution of reducing the signal strength of the RSU can reduce the problem of incorrect charges to some extent, but the effect is limited, and the reduction in signal strength will affect the transaction success rate of vehicles in the same direction lane. Establishing a signal shielding wall in the middle green belt will greatly increase the construction cost of the ETC gantry system and increase the workload and difficulty of subsequent maintenance. SUMMARY

[0042] Example:

[0043] Please see Figs. 1-2 A method for preventing misreading of ETC gantry systems includes the following steps:

[0044] S1, When the vehicle is in motion, the on-board device 1 transmits the data collected by the GPS navigation module 11 and the vehicle sensor module 12 to the on-board device terminal 2.

[0045] S2, the route filtering module 21 on the vehicle equipment terminal 2 filters out possible vehicle driving routes through the positioning of the GPS navigation module 11;

[0046] S3, the vehicle speed comparison module 22 on the vehicle equipment terminal 2 compares the vehicle speed with the driving speed on the possible driving path for filtering. When the vehicle is driving on the highway, the vehicle speed comparison module 22 can filter out the accurate highway route.

[0047] S4, the vehicle Bluetooth module 23 on the vehicle equipment terminal 2 transmits the high-speed route selected in S3 to the vehicle electronic tag 3 with the direction mark code through the vehicle Bluetooth module 23.

[0048] S5, the data storage module 32 on the vehicle electronic tag 3 stores the path data transmitted in S4, and reads the ETC card through the card reader 31;

[0049] S6, when a vehicle enters the highway and passes through the ETC gantry 4, the RSU identification module 41 on the ETC gantry 4 communicates with the information interaction module 33 via short-range communication to read the data in the data storage module 32.

[0050] S7, the driving direction recognition module 43 recognizes the data read in S6 and removes the data read from the opposite lane;

[0051] S8, the communication module 44 inside the ETC gantry 4 transmits the data filtered in S7 to the cloud server 5;

[0052] S9, cloud server 5 identifies the path data in S7 data through path database 51, thereby confirming the vehicle's driving path;

[0053] S10, the charging database 52 calculates the fee based on the identification path in S9 and stores it;

[0054] S11, when the cloud server 5 recognizes the vehicle passing through the ETC gantry 4 at the highway exit, the billing and settlement module 53 summarizes the fees calculated in S10 and outputs them to the bank settlement system to complete the toll collection.

[0055] In this embodiment, by setting up the vehicle-mounted device terminal 2, the route filtering module 21 and the vehicle speed comparison module 22 can calculate the vehicle's driving path using information transmitted from the GPS navigation module 11 and the vehicle sensor module 12. A direction marking code is added to the driving path and transmitted to the vehicle-mounted electronic tag 3 via the vehicle-mounted Bluetooth module 23. This allows the ETC gantry 4 to easily read the vehicle's driving path and direction from the vehicle-mounted electronic tag 3, effectively preventing misreading of the vehicle-mounted electronic tag 3 by ETC gantries 4 in adjacent lanes, thus avoiding reverse toll collection. This ensures accurate toll collection without increasing the construction cost or transaction success rate of the ETC gantry 4, thereby guaranteeing the normal operation of the ETC system. By setting the vehicle-mounted electronic tag 3 to store information from the vehicle-mounted device terminal 2 and read information from the ETC card, the vehicle-mounted device terminal 2 and the vehicle-mounted electronic tag 3 interact with the ETC gantry 4 through the same information interaction module 33, reducing equipment costs. Furthermore, utilizing the vehicle's built-in vehicle-mounted Bluetooth module 23 to interact with the vehicle-mounted electronic tag 3 further reduces manufacturing costs and improves economic efficiency.

[0056] Specifically, a temporary storage module 54 is set up on the cloud server 5, and the temporary storage module 54 stores the cost calculated in S10.

[0057] In this embodiment, the temporary storage module 54 stores the unsettled fees for easy settlement and transmits them to the bank system after settlement, ensuring the normal operation of the system.

[0058] Specifically, the cloud server 5 is equipped with an accounting module 55, which is used to calculate the difference between the direct cost result between the starting point and the end point of the corresponding vehicle's highway route and the statistical record of the toll settlement module 53 in S11.

[0059] In this embodiment, by setting up the accounting module 55 to calculate the cost, the miscalculation caused by the identification errors of the vehicle-mounted equipment terminal 2, the vehicle-mounted electronic tag 3 and the ETC gantry 4 is effectively avoided, thereby improving the accuracy of the toll collection.

[0060] Specifically, the data storage module 32 stores basic vehicle information, including vehicle body color, vehicle model, and license plate number.

[0061] In this embodiment, the accuracy of the data is improved by comparing additional information such as vehicle body color, vehicle model, and license plate number.

[0062] Specifically, the ETC gantry 4 is equipped with a monitoring module 42, which is used to identify basic vehicle information.

[0063] In this embodiment, by identifying basic vehicle information and utilizing a filtering mechanism, the identification speed can be greatly improved while ensuring the accuracy of identification.

[0064] Specifically, cloud server 5 is equipped with cloud database 56, which stores a large amount of information about registered vehicles and users.

[0065] In this embodiment, the information of registered vehicles and users stored in the cloud database 56 can be directly accessed during archiving calculations, which is convenient for management. Furthermore, the information can be archived and stored in the cloud database 56 for easy verification later.

[0066] Specifically, the route filtering module 21 is equipped with a calibration program, which is used to compare the vehicle equipment information transmitted by the GPS navigation module 11 and the vehicle sensor module 12.

[0067] In this embodiment, the calibration procedure can effectively prevent data errors transmitted by the GPS navigation module 11 when the GPS signal is weak in a tunnel, thus ensuring the accuracy of the route selection module 21.

[0068] Specifically, the vehicle-mounted electronic tag 3 can pass through the ETC gantry 4 at the highway entrance when no card is inserted in the card reader 31, and establish a toll account through the vehicle equipment information in the data storage module 32.

[0069] In this embodiment, the data storage module 32 enables vehicles to enter the highway without needing to collect a card at a manual window when the ETC device is not inserted, thereby improving traffic efficiency at the highway entrance, reducing the use of temporary cards, and lowering highway operating costs.

[0070] Specifically, the information interaction module 33 can connect and communicate with the communication equipment set up at the manual payment window, and the manual window can collect payment through the entry storage path data in the data storage module 32.

[0071] In this embodiment, the manual window can also pick up data from the data storage module 32, which facilitates fee settlement and improves the speed of payment.

[0072] Specifically, the vehicle-mounted device terminal 2 can connect and communicate with the vehicle-mounted electronic tag 3 through the vehicle-mounted WIFI system.

[0073] In this embodiment, the use of the vehicle WIFI system can avoid the vehicle electronic tag 3 occupying the vehicle Bluetooth module 23, and ensure the normal operation of devices in the vehicle that need to connect to the vehicle Bluetooth.

[0074] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
