Description

Technical Field

[0001] This invention relates to the field of highway non-stop toll collection technology, and in particular to a highway non-stop toll collection method and system based on mobile phone Bluetooth. Background Technology

[0002] ETC (Electronic Toll Collection) systems achieve non-stop toll collection through wireless communication and information exchange between onboard units installed in vehicles and antennas installed in toll booth lanes. ETC systems require users to install an On-Board Unit (OBU) in their vehicles. For users without an OBU, current highway toll collection uses CPC cards. A CPC card is issued to the user for on-the-go toll calculation, and the user returns the CPC card at the exit for mobile payment or cash payment. Using CPC cards requires stopping to pay, which is slow, and also suffers from high CPC management costs and difficulties in allocation. There is an urgent need for a technology to solve the problem of convenient highway toll collection for users without OBU devices. Summary of the Invention

[0003] In view of this, embodiments of the present invention provide a method and system for non-stop toll collection on highways based on mobile phone Bluetooth, so as to eliminate or improve one or more defects existing in the prior art and solve the problem of conveniently completing highway toll collection for users who have not installed OBU devices.

[0004] One aspect of the present invention provides a method for highway non-stop toll collection based on mobile phone Bluetooth. The method is executed on a mobile terminal deployed on a passing vehicle, the mobile terminal being equipped with a first Bluetooth module. The method includes the following steps:

[0005] The first Bluetooth module connects to the second Bluetooth module of the entrance toll station and exchanges pre-registered certificates for identity authentication. After successful authentication, the vehicle information of the passing vehicle is read and sent to the entrance toll station, so that the entrance toll station can compare the first license plate information in the vehicle driving information with the second license plate information recognized by the local camera. If they match, the entrance toll station receives the entrance information written by the entrance toll station.

[0006] Receive gantry information continuously broadcast by the passing gantry via a third Bluetooth module, the gantry information including timestamp, gantry number, gantry location, rate, and signature information; send the signature information to the backend for verification, and save the gantry information if the verification is successful;

[0007] The first Bluetooth module connects to the fourth Bluetooth module at the exit toll station and exchanges pre-registered certificates for identity authentication. After successful authentication, the system reads and sends vehicle driving information to the exit toll station. The vehicle driving information includes third license plate information, vehicle model information, and information about all passing gantries. The exit toll station then forwards the vehicle driving information to the backend to request billing. After the vehicle enters the station, the exit toll station compares the third license plate information with the fourth license plate information recognized by the local camera. If they match, a payment order is generated to request payment from the backend, and the exit record is uploaded to the backend storage.

[0008] In some embodiments, after the entrance toll station compares the first license plate information in the vehicle driving information with the second license plate information recognized by the local camera, it further includes: if they are inconsistent, generating a prompt message and switching to a manual toll collection process;

[0009] After comparing the third license plate information with the fourth license plate information recognized by the local camera, the exit toll station further includes: if they do not match, generating a prompt message and switching to a manual toll collection process.

[0010] In some embodiments, the method further includes:

[0011] The first Bluetooth module, the second Bluetooth module, the third Bluetooth module, and the fourth Bluetooth module communicate with each other via multi-channel Bluetooth.

[0012] The second, third, and fourth Bluetooth modules also dynamically adjust the Bluetooth power based on the signal strength received by the first Bluetooth module.

[0013] In some embodiments, before connecting the first Bluetooth module to the second Bluetooth module of the entrance toll station and exchanging pre-registered certificates for identity authentication, the method further includes: receiving a first challenge value random number sent by the entrance toll station, generating a first response value based on the random number challenge mechanism, and returning it to the entrance toll station for verification;

[0014] Before connecting the fourth Bluetooth module of the exit toll station via the first Bluetooth module and exchanging pre-registered certificates for identity authentication, the method further includes: receiving a second challenge value random number sent by the exit station, generating a first response value based on the random number challenge mechanism, and sending it back to the entrance toll station for verification.

[0015] In some embodiments, after receiving the entry information written by the entry toll station, the method further includes: sending an entry information writing success feedback message to the entry toll station, so that the entry toll station can send the entry record to the backend as a log for querying and tracing based on the entry information writing success feedback message.

[0016] In some embodiments, the signature information is obtained by calculating a hash value from the timestamp, the gantry number, the gantry location, and the rate, and then encrypting the hash value using the private key in a pre-generated key pair.

[0017] In some embodiments, after sending the signature information to the backend for verification, the method further includes:

[0018] If the verification fails, discard the currently received gantry information and add a gantry information missing marker to the generated vehicle driving information.

[0019] On the other hand, the present invention also provides a high-speed non-stop toll collection system based on mobile phone Bluetooth. The system includes an entrance toll station, an exit toll station, multiple gantry systems, and a mobile terminal carried or deployed on passing vehicles. The entrance toll station, the exit toll station, the gantry system, and the mobile terminal are all equipped with Bluetooth modules. The entrance toll station, the exit toll station, the gantry system, and the mobile terminal are connected to the back-end subsystem via wired or wireless connection.

[0020] The mobile terminal executes the aforementioned high-speed non-stop toll collection method based on mobile phone Bluetooth by loading a computer program.

[0021] On the other hand, the present invention also provides a computer-readable storage medium having a computer program / instructions stored thereon, which, when executed by a processor, implements the steps of the above-described method.

[0022] On the other hand, the present invention also provides a computer program product, including a computer program / instructions, which are executed by a processor using the steps of the above-described method.

[0023] The beneficial effects of the present invention are at least as follows:

[0024] The present invention describes a high-speed non-stop toll collection method and system based on mobile phone Bluetooth. It uses Bluetooth communication deployed in the entrance lane, gantry system, exit lane and mobile terminal to collect and record vehicle information, entrance information and passing gantry information, and performs data aggregation and toll transaction in the exit lane. In the absence of ETC devices and composite toll cards, it can achieve efficient toll transaction and improve traffic efficiency.

[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this invention are used to explain the invention, but are not intended to limit the invention.

[0033] It should also be noted that, in order to avoid obscuring the invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the invention are shown in the accompanying drawings, while other details that are not closely related to the invention are omitted.

[0034] It should be emphasized that the term "including / comprises" as used herein refers to the presence of a feature, element, step, or component, but does not exclude the presence or addition of one or more other features, elements, steps, or components.

[0035] It should also be noted that, unless otherwise specified, the term "connection" in this article can refer not only to a direct connection, but also to an indirect connection involving an intermediary.

[0036] In highway toll collection systems, the toll collection process mainly consists of two parts: accurate toll calculation, which involves accurately recording the vehicle's travel route and calculating the toll based on that route; and payment, where users pay the toll using cash, bank cards, or mobile payment. Currently, highways use two technologies for toll collection: ETC (Electronic Toll Collection) and CPC (Combined Toll Card). ETC allows for non-stop toll collection, but users need to purchase and install an on-board unit (OBU) before traveling. The MTC (Medium-Terminal Toll Collection) scheme involves obtaining a CPC card at the entrance, using the CPC card to interact with the gantry RSU (Roadside Unit) for toll calculation during the journey, and returning the CPC card at the exit to pay using mobile payment or cash. This technology requires stopping to complete the toll collection, and the allocation and management of CPC cards incurs high operating costs. ETC and CPC cards use the same toll calculation method: when a vehicle passes through the highway toll gantry, the corresponding toll information is written to the OBU or CPC card; at the exit, the toll information is accumulated to calculate the final toll. ETC payment is done by linking to a bank account in the backend; a transaction record is generated after exiting the highway, and then submitted to the bank for deduction. CPC card payment allows you to pay tolls using mobile payment or cash after parking at the exit.

[0037] With the widespread adoption of smartphones today, using them for non-stop toll collection on highways represents a future trend. This eliminates the need for users to install new equipment while enabling rapid payment and communication. All smartphones possess Bluetooth connectivity, allowing communication between the phone and roadside equipment for non-stop toll collection. This benefits users while reducing management costs for highway operators.

[0038] Bluetooth device A is installed at highway entrances and exits. This device can communicate with mobile phones via Bluetooth and can locate the phones. Bluetooth device B is installed at highway ETC gantries. This device continuously broadcasts information about the current gantry. When a vehicle passes through a gantry, it receives the broadcast information, and the mobile phone records the gantry information along the route to calculate the toll. The gantry Bluetooth broadcast can also serve as an information dissemination channel, publishing downstream traffic information to users' mobile phones to draw their attention and improve driving safety. Users download the highway toll collection APP or mini-program, register, and bind their mobile payment account. The APP will interact with the roadside Bluetooth devices to realize functions such as route recording, toll calculation, and back-end payment.

[0039] Specifically, this invention provides a method for non-stop toll collection on highways based on mobile phone Bluetooth. The method is executed on a mobile terminal deployed on a passing vehicle, and the mobile terminal is equipped with a first Bluetooth module, such as... Figure 1As shown, the method includes the following steps S101 to S103:

[0040] Step S101: Connect the first Bluetooth module to the second Bluetooth module of the entrance toll station and exchange pre-registered certificates for identity authentication. After successful authentication, read the vehicle information of the passing vehicle and send it to the entrance toll station so that the entrance toll station can compare the first license plate information in the vehicle driving information with the second license plate information recognized by the local camera. If they match, receive the entrance information written by the entrance toll station.

[0041] Step S102: Receive gantry information continuously broadcast by the passing gantry via a third Bluetooth module. The gantry information includes timestamp, gantry number, gantry location, rate, and signature information. Send the signature information to the backend for verification. If the verification is successful, save the gantry information.

[0042] Step S103: Connect the first Bluetooth module to the fourth Bluetooth module of the exit toll station and exchange pre-registered certificates for identity authentication. After successful authentication, read the vehicle driving information and send it to the exit toll station. The vehicle driving information includes the third license plate information, vehicle model information, and gantry information of all passing gantries, so that the exit toll station can forward the vehicle driving information to the background to request tolling. After the vehicle enters the station, the exit toll station compares the third license plate information with the fourth license plate information recognized by the local camera. If they match, a payment order is generated to request payment from the background, and the exit record is uploaded to the background storage.

[0043] The hardware foundation for executing steps S101 to S103 is a non-stop toll collection system deployed on highways, including entrance toll stations, gantry systems, and exit toll stations. Compared to traditional deployment methods, the entrance toll stations, gantry systems, and exit toll stations in this invention are all equipped with Bluetooth modules, providing a hardware foundation for non-stop toll collection transactions using mobile terminals.

[0044] In some embodiments, the method further includes: the first Bluetooth module, the second Bluetooth module, the third Bluetooth module and the fourth Bluetooth module interact with each other using a multi-channel Bluetooth communication method; even if one channel is interfered with, communication can still be maintained through a backup channel to avoid losing important data.

[0045] The second, third, and fourth Bluetooth modules dynamically adjust their Bluetooth power based on the signal strength received by the first Bluetooth module. This adjustment of Bluetooth power according to different scenarios (such as high-speed driving or traffic congestion) ensures a stable connection under various conditions. Simultaneously, the connection quality can be monitored by signal strength, and connection strategies can be automatically adjusted accordingly.

[0046] Furthermore, mobile devices typically have limited power, especially during extended use. Introducing Bluetooth Low Energy (BLE) technology reduces the power consumption of the Bluetooth module while maintaining transmission distance and speed, thus extending the battery life of mobile devices.

[0047] In step S101, when a vehicle arrives at the entrance toll station, the second Bluetooth module of the entrance toll station establishes a connection with the first Bluetooth module of the mobile terminal, followed by certificate exchange and authentication, specifically including:

[0048] 1. Certificate and Key Preparation

[0049] The first Bluetooth module of the mobile terminal needs to generate its own public-private key pair and digital certificate. The certificate should be issued by a trusted Certificate Authority (CA) and contain the mobile terminal's identity information and public key. The second Bluetooth module of the tollbooth also needs to generate its own public-private key pair and obtain a digital certificate issued by a CA. This certificate should contain the tollbooth's identity information and public key.

[0050] 2. Bluetooth pairing and key exchange

[0051] During connection establishment, Bluetooth devices typically use Secure Simple Pairing (SSP) or Bluetooth LE security protocols to exchange keys. If Bluetooth LE (Bluetooth Low Energy) is used, Public Key Cryptography (PKC) may be employed for key exchange. Bluetooth devices use the ECDH (Elliptic Curve Diffie-Hellman) algorithm to securely exchange encryption keys.

[0052] 3. Two-way certificate exchange

[0053] The second Bluetooth module sends its digital certificate to the first Bluetooth module: The second Bluetooth module will send the digital certificate containing its public key and identity information to the first Bluetooth module on the mobile phone.

[0054] The mobile terminal sends its digital certificate to the second Bluetooth module of the entrance toll station device via the first Bluetooth module: the mobile terminal also sends its public key and identity information digital certificate to the entrance toll station via Bluetooth.

[0055] 4. Certificate Verification

[0056] Verify the certificate at the mobile terminal entry toll station; check the certificate signature to ensure it was issued by a trusted CA. Verify the certificate validity period to ensure it is within the validity period. Check the certificate revocation status, which can be confirmed via CRL (Certificate Revocation List) or OCSP (Online Certificate Status Protocol).

[0057] The tollbooth at the entrance verifies the mobile terminal's certificate, checks the certificate signature to ensure it was issued by a trusted CA, verifies the certificate's validity period, and checks its revocation status, which can be verified using CRL or OCSP.

[0058] 5. Establish encrypted communication

[0059] Once the certificate verification is successful, the mobile terminal and the tollbooth can generate a shared session key for encrypting subsequent communications. This session key is used to encrypt all subsequent data to ensure data security during transmission.

[0060] 6. Data exchange and authentication

[0061] After a secure connection is established, the mobile terminal and the tollbooth can exchange data, such as writing vehicle and entry information. All communication data is transmitted through an encrypted channel to prevent theft or tampering.

[0062] Furthermore, after entering the toll station, vehicles are also identified by a local camera, and their license plate information is compared with that read via Bluetooth. Only if they match are allowed to pass. In some embodiments, after comparing the first license plate information from the vehicle's driving information with the second license plate information identified by the local camera, the toll station further includes: if they do not match, generating a prompt message and switching to a manual toll collection process.

[0063] In step S102, when a vehicle is using the gantry system, it receives gantry information broadcast by the gantry system for segmented tolling. In some embodiments, the signature information is obtained by calculating a hash value from the gantry pair timestamp, gantry number, gantry location, and toll rate, and then encrypting the hash value using the private key in a pre-generated public key pair.

[0064] In step S103, when a vehicle arrives at the exit toll station, the first Bluetooth module and the fourth Bluetooth module establish a connection and exchange certificates for identity authentication. The specific process can be found in the description of step S101 above. After authentication, the mobile terminal sends vehicle driving information generated during the journey to the fourth Bluetooth module via the first Bluetooth module. This information includes the third license plate information, vehicle model information, and gantry information of all passing gantries. The exit toll station queries the backend for billing information. The exit toll station uses a camera to collect the fourth license plate information of the passing vehicle and compares it with the third license plate information. If the comparison matches, a payment order is generated, and the backend is requested to make payment. Simultaneously, the exit record is uploaded, and the barrier is raised to allow passage.

[0065] Furthermore, after comparing the third license plate information with the fourth license plate information recognized by the local camera, the exit toll station also includes: if they do not match, generating a prompt message and switching to the manual toll collection process.

[0066] In some embodiments, before connecting the second Bluetooth module of the entrance toll station via the first Bluetooth module and exchanging pre-registered certificates for identity authentication in step S101, the method further includes step S201: receiving a first challenge value random number sent by the entrance toll station, generating a first response value based on the random number challenge mechanism, and returning it to the entrance toll station for verification.

[0067] In step S103, before connecting the fourth Bluetooth module of the exit toll station through the first Bluetooth module and exchanging pre-registered certificates for identity authentication, the method further includes step S202: receiving a second challenge value random number sent by the exit station, generating a first response value based on the random number challenge mechanism, and returning it to the entrance toll station for verification.

[0068] In some embodiments, after receiving the entry information written by the entry toll station in step S101, the method further includes step S203: sending entry information writing success feedback information to the entry toll station, so that the entry toll station can send the entry record to the background as a log based on the entry information writing success feedback information for querying and tracing.

[0069] In some embodiments, after sending the signature information to the background for verification in step S102, step S204 is further included: if the verification fails, discard the currently received gantry information and add a gantry information missing mark to the generated vehicle driving information.

[0070] During subsequent billing, for road segments with missing markers, the complete travel path is restored by path fitting.

[0071] On the other hand, the present invention also provides a high-speed non-stop toll collection system based on mobile phone Bluetooth. The system includes an entrance toll station, an exit toll station, multiple gantry systems, and a mobile terminal carried or deployed on passing vehicles. The entrance toll station, the exit toll station, the gantry system, and the mobile terminal are all equipped with Bluetooth modules. The entrance toll station, the exit toll station, the gantry system, and the mobile terminal are connected to the back-end subsystem via wired or wireless connection.

[0072] The mobile terminal executes the high-speed non-stop toll collection method based on mobile phone Bluetooth described in steps S101 to S103 above through a computer program.

[0073] This invention also provides a computer-readable storage medium storing a computer program thereon, which, when executed by a processor, implements the steps of the aforementioned edge computing server deployment method. The computer-readable storage medium can be a tangible storage medium, such as random access memory (RAM), main memory, read-only memory (ROM), electrically programmable ROM, electrically erasable programmable ROM, registers, floppy disks, hard disks, removable storage disks, CD-ROMs, or any other form of storage medium known in the art.

[0074] On the other hand, the present invention also provides a computer program product, including a computer program / instructions, which are executed by a processor using the steps of the above-described method.

[0075] The present invention will be described below with reference to a specific embodiment:

[0076] This embodiment describes a method for non-stop toll collection on highways based on mobile phone Bluetooth, which uses short-range wireless communication between the mobile phone and roadside facilities to achieve non-stop toll collection on highways.

[0077] The system consists of four parts: a mobile terminal, lane terminals, a gantry system, and a back-end system. The mobile terminal serves as the user interaction portal, representing the user's identity. The lane terminals are the toll station entrance and exit systems, controlling the flow of vehicles entering and exiting the highway and enabling toll collection. The gantry system is deployed on the highway, and the back-end system provides data aggregation and business support.

[0078] Before using the service, users should download the highway toll collection app or mini-program, complete the registration, and bind their mobile payment account.

[0079] Bluetooth device A is installed at the entrance of the highway toll station. When a vehicle enters the toll station, the Bluetooth device locates the mobile phone and establishes a Bluetooth connection. After the Bluetooth device and mobile phone exchange certificates and authenticate each other, the Bluetooth device reads the vehicle information associated with the mobile phone and maintains the Bluetooth connection. After completion, the Bluetooth device transmits the vehicle information to the lane system. When the vehicle reaches the license plate recognition area, the camera recognizes the license plate and compares it with the vehicle information read by the Bluetooth device. If the comparison matches, the entry information is written to the mobile phone, and then the entry record is uploaded to the backend, and the barrier is immediately raised to allow passage. The toll station entry process is as follows: Figure 2 As shown.

[0080] Bluetooth device B is installed in the gantry system. The Bluetooth device continuously broadcasts information about the gantry, including timestamp, gantry number, gantry location, toll rate, and information signature value. The gantry information is signed using the private key issued by the Bluetooth device to obtain the information signature value, ensuring the information cannot be forged. When a vehicle passes through the Bluetooth communication zone of the gantry, the mobile phone receives the broadcast information and verifies the signature in the background. Upon successful verification, the record is saved for calculating communication fees at the exit. The gantry processing flow is as follows: Figure 3 As shown.

[0081] Bluetooth device A is installed at the highway toll station exit. When a vehicle enters the toll station entrance, the Bluetooth device locates the mobile phone and establishes a Bluetooth connection. After the Bluetooth device and mobile phone exchange and authenticate certificates, the Bluetooth device reads the vehicle's driving information from the mobile phone and uses this information to request the backend to calculate the fee online. After completion, the Bluetooth connection is maintained. When the vehicle reaches the license plate recognition area, the camera recognizes the license plate and compares it with the vehicle information read by the Bluetooth device. If the comparison matches, the lane terminal generates a payment order using the fee and vehicle information and interacts with the mobile phone. The mobile phone generates a payment voucher based on the payment order. The payment voucher consists of the payment account, order information, fee, etc., and uses the mobile phone's private key to generate a non-forgeable and non-repudiable digital signature. After obtaining the payment voucher, the lane terminal submits it to the backend to complete the payment. After payment, the lane terminal retains the payment record. Immediately after payment is completed, the lane terminal raises the barrier to allow passage and uploads the exit record to the backend. The toll station exit process is as follows: Figure 4 As shown.

[0082] This embodiment ensures payment security and convenient passage without requiring users to install additional equipment. Compared to ETC toll collection technology, based on the current 100-200 million ETC installations, with each device having a 5-year lifespan and a unit price of 100-200 yuan, it can save 10-40 billion yuan in social costs over 5 years. Compared to CPC toll collection technology, it can improve the passage speed at entrances and exits, reduce traffic congestion, and simultaneously reduce the costs for highway owners to purchase, allocate, and manage CPC cards.

[0083] In summary, the high-speed non-stop toll collection method and system based on mobile phone Bluetooth described in this invention uses Bluetooth deployed in the entrance lane, gantry system, exit lane and mobile terminal for interactive communication, collects and records vehicle information, entrance information, and passing gantry information, and performs data aggregation and toll transaction in the exit lane. In scenarios without ETC devices and composite toll cards, it achieves efficient toll transaction and improves traffic efficiency.
