Description

Technical Field

[0001] This invention relates to the field of ETC identification technology, specifically to an ETC intelligent identification system. Background Technology

[0002] ETC stands for Electronic Toll Collection, which is an automatic toll collection system for highways or bridges. It uses dedicated short-range communication between an onboard electronic tag installed on the vehicle's windshield and a microwave antenna in the ETC lane at the toll station. It also uses computer networking technology to conduct back-end settlement with banks, thereby enabling vehicles to pay highway or bridge tolls without stopping when passing through toll stations.

[0003] Because of its speed and convenience, ETC toll collection is widely accepted by car owners. As a result, during peak holiday travel periods, highway ETC toll gates are often congested, or vulnerabilities in the current ETC recognition terminals are exploited to allow vehicles ahead to use their ETC, thus reducing the feasibility of the existing ETC intelligent recognition system.

[0004] Therefore, since it does not meet the existing needs, we have proposed the ETC intelligent identification system. Summary of the Invention

[0005] The purpose of this invention is to provide an ETC intelligent identification system. This system uses an emergency toll collection unit to handle non-ETC vehicles mistakenly entering ETC lanes, an IC card collection module to retrieve issued IC cards, and a mobile payment module to allow vehicle owners to pay by scanning a code. Vehicle owners do not need to return to the non-ETC lane, thus avoiding congestion at highway ETC toll gates. A vehicle inspection module checks whether the vehicle has entered the ETC automatic identification and toll collection process. If not, the ETC card reader module re-reads the vehicle's on-board electronic tag, allowing ETC vehicles to enter the process normally. A payment confirmation module confirms whether the vehicle has completed the automatic payment process. If not, an alarm module sounds an alarm, alerting staff to check whether the vehicle is using the ETC of the vehicle in front of it without permission or whether a non-ETC vehicle has mistakenly entered the ETC lane. Different actions are taken for different situations, improving the feasibility of existing ETC intelligent identification systems and solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an ETC intelligent identification system, comprising:

[0007] Onboard electronic tags are used to record the coding information of ETC vehicles;

[0008] The ETC card reader module is used to generate a vehicle approach signal when a vehicle passes by. It reads the ETC vehicle coding information recorded on the vehicle electronic tag based on RFID wireless radio frequency technology, performs intelligent timing of the ETC vehicle according to the reading time, and uploads the read coding information and timing data to the data processing center and intelligent control module respectively.

[0009] The data processing center is used to receive vehicle coding information and timing data, and to calculate and charge ETC vehicles based on the timing data;

[0010] The intelligent control module is used to receive vehicle coding information uploaded by the ETC card reader module, verify the legality of the vehicle coding information and the toll collection progress of the ETC vehicle, and send control commands to the gate to open and close the gate.

[0011] The emergency toll collection unit is used to collect tolls from non-ETC vehicles that have mistakenly entered the ETC lane.

[0012] Furthermore, the ETC card reader module also includes:

[0013] The time synchronization module is used to synchronize with the Internet time, thereby obtaining real-time time information of vehicle arrivals and departures;

[0014] The information storage module is used to save the ETC vehicle coding information data read, so as to serve as the basis for querying passage permissions later.

[0015] Furthermore, the data processing center includes:

[0016] The data receiving module is used to continuously receive vehicle coding information and vehicle timing data read by the ETC card reader module.

[0017] Furthermore, the data receiving module includes:

[0018] The time period setting module is used to set the network monitoring time period, which is obtained by the following formula:

[0019]

[0020] Where T1 represents the network monitoring time period; T p T represents the average time interval between the ETC card reader module reading vehicle coding information and vehicle timing data; T0 represents the preset time interval threshold; m represents the number of times the actual time interval between the ETC card reader module reading vehicle coding information and vehicle timing data exceeds the preset time interval threshold; T miThis represents the actual time interval when the actual time interval between the ETC card reader reading the vehicle coding information and the vehicle timing data exceeds the preset time interval threshold for the i-th occurrence; T p1 This indicates the overall average time interval when the actual time interval between the ETC card reader module reading vehicle coding information and vehicle timing data exceeds the preset time interval threshold; T p2 This represents the overall average time interval when the actual time interval between the ETC card reader module reading the vehicle coding information and the vehicle timing data does not exceed the preset time interval threshold; exp represents an exponential function with base e.

[0021] The instruction sending module is used to control the data receiving module to send a signal docking instruction to the ETC card reader when the data receiving module has not received the vehicle coding information and vehicle timing data read by the ETC card reader after the network monitoring period has expired.

[0022] The feedback instruction receiving module is used to monitor in real time whether the data receiving module receives a feedback instruction from the ETC card reader module after sending a signal docking instruction to the ETC card reader module.

[0023] The network status judgment module is used to determine whether the network communication status between the current data receiving module and the ETC card reading module is qualified based on the actual reception status of the feedback instruction.

[0024] The channel switching module is used to control the data receiving module to select an alternative communication channel to establish a communication connection with the ETC card reader when the actual reception status of the feedback command determines that the network communication status between the current data receiving module and the ETC card reader is unqualified.

[0025] Furthermore, the network status determination module includes:

[0026] The monitoring time setting module is used to set the feedback information monitoring time period, wherein the constraints for setting the feedback information monitoring time period are as follows:

[0027]

[0028] Where T2 represents the feedback information monitoring period; T1 represents the network monitoring period; T p T represents the average time interval between the ETC card reader module reading vehicle coding information and vehicle timing data; T0 represents the preset time interval threshold; m represents the number of times the actual time interval between the ETC card reader module reading vehicle coding information and vehicle timing data exceeds the preset time interval threshold; T miThis represents the actual time interval when the actual time interval between the ETC card reader reading the vehicle coding information and the vehicle timing data exceeds the preset time interval threshold for the i-th occurrence; T p1 This indicates the overall average time interval when the actual time interval between the ETC card reader module reading vehicle coding information and vehicle timing data exceeds the preset time interval threshold; T p2 This represents the overall average time interval when the actual time interval between the ETC card reader module reading the vehicle coding information and the vehicle timing data does not exceed the preset time interval threshold; exp represents an exponential function with base e.

[0029] The first judgment module is used to determine that the network communication status between the current data receiving module and the ETC card reader is unqualified if no feedback instruction is received from the ETC card reader module after the end of the feedback information monitoring period.

[0030] The evaluation parameter acquisition module is used to acquire current network communication evaluation parameters based on the reception status of the feedback instruction when it receives a feedback instruction sent by the ETC card reader module before the end of the feedback information monitoring period; wherein, the network communication evaluation parameters are acquired by the following formula:

[0031]

[0032] Where E represents the network communication evaluation parameter; E0 represents the preset baseline parameter value; Tf represents the time of receiving the feedback command during the current evaluation; T 01 and T 02 These represent the start and end times of the feedback information monitoring period, respectively; n represents the total number of times the communication channel corresponding to the current communication evaluation has passed historical communication evaluations; T fi This indicates the time when the feedback information is received when the i-th communication evaluation is successful;

[0033] The second judgment module is used to determine that the network communication status between the current data receiving module and the ETC card reader is unqualified when the network communication evaluation parameter is lower than a preset parameter threshold; and to determine that the network communication status between the current data receiving module and the ETC card reader is qualified when the network communication evaluation parameter is not lower than the preset parameter threshold.

[0034] Furthermore, the data processing center also includes:

[0035] The fee calculation module calculates the fee based on the preset toll standard and the arrival time read by the ETC card reader module, and sends the fee amount to the automatic toll collection module.

[0036] The automatic toll collection module establishes a dedicated short-range communication path between the microwave antenna and the vehicle-mounted electronic tag, and automatically deducts the toll from the sensor card installed in the ETC vehicle based on the toll amount sent by the toll calculation module.

[0037] Furthermore, the emergency charging unit includes:

[0038] IC card collection module, used to collect highway toll IC cards of non-ETC vehicles;

[0039] The mobile payment module is used to collect tolls for non-ETC vehicles based on third-party QR code payment methods, including Alipay, WeChat Pay, or UnionPay.

[0040] Furthermore, the intelligent control module also includes:

[0041] The vehicle inspection module checks whether the currently passing ETC vehicles have entered the ETC automatic identification and toll collection process normally;

[0042] The payment confirmation module is used to confirm whether the current ETC vehicle has completed the automatic payment process. If the current ETC vehicle has completed the automatic payment process, the signal is sent to the gate control module; if the current ETC vehicle has not completed the automatic payment process, the signal is sent to the alarm module.

[0043] The gate control module, based on the gate opening signal issued by the payment confirmation module, controls the gate to open to ensure the safe passage of ETC vehicles;

[0044] The alarm module, based on the alarm signal issued by the payment confirmation module, controls the alarm module to emit an alarm sound, reminding on-site staff to identify and control vehicles that have not paid but still need to pass through.

[0045] Furthermore, the vehicle inspection module checks whether the currently passing ETC vehicles have successfully entered the ETC automatic identification and toll collection process, specifically as follows:

[0046] Based on the vehicle coding information read from the ETC card reader module, the vehicle coding information of the currently passing ETC vehicle is identified, and the vehicle coding information of the current ETC vehicle is compared with the vehicle coding information of the ETC card reader module.

[0047] If the vehicle identification number of the current ETC vehicle exists in the vehicle identification number of the ETC card reader module, and the card reading time of the current ETC vehicle matches the current time, then it is determined that the current ETC vehicle has entered the ETC automatic identification and toll collection process normally.

[0048] If the vehicle identification number of the current ETC vehicle is not present in the vehicle identification number information of the ETC card reader module, and the card reading time of the current ETC vehicle does not match the current time, it is determined that the current ETC vehicle has not entered the ETC automatic identification and toll collection process normally. It is necessary to reread the on-board electronic tag of the current ETC vehicle through the ETC card reader module so that the current ETC vehicle can enter the ETC automatic identification and toll collection process normally.

[0049] Furthermore, the payment confirmation module confirms whether the current ETC vehicle has completed the automatic payment process, specifically as follows:

[0050] Based on the toll records of ETC vehicles from the data processing center, the information of current ETC vehicles is compared with the information of ETC vehicles that have been charged by the data processing center.

[0051] If the information of the current ETC vehicle already exists in the ETC vehicle information that has been charged in the data processing center, and the payment time is consistent with the current time, then it is determined that the current ETC vehicle has completed the automatic payment process.

[0052] If the information of the current ETC vehicle already exists in the ETC vehicle information that has been charged in the data processing center, but the payment time does not match the current time, it is determined that the current ETC vehicle has not completed the automatic payment process and needs to be charged through the data processing center.

[0053] If the current vehicle's information is not present in the data processing center's list of paid ETC vehicles, and the payment time is not available, then the current situation is determined to be a non-ETC vehicle mistakenly entering the ETC lane, and third-party mobile toll collection needs to be carried out on the current vehicle through the emergency toll collection unit.

[0054] Compared with the prior art, the beneficial effects of the present invention are:

[0055] 1. This invention uses an ETC card reader module to read the vehicle's onboard electronic tag, thereby obtaining the vehicle's coding information and arrival time. The system calculates the toll based on the arrival time and a preset toll standard, and settles the payment at the next highway exit. If a non-ETC vehicle mistakenly enters an ETC lane, the driver retrieves the IC card issued at the previous highway entrance using the IC card collection module in the emergency toll collection unit. The driver then uses a mobile payment module to make a third-party mobile payment by scanning a QR code, eliminating the need for the driver to reverse and enter a non-ETC lane, thus preventing congestion at highway ETC toll gates.

[0056] 2. This invention uses a vehicle inspection module to verify whether a vehicle has entered the ETC automatic identification and toll collection process normally. If the vehicle has entered the process normally, it is allowed to pass. If the vehicle has not entered the process normally, the ETC card reader module re-reads the vehicle's on-board electronic tag to enable the ETC vehicle to enter the ETC automatic identification and toll collection process normally. The payment confirmation module confirms whether the vehicle has completed the automatic payment process. If the vehicle has completed the automatic payment process, the gate control module controls the gate to open to ensure the vehicle passes safely. If the ETC vehicle has not completed the automatic payment process, the alarm module issues an alarm to remind on-site staff to check whether the vehicle is using the ETC of the vehicle in front of it without permission, or whether a non-ETC vehicle has mistakenly entered the ETC lane. This allows for different handling for different situations, thereby improving the feasibility of the existing ETC intelligent identification system. Attached Figure Description

[0057] Figure 1 This is a diagram showing the components of the ETC intelligent identification system of the present invention. Detailed Implementation

[0058] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0059] To address the frequent congestion at highway ETC toll gates during peak holiday travel periods, and to prevent situations where vulnerabilities in current ETC recognition terminals allow unauthorized use of ETC accounts by vehicles ahead, thus reducing the feasibility of existing ETC intelligent recognition systems, please refer to [link to relevant documentation]. Figure 1 This embodiment provides the following technical solution:

[0060] The ETC intelligent identification system includes:

[0061] The on-board electronic tag (OIN) is used to record the coded information of ETC vehicles. The OIN is essentially an electronic vehicle identification tag, using RFID (Radio Frequency Identification) technology to allow the ETC card reader module to read the information within it. Each OIN with RFID has a unique, unalterable ID number, providing unparalleled anti-counterfeiting capabilities. By encrypting the vehicle license plate number and vehicle registration information in the DATA area of ​​the RFID tag, and using a reader (ETC card reader module) to scan passing vehicles, it can be determined whether the current vehicle is authorized to use the OIN, thus improving the security of OIN usage. If the OIN is lost, not only can the vehicle's authorization be determined by the consistency of the vehicle registration number and registration document, but the owner can also report the loss to invalidate the tag. If a lost OIN attempts to enter or exit, it can be identified. This ensures a one-to-one correspondence between the OIN and the identified vehicle, fulfilling the true marking function of the OIN.

[0062] The ETC card reader module generates a vehicle arrival signal when a vehicle passes by. Based on RFID wireless radio frequency technology, it reads the ETC vehicle's coding information recorded on the on-board electronic tag, intelligently times the ETC vehicle based on the reading time, and uploads the read coding information and timing data to the data processing center and intelligent control module, respectively. Specifically, the on-board electronic tag records the current vehicle's coding information. In one embodiment, when the vehicle enters the ETC lane, the RFID tag in the on-board electronic tag connects to the RFID wireless radio frequency path in the ETC card reader module, thereby reading the vehicle coding information recorded in the on-board electronic tag and setting the reading time to the time the vehicle enters the highway entrance so that the vehicle can settle the toll at the exit. The read content includes, for example: license plate number Wan X11111, vehicle model Dongfeng XXXX, body color black, reading time XX year XX month XX day 9:00 am, and the above content is sent to the data processing center and intelligent control module.

[0063] The data processing center receives vehicle coding information and timing data, and calculates and charges ETC vehicles based on the timing data. Specifically, it receives and reads the content, saves the vehicle coding information as a basis for later querying vehicle access rights, records the reading time as the vehicle's departure time, and uses the ETC card reader module at the next highway exit to read the vehicle's on-board electronic tag again, using the current reading time as the end time, and calculates the fee based on the preset toll standard, thereby obtaining the fee amount.

[0064] The intelligent control module receives vehicle identification information uploaded by the ETC card reader module, verifies the legality of the vehicle identification information and the toll collection progress of the ETC vehicle, and sends control commands to the gate to open and close the gate. This effectively ensures that ETC vehicles that have paid their tolls can pass through the gate safely, and prevents ETC vehicles that have not paid their tolls and non-ETC vehicles that have mistakenly entered the ETC lane from evading or missing their tolls.

[0065] The emergency toll collection unit is used to collect tolls from non-ETC vehicles that have mistakenly entered the ETC lane. This allows drivers to avoid returning to the non-ETC lane and prevents congestion in the ETC lane.

[0066] The above works as follows: The ETC card reader module reads the vehicle's onboard electronic tag to obtain the vehicle's coding information and arrival time. Billing is then calculated based on the arrival time. At the next highway exit, the vehicle's onboard electronic tag is read again, with the current reading time serving as the end time. The billing is then settled based on the preset toll standards. The intelligent control module verifies the legality of the vehicle's coding information and the toll collection progress of ETC vehicles, thereby controlling the gate's opening and closing. An emergency toll collection unit handles non-ETC vehicles that mistakenly enter the ETC lane. The driver retrieves the IC card issued at the highway entrance through the emergency toll collection unit and makes a third-party mobile payment via QR code scanning. This eliminates the need for the driver to reverse and enter a non-ETC lane, optimizing the handling of vehicles mistakenly entering the lane and preventing escalation of conflicts between drivers and toll station staff.

[0067] The beneficial effects of the above design scheme are as follows: By verifying the legality of vehicle coding information and the toll collection progress of ETC vehicles through the intelligent control module, the normal payment of vehicle tolls is guaranteed, and the phenomenon of missed or evaded tolls is less likely to occur, thereby improving the feasibility of the existing ETC intelligent identification system; by processing non-ETC vehicles that mistakenly enter the ETC lane through the emergency toll collection unit, the driver does not need to reverse back and drive into the non-ETC lane, thereby avoiding congestion at the highway ETC toll gate.

[0068] The ETC card reader module also includes:

[0069] The time synchronization module is used to synchronize with the Internet time, thereby obtaining the real-time time information of vehicle travel. Specifically, through the time synchronization module, when the ETC card reading module reads the on-vehicle electronic tag of the current vehicle, not only the current time node is automatically recorded, but also the current year and date are recorded using the time synchronization module, so as to avoid the imperfect information caused by only recording the time node without synchronizing the date. Continuing with the above embodiment, for example: the read content is: license plate number is Wan X11111, vehicle model is Dongfeng XXXX, body color is black, and the read time is 9:00 am. Then, through the time synchronization module to synchronize with the Internet time, the read time is corrected to XX year XX month XX day 9:00 am, so as to improve the comprehensiveness of the time point and further avoid the possibility of vehicles missing or evading orders.

[0070] The information storage module is used to save the encoded information data of the ETC vehicles read, as a basis for later querying the passing authority. Specifically, by saving the encoded information data of each ETC vehicle read, a vehicle information database is generated, providing a reliable information basis for later inspection work.

[0071] The data processing center includes:

[0072] The data receiving module is used to continuously receive the vehicle encoded information and vehicle timing data read by the ETC card reading module.

[0073] Specifically, the data receiving module includes:

[0074] The time period setting module is used to set the network monitoring time period. Among them, the network monitoring time period is obtained through the following formula:

[0075]

[0076] Among them, T1 represents the set network monitoring time period; T p represents the average time interval for the ETC card reading module to read the vehicle encoded information and vehicle timing data; T0 represents the preset time interval threshold; m represents the number of times that the actual time interval for the ETC card reading module to read the vehicle encoded information and vehicle timing data exceeds the preset time interval threshold; T mi represents the actual time interval corresponding to the i-th time when the actual time interval for the ETC card reading module to read the vehicle encoded information and vehicle timing data exceeds the preset time interval threshold; T p1 represents the overall average time interval corresponding to when the actual time interval for the ETC card reading module to read the vehicle encoded information and vehicle timing data exceeds the preset time interval threshold; T p2This represents the overall average time interval when the actual time interval between the ETC card reader module reading the vehicle coding information and the vehicle timing data does not exceed the preset time interval threshold; exp represents an exponential function with base e.

[0077] The instruction sending module is used to control the data receiving module to send a signal docking instruction to the ETC card reader when the data receiving module has not received the vehicle coding information and vehicle timing data read by the ETC card reader after the network monitoring period has expired.

[0078] The feedback instruction receiving module is used to monitor in real time whether the data receiving module receives a feedback instruction from the ETC card reader module after sending a signal docking instruction to the ETC card reader module.

[0079] The network status judgment module is used to determine whether the network communication status between the current data receiving module and the ETC card reading module is qualified based on the actual reception status of the feedback instruction.

[0080] The channel switching module is used to control the data receiving module to select an alternative communication channel to establish a communication connection with the ETC card reader when the actual reception status of the feedback command determines that the network communication status between the current data receiving module and the ETC card reader is unqualified.

[0081] The technical effect of the above solution is as follows: By setting a time period module, a network monitoring time period can be defined, that is, a time window is specified to monitor the data reception of the ETC card reader module. This allows for real-time monitoring of network communication status, thereby enabling timely detection of problems.

[0082] When the data receiving module does not receive vehicle identification information and vehicle timing data from the ETC card reader module within the network monitoring period, the command sending module will send a signal docking command to the ETC card reader module. This proactively controls the communication between the data receiving module and the ETC card reader module to ensure the stability of data transmission.

[0083] The feedback command receiving module monitors in real time whether the ETC card reader module has returned feedback commands, and determines whether the current network communication status is acceptable based on the received feedback commands. If the network communication status is found to be unacceptable, the channel switching module will switch to another communication channel to re-establish a communication connection with the ETC card reader module, thereby improving the stability and reliability of communication.

[0084] In summary, this technical solution effectively optimizes communication between the data receiving module and the ETC card reader module by real-time monitoring of network communication status, proactively controlling the transmission of communication commands, and automatically switching communication channels when communication status is unsatisfactory. This improves the success rate and stability of data transmission. This helps ensure the accuracy and timeliness of data collection, enhancing the overall system performance and reliability.

[0085] Specifically, the network status determination module includes:

[0086] The monitoring time setting module is used to set the feedback information monitoring time period, wherein the constraints for setting the feedback information monitoring time period are as follows:

[0087]

[0088] Where T2 represents the feedback information monitoring period; T1 represents the network monitoring period; T p T represents the average time interval between the ETC card reader module reading vehicle coding information and vehicle timing data; T0 represents the preset time interval threshold; m represents the number of times the actual time interval between the ETC card reader module reading vehicle coding information and vehicle timing data exceeds the preset time interval threshold; T mi This represents the actual time interval when the actual time interval between the ETC card reader reading the vehicle coding information and the vehicle timing data exceeds the preset time interval threshold for the i-th occurrence; T p1 This indicates the overall average time interval when the actual time interval between the ETC card reader module reading vehicle coding information and vehicle timing data exceeds the preset time interval threshold; T p2 This represents the overall average time interval when the actual time interval between the ETC card reader module reading the vehicle coding information and the vehicle timing data does not exceed the preset time interval threshold; exp represents an exponential function with base e.

[0089] The first judgment module is used to determine that the network communication status between the current data receiving module and the ETC card reader is unqualified if no feedback instruction is received from the ETC card reader module after the end of the feedback information monitoring period.

[0090] The evaluation parameter acquisition module is used to acquire current network communication evaluation parameters based on the reception status of the feedback instruction when it receives a feedback instruction sent by the ETC card reader module before the end of the feedback information monitoring period; wherein, the network communication evaluation parameters are acquired by the following formula:

[0091]

[0092] Where E represents the network communication evaluation parameter; E0 represents the preset baseline parameter value; Tf represents the time of receiving the feedback command during the current evaluation; T 01 and T 02 These represent the start and end times of the feedback information monitoring period, respectively; n represents the total number of times the communication channel corresponding to the current communication evaluation has passed historical communication evaluations; T fi This indicates the time when the feedback information is received when the i-th communication evaluation is successful;

[0093] The second judgment module is used to determine that the network communication status between the current data receiving module and the ETC card reader is unqualified when the network communication evaluation parameter is lower than a preset parameter threshold; and to determine that the network communication status between the current data receiving module and the ETC card reader is qualified when the network communication evaluation parameter is not lower than the preset parameter threshold.

[0094] The technical effect of the above solution is as follows: By setting a monitoring time module, a feedback information monitoring period can be defined, that is, a time window is specified to monitor the reception of feedback information from the ETC card reader module. This allows for the evaluation of the communication status within a predetermined time range, avoiding communication problems caused by prolonged waiting without feedback.

[0095] The first judgment module determines that if no feedback instruction is received from the ETC card reader module after the feedback information monitoring period ends, the network communication status between the current data receiving module and the ETC card reader module is unqualified. This allows for timely detection of communication faults or problems, enabling appropriate measures to be taken.

[0096] The evaluation parameter acquisition module obtains the current network communication evaluation parameters based on the received feedback instructions. By calculating these evaluation parameters, a more comprehensive understanding of the historical performance of the communication channel can be achieved, thereby more accurately assessing the current communication status.

[0097] The second judgment module compares the network communication evaluation parameters with preset parameter thresholds to determine whether the network communication status between the current data receiving module and the ETC card reader module is acceptable. When the evaluation parameters are lower than the preset threshold, the communication status is deemed unacceptable, and corresponding processing measures need to be taken, such as switching the communication channel or performing other network optimizations.

[0098] In summary, this technical solution, by monitoring and evaluating network communication status in real time, can promptly identify communication problems and take corresponding measures, thereby improving the reliability and stability of data transmission and ensuring accurate data delivery and timely retrieval. This helps optimize the performance and availability of the data acquisition system, and improves the success rate and efficiency of data transmission.

[0099] The fee calculation module calculates the fee based on a preset toll standard and the arrival time read by the ETC card reader module, and sends the fee amount to the automatic toll collection module. Specifically, it records the departure time of the vehicle at the previous highway entrance as the departure time and the end time at the next highway exit as the end time, and calculates the fee amount by combining this with the preset toll standard. Following the above example, for instance, if the reading time at the previous highway entrance is 9:00 am on [date] and 5:00 pm on [date], it is estimated that the vehicle has been traveling on the highway for 8 hours. If the preset toll standard is 3 RMB / hour, the calculated fee for the current vehicle is 24 RMB, and this 24 RMB is sent to the automatic toll collection module for payment.

[0100] The automatic toll collection module establishes a dedicated short-range communication path between a microwave antenna and the vehicle-mounted electronic tag. Combined with the toll amount sent by the toll calculation module, it automatically deducts the toll from the sensor card installed in the ETC vehicle. Specifically, by installing a sensor card (a UnionPay card with a chip connection) in the current ETC vehicle, the automatic toll collection module uses the received toll amount as a benchmark and connects to the sensor card to automatically deduct the toll. Following the above embodiment, for example, if the current toll amount for the vehicle is 24 RMB, the automatic toll collection module will automatically deduct 24 RMB from the sensor card installed in the ETC vehicle. The issuing unit of the sensor card will also send a deduction SMS to the vehicle owner's mobile phone as a reminder. This avoids the need for the vehicle owner to lean out significantly to swipe the card, improving the convenience of ETC passage.

[0101] Emergency charging units include:

[0102] The IC card collection module is used to collect the highway toll IC cards of non-ETC vehicles. Specifically, the IC card collection module is an IC card storage box that can be installed on the left side of the ETC lane. This allows drivers who mistakenly enter the ETC lane to deposit the IC card issued at the previous highway entrance into the IC card storage box, avoiding the need for drivers to return to the non-ETC lane for processing, thus providing convenience for drivers.

[0103] The mobile payment module uses third-party QR code payment methods to collect tolls from non-ETC vehicles. These methods include Alipay, WeChat Pay, or UnionPay. Specifically, the mobile payment module is a QR code payment sign that can be installed on the left side of the ETC lane, alongside the IC card collection box. When a non-ETC vehicle mistakenly enters the ETC lane, the driver can pay the toll by scanning the code with their mobile phone, thus speeding up the processing of such situations and preventing non-ETC vehicles from causing congestion in the ETC lane.

[0104] The intelligent control module also includes:

[0105] The vehicle inspection module verifies whether currently passing ETC vehicles have successfully entered the ETC automatic identification and toll collection process; specifically:

[0106] Based on the vehicle coding information read from the ETC card reader module, the vehicle coding information of the currently passing ETC vehicle is identified, and the vehicle coding information of the current ETC vehicle is compared with the vehicle coding information of the ETC card reader module.

[0107] In one embodiment, if the vehicle code information of the current ETC vehicle exists in the vehicle code information of the ETC card reader module, and the card reading time of the current ETC vehicle matches the current time, then it is determined that the current ETC vehicle has entered the ETC automatic identification and toll collection process normally.

[0108] If the vehicle identification number of the current ETC vehicle is not present in the vehicle identification number information of the ETC card reader module, and the card reading time of the current ETC vehicle does not match the current time, it is determined that the current ETC vehicle has not entered the ETC automatic identification and toll collection process normally. It is necessary to reread the on-board electronic tag of the current ETC vehicle through the ETC card reader module so that the current ETC vehicle can enter the ETC automatic identification and toll collection process normally.

[0109] The payment confirmation module is used to confirm whether the current ETC vehicle has completed the automatic payment process. If the current ETC vehicle has completed the automatic payment process, the signal is sent to the gate control module; if the current ETC vehicle has not completed the automatic payment process, the signal is sent to the alarm module. Specifically:

[0110] Based on the toll records of ETC vehicles from the data processing center, the information of current ETC vehicles is compared with the information of ETC vehicles that have been charged by the data processing center.

[0111] In one embodiment, if the information of the current ETC vehicle already exists in the ETC vehicle information that has been charged in the data processing center, and the payment time is consistent with the current time, then it is determined that the current ETC vehicle has completed the automatic payment process.

[0112] If the information of the current ETC vehicle already exists in the ETC vehicle information that has been charged in the data processing center, but the payment time does not match the current time, it is determined that the current ETC vehicle has not completed the automatic payment process and needs to be charged through the data processing center.

[0113] If the current vehicle's information is not present in the data processing center's list of paid ETC vehicles, and the payment time is not available, then the current situation is determined to be a non-ETC vehicle mistakenly entering the ETC lane, and third-party mobile toll collection needs to be carried out on the current vehicle through the emergency toll collection unit.

[0114] The gate control module, based on the gate opening signal issued by the payment confirmation module, controls the gate to open to ensure the safe passage of ETC vehicles;

[0115] The alarm module, based on the alarm signal issued by the payment confirmation module, controls the alarm module to emit an alarm sound, reminding on-site staff to identify and control vehicles that have not paid but still need to pass through.

[0116] The working principle of the above is as follows: The vehicle inspection module checks whether the current vehicle has entered the ETC automatic identification and toll collection process normally. If the current vehicle has entered the process normally, it is allowed to pass. If the current vehicle has not entered the process normally, the ETC card reader module rereads the vehicle's on-board electronic tag, allowing the current ETC vehicle to enter the ETC automatic identification and toll collection process normally. The payment confirmation module confirms whether the current vehicle has completed the automatic payment process. If the current vehicle has completed the automatic payment process, the gate control module controls the gate to open, ensuring the vehicle passes safely. If the current ETC vehicle has not completed the automatic payment process, the alarm module issues an alarm, reminding on-site staff to check whether the current vehicle is using the ETC of the vehicle in front of it, or whether a non-ETC vehicle has mistakenly entered the ETC lane. Different actions are taken for different situations, thereby improving the feasibility of the existing ETC intelligent identification system.

[0117] The beneficial effects of the above design scheme are: by checking whether the current vehicle has entered the ETC automatic identification and toll collection process normally through the vehicle inspection module, it ensures that the current vehicle has completed payment before being released, thereby preventing vehicles from missing or evading payment or using the ETC of the vehicle in front, protecting the rights and interests of each car owner, and further improving the feasibility of the existing ETC intelligent identification system.

[0118] Working principle: The system reads the vehicle's onboard electronic tag via the ETC card reader module, calculates the toll based on the arrival time and toll standard, and settles the payment at the exit. If a non-ETC vehicle mistakenly enters the ETC lane, the driver retrieves the issued IC card via the IC card collection module and uses the mobile payment module to scan and settle the payment, eliminating the need for the driver to return to the non-ETC lane and preventing congestion at the highway ETC toll gate. The vehicle inspection module checks whether the vehicle has entered the ETC automatic recognition and toll collection process normally. If it has not entered the process normally, the ETC card reader module rereads the vehicle's onboard electronic tag to ensure normal entry. The payment confirmation module confirms whether the vehicle has completed the automatic payment process. If the automatic payment process has not been completed, the alarm module sounds an alarm, alerting on-site staff to check whether the vehicle is using the ETC of the vehicle in front of it without permission or whether a non-ETC vehicle has mistakenly entered the ETC lane. Different actions are taken for different situations, improving the feasibility of the existing ETC intelligent recognition system.
