Description

Technical Field

[0001] The invention belongs to the technical field of highway toll collection, and in particular relates to a CPC card information reading and transaction data multiple verification system. Background Art

[0002] As traffic volume continues to rise, efficient operation of toll booths is becoming increasingly critical; however, there are many problems with the current CPC card information reading process. When a vehicle passes through a toll station at high speed, the information in the CPC card may be incomplete or erroneous due to factors such as high speed and communication interference. Real-time monitoring is required to ensure the accuracy of information reading. In terms of fee calculation, the traditional fee calculation method is relatively simple and lacks comprehensive consideration of different situations, such as special policy considerations for vehicles registered in the province and reference to historical vehicle traffic data, which can easily lead to inaccurate billing; In terms of fee verification, the existing verification mechanism is not perfect and lacks security. For this reason, we propose a CPC card information reading and transaction data multiple verification system. Summary of the invention

[0003] The object of the present invention is to provide a CPC card information reading and transaction data multiple verification system to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned object, the present invention provides the following technical solutions: a CPC card information reading and transaction data multiple verification system, comprising a CPC card information reading module, an operation and maintenance update module, a database, a billing module, a verification module and a payment processing module; CPC card information reading module: extracts the driving information of the vehicle in the CPC card, and performs reading detection and verification on the driving information of the vehicle. If the detection and verification is successful, it is determined as qualified reading, otherwise it is unqualified reading. The driving information corresponding to the unqualified reading has unqualified key items. The driving information corresponding to the qualified reading is sent to the calculation module, and the driving information of the vehicle corresponding to the unqualified reading is manually checked. If the manual verification result shows that there is no error in the driving information stored in the CPC card, the driving information of the vehicle is recorded as misread information and sent to the operation and maintenance update module; Operation and maintenance update module: A fixed number of vehicles are selected from the past vehicle flow at equal intervals and integrated into a detection group. The number of key items in the misread information in the detection group that fail to meet the standards is counted, and a comprehensive analysis is performed to obtain an operation and maintenance evaluation value. When the operation and maintenance evaluation value is greater than the corresponding threshold, a read operation and maintenance instruction is generated and sent to the highway network operation and maintenance end, so that it can dispatch staff to troubleshoot and repair system reading problems. Database: Use the license plate number as an index to store the vehicle's entry and exit time, entry and exit number, CPC card number when entering the toll station, toll fees, number of times, and toll evasion record information; Billing module: calculates the toll of the vehicle and detects whether it is a vehicle registered in the province. For vehicles registered in the province, the maximum amount limit threshold is matched according to the vehicle type to determine whether the toll exceeds the limit. If so, the toll is re-billed; Verification module: performs rate legitimacy verification and online billing verification on tolls; if both verifications pass, the tolls are sent to the payment processing module; Payment processing module: payment of vehicle communication fees and CPC return and verification.

[0005] Preferably, the specific process of the CPC card information reading module is: When the vehicle drives to the ramp free-flow trading gantry in front of the toll station, it communicates with the CPC card through the antenna of the ramp free-flow trading gantry. At the same time, the image of the vehicle is captured by the high-definition camera equipped at the ramp free-flow trading gantry, and the vehicle passing through the ramp free-flow trading gantry is marked as a target vehicle. The target vehicle driving information stored in the CPC card is read. The driving information includes: vehicle type, license plate number, entrance toll station number, passing section mark, marked section mileage, CPC card identification code; the vehicle type, license plate number, entrance toll station number, passing section mark, and marked section mileage in the driving information are marked as key items, and each key item in the target vehicle driving information is subjected to reading qualification inspection and verification.

[0006] Preferably, the specific process of performing read eligibility test and verification on each key item in the target vehicle driving information is as follows: For each target vehicle, a high-definition camera is installed at the ramp free-flow transaction gantry to capture the image of the target vehicle, identify the image of the target vehicle, and obtain the body length, height, number of axles, and number of wheels of the target vehicle; each vehicle type is preset with a corresponding vehicle length, height, number of axles, and number of wheels interval, obtain the vehicle type read in the CPC card of the target vehicle, and detect whether the body length, height, number of axles, and number of wheels of the target vehicle are within the vehicle length, height, number of axles, and number of wheels intervals of the read vehicle type. If all are in compliance, it is recorded as a qualified vehicle type reading; if not, it is recorded as an unqualified vehicle type reading; The license plate number of the target vehicle identified by the image is compared with the license plate number read from the CPC card of the target vehicle. If they are consistent, it is recorded as the license plate number reading is qualified, and if they are inconsistent, it is recorded as the license plate number reading is unqualified; According to the license plate number of the target vehicle, the number corresponding to the most recent entrance toll station is retrieved from the database to obtain the entrance toll station number of the target vehicle. The entrance toll station number of the target vehicle is compared with the toll station number read from the CPC card of the target vehicle. If they are consistent, it is recorded as the entrance toll station number reading is qualified. If they are inconsistent, it is recorded as the entrance toll station number reading is unqualified; The target vehicle passes through the entrance toll station and the exit toll station, obtains the road section identification that the target vehicle needs to pass through during the driving process in the order of time, which is recorded as the detection order, obtains the road section identification read from the CPC card in the order of time, which is recorded as the reading order, and compares the detection order with the reading order. If they are consistent, it is recorded as the passing road section identification reading is qualified, and if they are inconsistent, it is recorded as the passing road section identification reading is unqualified; According to the entrance and exit toll stations of the target vehicle, the actual mileage of the target vehicle on each marked section is calculated and recorded as the detection mileage. At the same time, the read mileage of the corresponding marked section in the CPC card is obtained, and the absolute value of the difference between the detection mileage and the read mileage of each marked section is recorded as the deviation mileage. A deviation mileage threshold is preset. If the deviation mileage is less than the threshold, the section record is determined to be qualified, otherwise it is unqualified. When all marked sections are determined to be qualified, the mileage record of the marked section is determined to be qualified; as long as there is an unqualified record of the marked section, the mileage record of the marked section is determined to be unqualified; If the key items in the vehicle's driving information fail to read properly, the target vehicle will be recorded as an abnormal vehicle; the image recognition technology will be used to identify the license plate number of the abnormal vehicle, and the license plate number of the abnormal vehicle will be sent to the monitoring center of the exit toll station. After the monitoring center receives the license plate number information, the staff will guide the abnormal vehicle to a special inspection area for offline manual inspection and charging; if the manual inspection result shows that there is no error in the driving information stored in the CPC card of the abnormal vehicle, the driving information of the abnormal vehicle will be recorded as misread information and sent to the operation and maintenance update module.

[0007] Preferably, the specific working steps of the operation and maintenance update module are: From the past target vehicle flow, a fixed number of vehicles are selected at equal intervals and integrated into a vehicle group. The driving information of each target vehicle in the vehicle group is summarized to form a detection group. The driving information corresponding to a single target vehicle in the vehicle group is recorded as a detection sample. For each test group, a bar chart is established for key items. In the bar chart, the horizontal axis is used to list the key items, and the vertical axis counts the number of key items that fail to read. When the test sample in the test group has misread information, the key item that fails to read in the misread information is mapped to the corresponding key item position in the bar chart, and 1 is added to the number on the vertical axis; The vehicle type, license plate number, entrance toll station number, section mark, and number of unqualified mileage read in the bar chart are marked as CX, CA, CH, CT, and CS respectively; the operation and maintenance evaluation value YP is obtained by using the formula: YP=CX×a1+CA×a2×CH×a3+CT×a4+CS×a5, where a1, a2, a3, a4, and a5 are preset weight coefficients. Whenever a test sample in the test group shows misreading information, and the key items showing unqualified reading in the misreading information are substituted into the key item bar chart, the operation and maintenance evaluation value is calculated once, and the operation and maintenance evaluation threshold is preset. When the operation and maintenance evaluation value is greater than the preset operation and maintenance evaluation threshold, a read operation and maintenance instruction is generated and sent to the highway network operation and maintenance end. After the highway network operation and maintenance end receives the system read operation and maintenance instruction, it dispatches staff to troubleshoot and repair the system reading problem.

[0008] Preferably, the charging module calculates the toll according to the vehicle driving information, and the specific calculation method is as follows: When the driving information of the target vehicle is received, the license plate number, vehicle type, section identification passed through and the corresponding mileage of each identified section in the driving information are read; different vehicle types are preset with corresponding calculation rates at different section identifications; the vehicle type of the target vehicle and the section identification passed through during its driving process are matched with the preset calculation rates set for different vehicle types at different section identifications one by one, and the rate corresponding to the target vehicle when driving on each section identification is output; the mileage of each identified section passed by the target vehicle is multiplied by the rate of the corresponding section identification, and these products are summed up to obtain the toll of the target vehicle, which is recorded as the target toll.

[0009] Preferably, the charging module detects whether the vehicle is registered in the province. For vehicles registered in the province, the maximum amount limit threshold is matched according to the vehicle type to determine whether the toll exceeds the limit. If the toll exceeds the limit, the specific process of re-charging is as follows: The first two characters of the target vehicle's license plate number are compared with the first two characters of the license plate number of the province. If they are inconsistent, the target vehicle's toll is sent to the fee verification module; If they are consistent, the target vehicle is judged to be a vehicle registered in this province; it is preset that different types of vehicles registered in this province are all set with corresponding maximum amount limit thresholds, the vehicle type of the target vehicle is matched with the maximum amount limit threshold set for different types of vehicles registered in this province, the corresponding maximum amount limit threshold is output, and the target vehicle's sight-to-sight fee is compared with the corresponding maximum amount limit threshold. If the target vehicle's sight-to-sight fee is less than or equal to the corresponding maximum amount limit threshold, the target vehicle's sight-to-sight fee is sent to the fee verification module; if the target vehicle's sight-to-sight fee is greater than the corresponding maximum amount limit threshold, the billing discount process is started; The specific implementation process of the re-billing process is as follows: For each target vehicle, the historical tolls, number of passes and toll evasion records of the target vehicle are extracted from the database according to the license plate number of the target vehicle, and the total toll amount TA, the total number of passes TC and the total number of toll evasion records TF are calculated. Different types of vehicles registered in the province are preset to have corresponding rate coefficients. The vehicle type of the target vehicle is matched with the rate coefficients set for different types of vehicles registered in the province, and the rate coefficient FX corresponding to the target vehicle is output; The toll amount TA, the total number of toll passes TC, the total number of toll evasion records TF and the rate coefficient FX of the target vehicle are normalized and then input into the preset formula: YHF=(TA×b1+TC×b2-TF×b3)×FX to obtain the rate discount coefficient YHF, wherein b1, b2 and b3 are preset weight coefficients, and different types of vehicles are preset with corresponding maximum rate discount coefficients. The vehicle type of the target vehicle is matched with the preset maximum rate discount coefficient corresponding to different types of vehicles, and the corresponding maximum discount coefficient is output. The rate discount coefficient of the target vehicle is compared with the corresponding maximum rate discount coefficient. If the rate discount coefficient of the target vehicle is greater than the corresponding maximum rate discount coefficient, the maximum discount coefficient corresponding to the target vehicle is used as the discount coefficient of the target vehicle. The discount amount is obtained by multiplying the target vehicle's initially calculated toll by the target vehicle's discount coefficient, and the target vehicle's initially calculated toll is subtracted from the discount amount to obtain the updated toll of the target vehicle, and the updated toll is sent to the fee verification module.

[0010] Preferably, the working process of the verification module is: Rate legitimacy verification: Different vehicle types are preset with minimum rates at different road section signs. According to the target vehicle's driving path, the mileage of each marked road section passed by the target vehicle is multiplied by the minimum rate of the road section sign corresponding to its corresponding vehicle type, and these products are summed up to obtain the minimum toll for the target vehicle, which is recorded as the minimum toll for each section. The target vehicle's toll is compared with the minimum toll for each section. If the target vehicle's toll is less than the minimum toll for each section, the vehicle is marked as a vehicle with abnormal toll billing, and the license plate number of the vehicle with abnormal toll billing is sent to the monitoring center of the exit toll station. After the monitoring center receives the license plate number information of the vehicle with abnormal toll billing, the staff guides the vehicle with abnormal toll billing to a special inspection area for offline manual toll inspection. Online billing verification: If the toll of the target vehicle is greater than or equal to the minimum toll, the verification module will establish a high-speed data exchange channel with the online billing system of the highway network toll collection center, and send the vehicle type, license plate number, entrance toll station number, section identification, mileage of the identified section, and exit toll station number of the target vehicle to the online billing system; after receiving the toll amount feedback from the online billing system, the toll is subtracted from the toll of the target vehicle and the absolute value is taken to obtain the toll deviation value, and the toll deviation value threshold is preset. If the toll deviation value is less than or equal to the corresponding threshold, the toll is sent to the payment processing module; If the fee deviation value is greater than the corresponding threshold, network troubleshooting information is generated and sent to the highway network operation and maintenance end. The highway network operation and maintenance end dispatches staff to conduct self-inspection and self-correction to check whether the local system data update is lagging behind and whether there is data loss or error during network transmission.

[0011] Preferably, the specific working process of the payment processing module is: Payment QR codes are placed in conspicuous positions on both sides of the toll lane, and a display is installed adjacent to them. When a vehicle slowly enters the toll lane, the camera above the display quickly captures the license plate number of the target vehicle, and then accurately matches and displays the corresponding toll for the vehicle based on the license plate number; the driver scans the payment QR code as instructed to complete the payment operation, and the moment the payment is successful, the voice prompt system in the control toll booth reminds the driver to return the CPC card; the driver inserts the CPC card into the card reader, and compares the CPC card number of the inserted card with the pre-recorded CPC card number of the vehicle with the corresponding license plate number to see if they match; if the two match, the control lane railing is automatically raised, allowing the vehicle to quickly leave the toll lane; if the CPC card number verified by the card reader does not match the CPC card number recorded for the vehicle with the corresponding license plate number, the display screen in the control toll booth pops up a prompt "CPC card information is incorrect, please contact staff for processing", and at the same time sends an offline verification notice to the staff.

[0012] Compared with the prior art, the present invention has the following beneficial effects: (1) This CPC card information reading and transaction data multiple verification system greatly improves the accuracy of information reading by performing read qualification detection and verification on key items in vehicle driving information, effectively avoiding billing errors caused by information errors; once it is found that the vehicle driving information reading is unqualified, it is quickly marked as an abnormal vehicle, and the vehicle is guided to the verification area for offline manual verification and charging, ensuring that the problem vehicle is handled in a timely manner and does not affect the normal charging order; the operation and maintenance update module selects vehicles at equal intervals to form a detection group, performs statistical analysis on the number of unqualified key items in the misread information, generates an operation and maintenance evaluation value, and through a preset threshold, when the operation and maintenance evaluation value exceeds the threshold, promptly notifies the operation and maintenance personnel to troubleshoot and repair the system reading problem, thereby realizing the system's real-time monitoring of its own information reading performance, ensuring the stability and reliability of the information reading system, and continuously ensuring the high quality of information reading.

[0013] (2) This CPC card information reading and transaction data multiple verification system accurately calculates tolls based on various key data in the vehicle driving information, such as license plate number, vehicle type, road section identification and mileage, combined with the preset calculation rates of different vehicle types at different road section identifications. This billing method fully considers the actual driving conditions of the vehicle, so that the fee calculation fits the actual cost and resource consumption, and ensures the rationality and fairness of the charges; for vehicles registered in the province, the maximum amount limit threshold is matched according to the vehicle type, effectively preventing the overcharging of vehicles registered in the province due to special circumstances; and with the help of the vehicle's historical tolls, number of passes and evasion records stored in the database, combined with the preset rate coefficient for vehicles registered in the province, the re-billing process is initiated for vehicles registered in the province that may be overcharged, and the past behavior of the vehicle is comprehensively considered to achieve personalized and rational charges, improve the owner's payment satisfaction, and reduce toll disputes.

[0014] (3) This CPC card information reading and transaction data multiple verification system calculates the minimum toll according to the lowest toll rate of different vehicle types and road section signs through rate legitimacy verification, and uses this as a benchmark to screen out vehicles with abnormally low tolls to prevent unreasonable situations such as toll evasion. Once it is found that the vehicle's toll is lower than the minimum toll, the vehicle is immediately marked as a vehicle with abnormal toll billing, and the monitoring center is notified to arrange manual verification, which sets a clear bottom line for charging. For vehicles whose toll passes the legitimacy verification, the online billing verification establishes a high-speed data interaction channel with the online billing system of the networked toll center, shares the target vehicle's full range of information in real time, including key data such as vehicle type and driving route, and quickly compares the feedback of toll receivable amount with the locally calculated toll. This process realizes cross-system data collaborative verification, fully utilizes the massive data and powerful computing power of the networked center, improves the accuracy of local toll collection, and reduces billing deviations caused by regional and system differences.

[0016] 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.

[0017] Embodiment 1

[0018] See also Figure 1 - Figure 2 , the present invention provides a CPC card information reading and transaction data multiple verification system, including a CPC card information reading module, an operation and maintenance update module, a database, a billing module, a verification module and a payment processing module; The CPC card information reading module is used to collect the vehicle's driving information and read and check the vehicle's driving information. If the check is successful, it is determined as qualified reading, otherwise it is determined as unqualified reading. The driving information corresponding to the qualified reading is sent to the calculation module, and the unqualified one is marked as abnormal and guided for manual verification. The specific process is as follows: When the vehicle drives to the ramp free-flow transaction gantry in front of the toll station, the ramp free-flow transaction gantry antenna is used to communicate with the CPC card, and the high-definition camera equipped at the ramp free-flow transaction gantry is used to capture the image of the vehicle, and the vehicle passing through the ramp free-flow transaction gantry is marked as a target vehicle. The target vehicle driving information stored in the CPC card is read. The driving information includes: vehicle type, license plate number, entrance toll station number, passing section mark, marked section mileage, CPC card identification code; the vehicle type, license plate number, entrance toll station number, passing section mark, marked section mileage in the driving information are marked as key items, and each key item in the target vehicle driving information is subjected to a read qualification test; The process of reading the key items in the target vehicle driving information for qualification testing is as follows: For each target vehicle, the image of the target vehicle is photographed by a high-definition camera equipped at the ramp free-flow transaction gantry, the image of the target vehicle is identified, and the body length, height, number of axles, and number of wheels of the target vehicle are obtained; each vehicle type is preset with a corresponding vehicle length, height, number of axles, and number of wheels interval, the vehicle type read in the CPC card of the target vehicle is obtained and matched with the vehicle length, height, number of axles, and number of wheels intervals corresponding to each vehicle type, the body length, height, number of axles, and number of wheels of the target vehicle type are output, and the body length, height, number of axles, and number of wheels of the target vehicle type are detected to see whether they are within the vehicle length, height, number of axles, and number of wheels intervals of the read vehicle type. If all are in compliance, it is recorded as qualified vehicle type reading; if not, it is recorded as unqualified vehicle type reading; The license plate number of the target vehicle identified by the image is compared with the license plate number read from the CPC card of the target vehicle. If they are consistent, it is recorded as the license plate number reading is qualified, and if they are inconsistent, it is recorded as the license plate number reading is unqualified; According to the license plate number of the target vehicle, the number corresponding to the most recent entrance toll station is retrieved from the database to obtain the entrance toll station number of the target vehicle. The entrance toll station number of the target vehicle is compared with the toll station number read from the CPC card of the target vehicle. If they are consistent, it is recorded as the entrance toll station number reading is qualified. If they are inconsistent, it is recorded as the entrance toll station number reading is unqualified; The target vehicle passes through the entrance toll station and the exit toll station, obtains the road section identification that the target vehicle needs to pass through during the driving process in the order of time, which is recorded as the detection order, obtains the road section identification read from the CPC card in the order of time, which is recorded as the reading order, and compares the detection order with the reading order. If they are consistent, it is recorded as the passing road section identification reading is qualified, and if they are inconsistent, it is recorded as the passing road section identification reading is unqualified; According to the entrance and exit toll stations of the target vehicle, the actual mileage of the target vehicle on each marked section is calculated and recorded as the detection mileage. At the same time, the read mileage of the corresponding marked section in the CPC card is obtained, and the absolute value of the difference between the detection mileage and the read mileage of each marked section is recorded as the deviation mileage. A deviation mileage threshold is preset. If the deviation mileage is less than the threshold, the section record is determined to be qualified, otherwise it is unqualified. When all marked sections are determined to be qualified, the mileage record of the marked section is determined to be qualified; as long as there is an unqualified record of the marked section, the mileage record of the marked section is determined to be unqualified; If the key items in the vehicle driving information are not read properly, the target vehicle will be recorded as an abnormal vehicle; the license plate number of the abnormal vehicle will be identified by image recognition technology, and the license plate number of the abnormal vehicle will be sent to the monitoring center of the exit toll station. After the monitoring center receives the license plate number information, the staff will guide the abnormal vehicle to stop at a special verification area for offline manual verification and charging; if the manual verification result shows that there is no error in the driving information stored in the CPC card of the abnormal vehicle, the driving information of the abnormal vehicle will be recorded as misread information and sent to the operation and maintenance update module; If all key items in the target vehicle's driving information are read as qualified, the target vehicle's driving information is sent to the calculation module; It should be noted that intervention is made in advance before the vehicle arrives at the toll station to collect detailed driving information such as vehicle type, license plate number, entrance toll station number, etc., to provide key and accurate data support for the subsequent accurate calculation of tolls, avoid charging deviations due to missing or incorrect information, and ensure the rationality of charging. By verifying key items and comprehensively checking information errors, the risk of erroneous data flowing into subsequent billing processes is greatly reduced, effectively reducing charging disputes. Once it is found that the vehicle's driving information reading is unqualified, it will be quickly marked as an abnormal vehicle, and the license plate number will be transmitted to the monitoring center with the help of image recognition technology, and the vehicle will be guided to the verification area for offline manual verification and charging, which ensures that problem vehicles are dealt with in a timely manner and do not affect the normal charging order.

[0019] The operation and maintenance update module selects vehicles from the past target vehicle flow at equal intervals and integrates them into detection groups. It counts the number of key items that fail in the misread information in the detection group, and performs comprehensive analysis to obtain the operation and maintenance evaluation value. It determines whether there is a problem with the system information reading based on the operation and maintenance evaluation value. The specific process is as follows: From the past target vehicle flow, a fixed number of vehicles are selected at equal intervals and integrated into a vehicle group, where the fixed number is set by the system staff according to the actual situation. The driving information of each target vehicle in the vehicle group is summarized to form a detection group, and the driving information corresponding to a single target vehicle in the vehicle group is recorded as a detection sample; for example: from the target vehicles leading to the road, every 100 target vehicles are a vehicle group, and the driving information corresponding to each target vehicle in the group is a detection sample; For each detection group, a bar chart is created for key items, such as Figure 2 In this bar chart, the horizontal axis is used to list the key items, and the vertical axis counts the number of key items that fail to read. When a test sample in the test group has misread information, the key item that fails to read in the misread information is mapped to the corresponding key item position in the bar chart, and 1 is added to the number on the vertical axis; The vehicle type, license plate number, entrance toll station number, section mark, and number of unqualified readings of the marked section in the bar chart are marked as CX, CA, CH, CT, and CS respectively; the operation and maintenance evaluation value YP is obtained by using the formula: YP=CX×a1+CA×a2×CH×a3+CT×a4+CS×a5, where a1, a2, a3, a4, and a5 are preset weight coefficients. Whenever a test sample in the test group is misread, and the key item showing unqualified reading in the misread information is substituted into the key item bar chart, the operation and maintenance evaluation value is calculated once, and the operation and maintenance evaluation threshold is preset. When the operation and maintenance evaluation value is greater than the preset operation and maintenance evaluation threshold, a read operation and maintenance instruction is generated and sent to the highway network operation and maintenance end. After the highway network operation and maintenance end receives the system read operation and maintenance instruction, it dispatches staff to troubleshoot and repair the system reading problem; the staff can check the system modules corresponding to the key items with a large number of unqualified readings and a greater impact on the accuracy of the toll collection based on the key items of the problem reflected by the operation and maintenance evaluation value; It should be noted that, on the one hand, data aggregation makes the analysis of key items more targeted; by establishing a bar chart, the horizontal axis lists key items such as vehicle type and license plate number, and the vertical axis counts the number of unqualified readings. Once there is misread information in the detection group, the key items of the problem can be quickly mapped to the bar chart and the data can be updated, allowing the operation and maintenance personnel to intuitively see the error frequency trend of each key item and accurately grasp the weak links of the system; On the other hand, the operation and maintenance evaluation value is calculated, and the number of unqualified key items is comprehensively considered. Based on the comparison result between the operation and maintenance evaluation value and the preset operation and maintenance evaluation threshold, it is decided whether to trigger the operation and maintenance instruction. When the operation and maintenance evaluation value exceeds the standard, staff are dispatched in time to investigate and repair, so as to improve the quality of information reading.

[0020] The charging module is used to calculate the toll of the target vehicle based on the driving information received, and detect whether it is a vehicle registered in the province. For vehicles registered in the province, the maximum amount limit threshold is matched according to the vehicle type to determine whether the toll exceeds the limit. If it exceeds the limit, the toll is recharged. The specific process is as follows: When the driving information of the target vehicle is received, the license plate number, vehicle type, section identification of the road passed through and the corresponding mileage of each identified section in the driving information are read; different vehicle types are preset with corresponding calculation rates at different section identifications; the vehicle type of the target vehicle and the section identification of the road passed through during its driving process are matched with the preset calculation rates set for different vehicle types at different section identifications one by one, and the corresponding rate when the target vehicle is driving on each section identification is output; the mileage of each identified section passed by the target vehicle is multiplied by the rate of the corresponding section identification, and these products are summed to obtain the toll of the target vehicle, which is recorded as the toll; The first two characters of the target vehicle's license plate number are compared with the first two characters of the license plate number of the province. If they are inconsistent, the target vehicle's toll is sent to the fee verification module; If they are consistent, the target vehicle is judged to be a vehicle registered in this province; it is preset that different types of vehicles registered in this province are all set with corresponding maximum amount limit thresholds, the vehicle type of the target vehicle is matched with the maximum amount limit threshold set for different types of vehicles registered in this province, the corresponding maximum amount limit threshold is output, and the target vehicle's sight-to-sight fee is compared with the corresponding maximum amount limit threshold. If the target vehicle's sight-to-sight fee is less than or equal to the corresponding maximum amount limit threshold, the target vehicle's sight-to-sight fee is sent to the fee verification module; if the target vehicle's sight-to-sight fee is greater than the corresponding maximum amount limit threshold, the billing discount process is started; The specific implementation process of the re-billing process is as follows: For each target vehicle, the historical tolls, number of passes and toll evasion records of the target vehicle are extracted from the database according to the license plate number of the target vehicle, and the total toll amount TA, the total number of passes TC and the total number of toll evasion records TF are calculated. Different types of vehicles registered in the province are preset to have corresponding rate coefficients. The vehicle type of the target vehicle is matched with the rate coefficients set for different types of vehicles registered in the province, and the rate coefficient FX corresponding to the target vehicle is output; The toll amount TA, the total number of toll passes TC, the total number of toll evasion records TF and the rate coefficient FX of the target vehicle are normalized and then input into the preset formula: YHF=(TA×b1+TC×b2-TF×b3)×FX to obtain the rate discount coefficient YHF, wherein b1, b2 and b3 are preset weight coefficients, and different types of vehicles are preset with corresponding maximum rate discount coefficients. The vehicle type of the target vehicle is matched with the preset maximum rate discount coefficient corresponding to different types of vehicles, and the corresponding maximum discount coefficient is output. The rate discount coefficient of the target vehicle is compared with the corresponding maximum rate discount coefficient. If the rate discount coefficient of the target vehicle is greater than the corresponding maximum rate discount coefficient, the maximum discount coefficient corresponding to the target vehicle is used as the discount coefficient of the target vehicle. The discount amount is obtained by multiplying the target vehicle's initially calculated toll by the target vehicle's discount coefficient, and the target vehicle's initially calculated toll is subtracted from the discount amount to obtain the updated toll of the target vehicle, and the updated toll is sent to the fee verification module.

[0021] It should be noted that the license plate number, vehicle type, road section identification and mileage in the target vehicle's driving information are read as a basis, combined with the rate system for different vehicle types on each road section, to calculate the toll, which is in line with the actual cost and resource consumption, and effectively safeguards the interests of both the operator and the vehicle owner; By comparing the first two characters of the license plate number, it is possible to quickly and accurately determine whether the vehicle is registered in the province. For vehicles registered in the province, the maximum amount limit threshold is matched according to the vehicle type, effectively preventing vehicles registered in the province from being overcharged due to special circumstances. While ensuring the recovery of road operating costs, it provides certain cost guarantees for vehicle owners in the province. At the same time, with the help of the vehicle's historical tolls, number of passes and evasion records stored in the database, combined with the preset rate coefficient for vehicles registered in the province, the re-billing process is initiated for vehicles registered in the province that may be overcharged. The vehicle's past behavior is comprehensively considered to achieve personalized and rational charging and avoid "one-size-fits-all" charging. By calculating the rate discount coefficient and comparing it with the maximum rate discount coefficient, it is ensured that the discount range is in line with the actual situation of the vehicle and is within a controllable range. This not only guarantees operating profits, but also allows car owners to truly feel the reasonable concessions, improves car owner payment satisfaction, and reduces charging disputes.

[0022] Database: For each vehicle, the vehicle license plate number is used as an index to establish a repository. When a vehicle enters the highway from a toll station, the time the vehicle enters and exits the highway toll station, the entry and exit toll station numbers, and the CPC card number when entering the toll station are recorded and stored in the corresponding repository. At the same time, the toll generated by each vehicle passage, the number of passages, and the toll evasion record are stored.

[0023] The verification module verifies the legality of the toll rate; based on the minimum rate standard marked on each road section for different vehicle types and the mileage of the target vehicle, the minimum toll is calculated. With this as a reference, abnormal vehicles with too low tolls are screened, and their license plate numbers are promptly pushed to the monitoring center for manual verification. At the same time, for vehicles whose tolls have passed the legality verification, the online billing verification process is started, and data is exchanged with the online billing system of the networked toll center at high speed. The feedback toll receivable amount is compared with the toll calculated locally. According to the relationship between the toll deviation value and the threshold, the toll is directly transferred to the payment processing module, or the network troubleshooting process is triggered. The specific process is as follows: Rate legitimacy verification: Different vehicle types are preset with minimum rates at different road section signs. According to the target vehicle's driving path, the mileage of each marked road section passed by the target vehicle is multiplied by the minimum rate of the road section sign corresponding to its corresponding vehicle type, and these products are summed up to obtain the minimum toll for the target vehicle, which is recorded as the minimum toll for each section. The target vehicle's toll is compared with the minimum toll for each section. If the target vehicle's toll is less than the minimum toll for each section, the vehicle is marked as a vehicle with abnormal toll billing, and the license plate number of the vehicle with abnormal toll billing is sent to the monitoring center of the exit toll station. After the monitoring center receives the license plate number information of the vehicle with abnormal toll billing, the staff guides the vehicle with abnormal toll billing to a special inspection area for offline manual toll inspection. Online billing verification: If the toll of the target vehicle is greater than or equal to the minimum toll, the verification module will establish a high-speed data exchange channel with the online billing system of the highway network toll collection center, and send the vehicle type, license plate number, entrance toll station number, section identification, mileage of the identified section, and exit toll station number of the target vehicle to the online billing system; after receiving the toll amount feedback from the online billing system, the toll is subtracted from the toll of the target vehicle and the absolute value is taken to obtain the toll deviation value, and the toll deviation value threshold is preset. If the toll deviation value is less than or equal to the corresponding threshold, the toll is sent to the payment processing module; If the fee deviation value is greater than the corresponding threshold, a network troubleshooting information is generated and sent to the highway network operation and maintenance end. The highway network operation and maintenance end dispatches staff to conduct self-inspection and self-correction to check whether the local system data update is lagging, and whether there is data loss or error during network transmission; and make precise adjustments in a timely manner based on the troubleshooting results, such as automatically triggering local rate data updates and re-verification to ensure the accuracy and consistency of charges.

[0024] It should be noted that the toll legality check: by strictly setting the minimum toll rate for different types of vehicles on each road section, and accurately calculating the minimum toll for the target vehicle based on its actual driving path, a clear bottom line is set for the toll collection, just like setting up a strict filter in the toll collection process, preventing any vehicle with unreasonably low tolls from slipping through, thus protecting the fair rights and interests of the majority of normal toll-paying car owners and avoiding an imbalance in the overall toll rate caused by individual vehicles evading tolls; Online billing verification: For vehicles that have passed the legality verification of the toll, a high-speed interactive channel is established with the online billing system of the networked toll collection center to share all-round information of the target vehicle in real time, including key data such as vehicle type and driving route, and quickly compare the feedback of the toll receivable amount with the locally calculated toll. This process realizes cross-system data collaborative verification, fully utilizes the massive data and powerful computing power of the networked center, improves the accuracy of local toll collection, and reduces billing deviations caused by regional and system differences. Flexible decisions are made based on the relationship between the fee deviation value and the threshold. When the fee deviation value exceeds the standard, the network troubleshooting process is automatically triggered, prompting operation and maintenance personnel to conduct in-depth self-inspection and self-correction, accurately locate the root causes of problems such as local system data update lags and network transmission errors, and make timely adjustments, such as automatically updating local rate data and re-calibrating. This enables the verification module to dynamically adapt to changes and self-repair and improve, always ensuring the stable operation of the charging system and accurate billing in complex environments.

[0025] Payment processing module Payment QR codes are placed in conspicuous positions on both sides of the toll lane, and a display is installed adjacent to them. When a vehicle slowly enters the toll lane, the camera above the display quickly captures the license plate number of the target vehicle, and then accurately matches and displays the corresponding toll for the vehicle based on the license plate number; the driver follows the instructions to scan the payment QR code to complete the payment operation, and the moment the payment is successful, the voice prompt system in the control toll booth reminds the driver to return the CPC card; the driver inserts the CPC card into the card reader, and compares the CPC card number of the inserted card with the CPC card number of the vehicle with the corresponding license plate number pre-recorded in the database to see if they match; if the two match, the control lane guardrail is automatically lifted, allowing the vehicle to quickly leave the toll lane, and at the same time the vehicle's toll is sent to the database for storage and the number of vehicle passes is updated; if they do not match, the display screen in the control toll booth pops up a prompt "CPC card information is incorrect, please contact staff for processing", and at the same time sends an offline verification notice to the staff to ensure that on-site problems are properly resolved and the toll collection process is smooth and rigorous.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
