Description

Technical Field

[0001] The present invention relates to the field of highway communication technology, and in particular to a highway CPC card management method and system. Background Art

[0002] Electronic Toll Collection (ETC) and Compound Pass Card (CPC) toll collection are currently the two most important toll collection methods on domestic highways. They are primarily implemented using ETC gantry (gantry) technology, based on 5.8GHz dedicated short-range communications (DSRC) technology, to identify ETC and manual semi-automatic toll collection vehicles and implement segmented billing. CPC cards are used by non-ETC vehicles in manual toll lanes and have 13.56MHz and 5.8GHz communication capabilities, capable of reading and writing the vehicle's route information. CPC cards need to be activated at the highway entrance to exchange information with the ETC gantry via 5.8GHz microwaves. Furthermore, the vehicle's highway entrance and exit information, route information, and vehicle identity information can be written to the CPC card in encrypted form. Therefore, the vehicle's route information can be read at the highway exit for unified manual payment.

[0003] However, in daily highway operations, CPC cards issued to vehicles at the entrance may not be returned at the exit, resulting in some CPC cards being lost. There is currently no effective way to confirm CPC card loss, other than proactively reporting it. Consequently, it's difficult to accurately understand CPC card circulation within the road network, determine the cause of CPC card loss, and identify accountability. Therefore, a management method for identifying lost CPC cards is urgently needed to accurately determine who is responsible for the loss. Summary of the Invention

[0004] In view of this, an embodiment of the present invention provides a method and system for managing CPC cards on a highway to solve the problem of accurately identifying lost CPC cards.

[0005] One aspect of the present invention provides a method for managing a highway CPC card, the method comprising the following steps:

[0006] Obtain CPC card record data at the expressway entrance, and based on the obtained CPC card record data at the expressway entrance, record the status of the corresponding CPC card in the CPC card management library as the usage status; wherein the CPC card record data at the expressway entrance includes the following fields: CPC card number, vehicle identification information bound to the CPC card number, expressway entrance number, and recording time of the CPC card at the expressway entrance;

[0007] Obtain CPC card flow data and CPC card record data at highway exits, and update the status of the corresponding CPC card in the CPC card management library based on the obtained CPC card record data at highway exits; wherein the CPC card flow data includes the following fields: CPC card number, gantry number communicating with the CPC card, and communication time information; and the CPC card record data at highway exits includes the following fields: CPC card number, vehicle identification information bound to the CPC card number, highway exit number, and recording time of the CPC card at the highway exit;

[0008] For each CPC card in use in the CPC card management library, the time interval between a specific time point on the expressway and the current time is determined. If the determined time interval is greater than a set threshold, the CPC card in use is determined to be lost, and the status of the CPC card determined to be lost is updated to lost in the CPC card management library. The specific time point is the time each CPC card in use is recorded at the expressway entrance or the last communication time between the gantry and each CPC card in use.

[0009] Based on the flow data of the CPC card that is determined to be lost, the gantry number that last communicated with the CPC card that is determined to be lost is obtained, the area to which the gantry belongs is determined according to the gantry number of the last communication, the area to which the gantry that last communicated with the CPC card that is determined to be lost belongs is determined as the responsibility area, and a responsibility-determined card loss record is generated; wherein, the responsibility-determined card loss record includes the following fields: the number of the lost CPC card, the responsibility area, the vehicle identification information bound to the number of the lost CPC card, the number of the last highway entrance, the number of the gantry that last communicated with the lost CPC card, and the corresponding communication time.

[0010] In some embodiments of the present invention, the CPC card management library includes the following fields: the CPC card number, the CPC card status corresponding to the CPC card number, and the CPC card location; wherein, the CPC card status corresponding to the CPC card number is updated in real time based on the CPC card record data at the highway entrance and the CPC card record data at the highway exit, and the CPC card location is updated in real time based on the CPC card record data at the highway entrance, the CPC card flow data, and the CPC card record data at the highway exit.

[0011] In some embodiments of the present invention, based on the acquired CPC card record data of the highway entrance, the status of the corresponding CPC card in the CPC card management library is recorded as the usage status, including:

[0012] The CPC card number in the CPC card record data of the expressway entrance obtained in real time is matched with the CPC card number in the CPC card management library, and the status of the CPC card matched in the CPC card management library is changed to the use status.

[0013] In some embodiments of the present invention, updating the status of the corresponding CPC card in the CPC card management library based on the acquired CPC card record data of the highway exit includes:

[0014] The CPC card number in the CPC card record data of the expressway exit obtained in real time is matched with the number of the CPC card in use in the CPC card management library, and the status of the CPC card matched in the CPC card management library is changed from the use status to another status.

[0015] In some embodiments of the present invention, for each CPC card in use in a CPC card management library, determining a time interval between a specific time point on the highway and the current time, and determining that the CPC card in use is lost if the determined time interval is greater than a set threshold, includes:

[0016] For each CPC card in use in the CPC card management library, determine the time interval between the recording time of each CPC card at the highway entrance and the current time, and determine that the CPC card is lost if the determined time interval is greater than a set threshold; or

[0017] For each CPC card in use in the CPC card management library, the time interval between the last communication time between the gantry and each CPC card in use and the current time is determined, and the CPC card is determined to be lost if the determined time interval is greater than the set threshold; in the case that some CPC cards are missing flow data, the recording time of the highway entrance is used as the last communication time between the gantry and the CPC card that is missing flow data.

[0018] In some embodiments of the present invention, obtaining the gantry number of the last communication with the CPC card determined to be lost based on the flow data of the CPC card determined to be lost includes:

[0019] Acquire all gantry numbers that communicate with the CPC card that is determined to be lost based on the CPC card's flow data, and acquire the gantry number that last communicated with the CPC card that is determined to be lost based on a pre-stored gantry topology relationship; or

[0020] The last communication time between the gantry and the CPC card that is determined to be lost is obtained based on the flow number of the CPC card, and the gantry number that last communicated with the CPC card that is determined to be lost is obtained based on the last communication time.

[0021] In some embodiments of the present invention, the method further comprises:

[0022] The vehicle corresponding to the vehicle identification information bound to the number of the lost CPC card is determined as the responsible vehicle. If the number of CPC cards corresponding to the current responsible vehicle lost within the set time exceeds the set vehicle threshold, the responsible vehicle is determined as an abnormal vehicle.

[0023] In some embodiments of the present invention, based on the flow data of the CPC card that is determined to be lost, the gantry number with which the CPC card last communicated is obtained, the area to which the gantry belongs is determined based on the gantry number with which the CPC card last communicated, the area to which the gantry last communicated with the CPC card that is determined to be lost belongs is determined as the responsible area, and a record of the lost card with a determined responsibility is generated, including:

[0024] If the last communication time between the CPC card and the gantry is within the free passage period of the expressway, and the time interval between the recording time of the expressway entrance and the last communication time with the gantry is not greater than the set free threshold, then the CPC card that is determined to be lost is a free CPC card; otherwise, the CPC card that is determined to be lost is a non-free CPC card.

[0025] For non-free CPC cards, the gantry number that last communicated with the non-free CPC card is obtained based on the non-free CPC card's transaction data. The area to which the gantry belongs is determined based on the last communicated gantry number. The area to which the gantry last communicated with the non-free CPC card belongs is determined as the responsible area, and a record of the lost card is generated.

[0026] For free CPC cards, the number of free CPC cards in each area and the average traffic volume in each area during the free highway passage period are counted, and the number of free CPC cards in each area is redistributed based on the proportion of the average traffic volume in each area during the free highway passage period; the area to which each free CPC card is allocated is determined as the responsibility area of ​​the free CPC card, and a record of lost card responsibility is generated.

[0027] Another aspect of the present invention provides a highway CPC card management system, comprising a processor and a memory, wherein the memory stores computer instructions, and the processor is used to execute the computer instructions stored in the memory. When the computer instructions are executed by the processor, the system implements the steps of the method described in any of the above embodiments.

[0028] Another aspect of the present invention provides a computer-readable storage medium having a computer program stored thereon, which implements the steps of the method described in any one of the above embodiments when the program is executed by a processor.

[0029] The highway CPC card management method and system of the present invention can identify whether a CPC card is lost based on the time the CPC card has been in transit in the road network, and can also clarify the responsibility for the loss of the CPC card, thereby significantly reducing the number of card losses, improving the service quality of road network operations, and ensuring the normal and orderly development of networked toll collection operations.

[0036] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and the accompanying drawings. Here, the exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0037] It should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, the accompanying drawings only show structures and / or processing steps closely related to the solutions according to the present invention, while other details that are not closely related to the present invention are omitted.

[0038] It should be emphasized that the term "include / comprises" when used herein refers to the existence of features, elements, steps or components, but does not exclude the existence or addition of one or more other features, elements, steps or components.

[0039] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the accompanying drawings, the same reference numerals represent the same or similar components, or the same or similar steps.

[0040] At present, there are situations where CPC cards are sent at the highway entrance but cannot be recovered at the highway exit, resulting in the loss of CPC cards. The loss of CPC cards may involve various reasons such as toll collection, card management and system operation. Therefore, except for the drivers and passengers who actively inform the CPC of the loss, it is difficult to identify other lost CPC cards and to hold them accountable in the future, which is not conducive to the healthy development of the road network operation industry.

[0041] Based on this, an embodiment of the present invention provides a method for managing CPC cards on highways. Based on CPC card transaction data and CPC card record data at highway entrances and exits, the method determines whether a CPC card is lost by comparing the last identification time of a CPC card in use with the current time, and further generates a record of lost cards. This method can clearly identify lost CPC cards and the cause of loss, allowing accountability for lost cards. It also accurately calibrates the CPC card circulation across the entire road network and the number of CPC cards in each area.

[0042] Figure 1 FIG. 1 is a flow chart of a method for managing a highway CPC card according to an embodiment of the present invention. Figure 1 The method shown may specifically include steps S110 to S140.

[0043] Step S110: Obtain CPC card record data at the highway entrance, and based on the obtained CPC card record data at the highway entrance, record the status of the corresponding CPC card in the CPC card management library as the usage status; wherein the CPC card record data at the highway entrance includes the following fields: CPC card number, vehicle identification information bound to the CPC card number, highway entrance number, and recording time of the CPC card at the highway entrance.

[0044] In some embodiments of the present invention, based on the acquired CPC card record data of the highway entrance, the status of the corresponding CPC card in the CPC card management library is recorded as the usage status, including:

[0045] The CPC card numbers included in the CPC card record data of the expressway entrance acquired in real time are matched with the CPC card numbers included in the CPC card management library, and the status of the CPC card matched in the CPC card management library is changed to the use status.

[0046] More specifically, non-ETC vehicles must obtain an activated CPC card at the highway entrance. This card then communicates with the gantry during subsequent highway travel, recording the vehicle's route and toll information. The toll amount on the card is then read at the highway exit to complete toll collection. Therefore, records of CPC card issuance and activation are stored at the highway entrance, representing the CPC card record data at the highway entrance. If CPC cards can be automatically recognized by card readers at highway entrances, this CPC card record data at highway entrances can be obtained in real time.

[0047] Furthermore, the status of the corresponding CPC card in the CPC card management library can be modified based on real-time CPC card record data at the highway entrance. When the CPC card record data at the highway entrance is updated (i.e., when a vehicle passes through the highway entrance and obtains a CPC card), the status of the CPC card corresponding to the CPC card number in the CPC card management library is recorded as in use, based on the CPC card number included in the updated CPC card record data at the highway entrance. In other words, when a passing vehicle obtains an activated CPC card at the highway entrance, the status of the activated CPC card in the CPC card management library is simultaneously changed to in use, the position of the CPC card also changes accordingly, and the identification information of the corresponding passing vehicle is stored in the activated CPC card.

[0048] CPC card records at highway entrances include the following fields: CPC card number, vehicle identification information associated with the CPC card number, corresponding highway entrance and exit number, entrance and exit identification time, entrance shift, entrance toll network number, and entrance toll collector number. The vehicle identification information associated with the CPC card number includes the following fields: vehicle model, license plate number, license plate color, entrance toll lane number, vehicle type, number of truck axles, gross truck weight, approved load capacity, and special truck information.

[0049] In some embodiments of the present invention, the CPC card management library includes information of the following fields: CPC card number, CPC card status corresponding to the CPC card number, the number of CPC cards and the location of the CPC card; wherein, the CPC card status corresponding to the CPC card number is updated in real time based on the CPC card record data at the highway entrance and the CPC card record data at the highway exit, and the CPC card location is updated in real time based on the CPC card record data at the highway entrance, the CPC card flow data and the CPC card record data at the highway exit.

[0050] For example, CPC card states include: in-use, unused, damaged, written-off, compensated, and lost. The in-use state refers to the state in which an activated CPC card is still communicating with the ETC gantry under normal use. The unused state refers to the state in which the CPC card has not been activated and fully preserved at the highway entrance. The damaged state refers to the state in which the CPC card is unusable and not damaged by the user. The written-off state refers to the state in which the CPC card is discarded. The compensated state refers to the state in which the user damages or loses the CPC card during travel and pays compensation. The lost state refers to the state in which the CPC card is activated at the highway entrance but its whereabouts cannot be determined. Each CPC card can only be marked with one CPC card state at a time. Therefore, the state of the corresponding CPC card in the CPC card management library can be changed from unused to in-use based on real-time CPC card record data at the highway entrance.

[0051] For example, the number of CPC cards includes: CPC card inventory, CPC card in-transit, and CPC card circulation. The inventory refers to the number of CPC cards stored in the CPC card warehouse and at all expressway entrances and exits. The in-transit number refers to the number of CPC cards currently on the expressway that can communicate with the ETC gantries (this may include CPC cards managed in the same area and those managed in other areas). The circulation number is the sum of the inventory and in-transit numbers.

[0052] For example, CPC card locations include: highway entrances, highway exits, access zones, and CPC card storage warehouses. When a CPC card is not in use, data recorded by CPC cards at highway entrances and exits can be used to determine whether the CPC card is stored at a highway entrance, exit, or CPC card storage warehouse. When a CPC card is in use, its current zone or specific location can be determined through communication with the gantry based on CPC card flow data.

[0053] As an example, the CPC card management library manages CPC cards on a provincial basis. Therefore, the number of CPC cards included in the CPC card management library of Province A refers to the number of CPC cards held in Province A, the number of CPC cards in transit managed by Province A, and the circulation volume of CPC cards in Province A.

[0054] Step S120: Obtain the CPC card's flow data and the CPC card record data of the highway exit, and update the status of the corresponding CPC card in the CPC card management library based on the obtained CPC card record data of the highway exit; wherein, the CPC card's flow data includes the following fields: CPC card number, gantry number communicating with the CPC card, and communication time information; the CPC card record data of the highway exit includes the following fields: CPC card number, vehicle identification information bound to the CPC card number, highway exit number, and recording time of the CPC card at the highway exit.

[0055] In some embodiments of the present invention, updating the status of the corresponding CPC card in the CPC card management library based on the acquired CPC card record data of the highway exit includes:

[0056] The CPC card number included in the CPC card record data of the highway exit obtained in real time is matched with the number of the CPC card in use in the CPC card management library, and the status of the CPC card matched in the CPC card management library is changed from the use status to another status.

[0057] More specifically, the ETC gantries and non-ETC vehicles carrying CPC cards exchange information via 5.8GHz. The ETC gantries generate CPC card transaction data for each passing vehicle and upload it to the ETC gantry system. This data is then available from the ETC gantry system for a specific time interval. Non-ETC vehicles carrying CPC cards are required to return their CPC cards at highway exits and pay tolls based on the card balance. Therefore, records of CPC card return and payment are stored at highway exits, representing CPC card record data at highway exits.

[0058] For example, CPC card records at highway exits are collected in real time and the corresponding CPC card status and location in the CPC card management database are modified. When a passing vehicle returns an activated CPC card at a highway exit, the CPC card status in the CPC card management database changes from being used to being a different type of CPC card.

[0059] For example, the ETC gantry communicates with passing vehicles (ETC vehicles and non-ETC vehicles carrying CPC cards) via microwaves at 5.8GHz. Therefore, the ETC gantry system stores both ETC and CPC card transaction data, which can be distinguished by access ID, MAC address, etc. CPC card transaction data includes information in the following fields: CPC card number, access ID, billing transaction number, billing amount, billing mileage, vehicle identification information tied to the CPC card number, gantry number communicating with the CPC card, gantry type, gantry region, and communication time information.

[0060] The CPC card record data at a highway exit includes the following fields: CPC card number, vehicle identification information associated with the CPC card number, highway exit number, and the time the CPC card was recorded at the highway exit. The CPC card record data at a highway exit includes the same fields as the CPC card record data at a highway entrance.

[0061] For example, if a CPC card is damaged or lost, it cannot be automatically recognized by the card reader at the highway exit. Vehicle tolls must be calculated and collected through other billing methods, such as online billing or minimum-amount billing, and the current CPC card status and location must be manually recorded. Therefore, the CPC card record data at the highway exit referred to in this invention includes both data automatically recorded by the CPC card reader at the exit and data manually recorded when the CPC card is used at the exit. In other words, the CPC card record data at the highway exit includes all CPC cards registered at the highway exit.

[0062] The field information included in the CPC card flow data, CPC card management library, CPC card record data at highway entrances, and CPC card record data at highway exits mentioned in the present invention is only an example. The present invention is not limited thereto and may also include information of other fields.

[0063] Step S130: For each CPC card in use in the CPC card management library, determine the time interval between its specific time point on the highway and the current time. If the determined time interval is greater than a set threshold, determine that the CPC card in use is lost, and update the status of the CPC card determined to be lost to a lost status in the CPC card management library; wherein the specific time point is the recording time of each CPC card in use at the highway entrance or the last communication time between the gantry and each CPC card in use.

[0064] In some embodiments of the present invention, for each CPC card in use in a CPC card management library, determining a time interval between a specific time point on the highway and the current time, and determining that the CPC card in use is lost if the determined time interval is greater than a set threshold, includes:

[0065] For each CPC card in use in the CPC card management library, determine the time interval between the recording time of each CPC card at the highway entrance and the current time, and determine that the CPC card is lost if the determined time interval is greater than a set threshold; or

[0066] For each CPC card in use in the CPC card management library, determine the time interval between the last communication time between the gantry and each CPC card in use and the current time. If the determined time interval is greater than a set threshold, the CPC card is determined to be lost. If some CPC cards are missing transaction data, the recorded time at the highway entrance is used as the last communication time between the gantry and the CPC card with missing transaction data.

[0067] If the determined time interval is not greater than the set threshold, it is determined that the CPC card is still in use and has not been lost.

[0068] More specifically, since CPC cards are issued to passing vehicles at highway entrances, the loss of each CPC card in use in the CPC card management library can be determined by comparing the time interval between the CPC card's entry recording time and the current verification time, as included in the CPC card's recorded data at the highway entrance. Based on whether the time interval exceeds a first set threshold, the loss of each CPC card in use in the CPC card management library can be determined. Furthermore, since CPC cards communicate and identify with the ETC gantry during highway travel, the last communication time between each CPC card in use in the CPC card management library and the ETC gantry can be obtained based on the CPC card's flow data. Based on whether the time interval between the gantry's last communication time and the current verification time exceeds a second set threshold, the loss of each CPC card can be determined. Upon determining that a CPC card is lost, the status of the CPC card determined to be lost is updated from in use to lost in the CPC card management library.

[0069] Furthermore, when determining whether each CPC card is lost based on the time interval between the last communication time of the gantry and the current verification time, there may be a situation where some vehicles do not have CPC card transaction data (i.e., the data of communication between the CPC card and the ETC gantry is not included). Therefore, it is possible to determine whether the CPC card is lost by comparing the recording time of the CPC card with missing transaction data at the highway entrance (i.e., using the recording time of the CPC card at the highway entrance to replace the last communication time between the gantry and the CPC card) and the current verification time to see whether the time interval is greater than the first set threshold or the second set threshold.

[0070] As an example, the first threshold value may be less than or equal to the second threshold value. For example, if the time interval between the recording time of a CPC card at the highway entrance and the current time is greater than 30 days (assuming the first threshold value is 30 days), the CPC card is determined to be lost; or if the time interval between the last communication time between a CPC card and the gantry and the current time is greater than 40 days (assuming the second threshold value is 40 days), the CPC card is determined to be lost.

[0071] As an example, if some CPC cards in use do not have transaction data, all CPC cards will directly use the recorded time of the entry for comparison.

[0072] Step S140: Based on the flow data of the CPC card that is determined to be lost, the gantry number that last communicated with the CPC card that is determined to be lost is obtained, the area to which the gantry belongs is determined according to the gantry number of the last communication, the area to which the gantry that last communicated with the CPC card that is determined to be lost belongs is determined as the responsibility area, and a responsibility-determined card loss record is generated; wherein, the responsibility-determined card loss record includes the following fields: the number of the lost CPC card, the responsibility area, the vehicle identification information bound to the number of the lost CPC card, the number of the last highway entrance, the number of the gantry that last communicated with the lost CPC card, and the corresponding communication time.

[0073] In some embodiments of the present invention, obtaining the gantry number of the last communication with the CPC card determined to be lost based on the flow data of the CPC card determined to be lost includes:

[0074] Obtaining all gantry numbers that communicate with the CPC card that is determined to be lost from the CPC card's flow data, and obtaining the gantry number that last communicated with the CPC card that is determined to be lost based on a pre-stored gantry topology relationship; or

[0075] The last communication time between the gantry and the CPC card that is determined to be lost is obtained from the CPC card flow data, and the gantry number that last communicated with the CPC card that is determined to be lost is obtained based on the last communication time.

[0076] Furthermore, all gantry information (including gantry number, gantry type, corresponding communication time, gantry area, previous gantry number, previous gantry communication time and other field information) that communicates with the CPC card currently determined to be lost can be obtained from the CPC card's flow data in a certain period of time (for example, the period from the recording time of the high-speed entrance of the CPC card currently determined to be lost to the current verification time). Based on the obtained gantry number and the pre-stored gantry topology, the path information of the CPC card can be clarified, and thus the gantry information that last communicated with the CPC card currently determined to be lost can be determined. Or

[0077] According to the number of the CPC card currently determined to be lost, the gantry information corresponding to the CPC card (including field information such as the gantry number, gantry type, corresponding communication time, the area to which the gantry belongs, the number of the previous gantry and the communication time of the previous gantry) is filtered out from the CPC card flow data. After further filtering by the communication time, the gantry information of the last communication with the CPC card determined to be lost can be obtained.

[0078] For example, each area includes many communication gantries, and the gantries can be distinguished by gantry numbers, so the area to which the gantry belongs can be determined by the gantry number.

[0079] As an example, if the identification device corresponding to the last identification time of a CPC card is an ETC gantry, the last identification gantry information of the CPC card can be obtained from the CPC card transaction data; if the identification device corresponding to the last identification time of a CPC card is a highway entrance, the highway entrance information of the CPC card can be obtained from the CPC card transaction data.

[0080] In some embodiments of the present invention, based on the flow data of the CPC card that is determined to be lost, the gantry number with which the CPC card last communicated is obtained, the area to which the gantry belongs is determined based on the gantry number with which the CPC card last communicated, the area to which the gantry last communicated with the CPC card that is determined to be lost belongs is determined as the responsible area, and a record of the lost card with a determined responsibility is generated, including:

[0081] If the last communication time between the CPC card and the gantry is within the free passage period of the expressway, and the time interval between the recording time of the expressway entrance and the last communication time with the gantry is not greater than the set free threshold, then the CPC card that is determined to be lost is a free CPC card; otherwise, the CPC card that is determined to be lost is a non-free CPC card.

[0082] For non-free CPC cards, the gantry number that last communicated with the non-free CPC card is obtained based on the non-free CPC card's transaction data. The area to which the gantry belongs is determined based on the last communicated gantry number. The area to which the gantry last communicated with the non-free CPC card belongs is determined as the responsible area, and a record of the lost card is generated.

[0083] For free CPC cards, the number of free CPC cards in each area and the average traffic volume in each area during the free highway passage period are counted, and the number of free CPC cards in each area is redistributed based on the proportion of the average traffic volume in each area during the free highway passage period; the area to which each free CPC card is allocated is determined as the responsibility area of ​​the free CPC card, and a record of lost card responsibility is generated.

[0084] As an example, for free CPC cards, the total number of free CPC cards within the set range is counted (assuming that the set range involves only three provinces, 3 CPC cards were actually lost in Province A, 3 were actually lost in Province B, and 0 were actually lost in Province C, for a total of 6 CPC cards lost) and the average traffic volume in each region (assuming that the average traffic volume in Provinces ABC is 150 vehicles / hour, 300 vehicles / hour, and 450 vehicles / hour respectively); based on the ratio of the average traffic volume in each region (A:B:C=1:2:3), the number of lost CPC cards in each region is redistributed (redistributed as: 1 lost in Province A, 2 lost in Province B, and 3 lost in Province C), and a record of lost cards with fixed responsibilities is generated. In addition, the numbers of lost CPC cards can be randomly assigned, or the management area of ​​the CPC card can be prioritized (for example, two CPC cards are selected from the 3 cards in Province A and assigned to Province C).

[0085] For non-free CPC cards, the last communication gantry information (including gantry number, communication time and gantry position, etc.) is determined based on the transaction data of the non-free CPC card, the area to which the last communication gantry belongs is determined as the responsibility area, and a record of card loss is generated and sent to the responsibility area.

[0086] The CPC cards confirmed to be lost include free CPC cards and non-free CPC cards.

[0087] The area to which the gantry belongs and the area of ​​responsibility can be an administrative division such as a province or city, or a custom area, such as within a 10-meter radius of the gantry.

[0088] The responsibility-based lost card record includes information in the following fields: the number of the lost CPC card, the responsible area, the responsible vehicle identification information (including license plate number, vehicle model, vehicle weight, vehicle type and license plate color, etc.), the number and type of the gantry with which the lost CPC card last communicated, and the corresponding communication time.

[0089] In some embodiments of the present invention, the method further comprises:

[0090] The vehicle corresponding to the vehicle identification information bound to the number of the lost CPC card is determined as the responsible vehicle. If the number of CPC cards corresponding to the current responsible vehicle lost within the set time exceeds the set vehicle threshold, the responsible vehicle is determined as an abnormal vehicle.

[0091] Furthermore, each CPC card is encrypted with vehicle identification information. Therefore, the serial number of a confirmed lost CPC card can be mapped to the license plate number, and the vehicle corresponding to that license plate number can be identified as the responsible vehicle. Therefore, if the number of CPC cards lost by a responsible vehicle exceeds a set threshold within a set timeframe or number of checks, the vehicle is identified as abnormal and further manually verified to determine if it is a toll evader. If so, appropriate measures such as traffic penalties can be taken to hold the vehicle accountable.

[0092] It should be noted that the lost CPC cards involved in step S140 are all CPC cards confirmed to be lost as mentioned in step S130, and are not CPC cards that were originally in a lost state in the CPC card management library.

[0093] As an example, CPC card flow data can be obtained from the national road network or from regional (e.g., provincial) road networks. When the CPC card flow data originates from the national road network, the entire CPC card path can be directly confirmed based on the last communication gantry, thereby determining the area of ​​responsibility. When the CPC card flow data originates from a regional road network, the area to which the CPC card is traveling can be determined based on the last communication gantry. However, the CPC card flow data for the area to which the CPC card is traveling is required to further determine the CPC card's path within that area, and the area of ​​responsibility cannot be directly determined.

[0094] As an example, the highway CPC card management method proposed in this invention can provide a channel for coordinated interactive processing between provinces. This includes: after generating a record of lost CPC cards, the record needs to be sent to the responsible region. Based on the CPC card record data at the responsible region's highway entrances and exits, as well as CPC card transaction data, the whereabouts of the lost CPC card can be further verified. For example, if a CPC card managed by Province A is confirmed to be lost in Province B, the record can be forwarded to Province B, which will then conduct further verification of the CPC card's whereabouts.

[0095] As an example, if area A determines that area B is the responsible area and sends a record of lost cards, and area B verifies that the lost CPC card was not lost in area B, then areas A and B can upload the CPC card whereabouts records of each area respectively, and manually arbitrate the process.

[0096] As an example, the record of card loss and special transaction flow can assist in analyzing audit business data. Special transaction flow includes a variety of vehicle payment methods such as online billing, minimum fee billing, shortest path billing and minimum hop billing (that is, billing the path with the least number of gantries for the corresponding vehicle) when the complete vehicle driving path cannot be obtained. Audit business data mainly includes checking card reversal, card scratching and vehicle evasion of fees. For example, the vehicles in the record of card loss and special transaction flow can be further checked to make the audit business data targeted. For example, if a vehicle appears more times in the record of card loss and special transaction flow, then the vehicle may be a fee evasion vehicle, and the audit business data can be updated.

[0097] For example, based on statistically determined card loss records, the cause of card loss can be identified by examining factors such as the standardization of toll collection operations, card management, and system operation, effectively reducing the number of card losses. Specifically, toll collection standardization can be assessed by examining the regularity of road maintenance (e.g., gaps in a certain section of road may result in a high number of CPC card loss records on that section) and the rationality of toll collection points. Card management standardization can be assessed by examining the operational records of card issuance and return at highway entrances and exits. For example, CPC cards may be returned to the warehouse but no operation records exist. Comparing operational records with card loss records can indirectly reflect operational standardization. System operation can be assessed by examining toll station data transmission (e.g., CPC cards may be stored but the toll station data is not uploaded), toll collection systems, gantry systems, and network failures. Regular CPC card loss verification not only allows for the identification of lost CPC cards but also provides timely information on issues in daily highway operations, ensuring the smooth and orderly operation of networked toll collection operations. In addition, it also includes a comprehensive analysis of CPC card loss records combined with special transaction flows and audit business data to locate the cause of card loss from aspects such as the standardization of charging business, card management standardization, and system operation status.

[0098] Figure 2 This is a flow chart of a method for managing CPC cards for highways according to another embodiment of the present invention. The method obtains CPC card record data at highway entrances and highway exits within a certain time interval (the time interval between a specific time point and the current time), and obtains lost CPC card information through screening and filtering. The specific steps are as follows:

[0099] Step S01: Obtain CPC card flow data, CPC card record data at highway entrances, and CPC card record data at highway exits.

[0100] Step S02: Select the last entry identification time and exit identification time corresponding to each CPC card from the CPC card record data at the highway entrance and the CPC card record data at the highway exit. If the last entry time is later than the last exit time, the CPC card is determined to be an in-transit CPC card.

[0101] Step S03: Determine the last gantry identification time of each CPC card in transit based on the flow data of the CPC card in transit. If the time interval between the last gantry identification time and the current verification time is greater than the set threshold, the CPC card is determined to be pre-lost.

[0102] Step S04: Determine whether the CPC card that is expected to be lost is a CPC card that is manually recorded as being in a compensation state or a damaged state. If not, determine that the CPC card is lost, and change the state of the corresponding CPC card in the CPC card management library to a lost state.

[0103] Step S05: Based on the CPC card's flow data, determine the last communication gantry information where the CPC card is lost, determine the area described by the last communication gantry as the responsibility area, and generate a responsibility-based card loss record.

[0104] For step S03, the CPC card record data at the highway entrance can also be used to determine whether the CPC card is pre-lost: based on the CPC card record data at the highway entrance of the CPC card in transit, the highway entrance record time of each CPC card in transit is determined. If the time interval between the highway entrance record time and the current verification time is greater than the set threshold, it is determined that the CPC card is pre-lost.

[0105] For example, if a CPC card is damaged or lost at a highway exit and cannot be used to change its status and pay vehicle fees using the card reader at the highway exit, the highway exit personnel can manually record the CPC card's status (from in-use status to damaged status or compensation status) and CPC card's location (recording the corresponding highway exit toll station name, road section, province, and other location information) in the CPC card management database, without recording it in the CPC card record data at the highway exit. In this case, step S04 may be: determining whether the CPC card that was lost is one of the CPC cards in the CPC card management database that is in compensation status or damaged status. If not, the CPC card is determined to be lost, and the status of the corresponding CPC card in the CPC card management database is changed to lost status.

[0106] As can be seen from the above, the highway CPC card management method proposed in this embodiment does not depend on the status of each CPC card in the CPC card management library. That is, the method does not require the CPC card to be activated to the use status at the highway entrance and changed from the use status to other status at the highway exit. Therefore, there is no need to establish a connection between the CPC card management library and the highway entrance and exit. However, the CPC card management library needs to establish a connection with the system file that stores CPC cards in the compensation status and the damaged status, and can regularly update the CPC card status in the CPC card management library based on the system file.

[0107] The highway CPC card management method proposed in the present invention has the following advantages:

[0108] 1. It can identify whether a CPC card is lost and solve the problem of determining responsibility for CPC card loss on national highways, accurately locate the responsibility, and coordinate responsibility determination and arbitration between different regions.

[0109] 2. It can accurately calibrate the CPC card circulation volume and CPC card holdings. Each region can promptly purchase the corresponding number of CPC cards based on the card loss situation to ensure the normal and orderly operation of networked charging.

[0110] 3. It reflects the possible problems in the standardization of highway network toll collection operations, CPC card management standardization, data upload and system operation, and can provide corresponding verification basis for audit business, improve the quality of network operation services, and promote the healthy development of the industry.

[0111] Corresponding to the above method, the present invention also provides a highway CPC card management system, which includes a computer device, the computer device includes a processor and a memory, the memory stores computer instructions, and the processor is used to execute the computer instructions stored in the memory. When the computer instructions are executed by the processor, the system implements the steps of the method described above.

[0112] Figure 3 The diagram below illustrates the relationship between the CPC card management system, the expressway entrance and exit recording system, and the ETC gantry system in one embodiment of the present invention. The expressway entrance recording system transmits CPC card record data from expressway entrances to the expressway CPC card management system in real time, changing the corresponding CPC card in the CPC card management library of the management system from unused to used. The expressway exit recording system transmits CPC card record data from expressway exits to the expressway CPC card management system in real time, changing the corresponding CPC card in the CPC card management library from used to unused, compensated, or damaged. The ETC gantry system can upload CPC card transaction data to the expressway CPC card management system, which can determine whether a CPC card is lost based on the CPC card transaction data and further generate a record of the lost card.
