In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the following embodiments and accompanying drawings. The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.

It should be emphasized that the term "comprises/comprising" when used herein, is taken to specify the presence of stated features, elements, steps or components, but does not preclude the presence or addition of one or more other features, elements, steps or components.

It is also noted herein that the term "coupled," if not specifically stated, may refer herein to not only a direct connection, but also an indirect connection in which an intermediate is present.

ETC is vigorously carried out in the current-stage highway passing, the highway toll collection process is simplified, and the highway passing speed is improved. The ETC users are divided into double-card users and single-card users, wherein the double-card users refer to vehicle users who are provided with vehicle-mounted labels (OBUs) and loaded with ETC user cards; whereas a single-card user refers to a user who does not have a car tag installed. In the traditional operation process, vehicles without ETC and ETC single-card users need to record the journey by means of paper passes and charge. After the project of canceling the holy-clean toll station on the expressway, which is developed by the transportation department, is started, a CPC card is gradually adopted as a pass card medium used by the expressway, and the CPC card has the functions of traditional passes and transaction with a portal antenna. Composite pass card, CPC card: the vehicle communication system integrates the communication functions of 5.8GHz and 13.56MHz, has the read-write functions of vehicle simulation entrance information, simulation path information, charging information and the like, and is a reusable passing medium which is distributed to the vehicle in an entrance lane of a toll station and recovered in an exit lane.

In the transaction process of the exit lane of the highway, the CPC card needs to pre-read transaction information recorded in the card through a transaction antenna of the exit lane, such as entrance lane information, vehicle model information, simulated path information and the like, so as to provide a basis for charging. However, with the large-scale operation and use of the CPC card, the pre-reading obstacles and faults occur on part of the CPC cards. In order to guarantee smooth highway traffic, the pre-reading function of the CPC card needs to be tested, and a method for quickly and effectively detecting the pre-reading function of the CPC card does not exist in the prior art.

Therefore, the invention provides a test method for a pre-reading mechanism of a CPC card, which is used for detecting whether the pre-reading function of the CPC card is normal or not and ensuring the completeness of the CPC function so as to prevent transaction failure.

The CPC card is mainly used for recording highway entrance lane information, simulated vehicle information and simulated path information and for charging at a highway exit. Specifically, at the entrance of the highway, a worker distributes a CPC card and writes corresponding simulated vehicle information and entrance lane information into the CPC card through a card reader, and when the CPC card passes through a portal antenna in the driving process of the vehicle, the portal antenna writes simulated path information; when the CPC card is returned from the exit lane of the expressway, the transaction information in the card is quickly read by the transaction antenna, and the transaction fee amount is calculated for charging.

In order to simulate a real use scene of the CPC card and meet the requirement for quick and simple detection, as shown in fig. 2, the test method in this embodiment adopts an integrated test device 120 including a 13.56MHz card reader, a 5.8GHz antenna and a main control module to perform detection, the integrated test device 120 is connected to an upper computer 110, and the 13.56MHz card reader and the 5.8GHz antenna are controlled by the main control module to read and write the CPC card 130, as shown in fig. 1, the method includes steps S101 to S106.

It should be noted that, in this embodiment, the description of steps S101 to S106 does not limit the order of the steps, and it should be understood that, in a specific usage scenario, some steps may be parallel or the order may be changed. In this embodiment, the main control module is used as a main body, and the main control module may be a single chip, a computer, or other electronic devices capable of storing and running programs. The steps include:

step S101: receiving a test instruction sent by an upper computer, and sending an update instruction to a 13.56MHz card reader according to the test instruction, so that the 13.56MHz card reader writes first simulation entry information into a first structure file used for storing entry information in a CPC card and writes first simulation path information into a second structure file used for storing path information.

Step S102: and sending a card reading instruction to the 13.56MHz card reader, receiving second simulation entry information read from the first structure file in the CPC card and returned by the 13.56MHz card reader, reading second simulation path information from the second structure file, and recording.

Step S103: and sending a closing instruction to the 13.56MHz card reader.

Step S104: and sending a pre-reading instruction to the 5.8GHz antenna, receiving and recording third simulation inlet information read from the first structure file in the CPC card and third simulation path information read from the second structure file returned by the 5.8GHz antenna.

Step S105: and sending a closing instruction to the 5.8GHz antenna.

Step S106: and comparing the second simulation entrance information with the third simulation entrance information and the second simulation path information with the third simulation path information, and generating a pre-reading test result.

In step S101, the upper computer may adopt a single chip, a computer, or other electronic devices capable of storing and running programs, and the upper computer may interact with the tester, receive the control of the tester, and perform start-stop control on the test. And the upper computer is loaded with a corresponding control program to generate a start-stop instruction. And after receiving the detection instruction of the upper computer, the main control module starts to carry out test operation and sends an updating instruction to the 13.56MHz card reader. The information writing operation at the entrance of the expressway is simulated by a 13.56MHz card reader. In this embodiment, the card reader with 13.56MHz frequency is used to refer to the current CPC card writing method to restore the real usage scenario. Specifically, a CPC card to be tested is placed on the integrated detection equipment, a worker controls the upper computer to send a test instruction to the main control module, and the main control module generates and sends an update instruction to the 13.56MHz card reader to instruct the CPC card to write information into the CPC card. Further, in order to ensure that normal communication between devices can be realized, the CPC card stores information by adopting a specific file structure, and a specific storage path is appointed to store information of a specified type. Therefore, the entrance lane information and the route information can be written with reference to the stored route of the information in the actual operation process to completely simulate the real use scene. A memory path dedicated to testing may also be provided for detecting a read-ahead function.

The updated entrance lane information and the updated route information may be contents generated according to an expression rule in an actual operation process, or may be random codes in a corresponding format as simulated entrance lane information and simulated route information. Illustratively, 17 th to 18 th bytes of the A folder are used for storing entrance lane information, and in the actual operation process, 11008433 represents the entrance of the southwest expressway at the Beijing Bihua intersection, so that 11008433 can be directly written into the 17 th to 18 th bytes of the A folder of the CPC card for testing. In other embodiments, the 8-bit data written into bytes 17-18 of the A folder may be randomly generated for testing.

In some embodiments, referring to a file structure of an OBE-SAM, the first structure file is a DF01-EF01 file in a CPC card file structure, the storage path is a first ordinal byte to a second ordinal byte of the DF01-EF01 file, and may specifically be 15-25 bytes of the DF01-EF01 file, where 15-16 bytes are used for storing an entrance road network number, 17-18 bytes are used for storing an entrance toll station number, 19 bytes are used for storing an entrance toll lane number, 20-23 bytes are used for storing an entrance time, 24 bytes are used for recording a byte for 5.8GHz antenna read-write control, and 25 bytes are used for recording an entrance lane type. In other embodiments, 1-14 bytes of the DF01-EF01 file are also read, wherein the 1 st byte records the vehicle type, the 2-13 bytes record the license plate number, and the 14 th byte records the license plate color.

The second structure file is a DF01-EF02 file in the CPC card structure file, and the specific storage path is 1 to third ordinal bytes of the DF01-EF02 file, and may be 1 to 101 bytes of the DF01-EF02 file, where the 1 st byte records the number of transit provinces, the 2 nd byte records the number of provinces gantries, the 3 rd to 5 th bytes record the cumulative amount of the provinces, the 6 th to 8 th bytes record the mileage charged by the provinces, the 9 th to 15 th bytes record the information of the province entry ETC gantries, the 16 th to 28 th records the information of the written latest gantries, the 28 th byte records the number of the written gantries, and the 29 th to 101 th bytes are used for sequentially writing the latest gantry codes.

The file storage in the CPC card has a specific structure, and a specific storage path is used to store specific content according to a corresponding communication protocol, and therefore, in this embodiment, the first structure file and the second structure file are associated with a path in which entry lane information and path information are stored in an actual usage scene. The DF01-EF01 in the CPC file structure is used for recording contents such as entrance lane information, and the two information can be changed in an actual application scenario. DF01-EF02 is used to record path information, and may be segmented by specific fields to mark multiple portals or provincial lanes traversed.

In step S102, the embodiment is a test of the read-ahead function of the CPC card, and mainly compares the information stored in the CPC card with the read-ahead generated information. In the writing process of step S101, data loss or confusion may occur, and therefore, before detecting the read-ahead function, the content stored in the card needs to be re-confirmed for comparison with the information obtained by the subsequent read-ahead. Specifically, the second analog entry information and the second analog path information related to the entry and the travel path are read by the 13.56MHz card reader according to the written path in step S101. The second simulation entry information and the second simulation path information may be recorded in the integrated test apparatus.

In step S103, in order to simulate the state of the vehicle leaving the field and leaving the signal coverage range of the read-write device in the real usage environment, the main control module sends a closing instruction to the 13.56MHz card reader to block the continuous interference of the read-write signal, and simulate the state of the CPC card during the driving process of the vehicle.

In step S104, the main control module sends a pre-read instruction to the 5.8GHz antenna, pre-reads the information written in the CPC card, and extracts information for transaction. The extracted path is consistent with the storage path, namely the structure file consistency fields of the corresponding information are written and read in, and third simulation entrance information and third simulation path information related to the entrance, the vehicle identity and the driving path are obtained.

In step S105, the main control module sends a close command to the 5.8GHz antenna to simulate an action of stopping pre-reading.

In step S106, the consistency between the pre-read information and the information in the CPC card is determined by comparing the second simulation entry information and the third simulation entry information, and the second simulation path information and the third simulation path information, so as to verify whether the pre-read function of the CPC card is normal, and generate a corresponding pre-read test result based on the result.

In some embodiments, after sending the card reading instruction to the 13.56MHz card reader in step S102, the method further includes:

and receiving and recording the first issuer information, the first version information, the first ID information and the first validity period information which are read and generated from the third structure file in the CPC card and returned by the 13.56MHz card reader.

Correspondingly, after the step S105, sending the pre-read command to the 5.8GHz antenna, the method further includes:

and receiving and recording second issuer information, second version information, second ID information and second validity information which are read and generated from a third structure file in the CPC card and returned by the 5.8GHz antenna.

And comparing the first issuer information with the second issuer information, the first version information with the second version information, the first ID information with the second ID information, and the first validity information with the second validity information, and generating a pre-reading test result.

In this embodiment, in the process of highway toll transaction, in addition to reading and collecting information related to an entrance lane, a vehicle identity and a driving path, pre-reading equipment information of the CPC card itself is required to confirm card tag validity. For example, some CPC cards may have an outstanding itinerary due to non-regular use, and for such cards, the ID information may be verified to determine validity. And partial CPC cards can not be traded due to exceeding the validity period, and can be judged by verifying the validity period information. Therefore, the embodiment simultaneously verifies and tests the pre-reading effect on the information of the issuer, the version, the card ID and the validity period in the pre-reading test so as to completely simulate the real use scene. In some embodiments, referring to a file structure of an on-highway electronic toll collection (OBE-SAM), a third structure file is an MF-EF01 file in a file structure of a CPC card, and card label information recorded by an MF-EF01 file cannot be rewritten in a use process of the CPC card, wherein 1-8 bytes are used for recording an identifier of a publisher of the CPC card, 9-16 bytes are used for recording an ID of the CPC card, a 17 th byte is used for recording a version number, 18-21 bytes are used for recording a contract signing date, and 22-25 bytes are used for recording a contract expiration date.

In some embodiments, before sending the read-ahead instruction to the 5.8GHz antenna in step S105, S1051 to S1052 are further included:

s1051: and sending a security verification instruction to the 5.8GHz antenna, and receiving security password information read from the CPC card returned by the 5.8GHz antenna.

S1052: sending the security password information to a PSAM (terminal security control module) module for verification, and if the verification is passed, sending a pre-reading instruction to a 5.8GHz antenna; and stopping the test if the verification is not passed.

In order to guarantee the security of read-write transaction, the CPC card is verified through the PSAM security module. In this embodiment, the security password is verified, and other security access methods or permission granting methods may also be used. The pre-reading of the CPC card involves a large amount of key information related to transactions, and the security verification is an important ring in a pre-reading mechanism, so that the security of the pre-reading of the CPC card is judged by simulating the verification step of the PSAM security module in the embodiment. Further, the security is the basis of a pre-reading mechanism, so that once the security password information is not verified, the security is defective, and the CPC card pre-reading function has a security fault, subsequent testing is stopped.

In some embodiments, in step S106, the pre-read test result is generated, including S1061 to S1062:

s1061: and if the second simulation entrance information is consistent with the third simulation entrance information and the second simulation path information is consistent with the third simulation path information, judging that the test is passed.

S1062: and if the second simulation entrance information is inconsistent with the third simulation entrance information or the second simulation path information is inconsistent with the third simulation path information, generating an error log.

The test of the pre-reading mechanism is actually a test of the pre-reading accuracy, and the standard set in this embodiment is that the test can be determined to pass only when the information stored in the CPC card is completely consistent with the information obtained by pre-reading. If only one of the three corresponding sets of information is inconsistent, the test fails, and an error log is generated. The content of the error log record includes test time, ID information of the CPC card, error content, possible reasons for error occurrence, and corresponding handling method.

In some embodiments, before generating the pre-read test result in step S106, the method further includes:

and carrying out a plurality of tests and summarizing to form a pre-reading test result.

Due to communication, the data writing error of the equipment can be caused, and accidental faults can be caused. Therefore, in this embodiment, the results of the multiple tests are integrated, and the pre-read test results are generated in a summary manner. In some embodiments, the error reporting is performed only when the same error occurs continuously or intermittently over a set ratio.

and testing and summarizing for many times, and adding the identity information of the CPC card into a grey list when the same error occurrence frequency is smaller than a set proportion. The CPC card in the grey list can be used for operation, but the failure rate of the CPC card should be monitored in an important mode.

In some embodiments, in step S106, after generating the pre-read test result, the method further includes:

and sending the pre-reading test result to a display module for displaying.

In the embodiment, the pre-read test result is displayed through a display, and is sufficiently applied to some application scenarios in which the result needs to be fed back in time. For example, when a CPC card is issued at the entrance of a highway, each card may be tested in real time to check its validity. The display module can be used for displaying to a tester and can also be used for displaying to a user at the entrance of the lane. The display module can adopt the LED screen, can show CPC card function normal when the test passes, can show CPC card when the test does not pass and read unusually.

In some embodiments, the method further comprises:

and sending the pre-reading test result to an upper computer for displaying and recording.
