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.

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, in an actual operation environment, a large amount of interference signals are filled, which may cause CPC operation abnormality, for example, when an ETC device near a lane reads and writes a vehicle-mounted tag by using 5.8GHz, it may cause CPC card writing abnormality or interruption of a pre-reading process; the square wave signal and the 5G signal can cause the CPC card to wake up abnormally, and cause the CPC card to write abnormally or interrupt the pre-reading process, so that data is disordered.
Therefore, the invention provides a method and a device for testing a pre-reading mechanism of a CPC card under antenna interference, which are used for simulating various signal interference scenes and simulating the real transaction process of the CPC card so as to test whether the read-write function and the pre-reading function of the CPC card are effective under the interference condition.
In order to meet the test requirements, as shown in fig. 2 and fig. 3, the method of the present invention adopts an integrated test device 120 including a main control module 121, an interference antenna 122, a 13.56MHz card reader 123, and a 5.8GHz antenna 124 to perform detection, and the integrated test device 120 is connected to an upper computer 110. The interference antenna 122 is used for transmitting square wave signals, 5G signals and/or 5.8GHz signals for interference. Wherein, the 13.56MHz card reader 123 and the 5.8GHz antenna 124 are controlled by the main control module 121 to perform read-write operation simulation on the CPC card 130; the interference antenna 122 is controlled by the main control module 121, and generates an interference signal based on the 3 signal transmitters, so as to simulate various interference situations, for example, a square wave signal used when the CPC card 130 is awakened by the portal antenna or the lane transaction antenna, a 5G signal of a specific frequency band spectrum generated when the 5G device is in operation, and a 5.8GHz signal used in a communication process of the portal antenna and the lane transaction antenna.
Specifically, the method for testing the CPC card pre-reading mechanism under the antenna interference comprises the following steps of S101-S107:
it should be noted that, in this embodiment, the descriptions of steps S101 to S107 do 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. As shown in fig. 1, the steps include:
step S101: and receiving a test instruction sent by the upper computer, and sending an interference instruction to the interference antenna according to the test instruction so that the interference antenna sends out a square wave signal, a 5G signal and/or a 5.8GHz signal as an interference signal.
Step S102: and sending an updating instruction to the 13.56MHz card reader so as to update and write the simulated entrance lane information and the simulated path information into the CPC card to be tested according to the first set of set paths.
Step S103: and sending a reading instruction to the 13.56MHz card reader so as to respectively read the simulated entrance lane information and the simulated path information recorded in the CPC card to be tested according to the first set of set paths, wherein the simulated entrance lane information and the simulated path information are recorded as first entrance lane information and first path information.
Step S104: and sending a closing instruction to the 13.56MHz card reader.
Step S105: and sending a pre-reading instruction to the 5.8GHz antenna so as to respectively read the second entrance lane information and the second path information recorded in the CPC card to be tested according to the first set of set paths.
Step S106: and sending a closing instruction to the 5.8GHz antenna and the interference antenna.
Step S107: and comparing the first entrance lane information with the second entrance lane information and the first path information with the second path information aiming at the corresponding interference signals to generate a test result about the pre-reading function of the CPC card to be tested.
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 to receive the control of the tester and perform start and 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. Specifically, an interference instruction is sent to the interference antenna, and the specified interference type may be marked in the interference instruction, or each interference type may be tested according to a set sequence. The signal that has the interference to the CPC card transaction process that awaits measuring mainly includes: the square wave signals sent by the portal antenna or the lane transaction antenna are used for waking up other CPC cards, 5.8GHz signals for reading and writing other CPC cards, and 5G signals generated by 5G equipment in a communication environment. Various interference signals can occur independently or simultaneously so as to simulate the actual application scene.
In some embodiments, the square wave signal generated by the interference antenna is used for simulating an update writing instruction of the lane antenna and/or the portal antenna to other CPC cards so as to test whether the read-ahead of the CPC card to be tested is influenced.
In some embodiments, the 5.8GHz signal generated by the interference antenna is used to simulate the read-ahead command of the lane antenna for other CPC cards, so as to test whether the read-ahead of the CPC card to be tested is affected.
In step S102, a 13.56MHz card reader is used to simulate an information writing process in an actual scene, and information related to the entrance, the vehicle identity, and the driving path is written into the CPC card to be tested. Specifically, because the CPC card to be tested has a specific file structure and specific information has a special storage path, it is necessary to store and store the simulation entrance lane information and the simulation path information according to a first set of set paths in the actual application process. Illustratively, a DF-EF01 file of a file structure is used for storing entrance lane information and the like, specifically, the 1 st byte in the DF-EF01 file is used for storing vehicle type information, the 2 nd to 13 th bytes are used for storing license plate number information including Chinese characters, letters and numbers, the 15 th to 16 th bytes are used for storing entrance toll road number, the 17 th to 18 th bytes are used for storing entrance lane number, and the 19 th byte is used for storing entrance toll lane number.
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 station number of the southwest expressway at the Beijing Bihuan junction, so that 11008433 can be directly written into the 17 th to 18 th bytes of the A folder of the CPC card to be tested 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 step S103, the embodiment is a test of the pre-reading function of the CPC card to be tested under the interference condition, and mainly compares the information stored in the CPC card to be tested with the pre-reading generated information. In the writing process of step S102, 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 first entrance information and the first path information related to the entrance, the vehicle identity, and the travel path are read by the 13.56MHz card reader according to the first set of set paths in step S102. The first entry information and the first path information may be recorded in the integrated test apparatus.
In step S104, in order to simulate the state that the vehicle leaves the field and is out of the signal coverage of the read-write device in the real use environment, the main control module sends a closing instruction to the 13.56MHz card reader, and simulates the state of the CPC card to be tested in the vehicle driving process.
In step S105, according to the work flow of the exit lane transaction antenna in the actual operation process, the CPC card is pre-read by using the 5.8GHz antenna to obtain information required for the transaction, and the information is recorded as second entrance lane information and second path information for comparison.
In step S106, the main control module sends a close command to the 5.8GHz antenna to simulate the action of stopping pre-reading. Meanwhile, the main control module sends a closing instruction to the interference antenna to stop interference.
In step S107, whether the information generated by pre-reading the CPC card to be tested is consistent with the information stored in the CPC card under the specific interference signal is analyzed, and if all the information is consistent, it may be determined that the CPC card to be tested is not affected by the interference signal. Otherwise, if the information is inconsistent, it can be determined that the pre-reading is abnormal due to the influence of the interference signal. Furthermore, by analyzing the difference between the transaction information read for the first time and the transaction information generated by pre-reading and combining with a specific interference signal, the influence of the specific type of interference signal on the information pre-reading in the CPC card pre-reading process can be analyzed.
In other embodiments, it is also possible to start and stop the interference antenna at intervals during the pre-reading process, i.e. in step S105, to analyze whether the interference signal of a specific kind will block and interrupt the pre-reading. Illustratively, when the path information is pre-read, the interference antenna is started to generate a 5.8GHz signal, the content of the generated second path information is empty, the interference antenna is closed when the path information is pre-read, and the content of the generated second path information is consistent with the first path information, so that it can be judged that the pre-reading of the CPC card to be tested is interrupted by the 5.8GHz signal. Similarly, the method can be used for judging whether the square wave signal for waking up other CPC cards can cause the pre-reading interruption of the CPC card to be detected or not, and judging whether the 5G signal of the 5G equipment can cause the pre-reading interruption of the CPC card to be detected or not.
In some embodiments, generating test results for the CPC card read-ahead function includes:
and if the second entry information is consistent with the first entry information and the second path information is consistent with the first path information, judging that the test is passed.
And if the second entry information is inconsistent with the first entry information or the second path information is inconsistent with the first path information, judging that the test is not passed, and 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, under the condition of signal interference, only when the information stored in the CPC card is completely consistent with the information obtained by pre-reading, it can be determined that the pre-reading function of the CPC card is not affected by the interference signal, and the test is approved. 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 step S105, i.e. before sending the read-ahead command to the 5.8GHz antenna, the method further includes S1051-S1052:
s1051: sending a security verification instruction to a 5.8GHz antenna, and receiving security password information read from the CPC card to be tested, which is returned by the 5.8GHz antenna;
s1052: the safety password information is sent to a PSAM module for verification, and if the safety password information passes the verification, a pre-reading instruction is sent to a 5.8GHz antenna; and if the verification fails, stopping the test, and generating a fault log by combining the interference information.
In order to guarantee the security of read-write transaction, the CPC card to be tested 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 to be tested relates to 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 pre-reading security of the CPC card to be tested 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 to be tested has a security fault, the subsequent test is stopped. In other embodiments, the interference signals are respectively tested for their influence on the security verification by starting and stopping the interference antennas, and the fault log is used to record the security test result of the CPC card under a specific interference condition.
In some embodiments, after step S103, that is, after sending the reading instruction to the 13.56MHz card reader, the method further includes:
receiving first issuer information, first version information, first ID information and first validity period information which are returned by a 13.56MHz card reader and read and generated from a second set of set paths in the CPC card to be tested;
correspondingly, after step S105, that is, after sending the read-ahead command to the 5.8GHz antenna, the method further includes:
receiving second issuer information, second version information, second ID information and second validity period information which are returned by a 5.8GHz antenna and are respectively read from a second set of set paths in the CPC card to be tested and generated;
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 aiming at the corresponding interference signals, 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 to be tested needs to be performed to confirm card-tag validity. For example, part of CPC cards to be tested may have an unpaid journey because the CPC cards are not used conventionally, and the cards can be judged to be valid by verifying the ID information. And partial CPC cards can not be transacted 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 under the interference condition 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, before generating the test result regarding the CPC card read-ahead function in step S107, the method further includes:
