Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention are further described in detail below with reference to the 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.

The ETC road side unit and the vehicle-mounted unit realize charging transaction in a wireless Communication mode, wherein a Communication protocol can adopt a Dedicated Short Range Communication (DSRC) protocol. The treatment process comprises the following steps: an ETC Vehicle-mounted Unit (Road Side Unit, RSU) periodically transmits downlink Beacon Service Table (BST) signals, and when a Vehicle provided with the On-Board Unit (OBU) drives into an ETC charging area, the Vehicle receives the BST signals and returns the VST signals. The VST signal contains the Media Access Control (MAC) address of the on-board unit, which is its primary identifier for communication with the RSU antenna, a serial number, and other information. After receiving the uplink DSRC signal data frame, the RSU antenna distinguishes different vehicle-mounted units by the MAC address of the RSU antenna; the downlink signal data frames sent to different vehicle-mounted units by the RSU antenna all use the MAC address of the target vehicle-mounted unit as the special link identification of the downlink frame. The vehicle-mounted unit only receives the downlink data frame with the exclusive link identification being the same as the MAC address of the vehicle-mounted unit. After receiving the VST signal, the RSU antenna firstly carries out safety authentication with the vehicle-mounted unit, and after the vehicle is confirmed to be a legal vehicle after the authentication is passed, ETC charging transaction is carried out with the vehicle-mounted unit. After ETC transaction communication is finished, the RSU antenna transmits an end instruction, then continues to transmit periodic downlink BST signals, and waits for the driving of subsequent vehicles.

one of the basic functions of the on-board unit is to operate the user card, and the operations of reading the card information of the user card, writing the information in the ETC system into the user card, charging the user card and the like can be completed through the card reading and writing module of the on-board unit. According to long-term operation experience of the ETC system, the stability of the work of the read-write card module of the vehicle-mounted unit directly influences the normal operation of the system and the non-stop traffic of a large number of users. Due to the reasons of the production manufacturing process, the device selection, the software design and the like of the vehicle-mounted unit, faults such as unstable operation of the read-write card and even failure of the read-write card occur with a certain probability after the vehicle-mounted unit is plugged and unplugged for many times, and therefore how to detect the stability and the reliability of the function of the read-write card after the vehicle-mounted unit is plugged and unplugged is a problem which needs to be solved urgently in an ETC system.

In order to solve the above problems, the present invention provides an automatic card plugging and unplugging test method for an ETC user card, as shown in fig. 1, the automatic card plugging and unplugging test method for an ETC user card according to some embodiments may include the following steps S110 to S160.

The method can be realized by utilizing a controller, and the controller can be equipment such as an industrial personal computer, a server, a personal computer, a tablet personal computer, a mobile phone or a single chip microcomputer. The person skilled in the art knows that the order of execution of the steps of the method can be adjusted where possible, so that the order of execution of the steps is not limited by the present invention unless otherwise specified.

step S110: and outputting a card plugging control signal to the card plugging equipment so that the user card is automatically inserted into the vehicle-mounted unit and exits from the vehicle-mounted unit after the set retention time of the inserted card is kept.

The card plugging and unplugging equipment can comprise a mechanical arm, a card inserting groove, a vehicle-mounted unit fixing piece and the like. The plug card control signal can be specifically transmitted to a mechanical arm in the plug card device, and the mechanical arm can push all or part of the user card outside the card slot into the card slot according to the plug card control signal. When the user card enters the card inserting operation, the user card can be electrically connected with a vehicle-mounted unit (electronic tag) fixed by a vehicle-mounted unit fixing part, which is equivalent to that a user inserts the user card into the vehicle-mounted electronic tag. Wherein, the user card can be a stored value card, a billing card and the like, and can be charged; the vehicle-mounted electronic tag or the vehicle-mounted unit can perform information interaction with a road side unit of the ETC system.

the plug-in card control signal may carry plug-in card control parameters, wherein the plug-in card control parameters may include one or more of a card insertion speed, a card insertion force, and a retention time after card insertion. The retention time after the card is inserted can refer to the time for keeping the card-inserting state after the user card is inserted into the card-inserting and extracting device and the card is inserted in place, and can be determined by referring to the time spent in the execution of one or more subsequent steps so as to ensure that the vehicle-mounted unit and the road side unit complete the transaction. In some embodiments, the post-insertion dwell time may refer to the time from the time of insertion of the card to the time of turning off the antenna; the card can be pulled out manually or automatically after the antenna is closed. After the retention time after the card insertion is continuously finished, the user card can be ejected from the card inserting and extracting device (the ejection mechanism or the mechanical arm can be used for assisting the ejection of the user card). Different card inserting habits of users can be simulated by using different card inserting speeds and/or card inserting forces, so that the test result can be more accurate. In other embodiments, the card plugging control signal may not carry card plugging control parameters, and the mechanical arm of the card plugging device receives the card plugging control signal and inserts the card according to the inherent force or speed.

The card plugging device, particularly the control circuit of the mechanical arm thereof, and the controller of the method can be in communication connection in various modes, such as a serial port, a control interface, a bus and the like, so as to transmit a card plugging control signal to the card plugging device.

optionally, before the step S110, the method shown in fig. 1 may further include the steps of: s170, receiving the input card plugging control parameters. The plug-in card control parameters comprise one or more of card insertion speed, card insertion force and retention time after card insertion, and the plug-in card control signals comprise the plug-in card control parameters. The plug card control parameters can be manually input to the execution device of the method through various input devices (such as a keyboard, a mouse, a touch screen and the like). After receiving the card plugging control parameter, the execution device of the method may add the card plugging control parameter to the card plugging control signal for outputting together if the card plugging control signal needs to be output, where the outputting together mainly refers to outputting simultaneously and is not limited to transmitting in the same transmission channel or communication line. The step S170 may be a part of the preparation work, and after the execution device of the method receives the card plugging control parameter, the execution device may execute an action of starting the test, and then start to execute the step S110.

the same or different plug-in card control parameters can be adopted in different plug-in card testing processes; or, the input card plugging control parameters can be received only at the beginning, but the card plugging control parameters can be adjusted according to the set rule when the next test is carried out, so that the method can automatically simulate various user card inserting behaviors.

Optionally, before the step S110, the method shown in fig. 1 may further include the steps of: and S180, receiving and storing the input card information, and inputting the input card information into the user card. The card information may include one or more types of information involved in transactions or interactions between the roadside unit and the on-board unit, such as a 0015 file, a 0019 file, a 0002 file (a file in technical requirements for toll road networking electronic toll collection (No. 13 bulletin 2011) according to ETC-related industry specifications), and the like. The 0015 file is a card issuing basic data file and is information written in the process of secondary issuing of a user card, and the rewriting can be omitted in the process of transaction between the road side unit and the vehicle-mounted unit; 0019 the file is a file special for consumption, and every transaction can be modified according to the time, site and other information of the transaction; the 0002 file is an electronic wallet file, the balance of the wallet of the user card is recorded, and after the fee deduction of each transaction is successful, the 0002 file can reduce the corresponding fee deduction amount. The card information generally needs to conform to the format of the corresponding file, and the specific content can be randomly written.

The card information can be copied from other storage equipment to the execution equipment of the method manually, and the execution equipment of the method can store the obtained card information into one copy and input the card information into the user card. The user card can be connected with the execution device of the method through the card plugging device or other devices (such as a card reader) in a communication mode so as to enter card information into the user card. The step S180 may be a part of the preparation work, and after the execution device of the method receives and stores the input card information, and inputs the card information into the user card, an action of starting the test may be performed, and then the step S110 is performed.

Step S120: and receiving a card-inserting in-place signal of the user card inserted into the vehicle-mounted unit.

The card plugging and unplugging device can comprise a card insertion in-place detection device, the card insertion in-place detection device can be an infrared detection element, a pressure detection element and the like, and the setting position can be determined according to the position where the user card can be electrically connected with the vehicle-mounted unit. When the user card is inserted in place, the in-place card insertion detection device of the card plugging and unplugging device can detect that the user card is inserted in place and send an in-place card insertion signal to the execution device of the method.

In other embodiments, the card plugging and unplugging device may further include a card complete unplugging detection device, and similarly, the card complete unplugging detection device may be an infrared detection device, a pressure detection device, or the like, may determine a setting position according to a position of a slot of the card insertion device, and may be different from the card in-place detection device in the setting position. In other words, in these embodiments, the method shown in fig. 1 may further include the steps of: and receiving a card complete pulling-out signal that the user card pulls out the vehicle-mounted unit. The card complete plug-out signal may be executed after the transaction between the on-board unit and the roadside unit is completed, for example, after the subsequent step S130, which may indicate that one card plugging-out operation is completed, and may further facilitate the next card plugging-out test.

illustratively, the card-in-place detection device and/or the card complete-extraction detection device may be communicatively connected with the execution device of the method in various ways, for example, through an I/O interface, in which case, if the card-in-place detection device detects that the user card is in place, 1 may be output, otherwise 0 may be output to the execution device of the method; if the card complete extraction detection device detects that the user card is completely extracted, 1 can be output, otherwise, 0 can be output to the execution equipment of the method. Under the condition that the card plugging and unplugging device is provided with a card plugging in-place detection device and a card completely unplugging detection device, the detection result of the card plugging position can be represented by a two-digit binary number, for example, 00 represents that the card plugging is not in place and the card unplugging is not in place, namely, the card plugging and unplugging device can represent that the card is in the process of plugging or unplugging or is in the state that the card is in virtual connection with a vehicle-mounted unit; the situation that the card is inserted in place but not pulled out in place is represented by 01, namely the situation that the card is inserted in place can be represented; the card is pulled out to the right position and inserted to the right position by 10, namely, the state of pulling out the card to the right position can be shown.

step S130: and outputting a transaction control signal to a road side unit according to the card insertion in-place signal so that the road side unit reads the card information from the user card and writes the transaction information into the user card according to the read card information to complete the transaction.

for example, the read in-card information may include one or more of a card issuance base data file (0015 file), a composite consumption-specific file (0019 file), and a pre-transaction electronic wallet file (0002 file); the written transaction information may include a modified composite consumption specific file (0019 file). By reading the card issuance basic data file in the user card, basic information of the user card, such as a MAC address of the user card, a serial number, and the like, can be obtained, where the MAC address can be used to find the user card, and the serial number can facilitate finding the user card in the ETC system. Of course, the method is only used for testing, and the card issuing basic data file may not necessarily play a practical role, and may only be used for checking whether the reading result is correct. The information related to the previous transaction of the user card, such as the previous transaction time, the site and the like, can be known through the composite consumption special file.

When information needs to be written in, transaction information is written in the user card according to the read information in the card so as to complete a transaction, specifically, for example, the composite consumption special file can be modified according to the current transaction time and site, and the modified composite consumption special file is written in the user card, meanwhile, the road side unit can transmit the transaction amount obtained according to the information recorded by the ETC system or transmitted to the road side unit to the user card, and the electronic wallet file on the user card is controlled to subtract the amount, so that the transaction amount is changed into the electronic wallet file after the transaction. The sum can be transmitted to the user card through the composite consumption special file, and then the electronic wallet file is modified by the user card, or the electronic wallet file is directly modified, and then the modified electronic wallet file is transmitted to the user card.

The purpose of writing the transaction information is to complete the transaction, if the transaction is actually completed, the transaction is successful, if the transaction cannot be completed due to insufficient balance or failure in reading and writing the card, the transaction fails, after the transaction operation is performed, the vehicle-mounted unit can feed back the result of the transaction to the road side unit, and then the execution device of the method can acquire the transaction result through a communication connection line (for example, a serial port, a network port, a bus connection and the like) between the execution device and the road side unit.

optionally, before the step S130, the method shown in fig. 1 may further include the steps of: and S190, outputting an antenna carrier wave opening control signal to the road side unit. In general, the antenna of the road side unit may continuously and periodically transmit the downlink BST signal, and wait for the on-board unit to receive the downlink BST signal. However, when the plug-in and pull-out card test is performed, it is desirable that the BST signal is received when the BST signal needs to be received so that information interaction between the RSU antenna and the vehicle-mounted unit can be performed. Therefore, an antenna carrier control switch may be disposed in the road side unit, and when a transaction needs to be performed (for example, step S130 needs to be performed), the RSU antenna is turned on in advance to transmit a carrier signal, so as to perform a transaction with the vehicle-mounted unit. Therefore, interference caused by unnecessary signals transmitted by the RSU antenna to the plug-in card test process can be prevented.

Optionally, after the step S130, the method shown in fig. 1 may further include the steps of: s1200, outputting an antenna carrier wave closing control signal to the road side unit. After the transaction is completed, when the information interaction between the vehicle-mounted unit and the RSU antenna is not required in the subsequent processing process of the card plugging and unplugging test, the antenna carrier is closed, and unnecessary signals are prevented from being transmitted by the antenna. After the antenna carrier is closed, the RSU antenna may still be in a powered-on state, and only the BST signal is not transmitted, so that when the antenna is required to continuously transmit the BST signal, the antenna may be quickly controlled to transmit the carrier signal for the next transaction.

Step S140: and acquiring a transaction result and the read in-card information from the road side unit.

After the road side unit detects the vehicle-mounted unit, the information in the card is read from the user card inserted into the vehicle-mounted unit, at this moment, the fee deduction transaction is not carried out, and at this moment, the road side unit can transmit the read information in the card to the execution equipment of the method. After the road side unit knows the charge amount to be deducted of the user card according to the read information in the card, the information needing transaction can be written into the user card through the vehicle-mounted unit, so that the charge is deducted, the charge deduction transaction is possible to succeed or fail, the transaction result can be returned to the road side unit through the vehicle-mounted unit, and at the moment, the road side unit can transmit the transaction result to the execution equipment of the method. Thus, the transaction result and the read in-card information can be acquired from the roadside unit. Of course, in other embodiments, it may be possible to obtain the required information from other means, for example, obtaining the transaction results and/or the read in-card information from the on-board unit.

step S150: and judging whether the reading of the information in the card is normal or not by comparing the read information in the card with the card information which is pre-input to the user card.

under the condition that the card information of the user card before the card plugging test is not changed relative to the card information pre-entered into the user card, whether the card information reading is normal or not can be judged by comparing the read card information with the card information pre-entered into the user card, specifically, if the card information is consistent, the card information reading is normal, otherwise, the card information reading is abnormal. Under the condition that the card information of the user card before the card plugging and unplugging test changes relative to the card information which is pre-input to the user card, the information after the test change of the previous time can be obtained according to the change information (such as deduction amount) and the information read before the previous time of change, and then whether the read information is normal or not is judged by comparing the consistency of the information after the previous time of change and the information in the card read at this time.

for example, the read in-card information may include a card issuance base data file, a composite consumption dedicated file, and an electronic wallet file, and the card information previously entered into the user card may include a card issuance base data file, a composite consumption dedicated file, and an electronic wallet file. In this case, when the card insertion and extraction test is performed for the first time, it is possible to compare whether the read card issuance basic data file is identical to the card issuance basic data file that has been previously entered, whether the read composite consumption dedicated file is identical to the composite consumption dedicated file that has been previously entered, and whether the read electronic wallet file is identical to the electronic wallet file that has been previously entered. If the card is not plugged and unplugged for the first time, the pre-recorded composite consumption special file may be updated to the composite consumption special file which is modified and written in the latest card plugging and unplugging test, and under the condition, whether the composite consumption special file read in the test is consistent with the composite consumption special file modified for the previous time or not can be compared; of course, since the card issuance base data file is not generally changed, the consistency between the read card issuance base data file and the card issuance base data file previously entered into the user card can be compared regardless of the card insertion/removal test.

Step S160: and judging whether the card plugging of the vehicle-mounted unit is successful according to the judgment result of whether the card information reading is normal and the acquired transaction result.

For example, by comparing the read card information with the card information previously entered into the user card, it is determined that the card information reading is normal and the transaction result is also normal, and it may be considered that the card insertion and removal of the vehicle-mounted unit is successful this time, that is, the vehicle-mounted unit is stable in reading and writing. If the reading of the information in the card fails or the transaction fails, the card plugging and unplugging of the vehicle-mounted unit can be considered to be failed.

in the embodiments, a card plugging control signal is output to the card plugging device, so that the user card is automatically inserted into the vehicle-mounted unit, a card insertion in-place signal of the user card inserted into the vehicle-mounted unit is received, a transaction control signal is output to the roadside unit according to the card insertion in-place signal, the roadside unit reads card information from the user card, transaction information is written into the user card according to the read card information to complete a transaction, then the card plugging device extracts the user card, a transaction result and the read card information are obtained from the roadside unit, whether card information reading is normal or not is judged by comparing the read card information with card information pre-entered into the user card, and whether card plugging of the vehicle-mounted unit is successful or not is judged according to a judgment result whether card information reading is normal or not and the obtained transaction result, so that the influence of the plugging card on the card reading and writing card mode stability of the vehicle-mounted unit can.

fig. 2 is a schematic flow chart of an automatic plug-in and pull-out card testing method for an ETC user card according to another embodiment of the invention. Referring to fig. 2, in other embodiments, the automatic plug-in and plug-out card testing method for the ETC user card shown in fig. 1 may further include the following steps S210 to S260. After the card plugging and unplugging test of the on-board unit is completed once through the steps S110 to S160, the next card plugging and unplugging test of the on-board unit can be performed through the steps S210 to S260.

step S210: and after the user card exits the vehicle-mounted unit, outputting a card plugging control signal to the card plugging device again so as to ensure that the user card is automatically plugged into the vehicle-mounted unit again and the retention time after the card is plugged is maintained again.

For example, in step S110, the card plugging device inserts the user card into the vehicle-mounted unit according to the card plugging control signal, and allows the user card to maintain the card plugging state for a certain time, during which the transaction process between the road side unit and the vehicle-mounted unit can be completed, and the user card can be withdrawn from the vehicle-mounted unit after the card reading and writing operation is performed. Therefore, the ejection of the user card from the in-vehicle unit in step S210 may refer to the ejection of the user card from the in-vehicle unit in this example. The specific implementation of step S210 may be similar to step S110 described above.

The plug-in card control signal can carry plug-in card control parameters, which can include card-inserting speed, card-inserting force, retention time after card-inserting, and the like. In addition, the card plugging control parameter may include a card plugging frequency, and according to the set card plugging frequency, the steps S210 to S260 may be performed in a loop until the requirement of the test frequency is met. The step S210 may be the same or similar in the process of testing the pluggable card for different times.

step S220: re-receiving a card-inserting-in-place signal of the user card inserted into the vehicle-mounted unit;

According to the obtained card plugging control signal, the card plugging device can enable the user card to be plugged into the vehicle-mounted unit again. When the card is inserted in place, a corresponding card in-place signal can be obtained. The specific implementation of this step is similar to step S120 described above.

Step S230: and outputting a transaction control signal to the road side unit again according to the re-received card insertion in-place signal so that the road side unit reads the card information from the user card again and writes the transaction information into the user card again according to the read card information to complete the transaction again.

The detailed implementation of this step may be similar to step S130 described above. The specific content may be different for the read in-card information when the previous test is modified. For example, the card issuance basic data file read this time may be identical to the card issuance basic data file read in the previous test; the contents of the composite consumption special file read at this time and the composite consumption special file read before the previous transaction can be different, because the time, the site and the like of the previous transaction can be modified in the composite consumption special file read at this time; the contents of the electronic wallet file read this time and the contents of the electronic wallet file read before the previous transaction may be different, and the balance in the electronic wallet file is different because a certain amount of money is deducted from the electronic wallet file after the previous transaction.

Optionally, before the step S230, the method shown in fig. 2 may further include the steps of: and S290, repeatedly outputting an antenna carrier wave opening control signal to the road side unit. Optionally, after the step S230, the method shown in fig. 2 may further include the steps of: s2200, repeatedly outputting an antenna carrier turn-off control signal to the rsu. The embodiment and effect of step S290 are similar to those of step S190, and the embodiment and effect of step S2200 are similar to those of step S1200.

Step S240: and acquiring the result of the re-transaction and the re-read in-card information from the road side unit.

the detailed implementation of this step may be similar to step S240 described above. The difference is mainly that the result of the re-transaction may be different from the transaction result in the previous test, and the card internal information (information read before the current transaction) read again may be different from the card internal information read before the previous transaction.

Step S250: and judging whether the reading of the information in the card is normal again by comparing the information in the card which is read again with the transaction information which is written into the user card at the previous time.

the difference between this step and the above step S250 is mainly that the re-read card information is compared with the transaction information written into the user card during the previous card insertion and extraction test, for example, if the modified composite consumption dedicated file was written during the previous transaction, and the modified electronic wallet file was written during the previous transaction, the composite consumption dedicated file read before this transaction can be compared with the composite consumption dedicated file written into the user card at the previous time, and the electronic wallet file read before this transaction can be compared with the modified electronic wallet file written into the user card at the previous time. The transaction information written in the previous time can be obtained by combining the information read before the previous transaction with the change information which needs to be modified before the roadside unit, for example, the electronic wallet file after the transaction is obtained by subtracting the amount of money to be deducted by the roadside unit in the previous test from the balance in the electronic wallet file read before the previous transaction. In other embodiments, the information to be written to the user card or the information processed in the user card may be transmitted to the execution entity of the method for storage.

Step S260: and judging whether the card plugging of the vehicle-mounted unit is successful again according to the judgment result of whether the obtained card information reading is normal and the result of the re-transaction.

The specific implementation of this step is similar to step S160 described above. For example, if the re-read card information is normal and the re-transaction result is successful, the test may be considered to be successful.

in some embodiments, referring to fig. 2 again, the method for automatically plugging and unplugging an ETC user card according to the foregoing embodiments may further include:

Step S270: and obtaining the successful card plugging and unplugging proportion of the vehicle-mounted unit according to all results of judging whether the card plugging and unplugging of the vehicle-mounted unit is successful so as to judge the read-write stability of the vehicle-mounted unit after the card plugging and unplugging.

For example, the card plugging test may be performed once through the steps S110 to S160, and the card plugging test may be performed multiple times by circularly performing the steps S210 to S260. Each test may yield a successful or failed result. Whether the read-write function of the vehicle-mounted unit is stable after the card is plugged can be judged by counting the ratio of successful tests in all tests.

when it is necessary to evaluate the stability of the same on-board unit, the above steps S110 to S260 may be always performed by one on-board unit. When the next vehicle-mounted unit needs to be tested, the vehicle-mounted unit can be replaced, and the test is started from the beginning again to count the stability of the vehicle-mounted unit.

TABLE 2 plug-in card status

in addition, in order to realize the comparison of the information in the card after the card is inserted and the transaction and the card is pulled out, the retention time can be set through software after the card is inserted and the card is pulled out.

in other embodiments, the present invention relates to a device for detecting whether a card is inserted in place or not and detecting whether the card is pulled out, wherein the device for detecting whether the card is inserted in place or not can detect the state of the card in an electronic tag accurately. In the embodiment, the in-place switch or the infrared probe forms the card position state judgment device, the state information of the card position state judgment device is known by the real-time state of one or more I/O ports on the MCU of the device, the card position information is sent to the industrial personal computer according to a preset rule, and the industrial personal computer finishes subsequent ETC test after acquiring the state information of the card position. When any card in-place detection device is used in the card plugging and unplugging equipment, the states of the detection device obtained by the MCU are three states, and the specific states are shown in the following table 2. The plug-in card state bit is calculated by the state of one or more I/O on the MCU according to the level state judgment algorithm of the position.

In still other embodiments, the test software on the industrial personal computer is different from the traditional ETC test software process, the special RSU for the ETC needs to have the function of switching on and off an antenna to control the card retention time of the card plugging and unplugging device, so that the corresponding function is added, the special RSU for the ETC can be controlled by the test software through an instruction, and meanwhile, the card retention time of the card plugging and unplugging device is set after the test process is finished. In the ETC test flow, because the card position state information is uncertain, the traditional test method can only detect the on-card electricity and on-card state and cannot meet the requirement of the card plugging and unplugging test, so the embodiment reads and compares the three files 0015, 0019 and 0002 in the card in the ETC test flow. The 0015 file is a card issuing basic data file and is written when the card is issued for the second time, and the transaction process cannot be rewritten; 0019 the file is a file special for consumption, and every transaction is modified according to the time, site and other information of the transaction; the 0002 file is an electronic wallet file, the balance of the wallet of the card is recorded, and after each successful fee deduction, the 0002 file can reduce the corresponding fee deduction amount. Before each test, original values of 0015, 0019 and 0002 files can be loaded on test software of an industrial personal computer, according to characteristics of three file transaction processes, the 0015 file cannot be changed, so whether the 0015 file is consistent with the original values or not is judged firstly, when the 0019 file is transacted each time, the 0019 file can be changed according to time and sites, and then the file is judged to be changed; 0002 the file is a wallet file, and if the balance before the transaction is equal to the wallet balance read before the last transaction minus the last transaction amount, the transaction passes.

According to the embodiments, the card plugging and unplugging test can be performed on the ETC vehicle-mounted unit, and the card plugging and unplugging test device is different from the existing other device plugging and unplugging test devices, so that the card reading and writing effect of the vehicle-mounted unit can be automatically verified after the card is plugged; the automatic plug-in card test of the ETC user card can be continuously carried out, and the state of the equipment after multiple plug-ins is verified; the card plugging and unplugging test can be carried out by using different forces and speeds according to the plugging and unplugging habits of different simulated users. The automatic card plugging and unplugging test case solution applicable to the ETC vehicle-mounted unit can verify whether the vehicle-mounted unit read-write card module has problems or not.
