Further, in FIG. 1, only one simulation test environment system 1 and one lane server 4 are shown, but it may be possible to connect to a plurality of lane servers 4 and perform tests in parallel.

[0012] First, the configuration of the lane server 4 to be tested will be described. The lane server 4 is a server connected to a roadside device (not shown) provided for each lane of the toll booth and an upper toll booth server (not shown). The lane server 4 uses the toll table distributed from the upper device (not shown) of the toll system via the toll booth server, performs toll calculation and the like based on the communication result with the vehicle passing through the lane of the toll booth, and transmits it to the toll booth server. Here, the toll table used for toll calculation may be stored in the upper device or the like, and may be queried to the upper device each time toll calculation is performed. Here, only the configuration related to the operation of the simulation test environment system 1 is described for the configuration of the lane server 4, and other configurations are omitted in both the description and the illustration.

[0016] The system clock 43 is a system clock that manages the time that serves as the reference time for the operation of the lane server 4. Based on a time change instruction transmitted from the test control device 2, the system clock 43 changes the current time, thereby skipping the operation of the lane server 4 to an arbitrary time, and the lane server 4 operates based on the skipped time.

[0017] Next, we will explain the configuration of the mock examination environment system 1. The simulated test environment system 1 comprises a test control device 2 and an IF (interface) conversion device 3.

[0018] The test control device 2 comprises a data generation unit 21, a test information management unit 22, a tollbooth server simulator (hereinafter referred to as the tollbooth server SIM) 23, and a communication unit 24. For example, the test control device 2 can be configured by one or more computers, and each part of the test control device 2 and the simulator are composed of hardware such as one or more processors, memory, and communication interfaces.

[0019] The communication unit 24 is a communication unit that receives input information from the management device 5.

[0020] The data generation unit 21 is a generation unit that generates setting data, vehicle data, and vehicle behavior data as test data based on input information, etc., and transmits them to the IF conversion device 3. Here, the configuration data is data related to the toll booths that the vehicle has passed through, and includes toll booth identification information to identify the toll booths. The vehicle data is data corresponding to the signals transmitted from the on-board unit of the vehicle traveling in the toll booth's lane. The vehicle behavior data is data corresponding to the signals output from multiple vehicle detectors installed along the toll booth's lane. Details of the test data will be explained in detail in the operation description.

[0021] The test information management unit 22 receives the test time notification transmitted from the test planning unit 31 of the IF converter 3, and sends a time change instruction to synchronize the system clock 34 of the IF converter 3 and the system clock 43 of the lane server 4 based on the test time notification. Details of time synchronization and the role it plays will be explained in detail later.

[0022] The tollbooth server SIM23 receives and stores the detailed data transmitted from the lane server 4 under test. This detailed data represents the results of a simulated test generated by the lane server 4, and based on this data, the appropriate toll is calculated according to the vehicle type, driving section, etc. but calculation Whether it is being done verification vinegar ru.

[0023] Next, the interface conversion device (hereinafter referred to as IF conversion device) 3 comprises a test planning unit 31, an antenna SIM 32, a vehicle behavior SIM 33, a system clock 34, and a communication unit 35. For example, the IF conversion device 3 can be configured by one or more computers, and each part of the IF conversion device 3 and each simulator are composed of hardware such as one or more processors, memory, and communication interfaces.

[0024] The test planning department 31 is, The data generated by the data generation unit 21 This is a planning unit that generates a simulated test plan based on the aforementioned test data, including setting data, vehicle data, and vehicle behavior data. Furthermore, the test planning unit 31 is When conducting a mock exam Send configuration data to lane server 4. Furthermore, the test planning unit 31 sends a test time notification to the test control device 2 and receives a time change instruction from the test control device 2. After the time on the system clock 34 is changed based on the time change instruction, the test planning unit 31 sends vehicle data to the antenna SIM 32 and vehicle behavior data to the vehicle behavior SIM 33 based on the simulated test plan. The generation of the simulated test plan and other related matters will be explained in detail later.

[0025] Antenna SIM32 is located in the toll booth lane. In Onboard devices of passing vehicles Communicate with This is a simulator that simulates an antenna. In the simulated test environment system 1, the antenna SIM32 communicates with the lane server 4 based on communication protocols such as TCP / IP (Transmission Control Protocol / Internet Protocol). Antenna SIM32 generates UP data based on vehicle data and transmits the UP data to lane server 4. vinegar ru. Here, UP data corresponds to signals transmitted from the antennas of on-board devices in vehicles traveling through toll booth lanes. do . Furthermore, antenna SIM32 receives DOWN data (vehicle attribute data) from lane server 4. Here, DOWN data corresponds to the signal received by the in-vehicle device's antenna. Although the signals transmitted from and received by the in-vehicle device's antenna are encrypted, in this practice test, UP data and DOWN data will be in plain text.

[0026] The vehicle behavior simulator 33 is a simulator that simulates the operation of one or more vehicle detectors installed along the lanes of a toll booth. In the simulated test environment system 1, the vehicle behavior simulator 33 communicates with the lane server 4 based on a communication protocol such as TCP / IP. The vehicle behavior SIM33 generates a contact signal based on vehicle behavior data and transmits the contact signal to the lane server 4. The contact signal corresponds to a vehicle detection signal output from one or more vehicle detectors. In this embodiment, the contact signal is assumed to be a vehicle detection signal output from multiple vehicle detectors.

[0027] The system clock 34 is the system clock of the IF converter 3. The system clock 34 changes its time based on a time change instruction transmitted from the test control device 2. That is, the system clock 34 skips the current time to an arbitrary time based on the time change instruction transmitted from the test control device 2, and the IF converter 3 operates based on the skipped time.

[0028] Next, the flow of data, signals, notifications, and instructions in a simulated test of the simulated test environment system according to the embodiment will be described. Figure 2 shows the flow of data, signals, notifications, and instructions in a simulated test of the simulated test environment system according to the embodiment. As shown in Figure 2, the processes performed in the simulated test environment system include: "test data generation process," "test planning process," "test start process," "time processing," "time synchronization process," "contact signal transmission process," "UP data transmission process," "DOWN data reception process," and "detail data reception process." The following explains each process. [Test data generation process] first, This section explains the process for generating test data. Test control device 2 teeth, For IF converter 3 trial The system performs the transmission of test data. Specifically, the data generation unit 21 of the test control device 2 performs the transmission of input information etc. from the management device 5. Generated test data The system then transmits setting data, vehicle data, and vehicle behavior data to the test planning unit 31 as test data.

[0029] Figure 3 is a flowchart showing an example of the test data generation process. As shown in Figure 3, in ST11, Test control device 2 The data generation unit 21 loads configuration data, including tollbooth identification information, which identifies the tollbooth. Next, in ST12, Test control device 2 The data generation unit 21 registers vehicle data.

[0030] Figure 4 shows an example of vehicle data. Vehicle data is one type of test data and corresponds to the signals transmitted from the onboard unit of a vehicle traveling in the toll booth lane. Vehicle data includes vehicle identification information and vehicle information. Vehicle information includes vehicle type and ETC card number, etc.

[0031] Returning to Figure 3, in ST13, the data generation unit 21 registers the vehicle behavior data in chronological order.

[0032] Figure 5 shows an example of vehicle behavior data. Vehicle behavior data is a type of test data, corresponding to signals output from multiple vehicle detectors installed along the traffic lanes of a toll booth. The vehicle behavior data includes multiple records corresponding to vehicle detection signals output at predetermined intervals from the multiple vehicle detectors. Each record includes behavior identification information, occurrence time (including year, month, and day), vehicle identification information, and vehicle detection information. Based on the vehicle identification information included in the vehicle data and the vehicle identification information included in the vehicle behavior data, it is possible to associate the vehicle data with the vehicle behavior data. For example, the occurrence time can be recorded down to microseconds (ms).

[0033] Here, we will provide additional information on the installation of vehicle detectors and explain the details of vehicle behavior data. For example, three vehicle detectors S1, S2, and S4, of the reflective or transmissive type, are installed sequentially from upstream to downstream in a traffic lane, and vehicles travel along the lane from upstream to downstream. When a vehicle travels in a lane, The three vehicle detectors S1, S2, and S4 output vehicle detection signals at predetermined intervals. They output an ON signal when a vehicle is detected and an OFF signal when no vehicle is detected.

[0034] Focusing on the behavior identification information 1-6 shown in Figure 5, it can be seen that, in accordance with the movement of the vehicle from upstream to downstream, the output of vehicle detector S1 turns on, the output of vehicle detector S2 turns on, the output of vehicle detector S1 turns off, the output of vehicle detector S2 turns off, the output of vehicle detector S4 turns on, and the output of vehicle detector S4 turns off in a time series.

[0035] Returning to Figure 3, in ST14, Test control device 2 The data generation unit 21 is: IF converter 3 The setting data, vehicle data, and vehicle behavior data are transmitted to the test planning unit 31 as test data.

[0036] [Test planning process] Next, regarding the test plan processing, Let's return to Figure 2 and explain it again. The test planning process is as follows:The test planning unit 31 of the IF conversion device 3 is a processing unit that performs test planning in order to format the saved setting data and send it to the lane server 4. Here, the test planning processing is the process by which the test planning unit 31 sends the setting data from the received data to the lane server 4. 。

[0037] Figure 6 is a flowchart showing an example of the test planning process. As shown in Figure 6, in ST41, IF converter 3 The test planning unit 31 receives information from the test control device 2. Received It saves configuration data, vehicle data, and vehicle behavior data.

[0038] In ST42, IF converter 3 The test planning unit 31 formats the saved configuration data and sends it to the lane server 4.

[0039] In ST43, IF converter 3 The test planning unit 31 analyzes the vehicle behavior data and sorts the multiple records included in the vehicle behavior data in chronological order based on their occurrence times. For example, as shown in Figure 5, the test planning unit 31 sorts the multiple records included in the vehicle behavior data in chronological order.

[0040] In ST44, IF converter 3 The test planning unit 31 detects the interval between occurrences of multiple records based on the occurrence times of multiple records included in the vehicle behavior data. And then. Among the detected occurrence intervals, those that exceed the threshold for no vehicle traffic are detected as periods without vehicle traffic.

[0041] Here, the threshold for no vehicle traffic is: Management device 5 from Set according to the examiner's input. .and, No vehicle traffic threshold teeth Input to IF converter 3 And so, The test planning unit 31 of the IF conversion device 3 stores the input vehicle traffic absence threshold. Here,Assuming a vehicle-free threshold of 10 minutes, for the vehicle behavior data shown in Figure 5, the test planning unit 31 detects that the period between the record of behavior identification information 6 and the record of behavior identification information 7 exceeds the vehicle-free threshold of 10 minutes, and therefore detects this period as a time period without vehicle traffic. Note that the vehicle-free threshold is an arbitrary value, and the degree to which the test time is shortened can be adjusted by setting a desired value.

[0042] In ST45, IF converter 3 The test planning unit 31 groups these multiple records based on the detected time periods when there was no vehicle traffic.

[0043] The vehicle behavior data shown in Figure 5 is as follows: IF converter 3 The test planning unit 31 handles behavior identification information 1 to 6 of The records are grouped into one, and behavior identification information 7-12 of The records are grouped into one. Multiple records belonging to one group represent the behavior of one or more vehicles. In the case of Figure 5, all of the behavior identification information 1 to 6 are the same vehicle identification information, so they represent the behavior of one vehicle. Also, all of the behavior identification information 7 to 12 are the same vehicle identification information, so they also represent the behavior of one vehicle.

[0044] Figure 7 shows an example of traffic time information. Traffic time information is information generated in the grouping process of the test planning unit 31, and includes traffic time identification information, the time of occurrence of the first behavior data (including year, month, and day), the time of occurrence of the last behavior data (including year, month, and day), and the test start time (including year, month, and day). Traffic time identification information 1 is generated by grouping multiple records of the behavior identification information 1 to 6 into one, and traffic time identification information 2 is generated by grouping multiple records of the behavior identification information 7 to 12 into one.

[0045] Returning to Figure 6, at ST46, IF converter 3 The test planning unit 31 generates a test plan to be executed on a group basis, based on the grouping results and the specified test mode. Here, the test mode is, management device 5 from It is specified according to the examiner's input. It is Skip test mode or non-skip test mode There is. Here, The skip test mode skips the detected period of no vehicle traffic, while the non-skip test mode does not skip the detected period of no vehicle traffic. The test mode specified by the control device 5 is input to the IF converter 3.

[0046] IF converter 3 The test planning unit 31 specifies the skip test mode. If that happens This generates a skip test plan that skips time periods without vehicle traffic. If the vehicle behavior data is as shown in Figure 5, the test planning unit 31 will execute tests based on behavior identification information 1 to 6 in order of occurrence time, skip the period between behavior identification information 6 and behavior identification information 7 (from 2023 / 01 / 24 10:18:12 to 2023 / 01 / 24 10:30:05), and generate a skip test plan that executes tests based on behavior identification information 7 to 12 in order of occurrence time. This skip test mode allows for a reduction in test time by skipping the period between behavior identification information 6 and behavior identification information 7.

[0047] Also, IF converter 3 The test planning unit 31 specifies the non-skip test mode. If that happens This generates a non-skip test plan that does not skip time periods without vehicle traffic. If the vehicle behavior data is as shown in Figure 5, the test planning unit 31 generates a non-skip test plan that executes tests based on behavior identification information 1 to 12 in order of occurrence time. This non-skip test mode allows tests to be executed in real time.

[0048] In ST47, IF converter 3 The test planning unit 31 determines whether or not there are any untested traffic time slots. If the answer to ST47 is Yes, the process moves to ST48, and the test planning unit 31 conducts tests for the untested designated traffic time slots. If the vehicle behavior data is as shown in Figure 5, tests are conducted for the untested traffic time slots of behavior identification information 1 to 6, and then tests are conducted for the untested traffic time slots of behavior identification information 7 to 12.

[0049] If ST47 is No, the test planning unit 31 terminates the test. If the vehicle behavior data is as shown in Figure 5, the test will terminate once the traffic time periods for behavior identification information 1-6 and behavior identification information 7-12 have been tested.

[0050] [Test Start Process] Next, we will explain the test initiation process. Returning to Figure 2, 、 During the test initiation process, IF converter 3 The test planning unit 31 detects the earliest time included in multiple records belonging to a predetermined group and sends a test time notification to the test information management unit 22, which includes the test start time corresponding to this earliest time.

[0051] Figure 8 shows IF converter 3 This flowchart shows an example of the test start process and time synchronization process. In Figure 8, ST51 teeth An example of the test start process Therefore, ST52~ST59 is an example of time synchronization processing. This indicates. As shown in Figure 8, in ST51, IF converter 3 The test planning unit 31 detects the earliest time included in multiple records belonging to a predetermined group and sends a test time notification to the test information management unit 22 of the test control device 2, which includes the test start time corresponding to this earliest time.

[0052] Figure 9 shows an example of an exam time notification. The test time notification is a notification based on the test plan generated by the test planning unit 31 and is sent from the IF converter 3 to the test control device 2. The test time notification includes the name of the IF converter, the notification time (including year, month, and day), and the test start time (including year, month, and day). figureIf the vehicle behavior data is as shown in 5, the earliest time (2023 / 01 / 24 10:13:05) included in the behavior identification information 1-6 belonging to the first group will be detected. Alternatively, the earliest time (2023 / 01 / 24 10:30:05) included in the behavior identification information 7-12 belonging to the second group will be detected.

[0053] The test information management unit 22 generates a time change instruction to change the time to a predetermined time immediately preceding the test start time, based on the test start time included in the test time notification, and sends the time change instruction to the test planning unit 31 and the lane server 4.

[0054] [Time processing] Next, we will explain time processing. Returning to the explanation of Figure 2, And here, time processing by time information management function This synchronizes the time between the test control device 2 and the IF converter 3. It is a process. In time processing, Test control device 2 The test information management unit 22 generates a time change instruction to change the time to a predetermined time immediately preceding the test start time, based on the test start time included in the test time notification, and sends the generated time change instruction to the lane server 4. Also, as explained in ST37, the test information management unit 22 sends the generated time change instruction to the test planning unit 31.

[0055] Figure 10 shows In the test control device 2 This flowchart shows an example of time processing using the time information management function. As shown in Figure 10, in ST31, Test control device 2 The test information management unit 22 switches to waiting for the reception of communication messages. In ST32, Test control device 2 The test information management unit 22 determines whether or not a communication message has been received.

[0056] If the answer is No in ST32, Test control device 2 The test information management unit 22 continues to wait for reception unless it receives a communication message. If the answer to ST32 is Yes, the process proceeds to ST33, where the test information management unit 22 determines whether the content of the received communication message is a test time notification or a test completion notification. A test time notification includes information such as the name of the IF converter from the sender, the notification time, and the test start time.

[0057] If ST33 is No, the system switches to waiting for a communication message to be received and waits for the message to be received. If the answer to ST33 is Yes, proceed to ST34. Test control device 2 The test information management unit 22 determines whether the message content is a test time notification or not.

[0058] If ST33 is No, and the message content is a termination notification, the process will be terminated. If the answer to ST34 is Yes, the process proceeds to ST35, and the examination information management unit 22 records the examination time notification.

[0059] In ST36, Test control device 2 The test information management unit 22 generates a time change instruction to change the time to a predetermined time immediately preceding the test start time, based on the test start time included in the test time notification, and sends the generated time change instruction to the lane server 4. In ST37, Test control device 2 The test information management unit 22 transmits the generated time change instruction to the test planning unit 31. Furthermore, the transmission of the time change instruction to the lane server 4 in ST36 and the transmission of the time change instruction to the test planning unit 31 in ST37 are performed essentially simultaneously.

[0060] Test control device 2 The test information management unit 22 generates test management information in response to the transmission of a time change instruction. Figure 11 shows an example of test time management information. The test time management information is generated by the test planning unit 31 and includes the IF conversion device name, notification reception time (including year, month, and day), test start time (including year, month, and day), time of sending the time change notification to the lane server 4 (including year, month, and day), and time of sending the time change notification to the test control device 2 (including year, month, and day).

[0061] [Time synchronization process] Next, we will explain the time synchronization process. Returning to Figure 2, , IF converter 3 The test planning unit 31 performs time synchronization processing. In time synchronization processing, the test planning unit 31 performs: From the test information management unit 22 of the test control device 2 Based on the time change instruction, the time is synchronized with lane server 4. And, Untested lead vehicle behavior data is transmitted to the vehicle behavior SIM33, and the untested lead vehicle behavior data and related vehicle data are transmitted to the antenna SIM32. again, Figure 8 Returning to the IF converter 3 An example of test start processing and time synchronization processing Let me explain. In Figure 8, ST52 to ST59 show an example of time synchronization processing.

[0062] In ST52, IF converter 3 The test planning department 31 is, Test control device 2 The system receives a time change instruction transmitted from the test information management unit 22.

[0063] In ST53, IF converter 3 The test planning unit 31 outputs an instruction to change the time of the system clock 34 to a predetermined time based on the time change instruction transmitted from the test information management unit 22. do. In response to this The system clock 34 changes its time to the predetermined time based on the change instruction from the test planning unit 31. At the same time, the system clock 43 of the vehicle server 4 also changes its time to the predetermined time based on the time change instruction transmitted from the test information management unit 22. This time change instruction twist The system clock 34 of the IF converter 3 and the system clock 43 of the vehicle server 4 are synchronized.

[0064] In ST54, IF converter 3 The test planning unit 31 reads vehicle data and vehicle behavior data for the untested designated traffic time period. If the vehicle behavior data is as shown in Figure 5, then behavior identification information 1 to 6 or behavior identification information 7 to 12 for the untested designated traffic time period are read.
