[0037] The Cooperative Intelligent Transport System, the application layer of the vehicle communication system, and the application data interaction standard standardize the communication in the related field, and in order to ensure the accuracy and consistency of the communication data, the related message set meeting the above interaction standard needs to be tested, but at present, only part of the message set has been tested, and the full coverage test of the related message set has not been realized, and meanwhile, the acquisition of the test data of the related message set and the test process are inconvenient and imperfect in actual application. Therefore, the embodiments of the present disclosure provide a vehicle message test method, a system, and a computer readable storage medium, which are used to realize the full coverage test of the related message set, reduce the difficulty of acquiring the test data of the related message set, improve the automation of the test, and facilitate the use of the test personnel.

[0038] Figure 1 A flowchart of a vehicle message test method according to an embodiment of the present disclosure is shown as follows, Figure 1 The method includes the following steps.

[0039] S101: generating message test data, the message test data is used to test any message in a preset message set, the preset message set includes all message subsets meeting the target standard in each stage, and the target standard is the Cooperative Intelligent Transport System, the application layer of the vehicle communication system, and the application data interaction standard.

[0040] The message test data of the present disclosure can be a conventional type of data, a linked list type of data, or a joint type of data, the preset message set of the present disclosure can be the Basic Safety Message (BSM) of the vehicle, the Map Message (MAP) of the vehicle, the Roadside Safety Message (RSM) of the vehicle, the Signal Light Message (SPAT) of the vehicle, the traffic event information and traffic sign information (RS I) published by the roadside unit to the surrounding vehicle unit, the private message format (TEST) for testing, the correction information (RTCM), the message (RSC) for vehicle cooperation or guidance by the roadside unit, the perception sharing message (SSM) of the traffic participant, the road obstacle, and the traffic event, the vehicle intention and request message (VIR), the message (PAM) of the internal map of the station, the basic safety message (PSM) of the vulnerable traffic participant (pedestrian, non-motor vehicle), the connectionless vehicle fleet management message (CLPMM), and the vehicle payment message (VPM) of the vehicle, and the Cooperative Intelligent Transport System, the application layer of the vehicle communication system, and the application data interaction standard of the present disclosure mainly refer to the Cooperative Intelligent Transport System, the application layer of the vehicle communication system, and the application data interaction standard numbered T / CSAE 53-2020 and T / CSAE 157-2020.

[0041] In an embodiment, the tester selects a message set to be tested in the current test according to test requirements, the message set is VPM from 14 message sets conforming to the Cooperative Intelligent Transport System, Vehicle Communication System Application Layer and Application Data Interaction Standard published by the Society of Automotive Engineers of China, and the first test device generates corresponding message test data according to the selected message set VPM.

[0042] In some embodiments of the present disclosure, the generating the message test data further includes the steps of: Figure 2

[0043] S201: Display a test data configuration interface.

[0044] In an embodiment of the present disclosure, the test data configuration interface is as shown in Figure 3 The interface includes a message subset selection control and a generation mode selection control.

[0045] S202: Select a message subset to be tested in the message subset selection control.

[0046] As can be seen from the above, the message subset selection control can select at least one message subset for testing, and the selectable message subset of the message selection control includes the above-mentioned 14 message sets conforming to the Cooperative Intelligent Transport System, Vehicle Communication System Application Layer and Application Data Interaction Standard published by the Society of Automotive Engineers of China.

[0047] In some embodiments, the message subset selection control can be composed of sub-controls corresponding to the 14 message sets, and the tester can select a message set by triggering the sub-control corresponding to the message set.

[0048] S203: Select a generation mode in the generation mode selection control.

[0049] In an embodiment of the present disclosure, the tester selects a generation mode in the generation mode selection control of the test data configuration interface, and the first test device generates message test data corresponding to the message subset selected in the previous step based on the generation mode selected by the tester.

[0050] In some other embodiments of the present disclosure, the indication result of the generation mode selection control includes a first generation mode and a second generation mode, and the first test device generates corresponding message test data based on the first generation mode or the second generation mode. The first generation mode means that the message test data is specified in a custom manner, and the second generation mode means that the message test data is automatically generated in a random manner. As shown in Figure 4 When the indication result of the generation mode selection control is the first generation mode, the first test device generates a standard template file corresponding to the target message subset based on the target message subset determined in the previous step, and obtains corresponding message test data based on the editing result of the template file.​Figure 5 As shown, when the result of the generation mode selection control indicates the second generation mode, the first test device acquires data generation reference information and automatically generates message test data conforming to the standard corresponding to the target message subset based on the data generation reference information.

[0051] S204: Generate message test data based on the selected message subset and the generation mode.

[0052] In a specific embodiment, the message subset selected by the test personnel is message set A, which represents any message subset of the 14 message sets, and the selected generation mode is the first generation mode. The first test device generates message test data corresponding to message set A based on message set A and the first generation mode as follows: the first test device generates structured data of message set A conforming to the cooperative intelligent transportation system, application layer and application data interaction standard for vehicle communication systems published by the Society of Automotive Engineers of China, and then generates an XML file (XML can be used to mark data and define data types) corresponding to message set A according to the data name, data value and data nesting relationship in the generated structured data. At this time, the XML file is the template file, and the test personnel can edit the template file, i.e., the XML file, at this time, including setting specified data and other operations, to obtain message test data corresponding to message set A in this test.

[0053] In some embodiments, the XML file can be parsed and displayed by the first test device, and the test personnel can see the detailed information of the structured data contained in the XML on the display interface and can also edit it.

[0054] In another specific embodiment, the message subset selected by the test personnel is message set B, which represents any message subset of the 14 message sets, and the selected generation mode is the second generation mode. The first test device generates message test data corresponding to message set B based on message set B and the second generation mode as follows: the test personnel sets data generation reference information according to test requirements. In this embodiment, the data generation reference information includes data range and parameters of a data model conforming to the standard corresponding to message set B. The data model includes a linked list or a union. Specifically, for regular data, the maximum value, minimum value and random value can be set, the linked list data can be set to the maximum value, minimum value and random value of the linked list number, and the union data can be set to the unique value and random value. The first test device automatically generates message test data corresponding to message set B based on the data generation reference information.

[0055] From the above, through S201 to S204, the tester can select the message set to be tested based on the message subset selection control in the test data configuration interface, and specify the generation mode of the message test data based on the generation mode selection control, which can enable the tester to visually interact with the first test device, and also diversify the message test data generation mode to meet different testing requirements.

[0056] S102: Send the message test data to the device under test to trigger the device under test to send the message test data to the second test device based on the application under test, and the second test device is configured to transmit the received data to the first test device.

[0057] In an embodiment, the tester selects a message subset C, and the generation mode of the message subset C is the first generation mode. The first test device generates the corresponding message test data based on the message subset C and the first generation mode, and then sends the message test data to the device under test through a wireless local area network. After receiving the message test data, the device under test sends the message test data to the application under test according to the interface format of the application under test. After receiving the message test data, the application under test sends the data to the second test device through the air interface. The second test device is also configured with the same application under test as the device under test. After receiving the data sent by the application under test of the device under test through the air interface, the second test device transmits the received data to the first test device through a wireless local area network.

[0058] S103: Based on the message test data and the data received from the second test device, the test result corresponding to the application under test in the device under test is obtained.

[0059] The first test device compares the data sent by the second test device through the wireless local area network with the message test data. If the two data are consistent, the test result indicates that the communication is normal. If the two data are inconsistent, the test result indicates that the communication is not normal.

[0060] In a specific embodiment, the application to be tested is a V2X module in the field of vehicle communication. V2X, i.e. Vehicle to Everything / Vehicle to X, is a vehicle wireless communication technology, which is intended to be centered on vehicles, to communicate with surrounding vehicles, devices and base stations, so as to obtain real-time traffic information such as real-time road conditions, road information and pedestrian information, so as to improve driving safety, reduce congestion, improve traffic efficiency and provide vehicle entertainment information, and is a key technology of future intelligent transportation systems. The first test device generates relevant message test data according to test requirements, and sends the message test data to the device to be tested through a wireless local area network. The device to be tested sends the message test data to the V2X module according to the communication interface format of the V2X module. The V2X module sends the message test data to the V2X module of the second test device through the air interface. The second test device transmits the received data to the first test device through the wireless local area network. The first test device compares the message test data with the data transmitted by the second test device, and determines whether the communication of the V2X module is normal. When the comparison result is inconsistent, it indicates that the communication between the V2X modules is not normal. When the comparison result is consistent, it indicates that the communication between the V2X modules is normal, and the test result of the application to be tested on the device to be tested is obtained.

[0061] As can be seen from the above, the first test device and the device to be tested transmit data through a wireless local area network. The wireless local area network has good data transmission effect and high data transmission accuracy, which can ensure that the message test data sent by the first test device to the device to be tested is correct. The device to be tested and the second test device transmit data through the application to be tested. The second test device and the first test device transmit data through a wireless local area network, which can also ensure the accuracy of data transmission. Therefore, when the comparison result of the first test device is inconsistent, it indicates that the data transmission between the device to be tested and the second test device is incorrect. The device to be tested and the second test data communicate based on the application to be tested, which indicates that the test result of the application to be tested is based on the communication of the target message subset selected in the test. Conversely, when the comparison result of the first test device is consistent, it indicates that the communication is normal.

[0062] In some embodiments of the present disclosure, as Figure 6 Before generating the message test data, the following steps are further included: displaying a control parameter configuration interface, the control parameter configuration interface including a time control and a data volume control. When the time control in the control parameter configuration interface is triggered, a test duration parameter is obtained, which is used to limit the test duration. When the data volume control in the control parameter configuration interface is triggered, a test data volume parameter is obtained, which is used to limit the upper limit value of the generated message test data.

[0063] In a specific embodiment, the tester triggers the time control, sets the test duration to 10 minutes, and the test is automatically stopped when the test duration reaches 10 minutes.

[0064] In another specific embodiment, the tester triggers the data volume control, sets the upper limit of the generated message test data to 100, and the first test device generates 100 test data. After the test of the 100 test data is completed, the test is automatically stopped.

[0065] Through the time control and the data volume control, the tester can set the test stop condition according to the test requirements before the test starts. When the test stop condition is reached, the test is automatically stopped, and the tester does not need to frequently operate during the test. Therefore, the automated test provided by the present disclosure is convenient for the tester to use in practice, and has high practicability.

[0066] Figure 7 A frame diagram of a vehicle message test system according to an embodiment of the present disclosure is shown. As shown in the figure, the vehicle message test system provided by the present disclosure includes a first test device, a device under test, and a second test device. The system provided by the present disclosure is suitable for the vehicle message test method of any one of the above embodiments provided by the present disclosure. As shown in the figure, the communication mode between the first test device and the device under test is a wireless local area network, the communication mode between the device under test and the second test device is air interface communication, and the communication mode between the second test device and the first test device is a wireless local area network. Through the system, the above message test data can be generated by the first test device, sent to the device under test through the wireless local area network, sent to the second test data by the device under test through the air interface communication, and finally returned to the first test device through the wireless local area network by the second test device. In this way, a closed loop of data transmission is completed, and the test result is obtained by comparing the sent and received data by the first test device.

[0067] The working processes of the first test device, the device under test, and the second test device will be described in detail below. Figure 8 , 9 , 10

[0068] As Figure 8As shown, this is a functional flow chart of the first test device. First, the first test device determines a target message subset; second, determines a generation mode. When the generation mode is the first generation mode, a template file of the target message subset is generated, and the template file is edited to generate message test data for the target message subset. When the generation mode is the second generation mode, data generation reference information is obtained, and corresponding message test data is generated based on the selected target message subset and the data generation reference information; third, control parameters are set. When the time control is triggered, the maximum test duration can be set. When the test duration reaches the maximum duration, the test automatically stops. When the data volume control is triggered, the maximum test data volume can be set. When the message test data reaches the maximum data volume, the test automatically stops; in the third step, the generated message test data is sent to the device under test via a wireless local area network; fourth, the data sent by the second test device is received via the wireless local area network; fifth, the received data is compared with the generated message test data to obtain a test result. When the received data is consistent with the generated message test data, the test result indicates that the communication is normal. When the received data is inconsistent with the generated message test data, the test result indicates that the communication is abnormal.

[0069] like Figure 9 As shown in the figure, it is a functional flow chart of the device under test. First, the device under test receives the message test data sent by the first test device through the wireless local area network; second, the device under test transmits the received message test data to the application under test according to the communication format of the application under test located on the device under test; third, the application under test sends the message test data to the second test device through the air interface.

[0070] like Figure 10 As shown, this is a functional flow chart of the second test device. First, the second test device receives data sent by the test application on the device to be tested through the application to be tested and the air interface configured thereon; second, the second test device transparently transmits the received data to the first test device through the wireless local area network.
