[0031] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments only constitute some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0032] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0033] In an exemplary embodiment, as shown in Fig. 1, a vehicle-mounted data automatic test device is provided, which includes a host computer 2, a bus collector 4, a T-BOX 8, a vehicle cloud server 9 and a network connection platform.

[0034] The host computer 2 is configured to send the data field data of the local test case 1 to the bus collector 4; the local test case 1 includes a vehicle bus data identifier (i.e., CAN ID), data field data, data field analysis data, and a test result.

[0035] The host computer 2 includes a test case reading tool, a bus data transceiving tool, and a bus data analysis tool.

[0036] The test case reading tool is configured to obtain the local test case 1.

[0037] The bus data transceiving tool is configured to send the data field data to the bus collector 4.

[0038] The bus data analysis tool is configured to analyze the T-BOX 8 combined code stream to obtain host computer self-analysis data. The host computer 2 sends data to obtain the data field data in the local test case 1 and sends the data to the bus collector 4 through python-can.

[0039] The local test case 1 (i.e., simulated bus data) is a data table including a vehicle bus data identifier (CAN ID), data field data, data field analysis data, and a test result. The local test case 1 is an Excel-formatted test case.

[0040] For example, a certain local test case 1 is as follows: the vehicle bus data identifier is 0x1CFF9F27; the data field data is: [0x01, 0x01, 0x01, 0x01, 0x30, 0xCF, 0x8C, 0x00]; the data field analysis data is: [′start′, ′pure electric′, ′parking charging′, ′work′, ′neutral′, ′braking force′, ′driving force′, 36047]; and the analysis result is PASS, indicating that the verification is passed.

[0041] The bus collector 4 sends the data field data to the T-BOX 8. The bus collector 4 (i.e., CAN box) is provided with a USB data line, and the bus collector 4 sends the message data (i.e., data field data) required to be sent during the test through the USB connection. The host computer 2 is in communication connection with the bus collector 4 through the USB connection line 3.

[0042] The T-BOX 8 is configured to combine all the data field data according to a protocol to obtain a T-BOX 8 combined code stream. The T-BOX 8 transmits the T-BOX 8 combined code stream to the vehicle cloud server 9 through Ethernet. The T-BOX 8 is connected to the vehicle cloud server 9 in the form of IP and port, and the T-BOX 8 is provided with one GPS antenna and one 4G antenna and a power line bundle 6 and combines the data field data to be sent.

[0043] The vehicle cloud server 9 is configured to send the T-BOX 8 combined code stream to the networked platform. The networked platform is configured to analyze the T-BOX 8 combined code stream to obtain platform analysis data. The networked platform receives and analyzes the reported bus data according to the written analysis function.

[0044] The host computer 2 is further configured to analyze the T-BOX 8 combined code stream to obtain host computer self-analysis data. The host computer 2 obtains the T-BOX 8 combined code stream from the vehicle cloud server 9 and analyzes it according to the protocol to obtain host computer self-analysis data.

[0045] The host computer 2 is further configured to perform assertion comparison on the data field analysis data, the platform analysis data, and the host computer self-analysis data to obtain a test report.

[0046] The platform analysis data is the analysis of the original data reported by the T-BOX 8 to the vehicle cloud server 9, i.e., the analysis of the T-BOX 8 combined code stream forwarded by the vehicle cloud server 9.

[0047] The host computer self-analysis data is the self-analysis of the T-BOX 8 combined code stream forwarded by the vehicle cloud server 9 according to the protocol, i.e., the analysis of the original data reported by the T-BOX 8 to the vehicle cloud server according to the protocol through encoding. Finally, the data field analysis data, the platform analysis data, and the host computer self-analysis data in the simulated bus data are checked for consistency.

[0048] The assertion comparison on the data field analysis data, the platform analysis data, and the host computer self-analysis data to obtain a test report includes the following steps:

[0049] Consistency checking of the data field analysis data, the platform analysis data, and the host computer self-analysis data to obtain a test result.

[0050] If the test result is consistent, a first test result is output, indicating that the data field analysis data, the platform analysis data, and the host computer self-analysis data are consistent, and the first test result indicates that the current test is passed.

[0051] If the test result is inconsistent, a second test result is output, indicating that the data field analysis data, the platform analysis data, and the host computer self-analysis data are inconsistent. The specific situation can be analyzed from the log. If the host computer self-analysis data and the platform analysis data are consistent and the host computer self-analysis data is inconsistent with the data field analysis data, it is highly likely that the TBOX data combination is incorrect or not uploaded in time. If the host computer self-analysis data and the data field analysis data are consistent and the host computer self-analysis data is inconsistent with the platform analysis data, it is a platform analysis data error. If all three are inconsistent, it indicates that the terminal time correction problem or the platform data update problem causes the inconsistency of the analyzed original code stream. The second test result indicates that the current test is failed.

[0052] The problem component can be quickly located through the above test results.

[0053] The vehicle-mounted data automatic test device further comprises a power module configured to provide DC power, i.e., AC power 7, for the T-BOX 8.

[0054] The bus collector 4 is communicatively connected to the T-BOX 8 through the DB9 connecting line 5.

[0055] The DB9 connecting line 5 is provided with four male heads and two female heads. The two female heads are connected to the bus collector 4, and the four male heads are branched from the two female heads and connected to the CAN line of the T-BOX 8.

[0056] After the data of the T-BOX 8 is uploaded, the consistency of the data at the vehicle end and the cloud end is ensured. The current manual test method is obviously time-consuming and laborious, and it is particularly important to find an automatic test method. Therefore, the accuracy and consistency verification automatic verification is performed in the present application, which can improve the test efficiency and test coverage, greatly reduce the uncertain factors caused by human factors in the manual test process, reduce the error rate of manual test; the final test report can be automatically generated; the problem can be attributed according to the output log, and the problem component can be quickly located.

[0058] Step 1: Prepare a local test case 1 containing CANID, data field data, and data field analysis data in the format of excel.

[0059] Step 2: The host computer 2 is connected to the bus collector 4 through the USB connecting line 3.

[0060] Step 3: The bus collector 4 is connected to the CAN line of the T-BOX 8 power harness 6 through the DB9 connecting line 5.

[0061] Step 4: The positive and negative poles of the T-BOX 8 power harness 6 are connected to the AC power 7.

[0062] Step 5: The host computer 2 sends the data field data of the local test case 1 to the bus collector 4 through the program that has been written.

[0063] Step 6: The bus collector 4 receives the data sent in step 5 and forwards it to the T-BOX 8.

[0064] Step 7: The T-BOX 8 sends the received T-BOX 8 combined code stream to the vehicle cloud server 9 through Ethernet.

[0065] Step 8: The vehicle cloud gateway (i.e., the vehicle cloud server 9) forwards the received T-BOX 8 combined code stream to the networked platform.

[0066] Step 9: The networked platform parses the received T-BOX 8 combined code stream to obtain platform parsed data.

[0067] Step 10: The host computer 2 parses the T-BOX 8 combined bus data through the prepared program to obtain host computer self-parsed data.

[0068] Step 11: The host computer 2 obtains the data field parsed data in the use case through the prepared program.

[0069] Step 12: The host computer 2 compares the platform parsed data, the host computer self-parsed data, and the data field parsed data in the use case through the prepared program, and automatically generates a test report through the prepared program.
