Description

Technical Field

[0001] The present invention belongs to the technical field of functional testing of multi-vehicle collaborative operations, and in particular relates to a comprehensive testing system and method for multi-vehicle collaborative operations. Background Art

[0002] At present, the equipment of various military services is developing from independent combat of a single person and a single vehicle to collaborative combat of multiple people and multiple vehicles. The complexity of the system and the functional scenarios are also increasing exponentially. The requirements for system testing are also getting higher and higher, and it brings huge challenges to the quality and efficiency of traditional testing. The single mode of sending control instructions and collecting data for interpretation can no longer meet the testing needs. Existing test methods and test equipment are mainly aimed at specific protocols and special equipment. There is a lack of products for multi-vehicle collaborative operation processes and functional testing. Multiple stimulus injections and multi-channel data acquisition cannot be implemented in one system or device at the same time. At the same time, the system development and production cycle is getting shorter and shorter, which puts higher requirements on the test system. It must not only be able to test the self-closed loop function of a single vehicle, but also the collaborative operation process of multiple vehicles. Summary of the invention

[0048] Example 1

[0049] This embodiment provides a comprehensive testing method for multi-vehicle collaborative operation, which includes the following implementation steps:

[0050] S1: Establish a basic element library. In the test case management unit library configuration interface, enter the element name through the Add button to add a new element. Select the category and icon according to the element attributes. Fill in the Set / Get, reference, name, code, display type, content, range and other fields according to the actual business nature. After the content is added, save it to complete the establishment of a basic element. According to the business process requirements of multi-vehicle collaborative operations, establish the required elements in sequence. After the element library is built, it only needs to be maintained when the test requirements change, which greatly facilitates designers to quickly build new test cases and avoid a lot of repetitive work;

[0051] S2: Establish a basic module library: Create a module library through the test case management module. First, name the new module "1 Car display and control sends command message to planning (1)", drag the command message collection element from the element library list to the combination interface, enter the collected command message content, use an arrow to point to the next protocol parsing element, and configure the field name, meaning, data type, number of bytes, and remarks information according to the command message protocol. After each field is configured, use an arrow to point to the print display element. After all fields are configured, the arrow points to the end element, indicating that the internal action of the module is completed. Finally, it points to the result generation element, and the single module is created. According to the information flow of the multi-vehicle collaborative system, the modules "1 vehicle planning feedback command message to display control (1)", "1 vehicle display control sends command message to planning (2)", "1 vehicle planning feedback command message to display control (2)", "1 vehicle planning sends command message to multiple elements", "1 vehicle multiple elements feedback command message to planning", "1 vehicle multiple elements send cross-vehicle command message to 2 vehicle planning", "2 vehicle planning sends command message to multiple elements", "2 vehicle multiple elements feedback command message to planning", "2 vehicle multiple elements send cross-vehicle command message to 3 vehicle collaboration", and "3 vehicle collaboration feedback command message to 2 vehicle multiple elements" are created in sequence.

[0053] S4: Create a new test project: In the test case management-project management interface, select the test case created in step S3 according to the multi-vehicle collaborative operation process, drag the test cases required for this test project to the visual modeling interface, and refer to the collaborative operation file to arrange the test cases that can be executed simultaneously in parallel, and the test cases that cannot be executed simultaneously in series, and connect them with vector arrows to create a project for this test. In the parallel execution mode, processing threads will be created according to the number of parallel execution of the test cases. Each thread will read the data required in its own process from the memory at the same time. When a memory is read, it will be cleared to ensure memory availability and test fluency.

[0054] S5: Create a new system under test information in the test process control module, enter the system under test number, test project name, and test location, select the built test case project in the load test case library to load, see the "Multi-vehicle collaborative operation process test" project on the test interface, click to execute the test, and complete the personnel operation on the system under test according to the multi-vehicle collaborative operation process. The acquisition module will collect the command messages generated by the system under test in real time and send them to the analysis module. The analysis module will parse the collected binary array according to the configured protocol and print it out to the display interface for display. The parsed data will be forwarded to the interpretation module at the same time. According to the interpretation rules set in step S2, the data interpretation is completed and the test results are printed out. The acquisition information, parsing information, and interpretation result information will all be fed back to the display module for display. The display interface will display the real-time refreshed brief test process information with timestamps, the detailed input information parsed according to the data protocol, the comparison process information of the multi-vehicle collaborative information flow outbound data and inbound data, and the test result information after the test case is executed.

[0055] S6: After the test is completed, click the report generation button of the test process control module, select the generated report format, and output the test report. The test process data and log information are stored in the database and can be viewed and exported through the test information management module.

[0056] If the test process that has just been completed needs to be reviewed, the playback function of the test process control module can be used to dynamically playback the test process and the display interface data printout process, making it convenient for testers to review, avoid missing important information, and ensure the correctness of the test process.

[0057] S7: The test case management module copies the existing module library and case library information, modifies the name, attributes, and collection objects, and re-drags and combines them to quickly form new test cases.

[0058] S8: The test process control module can create new information about the system under test, enter a new number, load the established test cases, and directly conduct tests to form a test database and report library for the new system.
