[0061] During the product identification process, the barcode scanning, RFID and visual identification results are mutually verified. If the product information does not match or the identification is abnormal, an early warning is automatically triggered to notify the management staff for verification;

[0062] S3: Test plan matching: formulate a serial time-sharing automated production line test plan based on the type of product to be tested and the test requirements, and build a specific test process. The test process includes multiple test items, which are carried out in a certain order and time interval. According to the identification results of the product to be tested, combined with historical test data and the characteristics of the product to be tested, the optimal test plan is matched;

[0063] S4: Test plan execution: Test each test item of the product to be tested in sequence according to the test process in the optimal test plan. In each test item, the test equipment detects the product to be tested according to the preset parameters, obtains the test data and performs real-time analysis to determine whether the product is qualified.

The production efficiency and product quality are significantly improved, and the production cost is reduced, which brings significant economic benefits and competitive advantages to the enterprise.

[0068] In this embodiment, the initialization configuration in S1 specifically includes:

[0069] S101: Logistics information configuration: Import the firmware version information of the product to be tested, verify whether the imported firmware version information is consistent with the version information of the actual tested product, ensure that the tested product version is correct, and prevent inaccurate test results due to version errors;

[0070] S102: Test position configuration: set no less than one test position, each test position interacts with each production line test equipment, and determines the equipment status of each production line test equipment based on the running number of each production line test equipment. The user can select software to control multiple test equipment, such as testers, sensors, etc., and intuitively display the equipment status (available or unavailable). According to the equipment status, control the availability of the corresponding button. For example, if a tester is in an occupied state, the corresponding button will be displayed in gray, indicating that it is unavailable;

The functional test list of the product is displayed according to the imported project configuration file. The user can view and select the functional test items of the new product. The user is allowed to import different configuration files to meet the test requirements of different products, thereby improving the versatility and flexibility of the software.

[0072] S104: Group test line deployment: Build software devices corresponding to each production line test equipment, establish associations between the software devices and each production line test equipment, ensure that the corresponding actual equipment can be correctly identified and controlled, and configure and manage each production line test equipment based on the associations. For example, associate the tester with the equipment in the software, and the software will automatically control the tester to perform testing, meet the test requirements, bind the actual hardware equipment, and realize automated testing.

[0073] In this embodiment, multiple test positions can be flexibly set, and test resources can be adjusted in real time according to the equipment status. For example, conflicts and misoperations of test equipment can be avoided by controlling the availability of control buttons, thereby optimizing the allocation and management of test resources and improving resource utilization. By building an association between software equipment and actual production line test equipment, automatic control and management of hardware equipment by software is achieved, greatly improving test efficiency and the degree of standardization of testing.

[0074] In this embodiment, a specific test process is constructed in S3, which specifically includes:

[0075] S301: Test plan formulation: Determine the type and test requirements of the product to be tested based on the product identification results, determine the test objectives and test standards of the product to be tested, and formulate a serial time-sharing automation production line test plan based on product characteristics, combined with historical test data and test results;

[0076] S302: Test process construction: according to the functional test items selected in the project configuration file of the product to be tested, formulate a specific test process, including at least one test item, and determine the execution order and time interval of the test items;

[0077] S303: Time segmentation: Analyze the serial communication protocol and data transmission rate of the product to be tested, including the communication rate, data packet size and transmission delay, etc., and calculate the minimum time window required for each test item based on this. These time windows are finely segmented into continuous and non-overlapping time slots to ensure that each test item can be completed within its specified time slot to avoid data conflict or loss. Based on the analysis results, the test process of the product to be tested is divided into multiple time periods to ensure data synchronization and test efficiency;

[0078] S304: Task allocation: Build a serial instruction sequence for each product to be tested in each time period, specify in detail when each test item starts, which operations are performed, and when it ends, to ensure that each step of the test process is strictly executed according to the predetermined plan, send test instructions to the corresponding product to be tested based on the serial instruction sequence, each product to be tested performs the corresponding project test, record the execution results of each test item of the product to be tested in real time, and provide real-time test data feedback;

[0079] S305: Posture adjustment: According to the requirements of the test items, the posture of the product to be tested is adjusted in real time using auxiliary mechanical mechanisms to ensure the accuracy and comprehensiveness of the test.

[0080] In this embodiment, formulating a specific test process includes the test preparation stage: environment construction: building a test environment according to the test requirements; data preparation: preparing the data and configuration files required for the test; tool preparation: selecting and configuring the tools and software required for the test; test execution stage: test case execution: executing the test case according to the test plan; defect tracking: recording, analyzing and tracking the defects found; test records: recording the test results and the problems encountered during the test; test summary stage, test report: writing a test report, summarizing the test results and the problems found; result analysis: analyzing the test results, evaluating the product quality and test coverage; experience summary: summarizing the lessons learned during the test process to provide a reference for subsequent tests.

[0081] In this embodiment, the serial communication protocol and data transmission rate of the product to be tested are analyzed in S303, specifically:

[0082] Identify the serial communication interface standards used by the product to be tested, such as RS-232, RS-422, RS-485, USB serial port, etc., and determine the communication method, data format, and control character definition of the protocol;

[0083] Send test data packets to the product under test, obtain the response time and data transmission rate of the product under test, and determine the communication performance of the product under test, including data transmission speed, stability, and error rate, so as to obtain more accurate device performance data;

[0084] Determine the baud rate range of the product to be tested according to the data transmission requirements and communication performance, test the communication quality of the product to be tested at different baud rates, and determine the baud rate of the product to be tested based on the test results;

[0085] During the test, the communication quality of the product to be tested is monitored in real time, and the baud rate is automatically adjusted according to the preset threshold to adapt to the current communication environment and device performance;

[0086] In this embodiment, in the traditional serial communication protocol, the baud rate is fixed. However, in the application scenario of production line test equipment, due to performance differences between devices and changes in the communication environment, the fixed baud rate may not meet all requirements. Therefore, the adaptive baud rate adjustment mechanism can automatically adjust the baud rate according to the communication quality and device performance to improve communication efficiency and stability.

[0087] In this embodiment, the time division further includes:

[0088] Determine the order of the test process based on the test item list and the test time requirements for each item, and determine the transmission delay time based on the communication quality of the product to be tested;

[0089] Based on the data transmission rate, the amount of data for each test item, and the transmission delay time, the minimum time window required to complete each test item is calculated to accommodate the complete data transmission and processing process while avoiding unnecessary waiting time;

[0090] Obtain a test cycle of the test process, divide the entire test cycle into multiple continuous and non-overlapping time periods, and each time period corresponds to at least one test item;

[0091] Dynamically adjust the test process according to the priority of the test items, where the length of each time period is set according to the minimum time window of the test item to ensure that each test item can be completed within its specified time period;

[0092] In this embodiment, the minimum time window required to complete each test item is accurately calculated, which effectively avoids unnecessary waiting during the test process and improves time utilization. This segmentation method ensures the orderly progress of the test process, effectively shortens the test cycle, improves test efficiency, and reduces conflicts and interference between test tasks. When product requirements or designs change, corresponding test items can be quickly added according to the changes to ensure that the functions after the changes meet expectations, thereby optimizing the test process and reducing unnecessary testing work.

[0093] In this embodiment, the dynamic adjustment test process is specifically as follows:

[0094] Record the time period division results in the test process document, including the start time, end time, test items and interdependencies of each time period;

[0095] Formulate test process adjustment rules to adjust test order, add test items, and delete test items;

[0096] Obtain the test progress of the test items in each time period, and make dynamic adjustments based on the real-time test feedback data and the established test process adjustment rules to improve test efficiency and accuracy.

[0097] In this embodiment, the rules for adjusting the test sequence include the priority principle: adjusting the sequence according to the importance and priority of the test cases, giving priority to testing key functions and core business processes; dependency: ensuring that test cases with no dependencies or fewer dependencies are tested first, and then test cases that depend on other functions; risk analysis: high-risk test cases should be tested first to detect problems as early as possible; resource availability: adjusting the test sequence according to the availability of test resources (such as test environment, data, etc.); test type: performing smoke testing and sanity testing first, and then detailed testing and regression testing.

[0098] Rules for adding test items, including requirement changes: when software requirements change, corresponding test cases should be added; defect discovery: defects discovered during the testing process may require new test cases to verify and fix; risk assessment: after new risk points are identified, test cases need to be added to cover these risks; new technology introduction: when introducing new technologies or new functions, corresponding test items should be added; customer feedback: add specific test cases based on customer feedback to meet user needs.

[0099] Rules for deleting test items, including obsolete requirements: if the requirements corresponding to the test case are no longer applicable, the test case can be deleted; duplicate tests: if there are duplicate test cases, the duplicates should be deleted to reduce unnecessary testing work; low risk / value: if the risk of the test case is low and its contribution to verifying the effectiveness of the software is small, it can be considered for deletion; resource constraints: when resources are limited, some non-critical test cases may need to be deleted; test efficiency: if the maintenance cost of a test case is much higher than the value it brings, it can be considered for deletion.

[0100] In this embodiment, based on new problems or defects discovered during the testing process, targeted test items are added in a timely manner to ensure that the problems are fully verified. When product requirements or designs change, corresponding test items are added based on the changes to ensure that the functions after the changes meet expectations. Through risk assessment, it is determined which test items are no longer critical or necessary for the current version of the product, thereby deciding whether to delete these items.

[0101] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
