Description

Technical Field

[0001] This invention relates to the fields of systems engineering and integration testing technology, specifically to a complete test platform and testing method for a zero-point mapping engineering link. This invention can be applied to application scenarios requiring complete link testing, such as factory testing of zero-point mapping systems, system integration verification, and engineering link acceptance. Background Technology

[0002] The zero-point mapping engineering pipeline includes multiple stages such as zero-point positioning, zero-point locking, zero-point reconstruction, structure transfer, and fidelity verification. After each stage passes independent testing, integration testing is required across the entire pipeline to verify the overall system functionality. However, existing testing methods can only test individual subsystems and lack a complete pipeline testing platform. The existing testing scheme has the following shortcomings: (i) Lack of end-to-end testing capabilities. It is impossible to complete the entire chain of testing, from zero-point positioning to fidelity verification, on the same testing platform. (ii) Lack of an integrated testing environment. After each subsystem is tested independently, interoperability cannot be verified in a unified testing environment. (iii) The test results lack overall consistency. Passing the test for each subsystem does not mean that the entire link is working properly. (iv) Lack of end-to-end performance evaluation. The overall performance of the system cannot be evaluated at the link level. To address the above problems, this invention provides a complete test platform and test method for zero-point mapping engineering links. Summary of the Invention

(ii) This invention also provides a complete testing method for zero-point mapping engineering links, including the following steps: Step S1: The integrated control module starts the zero-point positioning test module and performs the zero-point positioning accuracy test. Step S2: After the zero-point positioning test is passed, start the zero-point locking test module and perform the locking stability test. Step S3: After the zero-point locking test is passed, start the zero-point reconstruction test module and perform the zero-point reconstruction accuracy test. Step S4: After the zero-point reconstruction test passes, start the structure transfer test module and execute the complete transfer test. Step S5: After the transmission is completed, start the fidelity verification test module and perform comprehensive fidelity verification. Step S6: The integrated control module summarizes the test results of each module and generates a full-link test report. (III) The present invention has the following beneficial effects: (1) The full-link test covers all aspects from zero-point positioning to fidelity verification. (2) The integrated control module coordinates the various test modules to ensure the consistency of test order and data processing. (3) The test report provides an overall performance evaluation. (4) Each module can run independently or in an integrated manner, flexibly adapting to different test requirements. Detailed Implementation

[0004] Example 1: End-to-end integration testing. This embodiment demonstrates the complete integration testing process of the zero-point mapping engineering link. S1. Perform zero-point positioning accuracy test. Test result: Positioning accuracy level 2. S2. Perform zero-point locking stability test. Test result: Stability level 2. S3. Perform a zero-point reconstruction test. Test results: Reconstruction success rate 99.5%. S4. Perform structural transfer test. Test results: Transfer delay ≤ 2μs, success rate 99.5%. S5. Perform fidelity verification. Test result: Overall fidelity 0.997. S6. Generate a full-link test report. Overall rating: Level 2 system. Implementation results: The end-to-end test was completed within 30 minutes, covering all 6 stages, and the test results provided a basis for system acceptance. Example 2: Fault Injection and Anomaly Recovery Test. This example demonstrates how to inject faults into a link test to verify the system's ability to recover from anomalies. S1. Zero-point positioning fault injection. External noise interference is injected during the positioning process to reduce positioning accuracy. The system is tested to see if it can relock the zero point after the interference, and the recovery time and accuracy are recorded. S2. Zero-point lockout fault injection. An environmental disturbance is injected during the locking process to test whether the lockout stability criterion can detect the disturbance and trigger correction. The response time from the disturbance to recovery is recorded. S3. Structural Transmission Fault Injection. During transmission, a portion of the data frame is intentionally truncated, and the retransmission and error control protocols are tested to see if the data can be recovered. The integrity of the recovered data is recorded. S4. Fidelity Verification. After each fault injection test is completed, a fidelity verification is performed to confirm that the system eventually recovers to a normal state after the fault injection. Implementation Results: Fault injection tests verified the robustness of the system under various abnormal scenarios. The system can detect and recover from various faults within 500μs, with an overall fidelity ≥0.99 after recovery. Example 3: Environmental boundary test. This example demonstrates performing end-to-end testing under extreme environmental conditions. S1. Temperature Boundary Test. Perform the complete zero-point positioning, locking, reconstruction, transfer, and verification process at temperatures of -40°C, +25°C, and +85°C, and record the performance indicators of each step. S2. Magnetic field boundary test. Perform full-link tests under external magnetic field environments of 0T, 0.01T, and 0.05T respectively, and record the impact of the magnetic field on zero-point positioning accuracy and locking stability. S3. Vibration Boundary Test. Perform full-link tests under no vibration, 10Hz / 5g, and 100Hz / 10g vibration environments respectively, and record the impact of vibration on locking stability and transmission success rate. S4. Boundary Determination. Based on the test results, determine the system's operating boundaries under various environmental parameters and calibrate the system's operating range. Implementation results: Environmental boundary testing determined that the system's operating range is -40°C to +85°C, magnetic field ≤0.01T, and vibration ≤10g, providing a basis for the system's environmental adaptability for deployment. Example 4: Accelerated aging and long-term stability test. This embodiment demonstrates how accelerated aging tests are used to evaluate the long-term stability of a system. S1. Accelerated aging condition settings. Based on the Arrhenius model, the accelerated aging temperature and test time are set to reduce the test time to 1 / 10. S2. Aging process monitoring. During the aging process, zero-point fingerprint detection is performed at fixed intervals (e.g., every 1 hour equivalent time), and the change in fingerprint drift rate over aging time is recorded. S3. Lifetime Prediction. Based on the drift rate trend over time, the system's operating life at normal temperatures is extrapolated and predicted. The system is considered at the end of its lifespan when the drift rate exceeds 0.5% per year. S4. Post-Aging End-to-End Testing. After accelerated aging is complete, perform a full end-to-end test to confirm the impact of aging on the performance of each component. Implementation results: The accelerated aging test prediction system has a working life of ≥10 years under normal temperature. The overall fidelity after aging is still ≥0.98. Example 5: Automated Regression Testing and Continuous Integration. This example demonstrates the application of automated regression testing in system iterative development. S1. Test Case Library Establishment. Establish an automated test case library for each stage of the end-to-end testing process, including normal test cases, boundary test cases, and abnormal test cases. S2, Continuous Integration Trigger. Regression tests are automatically triggered after each system code update or hardware change. S3. Automated Execution. The testing platform automatically executes all test cases, automatically determines pass / fail, and automatically generates regression test reports. S4. Regression Analysis. Compare the results of this regression test with the baseline test results to identify performance degradation and new defects. S5. Quality Access Control. The decision to allow changes to be merged into the main version is based on regression test results (all test cases pass and performance is not lower than the baseline). Implementation Results: Automated regression testing reduced system iteration verification time from 2 days of manual testing to 2 hours of automated testing. Quality issues in each iteration were identified and fixed before merging. Attached Figure Description
