AI Technical Summary
In the non-destructive testing of fatigue characteristics of long-life pavement materials, the direct superposition of response information from multiple types of sensor data in existing technologies leads to unstable fatigue assessment results, making it difficult to form a continuous and interpretable fatigue evolution trajectory and affecting the reliability of the assessment results.
By constructing a continuous and consistent time-stamped acquisition chain and time-stamped consensus band, a dominance switching prompt frame is generated. The detection data is rearranged according to the weighted traction list, and an anti-time-series breathing phase-locking method is introduced to regulate the output rhythm of the detection data, thereby eliminating fatigue state jumps caused by dominance switching.
It enables precise labeling and dynamic perception of the moment when signal dominance is switched, improves the continuity and interpretability of fatigue assessment results, and enhances the tracking stability and response accuracy of the monitoring system for complex fatigue behaviors.
