AI Technical Summary
Existing technologies struggle to accurately identify, locate, and determine the nature of structural damage to old buildings without compromising their historical appearance and structural integrity, especially in the accurate diagnosis of early-stage microscopic damage. Furthermore, traditional methods suffer from issues of missed diagnoses and false alarms.
By combining micro-vibration and acoustic emission technologies, a closed-loop quantitative assessment and accurate confirmation of damage can be achieved through dynamic response characteristic baseline generation, instantaneous acoustic emission event signal capture, post-event response deviation measurement analysis, structural state change identifier generation, and final verification report.
It improves the accuracy and reliability of damage diagnosis, provides early warning capabilities, enables quantitative assessment of damage from its inception to its impact, avoids unnecessary excavation or destructive inspections, and is suitable for old buildings with high requirements for historical appearance.
