AI Technical Summary
Existing technologies struggle to achieve high-frequency, high-precision real-time monitoring of building deformation caused by dynamic loads, especially periodic and random deformations caused by wind vibration. Sensors exhibit distorted responses at measurement boundaries, resulting in unreliable monitoring data.
By acquiring historical and real-time deformation parameters and environmental wind data of the target building, a parameter linkage model is constructed. Using historical data from the lower stable region and the upper region to be corrected, the correspondence between deformation parameters at different heights is quantified. Displacement is predicted in real time at the sensor range boundary and adaptive weighted fusion is performed to eliminate data distortion.
It achieves high-precision, high-reliability and continuous monitoring of high-rise buildings under dynamic wind loads, significantly improves the availability of monitoring data under extreme conditions, and eliminates data distortion caused by sensor range boundary effects.
