Title:
PASSIVE EXCITATION-BASED ONLINE CALIBRATION METHOD FOR BRIDGE STRUCTURE STRAIN MONITORING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/267613
Kind Code:
A1
Abstract:
A passive excitation-based online calibration method for a bridge structure strain monitoring system, comprising: taking a dynamic load of a normal passing vehicle of a bridge as a passive excitation source to act on a bridge structure; an RS system and an SMS system to be calibrated continuously and synchronously acquiring strain data of the bridge structure, and forming measurement data sequences according to time sequencing; calculating an instantaneous measurement error, a period measurement error, and a basic error of the SMS system according to the measurement data sequences respectively acquired by the RS system and the SMS system to be calibrated; and taking the instantaneous measurement error, and/or the period measurement error, and/or the basic error as a calibration basis to perform online calibration on the metrology performance of the SMS system.
