Research on Vibration Monitoring Model of GNSS/Accelerometer Based on EMD
Abstract In order to obtain the dynamic response of the structure, GNSS and accelerometer are combined to monitor the vibration. We propose a hybrid filter based on empirical mode decomposition(EMD) and Chebyshev filter. We filter the data collected by GNSS to identify the high-frequency and low-frequency dynamic displacements of the structure. The high-frequency dynamic displacements are integrated with the acceleration data to reconstruct the overall dynamic displacements. Through a series of simulation data, we verify the feasibility of the reconstruction displacement algorithm.
Key words :
