Multisensor data fusion-based structural health monitoring for buried metallic pipelines under complicated stress states

نویسندگان

چکیده

During long-term service, buried pipelines are subjected to complex combined loads, including internal and external loads pipe–soil interactions. In this paper, a multisensor monitoring network is proposed for the structural health (SHM) performance assessment of metallic in complicated stress state. However, general, longitudinal bending axial thermal cannot be directly obtained by separately considering each information source (i.e. measured strain temperature differentials). Therefore, Bayesian fusion-based estimation method states physics-based data fusion calculating stresses presented. A field application with construction operation phases was carried out investigate efficiency scheme method. The results illustrated that successfully estimated calculated stress. distribution equivalent obtained, pipeline evaluated. Notably, showed significant caused overburden uneven pipe trenches foundation settlements during phase, which not considered classical calculation models current design codes. This practical project provides strong evidence motivation paper.

A New Method for Multisensor Data Fusion Based on Wavelet Transform in a Chemical Plant

This paper presents a new multi-sensor data fusion method based on the combination of wavelet transform (WT) and extended Kalman filter (EKF). Input data are first filtered by a wavelet transform via Daubechies wavelet “db4” functions and the filtered data are then fused based on variance weights in terms of minimum mean square error. The fused data are finally treated by extended Kalman filter...
