Abstract

This research presents a novel approach to pipeline Structure Health Monitoring (SHM) by utilizing frequency response function signals and integrating advanced data-driven techniques to detect and evaluate vibration responses regarding loose bolts, scale deposits within pipelines, and cracks at pipeline supports, aiming to determine the effectiveness of utilizing artificial neural networks (ANN) and an ensemble learning approach in detecting the aforementioned damages through a data-driven approach. The research starts by recording 6500 samples captured by two accelerometers, related to 11 replicated pipeline structural scenarios. The research demonstrated the potential of principal component analysis (PCA) in dimensionality reduction, achieving approximately 81% reduction in data set 1 acquired by accelerometer 1 and around 79.5% in data set 2 acquired by accelerometer 2, without significant loss of information. Additionally, two ANN base models were employed for fault recognition and classification, achieving over 99.88% accuracy and mean squared error values ranging from 0.00006 to 0.00019. A significant innovation of this work lies in the implementation of an ensemble learning approach, which integrates the strengths of the base models, showcasing outstanding performance that was proved consistent across multiple iterations, effectively mitigating the weaknesses of the base models and providing a reliable fault classification and prediction system. This research underscores the effectiveness of combining PCA, ANN, k-fold cross-validation, and ensemble learning techniques in pipeline SHM for improved reliability and safety. The findings highlight the potential for broader applications of this methodology in real-world scenarios, addressing urgent challenges faced by infrastructure owners and operators.

通过堆叠集成学习和数据融合保护管道完整性
本研究提出了一种管道结构健康监测(SHM)的新方法,该方法利用频响函数信号和集成先进的数据驱动技术来检测和评估有关螺栓松动、管道内结垢和管道支架裂缝的振动响应。旨在确定利用人工神经网络(ANN)和集成学习方法通过数据驱动方法检测上述损害的有效性。该研究首先记录了两个加速度计捕获的6500个样本,涉及11个复制的管道结构场景。研究证明了主成分分析(PCA)在降维方面的潜力,在没有显著信息损失的情况下,加速度计1获取的数据集1实现了约81%的降维,加速度计2获取的数据集2实现了约79.5%的降维。采用两种神经网络基础模型进行故障识别和分类,准确率达到99.88%以上,均方误差在0.00006 ~ 0.00019之间。这项工作的一个重要创新在于集成学习方法的实现,该方法集成了基本模型的优点,展示了在多次迭代中被证明一致的出色性能,有效地减轻了基本模型的弱点,并提供了可靠的故障分类和预测系统。本研究强调了在管道SHM中结合PCA、ANN、k-fold交叉验证和集成学习技术以提高可靠性和安全性的有效性。研究结果强调了该方法在现实场景中更广泛应用的潜力,解决了基础设施所有者和运营商面临的紧迫挑战。
