- Abstract
Anomalies and noise are prevalent in the time series data extracted from sensors at construction sites, which can hinder the assessment of safety levels and risks. This study aims to detect anomalies and denoise real-time monitoring data from sensors, thereby facilitating early risk warning and enhancing accuracy of real-time status. To achieve this objective, we propose a framework that integrates Extended Isolation Forest, Whale Optimization Algorithm, and Variational Mode Decomposition models. The effectiveness of the framework is validated using a dataset obtained from sensors deployed during the construction of a deep pit foundation. The proposed approach successfully denoises the dataset without anomalies with a root mean square error of 0.0389 and signal-to-noise ratio of 24.09. Consequently, our approach effectively preprocesses data to enable improved decision-making and enhance security risk management capabilities.
