System Architecture
The smart factory seamlessly orchestrates the integrated management of diverse energy sources, aiming to optimize operational efficiency throughout the manufacturing process. Notably, compressed air, a central component, faces potential challenges, including leaks originating from cracks or gaps within the intricate network of pipes. These instances of air leakage can significantly impact the operational efficiency of the smart factory, posing a threat to the reliability of the energy supply system. Moreover, the substantial financial repercussions, equating to a 20% loss in the factory, underscore the pressing need for effective solutions.
This paper introduces a novel unsupervised-enhanced data sampling method (UEDSM) to preserve data structure while alleviating imbalance, integrated with a dropout-enabled neural network (ALDNet) that applies Monte Carlo Dropout for robust inference. UEDSM integrates principal component analysis, k-means clustering, and cluster similarity scoring. ALDNet, a dropout-enabled neural network specially designed for air leakage detection, leverages Monte Carlo Dropout (MC Dropout) to enhance generalization and mitigate overfitting.
The effectiveness of our method is validated through a comprehensive series of experiments, incorporating real-time physical monitoring of two air compressors within a manufacturing plant. Beyond minimizing resource wastage and human intervention, our solution achieves over 95% accuracy and an F1-score above 80%, enabling reliable leakage detection several minutes in advance. UEDSM demonstrates superior efficacy when paired with ALDNet and SVM. ALDNet coupled with UEDSM achieves the highest performance, boasting an accuracy of 98.69% and an F1-score of 84.00% on the first compressor dataset, and 95.54% accuracy and 80.10% F1-score on the second.
The proposed architecture for air leakage detection incorporates three key components: air compressors capture numeric features, an edge server accommodates a customized model for early leakage detection, and an Amazon AWS cloud server is utilized for training the classification model (ALDNet) employing UEDSM. After training, models are deployed on the edge server for efficient inference, ensuring effective monitoring and timely prediction.
