Optimizing Predictive Maintenance: Enhanced AI and Backend Integration

Michael Stern, Michelle Hallmann, Francesco Vona, Ute Franke, Thomas Ostertag, Benjamin Schlueter, Jan-Niklas Voigt-Antons

TL;DR

The paper addresses the challenge of maintaining rail infrastructure and rolling stock in rural areas by proposing a low-cost wireless monitoring system based on structure-borne noise sensing and environmental data. The backend architecture combines vehicle-mounted and track-embedded sensors, $FFT$-based preprocessing, and a decentralized ledger to ensure immutability and secure data sharing, with a Docker-based processing stack and labeling interface for operators. Predictive analytics generate maintenance recommendations, which are stored back into the ledger to support traceability and governance. The paper emphasizes security, data integrity, and scalability, outlining a practical path to reliable, cost-effective Predictive Maintenance for railways and improved operation continuity.

Abstract

Rail transportation success depends on efficient maintenance to avoid delays and malfunctions, particularly in rural areas with limited resources. We propose a cost-effective wireless monitoring system that integrates sensors and machine learning to address these challenges. We developed a secure data management system, equipping train cars and rail sections with sensors to collect structural and environmental data. This data supports Predictive Maintenance by identifying potential issues before they lead to failures. Implementing this system requires a robust backend infrastructure for secure data transfer, storage, and analysis. Designed collaboratively with stakeholders, including the railroad company and project partners, our system is tailored to meet specific requirements while ensuring data integrity and security. This article discusses the reasoning behind our design choices, including the selection of sensors, data handling protocols, and Machine Learning models. We propose a system architecture for implementing the solution, covering aspects such as network topology and data processing workflows. Our approach aims to enhance the reliability and efficiency of rail transportation through advanced technological integration.

Figures (1)

  • Figure 1: The figure illustrates the integrated system for vehicle and track diagnostics, monitoring, and maintenance. Sensors on the vehicle and tracks collect raw data stored on a hard drive. The preprocessed data is sent to a decentralized ledger network via a ledger client. This network facilitates secure data sharing and analysis, covering diagnostics, alarm triggering, storage, and visualization. The analysis results and labeled data are used to maintain the vehicle and tracks, with recommendations displayed on a dashboard for associated partners and stakeholders.
