Optimizing Predictive Maintenance: Enhanced AI and Backend Integration

2025-11-20

AI Summary

To address the challenges of resource-constrained predictive maintenance and delayed fault response in rural railway infrastructure, this paper proposes and implements a low-cost, low-power wireless intelligent monitoring system. The system deploys heterogeneous sensors at critical train and track locations to form a lightweight IoT network; introduces a security- and latency-aware data transmission protocol; and adopts a distributed backend architecture enabling edge–cloud collaborative processing. Furthermore, it innovatively integrates lightweight machine learning models—including LSTM and Random Forest—for structural health assessment and early fault prediction. Experimental evaluation demonstrates a fault identification accuracy of 92.3% and a 37% reduction in operational maintenance costs. These results validate the feasibility and effectiveness of end-to-end hardware–software co-optimization for intelligent railway operations in underdeveloped regions.

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.
