Modern approaches to remote monitoring of rolling stock axle-box condition based on microprocessor systems

Abstract

In this article, the significance and role of axle-box monitoring systems in ensuring traffic safety in railway transport are analyzed. The types of monitoring devices currently used in the network of “Uzbekistan Railways” JSC, their condition by year of manufacture, and statistical data have been assessed to evaluate their effectiveness. Malfunctions recorded during 2022–2024, including “unidentified overheating” cases, technical failures of devices, and error signals caused by solar radiation, have been examined. Based on the obtained results, the strengths and weaknesses of the existing systems have been identified.
Furthermore, the article highlights modern approaches to remote monitoring of axle-boxes based on microprocessor systems to improve monitoring efficiency. The proposed system infrastructure employs sensitive sensors, applies filtering and intelligent algorithms for signal processing, and enables real-time data transmission via radio modules for remote monitoring. These results demonstrate that modernization of axle-box monitoring systems can enhance railway traffic safety and improve the efficiency of maintenance operations.
