Integration of UHF RFID Receptors in Railway Maintenance Systems

The paper discusses the deployment of UHF RFID receptors equipped with various sensors to enhance the maintenance of railway infrastructure. These receptors provide continuous, real-time data on safety parameters, addressing the challenge of limited revision times in subway systems. Wireless Sensor Networks (WSNs) are emphasized for their cost-effectiveness, high resolution, robustness, and low power consumption. WSNs consist of small-scale sensors capable of data processing and communication, offering advantages like self-organization, short-range broadcasting, dense deployment, and continuous topology changes. Effective management of these networks involves addressing energy consumption, data transmission, and signal processing to ensure stability and efficiency. The proposed system utilizes UHF RFID receptors, RFID tags and infrared sensors to monitor rail integrity and environmental conditions. Data is centrally processed and transmitted via GSM with GPS positioning for real-time event localization. The study examines energy consumption, distance measurement, and information transmission delays, proposing the deployment of WSNs in UHF RFID receptors to improve railway safety. Potential applications extend to civilian, military, and emergency response contexts.
