Internet of things enabled rail-wheel contact temperature monitoring using fiber Bragg grating sensors

A cutting-edge method for monitoring the state of railway infrastructure is the combination of the Internet of Things (IoT) with Fiber Bragg Grating (FBG) sensors for railway health monitoring. Rail wheel contact temperature monitoring relies heavily on precise and timely parameter sensing because these components are subject to a wide range of situations. Sensors using Fiber Bragg Gratings (FBGs) can be used for this purpose. The FBG sensor is highly desired since it is resistant to electromagnetic radiation. The Internet of Things (IoT) and FBG sensors are the main components that make online real-time sensing possible. We have constructed an experimental setup with a 1:5 downscaled model FBG placed at the rail wheel contact in order to successfully forecast the temperature in the rail wheel contact. The temperature was ascertained by utilizing the variation in the Bragg grating wavelength via the FBG interrogator. The gateway, which allows for long-distance temperature readings in real time, was linked to the interrogator. An illustration of the experimental setup is given in the document. As the test rig frequency increased from 10 to 40 Hz, the sensor's wavelength shifted from 1538.7603 to 1538.863 nm, indicating a significant temperature rise. A comprehensive monitoring system that improves the safety, effectiveness, and financial sustainability of railway operations is produced by the combination of IoT and FBG sensors. The implementation of this technology has the potential to revolutionize the railway industry by reducing maintenance costs, enhancing safety, and eliminating downtime.
