Fiber Optic Sensors in Railway IoT
This paper provides a state-of-the-art of optical fiber sensing technologies and their practical application in railway infrastructures. A smart concept for artificial intelligence contribution. To obtain the stress field distribution of the support position (bear-ing area) of the train, proposed a EMU health monitoring and intelligent state assessment system based on fiber sensing internet of things (FS-IoT). We monitor track condition, detect trespass and cable security events, and alert operators to natural hazards such as landslides or rock falls. FOS technologies enable long-distance measurements, with some systems reaching up to 100 km for distributed sensing. Our system accurately detects train movements independently from trackside equipment, locates potential issues such as track faults, track condition changes, intrusions.

What are fiber optic acoustic fingerprint sensors
Fiber optic acoustic sensors are an innovative technology that utilizes the interaction between light and sound to measure acoustic waves. This technique leverages the unique properties of optical fibers, which are capable of transmitting light over long distances with minimal loss. A metal diaphragm-based omnidirectional fiber-optic acoustic sensor with high sensitivity has been developed in this work. The acousto-optic transducer of the sensor is a single-wavelength extrinsic Fabry–Pérot interferometer (EFPI) that is highly sensitive to the displacement of the diaphragm's. Rayleigh scattering -based distributed acoustic sensing (DAS) systems use fiber optic cables to provide distributed strain sensing. This signal can then be measured by an instrument or interpreted by a user. In essence, a sensor reacts to a physical, chemical, or biological condition. In the realm of biometric recognition, fingerprint recognition has gained success with its convenient operation and fast identif ication speed. Under identical sound pressure conditions, the proposed EFPI sensor achieves a peak-to-peak output voltage of 849.
