Railway infrastructures have played a critical role to ensure the continuity of goods and passenger transportation in China. Under extreme
Using a combination of Rayleigh backscatter and time of flight, Praetorian fiber optic sensing for railways determines the presence, location, intensity, and frequency of vibrations along an optical fiber in real
The geometrical rail track condition is monitored in real-time using fiber optic sensors, providing early warning if pre-defined thresholds are exceeded in terms of longitudinal, horizontal and
This paper offers a new method of applying statistical modelling and machine learning to enhance the interpretation of fibre optic sensing data, and, therefore, improve deterioration
This is why the railway industry is increasingly turning to distributed optical fiber sensing as a foundation for next-generation monitoring and early
Fiber optic-based monitoring systems use quasi-distributed and continuously distributed sensing techniques for real time measurement and long term assessment of structural properties.
Abstract The importance of railway safety cannot be overemphasized; hence it requires reliable traffic monitoring systems.
Several rounds of calibration led to an improved early warning of a wheel defect but further improvement is needed. The experience brought operational teams and
FOTAS can operate independently, but when necessary, it can integrate with SCADA, BMS, or maintenance systems, transforming early
High-speed railway has achieved remarkable development in China, and safety monitoring of high-speed railway is becoming an important research. Fiber bragg grating (FBG) sensing technology is
