Abstract
A novel heavy haul train safety status monitoring technique based on the fiber laser sensors was proposed in this paper. The principles of the fiber laser sensors were introduced and the schematic of the heavy haul train safety status monitoring was given. The key technologies of the monitoring system were focused, such as the high-performance fiber laser accelerometers, the high-accuracy wavelength demodulation technique, and the in-danger status recognizing technique. The systematic chematic was also proposed.
