摘要
针对重载铁路运行安全监测的迫切需求,提出了一种基于光纤激光传感器的重载铁路在途安全状态监测技术。在给出了光纤激光传感器基本原理与在途安全状态监测技术方案的基础上,指出了其中需要重点解决的关键技术,并给出了具体的实现方案。主要包括:高性能光纤激光振动传感器技术,高精度波长解调技术以及危险状态模式识别技术等。最后,给出了该监测技术的系统实现方案。
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 indanger status recognizing technique. The systematic schematic was also proposed.
