Abstract: A railway monitoring system firstly includes an optical fiber. A first part of the fiber is attachable to one of a pair of tracks of a rail, and a characteristic of the first part of the fiber is variable in correspondence to variance of a characteristic of said one track where the first part of fiber is attached. The system also includes an optical signal emitter connected to the fiber for emitting an optical signal into the fiber, and the fiber generates at least a first altered optical signal, which contains informatio n relating to the variance of the characteristic of the part of the fiber. The system further includes an optical signal analyzer connected to the fiber fo r receiving and analyzing the first altered optical signal so as to ascertain the variance of said characteristic of said one track based upon the information contained in the first altered optical signal.
一种首先包括光纤的铁路监控系统。该光纤的第一部分被附着在铁路的一对轨道之一上,且对应于光纤第一部分附着的所述一轨道的特性的变化,该光纤第一部分的特性是可变化的。该系统还包括连接到光纤的光信号发射器,用于向光纤发射光信号,并且该光纤产生至少第一变更的光信号,其包含与光纤部分的特性的变化相关的信息。该系统进一步包括连接到光纤的光信号分析器,用于接收和分析第一变更的光信号,以至于基于在第一变更光信号中包含的信息来确定所述一轨道的所述特性的变化。
