RAILWAY MONITORING SYSTEM
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 fib...

| description | 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 information 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 for 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.
Le système de surveillance de chemins de fer comprend une fibre optique. Une première partie de la fibre optique peut être fixée à l'une des deux voies d'un rail. Une caractéristique de la première partie de la fibre optique varie en fonction de la variabilité d'une caractéristique de ladite voie à laquelle la première partie de la fibre optique est fixée. Ce système comprend également un émetteur de signaux optiques qui est connecté à la fibre optique pour émettre un signal optique à l'intérieur de la fibre, la fibre produisant au moins un premier signal optique modifié, lequel contient des informations relatives à la variance de la caractéristique de la première partie de la fibre optique. De plus, ce système comprend un analyseur de signaux optiques qui est connecté à la fibre optique pour recevoir et analyser le premier signal optique modifié, de manière à déterminer avec certitude la variance de ladite caractéristique sur la base des informations contenues dans le premier signal optique modifié. |
