Description

An apparatus for laying optical fiber sensor,

The present invention relates to an optical fiber sensor installation apparatus, and more particularly, to an optical fiber sensor installation apparatus in which, when an optical fiber sensor is installed on a side of a rail, an optical fiber sensor is automatically attached without manually attaching the optical fiber sensor, The present invention relates to an optical fiber sensor installation apparatus.

Generally, railway lines are constructed to reflect climate change such as temperature difference and precipitation. However, due to natural disasters caused by extreme weather and earthquakes such as heavy rains and heavy rains in the summer, cold and heavy rains in winter, It can cause a train derailment accident. Until now, the sensor was installed at a certain point and only the rail monitoring was performed at the corresponding point. However, since the vulnerable points are increasing due to the abnormal weather such as the local rainfall which is continuing recently, it is necessary to set the monitoring interval, .

Therefore, there is a technique to constantly monitor the rail by measuring strain, load, displacement, and vibration by attaching a sensor such as a strain gauge or an accelerometer to the rail. However, due to electromagnetic interference or corrosion It is difficult to monitor the whole of a specific section as a point sensor for monitoring a specific point.

Therefore, an optical fiber sensor which can be used for a long period of time without being influenced by electromagnetic waves and is small in size and easy to attach to the rail is advantageous for continuous monitoring. Particularly, the distributed optical fiber sensor system can measure the temperature and strain rate of the sensing optical fiber in thousands of points by using the characteristic change of the scattered light generated when the light incident on the sensing optical fiber passes through the optical fiber, . ≪ / RTI >

Among these scattered light, a distributed optical fiber sensor system using Brillouin scattering and Raman scattering is widely used in the market. Using the fact that the center frequency of the Brillouin scattering light changes linearly with the change in temperature or strain acting on the optical fiber among the scattered light generated when the light incident into the optical fiber passes through the optical fiber, The sensor system used for the measurement is called the optical fiber Brillouin sensor system, and the sensor system that uses the characteristic that the amplitude of Raman scattering light changes with temperature changes is called the optical fiber Raman sensor system.

Conventionally, in order to attach the sensing optical fiber to the bottom surface of the railway rail in the longitudinal direction, a rust removal operation is performed on the rail surface by using a grinder, and the optical fiber is placed on the surface of the rail and covered with epoxy tape so as to be protected from the external environment However, since the attached length is several kilometers, it takes a lot of time and labor.
