MONITORING SYSTEM AND METHOD FOR CONCRETEBALLAST

摘要

PURPOSE: A system and a method using an optical fiber brillouin scattering sensor for monitoring the deformation of railway concrete roadbed are provided to sense a position and the size of the deformation generated in an arbitrary position on the railway concrete roadbed of a monitoring target section, thereby measuring the deformation of a track caused by a roadbed loss and subsidence might be generated natural disasters. CONSTITUTION: A system using an optical fiber brillouin scattering sensor for monitoring the deformation of railway concrete roadbed comprises a roadbed monitoring member and an information analyzing member. The roadbed monitoring member acquires brillouin scattering lights according to the length of an optical fiber buried in the concrete roadbed, thereby calculating a brillouin frequency, which is a frequency of the brillouin scattering lights. The information analyzing member converts the brillouin frequency acquired by the roadbed monitoring member, thereby extracting the temperature of the roadbed and deformation data thereof.
