The application of a Brillouin distributed sensor for the monitoring of railway traffic is presented in this work. The field test is performed on the Italian regional line San Severo-Peschici, operated by Ferrovie del Gargano. A single-mode optical fiber sensor was attached along a rail length of about 60 m. The strain associated with train passage was acquired along the monitored rail length at 31 Hz acquisition rate and 1 m spatial resolution. The data acquired by the sensor demonstrates its capability of retrieving useful information in railway traffic monitoring, such as train identification, axle counting, speed detection, and dynamic load calculation.
本文介绍了布里渊分布式传感器在铁路交通监测中的应用。现场测试在由加尔加诺铁路公司运营的意大利圣塞韦罗-佩斯奇奇地区线路上进行。一根单模光纤传感器沿着约60米长的铁轨附着。在31赫兹的采集速率和1米的空间分辨率下，沿着监测的铁轨长度获取与列车通过相关的应变。传感器采集的数据证明了其在铁路交通监测中检索有用信息的能力，如列车识别、轴数计数、速度检测和动态载荷计算。
