Application of BOTDR in Railway Fence Intrusion Detecting System

Abstract:

Article Preview

The main purpose of railway fence monitoring is to prevent people and livestock impact, cross or damage the railway fence and avoid accidents. Fiber fence technique is a new type of perimeter intrusion sensor, which was developed in the 1990s’. It has overcome many drawbacks of the traditional perimeter intrusion sensor, and realized long distance, distributed, high sensitivity, high location accuracy, low false alarm rate perimeter intrusion sensing. This article proposed a railway fence monitoring system based on BOTDR(Brillouin Optical Time Doman Reflectometer), the response time of this system is 10s, the detection range is 5km, and the location accuracy is 2m within this range.
