|
摘要
针对管道泄漏问题,提出了一种基于背向喇曼散射、瑞利散射与光时域反射技术相结合的分布式光纤传感监测方法。系统由沿管线敷设的2芯单模光缆、光纤解调设备及配套软件构成,通过光纤解调设备获取感测光缆管道沿线的温度、定位数据,可实现管道泄漏的监测及快速定位。模拟实验结果表明:监测长度30 km,定位偏差小于30 m。
Aiming at leakage problem in pipelines,a distributed fiber optic sensing method was put forward based on combination of backward Raman scattering,Rayleigh scattering and optical time domain reflectometry technique. The system was made up of two-core mono mode fiber,FBG demodulator and corresponding software. Through FBG demodulator,it can obtain temperature along the pipelines as well as location data,realizing pipeline leakage monitoring and quickly locating for pipelines. Simulation experimental results show that the monitored length is 30 km,whose deviation is within 30 m.
