【摘要】 介绍了一种海底管道健康监测系统,该系统利用分布式光纤传感技术对海底管道应变进行实时监测,采用波分复用技术以光纤传感器串联形式来解决单个传感器监测距离短的缺点,实现长距离海底管道健康监测,系统具有预警功能,能够在海底管道面临危险时发出警报,确保海底管道安全运行。系统不仅可以用于海底管道,还可以用于陆上管道、桥梁、大坝等结构物的健康监测,具有广阔的应用前景。更多还原

【Abstract】 A kind of health monitodng system for submarine pipeline is introduced in the paper,distributed optical fibersensing technology is used to monitor the strain of submarine pipeline for real time,and wavelength division multiplexing(WDM)technology is used to solve the problem of monitoring for long distance submarine pipeline in this system.It cm alarm when submarine pipeline is faced with danger,and ensure submarine pipeline safbty.This systemcm be used to monitor not only submarine pipeline but also structures such as pipeline in land,bridge,dm et al,andhas a wide application prospect.更多还原
