摘要
针对海缆重量与长度大、造价高和周期长、工程风险高、维修难度大的缺点,提出了基于布里渊散射原理的在线海缆监测系统。该系统包括数据采集硬件和信息处理软件两部分,数据采集部分用于采集与传输海缆电源谐波信息、温度信息和应变信息;信息处理软件部分用于实现信息的接收、显示和分析等数据处理功能。实验与测试结果表明,该系统能实时获取海缆的温度及应力形变信息,及时定位海缆的故障位置,达到实时监测与预警的目的。
Aiming at the characteristics of long cable length,high cost,long cycle,high engineering risk and difficultmaintenance of undersea cable,an online undersea cable monitoring system based on Brillouin scattering principle is proposed.The system is composed of two parts:data acquisition hardware and information processing software.The data acquisition part isused for collecting and transmitting the harmonic information,temperature information and strain information of the submarinecable power supply.The information processing software part is used to realize the data processing functions of data reception,display and analysis.The test results show that the system can obtain the temperature and stress deformation information of thesubmarine cable in real time,and locate the fault location of the submarine cable in time to achieve the purpose of real?timemonitoring and early warning.
