摘要
分析了新型分布式光纤监测技术——布里渊光时域分析技术(BOTDA)的原理,提出了将BOTDA技术用于重冰区的OPGW运行及融冰过程在线监测方案,并将BOTDA技术用于OPGW线路监测中,获得各条线路的温度、应变信息,及时发现了线路的异常区域,为线路维护检修提供科学的数据。
this paper analyzes the new type of distributed fiber optic monitoring technology, brillouin optical time-domain analysis （BOTDA） principle, put forward BOTDA technology for OPGW operation of heavy ice and melt process on-line monitoring scheme, and the BOTDA technology used in three monitoring process of OPGW, acquire the information of each line temperature, strain, timely found the abnormal line area, provide scientific data for the line maintenance.
