광섬유 센서 — 제2-2부: 온도측정 — 분포형 센싱 光纤传感器 - 第2-2部分:温度测量 - 分布式传感
发布日期: 2018-05-02
该标准定义了光纤分布式温度传感(DTS)光纤传感器测量分布式温度的详细规格。DTS利用拉曼散射、布里渊散射、瑞利散射效果。在这里,基于拉曼散射和瑞利散射的测量仅由偏端形式的光纤组成。基于布里渊散射的测量也由偏端形式的光纤或光纤环路形式的组成。在同一时间点可以连接两端的技术[例如,Brillouin光时域分析(BOTDA,Brillouin光时域分析)]在这里被称为环路配置。光纤传感器的综合标准定义在IEC61757-1:2012。
이 표준은 광섬유 분포형 온도센싱(DTS)으로 알려진 광섬유 센서에 의한 분포형 온도 측정에 대하여 자세한 규격들을 정의한다. DTS는 라만 산란, 브릴루인 산란, 레일리 산란 효과를 이용한다. 여기서 라만 산란과 레일리 산란에 기초한 측정은 편단 형태의 광섬유 구성만으로 이루어진다. 브릴루인 산란에 기초한 측정은 편단 형태의 광섬유 또는 광섬유 루프 형태의 구성으로도 이루어진다. 동일 시점에 양 끝단에 접속 가능한 기술은 [예: 브릴루인 광 시간영역 분석(BOTDA, Brillouin optical time domain analysis)] 여기서 루프 구성이라고 불린다. 광섬유 센서에 대한 포괄적인 표준은 IEC 61757-1:2012에 정의되어 있다.
