分布式光纤温度传感器系统实质上是分布光纤喇曼光子传感系统(DOFTSS) ,它是近年
来发展起来的一种用于实时测量空间温度场的光纤传感系统,具有自标定、自校准和自检测功能。对光纤测温系统的基本结构和基本原理进行了说明,介绍了分布光纤喇曼光子传感系统基准值、定标和直线拟合算法的实现,通过RS232 和光纤测温系统串行通讯实现了系统状态的设置和显示,并组成了火灾预测和报警系统,对硬件结构的实现和软件流程进行了说明。
关 键 词: 分布光纤光子传感系统; 光纤测温; 标定
Abstract : Self2demarcating , self2celebration and self2checking are the functions of the optical fibre tem2 perature measuring system. The basic principle and structure of the optical fibre temperature measuring system and DOFTSS are introduced in detail . Methods of setting the benchmark value of the system , demarcating the system and realizing the baseline adjustment are also discussed. The structure of the system including parts of power supply , setting up and displaying and other controls is shown , as well as the system software flowchart . Prediction and warning system for fire hazard is set up making use of the technique of fiber temperature mea2 suring system.
Key words : DOFTSS; Optical fibre temperature measuring ; Demarcating
