针对储油罐内温度分布信息掌握不足的隐患, 介绍了一种以光频域反射(OFDR)为基本原理设计而成的分布式光纤测温预警系统, 该系统主要由测温光缆、光纤测温主机和火灾报警主机组成, 并设计了基于储油罐的光纤测温预警系统方案, 描述了系统实施的主要工作。分布式光纤测温预警系统稳定可靠, 性能指标高, 可提供详细的空间温度分布信息, 对储油罐火灾的预防以及灭火具有很大的帮助。

According to the deficiency of temperature distribution in tanks, a distributed optical fiber temperature measurement and early-warning system based on optical frequency domain reflectometer (OFDR) principle is introduced. The system is consisted of temperature measurement optical fiber, optical fiber temperature measurement main equipment and fire alarm main equipment. The scheme of optical fiber temperature measurement and early-warning based on tanks is designed, and main works for system implementation is described. The system has a good reliability and performance index, which can provide detailed space temperature distribution information and helps a lot in fire prevention and extinguishing.
