介绍了地铁隧道及地铁其它区域的分布式光纤感温火灾探测系统和光纤光栅感温火灾探测系统的设置方案、各自特点,讨论了分布式光纤感温火灾探测系统中分布式感温光纤和光纤光栅感温火灾探测系统中光纤光栅感温探头的安装要点以及系统组网形式。实际应用证明,分布式光纤感温火灾探测系统和光纤光栅感温火灾探测系统凭借各自较好的特性已成为传统感温火灾自动报警系统的有力补充,预计两者在轨道交通领域的应用将会越来越广。 This paper introduces the configuration scheme of distributed optical fiber temperature sensing fire detection system and fiber grating temperature sensing fire detection system in metro tunnels and other areas of metro and their respective characteristics. The distributed temperature sensing optical fiber and optical fiber in distributed optical fiber temperature sensing fire detection system are discussed. Grating temperature sensing system fire FBG temperature probe installation points and system networking forms. Practical application shows that the distributed optical fiber temperature sensing fire detection system and the FBG temperature sensing fire detection system have become the powerful complement to the traditional thermal sensing fire alarm system by virtue of their respective good characteristics. It is expected that the application of the two in the field of rail transit will More and more widely.
