摘要
针对光纤光栅隧道火灾报警系统,研究了光纤光栅温度传感网络的原理与存在的问题,在此基础上,设计出了一种新型波长可调谐半导体激光器,提高了光纤光栅温度传感网络的检测范围和空间分辨力,进而改进隧道火灾报警系统,使光纤光栅隧道火灾报警系统更好的为公路隧道的安全运营服务。
In view of the FBG tunnel fire alarm system,this paper studies the principle of Fiber Bragg Grating temperature sensing network and the existing problems. So we design a new type of wavelength tunable semiconductor laser,increasing the Fiber Bragg Grating temperature measuring range and spatial resolution. This study can increase a single Fiber Bragg Grating temperature sensing network detection range and spatial resolution. The study in this paper can be better for the safety of highway tunnel operation.
