摘要
分析了隧道火灾报警领域几种常见的火灾探测技术的原理及其优缺点,包括双波长火灾探测技术、光纤喇曼散射感温火灾探测技术和光纤光栅感温火灾探测技术。后2种技术同属光纤传感技术,重点对这2种技术进行了比较,得出光纤光栅感温火灾探测技术更适合隧道火灾报警领域应用的结论。
The theory and relative merits of main existing tunnel fire detection technology are analyzed including dual wavelength fire detection technology, optical fiber Raman scattering temperature sensitive fire detection technology and optical fiber grating temperature sensitive fire detection technology. The two of later technologies, which belong to optical fiber sensing technology, are compared and the paper draws the conclusion that the optical fiber grating temperature sensitive fire detection technology is more suitable for the application to tunnel fire alarm field.
