通过对现有的几种隧道火灾监测技术的分析,设计出了一种基于波分复用和全同光栅技术的隧道火灾监测系统,并且将其成功运用于高速公路隧道火灾监测。实践证明,该方案是切实可行的,且测量精度较高。
Based on analyzing the existing tunnel fire alarm monitoring technology, a new type of system that employs Wavelength Division Multiplex (WDM) and the identical Fiber Bragg Grating technology was designed. The system has used successfully in highway tunnel fire monitoring. The fact demonstrates that the scheme is feasible and higher measuring accuracy can be acquired.
