摘要
介绍了一种新型的光纤光栅测温系统,为了验证其在地铁区间隧道内的适用性,在合肥科大立安安全技术股份有限公司的足尺模拟地铁区间隧道内,使用93号汽油进行了模拟火灾试验。试验结果表明,在隧道纵向风的影响下,能触发传感器报警的位置发生了偏移;火源移动时,至少有2个传感器分别发生了报警,表明该型光纤光栅测温系统具有良好的响应性能。
A new fiber bragg grating temperature detection system is introduced in this paper.To verify the applicability of this system in metro tunnels,in a full-scaled simulated subway tunnel zone of Hefei Kdlian Safety Technology CO.,LTD.,fire experiments of different scales are simulated by using 93# petrol.The results show that sensor alarm points shifted with the effect of wind,and at least two sensors reacted when the combustion source was moving,which indicates that the response of the fiber bragg grating temperature detection system is quite well.
