摘要
分析了特殊行业对火灾报警的要求,介绍了光纤光栅感温技术原理、隧道火灾点火实验以及技术应用的情况。实验和应用结果表明,光纤光栅火灾报警系统能够准确及时地进行火灾报警,并能实时测量出火灾地点的温度分布,是一种具有广阔应用前景的火灾探测新技术。
The demand for fire alarm applications on some special fields is presented. And the theory of fiber bragg grating sensing is also introduced. The fire experiments in tunnels and some applications have been carried out. The results show that the new fire alarm system can be used to alarm fire exactly and duly. In addition, the temperature distribution at the fire location can be measured synchronously. The obtained results showed that the technique may be imposed as an available great application for fire alarm.
