| 摘 要： | 对可燃气体(甲烷)进行有效的动态监测是火灾防控和抢险救援面临的一个重要课题。利用光纤传感技术,结合可调谐激光光谱技术、二次谐波检测的波长调制方法和光分多路技术,实现多通道分布式光纤气体检测。可避免因可燃气体(甲烷)浓度超标引发爆炸和火灾事故的发生。火灾探测新技术在一定条件下,还可以在恶劣和危险环境中为消防部队灭火救援及时提供现场气体监测信息。

| Abstract: | It is important to realize dynamic monitoring of flammable gas in fire protection and emergency rescue.This paper used the optic fiber sensing technology,the tunable diode laser absorption spectroscopy,optical multiplexing technology and the method of wavelength modulated of second harmonic to realize the multiple-channel distributed gas measurement.The fire disease caused by gas concentration over-standard can be avoided.This new detective technology can offer the real-time gas information to fire forces in dangerous environment under certain condition. |
