红外多频火焰探测器工作原理 红外辐射的物理本质是热辐射,物体温度越高,辐射的红外线就越多,辐射能量也就越强。火焰光谱从紫外光、可见光到红外光都有能量辐射。碳氢化合物燃烧时在红外波段内的2.7μm与4.35μm附近有一个峰值[1],而太阳在这两个波段附近的辐射被空气中的CO2所吸收,因此使用安装窄带滤光片的中心波段在2.7μm附近的硫化铅传感器与中心波段在4. 35μm附近的热释电传感器作为火焰探测的传感器。2.7μm的硫化铅探测器对火焰信号灵敏度高,作为监测火焰强度趋势使用。在CO2峰值辐射波段4.35μm两侧各选择了一个参比波段,3.8μm与4.8μm。由于任意一个红外辐射源在这三个波段都有独自的光谱特征,因此比较这三个波段辐射强度之间的数学关系,就可将火焰和其他红外辐射源区别开来。由于红外多频火焰探测器很好地解决了传感器信号距火源距离的增加而衰减的矛盾,即各个传感器接受火焰信号辐射强度之间的数学关系不随信号的衰减而发生变化,因此结合相关检测技术对接收到的信号进行处理与分析,可以极大地提高了探测器的探测距离和灵敏度,其探测原理的先进性,保证红外多频火焰探测器抗干扰能力强,适用于室内和户外火灾探测。 |

红外多频火焰探测器工作原理 红外辐射的物理本质是热辐射,物体温度越高,辐射的红外线就越多,辐射能量也就越强。火焰光谱从紫外光、可见光到红外光都有能量辐射。碳氢化合物燃烧时在红外波段内的2.7μm与4.35μm附近有一个峰值[1],而太阳在这两个波段附近的辐射被空气中的CO2所吸收,因此使用安装窄带滤光片的中心波段在2.7μm附近的硫化铅传感器与中心波段在4. 35μm附近的热释电传感器作为火焰探测的传感器。2.7μm的硫化铅探测器对火焰信号灵敏度高,作为监测火焰强度趋势使用。在CO2峰值辐射波段4.35μm两侧各选择了一个参比波段,3.8μm与4.8μm。由于任意一个红外辐射源在这三个波段都有独自的光谱特征,因此比较这三个波段辐射强度之间的数学关系,就可将火焰和其他红外辐射源区别开来。由于红外多频火焰探测器很好地解决了传感器信号距火源距离的增加而衰减的矛盾,即各个传感器接受火焰信号辐射强度之间的数学关系不随信号的衰减而发生变化,因此结合相关检测技术对接收到的信号进行处理与分析,可以极大地提高了探测器的探测距离和灵敏度,其探测原理的先进性,保证红外多频火焰探测器抗干扰能力强,适用于室内和户外火灾探测。 |
