摘　　要：甲烷易引发火灾和爆炸,可通过红外吸收式甲烷传感器进行实时检测。此类传感器的传感部分包括红外光源、热释电探测器、红外气室等部件。其中,红外气室的尺寸结构与元器件摆放位置直接影响传感器的检测精度。文章针对反射式红外气室模型,对相关元器件选型后进行建模与仿真,得到热释电探测器总接收光线率为54.3%,其中接收窗口接收光线率36%的优化结构模型。Methane,as a highly flammable and explosive gas,can be detected in real-time using infrared absorption-based methane sensors.Such a sensor comprises components including infrared light source,pyroelectric detector,and infrared gas chamber,with the latter’s dimensions and positioning of components significantly impacting detection accuracy.Focusing on a reflective infrared gas chamber model,this paper proceeded with modeling and simulation after component selection,yielding an optimized structure model where the total received light rate at the pyroelectric detector is 54.3%,with the reception window accounting for 36%of this rate.
