摘　　要：针对传统红外气体分析器存在的问题,研制了一种分光型红外多组分气体分析仪。该仪器基于Lambert Beer定律,采用光学传感器阵列技术与虚拟仪器技术,同时可探测3种气体。通过更换光学滤光片组件模块和设置相应虚拟仪器软件参数,可测量SO2、CO2、CO、NO、CH4、C2H4等30多种气体。该分析仪具有成本低、维护方便、结构可靠、功能用户自定义等特点,有广阔的应用前景。Aiming at the existing problem in conventional infrared gas analyzer,a new dispersive infrared multigas analyzer was developed.On the basis of Lambert-Beer law,it adopted optical sensor array and virtual instrument technique and can monitor 3 gases at the same time.It can measure multigas such as SO_2,CO_2,CO,NO,CH_4,C_2H_4 by changing optical filter module and setting corresponding soft parameter.The analyzer has many merits such as low in price,easy in maintenance,reliable in operation and customizing function by user,so it provides a wide foreground.
