一种CO、CO2、SO2三组分红外集成气体传感器
摘要：
本发明涉及一种CO、CO2、SO2三组分红外集成气体传感器，包括外壳、红外光源、进气口、出气口、气室、三组带不同特定波长滤光片的测量红外探测器和带不同特定波长滤光片的参比红外探测器的集成探测器、信号放大处理器、温度传感器、单片机系统、声光报警系统。这种气体传感器利用CO、CO2、SO2气体分子对红外光的选择性吸收实现对CO、CO2、SO2三种气体的同时监测和检测，能在恶劣环境中长期稳定并可靠运行，具有较好的抗干扰性，其结构简单，操作方便，能同时对三种气体进行检测并储存数据，在大大降低加工成本的同时进一步提高了检测精度。
摘要（英）：

The invention relates to a CO, CO2 and SO2 three-component infrared integrated gas sensor which comprises a shell, an infrared light source, a gas inlet, a gas outlet, a gas chamber, three groups of integrated detectors consisting of infrared measuring detectors with different particular wavelength light filters and infrared reference detectors with different particular wavelength light filters, a signal amplification processor, a temperature sensor, a singlechip system and an audible and visual alarm system. The gas sensor can be used for monitoring and detecting three gases such as CO, CO2 and SO2 simultaneously by utilizing selective absorption of CO, CO2 and SO2 gas molecules on infrared light, can stably and reliably operate in a severe environment for a long time, has high interference resistance, is simple in structure and convenient to operate and is capable of simultaneously detecting the three gases and storing data, and the processing cost is greatly reduced while the detection precision is further improved.
