摘　　要：对红外吸收气体检测进行了原理介绍和优点分析。从消除发光光源功率不稳定和探测器灵敏度不稳定性的因素出发 ,设计了分时差的双光源和双探测器的气室结构。采用单片机作为智能处理 ,设计了气体检测系统的原理框图 。A principle introduction and advantage analysis of the infrared absorption air detector were made in the paper. In order to eliminate the unstable power of the gleamy resources and unstable sensitivity of the detector, the time difference double gleamy resources and the air chamber structure of double detectors were designed. A microprocessor was applied for the intelligent treatment. A principle diagram of the air detecting system was designed. The hardware and software diagram of the system were designed.
