摘要
催化燃烧式可燃气体探测器受环境影响局限较大,难以在船舶领域广泛应用,为此本文基于采用红外探测技术的可燃气体探测器的检测原理,对光路进行设计和优化。经验证,在双通道设计中引入双光路设计,可以同时补偿环境因素影响和放大系数的微变,大大降低在硬件电路或软件算法上进行补偿的设计难度,有效提高测量精度,在船舶应用环境中实现高精度可燃气体检测。
The catalytic combustible gas detector is greatly limited by the impact of the environment,and it is difficult to be widely used in the marine field.To solve this problem,based on the detecting principle of a combustible gas detector with infrared detection technology,the optical path was designed and optimized.The verification results show that the introduction of dual optical path design in dual channel design can simultaneously compensate for environmental factors and slight changes in amplification coefficient,greatly reduce the design difficulty of compensation in hardware circuits or software algorithms,effectively improve measurement accuracy,and achieve high-precision combustible gas detection in marine application.
