摘　　要：设计了一种基于单片机控制的光干涉瓦斯检测仪。该检测仪采用单片机AT89C2051为控制和处理核心,通过数字滤波、数值查表、线性化处理等算法,以光干涉原理和光电转换为基础实现了对煤矿瓦斯浓度的精确检测、数字化显示和超限报警,具有简单实用、可靠性强等特点。A kind of gas detector with light interference based on single-chip microcomputer was designed, which took AT89C2051 as center of control and processing. By use of arithmetics such as digital filtering, numerical value lookup, linearization processing etc. , and based on the principle of light interference and optoelectronic switching, the detector realized accurate detection for gas concentration of coal mine, digital display and overrun warning. It has characteristics of simple use, high reliability.
