摘　　要：利用单片机ATmega128L和瓦斯传感器MQ-4设计了一款便携式煤矿瓦斯探测仪,它体积小、使用方便,可随矿井工作人员随身携带。单片机获取瓦斯传感器输出的电压信号,经过模糊逻辑算法处理后能够准确判断周围环境的瓦斯浓度,并实时的显示到LCD液晶屏上。该瓦斯检测设备精度高、速度快,能有效的预警瓦斯突发事件,并且采用模糊算法处理后,大大降低了误报率,能够为煤矿的安全生产提供可靠保障。Designing a portable gas detector with MCU ATmega128L and gas sensor MQ-4,which is small size,easy to use,carried by mine staff conveniently.MCU obtains voltage signal from gas sensor,can accurately determine the gas concentration in the surrounding environment and real-time display on the LCD screen.The gas detection equipment is high precision and fast,can early warn gas outburst events effective,reduced the false alarm rate greatly by fuzzy algorithm,which provides a reliable guarantee for the safe production of coal mine.
