摘　　要：针对煤矿井下安全生产的需要,设计了一种瓦斯和氧气两种气体浓度同时进行监测的系统。该系统由气敏传感器、模数转换、单片机控制器、显示器和报警器等电路组成。系统以低能耗、低电压供电的AT87LV51为处理器,以MQ-9和TiO_2气敏电阻为探头,配以高亮度的LED显示器,具有高精度、高亮度、高可靠性,具有可嵌入在其他电气设备中使用的特点。According to the need of safety production in coal mine, designs a monitoring system of gas and oxygen concentration. This system consists of gas sensors, analog to digital converters, a mierocontroller unit, displays and alarm circuits. Utilize the MQ-9 and the TiO2 gas sensitive resistor for gas sensor, utilize low power consumption AT87LV51 for microcontroller, utilize the high brightness LED for display. It has the advantage of high precision, high brightness and high reliability. It can be embedded in other electrical equipment.
