摘要
利用ARM7内核处理器LPC2129和瓦斯传感器MQ-5设计了一款嵌入式煤矿瓦斯检测仪,通过ADC通道将采集瓦斯传感器的输出电压,经过量化后显示在LCD上,当被检测到的瓦斯浓度超过预设的安全临界值时就会发出声光报警信号,提醒工作人员及时撤离并采取有效的通风措施。
Designing an embedded coal mine gas instrument by LPC2129,which captures the voltage output by gas sensor and shows it on LCD after quantizing.It gives out signal of audible and visual alarm when detected gas concentration exceeds preinstall safety value,reminding workers of leaving and adopting effective ventilation measure immediately.
