基于ARMv7-M架构的矿用多参数气体检测仪的设计

Design of Mine-used Multiple Parameters Gas Detector Based on ARMv7-M Architecture

针对目前矿用气体检测仪只能检测单一气体并且测量气体浓度范围较窄等问题,设计了基于ARMv7-M架构的矿用多参数气体检测仪。此多参数气体检测仪采用STM32处理器以及内外自动切换功能的电源供电模式,将采集到的甲烷、二氧化碳、氧气、一氧化碳的浓度以及环境温度和电源电压值进行数据处理并发送到液晶显示器进行显示。当气体浓度超限或电源电压欠压时检测仪声光报警。经实验测试结果表明该多参数气体检测仪具有自校准功能、精度高、检测范围广、稳定性好、响应速度快和抗干扰能力强等优良性能。

In view of the present mine gas detector can only detect single gas and the measurement range of gas concentration is relatively narrow,the design of mine multi-parameter gas detector based on ARMv7-M architecture was presented.The detector was built based on STM32 processor, with automatic switchover power supply mode.It collected the concentration of methane, car- bon dioxide, oxygen and carbon monoxide, environment temperature and supply voltage values for data processing and display.When the gas concentration overran or the supply was undervohage ,the detector rang the sound ＆ light alarm.Test results show that the multiple parameters gas detector has self-calibration function, high precision, wide range of detection, good stability, fast response speed and strong anti-jamming capability.
