车载式甲烷报警断电检测仪设计

Design of Warning and Power-off Device for Vehicular Methane Detector

为了实时检测煤矿井下空气中甲烷的体积分数,利用ATmega16L单片机设计了一种低功耗车载式甲烷报警断电检测仪.该检测仪主要用于煤矿井下的电机车.当空气中甲烷的体积分数超出警戒值时检测仪发出声光报警信号,同时切断电机车的供电电源.测试结果表明,该检测仪的测量精度达到国家标准。

In order to detect the density of methane in the mine, a low power vehicular methane detector for warning and power-off based on ATmega16L is designed. The detector is mainly installed on the locomotive in the mine. When the density of methane in the mine exceeds a specified value, the detector would send out the acoustic-optic warning signal and the power is cut off. Experiments show that the measuring precision of the detector is accord with the national standard.
