摘要
介绍了一个用单片机控制的甲烷浓度报警监控仪 ,能够准确地检测甲烷含量 ,当被测气体中甲烷浓度超过预定数值时 ,将声光报警 ,同时开始排风 ,可将测量结果传送 2 0 km之远。具有消除安全生产的最大隐患、电路设计新颖、参数测量准确。
The paper presents the methane concentration alarm monitor controlled by chip microprocessor,that can detect the concentration of methane correctly.When the methane concentration in tested air exceeds the rated value,the monitor will give alarm and same time start the exhaust unit,and the tested result can be sent far 20km away.The monitor can remove the most hidden peril of safety production and is characterized with new design of circuit,correct measurement parameters and convenient operation,etc.
