摘　　要：本文详细介绍了如何根据气体传感器的气体特性数据来计算混合气浓度特性的方法。并以TGS822TF型传感器为例,详细介绍了以氢气设定、以CO浓度规定报警点的人工煤制气报警器设定浓度的计算方法。通过使用EXCEL对H2和CO的气体浓度特性数据进行处理,根据不同地区的人工煤制气的组分含量,即可计算当地煤制气报警器的设定浓度。It is introduced in detail in this paper how to calculate the mixture gas concentration according to the gas characteristic parameters of gas sensors. Furthermore, taking TGS822TF sensor as an example, a calculation method for manual concentration setting of coal gas is introduced in detail by putting hydrogen as the calibration gas and the concentration of carbon monoxide as the alarm point. After the concentration characteristic data of hydrogen and the carbon monoxide gas.are carried out with EXCEL, the alarm setting concentration of the coal gas detector for different cities can be calculated according to the different components of the local coal gases.
