可燃气体报警器检定中，涉及的气体具有危险性，设计可燃气体检定罩通风报警装置，实验用溢出的可燃气体，经过气体浓度传感器检测后的信号进行A／D转换及处理，通过LCD实时显示检定过程中排放的可燃气体浓度值，并与设定的浓度上限值进行比较，当超过该浓度值时，启动通风装置以使室内的可燃气体浓度得到及时调节。

Because of the danger in the test of the inflammable gas, we design the ventilation alarm set for the casing of the flammable gas test. The signal of the overflowing flammable gas for the test which tested by the gas density sensor set is witched into A/D and passed into the SCM. The density of the flammable gas vomited during the test is displaying on the LCD, which compared with the settled maximum of the density, when the density surpass the maximum, the ventilation set is switched on and the density of the flammable gas is regulated in time.
