【摘要】 通过对火焰红外线频率的采集、分析,提出用方差和自适应滤波来判别火焰的燃烧状况的方法。首先,通过红外检测器捕获一系列在某个均值附近上下波动的火焰频率值。然后,分别运用方差和自适应滤波对采集的数据进行分析比较,找出识别火焰以及判断火焰强度的较好方法。更多还原

【Abstract】 Through gathering and analyzing of the infrared frequency of the flame,the method of judging the combustion status of flame was advanced.First,a series of flame frequency data,acquired via an infrared sensor and which fluctuate with a certain frequency around some mean value.And then,using variance and adaptive filtering methods analyze the gathering data.Finally,compared the results and found out the better method to identify whether it have flame and judge the intensity of the flame.更多还原
