| 摘 要： | 电容感应式冰厚检测系统每次采样的数据中,由于野值或奇异值的存在,使得冰层厚度的判断出现较大误差,为了提高判断精度,采用分段平均值法和奇异谱法的数据处理降噪方法,对冰层厚度传感器采集到的多组抽样数据进行了处理。经过对处理结果的对比分析,发现奇异谱法降噪处理后的效果更好,很好的滤除了野值和奇异值,提高了冰层厚度的判断精度。

| Abstract: | There are larger errors in identifying the ice thickness because of the outliers or singular values existing in the data sampled in the capacitive sensor system.In order to improve the identifying accuracy,we designed the method of segment mean value and the method of singular spectrum,which are used to process groups of sampled data obtained with the help of the ice thickness sensors.After a comparative analysis of the results,it is noticed that the accuracy of ice thickness identification is improved mark... |
