By using correlation analysis, we are able to calculate the self correlation coefficient of the same characteristic value to achieve the association of current and previous one and the cross correlation coefficient of two different characteristic values, consequently achieve the data association between characteristic values. 3. On the characteristic level, we are trying to fuse the characteristic values from different data source and identify the exact type of the fault.

用同种类多个传感器进行测量，得到的数据以加权自适应估计方法将它们融合处理得出最佳值；对来自异类多个传感器的数据进行最小二乘估计处理将它们融合到一起，完成数据关联和从测量数据估计出它们所反映的特性；通过计算征兆数据的自相关系数能完成同一征兆当前值与过去值的关联，又可以通过计算两个征兆数据的互相关系数完成这两个征兆的关联。
