| 摘 要： | 提出了一种基于变长扫描模型的故障检测方法.该方法对待检测的时间序列数据进行差减操作求得相应的差减序列,由于跳跃点会影响两个相邻差减序列的统计特性,因此通过当前差减序列来估计即将来临的下一时刻的取值区间,进而判断下一时刻是否足跳跃点,从而实现故障检测,考虑算法的时间复杂度,设计了扫描窗口的变长机制,以在检测精度和检测速度... |

| Abstract: | A fault detection method based on varying-length scanning model is proposed.This method performs minus-operation on the time series data to be detected and then gets the corresponding difference minus sequence.The statistic characters of two neighboring difference minus sequences are affected due to the change point,so the proposed method estimates the value interval at next time through current difference minus sequence,and then realizes fault detection by estimating whether the change point exists at next... |
