[0052] Description of technical solutions
[0053] Such as figure 1 Shown is a time series-based anomaly detection method, including the following steps:
[0054] (1) Each node obtains its own detection data and enters step (2);
[0055] (2) Each node performs time correlation analysis on the local data, that is, calculates the Euclidean distance between the data in the current time window of the node and the data in the historical time window: if the calculation result is less than the given distance threshold, the data in the current time window If it satisfies the time correlation with the data in the historical time window, it is normal data, and returns to step (1); otherwise, the data in the current time window and the data in the historical time window do not satisfy the time correlation, which is abnormal data, and proceeds to step (3);
[0056] (3) Each nod...
