Embodiment Construction
[0042] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0043] figure 1 It is a schematic flow chart of a time series data anomaly detection method provided by the present invention, as shown in figure 1 The shown time series data anomaly detection method includes at least the following three steps:
[0044] Step (1): Receive the time-series data collected by one or more sensors installed in the machine and take the latest observed data in the time-series data as the data to be monitored.
[0045] In the specific implementation process, a time-series data is several observation data arranged in time order, and each observation data contains observation values of several parameters. The interval between these observations is fixed. Suppose there are m sensors in the machine, where m is a positive integer; then the time series data collected by one or more sensors in the machine is i ,p2 i ,,...pm i >, where ...
