Find sensor-stuck faults in a dataframe.

Parameters:

  • df (pd.DataFrame | FlascDataFrame) -- The dataframe containing the data.

  • columns (list) -- The columns to check for sensor-stuck faults.

  • ti (Any) -- unused

  • stddev_threshold (float, optional) -- The threshold for the standard deviation of the consecutive measurements. Defaults to 0.001.

  • n_consecutive_measurements (int, optional) -- The number of consecutive measurements to compare. Defaults to 3.

  • plot_figures (bool, optional) -- Whether to plot figures for the sensor-stuck faults. Defaults to True.

  • verbose (bool, optional) -- Whether to print verbose output. Defaults to False.

  • return_by_column (bool, optional) -- Whether to return the faults by column. Defaults to False.

Returns:

The indices of the sensor-stuck faults

Return type:

np.array
