flasc.data_processing.find_sensor_faults

Module for finding sensor-stuck faults in a dataframe.

Functions

find_sensor_stuck_faults

Find sensor-stuck faults in a dataframe.

flasc.data_processing.find_sensor_faults.find_sensor_stuck_faults(df, columns, ti, stddev_threshold=0.001, n_consecutive_measurements=3, plot_figures=True, verbose=False, return_by_column=False)

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
