Condition monitoring of axial fans for road tunnels

Operating point and health data for road tunnel fans.

Format: Space separated text files.

Content:
There are four datasets in this set of files. Each dataset consists of three files named train_FAN_[X]P_[Y]F.txt, test_FAN_[X]P_[Y]F.txt and RUL_FAN_[X]P_[Y]F.txt .[X] is the number of operating points (1 or 4), [Y] is the number of possible anomalies (1 or 8). The "train" type files are time-to-end RUL data. The last records of the "test" files have been deleted, thus the RUL of each unit is higher than zero. The RUL value of each test unit is collected in the file RUL_FAN_[X]P_[Y]F.txt.

The files train_FAN_[X]P_[Y]F.txt and test_FAN_[X]P_[Y]F.txt, have 13 columns each. The first column is the unit number, the second column is the instant in time, the third and fourth columns are the operating point and the last eight columns are the health variables: temperatures in windings U, V and W, temperatures in bearings 1, 2 and 3, vibrations in bearings 1 and 2.
