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.

公路隧道风机的运行工况与健康状态数据集。
数据格式：采用空格分隔的文本文件。
数据集说明：
本数据集共包含四个子数据集。每个子数据集均由三个文件组成，文件命名格式为train_FAN_[X]P_[Y]F.txt、test_FAN_[X]P_[Y]F.txt及RUL_FAN_[X]P_[Y]F.txt。其中[X]代表运行工况点数（取值为1或4），[Y]代表潜在异常类型数（取值为1或8）。
其中，train类文件为随时间变化的剩余使用寿命（Remaining Useful Life, RUL）数据。test类文件已删除最后一条记录，因此各测试单元的剩余使用寿命均大于0；各测试单元的RUL值存储于对应的RUL_FAN_[X]P_[Y]F.txt文件中。
train_FAN_[X]P_[Y]F.txt与test_FAN_[X]P_[Y]F.txt文件均包含13列数据：第一列为设备单元编号，第二列为时间戳，第三、第四列为运行工况点，剩余八列为健康状态变量，具体包括绕组U、V、W三相温度，轴承1、2、3的温度，以及轴承1、2的振动值。
