Hydraulic-EoL-Testing

Multivariate Time Series Data usable for Time Series Segmentation and Time Series Classification. Each sample represents the multi-phased End-of-Line-Testing cycle of one hydraulic pump (evolution of 9 sensors). For confidentality reasons, the data were normalized (standard-score) and the sensor names anonymized.

The dataset was published in the context of one of our research articles:

Gaugel, S.; Reichert, M.: PrecTime: A Deep Learning Architecture for Precise Time Series Segmentation in Industrial Manufacturing Operations, 2023


Folder Structure:

Data/
  Generation A/                Corresponding Generation. We have data from 2 generations (Generation A, Generation B)
    control type/              Coresponding pump control type. We have 3 different control types (Direct Control (DC), Proportional Control (PC), Speed-based Control (SC) )
      version/                 Coresponding version of specific control type. Only relevant for Generation A DC-pumps, where we have 3 version (V35, V36, V38)
        zip-file:              zip file containing all samples of the specific version. One Sample has the following name format:
                               "Pump_"+[Generation]+"_"+[Control Type]+[Version]+"_"+[ID]+".csv"

                           
  Generation B/                Corresponding Generation. We have data from 2 generations (Generation A, Generation B)
    control type/              Coresponding pump control type. We have 3 different control types (Direct Control (DC), Proportional Control (PC), Speed-based Control (SC) )
        zip-file:              zip file containing all samples of the specific version. One Sample has the following name format:
                               "Pump_"+[Generation]+"_"+[Control Type]+[Version]+"_"+[ID]+".csv"

Each sample contains a time-series with 11 channels (data collected at 100 Hz frequency):

  1. Time-Index (in seconds)
  2. Values of Sensors 1-9 (standard-score normalized, no units for confidentality reasons)
  3. State Label (integer-encoded, meaning not further specified for confidentality reasons)
