Artificial intelligence

The list of classes used in the ClassesV1 classification scheme as well as a short description of each of them.
  1. Alarm message

    This class represents an error in the system. A component might trigger this alarm by switching the signal from 0 to 1. Therefore, the signal is binary.

  2. Counter

    A datapoint annotated with this class is counting events. Counters usually are a monotonous signal counting events inside a component (e.g. amount of rain, cumulative energy usage). Some counters do reset at a specified maximum value.

  3. CO2 concentration

    This class denotes a sensor measuring the CO_2 concentration (usually in ppm). The CO_2 concentration is an indicator for air quality.

  4. Heat flow

    The heat flow between different circuits (e.g. within AC units) are annotated with this class.

  5. Operational message

    The datapoint labeled with this class represents messages of components. These messages can represent binary modes (e.g. on/off, or summer/winter mode) or multistate modes (modeA/modeB/modeC). These datapoints are digital.

  6. Power meter

    The current power consumption of a component is annotated with this class.

  7. Pressure

    This datapoint denotes pressure sensors (e.g. Air pressure from weather stations or pressure of liquids).

  8. Revolution counter

    Revolutions or frequencies of rotors or pumps are annotated with this class.

  9. Relative humidity

    A datapoint measuring the relative humidity in the air. The value ranges from 0 to 100 percent.

  10. Setpoint for operation

    This datapoint is a user defined set point for an operational mode. For example, a user can switch a component on or off.

  11. Setpoint in percent

    A user defined set point similar to Setpoint for operation for a percental variable (e.g. valve position).

  12. Setpoint of temperature

    This datapoint is similar to Setpoint for operation. It denotes the output of a controller for temperature. Inside offices the temperature can be regulated (within constraints) to maximize the user comfort.

  13. Setpoint of temperature offset

    This datapoint is similar to Setpoint of temperature and also annotates a user defined setpoint for temperature. However, this datapoint is regulated by a device which only allows small adjustments to the temperature in the comfortable range.

  14. Temperature of gaseous fluid

    This datapoint shows the temperature of a gas (e.g. air, …). It is usually annotated in Degree Celsius, Degree Fahrenheit or Kelvin.

  15. Temperature of liquid fluid

    This datapoint shows the temperature of a liquid (e.g. water, …). It is usually annotated in Degree Celsius, Degree Fahrenheit or Kelvin.

  16. Volume flow for gaseous fluid

    This datapoint denotes the differential flow of a gas (e.g. air inside AC units).

  17. Volume flow for liquid fluid

    This datapoint is similar to Volume flow for gaseous fluid. However, this datapoint annotates the differential flow of a liquid (e.g. water).

  18. Volatile organic compound

    Volatile organic compounds (CO_2, …) influence the air quality. This datapoint shows a combined concentration of these compounds.

  19. Valve Position

    This datapoint indicates the position of a valve. Its values ranges from 0 to 100 and show the current close/open status of the underlying valve.

  20. Electric work counter

    This datapoint describes the electrical work of a component, I.e. the cumulative electrical power over time.

  21. Working set point in percent

    This datapoint denotes a working set point (i.e. the current target of a control algorithm) for percentual measurements, e.g. valve positions). The control algorithm tries to match the actual valve position as close as possible to this working set point.

  22. Working set point for temperature

    This datapoint is similar to Working set point in percent. However, this datapoint specifies target temperatures for a control algorithm. Its unit is either Degree Celsius, Degree Fahrenheit or Kelvin.
