Station Beam Health Rules

A file to store health transition rules for station.

class StationBeamHealthRules(*args: Any, **kwargs: Any)[source]

A class to handle transition rules for station.

property default_thresholds: dict[str, float]

Get the default thresholds for this device.

Returns:

the default thresholds

degraded_rule(beam_locked: bool, station_fault: bool, station_health: ska_control_model.HealthState, antenna_healths: dict[str, Optional[ska_control_model.HealthState]]) → tuple[bool, str][source]

Test whether DEGRADED is valid for the station.

Parameters:

  • beam_locked – if the beam is locked.

  • station_fault – If the station is in fault state.

  • station_health – Health of the station.

  • antenna_healths – Health of the antennas.

Returns:

If the station beam is degraded or not.

failed_rule(beam_locked: bool, station_fault: bool, station_health: ska_control_model.HealthState, antenna_healths: dict[str, Optional[ska_control_model.HealthState]]) → tuple[bool, str][source]

Test whether FAILED is valid for the station beam.

Parameters:

  • beam_locked – if the beam is locked.

  • station_fault – If the station is in fault state.

  • station_health – Health of the station.

  • antenna_healths – Health of the antennas.

Returns:

If the station beam is failed or not.

healthy_rule(beam_locked: bool, station_fault: bool, station_health: ska_control_model.HealthState, antenna_healths: dict[str, Optional[ska_control_model.HealthState]]) → tuple[bool, str][source]

Test whether OK is valid for the station.

Parameters:

  • beam_locked – if the beam is locked.

  • station_fault – If the station is in fault state.

  • station_health – Health of the station.

  • antenna_healths – Health of the antennas.

Returns:

If the station beam is healthy or not.

unknown_rule(beam_locked: bool, station_fault: bool, station_health: ska_control_model.HealthState, antenna_healths: dict[str, Optional[ska_control_model.HealthState]]) → tuple[bool, str][source]

Test whether UNKNOWN is valid for the station beam.

Parameters:

  • beam_locked – if the beam is locked.

  • station_fault – If the station is in fault state.

  • station_health – Health of the station.

  • antenna_healths – Health of the antennas.

Returns:

If the station beam is in unknown state.
