This chart depicts an architecture that enables detecting various hazards, including unexpected scenarios, unexpected situations and unexpected events.
Interaction control
A
supervisor station, activates the
control station accordingly to the
situations
The architecture enables modular development of main
resilience features, painted in green in this diagram, as follows:
-
Control stations, supporting
interaction
protocols
and styles suited to the
operator's tasks.
- Control Gates, used to validate the
operator's intention in
normal (primary gate),
exceptional (
recovery gate) and
emergency (
rescue gate)
situations
- Exception handler unit, comprising a
machine control, used set the
human-machine control mode, A
trend analyzer, used to calculate the
trend data, and trigger the transition from
manual to automatic control, and the
exception detector , used to capture
exceptional situations
- An
Alarm unit,
alerting about
latent hazards, and indicating about
faults,
trends and the
grace time
- An administration station, uses an
admin gate to interface between the functional unit and the
resilience units, to enable modular testing, training and maintenance activities.
