Deterministic Control & Fail-Safety.
A dedicated industrial controller governs every physical intervention, operating independently of the AI layer so that safety actions remain deterministic and reliable.
Deterministic actuation
Physical safety responses — relay switching, stack light signaling, and emergency-stop loop management — are handled entirely by a dedicated industrial control unit running on a fast, fixed scan cycle. This controller operates independently of the AI processing layer, so physical actions remain predictable and are never delayed by AI workload.
Fault tolerance by design
The AI unit sends a periodic heartbeat signal to the controller. A timer inside the controller continuously watches for that signal. If the heartbeat stops — a sign of an AI unit failure, a processing crash, or a network breakdown — the controller's watchdog function activates automatically.
- All monitored machinery relays are de-energized
- The stack light switches to a solid red fault state
- A critical system fault is logged for review
Why this guarantees safety
This design means the system only ever operates in one of two states: fully supervised by the AI decision engine, or safely halted. There is no unmonitored operating condition in between.
