Segment Master

The Segment Master is the industrial fieldbus controller that aggregates cell telemetry, runs first-stage anomaly logic, and forwards events to the vessel gateway. One segment master serves a bounded population of sensor cells; multiple masters serve a deck; multiple decks serve a vessel.

Why a deterministic fieldbus

Detection latency is the entire product. A best-effort IP network is not adequate for time-bounded delivery of alerts on a moving steel platform with electromagnetic noise from machinery, comms, and navigation systems. EtherCAT-class deterministic networking gives us time-bounded polling, bounded jitter, and a redundant path designed so that coverage degrades gracefully rather than going dark.

What it does

• Polls the cells in its segment on a fixed, deterministic cycle.
• Runs first-stage modality fusion and per-cell baseline drift detection.
• Maintains a fail-safe local store of recent telemetry independent of the uplink.
• Issues tiered alerts according to a documented escalation policy.
• Carries redundant paths so that segment coverage is not dependent on a single link.

Operational envelope

Integration

The segment master speaks to upstream systems over a documented event and telemetry interface and is designed to integrate with existing bridge consoles and shore-side IT without architectural change to the host vessel's networks.
