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 sub-millisecond polling, bounded jitter, and a topology that survives a single-node failure without blinding the segment.

What it does

• Polls all cells in its segment at fixed sub-millisecond cadence.
• Runs first-stage modality fusion and per-cell baseline drift detection.
• Maintains a fail-safe local store of the last N minutes of telemetry independent of the uplink.
• Issues tiered alerts according to a documented escalation policy.
• Holds dual-path redundancy so a single physical break does not silence a segment.

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.
