What was not working.
Shop-floor data is trapped in controllers, networks are intermittent and cloud-only telemetry loses the events that matter most during a stoppage.
How the system was framed.
- 01
Protocol adapters with bounded polling and timeouts
- 02
Local time-series buffer with disk quota and integrity checks
- 03
Store-and-forward publisher with duplicate suppression
- 04
Secure boot, device identity and signed OTA
- 05
Cloud ingestion, asset hierarchy and alerting
The working surface.
- Multi-protocol acquisition
- Local buffering and replay
- Device identity and signed OTA
- Store-and-forward with duplicate detection
- Asset-level alerting
Outcomes we can describe without inventing numbers.
No permanent data loss during network outages
A controlled update and rollback path
A pilot-to-fleet operations model
