PROJECT TOPICAdvanced Manufacturing & Industrial IoT
Multi-Protocol Gateways
An embedded systems concept designing an edge translator hardware module that polls disparate factory bus networks and maps telemetry onto uniform JSON/MQTT streams.
Brownfield Factory Telemetry Harmonization
- ✓Bridges isolated legacy serial fieldbuses with modern Ethernet infrastructure.
- ✓Implements hardware isolation (opto-couplers) for robust industrial electrical noise immunity.
- ✓Enables predictive analytics without replacing operational legacy PLCs.
The Engineering Challenge
Problem / Objective
Brownfield manufacturing facilities feature mixed legacy machines speaking conflicting hardware protocols, preventing unified floor visibility.
