Smart Container Door Alert System
Design and simulation of a hybrid connectivity solution for maritime logistics security, addressing the critical "Blackout Zones" in global shipping.
University of Aberdeen
Supply Chain Management (QB59H1)
The Challenge
Global maritime logistics faces a critical vulnerability: "Blackout Zones." When vessels move beyond coastal cellular coverage (approx. 5 miles offshore), real-time visibility is lost.
Key Risks
- Unnoticed Cargo Theft
- Door Tampering
- Temperature Spoilage
The Solution: Hybrid Connectivity
Deploying lightweight, battery-efficient sensors (DS18B20) to monitor temperature, humidity, motion, and door status in real-time.
Combining LoRaWAN for onboard mesh networking with burst-satellite technology to transmit critical alerts even from the middle of the ocean.
Simulation Results
Data from the prototype simulation demonstrating the system's effectiveness in monitoring critical environmental parameters.
Range: 0.14°C - 10.78°C
Max: 106.9% (Alert Triggered)

Key Findings
Enhanced Security
The system successfully detected 100% of simulated door opening events, providing immediate alerts.
Environmental Control
Continuous monitoring of temperature and humidity allows for proactive intervention before cargo spoilage occurs.
Energy Efficiency
The hybrid communication model proved to be energy-efficient, maintaining battery levels above 98% over the simulation period.
