Scenario
Deployment of community-based smart parcel lockers for secure and efficient package drop-off and retrieval.
System Configuration
X-DI Module (for detecting door open/close status)
X-RS232 Module (for interfacing with the touchscreen panel)
Implementation
The X-DI module continuously scans all locker compartments for open/closed status using dry or wet contact signals (normally open/normally closed).
The X-RS232 module communicates with a local touchscreen via a custom protocol, enabling user interface functions such as pickup code input and real-time status display.
The OpenPLC program manages the core locker logic—assigning compartments, controlling door latches, and handling exceptions.
A 4G module connects the locker system to the cloud for real-time data sync, enabling backend logistics coordination and user app integration.
Advantages
Remote fault reset: Maintenance staff can remotely reset individual locker compartments if a fault is detected.
Flexible input compatibility: The X-DI board supports both dry and wet contact signals, allowing seamless integration with a variety of door switch types.
Reliable connectivity: With built-in 4G support, the system stays online for remote diagnostics and management.
Conclusion
This solution demonstrates how ARMxy hardware combined with OpenPLC provides a cost-effective and reliable platform for smart locker systems—scalable for both residential and commercial deployment.
