Rugged Local HMI Nodes for Underground Utility Tunnel Environment & Equipment Monitoring

Underground utility tunnels are the "lifelines" of modern cities, housing critical power, water, and communication infrastructure. To ensure safety and operational continuity across various fire compartments, Portworld provides specialized embedded HMI solutions—notably the YC-15EM and YC-102EB PoE Tablet. These devices serve as local monitoring nodes, providing real-time visualization of environmental data (Temperature, Humidity, Oxygen, and Hazardous Gas levels) and water accumulation alarms. Beyond monitoring, they act as localized control hubs, allowing maintenance personnel to manually operate fans, pumps, and lighting systems directly within each section of the tunnel.

High-Stability 24/7 Operation

Designed for continuous duty in isolated underground environments, with a fanless cooling system that prevents the intake of dust and moisture, extending device lifespan.

PoE Simplified Cabling (YC-102EB)
The Power over Ethernet (PoE) capability allows for efficient deployment across long tunnel sections, reducing the need for separate power outlets and simplifying the infrastructure layout.

Enhanced Environmental Protection
Equipped with an IP65-rated front panel and anti-corrosion coating to withstand the high humidity and damp conditions inherent in underground utility tunnels.


Dual Data & Control Capability

Supports multiple I/O and industrial protocols (RS485/CAN/LAN), enabling seamless connection to gas sensors and direct control of mechanical equipment like ventilation fans and sump pumps. 

High-Resolution Visual Alerts
The industrial-grade capacitive screen ensures that critical alarms—such as low oxygen or toxic gas leaks—are displayed with high clarity and immediate visual impact for field workers. 

Flexible Embedded Installation
The sleek 3mm bezel of the YC-EBT series allows for a flush-mount fit into tunnel fire-monitoring cabinets, saving space and providing a professional, integrated look.
