Mitsubishi Electric Equipment Integration for Ice Arena Monitoring and Control System

Reliable automation and precise environmental control are essential for modern sports facilities, especially ice arenas where temperature, humidity, and air balance must be maintained within strict limits.

This project demonstrates the implementation of a distributed monitoring and control system based on Mitsubishi Electric equipment.

Project Objectives

The system provides centralized monitoring and control of all critical engineering subsystems, including:

• Ventilation and air conditioning systems: supply and exhaust fans, fire dampers, smoke exhaust fans and valves
• Fire suppression system: push-button posts, pumps, and water supply valves
• Operator interface: centralized data acquisition, parameter configuration, and event archiving

Technical Implementation

The automation solution is based on a Mitsubishi Electric MELSEC FX3U controller with a Profibus DP master module, forming a distributed I/O system with:

• 11 remote I/O stations
• 1 logical communication station

A MAC E410 operator panel is used to display equipment status, configure parameters, and store the event archive.

Comprehensive project documentation was developed, along with PLC and HMI software. The system was fully assembled, tested, and commissioned on site.

Achieved Results

• Reduced maintenance staff requirements
• High operational convenience
• Quick detection and reporting of malfunctions or emergency events

Further Development

The same solution has since been successfully adapted for other public buildings. The project has become a standardized system design, allowing replication for new facilities with minimal adaptation and engineering effort.
