Building Engineering Systems Automation Using Mitsubishi Electric Equipment

Modern public and industrial facilities require centralized monitoring and control of all critical engineering systems to ensure safety, energy efficiency, and operational reliability. This project demonstrates a comprehensive automation solution designed to integrate ventilation, fire protection, and auxiliary systems into a unified control network.

Project Objectives

The automation system provides monitoring and control of the following equipment:

• Ventilation systems: supply and exhaust fans, pressure fans, fire dampers, and ash removal fans and valves
• Fire detection and suppression systems: sector-based fire sensors, drainage sumps, and safety monitoring devices
• Equipment status signals from elevators, heating units, and other subsystems
• Centralized data collection at the operator station with event logging and archiving

Technical Implementation

The solution is based on a distributed I/O architecture using a Mitsubishi Electric MELSEC FX3U controller
equipped with a Profibus DP master module. Two remote I/O stations are connected to handle signals
from different building sectors.

A Mitsubishi Electric GOT1000 (GT1562) operator panel provides visualization of equipment status,
parameter configuration, real-time alarms, and event history storage.

Achieved Results

• Preparation of detailed technical design documentation
• Manufacturing of control panels
• Development of PLC and HMI software
• On-site commissioning and operator training

System Benefits

The implemented solution significantly reduced the number of maintenance personnel while improving ease of operation. Real-time fault detection and alarm notification greatly enhance safety and reliability — a critical factor for facilities such as educational institutions.
