Singapore Mandai Depot BMS System Project

Overview 

Mandai Depot serves as an operation control center for Singapore Thomson-East Coast Subway Line and a maintenance facility for trains and buses. HollySys provides a Building Management System (BMS) divided into two parts: Rail and Bus comes with its own BMS system. Surveillance points cover the entire depot, and all data is centralized for viewing and control at the operation control center.

Solutions

HollySys supplies the LK220 redundant PLC and SCADA monitoring software, utilizing redundant fiber ring network technology to communicate surveillance points and the operation center. This provides visual displays for alarms, instrument data collection, and equipment control, creating a comfortable and effective work environment at the depot.

Results

All data is in real-time at the operation center, allowing prompt SMS notifications of any malfunctions to operations personnel, reducing the need for on-site monitoring. Furthermore, the optimization of water-cooled units enhances energy conservation and emissions reduction, thus improving the operational efficiency.
