Tunnels around the world are fitted with jet fans and sensors that clear and monitor fog and smoke. They are especially important in peak hours or during emergencies such as bushfires. These jet fans can be costly to replace when they fail, so a sound maintenance program is a must to ensure longevity.
The twin Heysen Tunnels, located on the South Eastern Freeway between Adelaide and Crafers have adopted an innovative solution that leads the way in predictive maintenance.
SAGE Automation configured the SCADA and PLC components of the fan vibration monitoring system.
The system detects wear and tear before it occurs. How? Sensors installed at 12 points on each fan more accurately monitor the status of the fans and mounting brackets, via vibration trends. The system alerts users of required maintenance before damage occurs, thus increasing the life of the fans and reducing long term costs.
The vibration monitoring system is the latest innovation to be added to the tunnels. In 2000 SAGE Automation supplied and installed the control system for the Heysen tunnels.
The tunnels have 16 fan turbines and various types of sensors to monitor environmental safety and report on CO, NO, temperature and visibility levels.
Technology used: SCADA, PLCs, Communication network.
Project highlights: Smooth integration with existing SCADA System, Delivery of project under live traffic conditions, Innovative and collaborative project between SAGE and DPTI.
