Because of safety concerns and several fire accidents, the management of Taichung Power Plant finally decided to equip its system of conveyor belts with a fire detection system to monitor the temperature along the belts and in case of fire send alarms in order to minimise the damages.
So it requires for quick fire detection and precise localization of the fire source and in the meantime, as the fire source could move with the operation of the conveyor, it would be even harder to monitor the belts.
But LIOS DE.TECT system can fulfils all the requirements of this project:
1.The system should provide long range distributed fire detection
2.Even the fire source could be moving, the system can still provide quick fire detection
3.The system can operate normally in the harsh conditions and is maintenance free
LIOS has supplied its DE.TECT system for Taichung Power Plant which covers the whole conveyor system. There are altogether four conveyor belts monitored, two from the harbour to the transfer tower and two from the transfer tower to the generation units.
The fibre optic sensing cable is easy to install and has a long measurement range. As it is purely passive sensor, it doesn't need any maintenance after installation and wouldn't be affected by the harsh operating environment, which makes it very suitable for the conveyor belts monitoring.
The DE.TECT controller is installed in the control room in the transfer tower – in the middle of the whole conveyor system – so that it is more convenient and economic to measure towards both sides. Furthermore, as located in an endangered area, an extra cabinet which fulfils the standard of IP-66 is also installed.
The measurement data and derived alarm information are transmitted via TCP/IP via MODBUS protocol to the management system of the operator and the visualisation unit in the control room.
The customer especially appreciates the highly endurable design of the DE.TECT evaluation unit which is ideal for deployments in harsh environments. It comes with a completely encapsulated housing and doesn’t contain any moving parts or fans at all.
