| Customer Requirements: |
| KAPP Engineering was approached by Maint-Elect
to design, supply and commission a PLC-based control system
to control the synchronised lifting of a 12-car train lifting
system for the new High-Speed Rail project in Taiwan. This system
allows the operators to lift a train in order to perform under-carriage
work or to repair/replace the bogies. |

| Solution: |
The control solution for this project comprises
of 13 x Koyo DL405 PLCs communicating over a high-speed Ethernet
network and interfacing to more than 2,000 I/O points. The system
is capable of performing 1, 3, 4, 8, and 12 car train lifting
operations, selectable via a UniOp touch screen installed at
the Main Control Centre. When lifting a multi-car train, the
control system synchronises the lifting process by ensuring
that all lifting platforms involved in the operation are raised
and lowered at the same rate. This requires high speed communications
between each of the lifting platforms, which the Ethernet communications
network is able to provide, updating all PLCs on the network
in less than 200 milliseconds. Graphical Operator Interface
Panels installed at the Main Control Centre and each Lifting
Station allow the operator to monitor and control the system
at any time. The operators can even select whether the information
is displayed in English or Chinese.
A graphical software package built around the KEPDirect I/O
Server has also been developed to allow the system designers
to dial into the control system from their office in Perth WA
to monitor and trouble-shoot the system. This value-adding feature
allows our client to offer continued support and maintenance
without the need to travel to Taiwan. |
