Many of the world’s railways have relay interlocking systems in operation and there is still much life left in this equipment. As new interlocking systems are computerised, the operator has a challenge to standardise the different Human-Machine Interfaces (HMI) of relay interlocking systems, normally controlled from a mosaic-type control desk, and electronic interlocking systems with inherent monitors and mouse control.
NetTrac 6653 Command 900 provides the capability to operate relay interlocking stations together with electronic interlocking systems on the same monitor and mouse of a centrally located workplace.
As is required by several operators, a vital display can be provided. This implies the possibility of picking up vital information from the screen at any time. A special “refresh” or “check” command is not needed. Generally two kinds of vital view are offered:
- Area overview
- Local focus view
Separate monitors for non-vital applications provide full MS Windows capabilities; for all vital and non-vital applications one common mouse is used.
- Minimised staff expenses by controlling several interlocking stations from a CTC centre
- Common HMI for different types of relay and electronic interlocking systems
- Permanent vital display
- Each vital application window can be displayed on each vital workstation monitor
- Non-vital applications provide full MS Windows capabilities
- Vital and non-vital TFT displays are controlled via one mouse
- No limitation regarding the number of operator workstations
- Crosswise access from different control centres to all sub-stations possible
- Fully redundant computer configuration in the control centre with automatic switch-over capability
