The Cactus traffic management system

Centralized Traffic Control (CTC)

All the basic features for centralised control and supervision are included in the system, and the latest network technology means that the Operations Control Centre can be placed and managed from a single location of your choice. Extensive integration means that graphical interfaces can include information from parallel or sub-systems and other technical systems. This minimizes the number of screens on your desk.

Display management

Customers can customise symbols and icons. The overviews are generally based on a “macro object”, commonly an entire station. These objects are then modified to create the various overviews required: detailed view, general view, panoramas or panel view.

This provides operators with the opportunity to choose the overviews required for the particular operation. A tool is included that makes it possible to create new objects or modify existing ones.

Interlocking systems

The system employs various types of PLC systems for use in communications with older relay interlocking systems. Modern electronic interlocking systems are connected via the supplier’s protocol. Complete protocols are available for use with BTRCS’s Ebilock family and Union Switch’s
ML II.

Cactus UniView develops the protocols you need. The protocol is always provided with detailed logs that give us total control of the interfaces. If new projects require new protocols, this is an integral part of the project.

Automatic route setting

The manual management of routing can be performed in a number of different ways, giving dispatchers a variety of options. The most common method for input is the mouse, but keyboard command options are also available for the operators who prefer to go on working in the way they are accustomed to.

The system can be used for predictive routing according to schedule. But if dispatcher authorises it, optimised routing can be used according to specific situations. In the event of routing conflicts, evaluated alternatives will support the dispatcher’s decision. Operators also have access to a number of tuning parameters. Automatic route setting provides dispatchers with more time to do their other tasks or concentrate on dealing with problem situations.

Timetables & Train number

The technology to import timetables is customised to suit your specific operations. You can use excel files or allocate an SQL database for network imports. The standard procedure is to assign each train a unique identity derived from the service timetable. Trains are tracked by way of log at each arrival and departure, and these times are compared to the timetable. Colour-coded images instantly convey information about delays, making it possible to take action fast.

By touching a train number on the screen, the operator gains direct access to the detailed timetable for that particular train. At the same time they can see a progress report for the train’s arrivals and departures en route.
