REMOTE CONTROL OF TRAM RAIL-SWITCHES HEATING

There has been resolved tram crossings supervision. Among others topics the tram rail-switches heating control was also covered. It is standing alone system, no external control is required. On the other hand the supervisor can take control over. All needed operational data are transmitted back to the supervisor station.  The supervising staff is informed about heating progress, about problems with rail-switch direction changing and about trolley wire electricity drop-out. History list of all occured events is also there. The above described system is based upon GPRS network and FARCOM 8DI/8DO modules.

TRAM CROSSINGS SUPERVISION

The MPC module drives and checks tram rail-switches. The tram rail-switches are controlled by RS485 interface and binary inputs. They connect inductive loops a give information about passing trams.

ACOUSTIC MESSAGES SYSTEM

The public traffic tools are widely extended by MPC-A module. It helps with traffic coordination by sending remote acoustic messages. The module is equipped by 4 independent audio outputs. All messages are stored on SD card. The driving commands can be routed via GPRS network.
