MDC-U MICROPROCESSOR BASED CENTRALIZED TRAFFIC CONTROL SYSTEM

MDC-U – a hardware and software system designated to create systems of centralized traffic controls (DC) assuring monitoring and control of train movement at a specific railway section from a traffic management centre (CUP).

Main functions of MDC-U

• monitoring and controlling processes of train reception, dispatch, handling, overtaking at field stations of a subdivision by commands of a traffic controller;
• displaying reliable information on a train situation at a subdivision, state of the signalling and MDC-U devices at ARM of:

• train dispatchers (ARM DNC);
• signalling engineers (ARM ShD);

• keeping a traffic schedule (ARM GID);
• automating a control process in accordance with an expected train movement schedule (“automatic dispatcher” function);
• transferring field stations to a station (local) control;
• monitoring power supply systems;
• logging actions of operating and servicing personnel, archiving all information received, and generating required records and reports.

System advantages

• possibility of arrangement of additional remote ARMs for operating and maintenance personnel;
• remote monitoring of analog signals of different types and rates, allowing reducing time expenditures for servicing of the signalling devices;
• integration of field stations equipped with another type of DC;
• availability of a multiple-access indicator panel in CUP;
• long-term storage of archive information with the possibility of viewing in the “Movie” mode with the regulated speed of displaying.
