Microprocessor centralized traffic control system MDC-U

Microprocessor centralized traffic control system MDC-U

MDC-U – is a complex of technical and software tools intended for creation of dispatch centralization systems (DC) providing control and management of train traffic.

Implementation of DC on the basis of MDC-U will allow to

Control from a single location -

the Transportation Control Center (TCC) - train traffic at stations, open tracks and long-distance sections

Automate

the traffic schedule maintenance and management process based on the predictive traffic schedule

Provide the TCC personnel with information

on the situation in the dispatching section and on the status of Signalling, Centralization, Blocking (SCB) and DC devices

Store archived information

for a long period of time with the option to view it in animation mode with adjustable playback speed

Key features

High system reliability and availability:

MDC-U equipment (servers, dispatchers' workstations, communication channels) is redundant, data processing in linear points is implemented according to the 2oo3d scheme

All interfaces are provided for connection

with any relay and microprocessor electrical interlocking, automatic and semi-automatic blocking systems, which allows the transmission of complete information on train position to the higher-level systems

Modularity and flexibility.

DC is easily configured for any arrangement of tracks

Integrated functions

for generating responsible control commands (SIL4)

Cyber security.

System protection against cyberattacks from external networks is guaranteed

Efficiency in maintenance.

Exclusion of routine maintenance operations due to diagnostics of railway automatics devices, monitoring of analogue and discrete signals and automated generation of reporting forms with subsequent analysis and identification of pre-failure states and failures of SCB devices

Main functions

Monitoring and control of the train traffic process

at the dispatching section by commands of the train dispatcher

Display of information on the train situation

at the dispatcher's section, status of SCB and DC devices on the operating personnel's workstation

Maintaining a schedule of completed train traffic

Automation of the control process

based on the predicted train schedule (“auto dispatcher” function)

Dispatching or station (local) control of linear points

Control of power supply systems

Recording actions of operating and maintenance personnel,

archiving all received information and generation of necessary protocols and reports

The MDC-U integrates the functions of SCB diagnostics systems, which excludes the requirement for additional equipment at separate points when creating regional rolling stock monitoring centres – all information from the archives will be transmitted via existing digital interfaces.

Integration of AKRO-C functions (centralization system of remote-control equipment for rolling stock) into MDC-U will allow remote monitoring of the rolling stock running parts condition.

For spans with coded automatic block signalling, it is available to interconnect the interlocking networks of signal installations and level crossings by means of a specialized controller.
