  • To introduce and expand the automation on the control and

supervision activities on lines and hubs of the railway network

  • To upgrade the infrastructure maintenance procedures in an

innovative way, by using computer based systems and modern diagnostic systems

  • To realize a new operational and prescriptive model of the
  • rganization and of the work procedures based on the model

agreed with the Customer

  • To increase the quality of services offered to users according

to concepts of uniformity, efficiency and safety

Why the Customer needs SCC ?

  • The SCC-TMS is fully integrated with all the other SCC

sub-systems (PIS, D&M, CCTV)

  • At Control Center level the same Hardware architecture is

applied for all the SCC sub-systems

  • The Control Center LAN is unique and connects all the

various equipment

  • Different Dispatchers, depending upon Customer

Organization, are present to govern Traffic, Diagnostics and Infrastructures

SCC - The Traffic Management System (TMS)

12

TMS Introduces and expands the automation on the control and supervision activities

Automation & control

  • CTC (management of indications and controls);
  • Train Stepping (or Tracking) and Train Management;
  • Event Logging, Recording and Playback

Supervision activities

  • Traffic Regulation and Planning (forecasting)
  • Conflict display and Resolution
  • Train Movement under Abnormal Conditions
  • Traffic Optimization
  • Real time platform assignment in large stations
  • Information Management

SCC – Diagnostic & Maintenance

The SCC D&M System is based on three hierarchical level: OCC, PMan and PP. The main functions of the D&M System are:

  • Diagnostic and Maintenance of the peripheral equipment (IXL, TLC and

AUX eqp.);

  • Alarm management
  • Diagnostic of the SCC components (HW, SW, LAN);
  • Management of spares (location, inventory, replacement);
  • Management of system documentation (displaying of all the project

documentation via a standard browser)

17

D&M upgrades the infrastructure maintenance procedures in an innovative way, using computer based systems and modern diagnostic systems

slide-18
SLIDE 18

Ansaldo Segnalamento Ferroviario

Alarms are managed according to the following classification:

SCC - Alarms Management

18

Supervision alarms: Command and Control system and communication networks. System ALARMS Circulation data management and train alarms: automatic control and train tracking anomalies. Circulation ALARMS Indication/control and signalling equipment alarms: they are generated on the basis of IXL checks, and indicate the anomalous field unit status. Auxiliary equipment alarms (acquired by the CTC as checks): fire, intrusion and power supply alarms. Signalling ALARMS Alarms signalled by the button and presented in the specific page Type of alarm

slide-19
SLIDE 19

Ansaldo Segnalamento Ferroviario

For each alarm the following data are reported:

  • type (serious or medium);
  • nature (persistent or impulsive);
  • request (if any) for recognition;
  • acknowledge / not acknowledge status (if relevant);
  • date / time of occurrence;
  • place of occurrence (if relevant);
  • concerned field unit (if relevant);
  • text description.

SCC – Tele-Surveillance and Security

The TSS main functions are:

  • CCTV System in each controlled Station
  • Connection to the Control Centre via high-speed TLC channels
  • Local recording (for control or alarm event)
  • Anti-intrusion and fire alarm management
  • Interface to the Control Centre Building Automation and to the D&M

System

  • Emergency management (Crisis room)

22

Increase the quality of services The TSS system is independent from the Traffic Management but it provides operators workplaces in the OCC with functionalities to govern critical situations.

Since 2002, ASF Service supplies technical assistance and maintenance on SCC products. According with SCC contracts, purchasers were expected to be supplied with 2 years warranty, both on HW and SW products, so ASF Service started collecting and managing customers’ requests. Collaboration with Research&Development, project management and commissioning was fundamental.
