Transcript

  • 1. 1 Telecommunications & Train Control Conference 12/08/2014 Optimising the potential benefits of CBTC through system integration Aaron Fraser Senior Systems Engineer GE Transportation
  • 2. 2 Telecommunications & Train Control Conference 12/08/2014 Urban transportation systems Multiple levels of possible integration ANCILLARY SYSTEMS Fire detection CCTV Ventilation Passenger Information INTELLIGENT TRANSPORTATION SYSTEMS Passenger info Intermodal Vehicle to vehicle Traffic systems CBTC SUBSYSTEMS
  • 3. 3 CBTC WC 2013 11/08/2014 1. Optimise CBTC benefits via CBTC sub-system integration
  • 4. 4 Telecommunications & Train Control Conference 12/08/2014 Integration of (vital) CBTC subsystems Vision on the use of a unique Vital Platform  Robust architecture  Better design and installation  Lower Life Cycle Cost  Improved management of spares  Enhanced scaleability Benefits Flexible and easy to sustain A Unique platform means: 1. Same hardware (and low level S/W) for each subsystem 2. Standardised building blocks 3. No need to use gateways Unique Vital Platform
  • 5. 5 CBTC WC 2013 11/08/2014 2. Optimise CBTC benefits via integration with other Mass Transit Systems
  • 6. 6 Telecommunications & Train Control Conference 12/08/2014  In modern systems, radio and data communications assured by two independent networks: a signalling network and a non-signalling network New wireless broadband technologies enable unified communication networks with data flow segregation and prioritisation Integrate other systems through CBTC Communication networks
  • 7. 7 Telecommunications & Train Control Conference 12/08/2014 allows prioritisation and segregation of the data flow. It allocates resources defining:  Guaranteed Bit Rate  Prioritisation level  Profile (class) of Quality of Service  Fire Alarms  Rolling Stock system alarms (brakes, power system, air conditioning)  End-customers experience: − Additional broadband for Mobile communication (re-selling) − Entertainment (internet, TV) Integrate other systems through CBTC Unified signalling communication networks: converging vital & non vital data More QoS level than other wireless technology to meet the urban multi service requirements Other possible applications: On Board data
  • 8. 8 Telecommunications & Train Control Conference 12/08/2014 Case Study
  • 9. 9 Telecommunications & Train Control Conference 12/08/2014 Daegu Metro – South Korea Tuesday morning, February 18th, 2003 9:48 am:  Kim Dae-Hwan, 56, an unemployed taxi driver with serious mental disorders, boards train 1079.  He brings a milk carton, filled with a flammable liquid and a lighter. 9:52 am:  Train 1079 stops at Joongang station.  During the stop, Kim ignites and throws the milk carton This incident caused 130 injuries and 134 casualties of which only 12 were onboard the train. Why?
  • 10. 10 Telecommunications & Train Control Conference 12/08/2014 The operator in the Emergency Control Room (equipped with CCTV): 9:54 am: 1. decides to cut the traction power at platform area 2. turns off the lighting of the station (passengers found the platform full of smoke and dark). 9:55 am: 3. activates the ventilation system (not enough to disperse the smoke) 4. reports the fire to authorities, but 5. does not report the fire to the Operational Control Centre of the subway nor to other trains. Daegu Metro – South Korea In the Emergency Control Room
  • 11. 11 Telecommunications & Train Control Conference 12/08/2014 09:56 am:  With its route correctly set by the ATS and validated by the Interlocking, another train, number 1080, departs from the previous station towards Joongang station  Without knowledge of the fire, the driver of train 1080 arrives at the station, sees the fire and informs the passengers to remain calm. Train 1080 catches fire immediately At this point the driver of train 1080: 1. tries to restart the train again, but the traction power has been cut. 2. panics and escapes from the train, taking the train key with him. 3. the key withdrawal causes the train doors to close, leaving passengers trapped inside ...

  • 12. 12 Telecommunications & Train Control Conference 12/08/2014 Rescuers found four of the six cars of train 1080 with the doors closed. 90% of the casualties were found in these cars. Sources: Korea Times and BBC. Daegu Metro – South Korea On the tracks
  • 13. 13 Telecommunications & Train Control Conference 12/08/2014 What if systems had been integrated through the CBTC DCS?
  • 14. 14 Telecommunications & Train Control Conference 12/08/2014 Fire detection alarm activated No route set for any train to the station on fire What if the Fire Detection system was integrated with the Interlocking? DCS
  • 15. 15 Telecommunications & Train Control Conference 12/08/2014 Evacuate area ! PIS – Passenger Info System What if the Fire Detection system was integrated with PIS? Passengers could be aware of the situation sooner. Emergency Exits could be displayed helping passengers to find a way out. Fire detection alarm activated DCS
  • 16. 16 Telecommunications & Train Control Conference 12/08/2014 Tunnel ventilation system disperses smoke What if the Fire Detection system was integrated with the Ventilation System? Fire detection alarm activated DCS
  • 17. 17 Telecommunications & Train Control Conference 12/08/2014 Data messages (SMS) warning about the fire could be quickly sent to the station staff mobile phones. What if the Fire Detection system was integrated with staff mobile phones Fire detection alarm activated DCS
  • 18. 18 CBTC WC 2013 11/08/2014 3. Optimise CBTC benefits via integration with Intelligent Transportation Systems
  • 19. 19 Telecommunications & Train Control Conference 12/08/2014 19 CBTC WC 2013 11/08/2014 Industrial Internet … opening new possibilities
