International Electrotechnical Commission IEC (International Electrotechnical Commission) TC9 (Electrical Traction Equipment) in a joint effort with UIC (Union Internationale des Chemins de Fer) set up WG22 (Working Group 22), to characterize a Train Communication Network railroads administrators: makers: Chinese Railways Adtranz (CH, DE, SE) DB (Germany) ANSALDO (IT) FS (Italy) CAF (E) JRRI (Japan) Ercole Marelli Trazione/Firema NS (Netherlands) GEC-Alsthom (F, GB, B) RATP (France) Mitsubishi (JP) SNCF (France) Siemens (GB, DE) PKN (Poland) Toshiba (JP) Westinghouse Signals (GB) assembled in the UIC (Union Internationale des Chemins de Fer)

Slide 3

Working Group 22 undertaking TC9 made WG22 in 1988 to characterize interfaces between programmable types of gear, with the point of accomplishing attachment similarity: 1) between vehicles 2) between hardware on board a vehicle:

Slide 4

Working Group 22 Method of Work Establish the client\'s necessities (particularly UIC) Study existing arrangements (Profibus, LON, FIP, MIL 1553, CAN, ...) Build on rail lines demonstrated arrangements upheld by railroads makers Implement before institutionalize Solve protected innovation issues Ensure reasonable access to the innovation Test on full scale Define a Conformance test

Slide 5

Two-level Architecture vehicle transport gadgets The Train Communication Network comprises of: • a Train Bus which associates the vehicles (Interface 1) and of • a Vehicle Bus which associates the supplies inside a vehicle (Interface 2). Vehicle and prepare transport are interconnected by a hub going about as entryway

Slide 6

Type of Trains WG22 recognizes two primary sorts of trains: Open Trains Example: universal traveler trains. made out of vehicles regularly coupled and uncoupled in operation prepare transport is naturally reconfigured amid income benefit FS DB SNCF Example: TGV, ICE, Metro, Suburban trains. Shut Train Sets made out of vehicles not detachable in operation. prepare transport is arranged disconnected by driver or in progress

Slide 7

Technical Requirements ( Topology Two-level chain of command: Train transport associating Vehicle Busses. Traverse • Train transport: 850 m (1000m) , 32 hubs. • Vehicle transport: 200 m, 32 stations, 256 basic gadgets. Medium Twisted wire match or optical fiber (no cajole). A form of the prepare transport might utilize the current UIC or EP lines. Operation Train transport: programmed setup of the prepare transport in under 1 second, with left-right distinguishing proof. Movement • time-basic, short process information (footing control, prepare control,...) transmited occasionally with a deterministic deferral of <100 ms from end to end of the prepare transport, resp. <50 ms on the vehicle transport. • less time-basic messages (analytic, traveler information,...) transmitted on request with dependable stream control and mistake recuperation from end to end. Agree to railroads environment, particularly IEC 571. Unwavering quality Redundant setup conceivable to expand accessibility.

Slide 8

TCN Bus Candidates for Train and Vehicle Bus Positive Negative IEC/ISA SP50 developing universal field transport not economically accessible - still in hot standard open deliberation, complex higher layers. FIP field transport, deterministic, whole number, national standard, unverifiable future, few upheld by EdF, ENEL usage, expensive chips. Profibus handle transport, shabby coupling, whole number, national standard, dubious future. Moderate, huge support in Germany few stations, complex higher layers. MIL 1553 railroads and aviation encounter expensive (transformers, chips, devices). Deficient respectability (equality). ARINC 625 aviation encounter expensive (transformers, chips, devices). Bitbus basic, across the board moderate, reliance on Intel. Producer not willing to open the product. BRELNET, ITDC, railroads encounter producer does not longing to open it. EKENET (deterministic Ethernet) Factor chips stopped, not open. railroads encounter Tornad* depends on benchmarks expensive stations, maker not willing to open the physical level, no support CAN, A-BUS straightforward, shabby, vehicle encounter moderate, feeble, non-deterministic. great idea of higher layers, instruments, LON moderate, non-deterministic, risky. various leveled design.

Slide 9

Use of Commercial Networks Theory: Use of industrially broadly accessible parts and programming diminish improvement expenses and assurance long haul accessibility Reality: There are very few railroads reviewed arrange segments available. Business parts must be altered to the application. Substantial volume venders have little sympathy toward the little railroads showcase Companies in the PC business are less steady than rail routes firms. Life-time is 5 years for business segments, 15 years for mechanical items, however 30 years for railroads - shouldn\'t something be said about the most recent 15 years ? In this manner: WG22 chose to choose just transports which have been railroads demonstrated and which are upheld by in-house producing capacity.

Slide 10

Evaluation Results • Evaluated transports: BRELNET, CD450, DIN 43322, Profibus, Modiac, IEC Field transport, Tornad, Tornad*, FIP, Factor, Arlic, Ekenet, Bitbus, CAN, ARINC 1553, MICAS, ITDC, ISA SP50. • Only FIP, ARINC 1553, MIL 1553 and MICAS have quick, deterministic reaction (1 ms) • Most transports fizzled due to inadequate trustworthiness or absence of repetition. • Only LON bolstered a two-level pecking order (organize layer), yet needed constant reaction. • Only MICAS met the specialized necessities and was at that point being used in railroads. Its adjusted form was renamed MVB. • The WTB is a change of DIN 43322, assuming control over the CD450 encounter. • The correspondence programming was planned particularly for the TCN, to bolster countless and straightforward stations.

Slide 12

Wire Train Bus (WTB) standard correspondence interface between vehicles hub fundamental application open trains with variable structure, for example, UIC trains secured separate 860 m number of hubs 32 information rate 1\'000\'000 piece/second over protected, bent wires reaction time 25 ms initiation allocates to every hub its consecutive address and introduction encounter in view of DB-transport, FS-ETR450 and SBB Huckepack status completely tried on ERRI prepare, vehicles in operation

Slide 13

WTB Wiring Uses jumper links or programmed couplers between vehicles. Fritting (voltage heartbeats) is utilized to conquer oxydation of contacts Since there are typically two jumpers, the wiring is essentially excess: The UIC determined another link ( 18 post) good with the 13-shaft UIC connector

Slide 14

WTB - New UIC Cable The UIC disposed of the past thought of decommissioning existing UIC lines and consented to present an extra protected wire combine for the Train Bus: 9 5 11 12 7 8 10 6 15 1 20 16 3 4 14 2 X Train Bus wire match Y as per UIC 558 handout However, SNCF and DB couldn\'t concur whether to bring an extra wire match into the UIC-link or into the EP-brake link. The EP link prepares SNCF mentors, yet couple of worldwide mentors have it. In any case, all late cargo vehicles have it. ERRI tried both media for transmitting information, with no reasonable prevalence.

Slide 15

WTB Nodes Setup and Inauguration Autonumbering of hubs and decision of the ace inside 1,0 s. All hubs know their position in the transport and recognize ideal from left. All hubs are educated of the qualities of every other hub before general operation. If there should arise an occurrence of ace disappointment, whatever other hub assumes control.

Slide 16

WTB: The Vehicle Interface WG22 indicated the Wire Train Bus as the standard interface for attachment similarity between hardware situated on various vehicles. WTB is proposed principally for open (trains with variable structure, for example, UIC global trains. WTB considers the prerequisites of administrators, of makers and of the UIC 5R Pilot Group, communicated in handout UIC556. Handle Data traded over WTB are indicated in UIC handout 556, to allow vehicles of various starting point to convey without equivocalness. Diagnostics messages traded over WTB are characterized in UIC handout 557.
