19、chnical Committee CEN/TC 278, “Road Transport and Traffic Telematics“, the secretariat of which is held by NEN.

EN 13149-2:2004 (E) 4 1 Scope This document defines the cab
22、ling specifications for an onboard data transmission bus between the different parts of equipment for service operations and monitoring of the fleet. This document is applicable to equipment installed onboard buses, trolley buses and tramways only as part of a bus fleet operation. This equipment inc
23、lude operations aid systems, automatic passenger information systems, fare collection systems, etc. Equipment directly related to the functioning of the vehicle (e.g. driver dashboard, engine management, brake systems, door opening systems) are excluded from the scope of this document and are dealt
24、with in other standardisation bodies. This document is not applicable to tramways operated as part of a train, subway or metro operation. Two alternative transmission buses will be accepted. This document refers to one of them (known as WORLFIP and specified in EN 50170). A second set of standards w
25、ill be published for the other solution (so called CAN). The selected bus system, between the two standardised alternatives, shall be subject to an agreement between each transport operating organisation and its equipment providers. This document covers the link between equipment inside a single veh
26、icle. Although it could be applied to multiple vehicles, this application is not explicitly covered by this document. This document is the second part of a set of standards related to the onboard transmission bus, which will define the following aspects for each allowed transmission bus: choice of t

29、cation and service definition (IEC 61158-2:1993) 3 Cabling specifications 3.1 General remarks The principles for the coupling of devices to the data transmission bus focus upon the longer term objectives which are to achieve the least necessary number of variants, rather than to allow for the profus
30、ion of interim and migratory solutions which may occur initially. This is especially important for public transport road vehicles, which are generally equipped in different non-correlated stages (for example, first the fare collection system, then the radio and automatic location system some months
31、or years later, etc.) EN 13149-2:2004 (E) 5 It is important to understand that electrical connections onto the bus have some impact upon the network performance, and that the practice is dependant upon the principles relevant to transmission lines rather than simple electrical power circuits. Since
32、one of the main objectives is to provide the minimum amount of cabling on vehicles the basic power concepts are also covered with flexibility to suit different circumstances. 3.2 Characteristic impedance The main trunk circuit shall be a single pair twisted and shielded cable of nominal characterist
33、ic impedance of 150 Ohms at 1Mhz with overall braided shield. This shall not be connected in the form of a ring. 3.3 Polarity The polarity of the signal conductors shall be maintained throughout the trunk: Pair 1 Wire 1 (White) - Data + Wire 2 (Black) - Data - 3.4 Signal conductors The signal conduc
34、tors shall not be used for powering any devices. 3.5 Connections between devices The one pair cable can be run between devices in a daisy chain fashion but shall be terminated with a 150 resistor at each end.

35、een devices 3.6 Connection/disconnection of a device To avoid the disruption to the trunk continuity when a device is removed, the cable shall be joined on the trunk side of the device connector. This will allow removal of a device without causing a failure to the remaining network. EN 13149-2:2004
36、(E) 6 Key A device 1 D data Figure 2 Connection/disconnection of a device 3.7 Spur length To minimise the mismatch caused by a spur, the cable connection at the device shall be within 2,5 cm of the coupling transformer.

38、-When a connection that breaks into the trunk circuit is required a tap connection can be provided. This could be provided using a two pair branch cable. 3.9 Branch cable polarity: The polarity of the signal conductors shall be maintained.

The screen continuity shall be maintained by the drain wire. The cable sheath shall be clamped to provide strain relief. See Figu

EXAMPLE To comply with the above branch cables of 0,7 m could be applied where devices are clustered onto the trunk. This would provide six lengths o
43、f 0,7 m = 4,2 m which exceeds the 4 m minimum.

44、in Figure 8. Figure 8 Multiple clusters Where there is a requirement to cluster devices, for example within an equipment rack, and connections to the trunk are made via a wired backplane, then active multi-port couplers (see Figure 9) or matching devices such as passive attenuators (see Figure 10) s
45、hould be applied either side of the cluster. See EN 61158-2:1994, section 12.2.2, Network Configuration rule No. 8.

46、hield ground connection The trunk cable shield shall be connected directly to the vehicle ground at one point only. It is recommended that this shall be close to the vehicle power supply. The tail connection shall not be common to other power return circuits and the resistances shall be as shown in
47、Figure 11: Key A vehicle battery B power feeds C trunk shield D tail E vehicle chassis F other power returns Figure 11 Shield ground connection The tail connection shall be installed in a manner that minimises inductive or electrostatic coupling from other circuits or equipment on the vehicle. The t
48、ail connection shall be crimped onto a ring terminal, which shall be connected onto the ground terminal of one of the tap boxes. 3.14 Shield connections at a device The cable shield connections at devices shall remain insulated from the vehicle chassis except as above and devices should be connected
