SANS 53149-1:2009This standard may only be used and printed by approved subscription and freemailing clients of the SABS.EN 13149-1 :2004 (E) 4 Introduction The present situation is the following: A large

    20、number of Vehicle Scheduling and Control Systems (VSCS) do not use a data bus, resulting in point to point data links with expensive cabling which cannot be preinstalled during the manufacturing of the vehicle, increasing the cost of the system different proprietary transmission protocols which have

    21、 to be implemented as and when required difficulty in changing the provider of a given type of equipment as no compatibility exists between different providers of the same type of equipment Some systems implement the VDV IBIS bus specification, but: IBIS bus is very slow and no longer covers the nee

    22、d for high speed data transmission between equipment IBIS bus is not an open system and does not cover some of the necessary messages practically every VSCS manufacturer has been obliged to implement a second high speed data bus which is proprietary, resulting in no possibility of interchanging equi

    23、pment with other manufacturers The buses, which are proposed by CEN/TC278, aim at avoiding the preceding difficulties with the following characteristics: high capacity and high speed data bus consistent workplan ensuring interoperability down to the message level low cost solution already standardis

    24、ed data bus large number of already existing and future applications outside the VSCS area, ensuring the existence of equipment on the market, the progressive decrease of the cost of the necessary chips and the timelessness of the solution existing chips and basic software up to and including the la

    25、yer 7 of the ISO 7 layer communication model and existing developments tools, minimising the development costs The buses proposed by CEN/TC 278 have been chosen among others through a progressive selection process. This work took into account a flexible approach to the range of applications, the pot

    26、ential traffic loading under different operating circumstances and the definition of objective criteria for a transmission bus. The candidate buses were evaluated against the criteria in terms of performance, cost, industrial support and the existence of maintained documents. SANS 53149-1:2009This s

    28、 monitoring of the fleet. This applies to equipment installed onboard buses, trolleybuses and tramways only as part of a bus fleet operation. It excludes tramways when they are operated as part of a train, subway or metro operation. The equipment includes operations aid systems, automatic passenger

    29、information systems, fare collection systems, etc The equipment directly related to the functioning of the vehicle (driver dashboard, engine management, brake systems, door opening systems, etc.) are excluded from the scope of the present document and are dealt with in other standardisation bodies.

    30、Two alternative transmission buses will be accepted. This document refers to the so called WORLDFIP bus. A second set of documents will be published for the second solution (so called CAN). There is no ranking between the two solutions and the selected bus system, between the two standardised altern

The present document refers to the so-called OSI transmission model and covers OSI layers 1,2,7, the other layers are not used in our applications. The present document covers the link

    32、 between equipment inside a single vehicle. Although it could be applied to multiple vehicles, this application is not explicitly covered by this document. The present document is the first part of a set of standards, related to the onboard transmission bus, which will comprise, for each allowed tra

    33、nsmission bus, the following set of documents: a) choice of the bus and general applications rules (EN 13149-1) b) cabling specifications (EN 13149-2) c) messages content specifications (prCEN TS 13149-3) 2 Normative references The following referenced documents are indispensable for the application

    34、 of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

The following are particularly relevant and shall apply. 5.2.2 Network medium This consists of shielded twisted pair wires mainly used in a linear topology 5.2.3 Transmission speed The devices connected to the bus shall operate at the nominal rate of 1Mbit/second. 5.2.4 Coupling mode The coupling

    44、 of a device to the medium shall be by the voltage mode (parallel coupling) using transformers. 5.2.5 Redundant media Four wire configurations providing a medium redundancy network are permitted but not mandatory 5.2.6 Network configuration rules The network configuration rules of EN 61158-2:1994, s

    45、ection 12 shall apply with the exception that the limit to 32 devices on a bus applies only to a bus segment. The bus can consist of more than one segment resulting in more than 32 devices attached to the same bus. SANS 53149-1:2009This standard may only be used and printed by approved subscription
