The present document specifies the choice and the general application¿s rules of an onboard data
transmission bus between the different equipment for service operations and 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 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.
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 alternatives, shall be subject to an agreement between each transport operating
organisation and its equipment providers.
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 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 transmission bus, the following set of documents:
a) choice of the bus and general application¿s rules (EN 13149-1)
b) cabling specifications (EN 13149-2)
c) message¿s content specifications (prCEN TS 13149-3)
Die Möglichkeiten und die allgemeinen Anwendungsrichtlinien für die bordeigene Datenübertragung der verschiedenen Geräte für die Bedienung und Flottenüberwachung sind festgelegt. Diese Festlegungen sind nur anzuwenden für Installationen in Bussen, Oberleitungsbussen und Straßenbahnen, die im Rahmen einer Flotte betrieben werden, und beziehen sich auf Betriebsunterstützungssysteme, automatische Informationssysteme für Fahrgäste, Systeme zur Fahrpreissammlung, ua. Systeme, die direkt die Bedienung des Fahrzeuges betreffen, wie Türöffnungssysteme oder Bremssysteme, sind nicht von dieser Norm betroffen. Die vorliegende Norm behandelt die Verbindung zwischen den Geräten eines Einzelfahrzeuges und bezieht sich auf die sogenannten WORLFIP-Übertragungsleitungen.
