EN 61375-1:2012

Electronic railway equipment - Train communication network (TCN) - Part 1: General architecture

IEC 61375-1:2012 applies to the architecture of data communication systems in open trains, i.e. it covers the architecture of a communication system for the data communication between vehicles of the said open trains, the data communication within the vehicles and the data communication from train to the ground. The applicability of this part of IEC 61375 to the train network technologies allows for interoperability of individual vehicles within open trains in international traffic. The main technical change of this new edition with regard to the previous edition consists of a new structure of the complete IEC 61375 series.

Elektronische Betriebsmittel für Bahnen – Zug-Kommunikations-Netzwerk (TCN) – Teil 1: Allgemeiner Aufbau

Matériel électronique ferroviaire - Réseau embarqué de train (TCN) - Partie 1: Architecture générale

La CEI 61375-1:2012 s'applique à l'architecture des systèmes de communication de données dans les trains à composition variable, c'est-à-dire qu'elle couvre l'architecture d'un système de communication de données entre les véhicules des trains considérés, les communications de données dans les véhicules et les communications de données train-sol. L'application de la présente partie de la CEI 61375 aux technologies de réseau de train permet l'interopérabilité de véhicules individuels dans des trains à composition variable en trafic international. La principale modification technique de cette nouvelle édition par rapport à l'édition précédente consiste en une nouvelle structuration de la série CEI 61375.

Železniške elektronske naprave - Komunikacijsko omrežje vlaka - 1. del: TCN - Splošna arhitektura komunikacijskega omrežja (IEC 61375-1:2012)

Ta del standarda IEC 61375 se uporablja za arhitekturo podatkovnih komunikacijskih sistemov na odprtih vlakih, in sicer zajema arhitekturo komunikacijskega sistema za podatkovno komunikacijo med vozili navedenih odprtih vlakov, podatkovno komunikacijo v vozilih in podatkovno komunikacijo med vlakom in tiri. Uporaba tega dela standarda IEC 61375 za tehnologije omrežja vlaka omogoča interoperabilnost posameznih vozil odprtih vlakov v mednarodnem prometu. Podatkovni komunikacijski sistemi v vozilih so navedeni kot priporočljive rešitve za uporabo navedenega komunikacijskega omrežja vlaka (TCN). V vsakem primeru mora združljivost predlagane hrbtenice vlaka s predlaganim omrežjem kompozicije dokazati dobavitelj. Ta del standarda IEC 61375 se lahko uporablja tudi za zaprte vlake in vlake z večdelnimi enotami, če se o tem dogovorita kupec in dobavitelj.
