(Main)Railway Applications - Technical parameters of train detection systems for the interoperability of the trans-European railway system - Part 2: Axle counters
Railway Applications - Technical parameters of train detection systems for the interoperability of the trans-European railway system - Part 2: Axle counters
This European Standard specifies parameters for the design and usage of Axle counter systems. For this, the standard specifies the technical parameters of Axle Counter systems associated with the magnetic field limits for RST in the context of interoperability. In addition test methods are defined for establishing the conformity and the performance of axle counter products. The specified parameters are structured and allocated according to their basic references as follows: - Axle counter system parameters - Train based parameters - Track based parameters - Environmental and other parameters Each parameter is defined by a short general description, the definition of the requirement, the relation to other standards and a procedure to show the fulfilment of the requirement as far as necessary. An overview on the safety relevance of each parameter is given in the context of this European Standard in a separate table. This European Standard is intended to be used to assess compliance of axle counter systems and other forms of Wheel Sensors used for train detection, in the context of the Interoperability Directive and the associated technical specification for interoperability relating to the control-command and signalling track-side subsystems. The bands and rolling stock emission limits are currently defined in the Axle Counter FRM as specified in the CCS TSI Index 77.

Železniške naprave - Osnovni parametri sistemov za detekcijo vlakov - 2. del: Števci osi
Ta evropski standard določa parametre za zasnovo in uporabo sistemov števcev osi. V ta namen standard določa tehnične parametre sistemov števcev osi, povezanih z omejitvami magnetnih polj za RST v okviru interoperabilnosti. Poleg tega so določene preskusne metode za ugotavljanje skladnosti in delovanja proizvodov, povezanih s števci osi.
Opredeljeni parametri so strukturirani in dodeljeni v skladu z njihovimi osnovnimi sklicevanji, kot sledi:
– parametri sistemov števcev osi;
– parametri na podlagi vlaka;
– parametri na podlagi tirov;
– okoljski in drugi parametri.
Vsak parameter je opredeljen s kratkim splošnim opisom, definicijo zahteve, povezavo z drugimi standardi in postopkom za prikaz izpolnitve zahteve, kolikor je potrebno. Pregled varnostnega pomena vsakega parametra je v okviru tega evropskega standarda podan v ločeni tabeli.
Ta evropski standard je namenjen uporabi za oceno skladnosti sistemov števcev osi in drugih oblik senzorjev na kolesih, ki se uporabljajo za detekcijo vlakov, v okviru evropske direktive o interoperabilnosti vseevropskega železniškega sistema in povezane tehnične specifikacije za interoperabilnost, ki se nanaša na podsistema za upravljanje-vodenje in signaliziranje ob progi.
Frekvenčni pasovi in omejitve emisij železniških vozil so trenutno opredeljeni v okviru upravljanja s frekvencami, kot je določeno v indeksu 77 CCS TSI.
