EN 50155:2017

Railway applications - Rolling stock - Electronic equipment

This European Standard applies to all electronic equipment for control, regulation, protection, diagnostic, energy supply, etc. installed on rail vehicles. For the purpose of this European Standard, electronic equipment is defined as equipment mainly composed of semiconductor devices and recognized associated components. These components will mainly be mounted on printed boards. Sensors (current, voltage, speed, etc.) and Semiconductor drive unit (SDU) for power electronic devices are covered by this standard. Complete Semiconductor drive unit (SDU) and power converters are covered by EN 61287 1. This European Standard covers the conditions of operation, design requirements, documentation, and testing of electronic equipment, as well as basic hardware and software requirements considered necessary for compliant and reliable equipment. Specific requirements related to practices necessary to ensure defined levels of functional safety will be determined in accordance with relevant railway safety standards. The software requirements for on board railway equipment are specified by EN 50657.

Bahnanwendungen - Elektronische Einrichtungen auf Schienenfahrzeugen

Applications ferroviaires - Équipements électroniques utilisés sur le matériel roulant

Le présent projet de Norme européenne s'applique à tous les équipements électroniques de commande, de régulation, de protection, de diagnostic, d'alimentation, etc. montés sur des véhicules ferroviaires. Pour les besoins du présent projet de Norme européenne, un équipement électronique est défini comme étant un équipement composé principalement de dispositifs à semiconducteurs et des composants qui y sont associés. Ces composants sont généralement montés sur des circuits imprimés. Les capteurs (de courant, tension, vitesse, etc.) et les circuits imprimés d'allumage des équipements électroniques de puissance sont couverts par la présente Norme. Les allumeurs et circuits de puissance électroniques complets sont couverts par l'EN 61287-1. Le présent projet de Norme européenne couvre les conditions de fonctionnement, les exigences de conception, la documentation et les essais des équipements électroniques, ainsi que les exigences matérielles et logicielles de base considérées comme nécessaires pour assurer la conformité et la fiabilité des équipements. Les exigences spécifiques relatives aux pratiques nécessaires pour assurer des niveaux définis de sécurité de fonctionnement sont déterminées conformément aux normes de sécurité ferroviaire correspondantes. Sous réserve des spécifications de l'alinéa ci-dessus, le logiciel relève du domaine d'application de la présente Norme tant qu'une norme pertinente relative aux logiciels embarqués sur les matériels roulants n'est pas disponible. NOTE Une norme relative aux logiciels embarqués sur les matériels roulants (à l'exception des logiciels de commande et de protection des trains) est en cours d’élaboration.

Železniške naprave - Vozna sredstva - Elektronska oprema

Ta osnutek evropskega standarda se uporablja za vso elektronsko opremo za nadzor, regulacijo, zaščito, diagnosticiranje napajanje itd., ki je nameščena na železniška vozila.
Za namene tega osnutka evropskega standarda je elektronska oprema definirana kot oprema, sestavljena predvsem iz polprevodniških naprav in priznanih pripadajočih sestavnih delov. Ti sestavni deli se bodo namestili predvsem na tiskana vezja.
Ta standard zajema tipala (za tok, napetost, hitrost itd.) in sestave plošč tiskanih vezij sprožilnih enot za močnostne naprave. Celoten seznam sprožilnih enot in močnostnih elektronskih tokokrogov je podan v standardu EN 61287-1.
Ta osnutek evropskega standarda zajema pogoje za obratovanje, zahteve za načrtovanje, dokumentacijo in preskušanje elektronske opreme ter osnovne zahteve glede strojne in programske opreme, ki se obravnavajo kot nujne za skladno in zanesljivo opremo.
Posebne zahteve v zvezi s praksami, ki so potrebne za zagotovitev določenih ravni funkcionalne varnosti, bodo določene v skladu z ustreznimi železniškimi varnostnimi standardi.
Ob upoštevanju zgornjega odstavka programska oprema spada na področje uporabe tega standarda, dokler ni na voljo ustreznega standarda za programsko opremo na voznih sredstvih.
OPOMBA: Standard za programsko opremo na voznih sredstvih (razen programske opreme za nadzor in zaščito vlakov) je v pripravi.
