Railway applications - Axlebox condition monitoring - Interface and design requirements - Part 2: Performance and design requirements of on-board systems for temperature monitoring
This European Standard defines the minimum performance requirements of on-board monitoring systems for axlebox condition monitoring by means of temperature measurements. This European Standard refers to temperature monitoring of the axlebox. However, the design may be such that the rolling bearing itself is monitored directly. The requirements of this European Standard are intended to apply equally to basic monitoring systems for monitoring the axlebox temperature through to more technically complex systems that may employ a combination of mechatronics. To ensure the compatibility of monitoring systems and the effective monitoring functions, this European Standard defines the requirements in the following areas: equipment and characteristics; monitoring performance; operation and interface. This part of EN 15437 does not include: systems that do not give an indication to the driver; how an on-board monitoring system is structured and how it measures the temperature and identifies axlebox position. This is considered part of equipment design and not part of the functional requirements set out in this standard; operational requirements for acting on the information reported by the on-board monitoring system; operational requirements for conflict of information between trackside monitoring systems and on-board monitoring systems; maintenance requirements for on-board temperature monitoring systems.
Bahnanwendungen - Zustandsüberwachung von Radsatzlagern - Leistungsanforderungen - Teil 2: Fahrzeugbasierte Systeme für Temperaturüberwachung
Diese Europäische Norm legt die Mindestanforderungen an fahrzeugbasierte Systeme zur Überwachung von Radsatzlagern durch Temperaturmessungen fest.
Diese Europäische Norm bezieht sich auf die Temperaturüberwachung der Radsatzlagerung. Jedoch kann die Konstruktion so erfolgen, dass das Wälzlager selbst direkt überwacht wird.
Die Anforderungen dieser Europäischen Norm sind sowohl zur Anwendung bei Basisüberwachungssystemen als auch zur Überwachung der Radsatzlagerungstemperatur durch technisch komplexere Systeme bestimmt, die Mechatronik einsetzen können.
Um die Kompatibilität von Überwachungssystemen und den effektiven Überwachungsfunktionen sicherstellen zu können, legt diese Europäische Norm die Anforderungen in den folgenden Bereichen fest:
Ausrüstungsteile und Eigenschaften;
Überwachungsfunktion;
Betrieb und Schnittstellen.
Dieser Teil der EN 15437 enthält nicht:
Systeme, die keine Anzeige für den Triebfahrzeugführer bereitstellen;
wie ein fahrzeugbasiertes Überwachungssystem strukturiert ist und wie es die Temperatur misst und die Position der Radsatzlagerung identifiziert. Dies wird als Teil der Konstruktion von Ausrüstungsteilen betrachtet und nicht als Teil der funktionellen Anforderungen, die in dieser Norm festgelegt werden;
betriebliche Anforderungen für das Reagieren auf die durch das fahrzeugbasierte Überwachungssystem übertragenen Informationen;
betriebliche Anforderungen für Konflikte von Informationen zwischen streckenseitigen Überwachungs-systemen und fahrzeugbasierten Überwachungssystemen;
Anforderungen an die Wartung von fahrzeugbasierten Temperaturüberwachungssystemen.

La présente norme européenne définit les exigences de performance minimales applicables aux systèmes embarqués pour la surveillance des boîtes d’essieux au moyen de mesures de température.
La présente norme européenne se réfère à la surveillance de la température des boîtes d’essieux. Cependant, la conception peut être telle que le roulement lui-même fasse directement l’objet de la surveillance.
Les exigences de la présente norme s’appliquent aussi bien aux systèmes basiques de surveillance de la température des boîtes d’essieux qu’aux systèmes techniquement plus complexes qui peuvent employer une combinaison de systèmes mécatroniques.
Pour assurer la compatibilité des systèmes et l’efficacité des fonctions de surveillance, la présente norme définit les exigences dans les secteurs suivants :
équipement et caractéristiques ;
performances de surveillance ;
fonctionnement et interface.
La présente partie de l’EN 15437 ne couvre pas :
les systèmes qui ne donnent pas d’indications au conducteur ;
la structure, la mesure de la température et l’identification de la position des boîtes d’essieux du système embarqué de surveillance de la température. Ceci est considéré comme faisant partie des caractéristiques de conception des équipements, et comme ne faisant pas partie des exigences fonctionnelles définis dans la présente norme ;
les exigences opérationnelles pour agir sur les informations transmises par le système embarqué de surveillance de la température ;
les exigences opérationnelles en cas de contradiction entre les informations transmises par le système de surveillance installé le long des voies et le système embarqué ;
les exigences relatives à la maintenance des systèmes embarqués de surveillance de la température.

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by March 2013, and conflicting national standards shall be withdrawn at the latest by March 2013. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. EN 15437 "Railway applications - Axlebox condition monitoring - Interface and design requirements” is comprised of the following parts: Part 1: Track side equipment and rolling stock axlebox; Part 2: Performance and design requirements of on-board systems for temperature monitoring (the present document). According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.
SIST EN 15437-2:2014
EN 15437-2:2012 (E) 4 Introduction Failed wheelset bearings on rolling stock create a hazard to the safe operation of the railway. If a bearing fails while rolling stock is in service there is the potential for a catastrophic event. A catastrophic event may result in fatalities, severe damage to rolling stock and/or the infrastructure and a risk that rolling stock may derail and/or a fire may develop. One indication that a bearing is about to fail is a rise in the heat generated by the bearing. Bearings that are about to fail may, therefore, be detected by monitoring their temperature to identify an unacceptable rise. This part of EN 15437 covers the monitoring of axlebox bearing temperature by on-board monitoring systems. According to the application, these may be considered to be basic systems or advanced systems. In most cases, rolling stock axleboxes continue to be monitored by trackside Hot AxleBox Detectors [HABD] which is the subject of Part 1 of EN 15437. The monitoring system is fitted on the rolling stock and is able to function autonomously from trackside monitoring systems which are ground-based. In contrast to trackside monitoring systems, the detection characteristic may be adapted to the particular vehicle design, such that the alarm levels employed are configured depending on the bearing properties, sensor arrangement, vehicle type, network characteristics, etc. The use of on-board monitoring may also provide a solution for overcoming constraints related to bogie design or other aspects of vehicle design or operation which may prevent effective monitoring by means of the track-side monitoring systems. Other devices which apply functionally equivalent alternatives (for example based on the principle of vibration monitoring) may be available and normalized elsewhere, such as in other parts of this series of European
Standards. SIST EN 15437-2:2014

Introduction
Failed wheelset bearings on rolling stock create a hazard to the safe operation of the railway. If a bearing fails
whilst rolling stock is in service there is the potential for a catastrophic event. A catastrophic event may result
in fatalities, severe damage to rolling stock and/or the infrastructure and a risk that rolling stock may derail
and/or a fire may develop.
One indication that a bearing is about to fail is a rise in the heat generated by the bearing. Bearings that are
about to fail may therefore be detected by monitoring their temperature to identify an unacceptable rise.
This part of EN 15437 covers the monitoring of axle box bearing temperature by onboard systems.
It was developed by Working Group 35 Hot Box Detection of CEN Technical Committee 256 Railway
Applications. It defines the minimum requirements for the equipment, monitoring performance, operation and
interface in order to provide temperature-based diagnostic information to the onboard diagnosis system.
In most cases, axle boxes continue to be monitored by trackside Hot Axle Bearing Detectors which is the
subject of Part 1 of EN15437.For onboard systems, the notable features are that the supervision is performed
in a continuous way, based on inputs from temperature sensors. Further, that the system is fitted onboard the
train and is able to function autonomously from trackside systems which by nature are ground-based.
In contrast to trackside monitoring systems, the detection characteristic may be adapted to the particular
vehicle design, such that the alarm levels employed are configured depending on the bearing properties,
sensor arrangement, vehicle type, network characteristics, etc…
The use of onboard monitoring may also provide a solution for overcoming constraints related to bogie design
or other aspects of vehicle design or operation which may prevent effective monitoring by means of the track-
side systems.
Other devices which apply functionally equivalent alternatives (for example based on the principle of vibration
monitoring) may be available and normalized elsewhere, such as in other parts of this series of EN standards.

1 Scope
This part of EN 15437 defines the minimum performance requirements of onboard systems for axle box
condition monitoring by means of temperature measurements. Such systems are required in order to satisfy
the applicable essential requirements of the European Directives for Interoperability.
NOTE this does not exclude use of this standard (or selected parts) in other cases, for example applications involving
speeds or vehicle design where the TSI requirements are not applicable.
To ensure the compatibility of systems and the effective monitoring functions, this standard defines the
requirements in the following areas:
Equipment and characteristics
Monitoring performance
Operation & Interface
The outcome (interface) of the onboard detection is the provision of diagnostic information to the appropriate
interface and the scope is entirely onboard, as illustrated in Figure 1.
Key
1 sensors (part of the onboard monitoring system)
2 monitoring unit (part of the onboard monitoring system)
3 interface to train diagnostic system (part of the onboard monitoring system)
4 interface to JRU (part of the onboard monitoring system)

The scope of this part (part 2) of the standard does not include:
how a onboard temperature monitoring system measures the temperature and identifies axle box
position. This is part of an individual equipment design and not part of the functional requirements of this
standard;
operational requirements for acting on the information reported by the onboard temperature monitoring
system;
operational requirements for conflict of information between trackside HABD and onboard systems, this is
a matter that has to be discussed and procedure agreed with Infrastructure Manager and Railway
Undertaking;
maintenance requirements for onboard temperature monitoring system.
