Attention is drawn to the possibility that

This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association,

EN 15437 “Railway applications - Axlebox condition monitoring - Interface and design requirements” is comprised of the following parts

20、: 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

21、 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, Ro

DIN EN 15437-2:2012-12 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 i

23、s 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

24、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 b

25、e 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

26、 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 characteristic

27、s, 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 equivalen

28、t 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. DIN EN 15437-2:2012-12 EN 15437-2:2012 (E) 5 1 Scope This European Standard defines the minimum performance requirements

29、 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 Stan

30、dard 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 Sta

31、ndard 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

32、 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

33、information between trackside monitoring systems and on-board monitoring systems; maintenance requirements for on-board temperature monitoring systems. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its appli

39、rail vehicle directly to the wheel set 3.3 rolling bearing bearing operating with rolling motion between the parts, supporting load and moving in relation to each other 3.4 on-board monitoring system system that is capable of detecting a temperature of an axlebox that is indicative of the health of

40、that axlebox and indicates when acceptable temperature conditions have been exceeded 3.5 Safety Integrity Level (SIL) one of a number of defined discrete levels to specify the safety integrity requirements of the safety functions to be allocated to the safety related systems Note 1 to entry: The Saf

41、ety Integrity Level with the highest figure has the highest level of safety integrity. 4 Equipment and characteristics 4.1 Design requirements The equipment shall respect the applicable requirements regarding the environmental conditions for equipment on-board rolling stock as set out in EN 50125-1.

42、 In particular, vibration design of electrical and electronic equipment, as well as their fixing, associated with the measurements on the bearing unit or on the axle box shall respect the requirements set out in EN 61373. The equipment shall respect the applicable requirements regarding electronic e

43、quipment as set out in EN 50155. On-board monitoring systems shall not interfere or influence the behaviour of trackside equipment or other train-borne equipment. NOTE This document does not set out the architecture of the environment in which an on-board temperature monitoring system may be install

44、ed. The range of architectures may differ significantly (from a freight wagon to a high DIN EN 15437-2:2012-12 EN 15437-2:2012 (E) 7 speed EMU) and therefore the level of protection required for each installation may be quite different. It is the responsibility of the system installer to establish i

45、f the specification of an on-board temperature monitoring system (including any protection for interference from external sources such as electricity or heat) is suitable for the architecture in which it is to be installed and to perform. 4.2 Reliability The reliability of the on-board monitoring sy

46、stem shall be expressed according to the methods set out in EN 50129. This is to enable the Railway Undertaking (or other responsible entity) to satisfy their requirements when making a risk analysis (concerning rolling stock running with an undetected hot axlebox), for example as described in EN 50

47、126-1. 4.3 Description of alarm levels Temperature limits shall be determined for alarm levels depending on the bearing properties, sensor arrangement, vehicle type, network characteristics, etc. as follows: Alarm level 1 (“hot” alarm): The temperature limit, indicative of the condition of a bearing

48、, above which damage will occur to the bearing and/or its functionality, with the potential to lead to a hazardous event. Alarm level 2 (“warm” alarm): The temperature limit, indicative of the condition of a bearing, above which accelerated deterioration of its serviceability is anticipated to occur. The axle box tests undertaken as part of the requirements set out in EN 12082 can provide an indication of the values to whic
