This European Standard shall be given the status of a national standard, either by publication of an identical text or by endo
19、rsement, at the latest by September 2009, and conflicting national standards shall be withdrawn at the latest by September 2009. 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

23、ntroduction Failed axle bearings on rolling stock create a hazard to the safe operation of the railway. If an axle 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 th
24、e 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 ri
25、se. World-wide experience shows that one way of managing the risk is by installing trackside Hot AxleBox Detectors (HABDs) to monitor the in-service temperature of rolling stock axleboxes. The sensors of a trackside HABD measure the thermal radiation emitted from the axleboxes of in-service rolling
26、stock. The level of thermal radiation is influenced by the emmissivity of the axlebox surface, which is influenced by the material, design, surface finish and operational conditions (dust, rain, etc). Even though operational conditions are continually changing the surface emmissivity of the axlebox,
27、 long term experience indicates that such changing conditions can be tolerated. This part of EN 15437 covers the monitoring of axlebox temperature by trackside HABD. It was developed by Working Group 35 “Hot Box Detection“ of CEN Technical Committee 256 Railway Applications. It defines the minimum r
28、equirements for the interface between a trackside HABD and rolling stock, to ensure that the system works. It is important to note that Clause 1, Scope, sets out the minimum requirements for the interface. The requirements set out in this document are based on long term existing rules, practices and
29、 procedures developed and currently in use by European member railway undertakings (RUs) and infrastructure managers (IMs). The following principles have been applied: a) The railway system requires technical rules in order to ensure an acceptable interface between rolling stock and trackside HABD.
30、b) In view of the increasing significance of international traffic, the standardisation of this interface is required. c) It is of particular importance that the existing level of safety and reliability is not compromised. d) The Cartesian co-ordinate system is used to define dimensions and position
31、s, that is X is longitudinal, Y is lateral and Z is vertical. Some rolling stock, according to their performance or design, is fitted with on-board equipment to monitor axle bearings for potential overheating. However, in most cases, axle bearings continue to be monitored by trackside Hot Axle Beari
32、ng Detectors which is the subject of this standard. Part 2 of EN 15437, which is currently being developed, covers on-board temperature monitoring of axle bearings. Alternative technology is available, or being developed, to monitor the condition of axle bearings, using vibration sensors, thermocoup
33、les, etc. and may in the future be addressed by additional parts to this standard. BS EN 15437-1:2009EN 15437-1:2009 (E) 5 1 Scope This part of EN15437 defines the minimum characteristics for the interface between a trackside Hot Axlebox Detector (HABD) and Rolling Stock (RST) that comply with the E
34、uropean Directives for Interoperability to ensure that the minimum functional requirement of the interface is achieved. The minimum requirements of the interface apply to: a) Rolling stock conforming to standard European railway gauge, that is 1435mm; b) Rolling stock axles fitted with outboard bear
35、ings; NOTE The design of rolling stock axles fitted with inboard bearings should respect the requirements set out in Note 2 of 5.2. c) Rolling stock with a maximum operational speed of up to and including 250 km/h; NOTE 1 That is conventional rail and class 2 high speed rail rolling stock as defined
36、 in the rolling stock TSIs. NOTE 2 Interoperable rolling stock designed for speeds above 250km/h (class 1 high speed rolling stock) are mandated to have on-board equipment for axlebox condition monitoring. The requirements for on-board equipment are described in part 2 of this standard which is curr
37、ently under development. NOTE 3 Interoperable rolling stock designed for speeds above 250km/h (class 1 high speed rolling stock) are outside the scope of this Part of the standard. However, if class 1 high speed trains are required to be monitored by HABDs their target area should comply with the re
38、quirements specified in this standard, except where stated otherwise. d) Trackside HABDs that are required to monitor conventional rail and class 2 high speed rail rolling stock. The rolling stock requirements of the interface are described in Clause 5 and for the HABD requirements of the interface
39、are described in Clause 6. The scope of this part (part 1) of the standard does not include: Hot Wheel (Hot Disc) Detectors (HWDs). However, HWD are often installed in combination with trackside HABD to provide a dual monitoring system. This standard does not prevent the use of such a combination; h
40、ow a HABD 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 HABD system; maintenance requirements for HABD syst
