Definitions
- the invention relates to a device for measuring axle or bearing temperatures for locating hot runners or overheated brakes in rolling rail traffic, in which the infrared rays of the measuring points are directed to an infrared receiver via an oscillating oscillating mirror, with infrared rays being emitted transversely to the longitudinal direction of the rail in the defined by the oscillation of the oscillating mirror scanning plane.
- Devices of the type mentioned are described for example in AT 395 571 B or AT 398 413 B.
- Devices of this type are also referred to as hot runner location systems (HOA), and depending on the measuring range detected, analogous devices can also be used to detect blocking brakes or other impermissibly heated parts of rail vehicles.
- thermal detectors such as, for example, bolometers or rapidly responding heat radiation sensors, such as, for example, HgCd, HgTe, InSb, PbSe or combinations of such semiconductors are used as detectors.
- Such semiconductor detectors respond to changes by thermal excitation of free charge carriers and are able to resolve radiation of a high pulse train, but are not suitable for the continuous detection of a certain temperature level without additional devices, such as modulators or deflection devices, which interrupt the incident beam cyclically or direct it to other temperature levels suitable.
- Devices of this type are usually arranged in the track area and the measuring beam reaches the generally cooled detector through a window in the device and corresponding deflection devices.
- the arrangement is such that the active window, including a win- kels to the normal warehouse of a rolling rail vehicle can capture.
- a series of special evaluation methods were developed, with which the hottest point of an axis or a bearing can be detected across the longitudinal direction of the rail, using a special measuring and evaluation method, e.g. in AT 398 413 B is described.
- a common disadvantage of the previously known device is that greatly different wheel sizes, in particular different wheel sizes in passenger cars or heavy-duty cars, in particular so-called low-floor cars, significantly influence the possible scanning area, which is derived from the distance of the oscillating mirror from the scanning surface. Due to the geometry of different vehicles and in particular the geometry of different bearings, it is generally very difficult with a single device to detect several scanning surfaces simultaneously with different wagon groups.
- the invention now aims to provide a simple device of the type mentioned at the outset with an oscillating oscillating mirror which detects a scanning plane with which it is possible, regardless of the geometry of the respective rolling vehicles, to have defined positions in the region of the axis of a vehicle , especially bearing axles, brakes, such as disc brakes or other possibly inadmissibly heated parts, and to obtain complete information with just a single detector device.
- the device according to the invention essentially consists in that at least two deflecting mirrors are arranged within the scanning plane at a distance from one another transversely to the longitudinal direction of the rail, the deflected infrared rays of which are recorded in chronological order in accordance with the oscillation of the oscillating mirror.
- a plurality of measuring areas or measuring points can be deflected into a defined scanning plane corresponding to the oscillation of the oscillating mirror and fed to a common detector if the deflecting mirrors assigned to the individual measuring points are arranged at a lateral distance from one another. and in the course of the scanning the deflected infrared rays are directed onto the infrared detector in chronological order due to the oscillation of the oscillating mirror.
- the design according to the invention is such that the deflecting mirrors are designed as deflecting mirrors rotating about an axis normal to the mirror plane.
- Such rotating deflecting mirrors can in turn throw off dust particles impinging on the mirror surface by centrifugal force at a correspondingly high rotational speed, so that a self-cleaning effect of the deflecting mirrors is observed.
- the design can advantageously be such that the planes of the mirror surfaces of the deflecting mirrors are arranged essentially parallel to one another. If such mirror surfaces of the deflecting mirrors are arranged essentially parallel to one another, a plurality of positions located above them can each be assigned to such a deflecting mirror within the scanning plane defined by the oscillating mirror and can be successively detected, a particularly simple compensation of superposition signals when changing from a deflecting mirror to the next deflecting mirror within the oscillation range of the oscillating mirror is made possible.
- the design is such that the deflecting mirrors are arranged in a different height or different vertical distance from the driving plane or relative to the plane spanned by the rail sleepers are.
- an essentially parallel arrangement of the planes of the mirror surfaces of the deflecting mirrors such an offset transversely to the longitudinal direction of the rail or in the longitudinal direction of the threshold axis leads to the detection of exact positions of an axis or a bearing, without the optical axis of the detector having to be inclined in such a way that it could be affected by different geometrical designs of the chassis of vehicles.
- the design according to the invention is advantageously made such that the rotating deflecting mirrors are arranged within a hollow threshold and that the threshold has openings or windows for the passage of infrared rays in the vertical direction above the respective mirrors.
- the rotating deflecting mirror itself can be arranged in a protected manner and a plurality of measuring points or measuring ranges can be reliably detected with a narrowly defined scanning angle and not disturbed by external influences within the scanning plane defined by the oscillation of the mirror.
- the breakthroughs or windows of the threshold can be protected in a suitable manner by infrared-transparent glasses or by screens or sliders, so that the risk of soiling of the mirrors can be significantly reduced.
- the design is advantageously made such that the optical axis of the entrance lens of the detector containing the oscillating oscillating mirror and the infrared receiver runs essentially parallel to the driving plane.
- Such an orientation of the optical axis of the optics of the detector and in particular of the optical axis of the entrance lens of the detector allows the detector itself to be arranged in a protected manner, for example within a hollow threshold, so that it is impaired by mechanical influences or by contamination can be further reduced.
- this design makes it possible to ensure that the measuring beam cannot be interrupted in any way, even in the case of parts hanging down from low-floor wagons or wagons, and therefore the required measured values can be made available safely for all axes.
- the configuration is advantageously such that the planes of the deflecting mirrors are arranged inclined at approximately 45 ° to the driving plane, the optical axis of the entry lens of the detector preferably being arranged axially or axially parallel within the hollow threshold in the longitudinal direction of the threshold.
- An exact assignment to measuring ranges or measuring points, such as bearings or disc brakes, which are offset in the longitudinal direction of the axes, is advantageously achieved in that the deflecting mirrors are arranged below the measuring points to be recorded, a particularly high measuring accuracy being ensured if the rotating deflecting mirrors are arranged within the vertical projection of the respective measuring surface. In this way, the entire measuring surface is scanned in the oscillation region of the oscillating mirror, so that complete information about the axial width of the region to be measured can be obtained.
- the deflection mirrors are designed as convex or concave deflection mirrors.
- the scanning area can be enlarged and when using a concave mirror, the scanning area can be restricted.
- FIG. 1 shows a schematic arrangement of two rotating deflecting mirrors relative to a detector a vibrating mirror
- FIG. 2 shows a schematic arrangement of the device inside a hollow measuring threshold.
- two rotating deflecting mirrors 1 and 2 are arranged offset by a distance a in the axial direction of a threshold, the detector 3 being at an axial distance from the two rotating deflecting mirrors 1 and 2 with an essentially horizontal axis 4 of the input optics or input lens 5 is arranged.
- the axis 4 designates the central beam which, with the interposition of the focusing optical element, namely the input lens 5, reaches an image field lens 6. 7 with an autocollimation element is referred to, in which the temperature of the infrared detector 8 is a corresponding oscillating position of the oscillating mirror 9 is reflected on itself, so that a reference value can be obtained.
- the oscillating mirror 9 oscillates in the direction of the double arrow 10, thereby spanning a scanning plane running in the plane of the drawing and, in the course of the oscillating oscillation of the oscillating mirror 9, first a first partial scan over the region b with the intermediate switching of the deflecting mirror 2 and subsequently another partial scan via an axial one Length c takes place using the deflection mirror 1, the respective measuring beams lying in the plane being detected by the detector 8 in time sequence by the angular ranges ⁇ and ⁇ .
- a further rotating mirror not shown, enables the scanning of further measuring points, such as a disc brake.
- plane mirrors or, as indicated in FIG. 1 with dashed lines, convex or concave mirrors can be used.
- the detector 3 and the two rotating mirrors 1 and 2 are arranged inside a hollow measuring threshold 11, the optical axis 4 essentially coinciding with the longitudinal axis of the measuring threshold 11.
- the measuring threshold has windows 12 and 13 through which the partial area to be measured outgoing infrared rays can reach the deflecting mirrors 1 and 2, which windows 12 and 13 can be closed with sliders.
- the measuring beam entering through the window 13 is oriented in such a way that a partial area d of a bearing in the direction of the axis of the bearing can be detected and the corresponding temperature measurement values can be detected by the detector via this partial area d.
- the partial area lying above the measuring window 12 is a partial area of the axis 14 of a rail vehicle, the wheel of which is designated by 15.
- the rail itself is indicated schematically at 16 and is fixed transversely to the longitudinal axis of the sleeper on the sleeper.
- the windows 12 and 13 and optionally further windows can each be arranged vertically below the area to be measured, the axial central beam of the measuring device itself, i.e. the optical axis of the focussing optical element 5 can run protected horizontally inside the threshold, so that different designs of chassis and different dimensions of wheels and bearings can be interrupted just as little as by a hanging part of a vehicle.
