Definitions
- the invention relates to a method and an arrangement for monitoring track sections by means of wheel sensors, in particular by means of double sensors each consisting of two sensor elements arranged spatially offset in the direction of the track.
- wheel sensors typically in the form of so-called double sensors, which consist of two sensor elements arranged spatially offset in the direction of the track, are arranged in opposite end regions of the track section to be monitored, and counting pulses are generated when they are passed. By comparing the counting pulses at both ends of the monitored track section, it can then be determined whether the track section is free or occupied.
- Inductive proximity switches are typically used as sensors, as are known, for example, from DE 2326 089 A1, DE 32 34651 A1 and DE 33 13 805 A1. They comprise at least one sensor element, typically in the form of an AC-powered oscillating circuit coil, which responds to a relative movement between the sensor element and a metal object, e.g. a railway wheel rolling past the sensor element, and triggers a pulse which can be used, for example, to count or trigger certain control signals . If the sensor element is an AC-fed resonant circuit coil, also known as a response coil, this is typically connected to a capacitor to form an LC resonant circuit and is located in a quiescent current monitoring circuit.
- AC-fed resonant circuit coil also known as a response coil
- a proposal from the first category can be found in DE 199 15 597 A1, which proposes a wheel sensor with two oscillating circuit coils fed with alternating current in order to make it possible to detect induced interference voltages to suppress and to achieve a particularly high level of immunity to interference from electromagnetic interaction with the eddy current brakes used in many rail vehicles when the same work in the detection range of the coils.
- Proposals of the second category can be found, for example, in DE 196 06 320 A1, which proposes a method for handling hardware failures in track vacancy detection using axle counting, and EP 0662 898 B1, which proposes a device for automatic correction axle counting errors, and EP 1 498 338 B1, which proposes a method for determining the occupancy status of a track section, in particular after a restart of an axle counting system.
- the two wheel sensors in one end area were and are (to make the evaluation easy to handle) linked to only one wheel sensor in the opposite end area, ie the axle counting circuits AC and BD are formed, for example. If a sensor fails, another axle counting circuit is still available. If a sensor in the second axle counting circuit fails, there is no longer any axle counting circuit available, regardless of the end area in which the sensor is located. According to the teaching DE 102005 048 852 A1, on the other hand, would still have a functioning axle counting circuit even if a wheel sensor failed in each end area.
- the invention is based on the object of specifying a method and an arrangement for monitoring track sections using wheel sensors, in which the evaluation can be carried out in a particularly simple and fail-safe manner such that the method and the arrangement can be scaled as desired, i.e. even with complex arrangements of Track sections with several switches, such as are often found in shunting areas, can be implemented with high availability, with the method and arrangement being particularly flexible in configuring, so that a combination of redundantly designed and non-redundantly designed axle counting points is also possible.
- the invention is based on the new approach of not designing the axle counting circuits redundantly, ie forming as many axle counting circuits as possible from the existing wheel sensors, but rather in those end areas in which this is required to form redundantly designed axle counting points and only to connect these axle counting points with one another, so that only a single axle counting circuit is formed for each track section.
- any redundant wheel sensors that may be present are not first linked in a higher-level axle counting unit, but rather in the opposite end areas.
- axle counting unit when wheel sensors are retrofitted to form redundant axle counting points, the new wheel sensors do not have to be wired to an existing axle counting unit, with a particular advantage of the invention being that despite conversion to redundantly designed axle counting points, existing axle counting units can continue to be used because, from the point of view of The respective axle counting unit does not change anything: it continues to receive only one signal from each axle counting station, regardless of whether the axle counting station only has one wheel sensor or several wheel sensors. This also eliminates the time-consuming re-approval of the axle counting unit.
- axle counting station is understood here to mean an axle counting station in which one of the two wheel sensors or, if the wheel sensors consist of several sensor elements, several sensor elements can fail without this leading to the failure of the axle counting station.
- wheel sensors are linked to one another "in the redundantly designed axle counting points"
- the voters are usually arranged in a junction box to which the respective wheel sensors are connected. The junction box is then connected to an axle counting unit.
- opposite end areas is understood to mean end areas of a track section to be monitored, which must be monitored in order to determine whether the track section is free.
- a simple switch comprises three opposite end regions, namely one at the tip and two at the root.
- the two axle counting stations are linked together in a 1oo2 architecture to form the axle counting circuit.
- XooY architecture (pronounced “X out of Y architecture”) refers to a logical evaluation, where Y indicates the number of elements linked together and X indicates the number of elements that must fail in order to To cause total failure of the evaluation.
- the evaluation can be implemented as a hardware circuit or by software.
- a 1oo2 architecture two elements are linked together, with catastrophic failure occurring if one of the elements fails.
- the elements linked together in such an architecture can be individual sensor elements of a double sensor, but also complete double sensors or wheel sensors, axle counting points or axle counting circuits.
- evaluation failed refers here to the case in which it is no longer possible to evaluate the information supplied by the individual elements.
- the larger X is in relation to Y, whereby X can of course at most be equal to Y, because at most as many elements can fail as there are elements, the greater the availability of the evaluation.
- the two wheel sensors of a redundantly designed axle counting station are linked to form the respective axle counting station in a 2oo2 architecture.
- two double sensors are used as wheel sensors to form a redundantly designed axle counting point, with each double sensor consisting of two sensor elements arranged spatially offset in the direction of the track and the two sensor elements of each double sensor being linked to one another in a 1 oo2 architecture. If one sensor element fails, the corresponding double sensor fails, but there is still a functioning double sensor in the respective axle counting station.
- the four sensor elements of the two double sensors of a redundantly designed axle counting point can be used to form the respective axle counting point in a 3oo4 architecture be linked together.
- the four sensor elements are preferably arranged spatially offset from one another in each end region in the direction of the track.
- a great advantage of the invention is its easy scalability. If the monitored track section has more than two end areas, as is the case with a switch, only one axle counting point is added per end area, while the solution from the prior art described above, in which each of two is provided in one end area Wheel sensors is linked to each wheel sensor provided in the opposite end area, the number of axle counting circuits increases exponentially. If the monitored section of track includes a switch with one end area at the tip and two end areas at the root, it is sufficient to simply form one axle counting circle from the axle counting point at the tip and the two axle counting points at the root.
- axle counting point can be integrated into the axle counting circuit according to the invention.
- axle counting points are formed from the wheel sensors in the opposite end areas, with at least one of the axle counting points being designed redundantly and comprising two wheel sensors linked to one another, each redundantly designed axle counting station includes a voter for linking the two respective wheel sensors and a single axle counting circuit is formed from the axle counting stations.
- the voters can be implemented as a hardware circuit or by software.
- the two axle counting stations are linked together in a 1oo2 architecture to form the axle counting circuit.
- the voters of a redundantly designed axle counting station are designed to link the respective wheel sensors to one another in a 2oo2 architecture.
- the wheel sensors of a redundantly designed axle counting station are preferably double sensors, with each double sensor consisting of two sensor elements arranged spatially offset in the direction of the track and the two sensor elements of each double sensor being linked to one another in a 1oo2 architecture.
- the wheels of a redundantly designed axle counting station are double sensors, with each double sensor consisting of two sensor elements that are spatially offset in the direction of the track, the voters of a redundantly designed axle counting station can be designed to combine the four sensor elements of the two double sensors to form the respective axle counting station in one to link the 3oo4 architecture together.
- the four sensor elements provided to form a redundantly designed axle counting station can then be arranged spatially offset from one another in the direction of the track.
- each redundantly designed axle counting point can be designed to generate counting pulses by means of the two double sensors when at least two spatially offset sensor elements of the four sensor elements respond at different times.
- Evaluation electronics can be provided for this purpose.
- the track section to be monitored is a branched track section with more than two end areas, e.g. a switch, and an axle counting point is provided in each end area, the axle counting points can be linked to form a single axle counting circuit.
- a simple turnout with one track section at the tip and two track sections at the root, it is sufficient to form only one axle counting circuit using one axle counting point at the tip and two axle counting points on the two track strands at the root.
- the voters of redundantly designed axle counting stations are each connected to an axle counting unit via an interface to form the axle counting circuit
- the wheel sensors of each redundantly designed axle counting station are connected to the respective voter via an interface and all interfaces are defined the same.
- the interfaces can, for example, be power interfaces, i.e. cables, via which the axle counting unit supplies power to the axle counting stations and monitors its course. However, it can also be almost any other interface such as a CAN bus.

- FIG. 8 shows an evaluation scheme of the second exemplary embodiment of the invention.
- FIG. 9 shows, in a highly schematized form, a simple switch with six wheel sensors arranged to monitor the individual tracks of the switch.
- Fig. 1 shows a schematic plan view of a track section to be monitored, designated in its entirety by 10, of a track consisting of two rails 14 and 16 laid on a number of sleepers 12, only a few of which have been provided with reference symbols for reasons of clarity, wherein in Two wheel sensors A and B or C and D are arranged in two opposite end regions 18 and 20 of the track section 10 to be monitored.
- each wheel sensor A, B, C, D is in the form of a double sensor consisting of two sensor elements A1, A2, B1, B2, C1, C2, D1, D2, with each double sensor of the "inductive proximity switch" type being individual sensor elements A1, A2, B1, B2, C1, C2, D1, D2 are AC-fed oscillating circuit coils.
- the invention is not limited to the use of double sensors and in particular inductive proximity switches - in principle, any type of sensor that makes it possible to detect the passing of a wheel or an axle is suitable for realizing the idea of the invention.
- double sensors have the great advantage of being able to detect the actual passing and not just a so-called swinging motion, in that it is checked whether the sensor elements of the respective double sensor, which are spatially offset one behind the other along the track, are triggered.
- the arrangement is such that a train traveling from left to right in the drawing first enters the detection areas of sensor elements A1 and B1, then enters the detection areas of sensor elements A2 and B2.
- a train traveling from right to left would first enter the detection range of sensor elements C1 and D1 and then the detection range of sensor elements C2 and D2, this arrangement being made purely by way of example.
- FIG. 2 shows in a highly schematic manner the time profiles 22 and 24 of signals from the two sensor elements A1 and A2 of the double switch A, i.e. it forms a diagram of the response of the two sensor elements from FIG. 1 when a metal train wheel drives past .
- "Signal progression" here means the change in a specific measured variable over time, and accordingly the time is plotted in any desired unit on the abscissa.
- the signal curves 22 and 24 are shown without dimensions and offset one above the other for the purpose of easier understanding.
- the measured variable can be, for example, a current through the respective coil, which then does not rise and fall in a strictly rectangular manner, as shown in FIG. 2, but rather sinusoidally. If this were plotted on the ordinate and if the coils had the same quiescent current, the curves 22 and 24 would be superimposed and would only be offset in time. However, the steepness of the fall or rise is not relevant for understanding the figure.
- the object then moves further, it enters the detection range of the second sensor element A2 at time T2, as a result of which the signal curve 24 also changes.
- the detection ranges of the sensor elements are arranged in such a way that they spatially overlap and consequently there are also temporal overlapping ranges for objects moving in one direction, in particular an overlapping range 26 in which the object is detected by both sensor elements simultaneously while it is in the Time range 28 is detected only by the first, in the time range 30 only by the second sensor elements.
- the signal curves can be evaluated to generate counting pulses, but also to measure the speed. To count axles, ie to monitor a section of track, the procedure shown in FIG. 3 has been used up to now.
- Fig. 3 shows a highly schematized circuit diagram of a first arrangement according to the prior art for monitoring a track section, in whose opposite end areas (which are not provided with their own reference numbers) as shown in Fig. 1, two wheel sensors A and B or C and D are arranged, wherein the wheel sensors A and B are arranged in one end area, the wheel sensors C and D in the other end area.
- the wheel sensors A, B, C and D are each configured here as double sensors consisting of two sensor elements A1, A2, B1, B2, C1, O2, D1, D2.
- the two sensor elements of each double sensor are shown one above the other in the figure, but they are actually arranged next to one another in the direction of the track, as in FIG. This also applies to Figures 4, 5 and 7.
- the sensor elements A and B or C and D arranged in the two opposite end regions of the track section to be monitored are indicated by the dashed lines to form two Axle counting circuits 40 and 42 linked together in a 1oo2 architecture, i.e. the dual sensors A and C form a first axle counting circuit 40, and the dual sensors B and D form a second axle counting circuit 42.
- the two axle counting circuits 40 and 42 are linked to one another in a 2oo2 architecture, i.e. the monitoring formed in this way works as long as at least one of the two axle counting circuits 40 and 42 is working.
- a redundant design of the monitoring system is required, the type of formation of axle counting circuits shown is usually used because the corresponding evaluation of the sensor signals is easy to handle. However, it has a relatively low so-called availability, since no more axle counting circuits are available as soon as a single sensor element fails in each of the two axle counting circuits, regardless of where this sensor element is located. For example, if sensor elements A1 and D2 fail, no axle counting circuit is operational in the architecture shown. In order to remedy this problem, a redundant design of the axle counting circuits as shown in FIG. 4 was proposed in DE 10 2005 048 852 A1 mentioned at the outset.
- the wheel sensors A, B, C and D provided for monitoring the track section shown in Fig. 1, designed as double sensors each with two sensor elements, are linked to one another in such a way that each wheel sensor of each end area communicates with each wheel sensor of the opposite Sensor area is linked to form one axle counting circuit.
- a first axle counting circuit 40 from the wheel sensors A and C and a second axle counting circuit 42 from the wheel sensors B and D but also a third axle counting circuit 44 from the wheel sensors A and D and from the Wheel sensors B and C form a fourth axle counting circuit 46, with the wheel sensors being linked to one another in a 1oo2 architecture in each axle counting circuit.
- This link advantageously increases the availability of the arrangement, since wheel sensors provided in opposite end areas in the axle counting circuits 40 and 42 or, if the wheel sensors are designed as double sensors as here, the sensor elements forming the double sensors can fail without this happening as in Fig. 3 leads to a failure of the monitoring - if, for example, sensor elements A1 and D2 fail, the axle counting circuit 46 formed from the wheel sensors B and C is still available.
- this type of monitoring is extremely complex in terms of signal evaluation, since four axle counting circuits have to be evaluated even when monitoring a simple track section as in the track section with two end areas shown in FIG. If the monitored track section is a branched track section with three end areas, as is the case with a simple switch (see Fig.
- axle counting circuits namely the axle counting circuits, the axle counting circuits ACE, ACF, ADE, ADF, BCE, BCF, BDE and BDF, must already be evaluated.
- Such a type of monitoring is impractical for complex track areas such as shunting areas.
- the wheel sensors A, B, C and D again in the form of double sensors, are arranged in opposite end regions 18, 20 of the track section to be monitored, as in the previous figures linked to one another, that the sensors A and B or C and D lying in one and the same end region 18 or 20 each form an axle counting point 50 or 52 in a 2oo2 architecture. Only these two axle counting points 50 and 52 are then connected to one another in a 1oo2 architecture to form a single axle counting circuit 40 .
- the wheel sensors A and B or the wheel sensors C and D in the respective axle counting points 50 or 52 are linked by means of a voter 54 or 56, so that each axle counting point 50, 52 cannot be identified in terms of signals for the "outside world". is whether it is designed redundantly, i.e. includes two or more wheel sensors, or whether it is not designed redundantly, i.e. includes only one wheel sensor has axle counting points.
- the voters 54 and one 56 can each be connected via an interface 58 to a possibly already existing axle counting unit 60 by linking the two axle counting stations 50, 52 in a 1oo2 manner.
- the voters 54 and 56 can be implemented in a manner known per se using hardware or software.
- the wheel sensors A, B, C, D of the axle counting points 50, 52 which are designed redundantly here, are connected to the respective voter 54, 56 an interface 58 are connected in each case, with all interfaces being defined in the same way.
- interfaces can be as simple as cables.
- a particular advantage of the invention also results directly from Fig. 5 for the person skilled in the art: through the use of identically defined interfaces 58, existing axle counting systems in which a wheel sensor is currently connected directly to an axle counting unit 60 can be retrofitted, since from the point of view of the Axle counting unit 60 does not matter whether it communicates via the interfaces 58 with an axle counting point consisting of a wheel sensor or a number of wheel sensors.
- the arrangement shown in FIG. 5 has the same availability as that shown in FIG. 4, but has the great advantage that only one axle counting circuit 40 does not have to be evaluated, rather than four axle counting circuits. If the track section is a branched track section with more than two end areas, only one axle counting point is added for each end area. In the case of a simple switch, it is not necessary to evaluate eight axle counting circuits, as is the case with an arrangement according to FIG.
- FIG. 6 shows an evaluation scheme of the arrangement according to FIG. 5. If one imagines the individual sensor elements A1, A2, . . is only handled uniformly, an evaluation scheme results in which the sensor elements of each individual double sensor are connected in series, but the two wheel sensors in each end area are connected in parallel. As can be seen directly from the diagram in Fig. 6, a wheel sensor or, since the wheel sensors are designed here as double sensors, one or both of the sensor elements of the respective double sensor can fail in both end areas of the monitored track section, without the availability of the evaluation being impaired as a result would.
- FIG. 7 shows a circuit diagram according to a second exemplary embodiment of the invention.
- two axle counting points 50 and 52 are formed, with the sensor elements in each axle counting point being linked to one another here by means of a voter 62 or 64 in a 3oo4 architecture, which means the availability of the one shown in Fig. 5 Arrangement increased even further, because now sensor elements in different double sensors of the same end area can also fail without this leading to a failure of the evaluation.
- sensor elements A1 and B2 can fail, as can sensor elements C2 and D1, for example.
- the voters 62 and 64 can be implemented in a manner known per se using hardware or software.
- the sensor elements A1, A2, B1 and B2 can be linked to the voter 62 via interfaces not shown here, and the sensor elements C1, C2, D1 and D2 can be linked to the voter 64 via interfaces not shown here.
- the axle counting points 50 and 52 formed in this way are linked in a 1oo2 architecture to form the axle counting circuit 40, with the current wiring typically being such that the voters 62 and 64 are each connected to the axle counting unit 60 via an interface. Again, all interfaces can be defined identically.
- FIG. 9 is a highly schematic representation of a simple switch, denoted in its entirety by 66, with six wheel sensors A, B, C, D, E and F, which, like the wheel sensors shown above, can each be designed as double wheel sensors with two individual sensor elements. shown.
- the tracks, each of which naturally consists of two rails, are represented in the greatly simplified diagram of FIG. 9 by only a single common line.
- the two wheel sensors A and B are arranged along the track in the end region 18, the so-called pointed end of the points 66.
- a first axle counting point 50 is formed from the two double sensors A and B
- a second axle counting point 52 is formed from the wheel sensors C and D
- a third axle counting point 70 is formed from the wheel sensors E and F.
- axle counting circuit is then formed from the axle counting points 50, 52 and 70. If further tracks are added, the number of axle counting points integrated into the axle counting circuit increases by the number of track tracks to be added.
- the wheel sensors or, if the wheel sensors are designed as double sensors, the individual sensor elements can be linked, as shown in FIG. 5 or FIG. 7 .
- axle counting points are designed redundantly in the exemplary embodiments shown, the invention advantageously also allows combinations of redundant and non-redundant axle counting points and thus enables, among other things, a needs-based retrofitting of existing axle counting systems, in which it may be desirable to design only certain axle counting points redundantly, without doing so an elaborate one Having to rewire, and also an existing one
- Axle counting unit can continue to be used.
