Description
Description
Sensor device for detecting a wheel moving along a rail
The invention relates to a sensor device for detecting a wheel moving along a rail, which sensor device has, on one side of the rail, two transmitting coils which are supplied with an alternating voltage and are arranged one behind the other with respect to a longitudinal direction of the rail and, on the other side of the rail, has two receiving devices with two receiving coils in each case which are connected to one another in series in opposite directions and are arranged one behind the other with respect to the longitudinal direction of the rail.
A sensor device of this kind is known in the form of a twochannel sensor head for detecting a rail vehicle wheel from the Polish patent specification PL 199810 Bl. In this context, the sensor head comprises a transmitting and a receiving head. The transmitting head has two transmitting coils, which are arranged one behind the other on one side of the rail in the longitudinal direction of the rail and are supplied with an alternating voltage. The receiving head arranged on the other side of the rail comprises two receiving devices with two receiving coils in each case which are connected to one another in series in opposite directions and likewise arranged one behind the other with respect to the longitudinal direction of the rail.
Embodiments of the present invention seek to provide a sensor device of the aforementioned type which is particularly advantageous with regard to its operational properties.
In accordance with an aspect of the present invention, there is provided a sensor device for detecting a wheel moving along a rail, which sensor device has, on one side of the rail, two transmitting coils which are supplied with an alternating voltage and are arranged one behind the other with respect to a longitudinal direction of the rail and, on the other side of the
2016287693 10 Jan 2019 rail, has two receiving devices with two receiving coils in each case which are connected to one another in series in opposite directions and likewise arranged one behind the other with respect to the longitudinal direction of the rail, wherein the sensor device has at least one further transmitting coil on the one side of the rail which is arranged between the transmitting coils with respect to the longitudinal direction of the rail, the transmitting coils and the at least one further transmitting coil are supplied with an alternating voltage of the same frequency and the magnetic flux generated by the at least one further transmitting coil is directed opposite to the magnetic fluxes generated by the transmitting coils.
In accordance with an aspect of the present invention, there is provided a wheel sensor having a sensor device according to the preceding aspect as well as an evaluation device linked to the receiving devices.
In accordance with an aspect of the present invention, there is provided a device for controlling and/or monitoring rail-bound traffic with at least one wheel sensor according to the preceding aspect.
Disclosed herein is a sensor device for detecting a wheel moving along a rail, which sensor device has, on one side of the rail, two transmitting coils which are supplied with an alternating voltage and are arranged one behind the other with respect to a longitudinal direction of the rail and, on the other side of the rail, has two receiving devices with two receiving coils in each case which are connected to one another in series in opposite directions and are arranged one behind the other with respect to the longitudinal direction of the rail, in that the sensor side of the rail which is arranged between the transmitting coils with respect to the longitudinal direction of the rail, that the transmitting coils and the at least one further device has at least one further transmitting coil on the one
2a
2016287693 10 Jan 2019 transmitting coil are supplied with an alternating voltage of the same frequency and that the magnetic flux generated by the at least one further transmitting coil is directed opposite to the magnetic fluxes generated by the transmitting coils.
The inventive sensor device for detecting a wheel moving along a rail thus has two transmitting coils on the one side of the rail which are supplied with an alternating voltage and are arranged one behind the other with respect to a longitudinal direction of the rail. Here the wording arranged one behind the other also in principle includes a partially overlapping arrangement of the transmitting coils. This means that the wording arranged one behind the other essentially relates to the respective longitudinal coil axis or coil center. Preferably, however, the transmitting coils are arranged one behind the other in the longitudinal direction of the rail such that they are spaced apart from one another in a non-overlapping manner.
PCT/EP2016/Ο 62141 / 2015P11441WO
On the other side of the rail, the sensor device has two receiving devices with two receiving coils in each case which are connected to one another in series in opposite directions. Here, the receiving coils are also in each case arranged one behind the other with respect to the longitudinal direction of the rail, wherein according to the above note a partially overlapping arrangement is also possible here in principle in the context of the transmitting coils.
The inventive sensor device is now distinguished by the fact that it has at least one further transmitting coil, which is arranged between the transmitting coils with respect to the longitudinal direction of the rail, on the one side of the rail, that is to say on the side on which the two transmitting coils are also arranged. Here, the transmitting coils and the at least one further transmitting coil are supplied with an alternating voltage of the same frequency, wherein, however, the magnetic flux generated by the at least one further transmitting coil is directed opposite to the magnetic fluxes generated by the transmitting coils. This means that the further transmitting coil and the transmitting coils oscillate at the same frequency, but have different phase angles with regard to their magnetic fluxes. Here, the phase difference amounts to 180°, that is to say the further transmitting coil arranged between the transmitting coils has an opposite magnetic field polarity compared to the two transmitting coils. This can be achieved, on the one hand, by an alternating voltage with a phase shifted by 180° compared to the transmitting coils being applied to the further transmitting coil. On the other hand, it is also possible for the further transmitting coil to differ from the transmitting coils with regard to its direction of winding, whereby, when an alternating voltage with the same phase angle is applied,
PCT/EP2016/Ο 62141 / 2015P11441WO magnetic fluxes directed oppositely likewise arise.
It should be noted that the inventive sensor device, for example for symmetry or potential-isolation reasons, can also have two or more separate further transmitting coils of the same phase angle arranged between the transmitting coils.
The inventive sensor device is advantageous since the further transmitting coil leads to an increase in the signal overlapping of the two receiving devices. This is specifically advantageous with small arising signal levels and increases the reliability of a detection of a direction of travel on the basis of the signals detected by the two receiving devices.
On the basis of the fact that the receiving devices have in each case two receiving coils in each case which are connected to one another in series in opposite directions, interference induced from outside is furthermore largely suppressed. The reason for this is that corresponding interference as a rule influences both receiving coils of a receiving device equally. This applies, for example, in relation to rail currents which as a rule have a high level of symmetry with regard to their injection into the receiving coils. Furthermore, the corresponding compensation also acts in relation to magnetic far fields. These could, for example, be caused by adjacent sensor devices, the transmitting magnetic field of which could otherwise lead to resonant beats in the receiving coils.
The fact that the magnetic flux generated by the at least one further transmitting coil is directed opposite to the magnetic fluxes generated by the transmitting coils, together with the connection of the receiving coils of the receiving devices in opposite directions, results furthermore advantageously in the
PCT/EP2016/Ο 62141 / 2015P11441WO effect that in each case both transmitting coils of the receiving devices contribute to the detection of a useful or detection signal. This leads to an increase in the receiving voltages of the receiving devices and therefore finally also to an increase in the sensor sensitivity.
It should be noted that the coils of the inventive sensor device in each case can be constructed from a plurality of partial coils connected in series.
In principle, the transmitting coils, the at least one further transmitting coil and the receiving coils of the inventive sensor device can be arranged in different ways. This applies both with respect to the spacing of the respective coils apart from one another and also with respect to the alignment of the respective coils. In this context it is possible, for example, for the transmitting coils, the at least one further transmitting coil and the receiving coils to be aligned essentially horizontally, perpendicularly to the rail, so that the coil axes point in the direction of the rail. Furthermore, the transmitting coils, the at least one further transmitting coil and/or the receiving coils in each case can also be arranged such that they are tilted toward the rail with respect to the horizontal line and/or the respective perpendicular line. Depending on the respective conditions and requirements, the arrangement and alignment of the coils can be effected in this context in each case such that, between the transmitting coils and the further transmitting coil on the one side and the receiving coils on the other side, a magnetic or inductive coupling ensues, which can be detected by the changing thereof when a wheel moves past it.
Preferably, the inventive sensor device can be developed in
PCT/EP2016/Ο 62141 / 2015P11441WO such a manner that the transmitting coils, the at least one further transmitting coil and the receiving coils are arranged such that, when a wheel moves past the sensor device, a receiving voltage of the same polarity results in each case in the receiving coils of the respective receiving device. This includes the fact that the receiving voltages of the receiving coils of one receiving device are able to have their phase shifted by 180° compared to the receiver voltages of the receiving coils of the other receiving device. For each of the two receiving devices individually, in accordance with the mentioned preferred development of the inventive sensor device, however, the polarity of the receiving voltages is the same as its receiving coils, so that, when forming the sum of the receiving voltages for each of the receiving devices, this results in an increase in the amount of amplitude compared to the receiving voltages of the individual receiving coils of the respective receiving device. To this end, the arrangement and alignment of the coils of the sensor device are selected, for example, such that the outer receiving coils of the receiving devices, when viewed in the longitudinal direction of the rail, are essentially influenced by a respective transmitting coil arranged on the other side of the rail.
Simultaneously, the two inner or center receiving coils of the two receiving devices in the longitudinal direction of the rail are advantageously arranged with respect to the further transmitting coil such that they are principally influenced by the further transmitting coil or the magnetic flux effected thereby. Due to the fact that the magnetic flux of the further transmitting coil is directed opposite to the magnetic fluxes of the transmitting coils, normally a receiving voltage would be induced in the two inner receiving coils in each case hereby, the sign of which is directed opposite to the receiving voltages of the respective outer receiving coil. By
PCT/EP2016/Ο 62141 / 2015P11441WO way of a corresponding connection of the receiving coils of the receiving devices in opposite directions, the sign of the receiving voltages of the center receiving coils inverts, however, so that the receiving voltages of the receiving coils of a receiving device advantageously has the same polarity. This means that both receiving coils of the receiving devices in each case provide a contribution to the signal or receiving voltage of the respective receiving device. As a result, there is thus an increase in the amount of the receiving voltage, whereby advantageously the sensor sensitivity is thus improved.
In accordance with a further particularly preferred form of embodiment of the inventive sensor device, the receiving coils are arranged with the same spacing and the same alignment with respect to the rail. This is advantageous as a particularly effective suppression with respect to interfering magnetic fields, possibly caused by rail currents, results hereby. The fact that corresponding interfering magnetic fields influence the receiving coils connected to one another in series in opposite directions in essentially the same manner and to the same extent, means that there is a best possible compensation of the voltages induced in the two receiving coils of a receiving device as a result.
In accordance with a further particularly preferred development of the inventive sensor device, said device has a generator supplying the transmitting coils and the at least one further transmitting coil. This is advantageous as it can be ensured hereby in a particularly simple and cost-effective manner that the transmitting coils and the at least one further transmitting coil are supplied with an alternating voltage of the same frequency.
PCT/EP2016/Ο 62141 / 2015P11441WO
Advantageously, the inventive sensor device can also be embodied such that the transmitting coils, the at least one further transmitting coil and/or the receiving coils are in each case embodied as a component of a resonant circuit. This is advantageous with regard to a provision of a sufficient magnetic flux, in particularly with respect to the transmitting coils. As a result, the sensor device has a particularly pronounced sensitivity here, whereby finally a particularly reliable detection of wheels is made possible.
Preferably, the inventive sensor device can also be developed such that the transmitting coils, the at least one further transmitting coil and/or the receiving coils are embodied so as to be free from ferromagnetic materials. The embodiment of the respective coils free from ferromagnetic materials offers the advantage that inductive interference effects are reduced or avoided hereby.
In accordance with a further particularly preferred form of embodiment of the inventive sensor device, the transmitting coils and the at least one further transmitting coil are arranged in a shared housing. This results in a particularly simple mechanical embodiment of the sensor device on the transmitter side, combined with advantages during the assembly of the sensor device on or in the region of the rail.
Advantageously, the inventive sensor device can also be developed such that the receiving devices are arranged in a shared housing. According to the above embodiments in conjunction with the transmitting coils as well as the at least one further transmitting coil, the arrangement of the receiving devices in a shared housing also brings advantages
2016287693 10 Jan 2019 with respect to a particularly simple mechanical embodiment of the sensor device as well as with respect to the assembly.
Disclosed herein is a wheel sensor with an inventive sensor device or a sensor device in accordance with one of the aforementioned preferred developments of the inventive sensor device, and also with an evaluation device linked to the receiving devices. Here, the evaluation device can be arranged in the immediate spatial proximity to the receiving devices, that is to say in the track region or in a switch box arranged a relatively short distance away, or even spatially separated from the sensor device in a central control device, perhaps in the form of a signal tower.
In accordance with a particularly preferred embodiment variant of the inventive wheel sensor, the evaluation device is embodied, on the basis of signals of the receiving devices, to carry out a detection of the direction of travel. This is advantageous since wheel sensors are frequently used in conjunction with track vacancy detection devices in the form of axle counters and as a rule a detection of the direction of travel is necessary here.
Disclosed herein is a device for controlling and/or monitoring rail-bound traffic with at least one inventive wheel sensor or at least one wheel sensor in accordance with the aforementioned preferred development of the inventive wheel sensor. Preferably, the inventive device is hereby embodied such that it is a track vacancy detection device. According to the description above, wheel sensors find particular use in conjunction with track vacancy detection devices or with axle counting devices of such track vacancy detection devices.

The invention will now be described in greater detail making reference to exemplary embodiments. In the drawings:
Figure 1

Figure 3 shows a sectional representation of an exemplary embodiment of the inventive sensor device in a first schematic diagram, shows a top view of the exemplary embodiment of the inventive sensor device in a second schematic diagram and shows a further top view of the exemplary embodiment of the inventive sensor device in a third schematic diagram.
In the figures, identical reference characters are used for the same components in each case for reasons of clarity.
Figure 1 shows a sectional representation of an exemplary embodiment of the inventive sensor device in a first schematic diagram. In this Figure, a housing 10 of a transmitter of the sensor device serving to detect a wheel 50 or its wheel flange 51 moving along a rail 60 can be seen. Arranged in the housing 10 of the transmitter which is arranged, by way of example, on the outer side of the rail 60, is a transmitting coil 11, the magnetic field or magnetic flux of which is indicated in
Figure 1 and is designated with the reference character 21. On the other side of the rail 60, that is to say on the rail inner side in the present case, the sensor device comprises a receiver with a housing 30 for detecting the wheel 50 moving along the rail 60, in which housing 30 a receiving coil 32 is arranged corresponding to the sectional representation of
PCT/EP2016/Ο 62141 / 2015P11441WO
Figure 1.
As described in greater detail in conjunction with Figures 2 and 3, in accordance with the described exemplary embodiment of the invention the sensor device has further components which are not shown or cannot be seen in the schematic sectional representation of Figure 1. It is made clear by the representation in Figure 1, however, that the sensor device has a transmitter as well as a receiver, which are arranged on different sides of the rail 60. In this context it should be noted that the housing 10 of the transmitter, as distinct from the representation in Figure 1, naturally can also be arranged at the same height as or lower than the housing 30 of the receiver of the sensor device.
As a precautionary measure, it should be noted that the Figures are exclusively schematic representations. This means in particular that the representations are not to scale and further components, which are known in their own right, have been omitted for reasons of clarity. This relates to brackets, for example, with which the housing 10 of the transmitter of the sensor device as well as the housing 30 of the receiver of the sensor device is mounted or fastened on or in the region of the rail 60.
Figure 2 shows a top view of the exemplary embodiment the inventive sensor device in a second schematic diagram. This makes it clear that the sensor device has two transmitting coils 11 and 12, which are arranged one behind the other with respect to the longitudinal direction of the rail 60. On the other side of the rail 60, the sensor device comprises two receiving devices 31, 35, which have two receiving coils 32 and 33 or 36 and 37, respectively, in each case which are
PCT/EP2016/Ο 62141 / 2015P11441WO connected to one another in opposite directions and are arranged one behind the other with respect to the longitudinal direction of the rail 60. The transmitting coils 11, 12 are supplied with an alternating voltage, whereby magnetic fluxes or magnetic fields 21, 22 ensue, which are suitable for inducing a voltage in the receiving coil 32, 33, 36, 37. By changing the receiving voltages registered on the part of the receiving devices 31, 35 when a wheel moves past, it is hereby possible to detect the wheel in question.
In addition to the mentioned components, the sensor device has a further transmitting coil 13 arranged between the transmitting coils 11, 12 with respect to the longitudinal direction of the rail 60 on the transmitter side, that is to say on the one side of the rail 60 on which the transmitting coils 11, 12 are also arranged. As an alternative, for example, two further transmitting coils could also be provided, which in this case would both be arranged between the transmitting coils 11 and 12, when viewed in the longitudinal direction of the rail 60. Irrespective of whether one further transmitting coil 13 or a plurality of corresponding further transmitting coils is provided, this is (or these are) supplied with an alternating voltage of the same frequency with respect to the transmitting coils 11, 12.
In the representation in Figure 2, however, it is clear that the magnetic flux 23 generated by the at least one further transmitting coil 13 is directed opposite to the magnetic fluxes 21, 22 generated by the transmitting coils 11, 12. This means that the further transmitting coil 13 arranged between the transmitting coils 11, 12 has a magnetic field polarity which is rotated by 180° compared to said two outer transmitting coils 11, 12. In other words, the alternating magnetic field of the further coil 13 has a phase which is
PCT/EP2016/Ο 62141 / 2015P11441WO displaced by 180° compared to the alternating magnetic fields of the transmitting coils 11, 12.
In the context of the described exemplary embodiment, it is assumed that both the transmitting coils 11, 12 and the further transmitting coil 13 are embodied as components of a resonant circuit. Furthermore, the transmitting coil 11, 12, the further transmitting coils 13 as well as the receiving coils 32, 33, 36, 37 are in each case constructed so as to be free from ferromagnetic materials.
Figure 3 shows a further top view of the exemplary embodiment the inventive sensor device in a third schematic diagram. Here, the representation on the transmitter side corresponds to that in Figure 2. On the receiver side, that is to say on the side of the receiving device 31 and 35, the electrical circuit is now, however, indicated in that the receiving coils 32 and 33 of the receiving device 31 are connected to one another in series in opposite directions according to the specified direction of winding and together with a capacitor 34 form a receiving resonant circuit. In a corresponding manner, a receiving resonant circuit is also formed by the receiving coils 36 and 37 of the receiving device 35, together with a capacitor 38.
Furthermore, it can be seen in Figure 3 that the transmitting coils 11, 12, the further transmitting coil 13 as well as the receiving coils 32, 33, 36, 37 are arranged such that the outer receiving coils 32, 37 of the receiving devices 31, 35 in the longitudinal direction of the rail 60 are mainly influenced by the transmitting coil 11 or the transmitting coil 12. The inner receiving coils 33 and 36 in the longitudinal direction of the rail 60, however, are
PCT/EP2016/Ο 62141 / 2015P11441WO principally influenced by the further transmitting coil 13. This is indicated in Figure 3 in the form of a schematic diagram by a behavior of the magnetic or inductive coupling 40 between the transmitting side and receiver side.
The different phase angle of the further transmitting coil 13 compared to the transmitting coils 11 and 12 advantageously induces a voltage of the same polarity in each case in the receiving coils 32, 33 of the receiving device 31 or in the receiving coils 36, 37 of the receiving device 35. Thus, the oppositely directed magnetic flux 23 of the further transmitting coil 13, combined with the connection of the receiving coils 33, 36 to the receiving coils 32 or 37 in opposite directions, especially leads to the receiving coils 32 and 33 or 36 and 37 in each case providing a receiving voltage of the same polarity and in doing so, despite the connection of the receiving coils 32 and 33 or 36 and 37 in opposite directions, compensating for interfering fields, contributing toward the receiving or useful signal of the respective receiving device 31 or 35. The corresponding receiving or signal voltages are designated by the reference characters 41 or 42 in Figure 3. As a result, an increase in the receiving voltages 41, 42 and thus finally a corresponding increase in the sensitivity of the sensor device results from the interaction between the transmitting coils 11, 12, the further transmitting coil 13 and the receiving coils 32, 33, 36, 37.
Furthermore, the structure of the sensor device with the further transmitting coil 13 arranged between the transmitting coils 11, 12 leads to a sufficient signal overlapping between the receiving or signal voltages 41 and 42 of the receiving devices 31 and 35 resulting in all operational situations,
PCT/EP2016/Ο 62141 / 2015P11441WO which is particularly relevant for a detection of a direction of travel. The reasons for this is that when a wheel is in a center position above the sensor device, due to the further transmitting coil 13, a voltage is generated or induced at least in the receiving coils 33 and 36.
Corresponding to the exemplary embodiment described above, the inventive sensor device has the advantage on one side in particular that interference induced from outside is largely suppressed, since this influences both receiving coils 32 and 33 or 36 and 37 of the respective receiving device 31 or 35 equally as a rule. Hereby, a high immunity to interference, in particular with respect to magnetic fields caused by rail currents, results in particular for the preferred case that all receiving coils 32, 33, 36 and 37 have the same spacing and the same alignment with respect to the rail 60.
On the other hand, the arrangement of the at least one further transmitting coil 13 between the transmitting coils 11 and 12, as explained above, advantageously leads to an increase in the signal overlapping of the receiving devices 31 and 35. This is especially advantageous with small signal levels and supports a reliable detection of a direction of travel on the basis of the signals of the receiving devices 31 and 35.
Moreover, according to the description above, both receiving coils 32 and 33 or 36 and 37, respectively, of the receiving devices 31 and 35, which compensate for interfering fields and can also be referred to as receiving channels, contribute to the receiving or useful signal. As a result, this leads to an increase in the receiving voltage and thus to an enhanced verification sensitivity of the sensor device.
