Definitions
- the invention relates to a wheel sensor and a wheel sensor arrangement according to the preamble of the independent claims 1, 3, 8 and 10.
- Wheel sensors are used in railway systems for the Track vacancy detection, but also for other switching and signaling tasks used. It is mainly the magnetic field influencing Effect of the iron wheels of the rail vehicles exploited.
- inductive sensors attached to the track body that generate a specific magnetic field can be Record the retroactive effect of the iron wheels, with each wheel detection a wheel impulse is registered.
- the number of wheel impulses gives in cooperation with one Another wheel sensor provides information about the occupancy of the intermediate one Track section.
- This track vacancy notification represents an essential decision criterion for control of turnouts and signals.
- Frequency selection also cannot avoid that interference fields frequency components in the range of the working frequency of the inductive sensor included. Usually lie the working frequencies in the range from 30 kHz to 1 MHz, while Interference fields can also reach frequencies up to 2 MHz can.
- Another approach is based on compensation efforts the way that the interference magnetic field by building an opposing Field is virtually neutralized.
- the DE-A1-197 09 844 is a coil arrangement with a magnetic Core provided. Two concentrically arranged Coils are switched so that when shared Magnetic fields flow in opposite directions. A magnetic one In contrast, interference field induces interference voltages in both coils, because of the opposite connection of the two Compensate coils.
- the coil assembly is part of one Get inductive sensor for generating a working magnetic field remains. The iron mass of a wheel running over changes the properties of the working magnetic field, what is sensory is recorded.
- Problematic with this approach is, however, that a very strong interference magnetic field, for example that of an excited eddy current brake, the coil core like that can magnetize that an unwanted response of the Sensor is caused.
- a similar but coreless coil arrangement is from the DE-A1-199 15 597 known.
- the sensitivity of this generic Axle counter is low, however, because of the detection magnetic field of the wheel created the area of the flange of the wheel does not penetrate optimally. Besides, can Wetness on the sensor housing at the usually high working frequencies coreless coil arrangements for a further reduction sensor sensitivity.
- the object of the invention is to overcome these disadvantages eliminate and specify a wheel sensor with inductive sensor, its parameters in terms of sensitivity and thus with regard to the reliability of the overall system are optimized.
- the second coil is preferably centric according to claim 2 arranged within the first coil.
- the compensation effect is however also present when the inner coil is arranged eccentrically.
- the coil shapes can also be very be different.
- the inner coil have circular turns and eccentric within an oval outer coil.
- Claim 3 characterizes a further solution to the problem, where compared to the solution according to claim 1 additionally simplification is achieved. Coils of different Geometry and different numbers of turns are included this alternative solution is not required. Instead it is an overlapping arrangement in the vertical projection similar coils are provided, the winding planes are virtually arranged one above the other. Because the coils are not in each other or are arranged penetrating the magnetic field generated by one coil closes the other coil equal parts with opposite inner and outer magnetic fluxes, that is, the coils are magnetic decoupled from each other.
- the coils are preferably very flat, spiral wound disc coils. To this The coils can be easily inserted into the housing Install the wheel sensor.
- the winding planes of the coils both alternative solutions run parallel to the track level.
- both Coils with the same angle of inclination to a horizontal surface tilted in the direction of the track. Magnetic interference fields then pass through both coils with the same intensity and Direction and cancel each other out even if the field is not runs parallel to the coil longitudinal axes.
- two wheel sensors are arranged one behind the other. On this can be done based on the time interval between the Wheel pulse registration the direction of travel of one of the two Determine the wheel sensors of a rolling rail vehicle.
- Claim 10 characterizes a dual wheel sensor arrangement, in which there are also the adjacent coils of the two wheel sensors overlap.
- the magnetic one also works in this area Decoupling according to claim 3.
- the advantage of this arrangement is that the geometric overlap of the Wheel sensors have a longer overlap phase of one wheel has influence exerted on both sensors.
- FIG. 1 schematically illustrates the operation of an inductive sensor with interference field compensation according to the prior art.
- the sensor essentially consists of an oscillator 1 and an oscillating circuit 2 with a capacitor C and two coils L1 and L2.
- the interference voltages U StörL1 and U StörL2 of an interference magnetic field ⁇ s acting in the same way on both coils L1 and L2 (FIG. 2 and FIG. 5).
- the two coils L1 and L2 in the LC resonant circuit 2 are connected in such a way that the interference voltages U StörL1 and U StörL2 are opposed at the same absolute value and thus cancel each other out.
- a working voltage U oszL1 or U oszL2 applied by the oscillator 1 to the LC oscillating circuit 2 for generating a working magnetic field is hardly influenced by this arrangement.
- Figure 2 shows a track body 3 in perspective view with a first embodiment of a coil arrangement according to the invention for interference magnetic field compensation. It is seen that a noise magnetic field ⁇ s of a rail current I s is generated.
- the two coils L1 and L2 connected in series are designed as the inner coil Li and the outer coil La, the winding orientations of the two coils Li and La being opposed to one another, as shown in FIGS. 3a and 4 Arrows symbolize point.
- the number of turns n Li of the inner coil Li is greater than the number of turns n La of the outer coil La.
- the compensation effect is also present if, as in Figure 4, the inner coil Li is not centered in the outer Coil La is arranged.
- the Coils Li and La almost any shape, such as circular, have square, rectangular or oval.
- Figures 5 to 10 relate to another invention Embodiment of an interference field compensating Coil assembly. Compared to that shown in Figures 2 to 4 Variant differs from this embodiment in particular in that the coils used L1 and L2 in contrast to the coils Li and La of the same geometry exhibit. This results in a reduction in effort or the cost.
- Figure 5 shows in an analogous representation to Figure 2 that two mutually offset and partially overlapping coils L1 and L2 of the same geometry and number of turns are provided. Since both coils L1 and L2 are identical, the same disturbing voltage U and U StörL1 StörL2 induces the disturbance magnetic field ⁇ s in both coils L1 and L2 ( Figure 1). For compensation, the coils L1 and L2 are connected to one another, as explained for FIG. 1.
- Each coil L1 and L2 generates a magnetic field like an individual coil, since there is no mutual interference due to the magnetic decoupling. It therefore has no influence that the magnetic fields B L1 and B L2 of both coils L1 and L2 are opposite in the oscillator mode. Both coils L1 and L2 contribute equally to the detection of a wheel because their magnetic fields B L1 and B L2 are influenced in the same way by the flange 4 (FIG. 8) of a wheel. Compared to an arrangement with only one sensor coil, that is to say without including this individual coil in a coil majority for interference field compensation, the effective range of the wheel is extended approximately by the lateral offset X of the two coils L1 and L2.
- Figure 8 shows the coils L1_1, L2_1 and L2_2 of two wheel sensors relative to the track body 3.
- the coils are L1_1, L2_1 as well as L2_2 and L1_2 in this way, for example within one Sensor housing, attached that their centers are constant Height to the horizontal base of the track body 3 have, the winding planes inclined to the track level are.
- Magnetic interference fields then penetrate the two coils L1_1 and L2_1 or L2_2 and L1_2 each with the same intensity and direction and cancel each other out, even if that Interference field does not run parallel to the coil longitudinal axes.
- the double sensor shown in Figure 8 is from the wheel flange 4 of the wheel in a certain chronological order run over so that from the signal order to the direction of travel of the rail vehicle can be closed.
- FIG. 9 shows a preferred coil shape for wheel sensors shown.
- the coils L1 and L2 are disc-shaped and wrapped in spirals.
- the height of the disc coils corresponds to the diameter of the winding wire and is consequently so small that the two overlapping coils L1 and L2 built into the housing of a wheel sensor without inclination can be.
- Figure 10 illustrates a double sensor with disc coils L1_Sys1 and L2_Sys1 as well as L1_Sys1 and L2_Sys2, where also the adjacent coils L2_Sys1 and L1_Sys2 of the two Sensor systems Sys1 and Sys2 overlap

ULi = ULa ergibt sich für die Dimensionierung der Spulen:
bedeuten. Die innere Spule Li hat also eine dem Flächenverhältnis entsprechende höhere Windungszahl nLi als die äußere Spule La. Dieser Umstand hat zur Folge, dass die durch den Schwingkreisstrom des Oszillators 1 in beiden Spulen Li und La entgegengesetzt auftretenden Induktionen BLi und BLa nicht gleich groß sind und im Bereich der inneren Spule Li gemäß Figur 3a eine ausreichend hohe Gesamtinduktion BLi-BLa zur Detektion eines den induktiven Sensor überfahrenden Rades eines Schienenfahrzeuges verbleibt. Dagegen kompensieren sich der innere und der äußere Anteil eines Störmagnetfeldes mit der Gesamtinduktion BStör gegenseitig, wie Figur 3b in symbolhafter Darstellung zeigt.
