Definitions

  • the invention relates to a method and a magnetic sensor for the magnetic testing of valuable documents.
  • Valuable documents generally have various security features to make them more difficult to forge or which are specific to the respective type of valuable document.
  • the authenticity of a document of value or the type of document of value is checked using special testing devices which include a detector arrangement and a transport device which guides the document of value past the detector arrangement.
  • the detector arrangement determines measured values at many measuring points on the surface of the valuable document that represent certain properties of its security features. The measured values determined are then used to check the authenticity of the document and compared, for example, with reference values.
  • the measured values can be distorted because the distance between the document of value and the detector fluctuates. This connection is usually such that the measurement signal decreases as the distance between the detector and the measuring point increases. This distance can not only change from one document of value to the next, but can also change within a document of value, so that measuring points of the same document of value that are checked one after the other occupy different distances from the detector. This varying distance is caused, for example, by bends and corrugations of the document, especially in used banknotes, or by the fluttering of the valuable documents when they are passed quickly through the testing device.
  • the distance dependence of the magnetic measurement signal is particularly noticeable when the document of value is at a small distance from the detector.
  • the WO2004/055739 A1 discloses two individual inductive sensor elements that are arranged on opposite sides of the transport path of a document of value, so that the documents of value are transported between the two inductive sensor elements.
  • the document of value is transported past a magnetic sensor along a transport direction.
  • the magnetic sensor has, transverse to the transport direction of the valuable document, i.e. perpendicular or oblique to the transport direction of the valuable document, a measuring sensor line with a plurality of magnetosensitive measuring sensor elements, which are arranged at a target distance from a transport plane of the valuable document.
  • the magnetic sensor has at least one further magnetosensitive sensor element, preferably at least two further magnetosensitive sensor elements, which, viewed from the document of value being transported past, is/are arranged behind the measuring sensor line along a line parallel to the measuring sensor elements and a larger one Distance from the transport plane of the document of value has/s than the measuring sensor elements.
  • the magnetosensitive measuring sensor elements and the magnetosensitive further sensor element(s) are referred to below simply as measuring sensor elements and further sensor elements.
  • the measuring sensor elements detect measurement signals of the document of value at several measuring points of the document of value, which are arranged on the document of value along a measuring line transverse to the transport direction.
  • the further sensor element(s) detect(s) a correction signal(s) at a respective correction measuring point of the value document, which lies on the same measuring line(s) as the measuring points.
  • the measurement signals detected at the measuring points are measured using the at the Correction measuring point/s detected correction signal/s corrected.
  • the measurement signals from the measuring points corrected in this way are used to check the magnetic properties of the document of value.
  • the correction signals of the correction measuring points are preferably detected simultaneously with the measuring signals of the measuring points in order to be able to carry out the distance correction as accurately as possible.
  • the respective measurement signal is compared with the respective correction signal. Due to the greater distance of the at least one further sensor element from the document of value compared to the measuring sensor elements, the correction signal is lower than the measuring signal of the respective measuring point.
  • the respective measurement signal of the respective measuring point is corrected based on the signal drop that the correction signal determined for this measuring point has in comparison to the measurement signal of the respective measuring point.
  • a correction signal can be determined for the respective measuring point of the measuring line at which the measuring sensor elements have detected the respective measuring signal.
  • the expression "correction signal determined for the measuring point” includes the case that the correction measuring point and the measuring point on the value document are identical, but also includes the case that the correction measuring points are not identical to the measuring points, but rather the measuring signal of a measuring point using the /the correction signal(s) of one/several correction measuring point(s) adjacent to the respective measuring point, for example the closest one on the document of value, is corrected.
  • the correction signal from another sensor element is used, for example, to correct the measurement signals from several measuring points that are in the vicinity of the correction measuring point of this further sensor element.
  • the respective measurement signal of a measurement point is compared with the correction signal determined for this measurement point, for example by calculating the ratio of the correction signal and the measurement signal. Based on the signal drop that the correction signal determined for this measuring point has in comparison to the measuring signal of the respective measuring point (e.g. based on the ratio between the measuring signal of the respective measuring point and the correction signal determined for this measuring point), the (local) distance of the respective measuring point is then determined Value document is calculated by the respective measuring sensor element. With the help of the determined (local) distance of the value document from the measurement sensor element, the respective measurement signal that the respective measurement sensor element has detected at the respective measurement point is corrected, in particular with the aid of a known distance dependence of the measurement signal. The corrected measurement signal of the respective measuring point is determined, for example, by inserting the distance determined for the respective measuring point into the distance dependence of the measurement signal determined in advance of the value document inspection.
  • the correction is carried out qualitatively in such a way that the measurement signal of the measuring sensor elements is corrected upwards if the determined distance exceeds the target distance that the transport plane of the document of value has to the measuring sensor elements, and is corrected downwards if the determined distance is Target distance falls below.
  • the size of this correction depends on the ratio of the respective measurement signal of a measuring point to the correction signal determined for this measuring point.
  • the corrected measurement signal corresponds, for example, to the measurement signal that comes from the measurement sensor elements would be detected at the target distance of the value document from the measuring sensor elements.
  • the distance dependence mentioned can, for example, be known from a data sheet of the measuring sensor elements or have been determined based on its data. However, it can also have been simulated or determined empirically in advance of the value document check for the measuring sensor elements. For example, in advance of the value document check, a distance dependency is determined for the measurement sensor elements of the magnetic sensor, which reflects the course of the measurement signal of the measurement sensor elements as a function of the distance between the value document and the measurement sensor elements. In the same way, a (further) distance dependence is determined for the at least one further sensor element, which reflects the course of the correction signal as a function of the distance between the document of value and the measuring sensor elements. For example, the dependence of the distance on the relationship between the correction signal and the measurement signal is determined from the course of the measurement signal and the course of the correction signal as a function of the distance.
  • the determined distance is a local distance in that it is only valid individually for the respective measuring point, with the distances determined for different measuring points normally differing from one another.
  • the individual distance determined for the respective measuring point can be inserted into the known distance dependence of the measurement signal in order to determine a correction factor that applies individually to the respective measuring point, which is offset against the measurement signal of the respective measuring point. Accordingly, the correction factor for the respective measuring point is individual, with the correction factors being different for the different measuring points usually differentiate from each other.
  • the corrected measurement signal of the respective measuring point can be determined by inserting the distance of the measuring point determined for the respective measuring point into the known distance dependence of the measurement signal of the measuring sensor elements, for example determined in advance of the value document check, in order to obtain a distance dependence that applies individually to the respective measuring point Determine correction factor.
  • the respective measurement signal of the respective measuring point can then be multiplied by the correction factor determined for the respective measuring point in order to obtain the corrected measurement signal.
  • the ratio between the respective correction signal and the respective measurement signal is preferably formed. From the relationship between the respective correction signal and the respective measurement signal, the distance of the respective measuring point of the document of value from the respective measuring sensor element is determined with the aid of the known distance dependence of the ratio. From this distance, which was determined individually for the respective measuring point of the document of value, a local correction factor is determined for the respective measuring point of the document of value. To correct the measurement signal, the measurement signal of the respective measuring point is offset (e.g. multiplied or divided) with the respective local correction factor that was determined for the respective measuring point. However, the correction of the detected measurement signal is preferably only carried out for those measurement signals of the security element to be tested that reach or exceed a predetermined threshold.
  • the number of further sensor elements is preferably smaller than the number of measuring sensor elements, in particular smaller by at least a factor of 2.
  • the measuring sensor elements can be arranged regularly at 2mm intervals from one another and the other sensor elements at 10mm intervals from one another. It was recognized that the distance of the valuable document from the magnetic sensor usually only changes significantly over a length of several mm (viewed perpendicular to the transport direction). Due to the smaller number of correction sensor elements compared to the measuring sensor elements, distance correction is possible with less effort.
  • the measurement signal of those measurement sensor elements that lie along the measurement line between two of the further sensor elements can be corrected using the correction signals of the further sensor elements that are closest to these measuring elements.
  • the density of the further sensor elements of the magnetic sensor in the direction perpendicular to the transport direction of the valuable document is selected such that the magnetic sensor has at least one further sensor element for each 20 mm section of the valuable document perpendicular to the transport direction of the valuable document.
  • the number of additional sensor elements is thus adapted to the characteristic length perpendicular to the transport direction, to which the distance of the document of value from the magnetic sensor changes.
  • the measurement signal of the measurement points of such measurement sensor elements, behind which no further sensor element is arranged is preferably corrected with the help of the correction signals from at least two correction measurement points.
  • the correction signals of the other sensor elements or values derived from these correction signals e.g. the distance
  • the correction signal itself is interpolated and then used to correct the measurement signals of the measurement sensor elements in between.
  • a fit of the correction signals of these measuring points in the case of more than two correction measuring points, in particular a polynomial fit
  • a correction signal can thus be generated for those measuring sensor elements behind which no further sensor element is arranged.
  • the local distance of the correction measuring points of the value document from the measuring sensor elements can first be determined from the correction signal and then, by interpolating the distance values, the local distance can also be determined for the measuring sensor elements in between (behind which no further sensor element is arranged). of the document of value can be determined.
  • the measurement signals are detected from measuring points of a two-dimensional section (ROI) of the document of value, which extends both vertically and along the transport direction.
  • the measurement signals of the Measuring points of this two-dimensional section (ROI) are preferably compared with a minimum value.
  • the minimum value is, for example, higher than the threshold mentioned above (below which the measurement signal is ignored).
  • the measurement signal of such a measurement point is corrected by the correction signal detected at the respective measurement point or at the nearest adjacent correction measurement point.
  • the measurement signal of such a measurement point whose measurement signal falls below the minimum value (but exceeds the above-mentioned threshold)
  • Their correction signals are interpolated to determine an interpolated correction signal for the respective measuring point.
  • the correction signals of at least two correction measuring points of this two-dimensional section are interpolated, which are offset along the transport direction to the respective measuring point.
  • one of the correction measuring points - viewed in the transport direction of the valuable document - is selected at the beginning of the ROI and another correction measuring point at the end of the ROI.
  • the interpolation of several correction signals in the case of low measurement signals has the advantage that even small measurement values are taken into account for testing the two-dimensional security element, but their (incorrect) correction with a single, very small correction measurement value that is detected for this measurement point is avoided.
  • one or more further correction measuring points of this two-dimensional section (ROI) which are offset perpendicularly or obliquely to the transport direction to the respective measuring point, can also be used for the interpolation.
  • an average distance of the two-dimensional section (ROI) from the measuring sensor elements can be determined, which is valid for the two-dimensional section (ROI) as a whole. Then the measurement signals of all measurement points of this two-dimensional section (ROI) can be corrected using this average distance of the two-dimensional section (ROI).
  • the invention also relates to a magnetic sensor for checking the magnetic properties of the document of value.
  • the magnetic sensor contains the above-mentioned measuring sensor line, which has a plurality of magnetosensitive measuring sensor elements arranged at a target distance from the transport plane of the document of value, and the further magnetosensitive sensor element(s) in relation to the document of value being transported past , is/are arranged behind the measuring sensor line along a line parallel to the measuring sensor elements and is/are at a greater distance from the transport plane of the document of value than the measuring sensor elements.
  • the measuring sensor elements and the at least one further sensor element are arranged on the opposite sides of the same carrier. Since their distance from each other is determined particularly precisely, the distance correction is also more precise.
  • the measuring sensor elements and the at least one further sensor element preferably use the same measuring principle. Since they use the same measuring principle, all magnetic influences, such as magnetic field disturbances, which influence the measuring signal of the measuring sensor elements, have a similar effect on the measuring signal of the other sensor element(s). There If magnetic interference affects both in the same way, a particularly precise distance correction can be achieved with the additional sensor element(s) that use the same measuring principle.
  • the measuring sensor elements and the further sensor element(s) are preferably identical in construction. The measurement signals of the measurement sensor elements and the other sensor element(s) are then only different due to the different distance from the document of value. This enables a particularly precise correction of the distance dependence.
  • the magnetic sensor contains a control device which is set up to control the measuring sensor line in such a way that the measuring sensor elements detect measurement signals of the valuable document at several measuring points on the valuable document, which are arranged along a measuring line transverse to the transport direction on the valuable document, and that / to control the other sensor element(s) so that they detect a correction signal at the respective correction measuring point of the document of value, which lies on the same measuring line.
  • the control device controls the measuring sensor line and the further sensor element(s) according to the method described above and has corresponding software to carry out the method described above.
  • the magnetic sensor has an evaluation device which is set up to correct the measurement signals detected at the measuring points of the document of value with the aid of the correction signal(s) detected at the correction measuring point(s) of the document of value, in order to thereby reduce the distance dependence of the measurement signals to calculate it out and to check the value document on the basis of the corrected measurement signals from several of the measurement points.
  • the evaluation device can be housed in the housing of the magnetic sensor, but it can also be arranged outside of it be.
  • the evaluation device and the control device can be combined in one device.
  • the evaluation device is set up to evaluate the detected measurement signals and correction signals according to the method described above and has corresponding software for this purpose.
  • the evaluation software carries out the distance correction described and checks the magnetic properties of the valuable document.
  • the invention also relates to a device for testing the magnetic properties of a document of value.
  • This can be a valuable document processing device, in particular a checking device or a sorting device for valuable documents, or an input or Payout device for documents of value.
  • the device has the magnetic sensor described above, as well as possibly also other sensors, and a transport device for transporting the document of value in the transport plane along a transport direction, which transports the documents of value to be checked past the magnetic sensor one after the other.

  • one and the same further sensor element 8 can be used to correct the measurement signal of several measuring sensor elements 7, ie several measuring points on the value document can be used.
  • the correction signal of the respective further sensor element 8 is assigned to the measurement signals of those measuring sensor elements 7 which are arranged closest to the respective further sensor element along the y-direction.
  • Figure 2 shows schematically a magnetic sensor 10 of a device for processing valuable documents, into which the valuable documents 1 are entered individually or in batches, then checked, sorted and stored in the device for processing valuable documents or output again.
  • a document of value 1 is transported along a transport path first past a magnetization device, which provides a magnetic field A, and then past a magnetic sensor 10 with two sensor lines 12, 14. Depending on the requirements of the magnetic sensor, it can alternatively have only one of the two sensor lines 12, 14.
  • the magnetic field A magnetizes high and low coercive magnetic areas of the document of value 1. For example, the magnetic field A in Transport direction T of the valuable document 1.
  • the magnetic field A can also include several sections with different magnetic field directions.
  • the magnetic field A can be provided, for example, by two magnets lying opposite one another, between which the document of value 1 is transported and whose magnetic north poles N point towards one another, so that a magnetic field A parallel to the transport direction T results between them.
  • another pair of magnets can also be used, in which the two magnetic south poles point towards each other, for example to achieve anti-parallel magnetization of low-coercivity magnetic areas.
  • only a magnet arranged on one side of the transport path can be used for magnetization, as long as a sufficiently large magnetic field strength is achieved to magnetize the document of value.
  • the first magnetic field A can also be provided by just a single bar magnet or by a horseshoe magnet analogous to magnet 18.
  • the document of value 1 has a security element 2 with magnetic coding.
