Definitions
- the invention relates to a method and a magnetic sensor for magnetic testing of value documents.
- Value documents generally have various security features to make their forgery more difficult or specific to the particular value document type.
- the authenticity of a value document or the value document type is checked with special testing devices, which comprise a detector arrangement and a transport device, which passes the value document past the detector arrangement.
- the detector arrangement determines measured values which represent certain properties of its security features.
- the measured values obtained are then used to check the authenticity of the document, for example by compared with reference values.
- the measured values can be falsified by the fact that the distance between the document of value and the detector fluctuates. Usually, this relationship is such that the measuring signal decreases with increasing distance between detector and measuring point.
- This distance can not only change from one value document to the next, but can also change within a value document, so that consecutively tested measuring points of the same value document occupy different distances from the detector.
- This varying distance is caused, for example, by kinking and curling of the document, in particular in the case of used banknotes, or else by fluttering of the value documents during rapid passage through the test apparatus.
- the value document is transported past a magnetic sensor along a transport direction.
- the magnetic sensor has, transversely to the transport direction of the value document, i. perpendicular or oblique to the transport direction of the value document, a measuring sensor line with a plurality of magneto-sensitive measuring sensor elements, which are arranged at a desired distance to a transport plane of the value document.
- the magnetic sensor has at least one further magneto-sensitive sensor element, preferably at least two further magneto-sensitive sensor elements, which is / are arranged behind the measuring sensor line along a line parallel to the measuring sensor elements, viewed from the value document transported past, and a larger one Distance from the transport plane of the value document has / s as the measuring sensor elements.
- the magneto-sensitive measuring sensor elements and the magneto-sensitive further sensor element (s) will be referred to below simply as measuring sensor elements and further sensor elements.
- measuring signals of the value document are detected at a plurality of measuring points of the value document, which are arranged along a measuring line on the value document transversely to the transport direction.
- a correction signal is respectively detected at a respective correction measuring point of the value document, which lies on the same measuring line as the measuring points.
- the measuring signals detected at the measuring points are detected with the help of the / on Correction measurement point / s detected correction signal / e corrected.
- the measuring signals of the measuring points corrected in this way are used for checking the magnetic properties of the value document.
- the correction signals of the correction measurement points are detected simultaneously with the measurement signals of the measurement points in order to be able to perform the most accurate distance correction 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 value document in comparison to the measuring sensor elements, the correction signal is lower than the measurement signal of the respective measuring point.
- the respective measuring signal of the respective measuring point is corrected on the basis of the signal drop which the correction signal determined for this measuring point has in comparison to the measuring signal of the respective measuring point.
- a correction signal can be determined for the respective measurement point of the measurement line at which the measurement sensor elements have detected the respective measurement signal.
- the expression "correction signal determined for the measurement point” includes the case that the correction measurement point and the measurement point on the value document are identical, but also includes the case that the correction measurement points are not identical with the measurement points, but the measurement signal of a measurement point using the The correction signal of a further sensor element is used eg to correct the measurement signals for a plurality of measurement points which are close to the correction -Messiges clieses further sensor element lie.
- the respective measuring signal of a measuring point is compared with the correction signal determined for this measuring point, e.g. by calculating the ratio of correction signal and measurement signal.
- the (local) distance of the respective measuring point of the Value document calculated by the respective measuring sensor element.
- the respective measuring signal which the respective measuring sensor element has detected at the respective measuring point is corrected, in particular with the aid of a known distance dependence of the measuring signal.
- the corrected measurement signal of the respective measurement point is e.g. determined by the distance determined for the respective measuring point being used in the distance dependence of the measuring signal determined in advance of the value-document check.
- the correction is carried out qualitatively such that the measuring signal of the measuring sensor elements is corrected upward if the determined distance exceeds the nominal distance, which the transport plane of the document of value has to the measuring sensor elements, and is corrected downward, if the determined distance Specified distance below.
- the size of this correction depends on the ratio of the respective measurement signal of a measurement point to the correction signal determined for this measurement point.
- the corrected measuring signal corresponds, for example, to the measuring signal which is emitted by the measuring Sensor elements in the desired distance of the value document would be detected by the measuring sensor dementen.
- the mentioned distance dependence may be known, for example, from a data sheet of the measuring sensor elements or may have been determined on the basis of the data thereof. However, it can also be simulated in advance of the value document check for the measuring sensor elements or determined empirically. For example, a distance dependence is determined in advance of the value document check for the measuring sensor elements of the magnetic sensor, which shows the course of the measuring signal of the measuring sensor elements as a function of the distance between the value document and the measuring sensor elements. In the same way, a (further) distance dependence is determined for the at least one further sensor element which reproduces the profile of the correction signal as a function of the distance between the value document and the measuring sensor elements.
- the dependence of the distance on the ratio 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 insofar as it is valid only individually for the respective measuring point, wherein the distances determined for different measuring points normally differ from one another.
- the individual distance determined for the respective measurement 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 measurement point and is offset with the measurement signal of the respective measurement point.
- the correction factor for the respective measuring point is also individual, whereby the correction factors for the different measuring points usually different from each other.
- the corrected measuring signal of the respective measuring point can be determined by the distance, determined for the respective measuring point, of the measuring point from the known, e.g. determined in advance of the value document test, distance dependence of the measuring signal of the measuring sensor elements is used to determine an individually applicable for the respective measuring point correction factor.
- the respective measuring 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 measuring 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 measurement point of the value document from the respective measurement 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 value document, a local correction factor is determined for the respective measuring point of the value document. To correct the measuring signal, the measuring signal of the respective measuring point is calculated (eg multiplied or divided) with the respective local correction factor, which was determined for the respective measuring point. However, the correction of the detected measurement signal is preferably carried out only for those measurement signals of the security element to be tested which 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 regularly arranged at 2 mm intervals away from each other and the other sensor elements in 10mm intervals from each other. It has namely been recognized that the value-document distance from the magnetic sensor usually changes significantly only to a length of several mm (viewed perpendicularly to the transport direction). Due to the smaller number of correction sensor elements compared to the measuring sensor elements, a distance correction with less effort is possible. The measurement signal of those measuring sensor elements which lie along the measuring line between two of the further sensor elements can be corrected with the aid of the correction signals of the further adjacent sensor elements 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 value document is selected such that the magnetic sensor has at least one further sensor element for every 20 mm section of the value document perpendicular to the transport direction of the value document.
- the number of further sensor elements is adapted to the characteristic length perpendicular to the transport direction, to which the distance of the value document from the magnetic sensor changes.
- the measurement signal of the measuring points of such measuring sensor elements, behind which no further sensor element is arranged, is preferably corrected by means of the correction signals of at least two correction measuring points.
- the correction signals of the further sensor elements or values derived from these correction signals can be interpolated (interpolation in the y direction).
- the correction signal itself is interpolated and then used to correct the measurement signals of the intermediate measurement sensor elements.
- 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 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, also for the intermediate measuring sensor elements (behind which no further sensor element is arranged) local distance of the value document can be determined.
- the measurement signals of measurement points of a two-dimensional segment (ROI) of the value document are detected during the transport of the value document, which extends both vertically and along the transport direction.
- the measuring signals of the 8 000080 are also preferred.
- Measurement points of this two-dimensional segment are preferably compared to a minimum value.
- the minimum value is higher than the above threshold (below which the measurement signal is ignored).
- the measurement signal of such a measurement point whose measurement signal reaches or exceeds the minimum value is corrected by the correction signal detected at the respective measurement point or at the next adjacent correction measurement point.
- the measurement signal of such a measurement point whose measurement signal falls below the minimum value is corrected by means of the correction signals of at least two, preferably at least three, correction measurement points of this two-dimensional segment (ROI).
- 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 measurement points - viewed in the transport direction of the value document - is selected at the beginning of the ROI and another correction measurement point at the end of the ROI.
- the interpolation of a plurality of correction signals in the case of small measurement signals has the advantage that even low measured values are taken into account for testing the two-dimensional security element, but its (incorrect) correction is avoided with a single very small correction measurement value which is detected for these measurement points.
- one or more further correction measuring points of this two-dimensional section (ROI) can be used for the interpolation, which are offset perpendicularly or obliquely to the transport direction to the respective measuring point. From the correction signals of two or more than two correction measuring points, an average distance of the two-dimensional section (ROI) from the measuring sensor elements that is valid for the two-dimensional section (ROI) as a whole can be determined. Then, the measurement signals of all measurement points of this two-dimensional segment (ROI) can be corrected with the help of this mean distance of the two-dimensional segment (ROI).
- the invention also relates to a magnetic sensor for testing magnetic properties of the value document.
- the magnetic sensor contains the above-mentioned measuring sensor line, which has a plurality of magneto-sensitive measuring sensor elements arranged at a desired distance from the transport plane of the value document, and the other magneto-sensitive sensor element or elements, with reference to the document of value conveyed past , is arranged behind the measuring sensor line along a line parallel to the measuring sensor elements / and have a greater distance from the transport plane of the value document / s 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 particularly well defined, the distance correction is more accurate.
- the measuring sensor elements and the at least one further sensor element preferably use the same measuring principle. Since these use the same measuring principle, all magnetic influences, such as magnetic field disturbances, which influence the measuring signal of the measuring sensor elements, similarly affect the measuring signal of the further sensor element (s). There If magnetic interferences affect both in the same way, a particularly accurate distance correction can be achieved with the / further sensor element (s) which use the same measuring principle.
- the measuring sensor elements and the / the further sensor element / s construction are the same. The measuring signals of the measuring sensor elements and the / the further sensor element / s are then different only because of the different distance to the value document. This allows a particularly accurate correction of the distance dependence.
