Abstract

According to the invention, the sensors of a banknote processing device are function tested, adjusted and/or calibrated using testing media that have specific characteristics for testing, adjusting and/or calibrating individual or several sensors. Said specific characteristics can only be recognized and differentiated by the banknote processing device by means of a machine readable identification. For each identification, information regarding which characteristic of which sensor is to be checked, adjusted and/or calibrated on the basis of the testing medium is stored in the valuable document processing device. Furthermore, the sensor measured values concretely determined during test runs are compared with sensor measured values that were determined in prior test runs and/or during initial operation of the banknote processing device in order to determine a trend in the properties of the sensor and to timely exchange said sensor.

Justierung und/ oder Kalibrierung der Wertdokumentbearbeitungs- vorrichtung und Testmedien zur Durchführung des VerfahrensAdjustment and / or calibration of the document processing device and test media for performing the method
Die Erfindung betrifft ein Verfahren zur Funktionsprüfung, Justierung und/ oder Kalibrierung von mindestens einem Sensor in einer Wertdoku- mentbearbeitungsvorrichtung und eine entsprechende Wertdokumentbear- beitungsvorrichtung sowie geeignete Testmedien zur Durchführung des Verfahrens.The invention relates to a method for functional testing, adjustment and / or calibration of at least one sensor in a value document processing device and a corresponding value document processing device as well as suitable test media for carrying out the method.
Wertdokumentbearbeitungsvorrichtungen werden insbesondere zur Bearbeitung von Banknoten benötigt, um beispielsweise Banknoten auf spezielle Echtheitsmerkmale und Qualitätseigenschaften zu prüfen. Fälschungen und durch Gebrauch verschlissene Banknoten werden aussortiert. Wertdoku- mentbearbeitungsvorrichrungen sind grundsätzlich auch zur Prüfung jeder anderen Art von Wertdokumenten verwendbar, beispielsweise zur Prüfung von Ausweisen, Kreditkarten, Scheckkarten, Fahrausweisen und dergleichen.Valuable document processing devices are required in particular for processing banknotes, for example to check banknotes for special authenticity features and quality properties. Counterfeits and banknotes worn out by use are sorted out. Fundamentals for processing documents of value can in principle also be used for checking any other type of documents of value, for example for checking ID cards, credit cards, check cards, travel tickets and the like.
Die Prüfung der Wertdokumente erfolgt mittels mehreren, je nach der zu prüfenden Wertdokumenteigenschaft unterschiedlichen Sensoren. Die Sensoren werden in zeitlichen Abständen bezüglich ihrer korrekten Funktionsfähigkeit, Justierung und/ oder Kalibrierung überprüft. Diese Überprüfung erfolgt üblicherweise mittels spezieller Testmedien. "Testmedien" im Sinne der vorliegenden Erfindung sind nur solche lauffähigen Funktionsprüf-, Justier- und/ oder Kalibrierhilfsmittel, die speziell präpariert sind, also beispielsweise speziell für die Überprüfung präparierte Banknoten oder Papierzuschnitte. Die Testmedien können für die Überprüfung einer oder mehrerer Eigenschaften eines einzelnen Sensors der Wertdokumentbearbeitungsvor- richtung ausgebildet sein, dann handelt es sich um ein sogenanntes "lokales Testmedium", oder für die Überprüfung mehrerer oder aller relevanten Eigenschaften von mehreren oder allen relevanten Sensoren, dann handelt es sich um ein sogenanntes "globales Testmedium".The value documents are checked by means of several sensors, which differ depending on the value document property to be checked. The sensors are checked at regular intervals with regard to their correct functionality, adjustment and / or calibration. This check is usually carried out using special test media. "Test media" in the sense of the present invention are only those functional test, adjustment and / or calibration aids which are capable of being run and which are specially prepared, that is to say, for example, bank notes or paper blanks specially prepared for checking. The test media can be designed to check one or more properties of an individual sensor of the document processing device, in which case it is a so-called "local" one Test medium ", or for checking several or all relevant properties of several or all relevant sensors, then it is a so-called" global test medium ".
Im Falle von lokalen Testmedien ist zur vollständigen Überprüfung aller Sensoren der Wertdokumentbearbeitungsvorrichrung eine größere Anzahl unterschiedlicher Testmedien erforderlich, wohingegen im Falle eines globalen Testmediums anhand eines einzigen Testmediums alle Eigenschaften und Sensoren in der Wertdokumentbearbeitungsvorrichtung überprüft wer- den können, jedoch nur mit Eigenschaften, die die Testmedien tatsächlich aufweisen. Die erstgenannte Variante ist zwar flexibel, wegen der großen Anzahl von verschiedenen Testmedien aber entsprechend aufwändig und teuer. Demgegenüber ist die zweitgenannte Variante zwar preiswerter, jedoch wenig flexibel, da sie an mit unterschiedlichen Sensoren ausgestatteten Wertdokumentbearbeitungsvorrichtungen nicht eingesetzt werden können. Für Jede Wertdokumentbearbeirungsvorrichtung ist aber, mit einem gewissen Aufwand, ein Satz aus globalen und lokalen Testmedien zusammenstellbar, der alle notwendigen Test- und Justieraufgaben abdeckt.In the case of local test media, a larger number of different test media is required to completely check all sensors of the document processing device, whereas in the case of a global test medium, all properties and sensors in the document processing device can be checked using a single test medium, but only with properties that Actually have test media. The first-mentioned variant is flexible, but due to the large number of different test media, it is correspondingly complex and expensive. In contrast, the second-mentioned variant is cheaper, but not very flexible, since it cannot be used on value document processing devices equipped with different sensors. For each document processing device, however, a set of global and local test media can be put together with a certain effort, which covers all necessary test and adjustment tasks.
Aufgabe der vorliegenden Erfindung ist es daher, ein Verfahren zur Funktionsprüfung, Justierung und/ oder Kalibrierung von mindestens einem Sensor in einer Wertdokumentbearbeitungsvorrichtung, eine entsprechende Wertdokumentverarbeitungsvorrichtung und Testmedien zur Durchführung des Verfahrens zur Verfügung zu stellen, welche dem Stand der Technik hinsichtlich Flexibilität, bei möglichst geringem Aufwand, überlegen sind.It is therefore the object of the present invention to provide a method for functional testing, adjustment and / or calibration of at least one sensor in a value document processing device, a corresponding value document processing device and test media for carrying out the method, which are state of the art in terms of flexibility, if possible little effort, are superior.
Diese Aufgabe wird erfindungsgemäß durch ein Verfahren, eine Wertdoku- mentbearbeitungsvorrichtung, Testmedien und einem System bestehend aus der Wertdokumentbearbeirungsvorrichrung und den Testmedien mit den Merkmalen der unabhängigen Ansprüchen gelöst. In davon abhängigen Ansprüchen sind vorteilhafte Weiterbildungen und Ausgestaltungen der Erfindung angegeben.This object is achieved according to the invention by a method, a value document processing device, test media and a system consisting of the value document processing device and the test media with the Features of the independent claims solved. Advantageous developments and refinements of the invention are specified in claims dependent thereon.
Dementsprechend weisen die Testmedien, anhand welcher die Funktionsprüfung, Justierung und/ oder Kalibrierung der Wertdokumentbearbei- tungsvorrichtung durchgeführt wird, Kennungen auf, anhand welcher die Testmedien unterscheidbar sind. Die Kennungen können für alle Testmedien verschieden sein, können aber auch für Gruppen von Testmedien identisch sein. In einem Datenspeicher, der Bestandteil der Banknotenbearbeitungsvorrichtung sein kann, der aber auch ein elektronisches Speichermedium zur Verwendung in der Banknotenbearbeitungsvorrichtung sein kann, sind einzelnen Kennungen bestimmte Informationen darüber zugeordnet, welcher Sensor oder welche Sensoren der Banknotenbearbeitungsvorrichtung in Be- zug auf welche Eigenschaft oder Eigenschaften anhand des die jeweiligeAccordingly, the test media, on the basis of which the functional test, adjustment and / or calibration of the value document processing device is carried out, have identifications by means of which the test media can be distinguished. The identifiers can be different for all test media, but can also be identical for groups of test media. In a data memory, which can be a component of the banknote processing device, but which can also be an electronic storage medium for use in the banknote processing device, individual identifiers are assigned specific information about which sensor or sensors based on which property or properties of the banknote processing device of each
Kennung tragenden Testmediums zu prüfen, justieren und/ oder kalibrieren ist oder sind.To test, adjust and / or calibrate the test medium carrying the identifier.
Dies bietet den Vorteil, dass alle Testmedien abgesehen von ihrer Kennung äußerlich identisch und daher als globales Testmedium geeignet sind, d. h. insbesondere mehrere oder alle zu überprüfenden Eigenschaften aufweisen. Andererseits können dieselben Testmedien auch als lokale Testmedien verwendet werden. Ob ein Testmedium ein globales oder ein lokales Testmedium ist, hängt mit Ausnahme von den tatsächlich auf dem Testmedium vor- handenen Eigenschaften allein davon ab, welche Informationen der zugehörigen Kennung in dem von dem Testmedium unabhängigen Datenspeicher zugeordnet sind. Insbesondere braucht das jeweilige Testmedium selbst keinerlei spezifische Informationen darüber zu besitzen, welcher Sensor der Wertdokumentbearbeitungsvorrichtung auf welche Eigenschaft zu überprü- fen ist. Die Kennung selbst jedenfalls ist insoweit völlig unspezifisch und wird erst durch die Zuordnung der gespeicherten Informationen entsprechend spezifiziert.This offers the advantage that, apart from their identification, all test media are externally identical and are therefore suitable as a global test medium, ie in particular they have several or all properties to be checked. On the other hand, the same test media can also be used as local test media. With the exception of the properties actually present on the test medium, whether a test medium is a global or a local test medium depends solely on what information is associated with the associated identifier in the data memory independent of the test medium. In particular, the respective test medium itself does not need to have any specific information about which sensor of the value document processing device is to be checked for which property. fen is. In this respect, the identifier itself is completely unspecific and is only specified accordingly when the stored information is assigned.
Ein besonderer Vorteil besteht weiter auch darin, dass Testmedien mit unterschiedlicher Kennung durchaus dieselben Informationen zugeordnet werden können.Another particular advantage is that test media with different identifiers can be assigned the same information.
Dieser Vorteil sei an folgendem Beispiel erläutert: Für die Kalibrierung eines Sensors läßt man üblicherweise eine größere Anzahl von Testmedien durch die Wertdokumentbearbeitungsvorrichtung laufen, insbesondere wenn die Kalibrierung mit einem adaptivem Lernprozess verknüpft ist. Stellt sich erst im Kalibrierungsprozess heraus, dass die Testmedien mit der dafür vorgesehenen Testmedienkennung für die beabsichtigte Kalibrierung zahlenmäßig nicht ausreichen, können durch Umprogrammieren der gespeicherten Informationen kurzerhand weiteren Testmedien mit einer anderen Testmedi- umkennung aber der gleichen zu kalibrierenden Eigenschaft, die gleichen Informationen zugeordnet werden, die zur Kalibrierung des fraglichen Sensors erforderlich sind. Diese "umprogrammierten" Testmedien lässt man dann mit den eigentlichen für die Kalibrierung vorgesehenen Testmedien zur Kalibrierung des Sensors durch die Wertdokumentbearbeitungsvorrich- rung laufen.This advantage is explained using the following example: For the calibration of a sensor, a larger number of test media are usually run through the value document processing device, in particular if the calibration is linked to an adaptive learning process. If it only becomes apparent in the calibration process that the number of test media with the intended test medium identifier is not sufficient for the intended calibration, by reprogramming the stored information other test media with a different test medium identifier but with the same property to be calibrated can be assigned the same information required to calibrate the sensor in question. These "reprogrammed" test media are then run through the value document processing device with the actual test media provided for the calibration for the calibration of the sensor.
Den Kennungen sind im Datenspeicher außer den Informationen über die zu überprüfenden Sensoren und Eigenschaften weitere Informationen zugeordnet, wie beispielsweise die Grenzen, innerhalb welcher die Sensoreigenschaften zu liegen haben, um als funktionsfähig bzw. "FIT", d. h. "funktionsunfähig" bzw. "UNFIT" eingestuft zu werden. Je nach den gespeicherten Informationen kann der entsprechende Sensor auch einen Selbsttest durchführen oder das Ergebnis eines zuvor durchgeführten Selbsttests mitteilen, der zu einer Fehlermeldung führen kann, wenn z.B. die Sensoreigenschaft außerhalb vorgegebener Grenzen liegt. Oder der Sensor justiert oder kalibriert sich neu auf Basis des oder der durchlaufenden Testmedien.In addition to the information about the sensors and properties to be checked, the identifiers in the data memory are assigned further information, such as the limits within which the sensor properties have to lie in order to be functional or "FIT", ie "non-functional" or "UNFIT" to be classified. Depending on the information stored, the corresponding sensor can also carry out a self-test or report the result of a previously performed self-test, which can lead to an error message if, for example, the sensor property is outside of specified limits. Or the sensor adjusts or recalibrates itself on the basis of the test medium (s) running.
Insbesondere im Falle einer Neukalibrierung mittels einer Gruppe von Testmedien ist es beispielsweise auch denkbar, dass sich nur die Kennung des ersten und des letzten Testmediums von der Kennung der übrigen Testmedien unterscheidet, wobei der ersten Kennung eine Information bzw. eine Funktion zugeordnet wird, wonach die Eigenschaften des zu kalibrierenden Sensors auf einen Ausgangswert gesetzt werden, und der Kennung des letzten Testmediums die Information bzw. Funktion zugeordnet wird, dass der Kalibriervorgang abgeschlossen ist. Hierzu ist es erforderlich, dass die Wertdokumentbearbeitungsvorrichtung nach Erkennen des "Strat- Testmediums" den Lern- und/ oder Kalibrierprozess initiiert und bei Erkennen des "Stopp-Testmediums" beendet.In particular in the case of a recalibration using a group of test media, it is also conceivable, for example, that only the identifier of the first and the last test medium differ from the identifier of the other test media, the first identifier being assigned information or a function according to which the Properties of the sensor to be calibrated are set to an initial value, and the identifier or the last test medium is assigned the information or function that the calibration process has been completed. For this purpose, it is necessary for the document processing device to initiate the learning and / or calibration process after recognition of the "Strat test medium" and to end it when the "Stop test medium" is recognized.
Die Kennung kann eine Ziffernfolge, ein Barcode oder ein sonstiges leicht unterscheidbares, maschinenlesbares Muster sein. Die Herstellung der unter- schiedlichen Testmedien und auch ihre Identifizierung durch die Wertdo- kumentbearbeitungsvorrichtung ist somit wenig aufwendig und kann mit einfachen Mitteln erfolgen. Es ist auch möglich Wertdokumente wie Banknoten mit speziellen Eigenschaften zu versehen oder solche mit gefundenen speziellen Eigenschaften zu selektieren und diese als Testmedien zu ver- wenden, wobei z. B. bereits vorhandene Seriennummern der Banknoten als Kennung dienen kann. Zur besseren Unterscheidung von normalen Wertdokumenten sind zusätzliche machinenlesbare Modifikationen denkbar, z. B. Aufdrucken oder Aufstempeln eines Barcodes etc. Vorzugsweise ist die Kennung identisch auf beiden Seiten des Testmediums vorhanden, um eine seitenunabhängige und vorzugsweise auch lageunabhängige Erfassung der Kennung maschinell zu ermöglichen.The identifier can be a sequence of digits, a barcode or some other easily distinguishable, machine-readable pattern. The production of the different test media and also their identification by the value document processing device is thus not very complex and can be done with simple means. It is also possible to provide documents of value such as banknotes with special properties or to select documents with found special properties and to use them as test media. B. existing serial numbers of the banknotes can serve as an identifier. For better differentiation from normal documents of value, additional machine-readable modifications are conceivable, e.g. B. printing or stamping a barcode etc. The identifier is preferably present identically on both sides of the test medium in order to enable machine-independent detection of the identifier, which is preferably also position-independent.
Gemäß einer Weiterbildung der Erfindung werden die Sensoreigenschaften vor der ersten Inbetriebnahme der Wertdokumentbearbeitungsvorrichtung mittels der zuvor beschriebenen Testmedien geprüft, justiert und kalibriert. Die für diese ursprüngliche Messung verwendeten Testmedien werden nachfolgend als Master-Testmedien bezeichnet und bilden ein Master- Testmedienset, welches sorgfältig dokumentiert und aufbewahrt wird. Die mit dem Master-Testmedienset ermittelten Sensormessdaten werden nachfolgend als Master-Messdaten und der erstmalige Prüf-, Justier- und/ oder Kalibriervorgang der Wertdokumentbearbeitungsvorrichtung als Master- Testmedienlauf bezeichnet. Während ein Testmedienlauf mit normalen Testmedien einen rein qualitativen Charakter hat, nämlich beispielsweise der Prüfung auf Toleranzeinhaltung sowie Justierung und Kalibrierung dient, ohne dass der konkrete Messwert des jeweiligen Sensors von entscheidender Bedeutung ist, werden beim Master-Testmedienlauf zusätzlich die Master- Messdaten quantitativ ermittelt. Die Master-Messdaten werden in der Wert- dokumentbearbeitungsvorrichtung gespeichert, beispielsweise in demselben Datenspeicher wie die Testmedien-Kennungsinformationen. Die Master- Messdaten können auch Daten umfassen, die der jeweilige Sensor in einem Selbsttest gewonnen hat.According to a development of the invention, the sensor properties are checked, adjusted and calibrated using the test media described above before the value document processing device is started up for the first time. The test media used for this original measurement are referred to below as master test media and form a master test media set, which is carefully documented and kept. The sensor measurement data determined using the master test media set are referred to below as master measurement data and the first-time test, adjustment and / or calibration process of the value document processing device is referred to as the master test media run. While a test media run with normal test media has a purely qualitative character, namely, for example, it serves to check compliance with tolerances as well as adjustment and calibration, without the specific measured value of the respective sensor being of decisive importance, the master test data run is also determined quantitatively in the master test media run. The master measurement data are stored in the value document processing device, for example in the same data memory as the test medium identification information. The master measurement data can also include data that the respective sensor has obtained in a self-test.
Mittels der gespeicherten Master-Messdaten läßt sich jederzeit überprüfen, inwieweit sich die in einem Testmedienlauf konkret gemessenen Messwerte eines Sensors von den Master-Messdaten unterscheiden. Dies ermöglicht eine Trenderkennung und ein Austauschen des betreffenden Sensors bevor es zu einem Versagen des Sensors und damit zum Stillstand der Wertdoku- mentbearbeitungsvorrichtung kommt. Nur anhand der gespeicherten Master-Messdaten können Drifteffekte und Ausreißer der Sensorleistung erkannt werden. Eine exakte Überprüfung der Sensoreigenschaften und etwaiger Abweichungen vom Master-Meßwert lässt sich am besten mit dem Ma- ster-Testmedienset selbst durchführen. Deshalb wird das Master- Testmedienset, mit welchem die Wertdokumentbearbeitungsvorrichtung vor ihrer Auslieferung an einen Kunden werkseitig eingestellt wurde, mit an den Kunden ausgeliefert. Auf diese Weise bietet die vorliegende Erfindung dem Benutzer einer Wertdokumentbearbeitungsvorrichtung eine perfekte und flexible Möglichkeit zur Funktionsprüfung, Justierung und/ oder Kalibrierung einer Wertdokumentbearbeitungsdvorrichtung.Using the stored master measurement data, it can be checked at any time to what extent the measured values of a sensor specifically measured in a test media run differ from the master measurement data. This enables a trend detection and an exchange of the sensor in question before the sensor fails and thus the value documentation stops. ment processing device comes. Drift effects and outliers in sensor performance can only be identified using the stored master measurement data. An exact check of the sensor properties and any deviations from the master measured value can best be carried out with the master test media set itself. Therefore, the master test media set, with which the value document processing device was set at the factory before it was delivered to a customer, is also delivered to the customer. In this way, the present invention offers the user of a document processing device a perfect and flexible possibility for functional testing, adjustment and / or calibration of a document processing device.
Nachfolgend wird die Erfindung beispielhaft anhand der einzigen begleitenden Zeichnung erläutert.The invention is explained below by way of example with reference to the only accompanying drawing.
Die Figur zeigt schematisch einen wesentlichen Teil eines Verfahrens gemäß der vorliegenden Erfindung zur Funktionsprüfung, Justierung und/ oder Kalibrierung von Sensoren für Wertdokumente, insbesondere Banknoten. Ein Test-Medienset bestehend aus in diesem Beispiel lokalen Testmedien mit Kennungen TM-1 bis TM-6, wird einer nicht dargestellten Banknotenbearbeitungsvorrichtung als Stapel zugeführt. Die Testmedien TM-1 bis TM-6 sind gleichartig aufgebaut und unterscheiden sich lediglich in der Kennung. In einer Vereinzelervorrichtung werden die Testmedien sukzessive vereinzelt und laufen über eine Transportvorrichtung durch die Banknotenbearbei- tungsvorrichtung, wo sie von Sensoren Sl, S2 in Bezug auf bestimmte Echt- heits- und Qualitätsmerkmale geprüft werden. In der schematischen Darstellung gemäß der einzigen Figur sind die Testmedien mit Kennung TM-6 und TM-5 vereinzelt und in Pfeilrichtung innerhalb der Banknotenbearbeitungsvorrichtung transportiert worden. An einer ersten Position innerhalb der Banknotenbearbeitungsvorrichtung wird mittels eines Kennungssensors 1 die Kennung des jeweiligen Testmediums erfasst. Im dargestellten Beispielsfalle erfasst der Kennungssensor 1 momentan die Kennung TM-5. Die erfasste Kennung TM-5 wird an eine Datenverarbeitungseinrichtung 2 wei- tergeleitet, in der zu jeder möglichen Kennung spezielle Informationen gespeichert sind. In der Datenverarbeitungseinrichtung 2 werden somit der jeweils erfassten Kennung ein spezieller Satz von fest vorgegebenen Informationen zugeordnet. Die den Kennungen TM-1 bis TM-6 zugeordneten Informationen II bis 16 können über eine Eingabe 3 spezifiziert und prinzipiell jederzeit umprogrammiert werden.The figure schematically shows an essential part of a method according to the present invention for functional testing, adjustment and / or calibration of sensors for documents of value, in particular banknotes. A test media set consisting of local test media with identifiers TM-1 to TM-6 in this example is fed as a stack to a bank note processing device (not shown). The test media TM-1 to TM-6 are constructed in the same way and only differ in their identification. The test media are successively separated in a separating device and run through a transport device through the banknote processing device, where they are checked by sensors S1, S2 with regard to certain authenticity and quality features. In the schematic illustration according to the single figure, the test media with identifiers TM-6 and TM-5 have been separated and transported in the direction of the arrow within the bank note processing device. In a first position within the banknote processing device, the identifier of the respective test medium is detected by means of an identifier sensor 1. In the illustrated example, the identification sensor 1 currently detects the identification TM-5. The detected identifier TM-5 is forwarded to a data processing device 2, in which special information is stored for each possible identifier. In the data processing device 2, a special set of fixedly specified information is thus assigned to the identifier that is recorded in each case. The information II to 16 assigned to the identifiers TM-1 to TM-6 can be specified via an input 3 and, in principle, can be reprogrammed at any time.
Im dargestellten Beispielsfall werden der Kennung "TM-5" die Informationen 15 zugeordnet. Die Informationen 15 umfassen Angaben über den Sensor oder die Sensoren, die anhand des Testmediums mit der Kennung TM-5 zu prüfen, justieren oder kalibrieren sind, sowie zusätzliche konkrete Angaben zur Durchführung der Prüfung, Justierung oder Kalibrierung. Im dargestellten Beispielsfall ist das Testmedium mit Kennung TM-5 gemäß der Information 15 zur Prüfung des Sensors Sl bestimmt, und die Informationen 15 enthalten dazu beispielsweise die zusätzliche Angabe, dass der Sensor Sl, der beispielsweise ein mittels IR-Transmissionsstrahlung arbeitender Dickensensor ist, bezüglich seiner IR-Empfangseigenschaften überprüft werden soll, die in einem vorgegebenen Toleranzbereich liegen müssen, damit der Sensor Sl als "FIT" eingestuft wird. Diese Funktionsprüfung erfolgt natürlich erst, nachdem das Testmedium mit Kennung TM-5 an die Stelle vorgerückt ist, an der sich der Sensor Sl befindet. Dort befindet sich gegenwärtig noch dasIn the example shown, the identifier "TM-5" is assigned the information 15. The information 15 includes information about the sensor or sensors that are to be checked, adjusted or calibrated using the test medium with the identifier TM-5, as well as additional specific information for carrying out the test, adjustment or calibration. In the example shown, the test medium with the identifier TM-5 is determined in accordance with the information 15 for testing the sensor S1, and the information 15 contains, for example, the additional information that the sensor S1, which is, for example, a thickness sensor working by means of IR transmission radiation, with respect to its IR reception properties are to be checked, which must be within a predetermined tolerance range, so that the sensor S1 is classified as "FIT". Of course, this function test only takes place after the test medium with identifier TM-5 has advanced to the position at which the sensor S1 is located. That is currently still there
Testmedium mit Kennung TM-6, anhand dessen die Funktionsfähigkeit des Sensors S2 geprüft wird. Sobald das Testmedium mit Kennung TM-5 an die entsprechende Stelle vorgerückt ist, und der Dickensensor Sl zu diesem Testmedium einen IR- Transmissionswert gemessen hat, wird in der Datenverarbeitungseinheit 2 geprüft, ob der gemessene IR-Dickenmesswert innerhalb des durch die In- formationen 15 vorgegebenen Toleranzbereichs liegt. Ist dies der Fall, so wird der Sensor Sl und das Testmedium TM-5 als "FIT" eingestuft und das Testmedium TM-5 in einen "FIT- Ausgabeschacht" weitergeleitet. Liegt der Messwert außerhalb des vorgegebenen Toleranzbereichs, wird der Sensor Sl und das Testmedium TM-5 als "UNFIT" eingestuft und das Testmedium TM-5 in einen "UNFIT- Ausgabeschacht" weitergeleitet. Wenn eine Bearbeitung von Testmedien nicht möglich ist, beispielsweise im Falle eines Doppelabzugs, werden die Testmedien in einem "Reject-Ausgabefach" abgelegt. Die bedienende Person legt alle Testmedien aus dem Reject-Ausgabefach wieder in den Vereinzelner, bis alle Testmedien als "FIT" oder "UNFIT" ein- gestuft sind. Gleichzeitig erhält die bedienenden Person ohne weitere Hilfsmittel einen Überblick über den Zustand der Banknotenbearbeitungsvorrichtung bzw. deren Sensoren: liegen alle Testmedien in einem "FIT- Ausgabeschacht", so ist die Maschine uneingeschränkt arbeitsfähig, befinden sich Testmedien in einem "UNFIT-Ausgabeschacht", wird die Notwendigkeit ei- ner Wartung erkennbar.Test medium with identifier TM-6, on the basis of which the functionality of sensor S2 is checked. As soon as the test medium with identifier TM-5 has advanced to the corresponding position and the thickness sensor S1 has measured an IR transmission value for this test medium, the data processing unit 2 checks whether the measured IR thickness measurement value falls within the range indicated by the information 15 predetermined tolerance range. If this is the case, the sensor S1 and the test medium TM-5 are classified as "FIT" and the test medium TM-5 is forwarded to a "FIT output shaft". If the measured value lies outside the specified tolerance range, the sensor S1 and the test medium TM-5 are classified as "UNFIT" and the test medium TM-5 is forwarded to a "UNFIT output shaft". If it is not possible to process test media, for example in the event of a double deduction, the test media are stored in a "reject output bin". The operator puts all test media from the reject output tray back into the separator until all test media are classified as "FIT" or "UNFIT". At the same time, the operator gets an overview of the state of the banknote processing device or its sensors without any additional aids: if all test media are in a "FIT delivery slot", the machine is fully functional, if there are test media in a "UNFIT delivery slot" recognizable the need for maintenance.
Anhand des Testmediums mit Kennung TM-5 wurde somit eine Funktionsprüfung des Dickensensors Sl durchgeführt Das nächstfolgende Testmedium mit Kennung TM-4 kann beispielsweise zur Justierung eines ande- ren, hier nicht näher dargestellten Sensors dienen. Die darauf folgenden fünf Testmedien mit Kennungen TM-3, TM-2 und TM-1 dienen der Kalibrierung eines ebenfalls nicht näher dargestellten Sensors. Das Testmedium mit Kennung TM-3 bewirkt zunächst aufgrund der ihr zugeordneten Informationen 13, dass ein spezieller Sensor in einen Kalibriermodus versetzt wird, indem beispielsweise die Schwellenparameter der internen Bewertung eines zu kalibrierenden Parameters modifiziert werden. Anhand der drei nachfolgenden Testmedien mit Kennung TM-2 erfolgt dann eine Kalibrierung des betreffenden Sensors, und anhand des letzten Testmediums mit Kennung TM-1 wird der Sensor wieder auf Normalbetrieb zurückgestellt und gleichzeitig eine Überprüfung der Kalibrierung vorgenommen. Reicht die Anzahl der Testmedien mit Kennzeichnung TM-2 zur Kalibrierung nicht aus, so können weitere Testmedien mit anderen Kennungen oder sogar Banknoten zwischen die Testmedien mit Kennungen TM-3 und TM-1 gelegt werden und der Ka- libriervorgang noch einmal wiederholt werden. Das setzt voraus, dass die den Kennungen der hinzugefügten Testmedien bzw. Banknoten zugeordneten Informationen so umprogrammiert werden, dass sie mit den Informationen 12 der Kennung TM-2 übereinstimmen.A function test of the thickness sensor S1 was thus carried out on the basis of the test medium with identifier TM-5. The next test medium with identifier TM-4 can be used, for example, to adjust another sensor, not shown here. The following five test media with identifications TM-3, TM-2 and TM-1 serve to calibrate a sensor, which is also not shown in detail. On the basis of the information 13 assigned to it, the test medium with identifier TM-3 initially causes a special sensor to be put into a calibration mode by For example, the threshold parameters of the internal evaluation of a parameter to be calibrated are modified. The sensor in question is then calibrated using the following three test media with identifier TM-2, and the sensor is reset to normal operation using the last test medium with identifier TM-1 and the calibration is checked at the same time. If the number of test media labeled TM-2 is not sufficient for calibration, additional test media with other IDs or even banknotes can be placed between the test media with IDs TM-3 and TM-1 and the calibration process repeated again. This presupposes that the information associated with the identifiers of the added test media or bank notes is reprogrammed in such a way that they match the information 12 of the identifier TM-2.
Das Verfahren zur Funktionsprüfung, Justierung und/ oder Kalibrierung der Sensoren muss nicht notwendigerweise in einem separaten Test erfolgen. Stattdessen können einzelne Testmedien'oder auch ein Testmedienset im Normalbetrieb der Banknotenbearbeitungsvorrichtung zwischen Umlaufbanknoten gelegt werden, die in üblicher Weise sortiert werden. Aufgrund der Kennung werden die Testmedien von der Banknotenbearbeitungsvorrichtung als solche identifiziert und in diesem Falle allesamt in das Reject- Ausgabefach ausgegeben, da in das oder die FIT- und UNFIT- Ausgabefächer die im Normalbetrieb zu sortierenden Banknoten ausgegeben werden. Die bei der Prüfung der Testmedien ermittelten Informationen über den Zustand der jeweils geprüften, justierten und/ oder kalibrierten Sensoren werden für jedes Testmedium, also spezifiziert nach den jeweiligen Kennungen, aufgezeichnet, um es dem Bediener der Banknotenbearbeitungsvorrichtung zu ermöglichen, anhand dieser Aufzeichnungen nachzuvollziehen, welche Testmedien als FIT oder UNFIT oder als Reject einzustufen sind. Die Test- medien im Reject-Ausgabefach werden den im Normalbetrieb zu sortierenden Banknoten erneut hinzugefügt, bis auch diese als FIT oder UNFIT eingestuft werden. Dabei ist anhand der Aufzeichnungen die Testmedien auszusortieren, die als FIT oder UNFIT erkannt wurden. Alternativ können auch alle Testmedien erneut bearbeitet werden, wenn die Banknotenbearbeitungsvorrichtung anhand der Aufzeichnungen alle Testmedien, für die bereits ein gültiges Ergebnis (FIT oder UNFIT) vorliegt, bei der erneuten Bearbeitung ignoriert. Die Einstufung als FIT bzw. UNFIT nimmt der Bediener dann zum Anlass, entsprechende Servicearbeiten, wie z. B. den Austausch von Sensoren oder deren Einstellung zu veranlassen.The method for functional testing, adjustment and / or calibration of the sensors does not necessarily have to be carried out in a separate test. Instead, individual test media ' or a test media set can be placed between circulating banknotes during normal operation of the banknote processing device, which are sorted in the usual way. On the basis of the identifier, the test media are identified as such by the banknote processing device and in this case are all output into the reject output compartment, since the banknotes to be sorted during normal operation are output into the FIT and UNFIT output compartments. The information determined during the test of the test media about the state of the respectively tested, adjusted and / or calibrated sensors are recorded for each test medium, i.e. specified according to the respective identifiers, in order to enable the operator of the banknote processing device to use these records to understand which ones Test media are classified as FIT or UNFIT or as a reject. The test- Media in the reject output bin are added to the banknotes to be sorted in normal operation until they are also classified as FIT or UNFIT. The test media that have been recognized as FIT or UNFIT must be sorted out on the basis of the records. Alternatively, all test media can also be processed again if the banknote processing device uses the recordings to ignore all test media for which a valid result (FIT or UNFIT) already exists during the renewed processing. The operator then uses the classification as FIT or UNFIT as an opportunity to carry out corresponding service work, such as B. to arrange for the exchange of sensors or their setting.

Gemäß einer bevorzugten Weiterbildung der Erfindung ist vorgesehen, dass zusätzlich zu den Informationen II bis 16, die den Kennungen TM1 bis TM6 zugeordnet sind, weitere Informationen gespeichert sind, die den einzelnen Sensoren Sl, S2, ... zugeordnet sind. Bei diesen weiteren Informationen handelt es sich um konkrete Messdaten, die bei der erstmaligen Inbetriebnahme der Banknotenbearbeitungsvorrichtung für die jeweiligen Sensoren ermittelt wurden. Diese als Master-Messdaten bezeichneten Sensordaten werden mit den bei den Testmediendurchläufen konkret ermittelten Sensormessdaten verglichen, so dass eine qualitative Aussage über die Sensoreigenschaften möglich ist. Vorzugsweise werden zusätzlich die bei jedem Testmedien- durchlauf konkret ermittelten Sensoreigenschaften aufgezeichnet, so dass ein Trend erkennbar wird und ein Sensor ausgetauscht werden kann, bevor er aus dem vorgegebenen Toleranzbereich herausfällt. According to a preferred development of the invention, it is provided that in addition to the information II to 16 which are assigned to the identifiers TM1 to TM6, further information which is assigned to the individual sensors S1, S2,... Is stored. This additional information is specific measurement data that is used when starting up for the first time of the banknote processing device for the respective sensors were determined. These sensor data, which are referred to as master measurement data, are compared with the sensor measurement data specifically determined during the test media runs, so that a qualitative statement about the sensor properties is possible. In addition, the sensor properties specifically determined during each test medium run are preferably recorded, so that a trend can be recognized and a sensor can be replaced before it falls outside the specified tolerance range.
