Abstract

The invention relates to a transponder (1) comprising a data memory (4), in which important data concerning any object can be saved. An energy accumulator (5) is activated using an electric field, to obtain the desired data exchange. If necessary, the comparatively short range for the transmission of information of a passive system of this type can be significantly increased by an external electric energy supply (7). To achieve this, the transponder (1) has a coupling (6) for the contactless transmission of energy from a housing (9) of the energy supply (7), said housing being attached to a fixing element (10) for this purpose. Data can be registered at a limited range even after removal of the energy supply (7), without the risk of loss of data after long periods of time.

Description

Transponder transponder
Die Erfindung betrifft einen Transponder mit einem Datenspeicher, welcher zur Informationsübertragung mit elektrischer Energie versorgt werden muß.The invention relates to a transponder with a data memory, which must be supplied with electrical energy for the transmission of information.
Ein Transponder der genannten Art kann überall dort eingesetzt werden, wo insbesondere bewegliche Objekte identifiziert oder markiert werden sollen. Gegenüber dieser Art von unveränderlichen Informationsträgern, wie beispielsweise Barcode-Etiketten, haben Transponder den Vorteil, daß der Inhalt des Datenspeichers ohne unmittelbaren Kontakt zu der entsprechenden Antenne erfaßt werden kann. Der Transponder benötigt insbesondere keine Sichtverbindung zur Antenne und kann so auch durch Feststoffe hindurch gelesen werden. Eine exakte relative Positionierung bezüglich der Antenne ist ebenfalls nicht erforderlich.A transponder of the type mentioned can be used wherever, in particular, moving objects are to be identified or marked. Compared to this type of unchangeable information carrier, such as barcode labels, transponders have the advantage that the content of the data memory can be detected without direct contact with the corresponding antenna. In particular, the transponder does not require a line of sight to the antenna and can therefore be read through solids. An exact relative positioning with respect to the antenna is also not necessary.
Zur Informationsübertragung wird der Transponder zuerst mit Energie versorgt. Dies kann entweder direkt über Kontakte oder über ein elektromagnetisches Feld erfolgen. Nachdem ausreichend Energie für den Betrieb des Transponders vorhanden ist, wird die Datenüber- tragung initiiert. Danach kann die Datenübertragung zwischen dem Transponder und einer Sende-/Empfangseinheit erfolgen. Verschiedene Ausführungen des Transponders nutzen die Kontakte für die Energie- und Kommunikationsversorgung. Andere erlauben die Energieversorgung und Datentransfer über eine integrierte Antenne. Die Informationsübertragung kann dabei zyklisch wiederholt werden, solange sich der Transponder innerhalb der Reich- weite der Antenne im Übertragungsbereich befindet. Diese Reichweite ist insbesondere abhängig von der Antennengröße des Transponders und liegt in der Praxis zwischen 2 und 70 cm, teilweise darüber.To transmit information, the transponder is first supplied with energy. This can be done either directly via contacts or via an electromagnetic field. After sufficient energy is available to operate the transponder, the data transfer is initiated. The data can then be transmitted between the transponder and a transmitting / receiving unit. Different versions of the transponder use the contacts for the energy and communication supply. Others allow energy supply and data transfer via an integrated antenna. The information transmission can be repeated cyclically as long as the transponder is within the range of the antenna in the transmission area. This range is particularly dependent on the antenna size of the transponder and in practice is between 2 and 70 cm, sometimes more.
Da der Transponder in einer Vielzahl von Gehäuseformen zur Verfügung steht, kann er ent- sprechend flexibel in der Produktionsüberwachung und Steuerung eingesetzt werden. So kann an entsprechenden Kontrollpunkten jederzeit überprüft werden, in welchem Fertigungsabschnitt sich das Produkt befindet. Außerdem können beispielsweise Korrekturanweisungen oder Änderungswünsche auf den Datenspeicher des Transponders übertragen werden, um so einerseits eine flexible Fertigung zu erreichen, andererseits aber auch die Fertigungsqualität des Produktes zu erhöhen. Der so bei der Fertigungssteuerung und Materialüberwachung einsetzbare Transponder ermöglicht dabei einen Informationsaustausch während der Transportbewegung, wodurch vollautomatische Fertigungsprozesse und Überwachungen der laufenden Fertigung ohne einen Eingriff in den Produktionsablauf ermöglicht werden. Als nachteilig hat sich bei Arealen und Fertigungslinien erwiesen, daß die Reichweite unter Umständen bei sehr großen Objekten oder einer unbekannten Position des Objektes nicht ausreicht, um einen fehlerfreien Informationsaustausch sicherzustellen. Daher wird insbe- sondere bei einer unbekannten Position oder Orientierung des Objektes die Anordnung mehrerer Transponder oder Antennen erforderlich, wodurch ein zusätzlicher Aufwand entsteht.Since the transponder is available in a variety of housing shapes, it can be used flexibly in production monitoring and control. In this way, it can be checked at appropriate checkpoints at any time in which production section the product is located. In addition, correction instructions or change requests, for example, can be transferred to the data memory of the transponder in order to achieve flexible production on the one hand, but also to increase the production quality of the product on the other. The transponder, which can be used in production control and material monitoring, enables information to be exchanged during the transport movement, which enables fully automatic production processes and monitoring of ongoing production without interfering with the production process. It has proven disadvantageous for areas and production lines that the range may not be sufficient for very large objects or an unknown position of the object to ensure an error-free exchange of information. For this reason, in particular if an unknown position or orientation of the object is required, it is necessary to arrange a number of transponders or antennas, which results in additional effort.
Grundsätzlich läßt sich das Problem der unzureichenden Reichweite für die Informationsübertragung dadurch umgehen, daß ein als "aktives System" bekannter Transponder mit einem Energiespeicher eingesetzt wird, der eine eigene Energiequelle, insbesondere eine Batterie, mit sich führt. Hierdurch wird die Reichweite zur Informationsübertragung bis auf 100 m erhöht. Als nachteilig hierbei erweist sich jedoch, daß die Kommunikation mit dem Datenspeicher von dem Betriebszustand der Batterie abhängig ist und daher bei vollkommen entleerter Batterie keine Datenübertragung möglich ist. Sofern die vorhandenen Daten über einen langen Zeitraum benötigt werden, ist daher eine Erneuerung der Batterie erforderlich, was nach der Auslieferung des Objektes gewöhnlich mit erheblichen Problemen verbunden ist.Basically, the problem of insufficient range for information transmission can be avoided by using a transponder known as an "active system" with an energy store which carries its own energy source, in particular a battery. This increases the range for information transmission up to 100 m. It proves to be disadvantageous here that the communication with the data memory is dependent on the operating state of the battery and therefore no data transmission is possible when the battery is completely empty. If the existing data is required over a long period of time, the battery must be replaced, which is usually associated with considerable problems after delivery of the object.
Der Erfindung liegt daher die Aufgabe zugrunde, einen Transponder mit einem Datenspei- eher zu schaffen, bei dem ein Informationsaustausch auch über eine vergleichsweise große Distanz möglich ist. Dabei soll insbesondere ein unerwünschter Datenverlust über einen vergleichsweise langen Zeitraum ausgeschlossen sein.The invention is therefore based on the object of creating a transponder with a data memory, in which an information exchange is also possible over a comparatively large distance. In particular, undesired data loss over a comparatively long period of time should be excluded.
Diese Aufgabe wird erfindungsgemäß mit einem Transponder gemäß den Merkmalen des Patentanspruchs 1 gelöst. Die weitere Ausgestaltung der Erfindung ist den Unteransprüchen zu entnehmen.This object is achieved with a transponder according to the features of claim 1. The further embodiment of the invention can be found in the subclaims.
Erfindungsgemäß ist also ein Transponder vorgesehen, bei dem der Transponder zusätzlich mit einer Kupplung für eine elektrische Energieversorgung zur Vergrößerung der Reichweite des Transponders ausgestattet ist. Durch diese Kupplung kann der Transponder von seinem grundsätzlichen Aufbau als passives System, bei dem der Datenspeicher über einen langen Zeitraum durch die Einwirkung eines elektrischen Feldes aktiviert werden kann, mittels der Kupplung an eine externe elektrische Energieversorgung; zumindest vorübergehend in ein aktives System überführt werden. Mit diesem aktiven System wird eine wesentlich erhöhte Reichweite des Transponders erreicht, so daß auch bei Unkenntnis der genauen Position des Transponders, wie dies in der Praxis bei großen Objekten, beispielsweise bei Luftfahr- zeugen oder Schiffen, häufig vorkommt, in jedem Fall ein zuverlässiger Informationsaustausch sichergestellt ist. So kann der durch die Kupplung zum aktiven System erweiterte Transponder beispielsweise während des Herstellungsprozesses mit der hierfür notwendigen Energieversorgung verbunden werden und die Reichweite so bis auf 100 m erhöht werden. Nach Abschluß des Herstellungsprozesses ist eine derart erhöhte Reichweite nicht mehr erforderlich, so daß die Energieversorgung von dem Transponder getrennt werden kann. Die in dem Datenspeicher verbleibenden Daten können später durch die Einwirkung eines elektrischen Feldes mit einem vergleichsweise geringen Abstand aktiviert werden, und können so auch nach vielen Jahren noch zuverlässig erfaßt werden. Daher bietet sich der erfin- dungsgemäße Transponder insbesondere im Hinblick auf die zunehmenden Forderungen nach einer Wiederverwertung von Fahrzeugbauteilen an, wobei der Datenspeicher Aufschluß über die Art und die Beschaffenheit des Werkstoffes gibt, sowie Anleitungen zur Demontage enthält.According to the invention, a transponder is therefore provided in which the transponder is additionally equipped with a coupling for an electrical energy supply to increase the range of the transponder. This coupling allows the transponder to be designed as a passive system, in which the data memory can be activated over a long period of time by the action of an electrical field, by means of the coupling to an external electrical power supply; at least temporarily transferred to an active system. With this active system, a significantly increased range of the transponder is achieved, so that even if the exact position of the transponder is not known, as is the case in practice with large objects, for example in aviation witnesses or ships, often occurs, in any case a reliable exchange of information is ensured. For example, the transponder expanded by the coupling to the active system can be connected to the energy supply required for this during the manufacturing process and the range can be increased to 100 m. After completion of the manufacturing process, such an increased range is no longer necessary, so that the energy supply can be separated from the transponder. The data remaining in the data memory can later be activated by the action of an electrical field at a comparatively short distance, and can thus still be reliably recorded even after many years. The transponder according to the invention is therefore particularly suitable with regard to the increasing demands for recycling vehicle components, the data memory providing information about the type and nature of the material and instructions for dismantling.
Die Energieversorgung könnte während des Produktionsprozesses beispielsweise durch eine elektrische Kontaktierung mit einem Fördermittel, welches hierzu mit einer elektrischen Energiequelle ausgestattet ist, verbunden sein. Eine besonders vorteilhafte Ausgestaltung der vorliegenden Erfindung wird jedoch dann erreicht, wenn die Energieversorgung eine mitführbare Batterie aufweist. Hierdurch ist der Transponder sowohl während des Herstel- lungsprozesses als auch bei einer späteren Verwendung ohne die Energieversorgung frei beweglich. Der Transponder kann somit als eine autonome Baueinheit ausgestaltet werden, die dadurch gegenüber äußeren Einflüssen weitgehend unempfindlich ist.The energy supply could be connected during the production process, for example, by making electrical contact with a conveying device that is equipped with an electrical energy source for this purpose. A particularly advantageous embodiment of the present invention is achieved, however, if the energy supply has a portable battery. This allows the transponder to move freely during the manufacturing process as well as during later use without the power supply. The transponder can thus be designed as an autonomous structural unit, which is largely insensitive to external influences.
Eine andere besonders zweckmäßige Weiterbildung der vorliegenden Erfindung wird auch dadurch geschaffen, daß die Batterie wiederaufladbar ist. Hierdurch kann die Energieversorgung während des Herstellungsprozesses des mit dem Transponder ausgestatteten Objektes durch die Batterie erfolgen, die nach dem Aufladen mit einem anderen Transponder verbunden und daher für einen weiteren Zyklus einsetzbar ist. Es ist daher nicht erforderlich, für jeden Transponder eine neue Energieversorgung vorzusehen, so daß der Aufwand weiter reduziert werden kann.Another particularly useful development of the present invention is also created in that the battery is rechargeable. As a result, the energy supply during the manufacturing process of the object equipped with the transponder can be provided by the battery, which is connected to another transponder after charging and can therefore be used for a further cycle. It is therefore not necessary to provide a new energy supply for each transponder, so that the effort can be reduced further.
Hierbei ist auch besonders vorteilhaft, wenn die Kupplung zur berührungslosen Energieübertragung von der Energieversorgung auf den Transponder ausgeführt ist. Hierdurch werden Verschleißerscheinungen an der Kupplung weitgehend ausgeschlossen, so daß insbe- sondere eine Korrosion von Kontaktelementen vermieden wird. Dadurch können Fehlfunktionen verringert und der Transponder zugleich auch in einer aggressiven Umgebung einge- setzt werden. Die Kupplung ermöglicht dabei den universellen Einsatz der Energieversorgung bei allen bekannten Transponderbauarten. Dabei ist die Energieversorgung von dem Transponder elektrisch und galvanisch getrennt, so daß die Kupplung lediglich eine mechanische Verbindung darstellt.It is also particularly advantageous here if the coupling is designed for contactless energy transmission from the energy supply to the transponder. As a result, signs of wear on the coupling are largely excluded, so that in particular corrosion of contact elements is avoided. Malfunctions can thereby be reduced and the transponder can also be used in an aggressive environment. be set. The coupling enables universal use of the energy supply in all known transponder types. The power supply is electrically and galvanically isolated from the transponder, so that the coupling is only a mechanical connection.
Dabei ist es besonders günstig, wenn die Energieversorgung mit geringem Abstand zu der Kupplung an dem Transponder fixierbar ist. Mögliche Verluste bei der Energieübertragung können dadurch auf ein Minimum reduziert werden, so daß die Kapazität der Energieversorgung mit einem hohen Wirkungsgrad für die Informationsübertragung nutzbar ist.It is particularly advantageous if the energy supply can be fixed to the transponder at a short distance from the coupling. Possible losses in energy transmission can thereby be reduced to a minimum, so that the capacity of the energy supply can be used with a high degree of efficiency for information transmission.
Die Kupplung könnte lediglich für die elektrische Energieversorgung ausgeführt sein, so daß die Energieversorgung beispielsweise an einem Transportsystem angebracht wird. Besonders praxisnah ist hingegen auch eine Ausgestaltung der vorliegenden Erfindung, bei welcher die Kupplung zusätzlich zu der elektrischen Energieversorgung mit einer lösbaren Fixie- rung für ein die Energieversorgung aufnehmendes Gehäuse ausgestattet ist. Hierdurch kann durch die Kupplung sowohl die Energieversorgung des Transponders als auch deren mechanische Befestigung erfolgen. Hierzu kann das Gehäuse beispielsweise mit einem Gewinde oder einem Bajonettverschluß ausgestattet sein, um so eine problemlose und schnelle Fixierung zu erreichen, die insbesondere ohne ein spezielles Werkzeug sowohl manuell als auch automatisch durchführbar ist.The coupling could only be designed for the electrical energy supply, so that the energy supply is attached to a transport system, for example. On the other hand, an embodiment of the present invention is particularly practical, in which the coupling, in addition to the electrical energy supply, is equipped with a releasable fixation for a housing receiving the energy supply. As a result, both the power supply of the transponder and its mechanical attachment can take place through the coupling. For this purpose, the housing can be equipped, for example, with a thread or a bayonet lock in order to achieve a problem-free and quick fixation which can be carried out both manually and automatically, in particular without a special tool.
Eine andere vorteilhafte Weiterbildung wird dadurch geschaffen, daß die Kupplung zur formschlüssigen Fixierung der Energieversorgung ausgeführt ist. Hierdurch entsteht durch die Fixierung der Energieversorgung zugleich eine in sich geschlossene Einheit, die einerseits mühelos handhabbar ist, andererseits eine erhöhte Formstabilität aufweist und so gegenüber äußeren Krafteinwirkungen eine hohe Widerstandskraft aufweist. Die Fixierung kann dabei insbesondere auch durch eine Dichtung wasserdicht ausgeführt werden, um so einen Einsatz im flüssigen Medium zu gewährleisten.Another advantageous development is created in that the coupling is designed for the positive fixing of the energy supply. This fixes the energy supply at the same time creates a self-contained unit that is easy to handle on the one hand, and on the other hand has increased dimensional stability and thus has a high resistance to external forces. The fixation can in particular also be carried out watertight by a seal in order to ensure use in the liquid medium.
Besonders praktisch ist eine weitere Abwandlung der vorliegenden Erfindung dadurch, daß die Kupplung eine Clip-Verbindung zur Fixierung der Energieversorgung aufweist. Hierdurch kann die Energieversorgung mit wenigen Handgriffen fixiert oder getrennt werden, so daß ein flexibler Einsatz des Transponders erreicht wird. So kann beispielsweise auch in einem späteren Servicefall des Objektes der Transponder durch die Energieversorgung aktiviert werden, um so beispielsweise eine Fehlersuche zu vereinfachen. Eine andere besonders vorteilhafte Ausgestaltung wird auch dadurch geschaffen, daß die Kupplung zur Anordnung einer mit einer Sende-Empfangseinheit ausgestatteten Energieversorgung ausgeführt ist. Hierdurch kann durch die Anordnung der Energieversorgung zugleich die zur Informationsübertragung erforderliche Antenne bzw. der Empfänger verändert wer- den, so daß eine günstigere Form der Informationsübertragung erreicht werden kann. Zugleich entfällt dadurch der Aufwand, der zur Ausstattung des Transponders mit unterschiedlichen Sende-Empfangseinheiten erforderlich ist.Another modification of the present invention is particularly practical in that the coupling has a clip connection for fixing the energy supply. As a result, the energy supply can be fixed or separated in a few simple steps, so that flexible use of the transponder is achieved. Thus, for example, the transponder can also be activated by the energy supply in a later service case of the object, in order to simplify troubleshooting, for example. Another particularly advantageous embodiment is also created in that the coupling is designed to arrange an energy supply equipped with a transceiver unit. As a result, the arrangement of the energy supply can at the same time change the antenna or receiver required for the information transmission, so that a more favorable form of information transmission can be achieved. At the same time, this eliminates the effort required to equip the transponder with different transceiver units.
Eine weitere besonders praxisnahe Abwandlung der vorliegenden Erfindung wird dadurch erreicht, daß der Transponder zusätzlich mit einer Aufnahme für einen GPS-Empfänger ausgestattet ist. Hierdurch werden die Koordinaten des mit dem Transponder ausgestatteten Gegenstandes erfaßt und gegebenenfalls gespeichert. Bei einer nachfolgenden Auswertung der Daten kann somit auch der Standort des Transponders bestimmt werden, wodurch sich die Logistik und der Materialfluß vereinfachen läßt, wobei beispielsweise auch der Material- fluß des mit dem Transponder gekennzeichneten Gegenstandes nachvollzogen werden kann. Zudem erweist sich der Transponder dadurch zugleich als wirkungsvoller Schutz vor Diebstahl.Another particularly practical modification of the present invention is achieved in that the transponder is additionally equipped with a receptacle for a GPS receiver. As a result, the coordinates of the object equipped with the transponder are detected and, if necessary, stored. In a subsequent evaluation of the data, the location of the transponder can thus also be determined, as a result of which the logistics and the material flow can be simplified, wherein, for example, the material flow of the object identified with the transponder can also be traced. In addition, the transponder also proves to be effective protection against theft.
Die Erfindung läßt verschiedene Ausführungsformen zu. Zur weiteren Verdeutlichung ihres Grundprinzips ist eine davon in der Zeichnung dargestellt und wird nachfolgend beschrieben. Diese zeigt in einer Prinzipskizze einen erfindungsgemäßen Transponder 1. Dieser ist mit einem Gehäuse 2 ausgestattet, welches mit einer Ausformung 3 zur Fixierung an einem nicht weiter dargestellten Objekt ausgestattet ist. Im Inneren des Gehäuses 2 weist der Transponder 1 einen Datenspeicher 4 auf, welcher an einem Bauteilträger 5 angeordnet ist. Die Übertragung oder wahlweise Änderung von Daten erfolgt unter dem Einfluß eines elektrischen Feldes. Um den hierbei erforderlichen geringen Abstand für einen einwandfreien Informationsaustausch bei Bedarf auf einen für den praktischen Einsatz günstigeren Abstand zu vergrößern, ist der Transponder 1 weiterhin mit einer Kupplung 6 für eine externe Energieversorgung 7 ausgestattet. Hierdurch wird die Übertragungsleistung wesentlich erhöht, so daß der Informationsaustausch erheblich vereinfacht wird. Zum Schutz gegen Umwelteinflüsse ist die Kupplung 6 in einen Abschnitt 8 des Gehäuses 2 zurückgesetzt eingelassen, so daß die Energieübertragung berührungslos erfolgt. Hierbei erfolgt die Übertragung von einer Antenne 13 der Energieversorgung 7 auf eine weitere Antenne 14 des Transponders 1, die durch die Kupplung elektrisch und galvanisch voneinander getrennt angeordnet sind. Die Energieversorgung 7 ist mit einem Gehäuse 9 ausgestattet, welches mittels einer lösbaren Fixierung 10 an dem Transponder 1 befestigt wird und dadurch die Kupplung 6 zum Schutz gegen äußere Einflüsse dichtend einschließt. Diese beispielsweise als eine Clip-Verbindung ausgeführte formschlüssige Fixierung 10 kann nach Abschluß des Herstellungsprozesses mühelos von dem Transponder 1 getrennt werden, um so für weitere Einsätze bei anderen Transpondem nutzbar zu sein. Hierzu kann eine Batterie 11 der Energieversorgung 7 insbe- sondere auch wiederaufladbar sein. In dem Gehäuse 9 ist weiterhin auch eine zusätzliche Sende-Empfangseinheit 12 untergebracht, mit deren Hilfe die Übertragungsleistung beim Informationsaustausch weiter verbessert werden kann. Auch nach dem Entfernen der Energieversorgung 7 können die in dem Datenspeicher 4 enthaltenen Daten unter dem Einfluß des elektrischen Feldes uneingeschränkt erfaßt werden, wobei lediglich die verringerte Reichweite zu berücksichtigen ist. Daher ist es möglich, wesentliche Daten des Objektes, die hierbei auch Daten bezüglich einer gegebenenfalls erforderlichen Reparatur oder Demontage einschließen, auch nach einem langen Zeitraum zu erfassen. Der Transponder 1 ist weiterhin mit einem GPS-Empfänger 15 ausgestattet, um so auch Koordinaten des jeweiligen Standortes zu erfassen bzw. zu speichern und diese gegebenenfalls übertragen zu können. The invention allows various embodiments. To further clarify its basic principle, one of these is shown in the drawing and is described below. This shows a schematic diagram of a transponder 1 according to the invention. This is equipped with a housing 2, which is equipped with a shape 3 for fixing to an object, not shown. In the interior of the housing 2, the transponder 1 has a data memory 4 which is arranged on a component carrier 5. The transmission or optional change of data takes place under the influence of an electrical field. In order to enlarge the necessary small distance for a perfect information exchange to a more convenient distance for practical use, the transponder 1 is further equipped with a coupling 6 for an external energy supply 7. This significantly increases the transmission power, so that the exchange of information is considerably simplified. To protect against environmental influences, the coupling 6 is recessed into a section 8 of the housing 2, so that the energy transfer takes place without contact. Here, the transmission from an antenna 13 of the energy supply 7 to a further antenna 14 of the transponder 1 takes place, which are arranged electrically and galvanically separated from one another by the coupling. The power supply 7 is equipped with a housing 9 which is fastened to the transponder 1 by means of a releasable fixation 10 and thereby the coupling 6 for protection sealing against external influences. This form-fitting fixation 10, for example in the form of a clip connection, can be effortlessly separated from the transponder 1 after completion of the manufacturing process, so that it can be used for further uses with other transponders. For this purpose, a battery 11 of the energy supply 7 can in particular also be rechargeable. An additional transceiver unit 12 is also accommodated in the housing 9, with the aid of which the transmission performance when exchanging information can be further improved. Even after the power supply 7 has been removed, the data contained in the data memory 4 can be recorded without restriction under the influence of the electrical field, only the reduced range being taken into account. It is therefore possible to record essential data of the object, which in this case also includes data relating to any repair or dismantling that may be required, even after a long period of time. The transponder 1 is also equipped with a GPS receiver 15 in order to also record or save coordinates of the respective location and to be able to transmit these if necessary.
