Abstract
Description
Die vorliegende Erfindung betrifft einen Transponder nach dem Oberbegriff des Patentanspruches 1.The present invention relates to a transponder the preamble of claim 1.
Ein solcher Transponder mit dazugehörigem Lesegerät ist z. B. in in dem Prospekt "Elektronische Identifikation Sy stem Trovan" der Firma AEG Aktiengesellschaft, Ulm vom Juni 1992 beschrieben. Der dort beschriebene Transponder besitzt einen Festkodespeicher als Nutzspeicher.Such a transponder with associated reader is e.g. B. in the prospectus "Electronic Identification Sy stem Trovan "from AEG Aktiengesellschaft, Ulm from June 1992. The transponder described there has a fixed code memory as useful memory.
Für viele Anwendungszwecke, z. B. für die Anwendung des Transponders als zeitlich begrenzte Fahrkarte (Monats karte) oder als Eintrittskarte (Skipaß) wäre es wünschens wert zusätzlich zu den bisherigen Verwendungs möglichkeiten den Nutzspeicher der Transponder wenigstens teilweise verändern zu können. Dabei soll die Veränderung nur Berechtigten möglich sein. Beispielsweise wäre es er wünscht, daß von einem Berechtigten eine Fahrkarte für den Monat Mai abgeändert werden kann als Fahrkarte für den Mo nat Juni. Das Auslesen des Nutzspeichers soll nach wie vor von einem einfachen Lesegerät möglich sein, das z. B. am Eingang eines Busses installiert ist und den diesen Trans ponder als Fahrkarte tragenden Benutzer auf die berech tigte Benutzung überprüft.For many applications, e.g. B. for the application of Transponders as a temporary ticket (monthly card) or as an admission ticket (ski pass) it would be desirable worth in addition to the previous use Possibilities the useful memory of the transponders at least to be able to change partially. The change is meant to be only authorized persons are possible. For example, it would be him wishes a person entitled to a ticket for the The month of May can be changed as a ticket for Mon. nat June. The readout of the useful memory should still be be possible by a simple reader that z. B. on Input of a bus is installed and this trans ponder as a ticket-carrying user to the calc checked usage.
Von wesentlicher Bedeutung ist dabei, daß das Auslesen des Nutzungsspeichers berührungslos über relativ größere Ent fernung erfolgen kann, so daß z. B. ein einsteigender Fahr gast die Fahrkarte, also den Transponder, nicht unbedingt in eine spezielle Lage bringen muß und schon garnicht in ein Gerät einführen muß. Die Abfertigung wird dadurch ver einfacht und beschleunigt, insbesondere dann, wenn der Fahrgast die Fahrkarte noch nicht einmal aus der Tasche nehmen muß.It is essential that the reading of the Usage memory contactlessly over relatively larger Ent distance can be done so that z. B. a boarding ride not necessarily the ticket, i.e. the transponder in a special position and certainly not in must introduce a device. The clearance is thereby ver simplifies and accelerates, especially if the Passenger does not even have the ticket out of his pocket must take.
Die Aufgabe der Erfindung wird darin gesehen einen Trans ponder eingangs genannter Art so zu verbessern, daß eine Veränderung des Speicherinhalts des Nutzspeichers durch einen Berechtigten möglich ist, wobei nur der Berechtigte in der Lage ist, eine in Transponder integrierte Ände rungssperre auszuschalten.The object of the invention is seen in a trans to improve ponder of the type mentioned so that a Change in the memory content of the useful memory by an authorized person is possible, whereby only the authorized person is able to change a transponder switch off.
Diese Aufgabe wird durch die Merkmale des Kennzeichens des Patentanspruches 1 gelöst. Fortschrittliche Weiterbildun gen der Erfindung finden sich in Unteransprüchen.This task is characterized by the characteristics of the license plate Claim 1 solved. Advanced training gene of the invention can be found in the dependent claims.
Anhand des in der Figur schematisch dargestellten Ausfüh rungsbeispieles wird die Erfindung nachfolgend näher er läutert.Based on the embodiment shown schematically in the figure Rungsbeispieles the invention he below purifies.
Die Figur zeigt im Prinzip die elektronische Teile eines Transponders, die üblicherweise mit Ausnahme der Antennen anordnung auf einem Halbleiterchip integriert sind. Ein solcher Transponder kann ein flaches Bauteil sein, das auf einer Karte oder dergleichen angeordnet ist oder er kann eine inplantierbare Kapsel sein. Zum Betrieb wird er ver anlaßt durch ein in die Antennenanordnung induktiv einge koppeltes elektromagnetisches Feld, das nicht nur die Be triebssignale sondern auch die Gleichenergie zur Gleich stromversorgung des Transponders liefert.The figure shows in principle the electronic parts of a Transponders, usually with the exception of the antennas arrangement are integrated on a semiconductor chip. A such transponder can be a flat component that is based on a card or the like is arranged or he can an implantable capsule. It is used for operation causes inducted into the antenna arrangement coupled electromagnetic field that not only the loading drive signals but also the same energy to the same supplies power to the transponder.
Mit 1 ist die Antennenanordnung bezeichnet die zum einen das elektromagnetische Feld aufnimmt und zum anderen die abgefragte Information abstrahlt. In elektromagnetischer Korrespondenz mit dem Transponder steht ein Lese-und/oder Schreibgerät, das die elektromagnetischen Wellen zum Be trieb des Transponders aus sendet und die von diesem abgestrahlten elektromagnetischen Wellen aufnimmt. 1 designates the antenna arrangement which on the one hand receives the electromagnetic field and on the other hand emits the requested information. In electromagnetic correspondence with the transponder there is a reading and / or writing device which transmits the electromagnetic waves for operating the transponder and receives the electromagnetic waves emitted by the transponder.
Der Transponder enthält weiterhin ein von der aufgenomme nen HF-Energie betriebenes Stromversorgungsteil 2, einen Frequenzteiler 3, einen Modulator 4, einen Nutzspeicher 5 dessen Speicherinhalt veränderbar ist und einen Datensen der 7. Der Frequenzteiler 3 erzeugt die Transponder-Sen derfrequenz die zweckmäßig die halbe Empfangsfrequenz des vom Lesegerät abgestrahlten HF-Signals ist. Im Modulator 4 wird die Transpondersendefrequenz mit den Daten des Nutz speichers 5 moduliert und von dem Datensender 7 auf die Antennenanordnung 1 zur Abstrahlung geleitet.The transponder further includes a NEN-housed by the RF energy powered power supply part 2, a frequency divider 3, a modulator 4, a useful memory 5 whose memory contents can be changed and the Datensen. 7 The frequency divider 3 generates the transponder sensor frequency which is expediently half the reception frequency of the RF signal emitted by the reader. In the modulator 4 , the transponder transmission frequency is modulated with the data of the useful memory 5 and passed from the data transmitter 7 to the antenna arrangement 1 for radiation.
Gemäß der Erfindung ist nun in dem Transponder ein weite rer Speicher als Codespeicher 6 vorgesehen, der zweckmäßig ebenfalls auf dem Chip integriert ist und der Gleichstrom mäßig ebenfalls von dem Stromversorgungsteil 2 versorgt wird. Der Speicherinhalt des Codespeichers 6 ist nicht auslesbar. Er hat die Wirkung eines Filters derart, daß ein mit einem Codevermerk versehenes ankommendes Signal zur Veränderung des Speicherinhalts des Nutzspeichers 5 nur dann eine Veränderung des Nutzspeicherinhalts bewirken kann, wenn der Codevermerk des Veränderungssignals von dem Speicherinhalt des Codespeichers 6 akzeptiert wird.According to the invention, a wide rer memory is now provided as code memory 6 in the transponder, which is also advantageously integrated on the chip and the direct current is also moderately supplied by the power supply part 2 . The memory content of the code memory 6 cannot be read out. It has the effect of a filter such that an incoming signal provided with a code note for changing the memory content of the useful memory 5 can only cause a change in the useful memory content if the code note of the change signal is accepted by the memory content of the code memory 6 .
Der Speicherinhalt des Code-Speichers 6 ist nicht ausles bar, d. h. die Sendefrequenz des Transponders ist mit dem Inhalt des Codespeichers 6 nicht modelierbar. Dagegen kann es zweckmäßig sein, daß der Speicherinhalt des Codespei chers 6 durch ein ankommendes Signal ein oder mehrere Male verändert werden kann und zu einem gewünschten Zeitpunkt durch ein entsprechend codiertes ankommendes Signal eine weitere Veränderung des Codespeichereinhalts blockiert wird.The memory contents of the code memory 6 is not ausles bar, ie the transmission frequency of the transponder is not modelierbar with the contents of the code memory. 6 In contrast, it may be expedient that the memory content of the Codespei chers 6 can be changed one or more times by an incoming signal and at a desired time a further change in the code memory content is blocked by an appropriately coded incoming signal.
Der Codespeicher 6 kann z. B. als ein laserprogrammiertes Diodenarray mit Filterfunktionen (z. B. Komperator) reali siert sein. Ein Vorteil des Codespeichers 6 besteht darin, daß er einfach integrierbar ist und zum Betrieb wenig Strom bracht. Dies ist für einen derartigen Transponder, der seine Gleichstromenergie aus dem ankommenden HF-Signal bezieht, äußerst wichtig, denn die praktische Einsatzfä higkeit eines solchen Transponders wird wesentlich erwei tert, wenn das Lesegerät einen größeren Abstand vom Trans ponder haben kann. Denn andererseits darf die vom Lesege rät abgestrahlte HF-Energie nicht so groß sein, daß sie schädlich sein kann.The code memory 6 can e.g. B. as a laser-programmed diode array with filter functions (z. B. comparator) be realized. An advantage of the code memory 6 is that it is easy to integrate and requires little current to operate. This is extremely important for such a transponder, which draws its direct current energy from the incoming RF signal, because the practical usability of such a transponder is substantially expanded when the reader can have a greater distance from the trans ponder. On the other hand, the RF energy emitted by the reader must not be so great that it can be harmful.
