Abstract

The identification system is in the form of a receiver that has two coils (10,12) within a common plane (18). The coils both act as transmitters that handle the same signals and have axes (14,16) that produce field lines (24). The field strength in the near field of the coils is amplified. At a distance the field lines density is reduced and the transmission signals are attenuated in the distant field.

Description

Die Erfindung betrifft eine Vorrichtung zur Identifizierung von an sportlichen Wettbewerben teilnehmenden Personen oder Tieren nach dem Oberbegriff des Anspruchs 1.The invention relates to a device for identification by people participating in sporting competitions or Animals according to the preamble of claim 1.

Es ist aus der DE 42 40 879 Al bekannt, Brieftauben mit einem Transponder zu beringen, der einen nichtlöschbaren und einen löschbaren Speicher aufweist. Im nichtlöschbaren Speicher sind die eine Brieftaube identifizierenden Daten permanent gespeichert, die vom Feld einer Antenne abrufbar sind. Bei einem Brieftaubenwettbewerb wird jede Taube über eine sogenannte Vereinsantenne geführt. Hierbei wird der die Taube identifizierende Identitätscode des nichtlöschbaren Speichers abgelesen und danach durch einen Zufallsgenerator ein Zufallscode erzeugt, der über die Vereinsantenne abgestrahlt wird und der im löschbaren Speicher gespeichert wird. In einem Registriergerät wird der Identitätscode jeder Taube und der der Taube zugeordnete Zufallscode gespeichert. Kommt die Taube am Taubenschlag an, durchwandert sie das Feld einer Schlagantenne, welche den Identitätscode und den Zufallscode aus den Speichern abliest, die zusammen mit der Ankunftszeit in einem weiteren Registriergerät gespeichert werden.It is known from DE 42 40 879 Al, homing pigeons with a Ring transponder, one non-erasable and one has erasable memory. In non-erasable memory the data identifying a carrier pigeon is permanent stored that can be called up from the field of an antenna. At In a racing pigeon competition, every pigeon is given a so-called Club antenna led. Here is the pigeon Identifying code of non-erasable memory read and then a random code by a random number generator generated, which is radiated via the club antenna and which is stored in the erasable memory. In a registration device the identity code of each pigeon and that of the Pigeon assigned random code saved. If the pigeon comes on Dovecote, it wanders through the field of a field antenna, which the identity code and the random code from the Save reads that along with the arrival time in one additional registration device can be saved.

Der von der Vereinsantenne abgestrahlte Zufallscode kann über einen Empfänger, der auf die Sendefrequenz der Vereinsantenne abgestimmt ist, beispielsweise auf 125 kHz empfangen und aufgezeichnet werden. Da die Brieftaubenzüchter die Identitätscodes ihrer Brieftauben kennen, ist es für einen Brieftaubenzüchter nur noch erforderlich, die Reihenfolge zu ermitteln, in welcher seine Brieftauben über die Vereinsantenne geführt werden. Es ist ihm dann möglich, den Identitätscodes den jeweils vergebenen Zufallscode zuzuordnen. Er kann diese Daten dann in sein Registriergerät eingeben und damit eine frühere Ankunftszeit seiner Tauben simulieren. Diese Manipulation ist vor dem Hintergrund hoher Wetteinsätze bei Brieftaubenwettflügen zu sehen.The random code emitted by the club antenna can be via a receiver on the transmission frequency of the club antenna is tuned, for example received and recorded at 125 kHz become. As the pigeon fancier the identity codes knowing their homing pigeons, it is for a homing pigeon fancier only necessary to determine the order in which his racing pigeons on the club antenna be performed. It is then possible for him to use the identity codes assign the random code assigned in each case. He can do this Then enter the data in his registration device and thus one simulate the earlier arrival time of his pigeons. This manipulation is against the background of high stakes in racing pigeon races to see.

Um das "Abhören" der Datenübertragung beim Einkorben zu erschweren, wird in der DE 195 28 279 C1 vorgeschlagen, mindestens während der Dauer der Abstrahlung des Zufallscodes durch eine weitere Antenne ein Störsignal im gleichen Frequenzbereich abzustrahlen. Das über die weitere Antenne abgestrahlte Störsignal überlagert den von der Vereinsantenne abgestrahlten Zufallscode. Da sich die Brieftauben während der Erzeugung des Zufallscodes auf der Vereinsantenne befinden und somit der Abstand zwischen dem Transponder und der Vereinsantenne sehr gering ist, soll die Eingabe des Zufallscodes in den löschbaren Speicher nicht vom Störsignal beeinflußt werden. Denn es wird unterstellt, daß die Feldstärke der Vereinsantenne im Bereich des Transponders wesentlich höher als die Feldstärke des Störsignals in der Nähe des Transponders ist, wenn eine Taube sich auf der Vereinsantenne befindet.To make it more difficult to "eavesdrop" on the data transfer when basketing, is proposed in DE 195 28 279 C1, at least during the duration of the random code emission by an additional antenna an interference signal in the same frequency range to emit. That radiated over the further antenna Interference signal is superimposed on that radiated by the club antenna Random code. Since the homing pigeons during the Generation of the random code are on the club antenna and thus the distance between the transponder and the club antenna is very small, the input of the random code not affected by the interference signal in the erasable memory become. Because it is assumed that the field strength the club antenna in the area of the transponder much higher than the field strength of the interference signal in the vicinity of the transponder is when a pigeon is on the club antenna.

Ein Problem besteht dann, wenn das Trägersignal des Schreib-Lesegerätes getastet wird und die Länge der Trägerpausen zur Informationsvermittlung genutzt wird. Selbst wenn das Störsignal eine wesentlich geringere Feldstärke als der Träger des Nutzsignal besitzt, kann diese Feldstärke ausreichen, die Erkennung der Trägerpausen und damit die Informationsvermittlung zu stören. Damit dürfte eine praktikable Ausführung der Lösung eine Abschirmung der Vereinsantenne von der weiteren Antenne oder einen großen Abstand der Antennen erforderlich machen. Hierdurch reduziert sich aber die Sicherheit gegen unerwünschtes "Abhören".A problem arises when the carrier signal of the read / write device is keyed and the length of the carrier breaks Information transfer is used. Even if the interference signal a significantly lower field strength than the carrier of the Has a useful signal, this field strength can be sufficient, the detection the carrier breaks and thus the information transfer disturb. Thus, a practicable execution of the Solution shielding the club antenna from the other Antenna or a large distance between the antennas is required do. However, this reduces security against unwanted "eavesdropping".

Die bekannte Lösung benötigt neben der weiteren Antenne auch einen weiteren Sender und einen Signalgenerator. Außerdem muß das Schreib-Lesegerät mit dem weiteren Sender gekoppelt sein, damit dieser Sender beim Auslesen des Speichers des Transponders abgeschaltet wird, da er andernfalls die sehr viel geringeren Feldstärkeschwankungen beim Lesebetrieb im Vergleich zum Sendebetrieb störend überlagern würde.In addition to the further antenna, the known solution also requires another transmitter and a signal generator. In addition, must the read / write device can be coupled to the further transmitter, so that this transmitter when reading out the memory of the transponder is switched off, otherwise it will be the much smaller ones Field strength fluctuations in reading operation in comparison would interfere with broadcasting.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zur Identifizierung von an sportlichen Wettbewerben teilnehmenden Personen oder Tieren dahingehend zu verbessern, daß die Sicherheit gegen Abhören ohne störende Beeinflussung des Datenaustausches zwischen Schreib-Lesegerät und Transponder verbessert wird.The invention has for its object a device to identify those taking part in sporting competitions To improve people or animals in such a way that the security against eavesdropping without disturbing the Data exchange between read / write device and transponder is improved.

Diese Aufgabe wird bei einer Vorrichtung zur Identifizierung von an sportlichen Wettbewerben teilnehmenden Personen oder Tieren durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale gelöst. Weiterbildungen und vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.This task is performed in an identification device by people participating in sporting competitions or Animals by those specified in the characterizing part of claim 1 Features resolved. Training and advantageous Refinements result from the subclaims.

Im Unterschied zum Stand der Technik wird den Strahlern der Antennenanordnung bei der Erfindung dasselbe Sendesignal zugeführt. Das bedeutet, daß keinerlei Fremdsignale erzeugt werden, die die Datenübertragung von Schreib-Lesegerät zum Transponder beeinträchtigen könnten. Dies gilt sowohl für den Fall, daß die Informationen in den Pulsen, in den Pausen, kombiniert in den Pulsen und den Pausen oder auch in einer analogen Modulation des Trägers liegen. Da es sich um dasselbe Sendesignal handelt, besteht zwangsläufig Synchronität zwischen den von den Strahlen abgestrahlten Signalen, so daß sie sich im Fernfeld bei entsprechender Phasenlage gegenseitig wirksam auslöschen können. Mit "auslöschen" ist hierbei eine solche Dämpfung gemeint, daß das Signal im Fernfeld unterhalb des üblichen Störpegels und Rauschens liegt, so daß es nicht mehr gelesen werden kann. Die Phasenlage ist dabei starr, so daß die Dämpfung stabil ist.In contrast to the prior art, the emitters are Antenna arrangement in the invention supplied the same transmission signal. This means that no external signals are generated be the data transfer from read / write device to Could affect transponders. This applies to both Case that the information in the pulses, in the pauses, combined in the pulses and the breaks or in one analog modulation of the carrier. Since it's the same thing Transmitted signal, there is necessarily synchronicity between the signals emitted by the beams, so that they are mutually distant in the far field with the appropriate phase position can effectively wipe out. With "delete" is here such attenuation means that the signal in the far field below of the usual interference level and noise, so that it can no longer be read. The phase position is there rigid so that the damping is stable.

Ein weiterer Vorteil der Erfindung besteht darin, daß sie nicht nur beim Beschreiben des Transponders, sondern auch beim Kontrollesen wirksam ist.Another advantage of the invention is that it not only when describing the transponder, but also is effective in the control reading.

Weiterhin können die Strahler so ausgebildet sein, daß sich ihre Feldkomponenten im resultierenden Nahfeld verstärken. Dies ermöglicht es, die für eine sichere Energieübertragung und Datenübertragung des Schreib-Lesegerätes zum Transponder nötige Sendeleistung gegenüber dem Betriebsfall mit nur einer Antenne reduziert werden kann.Furthermore, the emitters can be designed so that amplify their field components in the resulting near field. This allows for safe energy transfer and data transfer from the read / write device to the transponder necessary transmission power compared to the operating case with only one Antenna can be reduced.

Vorzugsweise umfassen die Strahler Spulen oder Spulenbereiche, die nebeneinander angeordnet und gegenphasig gespeist sind. Die Spulen oder Spulenbereiche können ferner achsparallel angeordnet sein. Darüberhinaus können die Spulen oder Spulenbereiche in einer gemeinsamen, quer zur Spulenachse verlaufenden Ebene liegen.The radiators preferably comprise coils or coil areas, which are arranged side by side and fed in opposite phases are. The coils or coil areas can also be axially parallel be arranged. In addition, the coils or Coil areas in a common, transverse to the coil axis level.

Diese Maßnahmen ermöglichen es, die Anordnung und Ausrichtung der Spulen oder Spulenbereiche so zu optimieren, daß ihre Abstrahlung symmetrisch erfolgt und damit eine maximale Verstärkung des Nahfeldes und eine maximale Dämpfung des Fernfeldes eintritt.These measures allow the arrangement and alignment to optimize the coils or coil areas so that their radiation takes place symmetrically and thus a maximum gain of the near field and maximum attenuation of the far field entry.

Bei einer bevorzugten Ausführungsform weisen die Strahler eine gemeinsame Spule auf, die in zwei, zusammen eine 8 bildende Spulenbereiche umgeformt sind. Da die beiden Spulenbereiche aus ursprünglich einer gemeinsamen Spule gebildet sind, ist ein gleichartiger Aufbau und damit eine optimale Symmetrie gewährleistet. Ferner wird die Herstellung vereinfacht und elektrische Kontakte vermieden, da die beiden Spulenbereiche zwangsläufig galvanisch miteinander verbunden sind.In a preferred embodiment, the emitters have a common coil on, in two, together forming an 8 Coil areas are formed. Because the two coil areas are originally formed from a common coil, is a similar structure and therefore an optimal symmetry guaranteed. Manufacturing is also simplified and avoided electrical contacts since the two coil areas are necessarily galvanically connected to each other.

Die Spulen oder Spulenbereiche können von einem Gehäuse umgeben sein, das in das Innere einer der Spulen oder Spulenbereiche eingezogen ist. Dort kann ein räumlich definiertes Programmierfeld für eine zuverlässige elektromagnetische Koppelung beim Eintauchen eines Transponders mit diesem gebildet sein. The coils or coil areas can be surrounded by a housing be that inside one of the coils or coil areas has moved in. There can be a spatially defined one Programming field for reliable electromagnetic coupling formed when immersing a transponder be.

Hierdurch wird ausschließlich eine der Spulen für die Daten- und Energieübertragung zum Transponder ausgebildet und es wird so vermieden, daß beim Heranführen des Transponders an die Strahleranordnung sowie bei Entfernen davon die Transponder nacheinander in die Felder der Strahler eintauchen und dadurch wiederholt eine Daten- und Energieübertragung stattfindet.As a result, only one of the coils for the data and Energy transfer to the transponder trained and it is avoided so that when moving the transponder on the emitter arrangement and, when removed, the transponder immerse one after the other in the fields of the spotlights and this results in repeated data and energy transmission.

Fig. 1 zeichnet eine schematische Ansicht einer Strahleranordnung der erfindungsgemäßen Vorrichtung. Die Strahleranordnung umfaßt zwei Spulenbereiche 10, 12, die nebeneinander angeordnet und achsparallel ausgerichtet sind und in einer gemeinsamen, quer zu den Spulenachsen 14, 16 verlaufenden Ebene 18 liegen. Die Spulenbereiche 10, 12 werden gegenphasig mit dem Sendesignal gespeist. Dies führt dazu, daß die magnetischen Feldkomponenten des elektromagnetischen Feldes durch die Querschnitte beider Spulenbereiche 10, 12 verlaufen und geschlossene Feldlinien 24 bilden. Dies bedeutet, daß sich die Feldstärke im Nahfeld der Spulenbereiche 10, 12 verstärkt, während die Feldliniendichte gleichzeitig im Fernfeld stark abnimmt, also eine starke Dämpfung des Sendesignals im Fernfeld eintritt.1 shows a schematic view of a radiator arrangement the device according to the invention. The spotlight arrangement comprises two coil areas 10, 12, which are arranged side by side and aligned axially and in a common, plane extending transversely to the coil axes 14, 16 18 lie. The coil areas 10, 12 are out of phase with fed the transmission signal. This leads to the magnetic Field components of the electromagnetic field the cross sections of both coil areas 10, 12 and form closed field lines 24. This means that the field strength in the near field of the coil regions 10, 12 is increased, while the field line density is simultaneously in the far field decreases sharply, i.e. a strong attenuation of the transmission signal in the Fernfeld enters.

Wie die schematische Ansicht der Strahleranordnung auf den Spulencuerschnitt gemäß Fig. 2 zeigt, bilden die Strahler eine gemeinsame Spule, die in zwei, zusammen eine 8 bildende Spulenbereiche 10, 12 umgeformt ist. Die Spulenbereiche 10, 12 sind dadurch spiegelsymmetrisch zueinander geformt und gleichzeitig gegenphasig gepolt, wenn die elektrisch in Reihe geschalteten Spulenbereiche 10, 12 an die Schreib-Lesevorrichtung angeschlossen werden.How the schematic view of the radiator arrangement on the 2 shows, the radiators form a common coil, which in two, together forming an 8 Coil areas 10, 12 is formed. The coil areas 10, 12 are thereby mirror-symmetrically shaped and poled in opposite phase at the same time when the electrical in series switched coil areas 10, 12 to the read / write device be connected.

Die beiden Spulenbereiche 10, 12 sind von einem gemeinsamen Gehäuse 20 umgeben, das eine Einschnürung aufweist, die in das Innere des einen Spulenbereichs 10 eingezogen ist. Diese Einschnürung bildet dort ein räumlich definiertes Programmierfeld 22 und erlaubt so eine zuverlässige elektromagnetische Kopplung, wenn ein Transponder in die Einschnürung eingetaucht wird. Dadurch wird verhindert, daß eine eventuelle unvollständige Datenübertragung stattfindet, wenn der Transponder beim Annähern oder Entfernen vom Progranmierfeld 22 an dem anderen Spulenbereiche 12 entlang bewegt wird.The two coil areas 10, 12 are of a common one Surround housing 20, which has a constriction, which in the inside of one coil area 10 is drawn in. This Constriction forms a spatially defined programming field there 22, allowing reliable electromagnetic Coupling when a transponder is immersed in the constriction becomes. This prevents a possible incomplete data transfer takes place when the transponder when approaching or moving away from the programming field 22 is moved along the other coil area 12.
