Description
Identifikationssystem bestehend aus einem AbfragegerätIdentification system consisting of an interrogation device
und einem Antwortgerät Die Erfindung betrifft ein Identifikationssystem nach dem Oberbegriff des Anspruchs 1.and a transponder. The invention relates to an identification system according to the preamble of claim 1.
Solche Einrichtungen dienen z. B. bei Gleisfahrzeugen zur Automatisierung des Betriebes sowie zur Sicherung des Streckennetzes.Such facilities are used for. B. in rail vehicles for automation of operation as well as to secure the route network.
In der Literatur sind ähnliche Einrichtungen bekannt.Similar devices are known in the literature.
Z. B. strahlt beim SICARID-UCL-System eine fahrzeugseitige Sendeeinrichtung eines Abfragegerätes ein hochfrequentes, gewobbeltes Abfragesignal aus, das durch frequenzselektive Reflexion mit Hilfe an einer Schiene eines Eisenbahngleises angeordneter Antwortgeräte die in diesen jeweils verschlüsselte Streckeninformation an eine Empfangseinrichtung des Abfragegerätes überträgt. Ein nach diesem Prinzip arbeitendes ähnliches Verfahren, bei dem Antwort- und Fragegerät vertauscht sind, dient z. B. zur Identifikation von Güterwagen.For example, in the SICARID-UCL system, a vehicle-side transmitter emits an interrogation device emits a high-frequency, wobbled interrogation signal that is transmitted by frequency-selective reflection with the help of a rail of a railroad track Responders send the route information encrypted in these to a receiving device of the interrogation device. One that works according to this principle similar Method in which the answering device and questioning device are interchanged, is used, for. B. for identification of freight wagons.
Der Erfindung liegt die Aufgabe zugrunde, ein weiteres System der eingangs genannten Art anzugeben, das sich durch einfachen Aufbau auszeichnet.The invention is based on the object of a further system of Specify the type mentioned at the beginning, which is characterized by its simple structure.
Die Erfindung ist im Patentanspruch 1 beschrieben. Die weiteren Ansprüche beinhalten vorteilhafte Weiterbildungen bzw. Ausführungsformen der Erfindung.The invention is described in claim 1. The other claims contain advantageous developments or embodiments of the invention.
Der Erfindung zugrunde liegt das Prinzip, daß das abfragende Gerät zwei diskrete Frequenzen abstrahlt, die vom antwortenden Gerät empfangen und mit Hilfe einer nichtlinearen Schaltungsanordnung in eine dritte Frequenz umgesetzt werden. Dieses Mischprodukt, dessen Frequenz z. B. die Summe oder die Differenz der beiden empfangenen Frequenzen sein kann, wird im Antwortgerät durch eine geeignete Modulation, z. B. ASK, mit einer Kennung versehen, die die Fahrzeuginformation bzw. die Streckeninformation enthält. Das so modulierte Signal wird vom Antwortgerät abgestrahlt und vom Abfragegerät empfangen und ausgewertet.The invention is based on the principle that the querying device emits two discrete frequencies that are received by the answering device and with Implemented into a third frequency using a non-linear circuit arrangement will. This mixed product, the frequency of which z. B. the sum or the difference of the two received frequencies is indicated in the transponder by a suitable one Modulation, e.g. B. ASK, provided with an identifier that contains the vehicle information or contains the route information. The signal modulated in this way is transmitted by the transponder emitted and received and evaluated by the interrogation device.
Bei der Realisierung des Identifikationssystems bringt die Verwendung von Frequenzen im Millimeterwellenbereich, z. B. bei 40 oder 60 GHz, besondere Vorteile, weil bei kleinen Antennenabmessungen eine hohe Strahlbündelung und damit verbunden ein hoher Wirkungsgrad bei der teistungsübertragung zwischen den beiden Geräten möglich ist. Infolge der atmosphärischen Dämpfung z. B. bei 60 GHz klingen die Signale bei weiterer Entfernung sehr rasch ab, so daß eine Störung anderer Systeme verhindert wird.When realizing the identification system brings the use of frequencies in the millimeter wave range, e.g. B. at 40 or 60 GHz, special advantages, because with small antenna dimensions a high beam bundling and associated with it a high degree of efficiency in the transfer of power between the two devices is possible. As a result of the atmospheric damping z. B. at 60 GHz the signals sound decreases very quickly with further distance, so that a disturbance of other systems is prevented will.
Ein weiterer Vorteil der hohen Strahlbüadelung ergibt sich aus der Möglichkeit, die vom Äbfragegerät abgestrahlte Leistung zum Teil zur Gleichstromversorgung des Antwortgerätes zu verwenden. Als Alternative hierfür ist auch eine Versorgung mit Solarzellen möglich.Another advantage of the high beam loading results from the Possibility to use part of the power emitted by the query device for direct current supply of the transponder. As an alternative to this, there is also a supply possible with solar cells.
Das Antwortgerät besteht vorzugsweise aus einem Hochfrequenzteil, einem Digitalteil und einer Stromversorgung, wie in der FIG. dargestellt.The transponder preferably consists of a high-frequency part, a digital part and a power supply as shown in FIG. shown.
Der Hochfrequenzteil setzt sich im wesentlichen zusammen aus einer Antenne oder einer Antennengruppe, die die zwei Signale, z. B. bei 30 GHz empfängt und das Mischprodukt wieder abstrahlt, sowie aus einem Frequenzumsetzer, der aus einem Abwärts- bzw. Aufwärtsumsetzer bestehen kann.The high-frequency part is essentially composed of one Antenna or group of antennas that transmit the two signals, e.g. B. receives at 30 GHz and emits the mixed product again, as well as from a frequency converter, which from may consist of a down converter or up converter.
Im Digitalteil befinden sich im wesentlichen eine Einrichtung zur Speicherung der Fahrzeug- bzw. Fahrortskennung sowie ein Modulator, welcher das Mischprodukt mit der entsprechenden Kennung versieht Diese Funktionen können durch ein RAM mit einem entsprechenden Adresszähler und einem vom RAM gesteuerten Schalter, der auf den Frequenzumsetzer einwirkt, ausgeübt werden. Alternativ hierzu besteht die Möglichkeit, einen Kodierschalter und Multiplexer zu verwenden. Hierbei dient der Kodierschalter als Speicher für die Kennung und der Multiplexer in Verbindung mit dem Frequenzumsetzer als Modulator.In the digital part there is essentially a device for Storage of the vehicle or driving location identification as well as a modulator, which the The mixed product is provided with the appropriate identifier. These functions can be carried out by a RAM with a corresponding address counter and a switch controlled by the RAM, acting on the frequency converter. Alternatively, there is the possibility of using a coding switch and multiplexer. This serves the coding switch as a memory for the identifier and the multiplexer in connection with the frequency converter as a modulator.
Eine vorteilhafte Variante für den Kodierschalter stellt die Verwendung eines Lochkartenlesers dar, der die Kennung aus einer auswechselbaren Lochkarte bezieht.Use is an advantageous variant for the coding switch a punch card reader, the identifier from an exchangeable punch card relates.
