Abstract

The invention relates to the coupling of a sensor element to a transponder, the connection of said sensor element to the transponder being achieved by capacitive or inductive coupling. This enables any separation layer that may lie between the sensor element and the transponder to be retained, allowing the invention to be advantageously used in gas and liquid-tight containers, such as tyres. In addition, electrically non-conductive materials of the object to be measured can be used as a dielectric for the capacitive coupling and electrically conductive parts can form part of a conductor loop for the inductive coupling.

Description

ANKOPPLUNG EINES SENSORELEMENTS AN EINEN TRANSPONDER CONNECTING A SENSOR ELEMENT TO A TRANSPONDER
Die Erfindung betrifft eine Ankopplung eines Sensorelements an einen Transponder.The invention relates to a coupling of a sensor element to a transponder.
Die drahtlose Abfrage der relevanten elektrischen Größen eines Transponders mit einem passenden Lesegerät stellt eine Grundfunktion der Funksensorik dar. Den abzufragenden elektrischen Größen wird die Information über die zu messenden physikalischen Größen durch geeignete Sensorelemente aufgeprägt.The wireless interrogation of the relevant electrical variables of a transponder with a suitable reading device represents a basic function of the radio sensor system. The electrical variables to be queried are imprinted with the information about the physical variables to be measured by suitable sensor elements.
In verschiedenen Einsatzbereichen von berührungsloser Funksensorik fällt der Ort der Messgrößenaufnahme (durch eines oder mehrere Sensorelemente) nicht mit der zur Funkabfrage durch das Lesegerät geeigneten Transponderposition zusammen. Die Sensorelemente sind dann im allgemeinen leitungsgebunden an die anderen funktionellen Komponenten des Transponders (insbesondere die über Funk mit dem Lesegerät in Verbindung stehenden Einheiten des Transponders) angekoppelt.In various areas of application of non-contact radio sensors, the location of the measurement variable recording (by one or more sensor elements) does not coincide with the transponder position suitable for radio interrogation by the reading device. The sensor elements are then generally wired to the other functional components of the transponder (in particular the units of the transponder which are connected to the reader by radio).
In vielen Anwendungen ist die direkte, leitungsgebundene Ankopplung des Sensorelements (8) an den Transponder nicht möglich ohne die Funktion des zu vermessenden Objekts zu beeinträchtigen, da z.B. eine zwischen Transponder und Sensor liegende, funktional essentielle Trennwand, Membran, Beschichtung oder dgl. durchdrungen und damit beschädigt werden müsste.In many applications, the direct, line-connected coupling of the sensor element (8) to the transponder is not possible without impairing the function of the object to be measured, e.g. a functionally essential partition wall, membrane, coating or the like located between the transponder and the sensor would have to be penetrated and thus damaged.
Der Erfindung liegt die Aufgabe zugrunde, eine Ankopplung der eingangs genannten Art anzugeben, welche die Funktion des zu vermessenden Objekts nicht beeinträchtigt.The invention has for its object to provide a coupling of the type mentioned, which does not affect the function of the object to be measured.
Diese Aufgabe wird sowohl dadurch gelöst, dass die Anbindung des Sensorelements an den Transponder durch kapazitive Ankopplung realisiert wird, als auch dadurch, dass die Anbindung des Sensorelements an den Transponder durch induktive Ankopplung realisiert wird.This task is solved in that the connection of the sensor element to the Transponder is realized by capacitive coupling, as well as in that the connection of the sensor element to the transponder is realized by inductive coupling.
Es ist besonders vorteilhaft, dass als Sensorelement eine in ihrem Wert von der jeweiligen Messgröße abhängige Kapazität verwendet wird. Alternativ kann es auch vorteilhaft sein, dass als Sensorelement eine in ihrem Wert von der jeweiligen Messgröße abhängige Induktivität oder ein Ohmscher Widerstand verwendet wird.It is particularly advantageous that a capacitance whose value depends on the respective measured variable is used as the sensor element. Alternatively, it may also be advantageous to use an inductance or an ohmic resistance which is dependent on the respective measured variable in terms of its value.
Bei Anwendungen, bei welchen es auf die Dichtheit eines Hohlkörpers ankommt oder die mechanische Stabilität des Körpers nicht beeinträchtigt werden soll, besteht eine bevorzugte Weiterbildung der Erfindung darin, dass die Anbindung des Sensorelements an den Transponder ohne vollständige oder teilweise mechanische Durchdringung einer zwischen Transponder und Sensorelement liegenden Trennschicht realisiert wird. Typische Beispiele sind Fahrzeug- oder Flugzeugreifenreifen, die nachfolgend allgemein als Reifen bezeichnet werden.In applications in which the tightness of a hollow body is important or the mechanical stability of the body should not be impaired, a preferred development of the invention is that the connection of the sensor element to the transponder without complete or partial mechanical penetration of a between the transponder and the sensor element lying separation layer is realized. Typical examples are vehicle or aircraft tire, which are generally referred to below as tires.
Eine vorteilhafte Weiterbildung der Erfindung liegt darin, dass zumindest das Sensorelement oder der Transponder an gegenüberliegenden Seiten einer Trennschicht angeordnet sind. Eine für viele Anwendungsfälle sehr gut geeignete Alternative besteht darin, dass eines dieser Elemente bevorzugt entweder an der Oberfläche oder im Inneren der Trennschichten angeordnet sein.An advantageous development of the invention is that at least the sensor element or the transponder are arranged on opposite sides of a separating layer. An alternative which is very suitable for many applications is that one of these elements is preferably arranged either on the surface or in the interior of the separating layers.
Eine bevorzugte Verwendung der Erfindung liegt darin, dass die Messgrößenaufnahme durch Sensorelemente im zumindest teilweise mit gas- oder flüssigkeitsgefüllten Innenraum eines Behältnisses realisiert wird.A preferred use of the invention is that the measurement variable recording is implemented by sensor elements in the interior of a container that is at least partially filled with gas or liquid.
Wenn eine Trennschicht aus elektrisch isolierendem Material vorhanden ist, wird die kapazitive Ankopplung besonders einfach dadurch, dass das Dielektrikum der kapazitiven Ankopplung zumindest teilweise von der mechanischen Trennschicht gebildet wird.If a separating layer made of electrically insulating material is present, the capacitive coupling is particularly simple in that the dielectric of the capacitive coupling is at least partially formed by the mechanical separating layer.
Ist in der Trennschicht ein elektrisch leitfähiger Leiter vorhanden, wird die induktive Ankopplung besonders einfach dadurch, dass zumindest ein Teil einer Leiterschleife der induktiven Ankopplung von dem vorhandenen Leiter gebildet wird.If an electrically conductive conductor is present in the separating layer, the inductive coupling is particularly simple in that at least part of a conductor loop of the inductive coupling is formed by the existing conductor.
Beim Einsatz der Erfindung bei einem Reifen mit Stahlgürtel ist es besonders vorteilhaft, dass der Stahlgürtel als Leiterschleife der induktiven Ankopplung verwendet wird. Zusätzlich oder alternativ ist es zweckmäßig, dass eine Leiterschleife durch Einvulkanisierung in einem Reifen angeordnet wird.When using the invention in a tire with a steel belt, it is particularly advantageous that the steel belt is used as a conductor loop of the inductive coupling. Additionally or alternatively, it is expedient for a conductor loop to be arranged in a tire by vulcanization.
Nachfolgend wird die Erfindung anhand von zwei in der Zeichnung dargestellten Ausführungsbei- . spielen weiter erläutert. Es zeigen schematisch:The invention is described below with reference to two exemplary embodiments shown in the drawing. play further explained. They show schematically:
"Fig. 1 ein Blockschaltbild eines ersten Beispiels einer Ankopplung eines Sensorelements (8) an einen Transponder auf der Grundlage einer kapazitiven Kopplung; und Fig. 2 ein Blockschaltbild eines zweiten Beispiels auf der Grundlage einer induktiven Kopplung.1 shows a block diagram of a first example of a coupling of a sensor element (8) to a transponder on the basis of a capacitive coupling; and FIG. 2 shows a block diagram of a second example on the basis of inductive coupling.
Gemäß Fig. 1 ist ein Sensorelement an einen Transponder 5 drahtlos angebunden, d.h. das Sensorelement 8 und der Transponder 5 sind nicht leitungsverbunden. Der Ausgang des Sensorelements 8 ist vielmehr mit dem Eingang des Transponders 5 über einen Kopplungskondensatoren 7, 7' kapazitiv gekoppelt. Das Sensorelement 8 kann abhängig von der zu messenden Größe als ohmscher Widerstand, als Kapazität oder als Induktivität ausgebildet sein.1, a sensor element is wirelessly connected to a transponder 5, i.e. the sensor element 8 and the transponder 5 are not line-connected. The output of the sensor element 8 is rather capacitively coupled to the input of the transponder 5 via a coupling capacitor 7, 7 '. Depending on the size to be measured, the sensor element 8 can be designed as an ohmic resistance, as a capacitance or as an inductor.
Der Transponder 5 ist über eine Antenne 6 mit einer Antenne 4 eines separaten Schreib- ZLesegerät 1 verbunden, das einen Sender 2 und einen Empfänger 3 aufweist. Über das Schreib- ZLesegerät 1 können Messdaten des Sensorelements 8 leitungslos ausgelesen werden. Das Schreib-ZLesegerät 1 ist ortsfest angeordnet, während sich Sensorelement 8 sowie Transponder 5 auf einem bewegten Messobjekt 13 befinden.The transponder 5 is connected via an antenna 6 to an antenna 4 of a separate write / read reader 1 which has a transmitter 2 and a receiver 3. Measurement data of the sensor element 8 can be read out in a line-free manner via the write / read reader 1. The write / read reader 1 is arranged in a fixed position, while the sensor element 8 and transponder 5 are located on a moving measurement object 13.
In dem dargestellten Beispiel sind das Sensorelement 8 und der Transponder 5 durch eine Membran 9 oder ein anderes elektrisch nicht leitendes Material getrennt. Die Membran 9 oder das andere nichtleitende Material bilden dabei ein zwischen den Platten des Kopplungskondensator 7 befindliches Dielektrikum, das die Kopplungskapazitäten beeinflusst.In the example shown, the sensor element 8 and the transponder 5 are separated by a membrane 9 or another electrically non-conductive material. The membrane 9 or the other non-conductive material form a dielectric located between the plates of the coupling capacitor 7, which influences the coupling capacitances.
Eine derartige Konstellation ist bei einer Platzierung des Sensorelements 8 innerhalb eines Körpers, beispielsweise eines Fahrzeugreifens, gegeben. Zur Messung von Temperatur, Deformation oder anderen physikalischen Größen mit geeigneten Sensorelementelementen in der Karkasse des Fahrzeugreifens wird dabei eine Platte des Kopplungskondensators 7 an der Innenseite des Reifens angeordnet und die zweite Platte in einem gewissen Abstand zur ersten vollständig im Reifenmaterial integriert. Die abdichtende innere Schicht des Reifens bleibt dabei unversehrt. Das ist wegen der hier aufgebrachten Butylschicht sehr wichtig, da diese unter anderem maßgeblich für die Dichtheit eines Reifens verantwortlich ist. Das zwischen den Kondensatorplatten liegende Reifenmaterial bildet das Dielektrikum des Koppelkondensators 7.Such a constellation is given when the sensor element 8 is placed inside a body, for example a vehicle tire. To measure temperature, deformation or other physical quantities with suitable sensor element elements in the carcass of the vehicle tire, a plate of the coupling capacitor 7 is arranged on the inside of the tire and the second plate is completely integrated in the tire material at a certain distance from the first. The sealing inner layer of the tire remains intact. This is very important because of the butyl layer applied here, as it is among other things is largely responsible for the tightness of a tire. The tire material lying between the capacitor plates forms the dielectric of the coupling capacitor 7.
In diesem Beispiel ist das Schreib-Z Lesegerät 1 in einem Fahrzeug angeordnet, so dass die Reifenmessdaten während der Fahrt zu einem Bordcomputer oder ähnlichem übermittelt werden können.In this example, the write-Z reader 1 is arranged in a vehicle, so that the tire measurement data can be transmitted to an on-board computer or the like while driving.
Fig. 2 veranschaulicht einen Anwendungsfall, bei welchem die drahtlose Anbindung des Sensorelements 8 an den Transponder 5 mittels induktiver Ankopplung 12 erfolgt. Die magnetische Verkopplung von zwei Spulen 10, .1 1 erfolgt unter Verwendung der konstruktiven Gegebenheiten des Messobjektes. Wird die Anordnung bei einem Reifen eingesetzt, befindet sich eine der Spulen 10 auf der Reifeninnenseite und die andere Spule 9 ist in das Reifenmaterial integriert. Die zweite Spule kann dabei zumindest teilweise von einem Stahlgürtel des Reifens gebildet sein.2 illustrates an application in which the sensor element 8 is wirelessly connected to the transponder 5 by means of inductive coupling 12. The magnetic coupling of two coils 10, .1 1 takes place using the structural conditions of the measurement object. If the arrangement is used in a tire, one of the coils 10 is located on the inside of the tire and the other coil 9 is integrated in the tire material. The second coil can be at least partially formed by a steel belt of the tire.
Zur Messung kommt jede beliebige physikalische Größe in Betracht, die konkrete Ausführung des messwertsensitiven Elements ist also nicht maßgeblich und hängt im allgemeinen von der interessierenden Messgröße ab. Mögliche Ausführungsformen des Sensorelements 8 sind in ihrem Wert von der jeweiligen Messgröße abhängige Kapazitäten, Induktivitäten oder ohmsche Widerstände. Any physical quantity can be considered for the measurement, so the specific design of the measurement-sensitive element is not decisive and generally depends on the measurement quantity of interest. Possible embodiments of the sensor element 8 are capacitances, inductances or ohmic resistances that are dependent on the respective measured variable.
