Häufig ist es jedoch auch notwendig, dass in solchen Filtern für gasförmige Medien weitere auch temporäre Einflüsse wie Ansammlungen von Flüssigkeiten, z.B. sind dies bei Kraftfahrzeugen Wasseransammlungen durch die Gischt eines vorausfahrenden Fahrzeugs, detektiert werden sollen.Frequently however, it is also necessary that in such filters for gaseous media others also temporary influences like accumulations of liquids, e.g. in the case of motor vehicles, water accumulation through the Spray from a vehicle in front that is to be detected.
Der Erfindung liegt die Aufgabe zugrunde, eine Sensoranordnung der eingangs genannten Art so fortzubilden, dass eine einfache Detektion einer Vielzahl von Einflussparametern auf die Wirkung eines Filters durchführbar ist.The invention has for its object a To further develop the sensor arrangement of the type mentioned at the outset in such a way that a simple detection of a large number of influencing parameters the effect of a filter feasible is.
Vorteile der ErfindungAdvantages of invention
Eine Sensoranordnung der eingangs beschriebenen Art für ein Filterelement mit einer Detektionseinrichtung für mindestens einen die Filterwirkung beeinflussenden Parameter des Filterelements ist in vorteilhafter Weise dadurch weitergebildet, dass die Detektionseinrichtung eine optische Übertragungsstrecke enthält, die zumindest teilweise durch das Filterelement hindurchführt und/oder an ihm reflektiert wird und deren Transmissions- und/oder Reflektionswerte von der Beschaffenheit des Filterelements abhängen.A sensor arrangement of the beginning described type for a filter element with a detection device for at least is a filter element parameter influencing the filter effect further developed in an advantageous manner that the detection device an optical transmission link contains which at least partially passes through the filter element and / or is reflected on it and its transmission and / or reflection values depend on the nature of the filter element.
Das vorgeschlagene System arbeitet auf einfache Weise nach einem optischen Verfahren, bei dem die optisch relevanten und sich ändernden Eigenschaften des Filtermediums ausgenutzt werden. Bevorzugt ist die erfindungsgemäße Anordnung bei einem Luftfilter im Ansaugsystem eines Verbrennungsmotors für ein Kraftfahrzeug anwendbar; jedoch ist auch eine Auswertung einer besonders behandelten Stelle eines Filterpapiers oder an einer anderen Stelle im Gehäuse oder Zuleitungsbereich im Einflussbereich der Motorzuluft des Kraftfahrzeugs denkbar.The proposed system works in a simple manner using an optical method in which the optical relevant and changing Properties of the filter medium can be exploited. Is preferred the arrangement according to the invention in an air filter in the intake system of an internal combustion engine for a motor vehicle applicable; however, an evaluation of a specially treated is also Place of filter paper or another place in the housing or Supply area in the area of influence of the engine supply air of the motor vehicle conceivable.
Die Detektionseinrichtung enthält einen optischen Sender und einen optischen Empfänger, wobei zur Messung der Transmission der Sender und der Empfänger jeweils gegenüberliegend beidseitig einer Filterlage des Filterelements angeordnet sind. Alternativ oder in Kombination kann die Detektionseinrichtung auch einen optischen Sender und einen optischen Empfänger enthalten, die zur Messung der Reflektion in einem korrespondierenden Winkel einseitig an einer Filterlage des Filterelements angeordnet sind. Das Filterelement kann beispielsweise aus zick-zackförmig gefalteten Filterlagen mit dazwischenliegenden Sendern und Empfängern für die optische Übertragungsstrecken bestehen.The detection device contains one optical transmitter and an optical receiver, being used to measure the Transmission of the transmitter and the receiver opposite each other are arranged on both sides of a filter layer of the filter element. alternative or in combination, the detection device can also be an optical device Transmitter and an optical receiver included to measure the reflection at a corresponding angle are arranged on one side on a filter layer of the filter element. The filter element can, for example, be made from zigzag pleats Filter layers with transmitters and receivers in between for the optical transmission links consist.
Insbesondere zur Detektion von Feuchtigkeit oder Flüssigkeit im Filterelement können die entsprechenden Filterlagen im Bereich der optischen Übertragungsstrecke in vorteilhafter Weise mit einer Beschichtung versehen sein, die sich bei Kontakt mit der Feuchtigkeit oder der Flüssigkeit verfärbt und damit die spektrale Transmissionsoder Reflektionsfähigkeit des Filterelements beeinflusst. Hiermit ist vor allem die Detektion von Wasseransammlungen oder Feuchtigkeit im Filter eines Fahrzeugs, z.B.In particular for the detection of moisture or liquid in the filter element the corresponding filter layers in the area of the optical transmission path advantageously be provided with a coating that contact with moisture or liquid discolored and thus the spectral transmission or reflectivity of the filter element influenced. This is above all the detection of water accumulation or moisture in the filter of a vehicle, e.g.
durch die Gischt eines vorausfahrenden Fahrzeugs erzeugt, auf einfache Weise ermöglicht.through the spray of a vehicle in front generated, made possible in a simple manner.
Die Detektionseinrichtung arbeitet zum Beispiel im infraroten oder einem sonstigen auswertbaren Bereich des Lichts und es ist eine entsprechende Ausgabeeinheit für ein elektrisches Detektionssignal vorhanden. Die Auswertung kann dann auf einfache Weise durch eine intelligente Elektronik vorgenommen werden und kann mit einem elektronischen Bussystem, z.B. einem fahrzeugeigenen Bussystem, zur Auswertung der Detektionsdaten und zur gemeinsamen Verarbeitung mit anderen physikalischen Parametern verknüpft werden. Hierbei können weitere bereits vorhandene Daten zur Kalibrierung genutzt werden, wie z.B. Temperaturdaten, Informationen über Serviceintervalle des Filterelements, Luftdurchsatz des Motors bzw. des Filterelements, und ggf. auch Signale des Scheibenwischers oder eines Regensensors um Informationen über eine mögliche Durchfeuchtung des Filterelements zu erhalten.The detection device works for example in the infrared or other evaluable range of light and it is a corresponding output unit for an electrical Detection signal available. The evaluation can then be carried out in a simple manner through intelligent electronics and can be done with an electronic bus system, e.g. an in-vehicle bus system, for evaluating the detection data and for joint processing linked with other physical parameters. Here, more existing data can be used for calibration, e.g. Temperature data, information about service intervals of the filter element, air throughput of the engine or the filter element, and possibly also signals from the windshield wiper or a rain sensor for information about a possible To get moisture through the filter element.
Diese Daten können dann auf einfache Weise durch die Elektronik erfasst und ausgewertet werden und es ist weiterhin auch eine Auswertung unter Hinzuziehung anderer Auswertealgorithmen mit einer Auswertung zum Beispiel auch der Schadstoffkonzentration der zu filternden Luft möglich. Es ist hierbei auch möglich eine schadstoffsensitive Beschichtung auf dem Filterpapier vorzusehen, dessen Beeinflussung aufgrund der Schadstoffeinwirkung erfasst werden kann.This data can then be recorded and evaluated in a simple manner by the electronics, and it is also an evaluation using other evaluation algorithms with an evaluation, for example, also of the pollutant concentration of the air to be filtered possible. It is also possible to provide a pollutant-sensitive coating on the filter paper, the influence of which can be detected due to the effects of the pollutants.
