Abstract
Geruchsmessanordnung, bestehend aus Gassensor, Aktor, Computer und Probenvorbereitung, dadurch gekennzeichnet, dass diese so aufgebaut und verkoppelt sind, dass sie bei Beaufschlagung durch einen Geruch als steuerbares, regelbares, optimierbares und objekterkennendens Ganzes reagieren.Odor measurement arrangement consisting of gas sensor, actuator, computer and sample preparation, characterized in that they are constructed and coupled so that they react when acted upon by an odor as a controllable, controllable, optimizable and object-recognizing whole.
Description
Das Gebrauchsmuster wird in der Geruchsmesstechnik und Geruchsklassifizierung angewendet.The utility model is used in odor measurement and odor classification.
Bekannt sind Messanordnungen als so genannte elektronische Nasen, die Gerüche als komplexe Gasgemische detektieren. Die dazu verwendeten sensitiven gasempfindlichen Anordnungen verändern ihre Parameter. Das wird elektronisch, optisch oder anderswie geeignet festgestellt und als Information über den Geruch mitgeteilt. Beispiele sind in den Patentschriften
In der Praxis bei der Geruchsfeststellung von Krankheiten, Lebensmittelqualitäten, Umweltgiften usw. ist aber der tatsächliche Geruchszustand durchaus recht kompliziert und die starre Anordnung überfordert. So treten zu hohe Konzentrationen auf, aber auch zu niedrige, versteckte oder die Messanordnung zerstörende Gasanteile. Dann versagt die passive starre Messanordnung.In practice, in the odor detection of diseases, food qualities, environmental toxins, etc., but the actual smell is quite quite complicated and the rigid arrangement overwhelmed. Too high concentrations occur, but also too low, hidden or the measuring arrangement destructive gas components. Then the passive rigid measuring arrangement fails.
Aufgabe ist es deshalb, die Geruchsmesstechnik und Geruchsklassifizierung auf ein solches Niveau anzuheben, dass die genannten Schwierigkeiten egalisiert werden.The task is therefore to raise the odor measurement and odor classification to such a level that the stated difficulties are leveled out.
Die Grenze der bisherigen Technik wird nun dadurch durchbrochen, dass eine neue Detektionseinheit aus Probenbeeinflussung, steuerbarem Gassensor, elektronischer Steuer- und Regeleinheit und einem lernfähigen Computer gebildet wird. Damit wird die bisherige starre passive Anordnung in eine aktive überführt. Sie adaptiert an die vorliegende Gaszusammensetzung des Geruchs, passt sich an die Höhe der Konzentrationen an, macht Teile des Geruchs oder Empfindlichkeitsänderungen erstmalig über eine Probenbeeinflussung messbar und setzt neue Erkennungsalgorithmen im Rechnerprogramm ein.The limit of the prior art is now broken by the fact that a new detection unit of sample control, controllable gas sensor, electronic control and regulation unit and a learning computer is formed. This converts the previous rigid passive arrangement into an active one. It adapts to the existing gas composition of the odor, adapts to the level of the concentrations, makes parts of the odor or sensitivity changes measurable for the first time via a sample influence and uses new recognition algorithms in the computer program.
Die neue Lösung soll nachfolgend erläutert werden.The new solution will be explained below.
Unter Probenbeeinflussung wird die Temperaturänderung des Geruchs beispielsweise wie bei der fraktionierten Destillation, der Austreibung von einzelnen Gasen oder ihrer Immobilisierung sowie das Verbringen in eine gasförmige Phase bei Flüssigkeiten, Festkörpern oder biologischen Körpern oder auch nur das Verbringen in eine der Temperatur des Gassensors angepassten Größe verstanden. Neben der Temperatur sind zur Beeinflussung der Probe auch ein Versprayen, chemische Aufbereitungsreaktionen oder biologische Wachstums- und Sterbevorgänge wie auch optische und sonstige Energieeinträge einsetzbar.Under sample influence, the temperature change of the odor is understood as in the fractional distillation, the expulsion of individual gases or their immobilization as well as the introduction into a gaseous phase in liquids, solids or biological bodies, or even the introduction into a size adapted to the temperature of the gas sensor , In addition to the temperature, spraying, chemical treatment reactions or biological growth and dying processes as well as optical and other energy inputs can also be used to influence the sample.
Unter steuerbarem Gassensor wird verstanden, dass die gassensitive Anordnung durch einen Aktor in ihren Parametern steuerbar gemacht wird. Das sind die Steuerbarkeit der Empfindlichkeit, das Herausgreifen von Teilen, eine Zoom-Funktion durch Selektivitäts- und Wobbelverfahren, das Nutzen parametrischer Effekte oder Selbstheilung mittels Regenerierung aus Depots oder Messunterbrechungen.Under controllable gas sensor is understood that the gas-sensitive arrangement is made controllable by an actuator in their parameters. These include the controllability of sensitivity, the picking out of parts, a zoom function through selectivity and sweep methods, the use of parametric effects or self-healing by means of regeneration from depots or measurement interruptions.
Unter elektronischer Steuer- und Regelungseinheit wird die durch eine Schaltungstechnik oder Computersoftware einstellbare Steuerung oder Regelung der oben genannten Elemente der neuen Detektionseinheit Probenbeeinflussung und steuerbarer Gassensor verstanden.Electronic control and regulation unit is understood to mean the control or regulation of the above-mentioned elements of the new detection unit sample control and controllable gas sensor that can be set by circuit technology or computer software.
Unter lernfähigem Computer werden Computerprogramme verstanden, die die o. g. Adaption bewerkstelligen. Diese Software kommt aus der Theorie der Objekterkennung, Neuronalen Netzen, der Regelungstechnik Optimierungsrechnung usw.Under adaptive computer computer programs are understood, the o. G. Accomplish adaptation. This software comes from the theory of object recognition, neural networks, control engineering optimization calculation, etc.
