Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren und eine Einrichtung zur autonomen Energieversorgung von Mess- und Sendeeinrichtungen in Geräten, Maschinen, wie beispielsweise Motoren oder in technischen Anlagen.The The invention relates to a method and a device for autonomous power supply of measuring and transmission equipment in Devices, machines, such as motors or in technical equipment.
In einer Vielzahl von Anwendungsfällen besteht die Anforderung, Messwerte in oder an Geräten, Maschinen oder technischen Anlagen zu erfassen, ohne dabei Zugriff auf die Energieversorgung der Anlage zu haben. Ein typisches Beispiel hierfür ist die Überwachung von Motorlagern mittels Beschleunigungssensoren und Auswertung eines erfassten Frequenzspektrums zur Früherkennung von Lagerausfällen. So ermittelte Messdaten werden mittels einer Sendeeinrichtung zu einer Empfangseinrichtung außerhalb des Motors übertragen.In a variety of applications, there is the requirement Measured values in or on devices, machines or technical Capture equipment without losing access to the energy supply of the To have facility. A typical example of this is monitoring of engine bearings by means of acceleration sensors and evaluation of a recorded frequency spectrum for the early detection of bearing failures. Measurement data determined in this way are transmitted by means of a transmitting device a receiving device outside the engine transmitted.
Eine bekannte Lösung zur Schaffung einer Energieversorgung für eine solche Mess- und Sendeeinrichtung besteht darin, die Mess- und Sendeeinrichtung mit Energie aus einer Batterie, z. B. einer Lithium-Batterie zu versorgen. Nachteilig ist allerdings die begrenzte Lebensdauer derartiger Batterien, die eine Überwachung und den rechtzeitigen Austausch verbrauchter Batterien erforderlich macht. Die dazu nötigen Maßnahmen sind zeit- und kostenaufwändig. Außerdem wird die Umwelt durch die bei derartigen Batterien eingesetzten Materialien belastet.A known solution for creating a power supply for Such a measuring and transmitting device consists in measuring the measuring and transmitting means with energy from a battery, for. B. a lithium battery to supply. However, the disadvantage is the limited life Such batteries, monitoring and timely replacement consumed batteries required. The necessary Measures are time-consuming and costly. Furthermore the environment is used by those used in such batteries Materials loaded.
Bei einer alternativen bekannten Lösung werden Motorvibrationen ausgenutzt, um elektrische Energie zu generieren. Grundsätzlicher Nachteil dieser Lösung ist jedoch, dass bekannte Geräte zur Nutzung von Motorvibrationen nur in einem schmalen Frequenzbereich effektiv arbeiten, z. B. im Bereich von 49,5 bis 50,5 Hz. Zunehmend werden aber drehzahlgesteuerte Motoren eingesetzt, weil beispielsweise ein lebensdauererhöhender Sanftanlauf und/oder eine variable Drehzahl gefordert sind, wobei Geräte zur Nutzung von Motorvibrationen nicht oder nur ineffektiv eingesetzt werden können. Außerdem haben solche Geräte einen relativ hohen Preis.at An alternative known solution is engine vibration exploited to generate electrical energy. fundamental Disadvantage of this solution, however, is that known devices for the use of engine vibrations only in a narrow frequency range work effectively, eg. In the range of 49.5 to 50.5 Hz. Increasingly But speed-controlled motors are used because, for example a life-enhancing soft start and / or a variable Speed are required, with devices for the use of engine vibrations can not be used or only ineffective. Furthermore Such devices have a relatively high price.

In einer – noch nicht optimierten – Versuchsanordnung zur Erprobung der vorgeschlagenen Lösung wurde ein modifizierter Mikrofan mit einer Luftdurchtrittsfläche von 2,5 × 2,5 cm2 mittels Permanentmagneten an der Kühllufteintrittsseite eines drehzahlgeregelten 37-kW-Pumpenmotors montiert, dessen Kühllufteintrittsgitter eine Fläche von 400 cm2 hat, so dass das Verhältnis der beiden Flächen 1:64 betrug, also für die Kühlluftversorgung des Motors völlig unkritisch war. Mit dieser Anordnung wurde abhängig von der Motordrehzahl eine Leistung von bis zu 4,5 mW generiert. Die maximale Motordrehzahl betrug dabei 3000 U/min.In a - not yet optimized - experimental design for testing the proposed solution, a modified microfan was installed with an air passage area of 2.5 × 2.5 cm 2 by means of permanent magnets on the cooling air inlet side of a speed-controlled 37 kW pump motor, the cooling air inlet grille an area of 400 cm 2 , so that the ratio of the two surfaces was 1:64, that was completely uncritical for the cooling air supply of the engine. With this arrangement, a power of up to 4.5 mW was generated depending on the engine speed. The maximum engine speed was 3000 U / min.
Für Anwendungen, bei denen – z. B. wegen pulsförmiger Last der Sendeeinrichtung – eine bestimmte Leistung möglichst gleichbleibend zur Verfügung stehen soll, kann ein Stützspeicher angeordnet werden. Das kann z. B. mittels eines elektrischen Kondensators hoher Kapazität erfolgen, der langlebig und wartungsfrei ist.For Applications in which -.

Zur Durchführung eines Versuchs wurde ein Konverter auf eine etwa 50 mm hohe Kühlrippe des oben angegebenen 37-kW-Motors montiert. Nach erreichen der Betriebstemperatur des Motors wurde eine elektrische Leistung von 32 mW generiert.to Performing a trial was a converter to one about 50 mm high cooling fin of the above 37 kW motor assembled. After reaching the operating temperature of the engine was a electrical power of 32 mW generated.
Die erfindungsgemäßen Anordnungen sind auch in Schaltzellen, Transformatorstationen oder sonstigen Anlagen einsetzbar, wobei ein zusätzlicher Vorteil darin besteht, dass die Einsatzstellen auf hohem elektrischen Potential liegen können, sofern dort ein ausreichender Kühlluftstrom vorhanden ist.The arrangements according to the invention are also in switch cells, Transformer stations or other systems used, wherein An additional advantage is that the deployment sites can be at high electrical potential, provided There is sufficient cooling air flow there.
