Abstract
Description
Die Erfindung betrifft ein Pumpenaggregat mit den im Oberbegriff des Anspruches 1 angegebenen Merkmalen.The invention relates to a pump unit with the features specified in the preamble of claim 1.
Pumpenaggregate der eingangs erwähnten Art sind in zahlreichen Ausführungen bekannt, sie werden heutzutage beispielsweise als Heizungsumwälzpumpen eingesetzt. Die Miniaturisierung im elektronischen Bereich hat es ermöglicht, daß heutzutage elektronische Drehzahlsteller im Pumpenaggregat integriert sind, die das Betreiben der Pumpe in Kennfeldern ermöglichen. Hierzu ist dem Drehzahlsteller eine elektronische Regelung zugeordnet. Über eine im Pumpenaggregat integrierte elektronische Steuerung können über einen am Pumpengehäuse von außen zugänglichen Schalter die gewünschten Betriebspunkte des Pumpenaggregates voreingestellt werden. Es hat sich bewährt, verschiedene Regelgrößen oder auch Regelkennlinien vorzugeben, die jeweils einen bedarfsgerechten Pumpenbetrieb ermöglichen und die durch entsprechende Schalter an der Außenseite des Pumpenaggregates vorwählbar sind. Je nach Schalterstellung kann das Pumpenaggregat also mit unterschiedlichen Regelmodi betrieben werden, je nach Anforderungsprofil.Pump units of the type mentioned at the outset are known in numerous designs; today, they are used, for example, as heating circulation pumps. The miniaturization in the electronic field has made it possible for electronic speed controllers to be integrated in the pump unit, which enable the pump to be operated in characteristic maps. For this purpose, electronic control is assigned to the speed controller. An electronic control integrated in the pump unit can be used to preset the desired operating points of the pump unit via a switch that is accessible from the outside of the pump housing. It has proven useful to specify various control variables or control characteristics, each of which enables pump operation to be carried out as required and which can be preselected by means of appropriate switches on the outside of the pump unit. Depending on the switch position, the pump set can be operated with different control modes, depending on the requirement profile.
Im Zuge der immer komplexer werdenden Regelungssysteme in Heizungsanlagen, die oft mehrere derartiger Pumpenaggregate aufweisen, ist eine Veränderung der Betriebsparameter der Pumpe häufig nicht nur einmalig nach dem Einbau, sondern auch während des Betriebs erforderlich. Insbesondere in großen Heizungsanlagen, die auf engem Raum installiert werden müssen, stellt sich zudem das Problem der Zugänglichkeit zu den Pumpenaggregaten. Es muß also beim Einbau stets darauf geachtet werden, daß eine Bedienperson das Pumpenaggregat erreichen kann, um die entsprechenden Einstellungen daran vornehmen zu können. Andernfalls sind aufwendige Verkabelungen und externe Schalter erforderlich, was man verständlicherweise zu vermeiden versucht. Andererseits bedingt die Zugänglichkeit der Pumpen im Betriebsstörfall häufig, daß zur vermeintlichen Behebung eines Schadens die am Aggregat vorhandenen Schalter willkürlich verstellt werden, um durch Probieren die Fehler aufzufinden. Das System ist dann verstimmt und muß von dem Fachmann in aufwendiger Arbeit neu eingestellt werden, indem die einzelnen Pumpenaggregate wieder auf die vorgesehenen Werte eingestellt werden.In the course of the increasingly complex control systems in heating systems, which often have several pump units of this type, it is often necessary to change the operating parameters of the pump not only once after installation, but also during operation. In large heating systems in particular, which have to be installed in a small space, there is also the problem of accessibility to the pump units. It must therefore always be ensured during installation that an operator can reach the pump set in order to be able to make the appropriate settings on it. Otherwise, complex cabling and external switches are required, which understandably tries to avoid. On the other hand, the accessibility of the pumps in the event of a malfunction often means that the switches present on the unit are to be arbitrarily adjusted in order to alleviate damage in order to find the errors by trying. The system is then out of tune and has to be readjusted by the skilled worker in complex work by resetting the individual pump units to the intended values.
Ausgehend von dem einleitend genannten Stand der Technik liegt der vorliegenden Erfindung die Aufgabe zugrunde, ein gattungsgemäßes Pumpenaggregat mit konstruktiv einfachen, in der Herstellung günstigen und im Betrieb zuverlässig arbeitenden Mitteln so auszubilden, daß die vorerwähnten Nachteile nach Möglichkeit oder zumindest weitgehend vermieden werden können.Based on the prior art mentioned in the introduction, the object of the present invention is to design a generic pump unit with structurally simple means which are inexpensive to produce and operate reliably in such a way that the aforementioned disadvantages can be avoided as far as possible or at least largely.
Diese Aufgabe wird bei einem gattungsgemäßen Pumpenaggregat durch die im kennzeichnenden Teil des Anspruches 1 angegebenen Merkmale gelöst. Die Erfindung sieht also eine drahtlose mobile Fernsteuerung für das Pumpenaggregat vor, mit dem mindestens eine gewünschte Regelgröße eingestellt werden kann. Dies bringt in der Praxis erhebliche Vorteile mit sich.This object is achieved in a generic pump unit by the features specified in the characterizing part of claim 1. The invention therefore provides a wireless mobile remote control for the pump unit, with which at least a desired control variable can be set. In practice, this has considerable advantages.
So kann das Aggregat auch an schwer zugänglichen Stellen angeordnet werden, ohne die Bedienbarkeit zu gefährden. Es kann auf kostenaufwendige und störanfällige Verdrahtungen verzichtet werden. Bei entsprechender Handhabung des Senders können Fehlbedienungen weitgehend dadurch ausgeschlossen werden, daß der Sender nur dem Fachmann zugänglich ist und im übrigen unter Verschluß gehalten wird. Bei entsprechender Auslegung der Übertragungsart (Funk) ist es sogar möglich, unterschiedliche Pumpenaggregate von einer zentralen Stelle aus zu steuern bzw. zu bedienen, ohne daß eine zusätzliche Verdrahtung erforderlich ist.In this way, the unit can also be arranged in places that are difficult to access without endangering operability. Costly and fault-prone wiring is not necessary. With appropriate handling of the transmitter, incorrect operation can largely be ruled out by the transmitter being accessible only to the specialist and being kept under lock and key. With appropriate design of the transmission type (radio), it is even possible to control or operate different pump sets from a central location without additional wiring being required.
Aus DE 38 28 207 A1 ist es zwar bekannt, dem Pumpenaggregat einen Anschlußbaustein zur Aufnahme einer Meßvorrichtung für die elektrischen bzw. hydraulischen Betriebsgrößen von Motor bzw. Pumpen zuzuordnen und auf diesem Anschlußbaustein von außen lösbar einen weiteren, eine Registriervorrichtung zur Speicherung und Anzeige von Betriebsgrößen lösbar anzubringen und eine drahtlose Übertragung von Daten zwischen Anschlußbaustein und dem weiteren lösbaren Baustein vorzusehen, doch dient hier die drahtlose Übertragung lediglich der elektrischen Sicherheit, im übrigen weist dieses Pumpenaggregat all die Nachteile auf, die eingangs anhand des Standes der Technik erläutert worden sind, von dem die vorliegende Erfindung ausgeht.From DE 38 28 207 A1 it is known to assign a connection module for receiving a measuring device for the electrical or hydraulic operating variables of the motor or pumps to the pump unit and releasably on this connecting module from the outside a further registration device for storing and displaying operating variables to be releasably attached and to provide a wireless transmission of data between the connection module and the further releasable module, but here the wireless transmission only serves for electrical safety, otherwise this pump unit has all the disadvantages that were initially explained with reference to the prior art, of which the present invention is based on.
Besonders vorteilhaft ist es, wenn das Pumpenaggregat nicht nur einen Empfänger aufweist, sondern auch einen Sender, da dann nicht nur Stellgrößen zum Aggregat übermittelt, sondern auch Betriebsdaten des Aggregates drahtlos an einen externen Empfänger übermittelt werden können. Es versteht sich, daß es zweckmäßig ist, den externen Sender und den externen Empfänger in einem gemeinsamen Gerät zu integrieren, mit dem das Pumpenaggregat bedient und überprüft werden kann. Auf diese Weise wird eine externe Bedien- und Kontrolleinheit des Pumpenaggregates gebildet.It is particularly advantageous if the pump unit not only has a receiver, but also a transmitter, since then not only transmits manipulated variables to the unit, but also wirelessly operating data of the unit to an external receiver can be transmitted. It goes without saying that it is expedient to integrate the external transmitter and the external receiver in a common device with which the pump unit can be operated and checked. In this way, an external operating and control unit of the pump unit is formed.
Eine solche Bedien- und Kontrolleinheit weist zweckmäßigerweise ein Display zur Anzeige der übermittelten Betriebsdaten auf, so daß der Bediener mit einem Blick das entsprechende Pumpenaggregat überprüfen kann und auch sofort Rückwirkungen über seine durchgeführten Einstellungsänderungen erhält. Derartige Displays sind bei modernen Pumpenaggregaten auch schon am Aggregat selbst zu finden. Die gemäß der Erfindung vorgesehene mobile Baueinheit (Bedienteil) als Bedien- und Kontrolleinheit hat dann den Vorteil, daß ein entsprechendes Display an der Pumpe entfallen kann.Such an operating and control unit expediently has a display for displaying the transmitted operating data, so that the operator can check the corresponding pump unit at a glance and also immediately receives repercussions about the changes made to his settings. Such displays can also be found on modern pump units on the unit itself. The mobile structural unit (control unit) provided according to the invention as an operating and control unit then has the advantage that a corresponding display on the pump can be omitted.
Wird die Bedien- und Kontrolleinheit für mehrere Pumpen genutzt, was technisch mit Hilfe einer geeigneten Identifizierung ohne weiteres möglich ist, so ergeben sich hierdurch ganz erhebliche Einsparungen bei den Baukosten, wobei die vereinfachte Montage durch quasi beliebige Anordnung des Aggregates im Leitungsweg noch gar nicht berücksichtigt ist.If the operating and control unit is used for several pumps, which is technically possible with the help of a suitable identification, this results in very considerable savings in construction costs, whereby the simplified assembly due to virtually any arrangement of the unit in the pipeline does not even take into account is.
Bevorzugt kann die Bedien- und Kontrolleinheit auch eine Druck- oder Speichereinheit zum Aufzeichnen von Betriebsdaten sowie eine Schnittstelle zum Anschluß eines Druckers oder anderen Datenspeichers aufweisen. Eine derartige Einrichtung ist insbesondere dann zweckmäßig, wenn über längere Zeit Daten zuverlässig aufgezeichnet werden sollen, wie dies beispielsweise bei der Suche von nur sporadisch auftretenden Störungen im System erforderlich ist. Es ist beispielsweise denkbar, daß Bedien- und Kontrolleinheiten gemäß der Erfindung mit unterschiedlichen Zugangsberechtigungen ausgegeben werden, so daß der Betreiber einer Anlage beispielsweise an seiner Bedien- und Kontrolleinheit nur die Einstellungen durchführen kann, die vorher durch den Fachmann freigegeben worden sind, während mit der Bedien- und Kontrolleinheit des Wartungspersonales sämtliche Einstellungen durchgeführt werden können. So kann es beispielsweise für den Betreiber ausreichend sein, als Betriebsdaten nur den jeweiligen Betriebszustand (an oder aus) wählen zu können sowie die Betriebsstundendauer zu kennen, wahrend für das Wartungspersonal auch andere pumpenspezifische Daten angezeigt werden und einstellbar sein sollen.The operating and control unit can preferably also have a printing or storage unit for recording operating data and an interface for connecting a printer or other data memory. Such a device is particularly useful if data is to be recorded reliably over a long period of time, as is required, for example, when searching for faults in the system which only occur sporadically is. It is conceivable, for example, that operating and control units according to the invention are issued with different access authorizations, so that the operator of a system can, for example, only make the settings on his operating and control unit that have previously been released by the expert, while the Operating and control unit of the maintenance personnel all settings can be carried out. For example, it may be sufficient for the operator to be able to select only the respective operating status (on or off) as operating data and to know the operating hours, while other pump-specific data should also be displayed and should be adjustable for the maintenance personnel.
Für den Bereich kurzer Entfernungen ist es zweckmäßig, die Kommunikation zwischen Sender und Empfänger durch Lichtsignale, vorzugsweise im Infrarotbereich erfolgen zu lassen. Hier ist eine zuverlässige Datenübertragung bei vergleichsweise geringem Bauaufwand möglich. Wird hingegen an eine Art drahtlose Fernabfrage gedacht, so empfiehlt sich eine Datenübertragung über Funk. So können die jeweils benötigten Betriebsdaten auch über größere Entfernungen und aus geschlossenen Räumen heraus übermittelt und gegebenenfalls durch entsprechende Bedienung geändert werden.For the range of short distances, it is expedient to allow the communication between transmitter and receiver to take place by means of light signals, preferably in the infrared range. Reliable data transmission with comparatively low construction costs is possible here. If, on the other hand, a kind of wireless remote inquiry is being considered, data transmission via radio is recommended. In this way, the required operating data can also be transmitted over longer distances and from closed rooms and, if necessary, changed by appropriate operation.

In Fig. 1 ist ein elektromotorisch angetriebenes Pumpenaggregat 1 dargestellt, wie es beispielsweise in Heizungsanlagen als Umwälzpumpe einsetzbar ist. Die Regelelektronik sowie der Drehzahlsteller in Form eines Frequenzumrichters - diese Bauteile sind üblicherweise im Klemmenkasten des Aggregates angeordnet - sind mit 2 bezeichnet. Die Bezugsziffer 3 kennzeichnet die der Regelelektronik vorgeschaltete Sende- und Empfangselektronik, soweit sie aggregatseitig angeordnet ist. Die mit der Sende- und Empfangselektronik 3 des Pumpenaggregates 1 kommunizierende Sende- und Empfangselektronik ist innerhalb einer mobilen Baueinheit 4 (Bedienteil) in Form einer Bedien- und Kontrolleinheit angeordnet. Die Pfeile 5 und 6 symbolisieren den drahtlosen Datenfluß von der Bedien- und Kontrolleinheit 4 zum Pumpenaggregat 1 und umgekehrt.In Fig. 1, an electric motor-driven pump unit 1 is shown, as it can be used for example in heating systems as a circulation pump.

Das pumpenseitige Sende- und Empfangsteil 3 weist einen Infrarotsender 7 sowie einen Infrarotempfänger 8 auf, denen im Bedienteil 4 jeweils ein Infrarotsender 9 sowie ein Infrarotempfänger 10 zugeordnet sind. Das Bedienteil 4 weist ein numerisches Eingabefeld 11 auf, über das Zahlenkombinationen eingebbar sind, denen entsprechende Steuerbefehle zugeordnet werden, und zwar über den in der Sende- und Empfangselektronik 3 mit 12 bezeichnetem Wandlerbaustein, der das Ausgangssignal des IR-Empfängers 8 in ein für die Regelelektronik 2 verständliches Signal umwandelt. Die Signalverbindung zwischen der Sende- und Empfangselektronik 3 und der Regelelektronik 2 ist mit 13 gekennzeichnet. Auf diese Weise können durch entsprechende Zahleneingaben über das Eingabefeld 11 mittels des Infrarotsenders 9 Signale an den Infrarotempfänger 8 gesendet werden, die über den Wandlerbaustein 12 dechiffriert werden bzw. in ein Signal umgesetzt werden, mit dem in der Regelelektronik 2 unmittelbar Kennlinien angewählt werden können.The pump-side transmitting and receiving

Im vorliegenden Ausführungsbeispiel werden anhand elektrischer Daten des Motors, beispielsweise der Drehzahl sowie der Leistung entsprechende Daten der Pumpe ermittelt und zur Anzeige gebracht.Via the
Alternativ oder zusätzlich kann im Bedienteil 4 auch ein Drucker vorgesehen sein, mit dem ein Datenprotokoll ausdruckbar ist.
