Stromversorgungen werden üblicherweise als Standalone-Vor- richtungen betrieben. Sie sind in der Regel mit einem ein- fachen Meldekontakt ausgestattet. Damit kann angezeigt werden, ob der Zustand der Stromversorgung derzeit ungestört oder gestört ist.Power supplies are usually operated as standalone devices. They are usually equipped with a simple signaling contact. It can be used to indicate whether the state of the power supply is currently undisturbed or faulty.
Stromversorgungen setzen typischerweise ein eingangsseitiges hohes Spannungsniveau, beispielsweise eine 230V~Wechselspan- nung oder eine 400V- echselspannung, auf ein niedriges Spannungsniveau, beispielsweise eine Gleichspannung von 24V, um. Dadurch können Verbraucher wie Sensoren, elektronische Steuerungen, Ventile und Pumpen mit einer geeigneten Spannung be- trieben werden, ohne dass für jeden einzelnen Verbraucher eine .eigene Stromversorgung notwendig ist . Derartige Stromversorgungen werden beispielsweise in der Fertigungs- und Automatisierungstechnik in großem umfang eingesetzt.Power supplies typically convert a high voltage level on the input side, for example a 230 V AC voltage or a 400 V AC voltage, to a low voltage level, for example a 24 V DC voltage. This enables consumers such as sensors, electronic controls, valves and pumps to be operated with a suitable voltage without the need for their own power supply for each individual consumer. Such power supplies are widely used, for example, in manufacturing and automation technology.

Im Falle einer unzulässigenPower supply and a power supply equipped with a diagnostic unit are described. The diagnostic unit monitors the power supply on the output side for an impermissible deviation of at least one parameter to be monitored from a comparison value. In the case of an impermissible
Abweichung von dem Vergleichswert erfasst die Diagnoseeinheit Messwerte auf der Eingangsseite der Stromversorgung im zeitlichen Umfeld der unzulässigen Abweichung in einem Zeitfenster. Die Diagnoseeinheit legt dann die zugehörigen Messwerte in einem Speicher ab. Dadurch wird erreicht, dass die von einer netzseitigen Störung verursachte Abweichung eines zu überwachenden Parameters, beispielsweise eine ünterschreitung der Ausgangsspannung, zweifelsfrei dokumentiert werden kann. Auf diese Weise kann einem Betreiber der Stromversorgung nachgewiesen werden, dass nicht die Stromversorgung, sondern das übergeordnete Stromnetz nicht den spezifizierten Anforde- rungen zum Betrieb von Stromversorgungen genügt. Eingangsund ausgangsseitige Netzfehler sowie stromversorgungsseitige Gerätefehler können problemlos und zeitnah mit geringem Aufwand erfasst, abgefragt und analysiert werden. In einer Ausführungsform weist die Diagnoseeinheit eine Kommunikations- Schnittstelle zum Auslesen des Speichers aus. Über dieseDeviation from the comparison value, the diagnostic unit records measured values on the input side of the power supply in the time environment of the impermissible deviation in a time window. The diagnostic unit then stores the associated measured values in a memory. It is thereby achieved that the deviation of a parameter to be monitored caused by a network-side fault, for example a shortfall the output voltage, can be documented beyond doubt. In this way, an operator of the power supply can be shown that not the power supply, but the higher-level power grid does not meet the specified requirements for operating power supplies.

In one embodiment, the diagnostic unit has a communication interface for reading out the memory. About these

Beispielsweise kann es sich bei den Verbindungen zwischen den Stromversorgungskomponenten und dem Konzentrator um einen unter Verwendung von Kabeln realisierten Bus handeln, während der Konzen- trator mit der Analyse- und Steuereinheit über einen drahtlosen Kommunikationskanal verbunden ist, beispielsweise eine Funkübertragungsstrecke.Power supply all internal parameters of the power supply can be evaluated, logged, set and controlled.

For example, the connections between the power supply components and the concentrator can be a bus implemented using cables, while the concentrator is connected to the analysis and control unit via a wireless communication channel, for example a radio transmission link.

These memories 2a, 3a, 4a, 5a and 6a are each implemented in the form of a ring memory and store data that describe the states of the respective components for the duration of a predetermined time window.
Diese Daten werden dann zyklisch, nach Ablauf vorgegebener Zeitintervalle oder bei Abruf durch eine externe Analyse- und Steuereinheit 7 an einer Schnittstelle S der jeweiligen Komponente ausgegeben und einem Bus 10 zur Verfügung gestellt. Bei diesem Bus kann es sich um das Ethernet, um einen Profibus, einen IEC-Bus oder einen CAN-Bus handeln. Alternativ dazu können die Schnittstellen S auch Schnittstellen zum Internet, GSM-Schnittstellen, UMTS-Schnittstellen, USB-Schnitt- stellen, Funkschnittstellen oder Infrarot-Schnittstellen sein.These data are then output cyclically, at the end of predetermined time intervals or when called up by an external analysis and control unit 7 at an interface S of the respective component and made available to a bus 10. This bus can be Ethernet, a Profibus, an IEC bus or a CAN bus. Alternatively, the interfaces S can also be interfaces to the Internet, GSM interfaces, UMTS interfaces, USB interfaces, radio interfaces or infrared interfaces.
Bei der externen Analyse- und Steuereinheit 7 handelt es sich vorzugsweise um einen Personalcomputer. Dieser weist eine Tastatur 7a, einen Prozessor 7b, einen Speicher 7c und einThe external analysis and control unit 7 is preferably a personal computer. This has a keyboard 7a, a processor 7b, a memory 7c and a
Display 7d auf. Die Analyse- und Steuereinheit 7 empfängt und analysiert die über den Bus 10 übertragenen Daten der einzelnen Komponenten 2, 3, 4, 5 und 6 der Stromversorgung 1. Die Analyse- und Steuereinheit 7 ist deshalb stets über alle in- ternen Parameter der Stromversorgung 1 informiert und folglich dazu in der Lage, ein Stromversorgungsmanagement durchzuführen. Dabei gibt sie Befehls- bzw. Steuersignale oder Steuerprogramme aus, die über den Bus 10 an die jeweilige Komponente 2, 3, 4, 5 oder 6 der Stromversorgung 1 übertragen werden und die Arbeitsweise der jeweiligen Komponente beeinflussen. Weiterhin sorgt die Prozessoreinheit 7b dafür, dass den internen Parametern der Stromversorgung 1 entsprechende Daten in einem Speicherbereich des Speichers 7c dauerhaft abgespeichert bzw. protokolliert werden, so dass sie bei Bedarf für eine spätere Auswertung zur Verfügung stehen. Ferner sorgt die Prozessoreinheit 7b dafür, dass im Sinne eines Stromversorgungsmonitorings auf dem Display 7d in alphanumerischer und/oder grafischer Form Diagramme oder Tabellen dargestellt werden, die dem Servicepersonal der jeweiligen An- l ge Informationen über die Zustände der einzelnen Stromversorgungskomponenten geben.Display 7d. The analysis and control unit 7 receives and analyzes the data of the individual components 2, 3, 4, 5 and 6 of the power supply 1 transmitted via the bus 10. The analysis and control unit 7 is therefore always aware of all internal parameters of the power supply 1 informed and consequently able to perform power supply management. It issues command or control signals or control programs which are transmitted via bus 10 to the respective component 2, 3, 4, 5 or 6 of power supply 1 and which influence the mode of operation of the respective component. Furthermore, the processor unit 7b ensures that data corresponding to the internal parameters of the power supply 1 are permanently stored or logged in a memory area of the memory 7c, so that they are available for later evaluation if required. Furthermore, the processor unit 7b ensures that, in the sense of a power supply monitoring, the display 7d shows, in alphanumeric and / or graphic form, diagrams or tables which give the service personnel of the respective system information about the status of the individual power supply components.

Die Figur 2 zeigt eine Blockdarstellung eines zweiten Ausführungsbeispiels für eine Vorrichtung zur Stromversorgung. Die in der Figur 2 dargestellte Vorrichtung unterscheidet sich von der in der Figur 1 dargestellten Vorrichtung lediglich dadurch, dass zwischen den Stromversorgungskomponenten 2, 3, 4, 5, 6 der Stromversorgung 1 und der Analyse- und Steuereinheit 7 ein Konzentrator 8 angeordnet ist. Dieser Konzentrator 8 ist über einen Bus 10 mit den genannten Stromversorgungskomponenten 2, 3, 4, 5, 6 verbunden. Weiterhin ist der Kon- zentrator 8 über einen Kommunikationskanal 9 mit der externen Analyse- und Steuereinheit 7 verbunden.FIG. 2 shows a block diagram of a second exemplary embodiment for a device for power supply. The device shown in FIG. 2 differs from the device shown in FIG. 1 only in that a concentrator 8 is arranged between the power supply components 2, 3, 4, 5, 6 of the power supply 1 and the analysis and control unit 7. This concentrator 8 is connected via a bus 10 to the aforementioned power supply components 2, 3, 4, 5, 6. Furthermore, the concentrator 8 is connected to the external analysis and control unit 7 via a communication channel 9.
Der Vorteil dieses zweiten Ausführungsbeispiels besteht insbesondere darin, dass die zwischen den Stromversorgungskompo- nenten und dem Konzentrator 8 vorgesehenen Verbindungen andersartig als die zwischen dem Konzentrator 8 und der Analyse- und Steuereinheit 7 vorgesehene Verbindung 9 realisiert sein können. Beispielsweise handelt es sich bei den zwischen den Stromversorgungskomponenten 2, 3, 4, 5, 6 und dem Konzentrator 8 vorgesehenen Verbindungen um verdrahtete Busleitungen, während der Ko munikationskanal 9 zwischen dem Konzentrator 8 und der Analyse- und Steuereinheit 7 beispielsweise eine Funkübertragungsstrecke oder das Internet ist. Dies ermöglicht es, die Analyse- und Steuereinheit 7 in großer Entfernung vom Konzentrator 8 und damit auch in großer Entfernung von der Stromversorgung 1 vorzusehen.The advantage of this second exemplary embodiment is in particular that the connections provided between the power supply components and the concentrator 8 are implemented differently than the connections 9 provided between the concentrator 8 and the analysis and control unit 7 could be. For example, the connections provided between the power supply components 2, 3, 4, 5, 6 and the concentrator 8 are wired bus lines, while the communication channel 9 between the concentrator 8 and the analysis and control unit 7 is, for example, a radio transmission link or the Internet is. This makes it possible to provide the analysis and control unit 7 at a great distance from the concentrator 8 and thus also at a great distance from the power supply 1.
Eine Vorrichtung zur Stromversorgung gemäß der vorliegenden Erfindung weist demnach mehrere Stromversorgungskomponenten auf, die jeweils eine Kommunikationsschnittstelle haben. Sie sind über diese Kommunikationsschnittstelle direkt oder über einen Konzentrator mit einer externen Analyse- und Steuereinheit verbunden. Diese überwacht im Sinne eines Online-Betriebes alle Parameter der Stromversorgung und verändert beispielsweise bei Erkennung eines Fehlerfalles die Betriebsart der Stromversorgung. Beispielsweise steuert sie einen Redun- danzbetrieb, einen Notbetrieb oder eine Lastverteilung. Die im Rahmen des Online-Betriebes gemeldeten Parameter der einzelnen Komponenten der Stromversorgung werden in einem Speicher der Analyse- und Steuereinheit protokolliert und stehen bei Bedarf für eine spätere detaillierte Analyse der Strom- Versorgung zur Verfügung. Ein Stromversorgungsmanagement gemäß der Erfindung erhöht die Verfügbarkeit und die Zuverlässigkeit des gesamten Stromversorgungssystems und damit auch des Automatisierungs- oder Fertigungssystems, in welchem das Stromversorgungssystem eingesetzt ist.A device for power supply according to the present invention accordingly has a plurality of power supply components, each of which has a communication interface. They are connected to an external analysis and control unit directly via this communication interface or via a concentrator. In the sense of online operation, this monitors all parameters of the power supply and changes the operating mode of the power supply, for example, when an error is detected. For example, it controls redundancy, emergency operation or load distribution. The parameters of the individual components of the power supply that are reported as part of online operation are logged in a memory of the analysis and control unit and are available for later detailed analysis of the power supply if required. A power supply management system according to the invention increases the availability and the reliability of the entire power supply system and thus also of the automation or manufacturing system in which the power supply system is used.
Alternativ zu den anhand der Figuren beschriebenen Ausführungsbeispielen kann es sich bei der Analyse- und Steuereinheit 7 anstelle eines Personalcomputers auch um ein Programmiergerät, .um eine speicherprogrammierbare Steuerung oder um eine Fernsteuerungseinheit handeln. Eine Vorrichtung gemäß der Erfindung ermöglicht in vorteilhafter Weise der Analyse- und Steuereinheit 7 Steuersignale zu generieren, aufgrund derer die Arbeitsweise der Stromversorgung 1 umgeschaltet oder umprogrammiert wird, beispiels- weise von einer Stromversorgungsbetriebsart in eine Ladegerätbetriebsart. Diese Umschaltung kann rein softwaremäßig vorgenommen werden oder unter Verwendung eines in der jeweiligen Stromversorgungskomponente angeordneten Schalters, dessen Schaltbetrieb von der Analyse- und Steuereinheit 7 ge- steuert wird. Ein derartiger Schalter ist in den Figuren 1 und 2 gestrichelt angedeutet und mit dem Bezugszeichen 2b versehen. As an alternative to the exemplary embodiments described with reference to the figures, the analysis and control unit 7 can also be a programming device, a programmable logic controller or a remote control unit instead of a personal computer. A device according to the invention advantageously enables the analysis and control unit 7 to generate control signals on the basis of which the mode of operation of the power supply 1 is switched over or reprogrammed, for example from a power supply mode to a charger mode. This switchover can be carried out purely in software or using a switch arranged in the respective power supply component, the switching operation of which is controlled by the analysis and control unit 7. Such a switch is indicated by dashed lines in FIGS. 1 and 2 and provided with the reference symbol 2b.
