Description

Die Erfindung betrifft ein Motormanagementsystem mit einem Steuergerät, das über eine Kommunikationsanbindung mit mindestens einem Schalt- und/oder Schutzorgan in einem oder mehreren Verbraucherabzweigen in Verbindung steht, wobei die Kommunikationsanbindung zur Übertragung von Steuer- und/oder Meldesignalen dient.The invention relates to a motor management system with a control unit, which communicates via a communication connection with at least one switching and / or protective device in one or more load branches in connection, wherein the communication connection is used for the transmission of control and / or signaling signals.

Ein derartiges System kommt bei Verbraucherabzweigen, insbesondere bei Motorabzweigen, zum Einsatz. Der Motor ist hier über ein Schaltgerät, zum Beispiel einen Schütz ein- und ausschaltbar, wobei ein Motormanagementsystem als Steuergerät verwendet wird. Das Motormanagementsystem ist über mehrere parallele Leitungen mit dem Schaltgerät verbunden. Die Leitungen dienen jeweils zur Übertragung bestimmter Signale. Zum Beispiel steht eine Leitung zum Ansteuern des Schaltgeräts zur Verfügung. Über weitere Leitungen empfängt das Motormanagementsystem Meldesignale, beispielsweise zur Rückmeldung des Schaltzustands, nachdem ein Schaltsignal an das Schaltgerät übertragen wurde. Weitere Leitungen werden zur Übertragung zusätzlicher Steuer- und Meldesignale eingesetzt, zum Beispiel betreffend den Zustand der Komponenten im Hauptstromkreis des Motors.Such a system is used in load feeders, especially for motor branches. The motor is here via a switching device, for example, a contactor on and off, with an engine management system is used as a control unit. The engine management system is connected to the switching device via several parallel lines. The lines are each used to transmit certain signals. For example, a line is available for controlling the switching device. The motor management system receives signaling signals via further lines, for example for the feedback of the switching state, after a switching signal has been transmitted to the switching device. Other lines are used to transmit additional control and signaling signals, for example regarding the condition of the components in the main circuit of the motor.

Dementsprechend ergibt sich je nach Komplexität der Anwendung erheblicher Aufwand in der Parallelverdrahtung einer Vielzahl von Leitungen, in der Hardware-Projektierung, der Dokumentation, der Fehlervermeidung und gegebenenfalls Fehlersuche.Accordingly arises depending on the complexity of the application considerable effort in the parallel wiring of a variety of lines in the hardware configuration, documentation, error avoidance and possibly troubleshooting.

Daher liegt der Erfindung die Aufgabe zu Grunde, ein Motormanagementsystem der oben genannten Art zu schaffen, das eine einfache und aufwandsarme Anbindung an das Schalt- oder Schutzgerät ermöglicht.Therefore, the invention is based on the object to provide an engine management system of the type mentioned above, which allows a simple and low-cost connection to the switching or protection device.

Die Aufgabe wird dadurch gelöst, dass das Steuergerät über eine Kommunikationsanbindung mit einer vor Ort am Schalt- und/oder Schutzorgan angeordneten Einrichtung zur Umsetzung von Kommunikationssignalen in Steuersignale und/oder von Meldesignalen in Kommunikationssignale verbunden ist.The object is achieved in that the control unit is connected via a communication link to a locally arranged on the switching and / or protective device means for converting communication signals into control signals and / or of signaling signals in communication signals.

Vorteilhafte Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.Advantageous developments of the invention can be found in the dependent claims.

Das in Fig. 1 dargestellte erfindungsgemäße Motormanagementsystem mit direkter Kommunikationsanbindung 2 an das Schalt- oder Schutzorgan 3 eines Motorabzweigs weist ein Steuergerät 1 auf. Hier ist nur beispielhaft die Verbindung des Motormanagementsystems mit einem von üblicherweise mehreren Motorabzweigen gezeigt. Das Steuergerät 1 ist über die Kommunikationsanbindung 2 mit einer vor Ort am Schalt- und/oder Schutzorgan 3 angeordneten Einrichtung 4 verbunden. Die Einrichtung 4 ist hier Bestandteil des Schalt- oder Schutzorgans 3 zum Ein- und Ausschalten des Motors 5 im Motorabzweig. Die Einrichtung 4 setzt die vom Steuergerät 1 über die Kommunikationsanbindung 2 übertragenen Kommunikationssignale in Steuersignale um und leitet diese innerhalb des betreffenden Schalt- oder Schutzorgan 3 zur Ausführung weiter. Z.B. kann das Steuersignal zur Ansteuerung einer Schützspule dienen.This in Fig. 1 illustrated engine management system according to the invention with direct communication link 2 to the switching or protective device 3 of a motor feeder, a control unit 1 on. Here, by way of example only, the connection of the engine management system to one of typically multiple engine branches is shown. The control unit 1 is connected via the communication connection 2 with a locally arranged on the switching and / or protective device 3 means 4. The device 4 is here part of the switching or protective device 3 for switching on and off of the motor 5 in the motor branch. The device 4 converts the communication signals transmitted by the control unit 1 via the communication connection 2 into control signals and forwards them within the relevant switching or protective device 3 for execution. For example, the control signal can be used to control a contactor coil.

Andererseits nimmt die Einrichtung 4 Meldesignale entgegen, zum Beispiel zur Rückmeldung des Schaltzustandes eines hier nicht dargestellten zum Schalt- oder Schutzorgan 3 gehörenden Hilfsschalters, und leitet diese Informationen über die Kommunikationsanbindung 2 an das Steuergerät 1.On the other hand, the device receives 4 alarm signals, for example, to the feedback of the switching state of an auxiliary switch, not shown here belonging to the switching or protective element 3, and passes this information via the communication link 2 to the control unit. 1

Über die elektromechanische Schnittstelle 9 erfolgt nicht nur eine mechanische Verbindung des Koppelmoduls 7 mit dem Schalt- oder Schutzorgan 3, sondern zugleich auch eine elektrische Verbindung, die zur Übertragung der Steuer- und Meldesignale dient. Der ansonsten übliche Verdrahtungsaufwand wird auf diese Weise vermieden. Fig. 2 shows a relation to the embodiment according to Fig. 1 slightly modified embodiment. The device 4 is here part of a coupling module 7, which has a communication interface 8 for coupling the communication connection 2 and an electromechanical interface 9 for coupling the switching or protective device 3. About the electromechanical interface 9 is not only a mechanical connection of the coupling module 7 with the switching or protective device 3, but at the same time an electrical connection, which serves to transmit the control and message signals. The otherwise usual wiring effort is avoided in this way.

Weiterhin weisen sie jeweils eine zusätzliche elektromechanische Schnittstelle 10 auf, über die sie untereinander sowohl elektrisch als auch mechanisch verbunden sind. Nur eines der Koppelmodule 7 ist über seine Kommunikationsschnittstelle 8 an die Kommunikationsanbindung 2 angeschlossen, über das die Übertragung der Steuer- und Meldesignale erfolgt. Fig. 3 shows an embodiment of an engine management system according to the invention, in which a plurality of coupling modules 7 are in use, which may be constructed in the same manner as described above. Furthermore, they each have an additional electromechanical interface 10, via which they are connected to each other both electrically and mechanically. Only one of the coupling modules 7 is connected via its communication interface 8 to the communication connection 2, via which the transmission of the control and message signals takes place.

Das Steuergerät 1 des oben beschriebenen erfindungsgemäßen Motormanagementsystems ist mit mindestens einem Speicher 11 und einer Auswerteeinheit 12 ausgestattet. Der Speicher 11 dient zum Abspeichern mindestens eines motorspezifischen Kennwertes und die Auswerteeinheit 12 zum Auswerten von Motorzustandsdaten der vom Motormanagementsystem gesteuerten Motoren.The control unit 1 of the engine management system according to the invention described above is equipped with at least one memory 11 and an evaluation unit 12.
