Weitere Einzelheiten und Vorteile der Erfindung ergeben sich aus dem folgenden, anhand zweier Figuren erläuterten Ausführungsbeispiel.Further details and advantages of the invention result from the following embodiment explained with reference to two figures.
Der Aufbau einer erfindungsgemäßen Schaltvorrichtung ist schematisch in Fig. 1 dargestellt. Die Schaltvorrichtung basiert auf einem üblichen Schaltgerät, zum Beispiel einem Leistungsschalter, Motorschutzrelais oder ähnlichem, mit einem Gehäuse 2 umfassend eine hier aus drei Stromwandlern bestehende Stromerfassungseinrichtung 4, die zur Erfassung der in den Leitern 21, 22, 23 fließenden Ströme dient, einer Einheit 6, die die von den Wandlern kommenden Messsignale zur weiteren Verarbeitung aufbereitet und gleichzeitig daraus die Stromversorgung für die gesamte Elektronik erzeugt, einer im wesentlichen aus einem Mikroprozessor (inkl. notwendiger Peripherie) bestehenden Steuereinrichtung 8, welche die Verarbeitung der gemessenen Ströme übernimmt und einer Auslöseeinheit 10, die die Unterbrechereinrichtung 11 (Schaltkontakte, z. B. mechanisch oder halbleitertechnisch) des Schalters bei Erreichen einer der zuvor eingestellten Bedingungen betätigt. Diese Bedingungen können über ein Bedienfeld 12, eine drahtgebundene serielle Schnittstelle 14a (optional) und/oder erfindungsgemäß über Signale der Stromversorgungsleitungen 21, 22, 23 vorgegeben werden. In einer besonders bevorzugten Ausführungsform der Erfindung ist das Schaltgerät sowohl mit Mitteln 14c zur Ein- bzw. Auskopplung von Daten in/aus den Stromversorgungsleitungen und/oder mit einer drahtlosen Schnittstelle 14b, vorzugsweise einem Funk-Interface zum Beispiel auf Basis des bekannten Bluetooth-Konzepts und/oder mit einer drahtgebundenen Schnittstelle 14a zum Anschluß an ein Bussystem ausgeführt.The structure of a switching device according to the invention is shown schematically in FIG. 1. The switching device is based on a conventional switching device, for example a circuit breaker, motor protection relay or the like, with a housing 2 comprising a current detection device 4 , which here consists of three current transformers and serves to detect the currents flowing in the conductors 21 , 22 , 23 , a unit 6 , which processes the measurement signals coming from the transducers for further processing and at the same time generates the power supply for the entire electronics from them, a control device 8 consisting essentially of a microprocessor (including the necessary peripherals), which takes over the processing of the measured currents and a trigger unit 10 which actuates the interrupter device 11 (switching contacts, e.g. mechanically or semiconductively) of the switch when one of the previously set conditions is reached. These conditions can be specified via a control panel 12 , a wired serial interface 14 a (optional) and / or according to the invention via signals from the power supply lines 21 , 22 , 23 . In a particularly preferred embodiment of the invention, the switching device is provided with means 14 c for coupling and decoupling data into / from the power supply lines and / or with a wireless interface 14 b, preferably a radio interface, for example based on the known Bluetooth -Concept and / or with a wired interface 14 a for connection to a bus system.
Über die Koppelmittel 14c kann die erfindungsgemäße Schaltvorrichtung mit anderen ggf. örtlich sehr weit entfernten Geräten, die ebenfalls derartige Koppeleinrichtungen aufweisen, kommuniziern, ohne zusätzlich mit diesen verdrahtet zu sein. Einzige Voraussetzung ist der Anschluß an das gemeinsame Stromversorgungsnetz (siehe auch Fig. 2). Hierdurch ist ein Datenaustausch wie der beim Internet zwischen über die Welt verteilten Schalteinrichtungen problemlos möglich. Vorzugsweise erfolgt auch die Datenübertragung mittels Internet-Protokoll.Via the coupling means 14 c, the switching device according to the invention can communicate with other devices which may be very far away and which also have such coupling devices without being additionally wired to them. The only requirement is connection to the common power supply network (see also Fig. 2). As a result, data exchange such as that of the Internet between switching devices distributed around the world is possible without any problems. The data transmission is preferably also carried out using the Internet protocol.
Über die drahtlose Schnittstelle 14b kann das Schaltgerät mit anderen Teilnehmern in einem (räumlich eng begrenzten) Umfeld kommunizieren, also z. B. aktuelle Messdaten oder Statusmeldungen ausgeben oder Parameter austauschen.Via the wireless interface 14 b, the switching device can communicate with other participants in a (spatially limited) environment, that is, for. B. output current measurement data or status messages or exchange parameters.
Desweiteren ist die Schaltvorrichtung mit einer Anzeigeeinheit 13 in Form eines integrierten Displays versehen. Über dieses Display 13 können Zustandsdaten und Fehlermeldungen angezeigt werden. Weiterhin ist vorgesehen auch die Programmier- oder Parametrierschritte bzw. -daten anzuzeigen, so dass über ein einfaches Programmiergerät ohne eigene Anzeigeeinheit Parameter und/oder Programme einfach ausgewählt, eingestellt und über die Anzeige am Schaltgerät selbst angezeigt und kontrolliert werden können. Im einfachsten Fall wird über einen einfachen Sender (als Programmiergeräteersatz) mit n verschiedenen Sendesignalen eines von n im Schaltgerät hinterlegten Betriebsprogrammen einfach ausgewählt und aktiviert. Dieser Vorgang kann dann über die Anzeigeeinheit 13 des Schaltgerätes selbst angezeigt und kontrolliert werden.Furthermore, the switching device is provided with a display unit 13 in the form of an integrated display. Status data and error messages can be shown on this display 13 . Furthermore, it is also provided to display the programming or parameterization steps or data, so that parameters and / or programs can be easily selected, set and displayed and checked via the display on the switching device itself using a simple programming device without its own display unit. In the simplest case, a simple transmitter (as a replacement for programming devices) with n different transmission signals is used to simply select and activate one of n operating programs stored in the switching device. This process can then be displayed and checked via the display unit 13 of the switching device itself.
Bevorzugte Anwendungen finden sich in der Kommunikation zwischen Schaltgerät und einem Diagnose- oder Parametriergerät (PC, PDA o. a.) am Einsatzort des Schaltgeräts (Diagnose, Parametrierung, Wartung). Hierdurch wird das Ändern der Parameter durch Bedienpersonal vor Ort gewährleistet, ohne dass das Schaltgerät selbst berührt werden muss. Dadurch kann z. B. ein Sicherheitsabstand gewahrt bleiben. Die Möglichkeit zur Beeinflussung des Schaltgeräts besteht aber weiterhin, auch ohne eine aufwändige Vernetzung realisieren zu müssen.Preferred applications can be found in the communication between Switchgear and a diagnostic or parameterization device (PC, PDA or the like) on Location of the switchgear (diagnosis, parameterization, maintenance). hereby the changing of the parameters is guaranteed by operating personnel on site, without having to touch the switching device itself. This can, for. B. a Keep a safe distance. The possibility to influence the Switchgear continues to exist, even without complex networking to have to realize.
Eine weitere Anwendung findet sich in der Kommunikation zwischen Schaltgerät und Diagnose- oder Parametriergerät (PC, PDA o. a.) am Einsatzort des Schaltgeräts bei gleichzeitiger (optionaler) Ankopplung des Schaltgeräts an einen Feldbus (z. B. über den UART) und die drahtgebundene serielle Datenübertragung. Beispiel: Abfrage der Diagnosedaten durch Wartungspersonal vor Ort, wobei gleichzeitig der Feldbus-Anschluss bestehen bleibt.Another application is in communication between Switchgear and diagnostic or parameterization device (PC, PDA or similar) on Location of the switching device with simultaneous (optional) coupling of the Switchgear to a fieldbus (e.g. via the UART) and the wired serial data transmission. Example: Query the diagnostic data by Maintenance personnel on site, whereby the fieldbus connection is also available remains.
Auch der drahtlose Austausch von Signalen zwischen Schaltgeräten die deren Verhalten beeinflussen (z. B. Selektivität) ist somit einfach realisierbar.Also the wireless exchange of signals between switching devices Influencing behavior (e.g. selectivity) is therefore easy to implement.
Als weitere Möglichkeit kann über die Funkstrecke hilfsweise auch die Betriebsenergie für die drahtlose Schnittstelle 14b übertragen werden. Dadurch wird es möglich, zumindest eine einfache Zustandsabfrage (OK, ausgefallen, . . .) des Schaltgeräts durchzuführen, ohne dass es sich selbst in Betrieb befindet. Dies wäre z. B. für selbstversorgende Geräte interessant, wenn die in den Leitern 21, 22, 23 fließenden Ströme nicht zum Betrieb der Elektronik ausreichen.As another option, the operating power for the wireless interface 14 can be transmitted via the radio link b alternative. This makes it possible to carry out at least a simple status query (OK, failed,...) Of the switching device without it being in operation. This would be e.g. B. interesting for self-supplying devices if the currents flowing in the conductors 21 , 22 , 23 are not sufficient to operate the electronics.
Fig. 2 zeigt die schematische Anordnung verschiedener erfindungsgemäßer Schaltvorrichtungen in einer Netztopologie mit verschiedenen Teilnehmern. Dabei sind die erfindungsgemäßen Schaltvorrichtungen an ein Niederspannungsnetz angeschlossen, über welches sie Daten durch Einkopplung bzw. Auskopplung in bzw. aus ihren Stromversorgungsleitungen 21, 22, 23 senden bzw. empfangen. Andere Teilnehmer wie Personalcomputer, lokale Steuereinrichtungen und Internetserver sind ebenfalls an das Niederspannungsnetz angeschlossen. Zur Verstärkung der zu übertragenden Signale sind in Abständen Verstärkerbaugruppen in das Niederspannungsnetz eingebunden. Fig. 2 shows the schematic arrangement of various switching devices according to the invention in a network topology with different participants. The switching devices according to the invention are connected to a low-voltage network via which they send or receive data by coupling or decoupling them into or from their power supply lines 21 , 22 , 23 . Other participants such as personal computers, local control devices and internet servers are also connected to the low-voltage network. To amplify the signals to be transmitted, amplifier modules are integrated into the low-voltage network at intervals.
