Description

Die Erfindung betrifft eine Anordnung zur ferngesteuerten Überwachung und Beeinflussung eines elektronischen Überstrom­ auslösers eines elektrischen Leistungsschalters, wobei der Überstromauslöser eine Schnittstelle zur Ausgabe von Zustandsmeldungen und zum Empfang von Steuerbefehlen besitzt und die Schnittstelle mit einer Übertragungsleitung verbunden ist.The invention relates to an arrangement for remote control Monitoring and influencing an electronic overcurrent Triggers an electrical circuit breaker, the Overcurrent release an interface for the output of Status messages and to receive control commands and the interface is connected to a transmission line is.

Anordnungen der genannten Art sind in der verschiedenen Ausführungen bekanntgeworden. Als Beispiele wird auf folgende Patentdokumente verwiesen: DE 31 22 109 C2, US 3 918 566 A und US 5 373 412 A. Auf der Übertragungsleitung kommen bei diesen Anordnungen spezielle Protokolle der Datenübertragung zur Anwendung. Soweit es sich dabei nicht um spezielle lokale Netze handelt, kann die Datenübertragung auch über Energie­ leitungen erfolgen, wenn die betreffende Anordnung zur Fernsteuerung von Abnehmerschaltern durch die zentrale Lastverteilung eines Energieversorgungsunternehmens erfolgen soll.Arrangements of the type mentioned are in different Executions became known. Examples are given below Patent documents referenced: DE 31 22 109 C2, US 3 918 566 A and US 5,373,412 A. On the transmission line come in special protocols for data transmission to use. As far as it is not special local Networks, data transmission can also be via energy lines take place if the relevant arrangement for Remote control of customer switches through the central Load distribution of an energy supply company should.

In der Praxis handelt es sich jedoch nicht nur darum, die Überstromauslöser von Leistungsschaltern mit einer zentralen Warte zu verbinden, sondern auch eine zentrale Überwachung und Fernbedienung von Leistungsschaltern und zugehörigen Überstromauslösern durch den Hersteller zu ermöglichen. Diese Vorgänge sind mit Hilfe der bisher verfügbaren Anordnungen nur mit großen Aufwand erfüllbar, weil entweder ein eigenes Datennetz zur Verbindung der einzelnen Leistungsschalter mit dem Hersteller der Schaltgeräte errichtet oder wenigstens eine mehrfache Umsetzung von Datenformaten vorgenommen werden muß. Der Erfindung liegt die Aufgabe zugrunde, die Betreuung von Leistungsschaltern und Überstromauslösern durch eine zentrale Warte wesentlich kostengünstiger und technisch einfacher zu gestalten.In practice, however, it is not just about the Overcurrent release of circuit breakers with a central Wait to connect, but also central monitoring and remote control of circuit breakers and related To enable overcurrent releases by the manufacturer. This Operations are done using the arrangements available so far  can only be achieved with great effort, because either your own Data network for connecting the individual circuit breakers with the manufacturer of the switchgear, or at least multiple conversion of data formats can be carried out got to. The invention is based, the care of the task of circuit breakers and overcurrent releases by one central control room much cheaper and technically easier to design.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß die Übertragungsleitung Bestandteil eines Datenverarbeitungs­ geräte verbindenden Netzwerkes ist und daß die Schnittstelle des Überstromauslösers für den Austausch von Daten gemäß der TCP/IP-Protokollreihe im HTML-Format eingerichtet ist. Damit entfällt die bisherige Einrichtung spezieller Fernsteuerungs- Bussysteme (z. B. Profibus o. ä.).This object is achieved according to the invention in that the transmission line is part of a data processing system device connecting network and that the interface of the overcurrent release for the exchange of data according to the TCP / IP protocol series is set up in HTML format. In order to the previous establishment of special remote control Bus systems (e.g. Profibus or similar).

Die Datenübertragung mittels der TCP/IP-Protokollreihe ist zur Verbindung von Computern (PC) im weltweiten Rahmen über das Internet eingeführt. Dies bedeutet, daß an beliebigen Stellen der Erde befindliche PC-artige Datenverarbeitungs­ geräte auch unterschiedlicher Systeme miteinander zwecks Datenaustausches in Verbindung gebracht werden können. Das hierbei eingesetzte HTML-Format gestattet dabei eine direkte Ein- und Ausgabe von Informationen bzw. Daten unter Heranziehung weiterer Datenquellen oder Datenbanken, gleich­ gültig, ob diese mit dem betreffenden Datenverarbeitungsgerät direkt oder über das Internet verbunden sind.The data transfer using the TCP / IP protocol series is for the connection of computers (PC) worldwide introduced the internet. This means that at any PC-type data processing located on earth devices of different systems with each other for the purpose Data exchange can be linked. The HTML format used here allows direct Input and output of information or data under Using other data sources or databases, the same valid whether this with the relevant data processing device connected directly or via the internet.

Die Benutzung einer Datenübertragung nach der TCP/IP-Proto­ kollreihe über eine Internetverbindung ermöglicht es, beispielsweise dem Hersteller eines Leistungsschalters, auf Anforderung einen an beliebiger Stelle der Erde befindlichen Leistungsschalter durch Abfrage seines elektronischen Überstromauslösers zu untersuchen und diesem im Bedarfsfall Befehle, Daten oder veränderte Parameter zu übermitteln. Trotz des hierdurch ermöglichten weltweiten Zugriffes auf die Eigenschaften der Überstromauslöser von Leistungsschaltern kann dafür gesorgt sein, daß keine gefahrbringenden oder unerlaubten Zugriffe erfolgen. Im einfachsten Fall kann dies dadurch geschehen, daß der Überstromauslöser mit einem Schalter versehen ist, der eine Veränderung von Auslöser­ parametern mittels Datenübertragung über die Schnittstelle freigibt, bzw. sperrt. Auf diese Weise kann der Zugriff durch den Hersteller in einem engen zeitlichen Rahmen mit dem Betreiber des Leistungsschalters abgesprochen werden und somit anschließend ein unerlaubter Zugriff ausgeschlossen ist. Im übrigen können Verschlüsselungsalgorythmen, Paßwörter oder ähnliche Sicherheitsmerkmale zum Einsatz kommen, wie sie beispielsweise auch bei Bankgeschäften im Internet benutzt werden.The use of data transmission according to the TCP / IP proto coll series via an internet connection enables  for example, the manufacturer of a circuit breaker Require one anywhere in the world Circuit breaker by querying its electronic Overcurrent release to investigate and if necessary To transmit commands, data or changed parameters. Despite the global access to the Features of circuit breaker overcurrent releases can be ensured that no dangerous or unauthorized access. In the simplest case, this can be done happen that the overcurrent release with a Switch is provided, which is a change of trigger parameters by means of data transfer via the interface releases or blocks. That way, access can be through the manufacturer in a tight time frame with the Circuit breaker operators can be discussed and unauthorized access is subsequently excluded is. Incidentally, encryption algorithms, passwords or similar security features are used as they are used for example in banking transactions on the Internet will.

Der datentechnische Umfang einer Seite im HTML-Format ist verhältnismäßig klein. Diese Tatsache kann im Rahmen der Erfindung in der Weise ausgewertet werden, daß in einem Speicherbereich des Überstromauslösers wenigstens eine zur Abfrage bereitgehaltene HTML-Seite gespeichert ist. Dies hat den Vorteil, daß der Umfang zu übertragender Daten bedarfs­ gerecht beschränkt werden kann. Hierdurch wird durchschnitt­ lich eine bedeutende Einsparung von Speicherplatz erreicht, verglichen damit, daß grundsätzlich eine für den größten anfallenden Datensatz benötigte Seite benutzt wird. The data processing scope of a page in HTML format is relatively small. This fact can be seen in the Invention can be evaluated in such a way that in a Storage area of the overcurrent release at least one for The HTML page provided is saved. this has the advantage that the amount of data to be transferred is required can be fairly limited. This will average achieved a significant saving in storage space, compared to the fact that basically one for the largest resulting data record required page is used.  

Ferner wirkt es sich als vorteilhaft aus, wenn der genannte Speicherbereich zum Abruf und zur Ablage wenigstens einer HTML-Seite lesbar und beschreibbar ausgebildet ist. In diesem Fall können sowohl Betreiber und Hersteller bzw. Wartungs­ dienst des Leistungsschalters angepaßte HTML-Seiten im Überstromauslöser hinterlegen oder ersetzen.It also has an advantageous effect if the said Memory area for retrieving and storing at least one HTML page is readable and writable. In this Case can be both operator and manufacturer or maintenance service of the circuit breaker customized HTML pages in the Store or replace overcurrent release.

Die Erfindung wird im folgenden anhand des in der Figur dargestellten Ausführungsbeispieles näher erläutert.The invention is based on the in the figure illustrated embodiment explained in more detail.

Die Figur zeigt aus einer großen Anzahl von Leistungs­ schaltern einen Leistungsschalter LS1, einen weiteren Leistungsschalter LS2 sowie unter Auslassung der unmittelbar folgenden Ordnungsnummern einen weiteren Leistungsschalter LSn. Jeder dieser Leistungsschalter besitzt einen Überstrom­ auslöser U1, U2 bzw. Un, der mit einer Schnittstelle S1, S2, Sn ausgerüstet ist. Mittels dieser Schnittstellen sind die Leistungsschalter LS1, LS2 und LSn mit Netzwerken NW1, NW2 verbunden, die durch örtliche Abschnitte des Internet gebildet sind. In der Figur ist angedeutet, daß die Teile des Netzwerkes NW1 und NW2 räumlich weit auseinanderliegen und sich beispielsweise auf unterschiedlichen Kontinenten befinden können. Sie stehen in dem gezeigten Beispiel über Antennen A1 und A2 mit einen Satelliten S in Verbindung, der für die ständige Verfügbarkeit der Verbindung sorgt.The figure shows a large number of performance switch one circuit breaker LS1, another Circuit breaker LS2 as well as omitting the immediately following order numbers another circuit breaker LSn. Each of these circuit breakers has an overcurrent trigger U1, U2 or Un, which has an interface S1, S2, Sn is equipped. By means of these interfaces, the Circuit breakers LS1, LS2 and LSn with networks NW1, NW2 connected by local sections of the internet are formed. In the figure it is indicated that the parts of the Networks NW1 and NW2 are spatially far apart and for example on different continents can be located. They protrude in the example shown Antennas A1 and A2 in connection with a satellite S which ensures the constant availability of the connection.

Mit dem Netzwerk NW1 und NW2 stehen in beliebiger Anzahl Datenverarbeitungsgeräte in der Gestalt von Personalcomputern PC1, PC2 usw. in Verbindung. Dabei kann es sich sowohl um Datenverarbeitungsgeräte der Betreiber der Leistungsschalter LS1, LS2 usw. oder der Hersteller dieser Leistungsschalter handeln. Ein externes Moden M oder eine entsprechende interne Modemkarte ermöglichen dabei den Datenaustausch zwischen einem überall zugänglichen öffentlichen Telefonnetz und dem Internet.With the network NW1 and NW2 there are any number Data processing equipment in the form of personal computers PC1, PC2 etc. in connection. It can be both Data processing equipment of circuit breaker operators  LS1, LS2 etc. or the manufacturer of these circuit breakers act. An external mode M or a corresponding internal one Modem cards enable data exchange between a public telephone network accessible everywhere and the Internet.

Im folgenden wird der Fall betrachtet, daß ein Betreiber von Leistungsschaltern den Hersteller beauftragen möchte, die zugehörigen Überstromauslöser zu prüfen und die Einstellung von Parametern zu modifizieren, falls dies erforderlich erscheint. Dies kann dadurch geschehen, daß der Betreiber dem Hersteller eine schriftliche, telefonische oder über das Netzwerk NW1 bzw. NW2 übertragene Mitteilung zukommen läßt. Hierbei spezifiziert der Betreiber den Zeitraum, zu dem die Wartungsarbeiten durchgeführt werden sollen oder erklärt sich bereit, die Überstromauslöser auf Anforderung zu einem bestimmten Zeitpunkt zur Datenübertragung über das Netzwerk NW1 bzw. NW2 zugänglich zu machen. Der Hersteller nimmt nun mittels seines Datenverarbeitungsgerätes, z. B. PC1, in der gleichen Weise durch Eingabe einer Internet-Adresse Kontakt mit der elektrischen Anlage des Betreibers auf, wie dies bei anderen Informations- und Datendiensten des Internet der Fall ist. Durch Anwahl der betreffenden Überstromauslöser U1, U2 usw. erhält nun der Hersteller eine Bildschirmdarstellung, der registrierten Vorgänge. Der Umfang dieser Registrierung hängt von Anforderungen des Betreibers und/oder des Her­ stellers ab und erfordert eine entsprechende Ausrüstung des Überstromauslösers mit einem Datenspeicher. Im vorliegenden Zusammenhang interessierende Daten können insbesondere erfolgte Auslösungen mit der Angabe des Überstromes sein. Nun kann der Hersteller mittels in dem Datenverarbeitungsgerät PC1 oder einer externen Datenbank DB gespeicherten Daten ermitteln, ob die Auslösungen in einem vorgegebenen Rahmen liegen oder ob es unter Berücksichtigung der Konfiguration der Anlage des Betreibers zweckmäßig ist, veränderte Auslöse­ parameter einzustellen. Sofern sich dies ergibt kann nun die Einstellung des Überstromauslösers U1 durch Übertragung eines veränderten Satzes von Parametern direkt vorgenommen werden. Zur Sicherheit des Betreibers kann diesem die Vornahme der Änderung bestätigt oder protokolliert werden, damit der Betreiber anschließend den weiteren Zugang unterbrechen kann, um dadurch weitere Änderungen von Parametern auszuschließen. Umgekehrt kann dem Hersteller der Zugriff weiterhin ermöglicht werden, damit dieser sich von dem Wirksamwerden bzw. der Auswirkung der vorgenommenen Änderungen der eingestellten Parameter überzeugen kann.In the following, the case is considered that an operator of Circuit breakers to commission the manufacturer who Check the associated overcurrent release and the setting of parameters to modify if necessary appears. This can be done in that the operator Manufacturer a written, telephone or via the Network NW1 or NW2 transmitted message. The operator specifies the period during which the Maintenance work should be carried out or explains itself ready to release the overcurrent release on request specific point in time for data transmission over the network Make NW1 or NW2 accessible. The manufacturer now takes by means of his data processing device, e.g. B. PC1, in the same way by entering an internet address contact with the operator's electrical system on how this at other information and data services on the Internet is. By selecting the relevant overcurrent release U1, U2 etc. the manufacturer now receives a screen display, of the registered transactions. The scope of this registration depends on the requirements of the operator and / or the manufacturer and requires the appropriate equipment from the Overcurrent release with a data storage. In the present Data of interest can in particular tripping with indication of overcurrent. Now the manufacturer can by means in the data processing device  PC1 or an external database DB stored data determine whether the triggers within a given framework lie or whether it is considering the configuration the operator's plant is appropriate, changed triggers set parameters. If this results, the Setting the overcurrent release U1 by transferring a changed set of parameters can be made directly. For the safety of the operator, the operator can carry out the Changes are confirmed or logged so that the Operator can then interrupt further access, to exclude further changes to parameters. Conversely, the manufacturer can still access be made possible so that it can take effect or the impact of the changes made set parameters can convince.

Die erwähnte Bildschirmdarstellung, die im Rahmen der Wartungsarbeiten am Datenverarbeitungsgerät PC1 erscheint, ist vorzugsweise wenigstens eine Seite im HTML-Format, die in einem Speicherbereich des angewählten Überstromauslösers abrufbar gespeichert ist, z. B. Speicherbereich SP1 im Überstromauslöser U1 des Leistungsschalters LS1. Diese HTML-Seite bildet den Rahmen und die Benutzeroberfläche zum Lesen und Verändern von Daten. Es kann vorgesehen sein, daß der Benutzer des Leistungsschalters selbst die HTML-Seite bereitstellt und damit vorgibt, welche Daten im Rahmen der Wartung zugänglich sind. Andererseits kann auch eine solche Konfiguration gewählt werden, daß der Hersteller des Leistungsschalters bzw. der beauftragte Wartungsdienst die HTML-Seite bereitstellt und im Verlauf der Wartungsarbeiten bei Bedarf austauscht oder verändert. Dies ist dadurch möglich, daß der Speicherbereich beschreibbar ausgebildet und der Schreibmodus freigegeben bzw. durch Paßwortübertragung freigebbar ist.The aforementioned screen display, which is part of the Maintenance work on the data processing device PC1 appears, is preferably at least one page in HTML format that is in a memory area of the selected overcurrent release is stored, e.g. B. memory area SP1 in Overcurrent release U1 of the circuit breaker LS1. This HTML page forms the framework and the user interface for reading and changing data. It can be provided that the Circuit breaker users themselves the HTML page provides and thus specifies which data within the scope of the Maintenance are accessible. On the other hand, such Configuration that the manufacturer of the Circuit breaker or the commissioned maintenance service Provides HTML page and in the course of maintenance work exchanged or changed if necessary. This is because of it  possible that the memory area is designed to be writable and the write mode enabled or by password transmission can be released.
