Abstract

The method involves a computer network which transmits data to different points in a building, by using the earth and ground leakage current protection lines of the lighting system wiring. The earth line is identified and this results in a relay being operated to connect the output of the transmittance unit to the receiver. Diodes are provided in the line to minimise the disturbance effect of defective components. The computer generated data can be amplitude or frequency modulated.

Description

Die Erfindung betrifft ein Verfahren gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a method according to the preamble of claim 1.

Es ist bekannt, daß Rechnerdaten über direkte Verbindungsleitungen, Telefonleitungen und über Funk übertragen werden können. Bei diesen Verfahren wird die RS232 Rechnerschnittstelle zum Senden und Empfangen der Rechnerdaten verwendet. Die Verbindungsleitungen der Rechner sollten bei diesen Verfahren möglichst frei von äußeren Störeinflüssen sein, um eine sichere Datenübertragung zu gewährleisten. Nicht von der Übertragung abzuwendende Störungen können durch programmtechnische Fehlerkorrekturen erfaßt und beseitigt werden.It is known that computer data via direct connection lines, telephone lines and Radio can be transmitted. With this procedure the RS232 computer interface becomes Sending and receiving the computer data used. The connecting lines of the computers These procedures should be as free as possible from external interference in order to ensure safe To ensure data transmission. Faults that cannot be averted from the transmission can be detected and corrected by programming errors.

Ferner ist bekannt, daß die RS232 Rechnerschnittstelle die einzelnen Zeichen von Rechnerdaten in Form von Binär-Codierungen ausgibt und ebenfalls solche Binär-Codierungen von Zeichen empfangen kann. Dabei kann die Ausgabegeschwindigkeit, also auch die Übertragungsgeschwindigkeit der RS232 Rechnerschnittstelle verändert werden.It is also known that the RS232 computer interface the individual characters of computer data outputs in the form of binary codes and also such binary codes of characters can receive. The output speed, including the Transmission speed of the RS232 computer interface can be changed.

Die Vernetzung von Rechnern in Gebäuden ist meist sehr kostspielig, da das Verlegen von Verbindungsleitungen sehr aufwendig ist. Alternativen wie die Datenübertragung durch das Telefonnetz oder über Funkverbindungen haben den Nachteil, daß ständig Kosten in Form von Telefongebühren bei der Datenübertragung durch das Telefonnetz oder Funklizenzgebühren bei der Datenübertragung über Funk anfallen. Hausinterne Telefonanlagen, die auch für die Rechnerdatenübertragung geeignet und gleichzeitig ohne laufende Gebühren sind, haben den Nachteil eines sehr hohen Anschaffungspreises. Funkverbindungen ohne laufende Kosten müßten auf den allgemein frei benutzbaren Frequenzen liegen und wären damit stark durch andere Benutzer dieser Frequenzen gestört. The networking of computers in buildings is usually very expensive because the laying of Connection lines is very expensive. Alternatives such as data transmission through the Telephone network or radio connections have the disadvantage that costs in the form of Telephone charges for data transmission through the telephone network or radio license fees radio data transmission. In-house telephone systems, also for the Computer data transmission is suitable and at the same time without running fees, have the Disadvantage of a very high purchase price. Radio connections would have to be without running costs lie on the generally freely usable frequencies and would therefore be strong by others Users of these frequencies are disturbed.  

Aufgabe der Erfindung ist es, Rechnerdaten innerhalb eines Gebäudes zu übertragen, wobei bei der Anwendung der Erfindung keine laufenden Kosten entstehen sollen und die Installation der Erfindung mit geringem Aufwand und somit auch mit geringen Kosten verbunden sein soll. Ebenfalls soll der Anschaffungspreis der Erfindung, im Verhältnis zu ihrer Leistung gesehen, aufgrund der einfachen Funktionsweise gering sein.The object of the invention is to transmit computer data within a building, with the application of the invention should not incur any ongoing costs and the installation of the Invention with little effort and thus should also be associated with low costs. Likewise, the purchase price of the invention, in relation to its performance, be small due to the simple functioning.

Diese Aufgabe wird durch ein Verfahren mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a method with the features of claim 1.

Durch das Verfahren zur Rechnerdatenübertragung durch das Lichtstromnetz wird die Vernetzung von Rechnern innerhalb eines Gebäudes einfacher, da die Rechner nur über die Erfindung mit dem Lichtstromnetz verbunden werden müssen. In den meisten Gebäuden kann auf das Lichtstromnetz von fast jedem Raum aus zugegriffen werden. Das bedeutet, daß bei der Vernetzung von Rechnern durch das Lichtstromnetz, durch ein Verfahren mit den Merkmalen des Anspruchs 1, ein bereits vorhandenes Netzwerk, nämlich das Lichtstromnetz, gleichzeitig als Rechnerdatennetz verwendet wird, wodurch keine zusätzlichen Netzwerke benötigt werden.The procedure for computer data transmission through the luminous flux network means that Networking of computers within a building is easier, since the computers can only be accessed via the Invention must be connected to the luminous flux network. Most buildings can the luminous flux network can be accessed from almost every room. That means that at the Networking of computers through the luminous flux network, using a process with the features of claim 1, an existing network, namely the luminous flux network, simultaneously as Computer data network is used, which means that no additional networks are required.

Durch das Verfahren zur Rechnerdatenübertragung durch das Lichtstromnetz wird die Vernetzung von Rechnern innerhalb eines Gebäudes sehr viel einfacher, da keine Datenleitungen verlegt werden müssen.The procedure for computer data transmission through the luminous flux network means that Networking computers within a building is much easier because there are no data lines must be relocated.

Die Erfindung verursacht bei ihrem Einsatz keine laufenden Kosten.The invention does not cause any running costs when used.

Die Rechnerdatenübertragung unter Einsatz der Erfindung interferiert nicht mit anderen Übertragungssystemen, wie z. B. Funk.Computer data transmission using the invention does not interfere with others Transmission systems, such as B. radio.

Durch Verwendung von Trägerfrequenzen bei dem Verfahren zur Datenübertragung können mehrere dieser Übertragungssysteme innerhalb eines Fehlerstromschutzbereiches unabhängig voneinander betrieben werden.By using carrier frequencies in the method for data transmission several of these transmission systems are independent within a residual current protection area operated from each other.

Die Anschaffungskosten der Erfindung sind gering. The cost of the invention is low.  

Der Datenübertragungsbereich der Erfindung kann durch eine Vorrichtung mit den Merkmalen des Anspruchs 5 von einem auf mehrere Fehlerstromschutzbereiche ausgedehnt werden. The data transmission range of the invention can be achieved by a device with the features of claim 5 can be extended from one to several residual current protection areas.  

Ein Ausführungsbeispiel der Erfindung ist in Form eines Schaltplanes dargestellt und wird im folgenden näher erläutert.An embodiment of the invention is shown in the form of a circuit diagram and will explained in more detail below.

Abb. 1: Schaltbeispiel für eine Vorrichtung, die Rechnerdaten über die Masseleitung und die Fehlerstromschutzleitung des Lichtstromnetzes überträgt. Fig. 1: Circuit example for a device that transmits computer data via the ground line and the residual current protective line of the luminous flux network.

Die Schaltung läßt sich in drei zusammenwirkende Teile unterteilen:The circuit can be divided into three interacting parts:

  • 1. Den Teil, der die Masse des Lichtstromnetzes ermittelt, im folgenden "Suchteil" genannt.1. The part that determines the mass of the luminous flux network in the following "search part" called.
  • 2. Den Teil, der die Rechnerdaten verstärkt und in das Lichtstromnetz sendet, im folgenden "Sendeteil" genannt.2. The part that amplifies the computer data and sends it to the luminous flux network in the called the following "broadcasting section".
  • 3. Den Teil, der die Rechnerdaten aus dem Lichtstromnetz empfängt, im folgenden "Empfangsteil" genannt.3. The part that receives the computer data from the luminous flux network in the following Called "receiving part".

Der Suchteil (1) der Schaltung ermittelt die Masse des Lichtstromnetzes, da diese aus den Anschlüssen einer Steckdose nicht ersichtlich ist. Die Masse muß ermittelt werden, damit die Rechnerdaten über die Masse und die Fehlerstromschutzleitung des Lichtstromnetzes gesendet werden können. Sobald die Masse durch den Suchteil (1) gefunden wurde, wird sie mit dem Ausgang des Sendeteils (2) und dem Eingang des Empfangsteils (3) über ein Relais verbunden. Es ist von Vorteil, vor den Eingang des Empfangsteils (3) und hinter den Ausgang des Sendeteils (2) Dioden zu schalten, damit Störungen in den Leitungen teilweise abgeschwächt oder ganz von den Teilen 1 und 2 abgehalten werden.The search part ( 1 ) of the circuit determines the mass of the luminous flux network, since this cannot be seen from the connections of a socket. The mass must be determined so that the computer data can be sent via the mass and the residual current protective line of the luminous flux network. As soon as the mass has been found by the search part ( 1 ), it is connected to the output of the transmitting part ( 2 ) and the input of the receiving part ( 3 ) via a relay. It is advantageous to switch diodes in front of the input of the receiving part ( 3 ) and behind the output of the transmitting part ( 2 ), so that interference in the lines is partially weakened or completely prevented by parts 1 and 2 .

Um eine Beschädigung der an die Schaltung angeschlossenen Rechner im Falle einer durch defekte Bauteile auf der Schaltung verursachten Fehlfunktion zu vermeiden, sind die Leitungen der Rechnerschnittstellen durch optoelektronische Koppelelemente von der Schaltung getrennt.To damage the computer connected to the circuit in the event of a through to avoid defective components on the circuit causing malfunction Lines of the computer interfaces through optoelectronic coupling elements from the Circuit separated.

Die Sendeleistung des Sendeteils (2) und die Empfindlichkeit des Empfangsteils (3) lassen sich verstellen, um die Schaltung an verschiedene Lichtstromsysteme anpassen zu können. The transmission power of the transmitting part ( 2 ) and the sensitivity of the receiving part ( 3 ) can be adjusted in order to be able to adapt the circuit to different luminous flux systems.

In einer nicht dargestellten Ausführung bewirken die zu übertragenden Rechnerdaten eine Amplitudenmodulation oder eine Frequenzmodulation einer in die Masseleitung und die Fehlerstromschutzleitung gesendeten hohen Frequenz. Im Empfangsteil wird diese modulierte Frequenz wieder demoduliert, und die demodulierten Rechnerdaten werden dann an den empfangenden Rechner weitergeleitet.In an embodiment not shown, the computer data to be transmitted cause one Amplitude modulation or a frequency modulation one into the ground line and the Residual current protection line sent high frequency. This is in the receiving section modulated frequency again demodulated, and the demodulated computer data are then forwarded to the receiving computer.

Ein weiteres, ebenfalls nicht dargestelltes Beispiel der Erfindung ist eine Vorrichtung, die durch "Multiplexverfahren" einen gleichzeitigen Rechnerdatenaustausch möglich macht.Another example of the invention, also not shown, is a device which makes a simultaneous exchange of computer data possible by "multiplexing".

Eine ebenfalls nicht dargestellte Vorrichtung, als Zusatz zur Erfindung, kann die Übertragungsgrenzen, gegeben durch Fehlerstromsicherungsbereiche auf mehrere Fehlerstromsicherungsbereiche dadurch erweitern, daß die Rechnerdaten, die in einen Fehlerstromschutzbereich gesendet werden an einer Stelle, wo dieser Fehlerstromschutzbereich an einen anderen Fehlerstromschutzbereich grenzt, empfangen, verstärkt und in den anderen Fehlerstromschutzbereich gesendet werden. Auch hier ist eine Trennung der Fehlerstromschutzbereiche durch optoelektronische Koppelemente von Vorteil, da die Fehlerstromschutzbereiche dadurch vollständig unabhängig voneinander bleiben.A device, also not shown, as an addition to the invention, can Transmission limits given by residual current protection areas to several Extend residual current protection areas in that the computer data, which in one Residual current protection area are sent at a point where this Residual current protection area borders on another residual current protection area, received, amplified and sent to the other residual current protection area. Here is one too Separation of the residual current protection areas by optoelectronic coupling elements from Advantage because the residual current protection areas are completely independent of each other stay.
