Anordnung zur Überwachung der Datenübertragung über LichtleiterArrangement for monitoring data transmission via fiber optics
Eei der Übertragung von Meß- oder anderen Daten haben sich in den letzten Jahren Übertragungsmethoden durchgesetzt, bei denen die Daten in digitalisierter Form übertragen werden. Von den verschiedenen digitalen Übertragr.ngsmethoden sei beispielsweise die sogenannte Puls-Code-Kodulation erwähnt. Einer der Vorteile, die maßgeblich zu der Bevorzugung von digitalen Übertragungsmethoden beigetragen haben, ist darin zu sehen, daß es die digitalen Übertragungsmethoden gestatten, die Richtigkeit der übertragenen Daten zu überwachen. Beispielsweise sind bei der Puls-Code-Modulation in jedem zu übertragenden Codewort einzelne Bits vorgesehen, die der Überwachung der Signale dienen. Diese leichte Überwachungsmöglichkeit wird allerdings mit einem gewissen Anteil der für die Übertragung zur Verfügung stehenden Bandbreite erkauft, anders ausgedrückt, wird für die Überwachung ein Teil der für die Übertragung der Daten zur Verfügung stehenden Zeit benötigt.For the transmission of measurement or other data, transmission methods have prevailed in recent years, in which the data is transmitted in digitized form. Of the various digital transmission methods be for example the so-called pulse code coding mentioned. One of the advantages that have contributed significantly to the preference for digital transmission methods, can be seen in the fact that the digital transmission methods allow the correctness of the transmitted data to monitor. For example, in the case of pulse code modulation Individual bits are provided in each code word to be transmitted, which are used to monitor the signals. These easy monitoring is possible with a A certain proportion of the bandwidth available for transmission is bought, in other words, for the Monitoring part of the time available for the transfer of the data is required.
Neuerdings w?rden nun auch für die Datenübertragung Lichtleiter in Erwägung gezogen. Ausgehend von der Erkenntnis, daß die in Lichtleitern übertragenen Daten keinen Einstreuungen von außerhalb des Übertragungsweges unterliegen, insbesondere keinen Einstreuungen magnetischer oder elektrischer Natur, liegt der Erfindung die Aufgabe zugrunde, eine Anordnung zur Überwachung der Datenübertragung über Lichtleiter zu schaffen, die sehr einfacher Natur ist und keine Einschränkungen der für die Übertragung zur Verfügung stehenden Bandbreite verursacht. Gemäß der Erfindung ist eine derartige Anordnung dadurch gekennzeich-Recently, optical fibers have also been used for data transmission considered. Based on the knowledge that the data transmitted in optical fibers does not have any interference from outside the transmission path, in particular no magnetic or interference electrical nature, the invention is based on the object of an arrangement for monitoring the data transmission via fiber optics, which is very simple in nature and has no restrictions on the transmission available bandwidth. According to the Invention, such an arrangement is characterized

net, daß der oder die datenübertragenden Lichtleiter von mindestens einem einen von zwei möglichen Dauerzuständen (Iv1Il nrier dunkel) führenden Lichtleiter begleitet sind und an einem Ende der Übertragungsstrecke der begleitende Lichtleiter auf den Dauerzustand überwacht ist. Wird der datenübertragende Lichtleiter bzw. das Lichtleiterbündel durch einen äußeren Einfluß beschädigt, so wird der in dem begleitenden Lichtleiter auftretende Dauerzustand gestört und diese Störung festgestellt.net that the data-transmitting light guide (s ) are accompanied by at least one light guide leading one of two possible permanent states (Iv 1 Il nrier dark) and the accompanying light guide is monitored for the permanent state at one end of the transmission path. If the data-transmitting light guide or the light guide bundle is damaged by an external influence, the permanent state occurring in the accompanying light guide is disturbed and this disturbance is detected.
Zweckmäßig können die datenübertragenden Lichtleiter von einer Gruppe einen Dauerzustand führenden Lichtleitern begleitet sein. Es können auch zwei Gruppen je einen verschiedenen Dauerzustand führenden Lichtleiter die datenübertragenden Lichtleiter begleiten. Eine der Gruppen kann beispielsweise mit Dauerlicht gespeist werden, die andere kann dunkel belassen werden. Dabei ist es zweckmäßig, die Einspeisung des Lichts mit einer gemeinsamen Lichtquelle für die eine Gruppe von Lichtleitern vorzunehmen, ebenso kann die Gruppe der dunkel belassenen Lichtleiter mit einem gemeinsamen Empfänger auf Lichteinfall kontrolliert werden.The data-transmitting light guides from a group can expediently carry a permanent state light guides be accompanied. There can also be two groups, each with a different steady state leading optical fiber that transmits data Accompany light guides. For example, one of the groups can be fed with permanent light, the other can be left dark. It is useful to feed the light with a common light source for the one group of light guides, as well as the group of the light guides left dark with one common receivers can be checked for incidence of light.
Die überwachenden und einen Dauerzustand führenden Lichtleiter werden zweckmäßig in einer Außenlage des datenübertragenden Lichtleiterbündels angeordnet. Es ist jedoch auch daran zu denken, die überwachenden Lichtleiter gleichmäßig über den Querschnitt eines datenübertragenden Lichtleiterbündels zu verteilen.The monitoring and a steady state leading light guides are expediently in an outer layer of the data-transmitting Arranged light guide bundle. However, it should also be remembered that the monitoring light guides are uniform to be distributed over the cross section of a data-transmitting fiber optic bundle.
Sowohl der Sender für die zu übertragenden digitalen Daten als auch der Sender für die Überwachungslichtleiter kann aus einer Gruppe von Lichtquellen, wie beispielsweise Ga-As-Dioden, bestehen. Die Sender selbst können dadurch kontrolliert worden, daß ein Teil des ausgesandten Lichtes a;c 3nnd'.?ort selb '· wieder empfangen und ausgewertet wird.Both the transmitter for the digital data to be transmitted and the transmitter for the monitoring light guide can from a group of light sources, such as Ga-As diodes, exist. The transmitters themselves can be controlled by a part of the emitted light a; c 3nnd '.? ort selb' · is received and evaluated again.

Durch zusätzliche Lichtquellen auf der Empfängerseite, die im allgemeinen aus Fotodioden "bestehen kann, kann auch die Punktion des Empfängers sicher kontrolliert werden. By additional light sources on the receiver side, which can generally consist of "photodiodes", can the puncture of the recipient can also be safely checked.
Die Erfindung wird anhand zweier Figuren, die ein AusfUhrungsbeispiel in schematischer Darstellung zeigen, näher erläutert.The invention is based on two figures that illustrate an exemplary embodiment show in a schematic representation, in more detail explained.
In Figur 1 werden in einem Meßwertumformer M anfallende elektrische Daten in einem nachgeschalteten Sender S in digital verschlüsselte Lichtimpulse umgewandelt, die über ein Lichtleiterbündel Lb an einen Empfänger E übertragen werden.In Figure 1 are occurring in a transducer M electrical data in a downstream transmitter S converted into digitally encrypted light pulses that are transmitted via a light guide bundle Lb can be transmitted to a receiver E.
Figur 2 zeigt einen Querschnitt durch das Lichtleiterbündel Lb. In der Außenlage des Bündels sind einzelne geschnittene Lichtleiter zu erkennen, die abwechselnd durch eine bzw. keine Schraffur als dauerlichtführend oder dunkel belassen gekennzeichnet sind. Die dauerlichtführenden Überwachungslichtleiter in der Außenlage sine" beispielsweise im Sender zusammengefaßt und werden von einer Dauerlichtguelle gespeist. Auf der Empfängerseite ist jeder Lichtleiter des Bündels mit einer Fotodiode verbunden, die bei Ausfall einer Lichteinstrahlung ein Alarmsignal auslöst. Die dunkel belassenen Lichtleiter sind beispielsweise auf der Empfängerseite zusammengefaßt und dort optisch an eine einzige Fotodiode angeschlossen. Wird durch eine Beschädigung des Lichtleiterbündels einer der dunkel belassenen Lichtleiter von Außenlicht bestrahlt, so gibt die auf der Empfängerseite liegende Diode ein Alarmsignal.Figure 2 shows a cross section through the light guide bundle Lb. In the outer layer of the bundle are individual cut Light guides can be recognized, which alternate with a hatching or no hatching as permanently light-guiding or dark left are marked. The permanent lights Monitoring light guides in the outer layer sine "for example combined in the transmitter and fed by a continuous light source. Every light guide is on the receiver side of the bundle is connected to a photodiode, which triggers an alarm signal in the event of a loss of light. the Light guides that have been left dark are combined, for example, on the receiver side and are optically connected to one there only photodiode connected. If the fiber optic bundle is damaged, it becomes one of the dark ones If the light guide is exposed to outside light, the diode on the receiver side emits an alarm signal.
