Abstract

Unter Ausnutzung freier Umschaltekontakte (ka1-kd1, ka2-kd2) wird eine stromsparende optische Anzeige dadurch erreicht, daß mehrere Umschaltekoppelpunkte (uk1-uk4) zusammengefaßt werden, und in dem Fall, daß alle Umschaltekoppelpunkte (uk1-uk4) gleichzeitig aktiviert sind, eine einzelne gemeinsame Anzeige über ein Relais (GES) erfolgt.Using free switchover contacts (ka1-kd1, ka2-kd2), a power-saving visual display is achieved in that several switchover coupling points (uk1-uk4) are combined, and in the event that all switchover coupling points (uk1-uk4) are activated at the same time, one individual joint display via a relay (GES).

Description

Dadurch, daß bei der erfindungsgemäßen Schaltungsanordnung jeweils mehrere Koppelpunkte, z. B. vier Koppelpunkte, zusammengefaßt werden, und bei, Aktivierung aller dieser Koppelpunkte dann nur eine optische Anzeige erfolgt kann der Stromverbrauch für die optische Signalisierung erheblich verringert werden, ohne daß auf die Eindeutigkeit der Anzeige verzichtet werden muß. Das bedeutet zum einen eine verringerte Dimensionierung der Strornversorgungsbaugruppen und damit Platzersparnis, und zum anderen eine Vermeidung einer zu großen Wärmeentwicklung und der durch diese entstehenden Probleme.The fact that in the circuit arrangement according to the invention each have several coupling points, for. B. four Crosspoints, are combined, and when all these crosspoints are activated, only one optical one Display takes place, the power consumption for optical signaling can be significantly reduced, without having to forego the uniqueness of the display. On the one hand, this means a reduced Dimensioning of the power supply modules and thus space savings and, on the other hand, avoidance too much heat and the problems caused by it.

Die Erfindung wird im folgenden anhand eines in einer Zeichnung dargestellten Ausführungsbeispieles beschrieben. Es zeigtThe invention is described below with reference to an embodiment shown in a drawing. It shows

F i g. 1 den prinzipiellen Aufbau einer Umschalteeinrichtung, welche z. B. eingehende Leitungen sowohl mit einer Betriebsanlage als auch mit einer Notanlage verbinden kann,F i g. 1 the basic structure of a switching device, which z. B. connect incoming lines to both an operating system and an emergency system can,

Fig. 2 die prinzipielle Anordnung der gemäß der Erfindung vorgesehenen zusätzlichen Kontakte zur stromsparenden optischen Signalisierung des Schaltzustandes der einzelnen Umschaltekoppelpunkte.Fig. 2 shows the basic arrangement of the according to Invention provided additional contacts for power-saving optical signaling of the switching state of the individual switchover crosspoints.

In Fig. 1 ist eine Betriebsanlage AnIi und eine Notanlage AnI2 dargestellt, die jeweils über eine Umschalteeinrichtung UMSmildem Leitungssystem L verbunden werden können. Dabei wird davon ausgegangen, daß über das Leitungssystem L Informationen einlaufen und Informationen von der jeweils angeschalteten Anlage ausgesendet werden. Von der Umschalteeinrichtung L/MS ist nur ein Umschaltekoppelpunkt dargestellt, bestehend aus den R/-Kontakten uk 1 bis ukA, wobei im dargestellten Beispiel angenommen ist, daß es sich bei dem Leitungssystem L um eine 4-Draht-Leitung handelt. Weiterhin ist eine der Umschalteeinrichtung UMSzugehörige Steuerung St dargestellt, die aufgrund ihr eingegebener Informationen (Ausfall der Anlage AnIi, prüfen) die einzelnen Umschaltekoppelpunkte aktiviert, d. h. z. B. die Umschaltekontakte uk 1 bis uk 4 betätigt und damit die Notanlage an das Leitungssystem L schaltet.1 shows an operating system AnIi and an emergency system AnI2 , which can each be connected to the line system L via a switching device UMSmildem . It is assumed that information is received via the line system L and information is sent out by the system that is connected in each case. From the switchover device L / MS only one switchover coupling point is shown, consisting of the R / contacts uk 1 to ukA, it being assumed in the example shown that the line system L is a 4-wire line. Furthermore, a control St belonging to the switchover device UMS is shown, which activates the individual switchover coupling points based on the information it has entered (failure of the system AnIi, check), i.e., for example, actuates the switchover contacts uk 1 to uk 4 and thus switches the emergency system to the line system L.

Im dargestellten Ausführungsbeispiel wurde von einer 4-Draht-Leitung ausgegangen, denkbar ist aber auch ein andersartig aufgebautes Leitungssystem. Hinzu kommt, daß, wie schon ausgeführt wurde, Umschalteeinrichtungen auch zum Umschalten von Leitungen eingesetzt werden. Hieraus ergibt sich, daß eine Umschalteeinrichtung möglichst universell eingesetzt werden soll, daß pro Umschaltekoppelpunkt ein oder mehrere Relais mit einer Anzahl von zu beschaltenden Kontakten eingesetzt werden, welche je nach Beschallung universell einsetzbar sind und damit von ihrer Beschaltungsmöglichkeit her in den meisten Fällen überdimensioniert sind.In the exemplary embodiment shown, a 4-wire line was assumed, but this is conceivable also a differently structured pipe system. In addition, as has already been stated, switching devices can also be used to switch lines. It follows that a switching device to be used as universally as possible that one or more switching points per switchover coupling point Relays with a number of contacts to be wired are used, which depends on the sound are universally applicable and thus of their wiring options are oversized in most cases.

In Fig.2 sind die pro Koppelpunkt neben den die eigentliche Umschaltung vornehmenden Umschaltekontakten uk 1 bis uJt 4 die zusätzlich vorgesehenen Kontakte ka 1 bis kd\ und ka 2 bis kd2 dargestellt. Bei dieser Darstellung sind z. B. die Kontakte ka 1 und ka 2 einem bestimmten Koppelpunkt zugeordnet, ebenso z. B. die Kontakte kd 1 und kd 2.In FIG. 2, in addition to the switchover contacts uk 1 to uJt 4 that perform the actual switchover, the additionally provided contacts ka 1 to kd 1 and ka 2 to kd2 are shown for each coupling point. In this representation, for. B. the contacts ka 1 and ka 2 assigned to a certain coupling point, as well as z. B. contacts kd 1 and kd 2.

Dabei ist jeweils einer der zusätzlichen Kontakte, nämlich die Kontakte kai bis kdi, jeweils mit einer Leuchtdiode LD1 bis LD 4 in Reihe geschaltet. Die jeweils zweiten der zusätzlichen Kontakte, die Kontakte ka 2 bis kd2, sind mit einem Gesamtrelais GESin Reihe geschaltet.One of the additional contacts, namely the contacts kai to kdi, is connected in series with a light-emitting diode LD 1 to LD 4. The second of the additional contacts, the contacts ka 2 to kd2, are connected in series with an overall relay GES.

Bei dem in F i g. 2 dargestellten Ausführungsbeispiel ist davon ausgegangen, daß jeweils vier ICoppelpunkte zusammengefaßt sind. Aus der Darstellung ergibt sich eindeutig, daß wenn einer oder mehrere der vier Koppelpunkte geschaltet werden, die entsprechenden Leuchtdioden LD Ϊ bis LD 4 aufleuchten. Sind alle vic-r Koppelpunkte geschaltet, so wird über die zweiten zusätzlichen Kontakte ka 2 bis kd 2 das Gesamtrelais GFS erregt. Dadurch wird mit Hilfe des F//-Kontaktes ges des Gesamtrelais CES Spannung an eine gemeinsame Leuchtdiode LDg gelegt, die dann aufleuchtet, während die Stromversorgung für die übrigen Leuchtdioden LD1 bis LD 4 unterbrochen wird. Sind also alle vier zu einer Gruppe zusammengefaßten Umschaltekoppelpunkte geschaltet, so leuchtet nur eine einzelne Leuchtdiode. Zur besseren Erkennung kann dabei die Farbe der gemeinsamen Leuchtdiode eine andere sein als die der einzelnen Leuchtdioden LD1 bis LD 4.In the case of the FIG. 2 is based on the assumption that four crosspoints are combined. The illustration clearly shows that when one or more of the four coupling points are switched, the corresponding light-emitting diodes LD Ϊ to LD 4 light up. If all vic-r coupling points are switched, the overall relay GFS is excited via the second additional contacts ka 2 to kd 2. As a result, with the help of the F // contact ges of the general relay CES, voltage is applied to a common light-emitting diode LDg, which then lights up while the power supply for the other light-emitting diodes LD 1 to LD 4 is interrupted. If all four changeover coupling points combined to form a group are switched, only a single light-emitting diode lights up. For better recognition, the color of the common light-emitting diode can be different from that of the individual light-emitting diodes LD 1 to LD 4.

Im in F i g. 2 dargestellten Ausführungsbeispiel sind als zusätzliche Kontakte normale Arbeitskontakte dargestellt, denkbar ist jedoch, daß statt dessen auch FU-Kontakte verwendet werden können.In FIG. 2, normal working contacts are shown as additional contacts, but it is conceivable that frequency converter contacts can also be used instead.

In certain application cases, the failure of an entire system or larger parts of a system lead to an unacceptable security risk, e.g. B. in air traffic control technology, where many in-depth Information must be sent to specific addresses. In such applications, next to an emergency system is provided for the actual operating system, which fully takes over the tasks of the operating system can. In the event of failure of an entire system or parts of this system, a switching device takes care of it for switching from the operating system to the emergency system. Switching devices are also used for switching to other lines if the regular lines fail.

Such switching devices usually consist of several switching assemblies, each with several switchover coupling points, with the individual switchover assemblies as slide-in units in cabinets are summarized.
