Derartige In­ stallationseinrichtungen, die induktiv mittels eines Wandlers angekoppelt sind, gehören zum Stand der Technik (EP 8 81 17 687.8).The invention relates to an installation device the building system technology, its subscriber stations to one Bus are coupled for information transfer and at the same time be supplied with energy for the electrical system. Such In installation devices inductively by means of a converter coupled are part of the prior art (EP 8 81 17 687.8).

Wird eine Alarmanlage über einen derartigen Bus betrieben, so ist eine Notstromversorgung, beispielsweise aus Akkumulatoren, bereitzustellen. Deren Kapazität ist in der Praxis so zu be­ messen, daß die Alarmanlage wenigstens 24 bis etwa 60 h ga­ rantiert weiterversorgt wird. Da die Teilnehmerstationen, deren Funktion zur Alarmanlage nicht beitragen, mit ihrem in der Re­ gel hohen Energieverbrauch die Notstromversorgung belasten, müßte die Versorgungskapazität wesentlich größer ausgelegt wer­ den. Dadurch entstehen ständige erhöhte Kosten.If an alarm system is operated via such a bus, then is an emergency power supply, for example from accumulators, to provide. Their capacity can be used in practice measure that the alarm system ga at least 24 to about 60 h is guaranteed further supply. Since the subscriber stations whose Do not contribute to the alarm system with its function in the re high energy consumption burden the emergency power supply, the supply capacity would have to be designed much larger the. This causes constant increased costs.

Der Wandler kommt auf der Information verarbeitenden Seite mit einer Wicklung aus. Die Wicklung auf der Energie bereitstellenden Seite ist mit einer Abschalteinrichtung verbunden. Diese spricht an, wenn ein vorgegebener Wert unterschritten wird. Bei einem Bus mit einer Versorgungspannung von 24 V kann bei Netzausfall und Unterschreiten einer Spannung von 15 V beispielsweise automa­ tisch abgeschaltet werden, so daß der Bus von den nicht bevor­ zugt betreibenden Teilnehmerstationen freigeschaltet wird.The converter can be constructed in particular according to claim 2 be. He works with at least one winding on the energy providing side, to which a capacitor is connected in series is switched, at its connections DC voltage for the Energy supply is provided. The converter comes up the information processing side with a winding. The winding on the energy supply side is included a shutdown device connected. This responds when a predetermined value is undershot. With a bus with a supply voltage of 24 V can occur in the event of a power failure and Falling below a voltage of 15 V, for example automa table be turned off so that the bus from the not before is activated operating subscriber stations.

Die Abschalteinrichtung kann vorteilhafterweise nach Patentan­ spruch 3 ausgeführt sein. Danach besteht die Abschalteinrich­ tung aus einem Ventil in Reihe zum Kondensator, das von einem Schwellwertschalter gesteuert wird, der zumindest die Spannung am Kondensator abgreift.The shutdown device can advantageously according to Patentan saying 3 be executed. Then there is the shutdown device tion from a valve in series to the condenser, which by a Threshold switch is controlled, at least the voltage tapped at the capacitor.

In einem einfachen Ausführungsbeispiel kann die Abschaltein­ richtung nach Patentanspruch 4 aus einem Transistor bestehen, dessen einer der Anschlüsse aus Emitter und Kollektor mit einer Wicklung des Wandlers auf der Energie bereitstellenden Seite verbunden ist und dessen anderer Anschluß mit den Kon­ densator verbunden ist. Zwischen Basis und dem Anschluß des Kondensators, mit dem der Transistor nicht verbunden ist, kann eine Zenerdiode mit Vorwiderstand parallel geschaltet sein.In a simple embodiment, the shutdown can direction according to claim 4 consist of a transistor, whose one of the connections from emitter and collector with a winding of the converter on the energy providing Side is connected and its other connection with the Kon capacitor is connected. Between the base and the connection of the Capacitor to which the transistor is not connected a Zener diode with a series resistor can be connected in parallel.

Dieser kann beispielsweise aus zwei antiparallel geschal­ teten Transistren, u-p-n- oder p-n-p-Transistoren, bestehen. Er kann auch aus zwei in Serie geschalteten Feldeffekttran­ sistoren gebildet sein. Durch den bipolaren Schalter wird sichergestellt, daß eine Wechselstromnachricht ungehindert die Abschalteinrichtung passieren kann.A subscriber station that is suitable for the installation facility suitable, has a shutdown device according to the invention  on that works at least with a bipolar switch.

Die Erfindung soll nun anhand eines in der Zeichnung grob sche­ matisch wiedergegebenen Ausführungsbeispiels näher erläutert werden:The invention is now based on a rough in the drawing cal matically reproduced embodiment explained in more detail will:

Die Installationseinrichtung nach Ausführungsbeispiel gemäß der Zeichnung weist an einem Bus 1 angeschlossene Teilnehmersta­ tionen 2 auf, von denen eine veranschaulicht ist. Über den Bus 1 wird Information und Energie für die Bordnetze übertragen. Einige der Teilnehmerstationen 2 sind derart bevorzugt betrie­ ben, daß ihr Betrieb bei Ausfall der Energieversorgung sicher­ gestellt ist. Die veranschaulichte Teilnehmerstation gehört zur Gattung der nicht bevorzugt zu betreibenden. Mittels eines Wandlers 3 wird Information induktiv in einen Informations­ zweig 4 übertragen und die Energie für das Bordnetz in einen Energiezweig 5 ausgekoppelt. Zur Pufferung der Energieversor­ gung ist eine Notstromversorgung 6 bereitgestellt. Der Wandler 3 weist eine Energie bereitstellende Seite 7 und eine Infor­ mation verarbeitende Seite 8 auf. Der Zweig des Wandlers auf der Energie bereitstellenden Seite 7 ist durch einen Konden­ sator 9, zum Schließen des Nachrichtenpfades, hinsichtlich des Energiepfades unterbrochen. Von der Unterbrechungsstelle gehen die Leiter des Energiezweiges 5 ab, um die Teilnehmerstation 2 mit Energie zu versorgen. Dieser Kondensator kann gleichzei­ tig zur Glättung oder als Energiespeicher für kurzzeitige Unterbrechung der Bordnetzversorgung dienen. The installation device according to the exemplary embodiment according to the drawing has subscriber stations 2 connected to a bus 1 , one of which is illustrated. Information and energy for the on-board networks are transmitted via bus 1 . Some of the subscriber stations 2 are preferably operated such that their operation is ensured in the event of a power failure. The subscriber station illustrated belongs to the category of those which are not to be operated with preference. By means of a converter 3 , information is transmitted inductively into an information branch 4 and the energy for the vehicle electrical system is coupled out into an energy branch 5 . An emergency power supply 6 is provided to buffer the energy supply. The converter 3 has an energy supply side 7 and an information processing side 8 . The branch of the converter on the energy supply side 7 is interrupted by a capacitor 9 , for closing the message path, with respect to the energy path. The conductors of the energy branch 5 depart from the interruption point in order to supply the subscriber station 2 with energy. This capacitor can simultaneously serve for smoothing or as an energy store for brief interruptions in the on-board electrical system supply.

Eine Teilnehmerstation 2 der wiedergegebenen Art gehört zur Gattung der Teilnehmerstationen, die bei Netzausfall der Bus-Versorgung nicht bevorzugt zu betreiben sind, sondern durch eine Abschalteinrichtung 10 vom Bus 1 bei Netzausfall abzuschalten sind.A subscriber station 2 of the type shown belongs to the category of subscriber stations which are not to be operated preferentially in the event of a power failure of the bus supply, but are to be switched off by the bus 1 in the event of a power failure by means of a disconnection device 10 .

Im Ausführungsbeispiel weist der Wandler 3 zwei Wicklungen 11 auf der Energie bereitstellenden Seite 7 auf. Der Kondensator 9 ist in Serie zu den Wicklungen 11 angeschlossen. An seinen Anschlüssen wird Gleichspannung für die Energieversorgung des Bordnetzes den Energiezweig 5 bereitgestellt. Auf der Informa­ tion verarbeitenden Seite 8 kommt der Wandler mit einer Wick­ lung 12 aus. Im Ausführungsbeispiel ist die obere Wicklung 11 auf der Energie bereitstellenden Seite 7 mit einer Abschalt­ einrichtung 10 verbunden.In the exemplary embodiment, the converter 3 has two windings 11 on the energy supply side 7 . The capacitor 9 is connected in series with the windings 11 . At its connections, DC voltage for the energy supply of the vehicle electrical system is provided to the energy branch 5 . On the information processing page 8 , the converter manages with a winding 12 . In the exemplary embodiment, the upper winding 11 on the energy-providing side 7 is connected to a shutdown device 10 .

Die Abschalteinrichtung 10 kann im Prinzip aus einem Ventil in Reihe zum Kondensator 9 bestehen. Dieses wird von einem Schwellwertschalter gesteuert, der zumindest die Spannung am Kondensator 9 abgreift.The shutdown device 10 can in principle consist of a valve in series with the capacitor 9 . This is controlled by a threshold switch, which at least taps off the voltage across the capacitor 9 .

Im Ausführungsbeispiel besteht die Abschalteinrichtung 10 aus einem Transistor 13, einem pnp-Transistor, dessen einer der Anschlüsse aus Emitter 14 und Kollektor 15 mit einer Wicklung 11, im Ausführungsbeispiel der oberen Wicklung, des Wandlers auf der Energie bereitstellenden Seite 7 verbunden ist. Im Aus­ führungsbeispiel ist dieser Anschluß der Emitter 14. Der an­ dere Anschluß, der Kollektor 15, ist mit dem Kondensator 9 ver­ bunden. Zwischen Basis 16 und dem Anschluß des Kondensators 9, mit dem der Transistor 13 nicht verbunden ist, ist eine Zener­ diode 17 mit Vorwiderstand 18 parallel geschaltet.In the exemplary embodiment, the shutdown device 10 consists of a transistor 13 , a pnp transistor, one of whose connections from the emitter 14 and collector 15 is connected to a winding 11 , in the exemplary embodiment the upper winding, of the converter on the energy-supplying side 7 . In the exemplary embodiment, this connection is the emitter 14 . At the other connection, the collector 15 , is connected to the capacitor 9 a related party. Between the base 16 and the connection of the capacitor 9 , to which the transistor 13 is not connected, a Zener diode 17 with a series resistor 18 is connected in parallel.

Wenn der Bus mit einer Versorgungsspannung von 24 V Gleichspan­ nung gespeist wird und die Gleichspannung größer als 15 V ist, wird der Transistor 13 über die Zenerdiode, beispielsweise eine "Z 15", aufgesteuert. Damit steht am Kondensator 9 die für die Teilnehmerstation 2 erforderliche Bordnetzspannung zur Ver­ fügung. Sinkt bei Ausfall der Speisespannung die Gleichspannung am Bus unter 15 V, wird der Transistor 13 gesperrt und dem Bus wird durch diese Teilnehmerstation und alle der Gattung der nicht bevorzugt zu betreibenden Teilnehmerstationen keine Ener­ gie entzogen.If the bus is supplied with a supply voltage of 24 V DC and the DC voltage is greater than 15 V, the transistor 13 is turned on via the Zener diode, for example a "Z 15". Thus, the on-board electrical system voltage required for the subscriber station 2 is available at the capacitor 9 . If the DC voltage on the bus drops below 15 V when the supply voltage fails, the transistor 13 is blocked and the bus is deprived of energy by this subscriber station and all of the type of subscriber stations which are not to be operated with preference.
