Abstract

A transmitting and receiving part (SE), which is built into the PC, is continuously fed via a power supply device (SV), whereas the actual PC is fed via a switch (S) which can be controlled by the transmitting and receiving part (SE). <IMAGE>

Description

Die Erfindung betrifft eine Schaltungsanordnung zur Stromversor­ gung eines einen eingebauten Sende- und Empfangsteil zur Daten­ übertragung aufweisenden Personal-Computers.The invention relates to a circuit arrangement for the power supplier a built-in transmitting and receiving part for data transmission personal computers.

Im Zuge der modernen Datenverarbeitung tritt immer häufiger der Wunsch auf, das Personal-Computer untereinander kommunizieren können, z. B. mittels einer digitalen Nebenstellenanlage. Zu diesem Zwecke werden die Personal-Computer mit einem zusätzli­ chen Sende- und Empfangsteil ausgerüstet. Dabei tritt nun das Problem auf, das der Personal-Computer im ausgeschalteten Zu­ stand nicht empfangsbereit ist. Das heißt, daß der Personal- Computer, um immer empfangsbereit zu sein auch immer einge­ schaltet sein muß. Dies ist aus mehreren Gründen, z. B. Über­ hitzung, Verschleiß, Kosten ungünstig.In the course of modern data processing, the Desire to communicate with the personal computer can, e.g. B. by means of a digital private branch exchange. To For this purpose, the personal computer with an additional Chen transmitting and receiving part equipped. This now occurs Problem with the personal computer turned off was not ready to receive. This means that the personnel Computer always on to be ready to receive must be switched. This is for several reasons, e.g. B. About heating, wear, costs unfavorable.

Aufgabe der vorliegenden Erfindung ist es, eine Schaltungsan­ ordnung der eingangs genannten Art anzugeben, die eine unnötige Stromversorgung des Personal-Computers vermeidet.The object of the present invention is a circuit order of the type mentioned, which is an unnecessary Avoids power supply to the personal computer.

Diese Aufgabe wird erfindungsgemäß für eine Schaltungsanord­ nung der eingangs genannten Art dadurch gelöst, daß die Strom­ versorgung über ein externes Stromversorgungsgerät erfolgt, wobei die Stromversorgung des Sende- und Empfangsteiles konti­ nuierlich erfolgt, während die Stromversorgung des übrigen Personal-Computers über einen vom Sende- und Empfangsteil steuerbaren Schalter erfolgt.This object is achieved according to the invention for a circuit arrangement Solution of the type mentioned solved in that the current supply via an external power supply device, whereby the power supply of the transmitting and receiving part is continuous Nuclear, while the rest of the power supply Personal computer via one of the transmitting and receiving part controllable switch is done.

Mit Hilfe der erfindungsgemäßen Schaltungsanordnung wird eine unnötige Stromversorgung des Personal-Computers verhindert, während die Empfangsbereitschaft zu jeder Zeit gesichert ist.With the help of the circuit arrangement according to the invention prevents unnecessary power supply to the personal computer, while reception is guaranteed at all times.

Nachfolgend wird die erfindungsgemäße Schaltungsanordnung anhand eines in der Zeichnung prinzipiell dargestellten Aus­ führungsbeispiels näher erläutert.The circuit arrangement according to the invention is described below based on a principle shown in the drawing  management example explained in more detail.

In der Figur ist ein Personal-Computer PC mit einem Sende- und Empfangsteil SE dargestellt. Die Stromversorgung des Personal- Computers PC und des Sende- und Empfangsteiles SE erfolgt über das Stromversorgungsgerät SV. Dieses ist über die Leitung E mit dem Stromversorgungsnetz verbunden. Die Stromversorgung des Sende- und Empfangsteiles SE erfolgt über die Leitung L 1, während die Stromversorgung des übrigen Personal-Computers PC über die Leitung L 2 erfolgt. In der Leitung L 2 ist im Stromver­ sorgungsgerät SV ein Schalter S vorgesehen, welcher fernge­ steuert werden kann.In the figure, a personal computer PC is shown with a transmitting and receiving part SE. The power supply of the personal computer PC and of the transmitting and receiving part SE takes place via the power supply device SV. This is connected to the power supply network via line E. The power supply of the transmitting and receiving part SE takes place via line L 1 , while the power supply of the rest of the personal computer PC takes place via line L 2 . In the line L 2 in the Stromver supply device SV a switch S is provided, which can be controlled fernge.

Die Fernsteuerung des Schalters S erfolgt über die Leitung L 3, die den Sende- und Empfangsteil SE mit dem Stromversorgungsge­ rät SV verbindet.The remote control of the switch S takes place via the line L 3 , which advises the transmitting and receiving part SE to the Stromversorgungsge SV.

Für den Fall, daß der Personal-Computer nicht benutzt wird, erfolgt über die Leitung L 2 keine Stromversorgung des Computers, während über die Leitung L 1 eine kontinuierliche Stromversor­ gung des Sende- und Empfangsteiles SE erfolgt. Treffen nun unter diesen Bedingungen im Sende- und Empfangsteil SE Daten ein, so gibt die Sende- und Empfangsvorrichtung SE über die Leitung L 3 dem Stromversorgungsgerät SV den Befehl über die Leitung L 2 den übrigen Personal-Computer zu speisen, so daß die zu empfangenden Daten in einem entsprechenden Speicher abge­ speichert werden können. Nach Beendigung der Datenübertragung kann die Stromversorgung des übrigen Personal-Computers PC beendet werden.In the event that the personal computer is not used, there is no power supply to the computer via line L 2 , while a continuous power supply of the transmitting and receiving part SE takes place via line L 1 . If data now arrives in the transmitting and receiving section SE under these conditions, the transmitting and receiving device SE gives the power supply device SV the command via line L 3 to feed the rest of the personal computer via line L 2 , so that those to be received Data can be stored in an appropriate memory. After the data transmission has ended, the power supply to the remaining personal computer PC can be terminated.
