BEKANNTMACHUNG " DER ANMELDUNG UND AUSGABE DERNOTICE OF "REGISTRATION AND ISSUE OF THE
Für den kommerziellen Nachrichtenverkehr sind leitungsgebundene oder leitungsgerichtete Funkanlagen bekannt, über die mittels Hochfrequenztelefonie Mitteilungen übertragen werden können. Neuerdings wird für derartige Anlagen, insbesondere bei ihrem Einsatz im Bergbau unter Tage, gefordert, daß außer der Sprache besondere Signale, z. B. finden Notruf, gegeben werden können, und zwar derart, daß die rufende Stelle eine Rückmeldung erhält, daß das Signal auf der Gegenseite angekommen ist. Lösungen für diese Aufgabe sind noch nicht bekanntgeworden. Wired or wired radio systems are used for commercial communications known, over which messages can be transmitted by means of high-frequency telephony. Recently it has been required for such systems, especially when used in underground mining, that in addition to language, special signals, e.g. B. find an emergency call, can be given, in such a way, that the calling station receives feedback that the signal has arrived on the other side. Solutions for this task are not yet known.
Die Erfindung schlägt vor, zur Auslösung eines besonderen Signals in leitungsgebundenen oder leitungsgerichteten Funksprechanlagen mit Rückmeldung der erfolgten Auslösung an die rufende Stelle die Sendefrequenz der rufenden Funksprechstelle kurzzeitig, etwa durch eine zeitlich begrenzte Kontaktgabe, zu ändern und die Anlage auf »SendeVi« zu schälten und an der Kommandostelle parallel zum üblichen Empfänger einen auf die geänderte Frequenz abgestimmten selektiven Empfänger vorzusehen, dem ein Schaltmittel zugeordnet ist, das beim Ansprechen einerseits den Sender der Kommandostelle auf »Senden« schaltet, andererseits gleichzeitig ein akustisches Signal auslöst, dessen Ton über die normale Sendeanlage und Sendeleitung an die rufende Stelle zurückübertragen wird.The invention proposes to trigger a special signal in wired or wired radio intercom systems with feedback of the triggering to the calling station, to change the transmission frequency of the calling radio station briefly, for example by making contact for a limited time, and to switch the system to "SendeVi" and Provide a selective receiver tuned to the changed frequency at the command post parallel to the usual receiver, to which a switching means is assigned which, when responding, switches the command post's transmitter to "send" on the one hand, and on the other hand triggers an acoustic signal at the same time, the tone of which is transmitted via the normal transmitter system and transmit line is retransmitted to the calling station.
An Hand der Zeichnung sollen die Erfindung und ihre weiteren Einzelheiten näher erläutert werden:The invention and its further details are to be explained in more detail with reference to the drawing:
Mit Sl und El sind die Sende- bzw. Empfangseinrichtung der Kommandostelle bezeichnet, die über den Schalter ul wahlweise an die als Antenne wirkende Leitungsschleife v41 anschaltbar sind. S2, E2, A2, u2, S3, E3, A3, u3 bezeichnen die entsprechenden Einrichtungen der Funksprechstellen, von denen nur zwei Anlagen dargestellt sind. Die übliche Nachrichtenübermittlung findet in bekannter Weise statt: Die Antennenumschalter ul . . . sind normalerweise auf die Empfänger geschaltet; wird von einer Sprechstelle eine Mitteilung abgesetzt, so wird durch die Sprechtaste der entsprechende Schalter u auf den Sender umgelegt und die Nachricht vom MikrophonJWl, M2 oder M3 über den Sender auf die Antenne gegeben und von den Gegenstellen aufgenommen. Sl and El denote the transmitting and receiving devices of the command post, which can be optionally connected to the line loop v41 acting as an antenna via the switch ul. S2, E2, A2, u2, S3, E3, A3, u3 designate the corresponding devices of the radio communication stations, of which only two systems are shown. The usual transmission of messages takes place in a known manner: The antenna switch ul. . . are normally switched to the receivers; If a message is sent by a call station, the corresponding switch u is turned over to the transmitter by the push-to-talk button and the message is sent from the microphone, M2 or M 3 via the transmitter to the antenna and picked up by the remote stations.
Für einen Notruf von einer Sprechstelle zur Kommandostelle ist nun erfindungsgemäß an den Sprechstellen eine Notruftaste T2, T3 vorgesehen, die kurzzeitig einerseits die Umschaltung der Sprechstelle auf Senden bewirkt, andererseits die Frequenz des Sendeoszillators verändert. Diese Frequenzänderung ist durch die Darstellung eines Kondensators C am Sendeoszillator 0 2 bzw. 0 3 svmbolisch antje-Funksprechanlage für den leitungsgebundenen oder leitungsgerichteten NachrichtenverkehrFor an emergency call from a call station to the command post, an emergency call button T2, T3 is now provided according to the invention on the call stations, which on the one hand causes the call station to switch to transmission for a short time and on the other hand changes the frequency of the transmit oscillator. This frequency change is represented by a capacitor C on the transmitter oscillator 0 2 or 0 3 svmbolisch antje radio intercom system for wired or wired communications

deutet. Die kurzzeitige Kontaktgabe kann in bekannter Weise z. B. durch die Verwendung eines Wischkontaktes erfolgen. An der Kommandostelle liegt parallel zum Empfänger El ein Resonanzempfänger EAr (Notrufzusatz), der auf die Frequenz des kurzzeitig gesendeten Trägers abgestimmt ist. Bei Durchgabe eines Notrufsignals spricht der Empfänger EN an und erregt das Relais N, das über den Kontakt η den Notruf selbst als akustisches Signal einschaltet. Die Dauer des Notrufes ist unabhängig von der Dauer des auslösenden Trägers; er kann entweder manuell oder durch einstellbare zeitabhängige Schaltmittel abgeschaltet werden. Vom Relais N wird ferner der Antennenschalter u1 auf Senden umgelegt, so daß der Notruf vom Lautsprecher Ln über das Mikrophon M 1 und den Sender .91, auf den üblichen Träger aufmoduliert, auf die Antennenschleife^l gelangt. Von hier aus empfängt die den Notruf auslösende Sprechstelle den Ruf, da ihre Anlage kurz nach Abgabe des Notrufträgers auf Empfang zurückschaltet. Ebenso kann jede andere Funksprechstelle den Ruf aufnehmen, sofern sie nicht zufällig gerade selbst eine Nachricht sendet.indicates. The brief contact can be made in a known manner, for. B. be done by using a wiper contact. At the command post, parallel to the receiver El, there is a resonance receiver EA r (emergency call add-on), which is tuned to the frequency of the briefly transmitted carrier. When an emergency call signal is transmitted, the receiver EN responds and energizes the relay N, which switches on the emergency call itself as an acoustic signal via the contact η. The duration of the emergency call is independent of the duration of the initiating carrier; it can be switched off either manually or by adjustable time-dependent switching means. The relay N also switches the antenna switch u1 to transmit, so that the emergency call from the loudspeaker Ln via the microphone M 1 and the transmitter 91, modulated onto the usual carrier, reaches the antenna loop ^ l. From here the intercom initiating the emergency call receives the call, as its system switches back to receive shortly after the emergency call carrier has been handed over. Any other radio intercom can also pick up the call, as long as it does not happen to be sending a message itself.
Die Erfindung beschränkt sich nicht auf durch das Beispiel gegebene Anordnung, sondern kann selbstverständlich auch für andere bewegliche Funkverbin-The invention is not restricted to the arrangement given by the example, but can of course also for other mobile radio links
