Abstract

In einem Funk-Gefahrenmeldesystem mit einer Zentrale (Z) und einer Mehrzahl von bidirektionalen (BT1 bis BT5) und unidirektionalen (UT1, UT2) Teilnehmern, versuchen die unidirektionalen Teilnehmer (UT1, UT2) Meldungen über einen der bidirektionalen Teilnehmer (BT1 bis BT5) an die Zentrale (Z) zu übermitteln. Dabei wird die von einem unidirektionalen Teilnehmer (UT2) gesendete Meldung von allen bidirektionalen Teilnehmern (BT1, BT2, BT5) in seiner Funkreichweite empfangen. Jeder bidirektionale Teilnehmer, der diese Nachricht empfangen hat, wartet bis zu einem ihm individuell zugeteilten Zeitschlitz, um die Nachricht weiterzuleiten. Während der Wartezeit überwacht jeder dieser bidirektionalen Teilnehmer (BT1, BT2, BT5) den Funkkanal, ob ein anderer bereits die Nachricht weitergegeben hat. Wenn dies der Fall ist, unterdrückt er seine eigene Weiterleitung.In a radio alarm system with a control center (Z) and a plurality of bidirectional (BT1 to BT5) and unidirectional (UT1, UT2) participants, try the unidirectional Subscriber (UT1, UT2) Messages via one of the bidirectional Subscriber (BT1 to BT5) to the control center (Z) to transfer. It is the one by a unidirectional participant (UT2) sent message from all bidirectional Participants (BT1, BT2, BT5) within its radio range. Each bidirectional participant receiving this message has received, waits for a person individually assigned to him Time slot to forward the message. During the Waiting time monitors each of these bidirectional subscribers (BT1, BT2, BT5) the radio channel, whether another already the Message has passed. If this is the case, suppressed he his own forwarding.

Auf diese Weise wird sichergestellt, dass nur einer der bidirektionalen Teilnehmer (BT1) die Nachricht weiterleitet, so dass keine Überlastung des Funksystems eintritt.

Figure 00000001
In this way it is ensured that only one of the bidirectional subscribers (BT1) forwards the message, so that no overloading of the radio system occurs.
