PROCEDE DE TRANSMISSION SUR ONDE COMMUNE ET SYSTEME DE TRANSMISSION SUR ONDE COMMUNE ASSOCIE

摘要

Previously known common-frequency transmission methods and common-frequency transmission systems generally require complex devices for synchronizing and defining the route when a connection is established, especially so as to prevent loss of synchronism during operation and allow reconfiguration within the network in case of disturbances. In order to ensure fast and secure transmission of a message even when highly dynamic changes occur in the transmission paths, the transmit data in the common-frequency radio system or common-frequency wired transmission system is supplemented by a block identification, and the obtained transmission signal is emitted by the initiating common-frequency transmitter. A control unit (CU) that is connected to a block-recognizing device (BE) is provided at the receiving end in all subsequent synchronized transmitters in order to evaluate the block identification and control synchronization of the blocks and renewed transmission of the received data in synchronous common-frequency mode according to said evaluation. The invention applies to the field of common-frequency data transmission systems.
