Radio data transmission system for use in e.g. teleconnection system, has substations transmitting data telegrams to central station in transmitting period between two laterally separated data telegrams of central station

摘要

The system has a central station (ZS) with a host computer (LR), which determines transmitting time for data telegrams (AT11,AT12) of sub stations (U1,U2). The computer transmits the data telegram as a time target for the substations. The substations transmit the data telegrams to the central station in a transmitting period, which is determined by the host computer, between two laterally separated data telegrams of the central station.
