Data transmission system, especially for obtaining utility data

摘要

Data packets (PA, PB, PC) are transmitted from respective transmitter (A,B,C) in time intervals (Xs) to the receiver (E), which has a time controller (S) for its operation, which is designed to estimate the expected next data transmission on the basis of rated value of the sequential time intervals. Thus the receiver is switched on for a tolerance interval (TA, TB, TC), containing the estimated time point. The controller corrects the respective actual rated value for time interval from last to next transmission by a specified factor. An independent claim is included for the receiver.
