Title: METHOD FOR DATA TRANSMISSION OF CONSUMPTION MEASURING DEVICES
Abstract:
Method for data transmission, more particularly for acquiring consumption data from consumption measuring devices (1), the method comprising a plurality of consumption measuring devices (1), each equipped with a communication module (2), and comprising a data collector (3) which is preferably fixedly installed, for receiving data packets (4) from the consumption measuring devices (1). During the transmission operation, the data packets (4) are sent via radio from each communication module (2) to the data collector (3) at defined time intervals within a defined sampling time period (10), wherein the data collector (3) has a control device (5) for temporally controlling a receiving operation, the control device (5) being designed to receive consecutive data packets (4) in a temporal sequence. The data collector (3) generates a time reference signal (6), by means of which each communication module (2) can determine when the sampling time period (10) begins, the time reference signal (6) is sent via radio from the data collector (3) to the relevant communication module (2) and the temporal sequence for transmitting the data packets (4) from each communication module (2) to the data collector (3) is adjusted in accordance with the time reference signal (6).
