Data Transmission Arrangement, Data Receiver, and Method for the Operation Thereof

摘要

A data transmission arrangement includes an energy supplier for supplying the data transmission arrangement with electrical energy; a determiner for determining useful data provided by a sensor element connected to the data transmission arrangement; a coder for channel coding of the useful data so as to obtain channel-coded data; a splitter for splitting up the channel-coded data into a plurality of data packets having a code rate smaller than one; and a transmitter for transmitting data packets which is configured to transmit the plurality of data packets via a communication channel with a time lag, provided that an amount of electrical energy that can be provided by the energy supplier is sufficient for transmitting the respective data packets at a standard transmitting power.

1. A data transmission arrangement comprising:
an energy supplier for supplying the data transmission arrangement with electrical energy; a determiner for determining useful data provided by a sensor element connected to the data transmission arrangement; a coder for channel coding of the useful data so as to acquire channel-coded data; a splitter for splitting up the channel-coded data into a plurality of data packets comprising a code rate smaller than one; and a transmitter for transmitting data packets which is configured to transmit the plurality of data packets via a communication channel with a time lag, provided that an amount of electrical energy that can be provided by the energy supplier is sufficient for transmitting the respective data packets at a standard transmitting power, so that there are non-transmission periods in between the data packets during which no transmission is performed; the energy supplier comprising an energy harvesting element for non-line-conducted energy extraction from the environment of the data transmission arrangement; the energy supplier comprising an energy store for storing the energy extracted by the energy harvesting element, the energy store being configured for short, pulse-like load; the transmitter for transmitting data packets being configured to select the time lag with which the data packets are transmitted such that the energy store of the energy supplier is subjected to a short, pulse-like load; the transmitter for transmitting data packets being configured to either
transmit a data packet, which is about to be transmitted, of the plurality of data packets at a reduced transmitting power if an amount of electrical energy that can be provided by the energy supplier is sufficient for transmitting the respective data packet at the reduced transmitting power, the reduced transmitting power being reduced by a maximum of 40 dB as compared to the standard transmitting power; ornot transmit or to transmit with delay a data packet, which is about to be transmitted, of the plurality of data packets if an amount of electrical energy that can be provided by the energy supplier is not sufficient for transmitting the respective data packet.
