Abstract: A method and a device are used during battery operation of a smart metering meter equipped with a consumption sensor and a transmit clock generator for a radio module for transmitting consumption data packets, in the event of a decreased residual capacity of the battery, to determine if the data packets can be transmitted as previously with the residual capacity over the residual time period until a scheduled battery exchange at the end of a specified operating time period. If not, the transmit power, for example, of the data packets is reduced and/or their transmit clock is extended over the residual period. This determination, along with a control specification, are preferably performed in a concentrator and are transmitted to the meter by using bidirectionally operating radio modules so that computer capacities required therefor need not be retained in each individual meter of a supply area.

Abstract: A method collects data, a physical or physico-chemical parameter and/or an operating state, during operation of a sensor. The sensor contains a measuring element which provides elementary measuring units, which correspond to a physical or physico-chemical variable or the physical or physico-chemical parameter, as raw measurement data, and the sensor has a communication device and a memory. To determine the measurement resolution of the sensor, the conditions for generating time stamps are first determined using a correlation model.

The time stamps are transmitted with the result that the raw measurement data acquired by the measuring element are reconstructed and evaluated based on the time stamps using the correlation model. Wherein operating state monitoring of the sensor is carried out by comparing current time stamps with historical and/or empirical time stamps.

Abstract: Domestic data are transmitted in the form of data messages from a data source to a memory in an unsynchronized manner in time slots via a freely accessible and accordingly heavily used transmission channel. On account of the interfering influences on the long data messages which occur in this case, the transmission of the data messages must be repeated several times until a data message is received without interference once. A comparator is used to determine a packet error rate from the ratio of the number of data messages received without interference over a certain period to the number of data messages actually transmitted during the period. A predefined packet error rate can be adaptively complied with despite varying transmission circumstances by varying the repeated transmissions per unit time.
