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. Time stamps of successive raw measurement data are generated in the sensor on the basis of the 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.

A method operates a supply system having a measuring unit and a central unit. Information is transferred repeatedly at specific time intervals via a communication network by radio between the central unit and the measuring unit. The measuring unit or the central unit receives the information and then generates a receipt confirmation, which it transmits to the central unit or the measuring unit respectively.

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.

Abrégé

A method provides communication between a meter and a flying device. The meter records consumption data. The flying device performs flight movements to a prescribed target position of the meter. Radio signals are received by a reception device and information is ascertained, relating to the transmission quality of a radio channel, based on the received signals. A poor transmission quality, satisfaction of which is dependent on the quality of the information, results in the reception of received signals and the ascertainment of the information being repeated after a communication protocol for communication with the meter has been changed, a position of the flying device being altered and/or a directivity of the reception device is altered until the transmission quality or a termination condition is satisfied. Upon having a satisfactory quality condition, meter information is captured and a message for controlling the operation of the meter is sent to the meter.

To optimally receive smart meter control messages transmitted by a concentrator, in a meter having a transceiver for bidirectional data interchange, despite its minimal resources, a current modulation reference frequency which is subject to drift is shifted by the instantaneous frequency difference between the current transmitter-side reference frequency and the current transceiver-side reference frequency in the concentrator. Therefore, the current reference frequencies correspond in the downlink without having to intervene in the meter. This frequency difference in the concentrator is obtained by comparing the current receiver-side demodulation reference frequency with the current transmitter-side reference frequency, and the current transceiver-side reference frequency, on the other hand, from messages from the transmitter of the concentrator and from the transceiver of the meter which are received using the receiver of the concentrator. A frequency-measuring comparator only needs to be connected upstream and downstream of the demodulator in the concentrator for this purpose.

The invention relates to a method for communication between at least one meter device (1, 2, 3, 16) and an airborne device (4, 20, 22, 34, 39), wherein the meter device (1, 2, 3, 16) is designed to detect consumption and/or to collect detected consumption data, wherein the airborne device (4, 20, 22, 34, 39) carries out the following steps: f) the airborne device (4, 20, 22, 34, 39) capable of flight moves to a predefined target position (6, 17, 36, 41) associated with the meter device (1, 2, 3, 16); g) incoming signals are received by a receiver device (24) of the airborne device (4, 20, 22, 34, 39) on a radio-frequency channel assigned to the meter device (1, 2, 3, 16), and at least one item of quality information relating to a communication quality on the radio-frequency channel is determined in accordance with the incoming signals, wherein, if a quality condition, the fulfilment of which depends on the item of quality information, is not met, the reception of the incoming signals and the determination of the item of quality information are repeated after a communication protocol for communication with the meter device (1, 2, 3, 16) has been changed and/or while a position (12, 14) of the airborne device (4, 20, 22) and/or a directional characteristic (18) of the receiver device (24) are changed until the quality condition or a termination condition is met; and, if the quality condition is met, h) at least one item of meter information sent by the meter device (1, 2, 3, 16) is detected by evaluating the incoming signals and/or a control message for controlling the operation of the meter device (1, 2, 3, 16) is sent to the meter device (1, 2, 3, 16).

Abrégé

The aim of the invention is to achieve optimal receipt of the smart meter control telegrams (15) transmitted by a concentrator (data collector 12) in the case of a measuring device (11) having a transceiver (13) for bidirectional data exchange despite the minimal resources of said measuring device. This aim is achieved in that the current modulation reference frequency (f17) in the data collector (12), which modulation reference frequency is subject to drift, is shifted by the instantaneous frequency difference (Δf) between the current transmitter-side reference frequency (f17) and the current transceiver-side reference frequency (f13). Thus, the current reference frequencies (f17 = f13) match in the case of the downlink without intervention in the measuring device (11) being required. Said frequency difference (Δf) in the data collector (12) is obtained from a comparison of the current receiver-side demodulation reference frequency (f16) with the current transmitter-side reference frequency (f17) and with the current transceiver-side reference frequency (f13) from telegrams (14, 21) from the transmitter (17) of the data collector (12) and from the transceiver (13) of the measuring device (11), which are received by means of the receiver (16) of the data collector (12). Without demand for the resources of the measuring device (11), all that is required therefor is merely the connection of a frequency-measuring comparator (20) before and after the demodulator (24) in the data collector (12), followed by a frequency subtractor (22) connected to the transmitter-side conditioner (19.17) in order to derive the reference frequency (f) from an oscillator frequency (F).

In a bidirectional wireless data transmission system meter transmitters and concentrators communicate in wireless uplink and downlink connections. In order to be able to receive measured value data messages more reliably from the meter transmitters, the quality of wireless uplink connections which can be better received is reduced. This is done in that the concentrator acts with control signals via wireless downlink connections on parameters, such as transmitting power or message management, of the control of uplink transmitters. For this, uplink quality criteria automatically retrievable in the concentrator are, in particular, absolute or relative levels, signal-to-noise ratio and a relative number of receivable data messages.
