Abstract

A software defined radio type radio receiver is used in an environment that is self-sufficient in energy. The radio receiver has a receiving device, which receives the data in the form of a data packet or a portion thereof or a data stream at a certain data rate, and provides the data for further data processing. Wherein in an operating mode, the data is diverted at the receiving device and supplied to a microcontroller at a sampling rate which preferably can be defined. The microcontroller decimates the data by selecting a subset from the set of samples, and the microcontroller buffers in a memory and provides for further processing the decimated data.

Abstract

A method selects frequency channels in a communication system using a frequency hopping method, in which data are transmitted between a transmitter and a receiver. The data are transmitted as data packets having a plurality of bits in a frequency/time block. A respective data packet is coded before transmission by the transmitter and is decoded after reception by the receiver. The transmission quality of the frequency channels is evaluated and, a decision is made for a selection of the frequency channel which is used for the transmission of the data. A likelihood ratio for the likelihood of a successful transmission is determined before the decoding by the receiver, the likelihood ratio is used as a metric for determining the interference state of the respective data packet, and the transmission quality of the respective frequency channel is evaluated on the basis of the interference state of the data packet.

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. 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.

Abstract

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. The central unit or the measuring unit, after transmitting the information, opens a receive window of a certain time length for receiving the receipt confirmation. As a result of a first trigger event, the time intervals between the repeat transmissions of the information are shortened, and/or an additional receive window for receiving the receipt confirmation is opened, and as a result of a second trigger event, the time intervals between the repeat transmissions are lengthened, and/or no additional receive windows are opened.

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.

Abstract

A method selects frequency channels in a communication system using a frequency hopping method, in which data are transmitted between a transmitter and a receiver. The data are transmitted as data packets having a plurality of bits in a frequency/time block. A respective data packet is coded before transmission by the transmitter and is decoded after reception by the receiver. The transmission quality of the frequency channels is evaluated and, a decision is made for a selection of the frequency channel which is used for the transmission of the data. A likelihood ratio for the likelihood of a successful transmission is determined before the decoding by the receiver, the likelihood ratio is used as a metric for determining the interference state of the respective data packet, and the transmission quality of the respective frequency channel is evaluated on the basis of the interference state of the data packet.

Abstract

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.

Abstract

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.

Abstract

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).

Abstract

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.
