Abstract

Communication between a terminal, such as a consumption meter, installed at a fixed location and a mobile data collector, by way of Wireless M-Bus, via a short-range radio receiver. Data from the terminal is forwarded to the data collector via a bidirectional WPAN interface. The terminal sends a message periodically and unprompted for the communication set-up and subsequently opens a reception window after a period of time. In response, a command or a command sequence is conveyed from the mobile data collector to the receiver and to the terminal in one or more reception windows. The receiver determines the reception time at which the message arrives at the receiver, and the receiver stipulates the time at which the command or command sequence is transmitted onward to the terminal, so that the command or command sequence is received by the terminal within one reception window or multiple reception windows.

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

Data are transmitted by radio between a terminal and a data collector. The data collector is intermittently or constantly in receive mode. The terminal attempts, from an idle phase, to set up a communication with the data collector in order to send all or some of the data to the data collector and/or to receive them from the data collector. Alternatively, the data collector attempts to set up a communication with the terminal in order to send all or some of the data to the terminal and/or to receive them from the terminal. The setup of the communication is followed by the terminal sending a message to the data collector and the data collector, after receiving the message, continuing, interrupting and/or terminating the transmission of the data during communication on a basis of the content of the message.

The microprocessor encodes the data before transmission and/or decodes the data after reception, each using a computing cycle. When the electrical variable changes during the computing cycle, it is interrupted, preferably at any desired point. The encoding and/or decoding are carried out separately during the computing cycle in individual encoding phases in which the value of the electrical variable changes. Regeneration phases for regenerating the electrical variable are provided between and/or within the encoding phases. The duration of a regeneration phase is such that the value of the electrical variable approaches or reaches the initial value during the regeneration phase.

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 improves the transmission quality between a data collector and a plurality of metering units. A first communication module is assigned to the data collector and a second communication module is assigned in each case to a metering unit. The second communication module transmits data via radio signals to the first communication module. The first communication module has a first frequency reference device and the second communication module has a second frequency reference device. The radio signals transmitted are dependent on the second frequency reference device. The measurement of a parameter of the radio signal is performed by the first communication module. An estimation of an error of the second frequency reference device on the basis of the parameter measured values is determined. An adjustment of the frequency of the first frequency reference device is performed such that the error is reduced.

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

Mobile units moving in a local network environment and at times in the vicinity of meters of the network, at least temporarily bypass relay functions of a concentrator operated in a stationary manner, if the relay function is not yet available, for instance during construction, for radio communication of data packets of the meter linked into the smart-metering network to a center. The mobile units are persons and/or vehicles with communication devices such as smartphones for long-distance links over the Internet or in the mobile radio standard. The communication devices, as modified mobile radio telephones, receive data packets from meters by using hardware or a software app over a short-distance link to the mobile unit being accidentally temporarily located in the vicinity of the meter. Long-distance communication of packets from mobile unit to center then takes place over the Internet or the mobile radio standard.

Abstract

A control device for a meter device, particularly a water meter device, includes a first data interface for a meter unit measuring a flow of a fluid of the meter device, a second data interface for a reading device communicating with the meter unit through the control device, and a supply interface receiving a combined clock and voltage supply signal for the control device. The control device can assume a read mode in which data at the first data interface can be transmitted by the control device to the second data interface upon receiving a clock and voltage supply signal having a read signal variation. The control device can additionally assume a write mode in which data at the second data interface can be transmitted to the first data interface upon receiving a clock and voltage supply signal with a write signal variation different from the read signal variation.

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.
