Definitions

  • the invention relates to a method for sending a digitized message of low information depth such.
  • Transmitters of the generic type such as. B. radio sensors have to get by with a limited energy reserve available to them to do their job.
  • the energy required is divided into a proportion of useful energy that flows into the transmitted signal, and a proportion of loss of energy that is ultimately converted into z. B. unnecessary thermal energy is lost.
  • This object is achieved by a method for sending a digitized message of low information depth, such as.
  • the energy saving is due to the shortening of the transmission signal as a whole and thus the shortening of the time for the generation of
  • the method according to the invention can advantageously be expanded by repeatedly sending out the same data. This avoids or circumvents the influence of intermittent interferences.
  • a possible interference is the periodic signal of an energy supply network and a device connected to it, which for example oscillates at a frequency of 50 to 60 Hz and thus with a period of 16 to 20 milliseconds.
  • interference pulses of a periodic type are also taken into account when selecting the time interval between two transmission pulses.
  • These are e.g. B. the periodic transmission pulses caused by the frequency multiplexing of a mobile radio telephone with a time interval of approx. 125 ⁇ s. It is therefore advantageous to select the time intervals not equal to the 125 ⁇ s of a mobile radio network and not equal to the 16 to 20 ms of an energy supply network.
  • the time period between the transmission pulses is selected in a further advantageous embodiment such that it is of integer multiples of interference signal periods within a range the signal pulses are different.
  • the method according to the invention can advantageously be expanded in that the value of individual bits transmitted is increased by the fact that coding of the bits is not only two-valued, e.g. B. high or low, but is multi-valued. So it is z. B. possible to increase the multi-value of a bit by not carrying the information signal high or low, but the temporal occurrence of the voltage signal. It is thus possible to transmit multiple pieces of information with the same energy.
  • FIG. 1 shows a schematic representation of the energy flows
  • FIG. 2 shows a power-time diagram
  • FIG. 3 shows the temporal appearance of transmit and interference pulses
  • Figure 4 shows a more than two-valued transmission protocol.
  • FIG. 1 shows a schematic representation of the energy flows during a transmission process.
  • the energy 1 supplied to the transmitter 8 is divided into a useful energy 2 and a loss energy 3 during the transmission process.
  • the useful energy is transferred to the transmitted signal, the loss energy is usually unwanted and only heats up the transmitter and control electronics.
  • the power-time diagram in FIG. 2 shows the proportions of useful energy 2 and loss energy 3 with different bandwidths 9 and the resulting shorter or longer transmission times ti; t 2 .
  • the proportion of lost energy 3 compared to the useful energy 2 is significantly lower.
  • FIG. 2 thus shows that by increasing the bandwidth and the associated shortening of the transmission time while the power consumption of the circuit remains the same, the proportion of energy loss can be reduced.
  • the method allows redundant or repeated transmission events to increase transmission security.
  • These transmission events shown in a time diagram in FIG. 3 are selected in accordance with the method in such a way that the time interval 4 between two transmission events is either a fixed one Time interval or a randomly selected variable time interval.
  • FIG. 3 shows that in the event of a random overlay and thus interference with the first transmission event, the second transmission event is not already overlaid by another signal.
  • the decisive factor here is the selection of the time interval between the two transmission events. It makes sense and is advantageous to choose the distance between the two transmission events so that it differs from the period of known interference signals.
  • a randomly selected time interval 4 also has the advantage that the case in which two interference pulses are located at exactly the predetermined time interval 4 and thus interfere with a first and a second transmission event is due to the random choice of the time interval between two transmission pulses reduced. This is shown in FIG. 3 at the right end of the time axis t.
  • a time or position coding as shown here allows the information content of a single transmitted bit to be multiplied.
  • the signal sequence shown in FIG. 4 firstly shows an 1111 (hi-hi-hi-hi) signal sequence over a period of four pulses. This bit sequence thus represents an information content of 2. If the information of a single transmitted pulse is not available in the usual way of 1 or 0, but in the temporal appearance, a transmission of 4 2 information is possible in the same time but with half the energy requirement.
  • This information is therefore of higher value with a lower energy requirement than would be achievable in the same time of 4 cycles in the usual way, in the form of cycle-wise, two-valued hi-lo signals.

Abstract

L'invention concerne un procédé d'émission d'une information numérique de faible profondeur d'information telle que des valeurs de mesure de capteurs, à l'aide d'émetteurs, par exemple d'émetteurs radio, présentant des stocks d'énergie limités. Selon ledit procédé, les données sont émises par impulsions et chaque impulsion de données transmet les données à un débit supérieur à 100 Kbit par seconde. Pour optimiser davantage d'énergie avec ledit procédé, le contenu d'information d'une impulsion transmise individuellement est augmenté par codage de temps ou de position.
