Definitions

  • the invention relates to a railway installation with communication devices, in particular for cable routing, according to the preamble of claim 1.
  • railway systems with a rail network for rail vehicles are well known.
  • train management communication devices are used in the known railway systems, which are provided as route devices on the route and as vehicle equipment in the rail vehicle. With the help of the communication devices data is transmitted by means of high-frequency signals using frequency bands.
  • the frequencies of the high-frequency signals are typically in the range of 30 kHz to 148 kHz.
  • the object of the invention is to ensure the data transmission in a railway system with little effort.
  • the solution to the problem provides that a plurality of frequency bands are provided, that the data is transmitted as a data packet in succession, wherein at least one of the frequency bands is used to transmit a datum, and that another frequency band is used to transmit the next datum. It is technically simple if the frequency bands are used successively to transmit the data. This can be further simplified if the frequency bands for transmitting the data are cyclically changed according to a predetermined order.
  • Figure 1 belongs to a railway system, not shown, which comprises a travel route network for electric rail vehicles.
  • route devices track-side communication devices
  • vehicle devices vehicle-side communication devices
  • the route devices and the vehicle devices exchange data by means of high-frequency signals, with part of the data being used for the train guidance.
  • the high-frequency signals lie in predetermined frequency bands.
  • FIG. 1 shows a frequency-time diagram in which a plurality of frequency bands 1 (1a-1g) are provided which do not overlap expediently.
  • Each frequency band 1 can be used for data transmission, wherein the data transmission, however, takes place in such a way that exactly one of these frequency bands 1 is used for each data, in particular as a data packet.
  • the frequency bands for data transmission are available only for a limited period, that is to say a so-called time slot 2 (2a-2i).
  • the frequency band 1a in time slot 2a is used to transmit a first date.
  • the frequency band 1f is used in the time slot 2b for transmission of the next data to be transmitted, then the frequency band 1e in the time slot 2c for transmission of the third date, etc.
  • the data are thus transmitted one after the other, with one of the frequency bands 1 being used to transmit a single date.
  • the frequency band 1 (e.g., 1f) of the next-to-be-transmitted data is different from the immediately preceding frequency band 1 (e.g., 1a).
  • another frequency band 1 of the total frequency bands 1 (1a-1g) is used.
  • FIG. 2 corresponds to FIG. 1 except for a frequency range 3 in which a communication quality regarded as poor is present. This may for example be the case when the transmitted data is not transmitted, preferably within an immediately preceding period, which may for example comprise the length of 10 time slots 2.
  • FIG. 3 corresponds to FIG. 2, wherein in the frequency range with the poor communication quality there are no more available frequency bands for data transmission; H. the frequency bands 1e, 1f lying in this frequency range were excluded from the data exchange. This can also take place during the project planning of the railway installation, if at that time it is already clear in which spatial areas of the railway installation on certain frequency bands there will not be sufficient communication quality.
  • the quality of communication refers in each case to a quality criterion, e.g. that no data transmission is possible because of missing high-frequency signal.
