Definitions

  • the invention relates to a method for radio transmission in a hazard detection system with a main station and several slave stations, the main station and the slave station each have a transmitting and receiving device.
  • the hazard detection systems include signaling sensors as secondary stations, the one in the event of a detected danger (fire, burglary) Hazard notification via a radio link to a control center or main station (which also includes repeaters should transmit) in the further to eliminate the danger Measures (alerting the fire department or the police) be initiated.
  • the signal sensors each include a transmitting and receiving device and are intended for use self-sufficient in inadequate places, i.e. with a Battery operated.
  • EP 0 911 775 is a hazard detection system and a method for radio transmission in such a system known which is bidirectional and its components are designed to save energy. Disorders in one Such systems can be safely recognized in less than 100 s fading holes lead to unnecessary Fault messages.
  • a partial solution is achieved by increasing the sensitivity Recipient. This reduces the likelihood of interference but never disappears completely. That leaves In large systems in particular, there is always a certain probability of failure.
  • a radio controlled signaling and receiving system is also known from DE 296 01 436 U1.
  • the directional characteristic of at least one the antennas changed.
  • Another easy to implement method according to claim 5 is that at the location of the recipient and or the transmitter is switched to another antenna, which according to claim 6 by more than half the wavelength of the original antenna staggered, according to claim 7 by a different orientation than the original one Antenna or according to claim 8 by a compared to the first Antenna rotated polarization direction is marked.
  • the slave station can then via the other slave station report to the main station that this - the main station not reaching - slave station still functional and from the main station via the other slave station can be achieved.
  • the slave station sends its data for so long over the further secondary station to the main station, as long the direct connection to the main station is disturbed.
  • a detour can not only be done once, but continuously use for communication between main and secondary station.
  • An additional change in the spreading conditions between sender and receiver can be according to the procedure the advantageous embodiment of the method according to claim 14 achieve by changing the frequency of transmission becomes. This changes the ways of the waves a little and these are interfered differently. A variation within the 2 MHz wide SRD band (868 MHz to 870 MHz) is sufficient to move the phase by more than 10 ° to push.
  • FIG. 1 shows how a main station N, for example the headquarters of a hazard detection system or a Repeater, communicates with a secondary station S1.
  • the substation S1 can, for example, intrusion or fire alarm sensors include.
  • the main station M and the slave stations S1 each have transmit and not shown Receiving devices based on wireless communication initially between the main station M and the secondary stations S1 guarantee.
  • the secondary station S1 has a first Antenna 1 has another antenna 3, which is referred to in FIG Example spatially offset and perpendicular to the first antenna 1 is arranged.
  • the additional antenna 3 to be switched which will then communicate with the antenna 2 of the main station M enables.
  • additional antenna can also be arranged at the main station M. and by means of an appropriate control, the respective Antennas assigned to stations not only alternately, but also operated at the same time, which makes the Allow dispersion conditions to be changed even more flexibly.
  • FIG. 2 it is shown that in an arrangement with a main station M and a total of four secondary stations S1, S2, S3 and S4 the communication between the main station M and the secondary station S1 is disturbed, which is shown schematically in FIG. 2 through a dotted connection between the secondary station S1 and the main station M is shown.
  • the secondary station S1 sends its data to the further secondary station S2 and this transmits the data of the secondary station S1 then to the main station M.
  • the main station M can thus via the detour via the other secondary station S2 with the not accessible secondary station S1 communicate and exchange data.
  • the secondary station S1 is therefore in the main station M. not marked as disturbed.
  • the number can be significantly reduce the number of fault reports.
  • FIG. 3 shows how the secondary station S1 and the Main station M does not communicate with each other via a first frequency F1 can communicate, which in turn by the dotted line is shown while communicating via a second Frequency S2 is easily possible.
  • a frequency change can be provided, for example, when the communication is disturbed with the first frequency S1, but it can also a continuous frequency change at predetermined time intervals be provided.
  • the detour circuit via another substation, the change the antennas and the frequency change can now do so combined that if one of the ways doesn't work, one of the others is automatically applied.
  • the communication between the main station and the slave station disturbed differently can be.
  • the main station receives in the frame the integrity check at the given time none Signal from the slave, then try the master and slave communicate with each other on a different frequency. If communication via frequency change is unsuccessful, then the main station can communicate through the diversion trigger via the additional slave station.
  • the main station receives the signal received from the slave station for integrity checking and sends your acknowledgment signal, which is not from the secondary station Will be received.
  • the substation try to reach the main station in another way while the main station assumes communication be properly completed.
  • there is a Extra time slot is provided in which a slave station that has not received an acknowledgment signal and no other communication could set up a telegram with the main station transmitted to the main station. This receives this Telegram in the time slot provided for this, thus learns that the integrity check was not completed and can initiate additional measures, such as communication via another secondary station.
