Definitions

  • the invention relates to a method for radio transmission in a danger reporting system according to the preamble of Patent claim 1.
  • Funk is a nearly ideal transmission medium for building technology. Devices with radio technology are quick to install and easy to adapt to changing requirements. The disadvantage, however, is the relatively short range in Buildings at carrier frequencies in the gigahertz range. Become used to increase the range so-called. Repeater requires the high energy consumption until today mains-powered devices. This is especially true for radio systems in the new SRD band between 868 and 870 MHz.
  • this List also includes a group membership.
  • a method with frequency change can be make it easier that a change of frequency channels according to an education law known to all participants he follows.
  • a particularly simple configuration method according to claim 8 provides that the participants themselves at the first Commissioning brought into a configuration mode in which the participants look for the other participants and include them in their lists as you find them. Thereby the configuration effort can be minimized.
  • the receiving devices of the participants cyclically switched on at predetermined times and willing to send Participants send preambles that are the address of the Participant to receive the preamble.
  • receives a receiving device one of the preambles, the addressed to this receiving device so remains the Receiving device turned on until the complete preamble was received and in the event that no preamble received was, the receiving device is switched off again.
  • the cycles are chosen so that the time interval, in which the receiving device is turned off, opposite the time interval in which the receiving device is switched on, by more than a factor of 5 is greater.
  • the receiving device changes in the switched-on State the frequency of the reception frequency to the currently in the US valid FCC rule for Frequency Hopping to fulfill.
  • the radio traffic can be further reduced according to claim 12, in the case of a desired Transmission to several intended for the reception Participants the preamble only once sent out and the associated Reception facilities remain switched on for as long as until the preamble was received.
  • Figure 1 is shown as a first participant 1 with a first transmitter 2 and a first receiver 3 equipped is, wherein the first participant 1 with a second participant 4 (which also has a second transmitter 5 and a second receiver 6) and with a third party 7 (with a third transmitter 8 and a third receiver 9) forms a hazard detection system.
  • the individual participants 1,4,7 may have, for example, additional sensors, for example, detect a fire hazard or as a motion detector detect a burglary attempt.
  • participants 1,4,7 can also central functions take over, for example, initiate an alarm or a Display the building view with the corresponding alarm locations. It is also conceivable that the individual participants 1,4,7 Actuators have to close doors, turn on light or to set blinds in motion.
  • the receiver checks regularly (for example every 300 ms), if a participant wishing to send is active is.
  • the settling time of the receiver must be so small be that the resulting average current is the batteries not burdened too much.
  • Settling times of less than 1 ms.
  • a participant willing to send now sends a preamble to it allows the recipient to recognize the request.
  • this preamble must be sent for 300 ms, to ensure that the intended for the reception Participant then turned on his receiver.
  • These Preamble does not necessarily have to be empty, it can For example, the entire data telegram is included.
  • Additional information in the preamble may be, for example indicate the start time of the actual telegram. The receiver is then until the beginning of the payload switched off again and thus can save electricity.
  • the preamble is sent out only once and the associated receivers are intended for reception Participants do not switch off immediately, but wait the exchange of the telegrams.
  • each subscriber keeps a list that gives information about which next participant (mediator) of this one any other Participants of the radio cell can reach.
  • a list is shown by way of example in FIG. 2a.
  • the participant shown in Figure 2a 7 attains participants 5,6 and 8 directly while the participants 1 to 4 on the participant 5, the participants 9 and 10 can be reached via the participant 6. It says the indication that the participant 2 about the participant 5 to reach is not that the participant 5 direct contact to the participant 2 has.
  • Another mediator can certainly be provided its like in the example list of the subscriber 5 is shown in FIG. 2b.
  • the first-time extraction goes without an additional tool. To do this go through the following steps: first becomes the first participant brought the radio cell into a configuration mode.
  • the participant searches for already existing participants in the Configuration Mode. Because the first participant no other such participant, this participant defines himself a cell number and waiting for other participants sign up with him.
  • the second participant of the radio cell is in the configuration mode brought. He finds the participant 1 and is called Number2 integrated into the system. Both now have one each Place in their list, as shown in Figure 3a for the Subscriber 1 and Figure 3b shown for the participant 2 is.
  • the third participant in the configuration mode brought. For example, if this only finds the Participant 2, but not the participant 1, he lets himself submit its list. So the third participant knows that he can reach the participant 1 via the participant 2. The participant 2 now transmits to the participant 1 that the Participant 3 can reach over him (the participant 2). The corresponding stored lists then correspond to the participant 1 of Figure 4a, for the participant 2 of the figure 4b and for the participant 3 of Figure 4c.
  • FIG. 5 shows that each subscriber of a radio cell be associated with one or more functional groups can.
  • These function groups are in further lines of the Lists shown, as shown in Figure 5 with the letters A, B. and C is shown.
  • Each participant, as shown, can belong simultaneously to several groups, as it is in Example of the participant 6, who at the same time the groups A and B are listening. With the help of such groups can, for example Lamp collectives are switched together.
