Definitions

  • the invention relates to a method for monitoring and for operating a radio link between the outstations and the central unit of an alarm system after Preamble of claim 1.
  • the data telegrams must be in a certain Time interval between the central unit and the Signaling units are exchanged for malfunctions on the To be able to recognize radio link. Through this additional Exchanging the data telegrams becomes additional energy consumed. Since the signaling units with battery, rechargeable battery or Solar energy must be operated in order not to Can lose advantage of wireless installation the additional burden of regular Data telegrams significantly increase battery life shorten or, in the case of solar power supply, a require more powerful solar cells.
  • the invention is therefore based on the object caused by the exchange of data telegrams additional energy consumption to a minimum reduce the reliability of the alarm system is at least preserved or improved.
  • the Central unit or the outstations for example Monitoring sensors, the field strength in the for the Alarm system available radio channels supervised. Depending on the occurrence of non-operational Field strengths are then the time intervals for the Exchange of data telegrams changed.
  • interference field strengths can be caused by other devices that work in the microwave range, or they are generated with the intention of disrupting the radio alarm system.
  • a data telegram exchange is initiated more frequently than in normal operation. In normal operation, ie if no interference field strength is detected, a data telegram exchange is initiated, for example, every 20-30 seconds. In interference mode, ie when an interference field strength is detected, the data telegram exchange takes place, for example, every 4-5 seconds. The association of property insurers is currently stipulating a data telegram exchange every 10 seconds.
  • the energy consumption can be reduced by a factor of 2.5 by means of the safety queries, without accepting any restrictions in the operational safety of the alarm system have to.
  • the Data telegrams not only information about the Security of the radio link included, but if at the same time information about the functionality of the reporting units are transmitted. So through that Data telegram, for example, the functionality of the Sensors or the transmitter / receiver units are monitored will. In this way, the data telegrams can also used to check the functionality, whereby the energy consumption remains low, because there is no separate exchange of information.
  • This configuration of the invention makes it possible to only change the batteries or the accumulator when the There is a need for this.
  • the user of the Alarm system is no longer forced, as a precaution Exchange the energy storage to make without specifically there is a need to avoid that Signaling units due to a lack of power supply fail.
  • Another embodiment of the invention provides that in the event of an interruption in the data telegram exchange for a predetermined time alarm is triggered. This measure ensures that for example in the event of a failure of monitoring sensors the alarm is activated by disassembly or destruction becomes.
