Definitions

  • the invention relates to an alarm system with autonomous alarm sensors and alarm generators excited by the alarm sensors.
  • the object of the invention is to provide an alarm system which does not require a central device and whose alarm sensors which cannot be switched off can be set up at any time and in new distribution.
  • the alarm system according to the invention differs from the prior art in that all alarm sensors have equal rights.
  • Each alarm sensor responds with its sensor to a change in the environment to be monitored and gives when a change is detected an alarm signal.
  • an excitation signal is emitted to excite further alarm sensors.
  • all of the system's alarm sensors are excited and emit alarm signals.
  • the effect of an alarm sensor can thereby be multiplied.
  • the alarm sensors can be installed in any distribution without a fixed installation plan. This distribution can be changed at any time. It is therefore not possible for unauthorized persons to deactivate the alarm system. Once an alarm sensor is energized, it can no longer be switched off, possibly until the energy source is exhausted.
  • the individual sensors respond to changes in the environment in a manner known per se.
  • the sensors can respond to changes in position, changes in force, changes in lighting, shocks, influences of sound, accelerations. You can provide sensors of any kind in the individual alarm sensors.
  • a complete autonomous energy supply for each alarm sensor is achieved in that a battery is used as the energy source for each alarm sensor.
  • a particularly effective alarm is ensured in that the alarm transmitter emits an acoustic alarm signal itself.
  • An alarm system can comprise any number of alarm sensors.
  • 1 shows a system with four alarm sensors 1, 2, 3, 4, each of which is autonomous, that is to say independent of an external energy supply, and has equal rights with one another.
  • the sensor 7 responds to an environmental condition.
  • the sensor 7 can be position-dependent, force-dependent, acceleration-dependent. It can also respond to light signals, acoustic signals, impact sound and any other environmental signals caused by unauthorized intruders.
  • the alarm trigger circuit 9 is excited. This cannot be switched off after a single excitation.
  • the alarm trigger circuit turns on the excitation signal circuit 10, which outputs an excitation signal. It can be a high-frequency signal that is emitted via an antenna 13.
  • the signal can be encoded to prevent interference with other signal sources.
  • the antenna 13 is simultaneously the transmitting antenna and the receiving antenna.
  • the receiving part of the antenna 13 is connected to the receiving circuit.
  • the receiving circuit 8 responds to excitation signals from any other alarm sensor of the alarm system and also acts on the alarm trigger circuit 9. This ensures that all alarm sensors of the system are energized as soon as any alarm sensor is excited by an unauthorized influence.
  • the alarm trigger circuit 9 acts on an alarm transmitter 11, which generates an acoustic alarm signal, for example.
  • Each alarm sensor contains such an alarm device and can generate an acoustic alarm signal send out.
  • other alarm signals can also be provided.
  • the alarm signal from the alarm transmitter can also be transmitted to a stationary facility. In any case, it is important that each individual alarm sensor emits such an alarm signal. As a result, a large number of alarm signals are generated in accordance with the large number of alarm sensors, which lead to enormous confusion of the unauthorized intruder.
  • the whole system is triggered when any alarm sensor is excited.
  • This excitation state remains after a single excitation, since the receiving circuits are designed as latching circuits. So the excitement cannot be recalled.
  • the excitation can be ended after a predetermined time. In the simplest case, the excitation stops after the battery is exhausted.
