Definitions

  • the invention relates to all types of alarm, security and monitoring systems, but in particular (partially) mobile systems. State of the art and criticism of the state of the art:
  • Video cameras ultrasound detectors, infrared detectors, electromagnetic field detectors that work in the microwave range, field barriers e.g. IB.
  • Photoelectric sensors capacitive detectors, structure-borne sound detectors, field circuits, glass break sensors, reed and double reed contacts, etc. These detectors are always autonomous, i.e. each individual detector is used as a single unit.
  • the invention is based on the object, the known susceptibility to interference, such as Reduce failures, false alarms, sabotage options etc. in alarm security and monitoring systems (especially the partially mobile) or switch them off completely.
  • This object is moderately achieved in that a multi-channel system with lateral inhibition and / or all-or-nothing circuit logic AND circuit or a chain of logic AND circuits and mutually monitoring a ⁇ is set. This is essentially achieved through a combination of known systems.
  • Sensor side At least two sensors of different types of operation, which are to monitor the same fuse field, are to be monitored here with regard to the alarm detector with lateral inhibition and / or all-or-nothing switching, i.e. e.g. be linked in a logical AND circuit or a chain of logical AND circuits.
  • this logic quiescent circuit essentially corresponds to an electrical parallel circuit.
  • the quiescent current circuit should of course be refined as possible to a differential current circuit.
  • each gate creation device in the case of the lateral inhibition
  • each logical AND circuit in the case of the all or nothing circuit
  • a coincidence protection and a mutual short-term storage.
  • this signal holding circuit must of course operate for a limited time.
  • a fault in the differential current also one
  • each signal path can be connected to a non-gate, the output of which is connected to an OR gate, the output of which is connected to a separate alarm device.
  • the alarm system can also be designed in any known manner. The invention can therefore be largely modified or used. An alarm system according to the invention can be provided in addition to burglar protection, for example for monitoring machines or production systems or even regulation.
  • the alarm transmission via the power network and / or radio is now available.
  • This multi-channel process is of course particularly interesting for semi-mobile systems, ie in particular a combination of signal transmission via the power grid and via radio.

  • RemanenzSclien safety circuit for example as residual current circuit
  • aif 'of the input side of the control panel can of the optical network to be perceived directly by the center itself of course also a failure, without that this requires confirmation by the detector itself.
  • a possible power failure at the alarm transmitter is also reported to the control center via the power supply itself by the absence of the idle current impulses, (ie the message via radio forms (only) an increase in redundancy or alarm confirmation.) This must now be confirmed via the network , for example by sensor-induced sensor alarm or by Strcm supply failure-induced sensor alarm or by sabotage-induced power transmission alarm, (see above) etc.
  • Detectors, control panels, transmitters, effector boxes are equipped with structure-borne sound detectors to prevent sabotage. Activation of these separate circuits, through which the body alarm is carried out, is delayed in order to avoid false alarms due to authorized operation (e.g. general alarm circuit, loop sharpening). Switching at the control center) Separate circles mean a special (partially) separate message transmission system (apart from operational current and radio frequencies) as normal operation.
  • the input side of the control panel also has a logical AND circuit with coincidence circuit, i.e. the input side of the detector with regard to the sensors. e.g. reciprocal short-term memory.

  • an alarm is only triggered when lateral inhibition 'simultaneously' reports an alarm signal via both channels - unless there has already been a sabotage message that has already led to the alarm.
  • single-channel sebccage fuses are also provided here, in addition to the mutual channel interference avoidance.
