  • providing a detection signal means providing a non-zero detection signal; which means that a validated opening event has been detected; i.e. emit or transmit a detection signal.

  • the first duration D1 is adjustable analog or digital. It is for example between 1 second and 10 minutes. It is for example of the order of 1 minute, so that any opening event preceded by a presence detection in the previous minute will be deactivated and will not generate any detection signal.

  • this third variant if the person passes into the detection zone of the volumetric sensor (inhibition device 22) while moving away from it, this presence detection will not be considered, and a opening event which would be detected would be considered relevant to generate a detection signal and an alert. Furthermore, preferably, the removal of the person has the effect of canceling the previous approach, so that the alarm sensor 20 remains active even if the person inside the room approaches and moves away. of the sensor.

  • the cancellation device 24 then automatically adjusts the cancellation distance to a value less than all the recorded rest distances.
  • the cancellation distance is for example set to a value of 20% below the minimum rest distance.
  • the cancellation device 24 will eventually regularly delete the oldest rest distances. For example, any rest distance recorded for more than 2 weeks or more than 1 month will be deleted.
  • the cancellation device 24 is capable of automatically reducing and increasing the cancellation distance, that is to say automatically adapting the cancellation distance.
  • the cancellation device may also identify different rest distances for each wireless electronic device, and therefore a cancellation distance for each wireless electronic device.
  • the cancellation distance can be limited to a minimum value, minimum cancellation distance to guarantee sufficiently effective detection of the cancellation device 24.
  • the minimum cancellation distance is 1 meter.
  • a wireless electronic device in connection with the cancellation device 24 of the alarm sensor 20 or the central cancellation device 34 of the alarm center 30 may pose a problem if the user leaves this electronic device without wire near the alarm sensor or the alarm control panel, in a zone called cancellation zone, for example at a distance less than the cancellation distance.
  • the cancellation device 24 would be systematically activated, which systematically deactivates the detection signal, which permanently deactivates the alarm sensor and/or the alarm center and cancels all protection.
  • the cancellation distance is a parameter of the alarm sensor 20 and/or the alarm center 30.
  • the fourth duration is for example 10 minutes, which means that the wireless electronic device is installed for a long time.
  • the cancellation device 24, 34 can vary the analysis period.
  • the analysis period can be set to a first value, for example short, for example 2 minutes, then after a predetermined number of analyses, the analysis period can be set to a second value greater than the first value, for example 10 minutes.
  • the cancellation device 2 4 observes more precisely the presence of the wireless electronic device after the opening event, which corresponds to a moment when the wireless electronic device moves.
  • the infrared detector 222 is composed of two detection elements 222a, 222b comprising a pyroelectric material sensitive to the infrared optical domain.
  • the difference made between a first signal coming from the first detection element 222a and a second signal coming from the second detection element 222b is for example made by the processing electronics 223 which then provides the movement signal.
  • the first plane P1 is defined by the points A, D, E
  • the second plane P2 is defined by the points A, B, C.
  • the first plane P1 is positioned substantially parallel to the ground or the floor of the room (i.e. horizontal) relative to the ground
  • the second plane P2 is positioned substantially perpendicular to the ground (i.e. vertical).
  • the inhibition device 22 is a volumetric sensor placed as usual, that is to say with its first plane P1 substantially parallel to the floor of the room, and its second plane P2 substantially perpendicular to the ground.
  • the inhibition device 22 is a volumetric sensor 220 placed with its first plane P1 (moreover high density motion detection) substantially perpendicular to the floor of the room, for example at plus or minus 20° relative to a perpendicular to the floor.
  • this first plane P1 is substantially vertical.
  • its second plane P2 is usually perpendicular to the first plane P1.
  • the second plane is substantially horizontal (with the same angular range).
  • the inhibition device 22 is more sensitive to detect a person who is approaching or moving away from said inhibition device 22.
  • the inhibition device 22 can be directed towards the interior handle 4 of the opening 1 or towards an area close to said handle 4.
  • the direction D of the volumetric sensor 22 is defined by the intersection of the first plane P1 and the second plane P2, and therefore corresponds to an orientation of its infrared detector 222 and its optical system 221.
  • the inhibition device 22 detects the hand of the person approaching the interior handle 4 of the opening 1.
  • the volumetric sensor 220 has for example in the latter case a first opening angle a1 in the first plane P1 less than 60°, and for example less than 45°, and possibly less than 20°.
  • the volumetric sensor 220 has for example a second opening angle a2 in the second plane P2 greater than 90°, and for example 120° or more.
  • This second opening angle a2 of the second plane P2 is therefore widened compared to known sensors, which allows detection over a large width of the handle and the opening 1.
  • this volumetric sensor 220 has reversed characteristics or use compared to known volumetric sensors.
  • This volumetric sensor 220 effectively detects the movement of a person or the hand of a person who approaches or moves away from the opening 1 or the handle 4 of the opening.
  • the detection zone is better targeted.
  • the false detection rate is greatly reduced.
  • the volumetric sensor 220 of the second variant further comprises a wall 224 positioned substantially perpendicular to the infrared detector 222, between the two detection elements 22a, 22b.
  • This wall extends over a separation height moving away from said infrared detector 222.
  • the wall 224 is for example a sheet of metal or plastic. This wall has a spatial masking effect for infrared rays.
  • the first signal will have a temporal variation before the second signal, when the hand passes, and the difference of the first and second signals will have a greater variation, which increases the sensitivity of the volumetric sensor 222 in the first plane P1.
  • the volumetric sensor will not include an optical system such as lenses, these lenses being replaced by the simple wall.
  • the inhibition device thus produced will be more sensitive, more compact, more aesthetic and less expensive than known sensors.
  • the alarm system 10 is permanently active, which avoids forgetting to activate it when leaving the premises.
  • the alarm sensor 20 and/or the alarm center 30 include deactivation means to carry out this temporary activation/deactivation.
  • This action does not require identification of the person, as long as this action is carried out outside of any entry into the premises, i.e. carried out at a time not following such an entry.
  • This means of deactivation can be a button.
  • this deactivation means is supplemented by an alert means which warns the user(s) that the alarm sensor 20 and/or the alarm center 30 is inactive, and that the premises are not protected.
  • This alert means may be a visual indication (e.g. an LED) or an audible indication or an alert transmitted on the wireless electronic device(s) or an alert transmitted on one or more mobile telephones. Possibly, indications and/or alerts are regularly issued.
