- FIG. 11 is a schematic side view of the embodiment of Figure 10.
- Figure 1 is a general view of the system of a first embodiment of an alarm system 10 according to the invention.
- This alarm system 10 comprises for example:
- an alarm sensor 20 for opening according to
- a central unit 30 including, for example in a housing, a display 31 and a central control panel 32, and
- a remote keypad 40 advantageously placed near an entrance door, corresponding to an opening 1 of a building room, and / or an external siren 41, one and the other being connected to the casing of the central unit 30 by a wired or wireless connection for greater ease and security.
- the opening 1 shown in Figure 1 is a door, but the opening could be a window.
- the opening 1 comprises a fixed portion 2 surrounding an opening and a movable portion 3 adapted to close or open said opening.
- This opening 1 (opening) is located between an interior space and an outer space of the room.
- the present alarm system therefore seeks to protect the premises from unwanted intrusions from outside.
- Figure 2 shows more precisely the alarm system 10 comprising the alarm sensor 20 for opening and the alarm center 30 according to a first embodiment of the invention.
- the alarm sensor 20 comprises:
- an opening sensor 21 which detects an opening event of the opening 1,
- an inhibition device 22 which detects the presence of a person in the interior space in the vicinity of the opening 1, and
- an electronic unit 23 connected to the opening sensor 21 and to the inhibition device 22 and which generates a detection signal.
- the opening sensor 21 is adapted to detect an opening event of the opening 1, that is to say the opening of the moving part 3. This opening event can be determined by the movement of the opening. moving part 3 with respect to the fixed part 2, or by only the movement of the movable part 3.
- the opening sensor 21 may comprise a single element connected to the mobile part 3 to measure its movement, that is to say its displacement, its speed or its acceleration.
- An accelerometer sensor or a gyro sensor can thus be used to detect this movement.
- the opening sensor 21 may comprise two elements 21a, 21b.
- the first element 21a is connected to the movable part 3 and the second element 21b is connected to the fixed part 2, as illustrated in FIGS. 1 and 2, or vice versa.
- the opening sensor 21 of this second variant is for example a magnetic sensor.
- a magnet is housed in the first element 21a and a sensor type sensor "Reed” or “Hall” effect sensor is housed in the second element 21b.
- a sensor type sensor “Reed” or “Hall” effect sensor is housed in the second element 21b.
- Such a “Reed” sensor well known, comprises flexible blades of magnetic material which magnetize by influence, and are attracted to each other in the presence of a magnetic field generated by the magnet. This sensor thus closes an electrical circuit when the first and second elements 21a, 21b are in close proximity to each other.
- the opening sensor 21 of this second variant is optionally an optical sensor, the first element 21a accommodating a reflector and the second element accommodating an optical-type transceiver, for example by infrared, as is also well known.
- the opening sensors 21 according to this second variant have the advantage of reliably detecting the closed state or the open state of the opening 1.
- the alarm system 10 can thus be automatically and systematically activated as soon as the Closed state is detected.
- the opening sensor 21 combines:
- a motion sensor (measurement of displacement, speed or acceleration), such as an accelerometer, and
- a position sensor (measurement of the closed position), such as a proximity magnetic sensor mentioned above or such as a magnetic terrestrial field sensor.
- the opening event is defined by:
- an opening event is validated if the intermediate position of the opening exceeds a first threshold, and a closing event is enabled if the intermediate position of the opening is less than a second threshold, which corresponds to a hysteresis function which is reset by the complete closed position detected by the position sensor.
- the inhibition device 22 is adapted to at least determine the presence of a person in the interior space near the opening 1.
- the inhibition device 22 is a simple push button, the person having to press on said push button before each opening event of the opening 1, to signal its presence inside, and therefore signal in advance that the opening event of the opening 1 will correspond to an opening action performed from inside the premises, and therefore that this opening event is performed by an authorized person and not by an intruder.
- the inhibition device 22 is a volumetric sensor making it possible to detect a movement in a detection zone (volume) opposite said volumetric sensor.
- This volumetric sensor often called a pyroelectric sensor, usually comprises an optical system that divides the detection zone alternately into active and inactive zones, an infrared detector (adapted to the infrared range) that provides a motion signal, and a processing electronics that detects variations in this signal, and thus a movement of a person (infrared emitter) in the detection zone.
- the inhibition device 22 directly and autonomously detects the presence of a person in the detection zone by the movement of said person.
- the detection zone is then advantageously adjusted to detect a portion of the interior space near the opening 1. For example, the detection zone will cover a projected portion of 2x2 m (ground) in front of this opening 1.
- the device Inhibition 22 then has an inhibition distance of 2 meters below which the detection will have the effect of avoiding the emission of the detection signal by the electronic unit 23.
- the inhibition device 22 is a volumetric sensor making it possible to detect a movement in a detection zone (volume), only if said movement is a movement that is close to the motion sensor device.
- the processing electronics detects not only the variations in the motion signal, but also determines:
- the variations correspond to a signal from a person who approaches the volumetric sensor, i.e. person from the interior of the premises, and corresponding to a person a priori authorized; or
- the variations correspond to a signal of a person moving away from the volumetric sensor, ie person coming from outside the room, especially if there has been no reciprocal forward movement, and therefore corresponding to an unauthorized person (intruder).
- the electronic unit 23 will provide the detection signal only if the presence detected by the muting device corresponds to a movement away from said person of said muting device.
- the inhibition device 22 is a camera which detects a movement in a detection zone (portion of the image), by a treatment of the temporally successive images (for example by correlation between said successive image portions ).
- the inhibition device 22 is a proximity sensor which detects a mere presence in the vicinity, that is to say at a short distance, for example less than 50 centimeters.
- This proximity sensor is for example an infrared sensor, or a light emitting diode (LED) transmitter type transmit / receive advantageously placed near the handle.
- LED light emitting diode
- the electronic unit 23 is connected to the opening sensor 21 and the muting device 22, receives their respective signals (opening event and presence of a person, respectively), and providing a detection signal:
- Providing a detection signal means providing a non-zero detection signal; which means that a validated open event has been detected; that is, transmit or transmit a detection signal. It is the known operation of the alarm sensors that provide a detection signal after the detection of an event, and which do not provide if no event is detected. These detectors, usually wireless type and self-powered by a battery or battery, thus save energy.
- the first duration D1 is adjustable analogically or numerically. 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 disabled and generate no detection signal.
- the alarm sensor 20 takes into account the opening event detected by the opening sensor 21 only if no presence has been detected by the inhibition device 22 during the first duration Dl preceding the opening event.
- this third variant if the person passes in the detection zone of the volumetric sensor (inhibition device 22) away from it, this presence detection will not be considered, and an opening event that would be detected would be considered relevant to generate a detection signal and an alert.
- the removal of the person has the effect of canceling the previous connection, so that the alarm sensor 20 remains active even if the person inside the room is moving closer and away of the sensor.
- the alarm sensor 20 according to this first embodiment is advantageously integrated in a single sensor housing 28 when the opening sensor 21 is composed of a single element.
- the sensor housing 28 is adapted to be fixed on the movable part of the opening 1 (shape, dimensions, ).
- the assembly of the second element 21b, the inhibition device 22, and the electronic unit 23 is integrated in a single sensor housing 28 as shown in FIG. 2. This sensor housing 28 is then adapted to be fixed on the fixed part of the opening 1 (shape, dimensions, ...), or vice versa.
- This alarm sensor 20 can then be connected by an internal connection 29 (sensor-central connection) wired or wireless to a control panel 30 as shown in FIG. 1.
- This alarm central 30 can be a control panel. alarm as currently known, or a simplified control panel 30, and adapted only to the present alarm sensor 20.
- FIG. 2 shows an alarm central unit 30 for the alarm sensor of the first embodiment.
- This central alarm 30 comprises:
- a plant cancellation device 34 which is activated by the identification of an authorized person
- a central alarm device 35 which generates an alert for notifying an intrusion to third parties (for example by a siren, SMS message, etc.).
- the central canceller 34 is adapted to be activated by the identification of a person, and to cancel the alert if the central canceller 34 has been activated for a second duration D2 after the event d 'opening.
- the second duration D2 is adjustable analogically or numerically. It is for example between 10 seconds and 2 minutes. It is for example of the order of 1 minute, so that any alert is removed if a person identifies by the central cancellation device 34.
- the cancellation device of Central 34 is:
- a short-distance badge reader for example of the RFID or NFC type
- a wireless reader adapted to be associated with a mobile wireless electronic device, such as a mobile phone, a connected watch, a badge (electronic card, keychain)

- a keyboard for example of touch or touch type or other
- biometric reader for example of fingerprint recognition type, or recognition of the retina of the eye, or voice recognition, or facial recognition camera, or any other known biometric reader.
- the "wireless" link of the wireless reader uses a medium or long distance wireless transmission means (for example “Bluetooth” or “Bluetooth Low Energy”).
- a medium or long distance wireless transmission means for example “Bluetooth” or “Bluetooth Low Energy”
- the alarm center 30 is completely autonomous and determines itself the nature of the entry (intrusion valid or not).
- this wireless technology is able to estimate a distance between the central canceller device 34 and the wireless electronic device that is worn by the user.
- the distance is determined: according to a transmission power of the wireless electronic device, possibly previously recorded, and / or
- the identification may be validated (i.e. power plant cancellation device 34 activated) if said distance is less than a cancellation distance.
- This cancellation distance is a parameter of the central canceller 34 or cancellation device 24, i.e. a parameter of the alarm sensor 20 and / or the alarm central 30.
- This cancellation distance is for example predetermined, and for example less than 5 meters, and preferably less than 2 meters. This avoids remote sensing cancellations of the alarm sensor 20, without control of the opening and possible intruders.
- This cancellation distance can be set for each application, or set to a value which deactivates said distance condition between the central canceller device 34 and the wireless electronic device, for example for a room with public access in which at unless an authorized person is inside the premises.
- the cancellation distance is for example set to a value less than the range of the wireless electronic device.
- the wireless electronic device uses a wireless transmission means that has a range, i.e., a distance from which it is no longer detectable, ie a distance from which the cancellation device 24 or central canceller 34 will not be able to detect it.
- the wireless electronic device communicates an identifier to the cancellation device 24 or central canceller device 34, and the latter determines the cancellation distance as a function of this identifier.
- each of them can have a different cancellation distance.
- the wireless reader is close to the alarm sensor 20, so that the distance between the wireless reader and the wireless electronic device is substantially equal to the distance between the alarm sensor 20 and the electronic device. wireless.
- the wireless electronic device is optionally remotely programmable by its wireless connection with the central unit 30.
- the range of the wireless electronic device can be adjusted by changing the transmission power.
- the range of the wireless electronic device can then be set to a value slightly greater than the cancellation distance in order to minimize the power consumption of the device wireless electronics.
- the authorized person opens the door 1 from the outside to enter the room must quickly activate the central cancellation device 34 or the cancellation device 24 inside the premises, ie before the end of the second duration D2 that begins at the time of the opening event.
- This action on the central canceller device 34 cancels the generation of the alarm by the alarm center 30.
- it is a wireless electronic device associated with the cancellation device which must quickly activate the device.
- the alarm sensor 20 and / or the alarm center 30 is designed to be in energy saving sleep mode over the largest part of its operation.
- the opening sensor 21 and / or the muting device 22 are permanently active and are able to drive the electronic unit 23 out of the alarm sensor 20, the central unit electronic unit 33 of the central unit. 30, and the cancellation device 24 or the central electronic device 34, from the standby mode to the awake mode. After a delay of inaction after a last event, the electronic unit 23 and the cancellation device 24, 34 automatically return to standby mode.
- the alarm sensor 20 and / or the alarm center 30 consumes little energy.
- the central alarm device 35 is the device that generates the alert for notifying and / or informing one or more third persons that the premises have been the victim of an intrusion. Therefore, "alert" means a signal that is issued to warn people that an intrusion (ie an unauthorized, ie unidentified intrusion) has taken place and that therefore verifications and / or intervention are faster.
- this central alarm device 35 is:
- a communication device adapted to transmit the alert to a remote device, such as a telephone,
- the alert is composed of a first alert generated by a siren and a second alert generated by the communication device; advantageously, the second alert is generated after the first alert, for example after the expiration a period between 10 seconds and 1 minute to possibly still allow time for a user to operate the central canceller device 34 before transmitting the second alert to the remote device (intervention of a security officer).
- the communication element for example transmits the alert via an external link 39 (remote system-alarm device link, i.e. user alarm system or alarm system-security agent):
- WiFi type e.g., GSM
- GSM Global System for Mobile communications
- a network of connected objects e.g. LoRa network, SIGFOX network.
- the central alarm device 35 may, for example, send an SMS or a notification to a remote device of the mobile phone type.
- a push notification or notification uses a notification server that is an intermediary between the central alerting device and the remote device. This server notification is not shown in the figures for reasons of simplification.
- the central alarm device 35 can also transmit via the communication member information messages, different from the alerts, to inform a person of the input / output events of the room. These information messages therefore differ from alerts that correspond to an unauthorized intrusion.
- the alarm control unit 30 according to this first embodiment is advantageously integrated in a single control unit housing 38.
- the alarm system 10 advantageously comprises two modules:
- a first alarm sensor module 20 integrating the opening sensor 21 and the inhibition device 22, formed of one or two housings 28, and
- a second alarm control unit module 30 incorporating the central canceller device 34 and the central alarm device 35, formed of a single casing 38.
- Each of these modules and / or boxes can then be small, which facilitates installation.
- the first module is placed on the fixed or movable part of the opening and the second module is placed near the opening on the wall (for example at arm height to be accessible so that the authorized person can easily activate the alert cancellation).

- the difference between a first signal from the first detection element 222a and a second signal from the second detection element 222b is for example performed by the processing electronics 223 which then provides the motion signal.
- the infrared detector 222 has the following properties:
- this first plane PI in which the alternation of the active and inactive zones has a relatively high density (more than ten, and often more than twenty alternations) which gives a good sensitivity to a transverse movement with respect to the volumetric sensor, this first plane PI corresponding to a plane perpendicular to the infrared detector 222 and passing through the two detection elements 222a, 222b, and
- this second plane P2 perpendicular to the first plane P1, in which the alternation of the active and inactive zones has a relatively low density (less than ten alternations), which gives a poorer sensitivity to a longitudinal movement with respect to the volumetric sensor ( ie in the direction away from the sensor), this second plane P2 corresponding to a plane perpendicular to the infrared detector 222 and passing between the two detection elements 222a, 222b.
- the first plane PI is defined by the points A, D, E

- This wall extends over a separation height 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 of the infrared rays.
- the first signal will have a temporal variation before the second signal, during the passage of the hand, 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 Pl.
- the volumetric sensor will not include an optical system such as lenses, these lenses being replaced by the single wall.
- the inhibition device thus produced will be at the same time more sensitive, more compact, more aesthetic and less expensive than the 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 control unit 30 comprise a deactivation means for effecting this temporary activation / deactivation.
- This action does not require identification of the person, as long as this action is performed outside any entry in the room, ie performed at a non-consecutive time of such an entry.
- This deactivation means may be a button.
- this deactivation means is completed by an alert means which warns the user or users that the alarm sensor 20 and / or the alarm center 30 is inactive, and that the room is not protected.
- This alert can be a visual indication (eg LED) or audible indication or alert transmitted to the wireless electronic device (s) or alert transmitted to one or more mobile phones.
