Description

L'invention a pour objet un procédé de surveill,ince et d'alarme dont les moyens de détection sont progressifs pour analyser l'intensité de l'effraction et les moyens de dissuasion et d'alarme sont progressifs en intensité, en qualité et en durée, et ce, en fonction de la détection.The subject of the invention is a monitoring, detection and alarm method, the detection means of which are progressive in order to analyze the intensity of the break-in and the deterrent and alarm means are progressive in intensity, in quality and in duration, depending on the detection.

Les installations d'alarme, réalisées jusqu'à ce jour, sont conçues suivant des schémas synoptiques à peu près analogues.The alarm installations, carried out to date, are designed according to roughly analogous synoptic diagrams.

Une ou plusieurs boucles de détecteurs, périphériques ou volumétriques, sont raccordées aux entrées d'une Centrale d'alarme. La Centrale a pour fonctions de surveiller les divers capteurs, de façons appropriées au principe de fonctionnement de chacun d'eux, et de déclencher l'alerte quand une perturbation est décelée par l'un d'entre eux.One or more detector loops, peripheral or volumetric, are connected to the inputs of an alarm center. The control panel has the function of monitoring the various sensors, in ways appropriate to the operating principle of each of them, and of triggering the alert when a disturbance is detected by one of them.

L'alerte est donnée par divers moyens sonores ou lumineux, ou retransmis à distance par radio ou ligne téléphonique. Les avertisseurs sonores, utilisés le plus couramment comme moyen d'alerte, sont choisis de façon à libérer une puissance acoustique considérable, qui devra être entendue, le plus loin possible, par le voisinage.The alert is given by various sound or light means, or retransmitted remotely by radio or telephone line. Audible warning devices, most commonly used as a warning device, are chosen so as to release considerable acoustic power, which must be heard as far away as possible by the neighborhood.

Sur les centrales les plus sophistiquées, une boucle d'accès permet de brancher, de façon spécifique, le ou les détecteurs surveillant la porte par laquelle l'utilisateur. va pénétrer dans le local sous surveillance. Cela permet d'éviter d'utiliser un contact à serrure placé hors de la zone protégée, pour la mise sous tension ou l'arrêt du système.On the most sophisticated control panels, an access loop makes it possible to connect, in a specific way, the detector (s) monitoring the door through which the user. will enter the premises under surveillance. This avoids the use of a lock contact placed outside the protected area, to power on or shut down the system.

L'utilisateur pourra entrer par la porte, ainsi équipée, sans déclencher l'alarme. Une préalarme, matérialisée par un voyant lumineux ou un buzzer de faible niveau sonore, le préviendra qu'il doit arrêter la centrale, avant la fin de la temporisation déclenchée par l'ouverture de la porte. Si la centrale n'a pas été stoppée, dans le délai prévu, l'alerte sera donnée.The user will be able to enter through the door, thus equipped, without setting off the alarm. A pre-alarm, materialized by an indicator light or a buzzer of low sound level, will warn him that he must stop the control panel, before the end of the delay triggered by the opening of the door. If the control panel has not been stopped, within the planned time, the alert will be given.

Dans tous les cas, lorsqu'un détecteur enregistre une perturbation, l'alerte sera donnée avec tous les moyens puissants prévus à cet effet. Soit, immédiatement, pour les boucles normales, soit, après un retard, pour la boucle d'accès temporisée.In all cases, when a detector registers a disturbance, the alert will be given with all the powerful means provided for this purpose. Either immediately for normal loops or, after a delay, for the timed access loop.

Les plus gros problèmes, provoqués par les installations d'alarme viennent de cette caractéristique commune à tous les systèmes actuels. En effet, les exigeances de sécurité, conjuguées avec les progrès technologiques, incitent les installateurs à utiliser des détecteurs de plus en plus sensibles, et à essayer de détecter les tentatives d'intrusion le plus tôt possible, de préférence avant que l'intrus se soit introduit sur les lieux.The biggest problems caused by alarm installations come from this characteristic common to all current systems. Indeed, the security requirements, combined with technological progress, encourage installers to use increasingly sensitive detectors, and to try to detect intrusion attempts as soon as possible, preferably before the intruder has entered the premises.

Malheureusement, dans les deux cas, on parvient au même résultat négatif : la prolifération d'un nombre de plus en plus important de déclenchements intempestifs. La différence entre une tentative d'intrusion et une perturbation d'origine atmosphèrique, électromagnétique ou thermique est parfois très ténue, ou même inexistante. Par exemple, l'action d'un vent violent, sur une porte mal ajustée, sera identique à celui de l'introduction d'un pied- de-biche, entre la porte et le cadre, pour un détecteur inertiel placé sur le dormant de l'ouverture.Unfortunately, in both cases, the same negative result is achieved: the proliferation of an increasing number of nuisance trips. The difference between an attempted intrusion and a disturbance of atmospheric, electromagnetic or thermal origin is sometimes very tenuous, or even non-existent. For example, the action of a strong wind, on a poorly adjusted door, will be identical to that of the introduction of a presser foot, between the door and the frame, for an inertial detector placed on the frame. of the opening.

L'effet des déclenchements intempestifs sur le voisinage et sur les utilisateurs eux-mêmes est désastreux. Ils dévalorisent l'alarme électronique et la discrédite aux yeux des clients potentiels.The effect of nuisance trips on the neighborhood and on the users themselves is disastrous. They devalue the electronic alarm and discredit it in the eyes of potential customers.

Les chercheurs et les fabricants de matériel d'alarme s'ingénient à étudier des détecteurs de plus en plus complexes, pour éviter ces problèmes.Researchers and alarm equipment manufacturers are working to study increasingly complex detectors to avoid these problems.

L'invention est née de la réflexion sur les finalités de l'alarme électronique. Ce type d'installations n'est pas destiné à permettre la capture des voleurs, mais à dissuader cieux-ci de commettre leurs méfaits.The invention was born from thinking about the purposes of the electronic alarm. This type of facility is not intended to capture thieves, but to deter them from committing their crimes.

Le procédé selon l'invention et le dispositif pour la mise en oeuvre de l'invention évitent tous les inconvénients cités plus haut.The method according to the invention and the device for implementing the invention avoid all the drawbacks mentioned above.

La très grosse majorité des installations est réalisée chez des particuliers qui ne sont pas des cibles privilégiées pour les malfaiteurs, ce sont des gens ayant une certaine aisance matérielle, mais dont les logements ne recellent aucun trésor, ou collection de très grand prix. Rien ne les désigne spécialement aux voleurs, ceux-ci s'attaquent à ce type de victimes d'autant plus volontiers que les défences qu'ils rencontrent seront plus faibles et ne mettront pas en danger leur propre sécurité.The vast majority of installations are carried out with individuals who are not preferred targets for criminals, they are people with a certain material ease, but whose housing contains no treasure, or collection of very great prices. Nothing designates them especially for thieves, they attack this type of victims all the more willingly as the defenses they meet will be weaker and will not endanger their own safety.

Ainsi, pour les appartements situés dans. de grands immeubles, il a suffi, pendant longtemps, d'équiper la porte d'une serrure un peu supérieure à celles du voisinage-, avec des renforts sur plusieurs points de l'encadrement, pour que les intrus l'évi- voisinage, il passera inapperçu.So, for apartments located in. large buildings, it was enough, for a long time, to equip the door with a lock a little higher than those of the neighborhood, with reinforcements on several points of the frame, so that intruders could neighborhood, it will go unnoticed.

Par contre, si une intrusion est poursuivie, malgré la dissuasion du coup de semonce provoqué par le premier niveau de détection, le second niveau interviendra et déclenchera l'alerte la plus tonitruante.
chaque détecteur sera accompagné d'un buzzer ou d'un voyant qui signalera l'action du premier niveau de détection aux abords immédiats de l'ouverture protégée, sans provoquer de gène dans le voisinage immédiat ou dans le logement.On the other hand, if an intrusion is pursued, despite the deterrence of the warning shot caused by the first level of detection, the second level will intervene and trigger the most thunderous alert.
each detector will be accompanied by a buzzer or an indicator light which will signal the action of the first level of detection in the immediate vicinity of the protected opening, without causing discomfort in the immediate vicinity or in the accommodation.

La dissuasion n'en est pas moins totale. Quel intrus s'attaquant par hazard à l'ouverture, continuera tranquillement sa tentative d'intrusion après avoir été prévenu que celle-ci a été détectée ?The deterrence is nonetheless total. Which intruder attacking by chance at the opening, will quietly continue his attempt to intrude after being warned that it has been detected?

s'il s'agit d'un passant innocent, qui a fait un faux-pas ou a frappé un peu trop fort sur la porte, il n'est pas mauvais de l'informer qu'un système de surveillance sophistiqué veille sur l'ouverture et donc, sans doute sur l'ensemble du logement.if it is an innocent bystander, who has made a faux pas or has knocked a little too hard on the door, it is not bad to inform him that a sophisticated surveillance system watches over the 'opening and therefore, probably on the whole housing.

Le procédé selon l'invention consiste donc à placer des récepteurs dont les informations sont traités par un analyseur électronique qui, en fonction de l'information, renvoie immédiatement sur le lieu de la détection, un signal message dissuasif informant le provocateur qu'il y a une surveillance électronique qui a déjà détecté et compris quel était le degré d'alerte ; si le ou les détecteurs continuent à être actionnés au même niveau de détection ou à un niveau supérieur de détection, le message dissuasif est délivré dans un rayon plus grand, il peut augmenter en durée et en intensité, tandis que l'analyseur électronique actionne une alarme progressive en durée et en intensité qui renseigne exactement les intéressés sur le type et l'état d'avancement de l'effraction.The method according to the invention therefore consists in placing receivers whose information is processed by an electronic analyzer which, depending on the information, immediately sends back to the place of detection, a dissuasive message signal informing the provocateur that there has electronic surveillance which has already detected and understood the level of alert; if the detector or detectors continue to be actuated at the same level of detection or at a higher level of detection, the dissuasive message is delivered in a larger radius, it can increase in duration and in intensity, while the electronic analyzer actuates a progressive alarm in duration and intensity which gives precise information to those concerned about the type and progress of the break-in.

Le dispositif selon l'invention comporte des détecteurs inertiels, dont les informations vont vers un analyseur électronique, cet analyseur comporte au moins deux niveaux de détection, le premier niveau se borne à renvoyer immédiatement, par un temporisateur et un circuit de puissance, un signal message dissuasif au provocateur, donc sur le lieu de la détection, le second niveau de détection agit sur d'autres circuits par un autre temporisateur et un circuit de puissance qui actionne une ou plusieurs alarmes et ce, suivant une graduation. tent, au détriment des portes environnantes moins bien défendues. La généralisation de ce genre de serrure a provoqué une évolution des techniques d'intrusion, ce qui pousse actuellement les compagnies d'assurance à préconiser l'alarme comme moyen de défense. Or, l'alarme, si elle veut être aussi dissuasive que les serrures multipoints l'ont été pendant longtemps, doit se signaler le plus tôt possible à l'attention du malfaiteur, de préférence avant que celui-ci n'ait abimé la porte.The device according to the invention comprises inertial detectors, the information of which goes to an electronic analyzer, this analyzer comprises at least two detection levels, the first level is limited to immediately returning, by a timer and a power circuit, a signal dissuasive message to the provocateur, therefore on the place of detection, the second level of detection acts on other circuits by another timer and a power circuit which activates one or more alarms and this, according to a graduation. tent, to the detriment of the surrounding doors which are less well defended. The generalization of this kind of lock has provoked an evolution in intrusion techniques, which is currently pushing insurance companies to recommend the alarm as a defense. However, the alarm, if it is to be as dissuasive as multipoint locks have been for a long time, must be reported as soon as possible to the attention of the perpetrator, preferably before the latter has damaged the door .

C'est ici que réapparaissent les déclenchements intempestifs !This is where untimely triggers reappear!

L'invention évite tous ces inconvénients, elle consiste à équiper les ouvertures que l'on veut surveiller, avec des détecteurs inertiels bien choisis, dont les informations seront traitées par un analyseur électronique très évolué, qui discrimine, avec un maximun de sécurité, celles provenant des perturbations normales de l'ambiance, et celles venant des tentatives d'intrusions éventuelles.The invention avoids all these drawbacks, it consists in equipping the openings that one wants to monitor, with well chosen inertial detectors, the information of which will be processed by a very advanced electronic analyzer, which discriminates, with maximum safety, those from normal disturbances in the atmosphere, and those from possible intrusion attempts.

Au niveau de la centrale d'alarme, il est prévu au moins deux niveaux de détection

  • a) - Un niveau très sensible qui déclenche une action, par exemple quand un voisin butera, malencontreusement, sur le pail- lason placé contre la porte.
  • b) - Un second niveau de détection moins sensible, donc plus fiable, ne déclenche une action, par exemple, uniquement à l'ouverture de la porte.
At the alarm center level, at least two detection levels are provided
  • a) - A very sensitive level that triggers an action, for example when a neighbor accidentally comes up against the doorstop placed against the door.
  • b) - A second, less sensitive, and therefore more reliable, detection level does not trigger an action, for example, only when the door is opened.

Le premier niveau de détection ne provoquera pas le démarrage de l'alerte générale, avec les divers moyens prévus : sirène, transmission à distance... Il ne fera que signaler, par des moyens sonores ou lumineux de courte durée et de faible niveau, qu'un système de surveillance électronique est installé sur l'ouverture et qu'il sera à même de déclencher une alerte beaucoup plus puissante si la tentative d'intrusion continue ou progresse en intensité.The first level of detection will not cause the start of the general alert, with the various means provided: siren, remote transmission ... It will only signal, by short or low-level sound or light means, that an electronic surveillance system is installed on the opening and that it will be able to trigger a much more powerful alert if the intrusion attempt continues or increases in intensity.

Le message dissuasif ne sera délivré que dans un rayon très faible autour de l'ouverture, et ne sera perçu, ni par les voisins, ni par l'utilisateur lui-même, s'il est présent chez lui, en éveil ou endormi, sauf, bien sur, s'il est à proximité 'de l'ouverture.The dissuasive message will only be delivered within a very small radius around the opening, and will not be perceived, either by the neighbors, or by the user himself, if he is at home, awake or asleep, except, of course, if it is near the opening.

Si de temps à autre, un déclenchement intempestif surprend la sagacité de l'analyseur, en raison de la très grande sensibilité de la détection, cela ne provoquera pas un drame dans leIf from time to time an untimely trigger surprises the sagacity of the analyzer, due to the very high sensitivity of the detection, this will not cause a drama in the

La figure unique annexée se rapporte au schéma fonctionnel d'une réalisation pratique préférentielle de la centrale constituant la présente invention.The single appended figure relates to the functional diagram of a preferred practical embodiment of the plant constituting the present invention.

Les ouvertures à surveiller : 1, 2, 3 et 4, sont indifféremment des portes ou des fenêtres. Elles sont équipées de capteurs inertiels combinés avec des contacts magnétiques 5, 6, 7 et 8 de façon à ce que les boucles de fils B1, B2, B3' B4 qui les relient à la centrale, faisant l'objet de la présente invention, soient fermées en permanence, quand l'ouverture est close et s'ouvrent, fugitivement quand elle est soumise à des vibrations ou de façon stable, quand elle est ouverte.The openings to watch: 1, 2, 3 and 4, are either doors or windows. They are equipped with inertial sensors combined with magnetic contacts 5, 6, 7 and 8 so that the wire loops B 1 , B 2 , B 3 ' B 4 which connect them to the central unit, being the subject of the present invention, are closed permanently, when the opening is closed and open, fleetingly when it is subjected to vibrations or stably, when it is open.

Chaque boucle B1, B2' B3 et B4 arrive sur un circuit distinct 9, 10, 11 ou 12, qui assure un filtrage des informations, concervant celles qui correspondent à des vibrations mécaniques, enregistrées par le capteur et rejetant à la masse les signaux d'origine électromagnétiques ou électriques induits sur les fils. Les mêmes circuits 9, 10, 11 et 12 mettent en forme les signaux conservés pour que leur traitement puisse se faire à niveaux logiques.Each loop B 1 , B 2 ' B 3 and B 4 arrives on a separate circuit 9, 10, 11 or 12, which filters the information, keeping those which correspond to mechanical vibrations, recorded by the sensor and rejecting the ground the signals of electromagnetic or electrical origin induced on the wires. The same circuits 9, 10, 11 and 12 shape the stored signals so that their processing can be done at logic levels.

Chaque circuit de mise en forme 9, 10, 11 et 12 est relié à une mémoire de localisation spécifique 13, 14, 15 ou 16 qui conserve l'information donnant l'origine du signal qui est parvenu à la centrale. Ces mémoires 13, 14, 15 ou 16 sont remises à zéro cycliquement de façon à conserver uniquement les informations correspondant aux signaux qui sont en cours de traitement dans les analyseurs 17, 18 et 19. Le premier, 17, est très sensible, il peut être déclenché par une vibration de faible amplitude. Le second, 18, est d'une sensibilité moyenne, il ne répond qu'aux chocs assez violents reçus par l'ouverture. Les analyseurs 17 et 18 qui sont déclenchés par des signaux, faibles et moyens, mettent en action des moyens dissuasifs qui ne sont perçus qu'a proximité très immédiate du point 1, 2, 3, ou 4, où est émis le signal, et ne sont pas entendus par le voisinage immédiat et les occupants du local à protéger. Le troisième est peu sensible et demande des signaux d'une durée importante, que seuls les contacts magnétiques sont à même de générer. Les trois analyseurs 17, 18 et 19 sont attaqués, simultanément, par l'ensemble des signaux issus des circuits de mise en forme : 9, 10, 11 et 12. Suivant l'intensité de la perturbation agissant sur l'ouverture, aucun ne sera déclenché ou seulement le plus sensible 17, ou le 17 et le 18, ou enfin, le 17, le 18 et le 19.Each shaping circuit 9, 10, 11 and 12 is connected to a specific location memory 13, 14, 15 or 16 which stores the information giving the origin of the signal which has reached the central station. These memories 13, 14, 15 or 16 are reset cyclically to keep only the information corresponding to the signals which are being processed in the analyzers 17, 18 and 19. The first, 17, is very sensitive, it can be triggered by a low amplitude vibration. The second, 18, is of medium sensitivity, it only responds to fairly violent shocks received by the opening. The analyzers 17 and 18 which are triggered by weak and medium signals put into action dissuasive means which are only perceived very close to point 1, 2, 3, or 4, where the signal is emitted, and are not heard by the immediate vicinity and the occupants of the room to be protected. The third is not very sensitive and requires long duration signals, which only the magnetic contacts are able to generate. The three analyzers 17, 18 and 19 are attacked simultaneously by all the signals from the shaping circuits: 9, 10, 11 and 12. Depending on the intensity of the disturbance acting on the opening, none will be triggered or only the most sensitive 17, or the 17 and the 18, or finally, the 17, the 18 and the 19.

Lorsque le seuil d'un analyseur est atteint, celui-ci déclenche un circuit suivant qui détermine la durée pendant laquelle l'action dissuasive va se faire. Les trois circuits de temporisation 20, 21 et 22 font suite, respectivement aux analyseurs 17, 18 et 19. Chacun est réglable sur sa propre valeur de temps. Le 20 correspondant aux perturbations légères commandera, une action de quelques secondes. Le 21, correspondant aux chocs moyens et forts, agira pendant un temps légèrement plus long. Le 22 correspondant aux intrusions caractérisées, déterminera une action dissuasive de une à trois minutes, cette dernière valeur étant le maximum légal pour le fonctionnement d'une sirène sur la voie publique.When the threshold of an analyzer is reached, it triggers a following circuit which determines the duration during which the deterrent action will take place. The three timing circuits 20, 21 and 22 follow, respectively, the analyzers 17, 18 and 19. Each is adjustable to its own time value. The 20 corresponding to light disturbances will command an action of a few seconds. The 21, corresponding to medium and strong shocks, will act for a slightly longer time. The 22 corresponding to the characterized intrusions, will determine a deterrent action of one to three minutes, this last value being the legal maximum for the functioning of a siren on the public highway.

A ce point de la description de la figure 1, le dispositif permet d'effectuer un tri dans les signaux, issus des capteurs 5, 6, 7 et 8 montés sur les ouvertures et de déclencher trois types d'actions distinctes, de durées différentes.At this point in the description of FIG. 1, the device makes it possible to sort the signals from the sensors 5, 6, 7 and 8 mounted on the openings and to trigger three distinct types of actions, of different durations .

La voie très sensible constituée par l'analyseur 17 et le temporisateur 20, agira, en parallèle sur les quatre circuits de puissance 23, 24, 25 et 26 reliés respectivement aux dispositifs dissuasifs 27, 28, 29 et 30.The very sensitive channel constituted by the analyzer 17 and the timer 20, will act, in parallel on the four power circuits 23, 24, 25 and 26 connected respectively to the dissuasive devices 27, 28, 29 and 30.

Les circuits de puissance sont attaqués, par le temporisateur 20, sur une entrée libérant la demi-puissance disponible. Ils sont inhibés, en permanence, et débloqués uniquement sous l'action de la mémoire correspondante 13, 14, 15 ou 16. Ainsi, seul l'élément dissuasif placé prés de l'ouverture qui a été ébranlée par - la vibration, recevra la demi-puissance déclenchée par l'analyseur sensible 17.The power circuits are attacked, by the timer 20, on an input releasing the available half-power. They are permanently inhibited, and unlocked only under the action of the corresponding memory 13, 14, 15 or 16. Thus, only the deterrent placed near the opening which has been shaken by - the vibration, will receive the half power triggered by the sensitive analyzer 17.

La voie de sensibilité moyenne, constituée par l'analyseur 18 et la temporisation 21, agira sur les quatre circuits de puissance, simultanément, mais cette fois-ci, sur une entrée libérant la pleine puissance. Et, de même que précédemment, seul le circuit correspondant à l'ouverture perturbée sera désinhibé par la mémoire qui lui est affectée. L'action dissuasive s'effectuera dans les mêmes conditions que pour la voie très sensible, mais avec une intensité plus forte et une durée plus longue.The medium sensitivity channel, constituted by the analyzer 18 and the time delay 21, will act on the four power circuits, simultaneously, but this time, on an input releasing full power. And, as previously, only the circuit corresponding to the disturbed opening will be inhibited by the memory assigned to it. The deterrent action will be carried out under the same conditions as for the very sensitive route, but with a stronger intensity and a longer duration.

Si plusieurs ouvertures sont agressées simultanément, les moyens dissuasifs, qui leur sont affectés, entreront en action simultanément.If several openings are attacked simultaneously, the deterrents, which are assigned to them, will come into action simultaneously.

Quand la voie de sensibilité moyenne est activée, la voie sensible l'est, naturellement, en même temps. L'action dissuasive de la voie moyenne couvre celle de la voie sensible par une intensité plus grande et une durée plus longue.When the medium sensitivity channel is activated, the sensitive channel is, of course, at the same time. The deterrent action of the middle way covers that of the sensitive way by a greater intensity and a longer duration.

Si l'analyseur 19 est déclenché par une perturbation correspondant à une intrusion caractérisée, il agira sur le temporisateur 22 qui actionnera sa voie de puissance spécifique 31. Celle-ci commandera le dispositif dissuasif 32 qui lui est connectée . Celui-ci pourra être constitué par l'un des appareils sonores, lumineux ou de transmission à distance connus ou par une combinaison de plusieurs d'entre eux.If the analyzer 19 is triggered by a disturbance corresponding to a characterized intrusion, it will act on the timer 22 which will activate its specific power channel 31. This will control the deterrent device 32 which is connected to it. This could be constituted by one of the known sound, light or remote transmission devices or by a combination of several of them.

La durée d'action, dans le cas d'une sirène, sera comprise entre une et trois minutes, comme nous l'avons vu plus haut.The duration of action, in the case of a siren, will be between one and three minutes, as we saw above.

L'ouverture ayant subi l'intrusion recevra l'alerte dissuasive dans les conditions vues au paragraphe traitant de la voie de sensibilité moyenne 19 et 22.The opening having undergone the intrusion will receive the deterrent alert under the conditions seen in the paragraph dealing with the medium sensitivity pathway 19 and 22.

Les moyens de dissuasion 27, 28, 29 et 30 peuvent être de différents types, ainsi ils peuvent être lumineux, sonores et en particulier il peut s'agir d'un message vocal enregistré sur un support magnétique ou synthétisé par un circuit électronique.The deterrent means 27, 28, 29 and 30 can be of different types, so they can be light, sound and in particular it can be a voice message recorded on a magnetic medium or synthesized by an electronic circuit.
