Abstract

The invention relates to a device making it possible to trigger a sound system using both a system for detection of change to the internal volume of the vehicle combining the ultrasound or infrared and UHF systems. It consists of two detection systems, one ultrasonic or infra-red and the other UHF, the two systems operating in totally different frequencies i.e. a few tens of kilohertz for the infrared or ultrasonic system and a few thousand megahertz for the UHF system. The two detection systems are coupled and only put the alarm system into operation as long as both of the two systems simultaneously receive the information. The device according to the invention is particularly intended for protection of any vehicle and more particularly automobiles.

Description

Tn plAscllte invention concerne un dispositif d'alarnr: i détection par hyperfréquence destiné plus particulièrement aux véhicules autonobiles.  Tn plAscllte invention relates to a device alarnr: i microwave detection intended more particularly for motor vehicles.

Actuellement toutes les alarmes - ultra-sons utilisent l'effet "do ppler".  Currently all alarms - ultrasounds use the "do ppler" effect.

Dans les procédés existants, un ou deux détecteurs à ultra-sons ou infra rouge sont plasés à l'intérieur de lthabitacle du véhicule et mesurent en permanence le volume interieur du véhicule, les ultra-sons fonctionnant dans des fréquences de quelques dizaines de kilohertz. Lors d'une intrusion, la variation de volume ou le moindre mouvement à l'intérieur de l'habitacle, provoque un déphasage dans le systeme qui a pour effet de déclencher l'avertisseur sonore du véhicule pour une durée de trente secondes maximum, pour être en règle avec le code de la route. In existing methods, one or two ultrasonic or infrared detectors are placed inside the vehicle cabin and permanently measure the interior volume of the vehicle, the ultrasound operating in frequencies of a few tens of kilohertz. During an intrusion, the change in volume or the slightest movement inside the passenger compartment, causes a phase shift in the system which has the effect of triggering the vehicle's horn for a duration of maximum thirty seconds, to be in good standing with the highway code.

Le déclenchement peut-être instantané ou temporisé pour permettre de mettre l'interrupteur de commande à l'intérieur, mais dans tous les cas, un mouvement ayant provoqué le déphasage, fait automatiquement déclencher le sys tème; si l'information qui fait déclencher le système est une information intempestive tel que mouvement de l'air par le soleil, émission puissante de C,B, etc le déclenchement intempestif dùrera trente secondes et se reproduire autant de fois qu'une information intempestive est enregistrée. Triggering can be instantaneous or timed to allow the control switch to be placed inside, but in all cases, a movement having caused the phase shift, automatically triggers the system; if the information which triggers the system is untimely information such as movement of the air by the sun, powerful emission of C, B, etc. the untimely triggering will take thirty seconds and reproduce as many times as untimely information is saved.

Le dispositif selon l'invention permet de remédier à cet inconvénient. The device according to the invention overcomes this drawback.

I1 comporte en effet un système d'alarme à détection par hyperfréquence, iden tique au système à ultra-sons, mais avec des fréquences totalement différent
tes systèmes à hyperfréquence fonctionnent dans des fréquences de quelques milliers de mégahertz. tes ondes hyperfréquences passent à travers pratiquement tous les matériaux sauf le métal.I1 indeed includes a microwave detection alarm system, identical to the ultrasonic system, but with totally different frequencies
your microwave systems operate in frequencies of a few thousand megahertz. your microwave waves pass through almost all materials except metal.

Dans un véhicule les ondes hyperfréquences passent à travers les glace mais pas à travers la tôle ; il faut donc un réglage très précis dans le bas du véhicule pour éviter le passage à travers les vitres. Les alarmes à declen chement par ultra-sons ou par hyperfréquences sont toutes deux des appareils à détection volumétriques. In a vehicle microwave waves pass through the ice but not through the sheet metal; a very precise adjustment is therefore necessary at the bottom of the vehicle to avoid passing through the windows. Both ultrasonic and microwave alarms are volumetric detection devices.

Le dispositif selon l'invention ne peut avoir de déclenchement intempestif par mouvement de l'air provoqué par le soleil non plus que par les choc courants d'air ou émission puissante de C.B. te risque de déclenchement intempestif du système utilisant l'hyperfréquence ne peut provenir que d'un mau vais réglage ou d'un faisceau d'onde passant à traversles glaces. Le dispositif selon l'invention consiste à utiliser à la fois les ultra-sons ou in fra-rouges et l'hyperfréquence simultanément, l'alarme ne se déclenchant que
lorsqu'elle a reçu l'information volumétrique des deux systèmes, chaque pro cddé pris indépendamment l'un de l'autre n1 ayant aucun effet sur ledit systèn d'alarme. The device according to the invention can not have untimely triggering by movement of the air caused by the sun any more than by the shock of air currents or powerful emission of CB te risk of untimely triggering of the system using the hyper frequency cannot come from a wrong setting or from a wave beam passing through the glass. The device according to the invention consists in using both ultrasound or in-fr-red and hyperfrequency simultaneously, the alarm only being triggered
when it has received the volumetric information from the two systems, each pro cdd taken independently of the other having no effect on said alarm system.

Le dispositif selon l'invention conslste donc à utiliser à la fois et simultanément les deux procédés, savoir ultra-sons ou infra-rouge et hyperfréquences. The device according to the invention therefore conslste to use both and simultaneously the two methods, namely ultrasound or infrared and microwave.

te dispositif selon l'invention est particulièrement destiné à la protection par alarme sonore de tous véhicules et notamment des véhicules automobiles.  The device according to the invention is particularly intended for the protection by audible alarm of all vehicles and in particular motor vehicles.
