2874361 12874361 1
La présente invention a pour objet un dispositif d'alarme antivol de voiture destiné à empêcher le vol de voiture par enlèvement. The present invention relates to a car burglar alarm device for preventing car theft by removal.
Le but de l'invention est de venir seul ou en complément 5 d'un antivol existant quel que soit son principe de fonctionnement. The object of the invention is to come alone or in addition to an existing lock whatever its operating principle.
Etant donné l'évolution technologique des systèmes antivol existants, il est difficile pour les personnes mal intentionnées qui souhaitent voler une voiture, de contourner lesdits systèmes antivol. Ces personnes ont donc recours à la technique qui consiste à enlever les véhicules sur des camions en utilisant une grue ou analogue, comme par exemple une dépanneuse. Given the technological evolution of existing antitheft systems, it is difficult for malicious people who wish to steal a car, to bypass said antitheft systems. These people therefore resort to the technique of removing vehicles on trucks using a crane or the like, such as a tow truck.
Les dispositifs antivol existants ne permettent pas d'empêcher l'enlèvement des voitures par enlèvement. C'est pourquoi la présente invention a pour but de proposer un dispositif d'alarme antivol permettant de remédier à cet inconvénient. Existing anti-theft devices do not prevent the removal of cars by removal. This is why the present invention aims to provide a burglar alarm device to remedy this drawback.
Le dispositif d'alarme antivol selon l'invention se caractérise essentiellement en ce qu'il comprend des moyens de mesure aptes à mesurer la distance séparant le véhicule du sol, des moyens aptes à détecter une variation de ladite distance, et des moyens d'alarme sonores et/ou visuels aptes à se déclencher lorsque ladite variation dépasse un certain seuil. The anti-theft alarm device according to the invention is essentially characterized in that it comprises measuring means able to measure the distance separating the vehicle from the ground, means capable of detecting a variation of said distance, and means for audible and / or visual alarms capable of being triggered when said variation exceeds a certain threshold.
Selon une caractéristique additionnelle du dispositif selon l'invention, il comporte des moyens permettant sa mise en fonctionnement de manière automatique après arrêt et fermeture du véhicule. According to an additional characteristic of the device according to the invention, it comprises means enabling it to be put into operation automatically after stopping and closing the vehicle.
Selon un mode de réalisation particulier du dispositif selon l'invention, les moyens de mesure comportent une cellule de télémétrie qui mesure la distance entre la caisse du véhicule et le sol. According to a particular embodiment of the device according to the invention, the measuring means comprise a telemetry cell which measures the distance between the vehicle body and the ground.
Selon un autre mode de réalisation du dispositif selon l'invention, les moyens de mesure comportent une cellule photoélectrique qui utilise le principe de triangulation pour 35 calculer la variation de ladite distance. According to another embodiment of the device according to the invention, the measuring means comprise a photoelectric cell which uses the principle of triangulation to calculate the variation of said distance.
D'autres caractéristiques et avantages de l'invention 2874361 2 ressortiront de la description détaillée qui va suivre des modes de réalisation non limitatifs de l'invention. Other features and advantages of the invention will emerge from the following detailed description of non-limiting embodiments of the invention.
L'invention a trait à un dispositif d'alarme antivol de voiture pour empêcher le vole de voiture par enlèvement. The invention relates to a car burglar alarm device for preventing car theft by removal.
Le dispositif selon l'invention peut comprendre, comme tout type de système d'alarme antivol, des moyens d'alarme sonores et/ou visuels aptes à être déclenchés. De plus, il peut comporter des moyens de communication à des centrales de surveillance ou prévenir directement le propriétaire de la voiture au travers d'un terminal portable, comme par exemple en utilisant le réseau de communication GSM et un téléphone cellulaire. The device according to the invention may comprise, as any type of burglar alarm system, audible and / or visual alarm means capable of being triggered. In addition, it may include means of communication to central monitoring or directly notify the owner of the car through a portable terminal, such as using the GSM communication network and a cell phone.
Pour éviter l'enlèvement de la voiture, il a été imaginé de mesurer la fluctuation de distance séparant la voiture du sol, en particulier la distance entre le châssis ou la caisse du véhicule et la chaussée. To avoid the removal of the car, it has been imagined to measure the distance fluctuation separating the car from the ground, in particular the distance between the chassis or the vehicle body and the road.
Pour ce faire, le dispositif selon l'invention comprend des moyens conçus aptes à mesurer la distance séparant le véhicule du sol. Une fois la mesure effectuée, elle est stockée pour être comparée avec une mesure effectuée ultérieurement. Des moyens conçus aptes à détecter une variation de cette distance sont donc mis en oeuvres. En cas de dépassement d'une valeur seuil, qui peut être réglée par l'utilisateur ou en fonction du type de véhicule ou de certaines caractéristiques techniques de ce dernier, les moyens d'alarme sont déclenchés. To do this, the device according to the invention comprises means designed to measure the distance separating the vehicle from the ground. Once the measurement is done, it is stored for comparison with a measurement made later. Means designed to detect a variation of this distance are therefore implemented. If a threshold value is exceeded, which can be set by the user or according to the type of vehicle or certain technical characteristics of the latter, the alarm means are triggered.
Dans un mode de réalisation du dispositif selon l'invention, ces moyens de mesure sont constitués par au moins une cellule de télémétrie qui mesure la distance entre le véhicule et le sol. La distance mesurée peut être multipliée par un coefficient de tolérance afin d'éviter les déclenchements intempestifs. In one embodiment of the device according to the invention, these measuring means are constituted by at least one telemetry cell which measures the distance between the vehicle and the ground. The measured distance can be multiplied by a tolerance factor in order to avoid nuisance tripping.
Dans un autre mode de réalisation du dispositif, les moyens de mesure sont constitués par au moins une cellule photoélectrique, dite à proximité avec suppression d'arrière- plan. Ce capteur photoélectrique utilise le principe de triangulation pour calculer la variation de ladite distance. In another embodiment of the device, the measuring means consist of at least one photoelectric cell, said near with background suppression. This photoelectric sensor uses the principle of triangulation to calculate the variation of said distance.
2874361 3 D'autres moyens sont conçus apte à supprimer toute interférence d'un arrière-plan, même proche à détecter, afin d'éviter tout masquage de ladite cellule et empêcher le calcul de la distance. Other means are designed capable of removing any interference from a background, even close to detect, to prevent any masking of said cell and prevent the calculation of the distance.
Le dispositif comprend des moyens de mise en fonctionnement de manière automatique après arrêt et fermeture du véhicule. The device comprises means for putting into operation automatically after stopping and closing the vehicle.
A ce moment, une mesure témoin est effectuée et mémorisée pour le calcul ultérieur des variations de distance entre le véhicule et le sol. La garde au sol étant déterminée au moment de la fermeture du véhicule, une variation de cette garde au sol dans une proportion prédéfinie, enclenche automatiquement les moyens d'alarme. Pour ce faire, les moyens de mesure effectuent des mesurent périodiquement, selon une durée éventuellement réglable par l'utilisateur. At this time, a control measurement is made and stored for the subsequent calculation of the distance variations between the vehicle and the ground. The ground clearance being determined at the time of closure of the vehicle, a variation of this ground clearance in a predefined proportion, automatically triggers the alarm means. To do this, the measuring means perform measurements periodically, according to a duration possibly adjustable by the user.
Le dispositif comprendra des moyens d'arrêt lors de la remise en service ou en fonctionnement du véhicule ou permettant à l'utilisateur de stopper les signaux d'alarme. The device will include stopping means during the return to service or operation of the vehicle or allowing the user to stop the alarm signals.
Le dispositif peut être autoalimenté, par exemple comme un système d'antivol classique. The device can be self-powered, for example as a conventional anti-theft system.
Le dispositif selon l'invention empêche donc le vol de voiture par enlèvement. De plus, il peut être utilisé seul ou facilement adaptable en combinaison avec un dispositif antivol existant. The device according to the invention thus prevents car theft by removal. In addition, it can be used alone or easily adaptable in combination with an existing antitheft device.
Bien entendu, l'invention n'est pas limitée aux exemples illustrés et décrits précédemment qui peuvent présenter des variantes et modifications sans pour autant sortir du cadre de l'invention. Of course, the invention is not limited to the examples illustrated and described above which may have variants and modifications without departing from the scope of the invention.
