Description

La présente invention concerne les dispositifs et procédés visant à aider à retrouver des objets volés.The present invention relates to devices and methods for assisting in locating stolen objects.

L'invention s'intéresse plus particulièrement mais non exclusivement à une solution permettant de retrouver des paquets de cigarettes volés.The invention is more particularly, but not exclusively, concerned with a solution making it possible to find stolen packets of cigarettes.

On connaît des systèmes antivols embarqués sur des véhicules automobiles, comportant un moyen de géolocalisation et un émetteur permettant de transmettre des données de géolocalisation à un réseau de téléphonie mobile. Le système est activé via le réseau de téléphonie en cas de vol.Antitheft systems on board motor vehicles are known, comprising a geolocation means and a transmitter making it possible to transmit geolocation data to a mobile telephone network. The system is activated via the telephone network in the event of theft.

Un tel système est relativement complexe et coûteux et nécessite d'être connecté à la batterie du véhicule dans l'état de veille. Il ne convient pas à la protection d'objets ne pouvant bénéficier d'une source d'énergie électrique de forte capacité telle qu'une batterie automobile ou d'une connexion au secteur.Such a system is relatively complex and expensive and needs to be connected to the vehicle battery in the standby state. It is not suitable for protecting objects that cannot benefit from a high-capacity source of electrical energy such as a car battery or from a mains connection.

Par ailleurs, la demande FR 2 935 518 A1 décrit un dispositif antivol pour article de maroquinerie ou analogue, notamment de type sac ou valise, comprenant un module externe équipé d'un émetteur RFID, destiné à être porté par l'utilisateur, et un module interne notamment équipé d'un récepteur RFID et d'un terminal de communication adapté à signaler le vol de l'article, en communiquant avec un autre terminal via un réseau de télécommunications. Cette demande ne prévoit pas de solution de secours au cas où le réseau de télécommunications serait indisponible, inopérant ou insuffisamment précis.Moreover, the demand FR 2 935 518 A1 describes an anti-theft device for leather goods or the like, in particular of the bag or suitcase type, comprising an external module equipped with an RFID transmitter, intended to be worn by the user, and an internal module notably equipped with an RFID receiver and a communication terminal suitable for reporting the theft of the article, by communicating with another terminal via a telecommunications network. This request does not provide for a back-up solution in the event that the telecommunications network is unavailable, inoperative or insufficiently precise.

Par conséquent, il subsiste un besoin pour bénéficier d'un moyen permettant de lutter contre le vol d'objets de faibles dimensions tels que des paquets de cigarettes.Consequently, there remains a need to benefit from a means making it possible to fight against the theft of objects of small dimensions such as packets of cigarettes.

L'invention est définie par les revendications. Elle vise à répondre à ce besoin et elle y parvient grâce à un dispositif de géolocalisation, comportant :

  • un récepteur d'un signal émis par un émetteur local, opérant sur une première plage de fréquences, de préférence une fréquence Bluetooth,
  • un émetteur opérant sur une deuxième plage de fréquences, de préférence un émetteur UNB (bande ultra étroite ou "Ultra Narrow Band"),
  • un moyen de géolocalisation, comportant une puce GPS, un accéléromètre, et
  • un circuit de contrôle agencé pour :
    • détecter la sortie du dispositif du champ de l'émetteur local,
    • activer l'émetteur du dispositif en cas de sortie du champ de l'émetteur local et transmettre via l'émetteur du dispositif la position du dispositif telle que déterminée par le moyen de géolocalisation, et
    • en cas de présence dans le champ de l'émetteur local, maintenir le dispositif dans un état de veille où la consommation électrique est réduite. En outre, selon l'invention, le dispositif de géolocalisation est adapté pour passer en état d'alerte statique, ou en état d'alerte dynamique, dans les conditions décrites à la revendication 1.
The invention is defined by the claims. It aims to meet this need and it achieves this thanks to a geolocation device, comprising:
  • a receiver of a signal emitted by a local transmitter, operating on a first range of frequencies, preferably a Bluetooth frequency,
  • a transmitter operating on a second frequency range, preferably an UNB transmitter (ultra narrow band or "Ultra Narrow Band"),
  • a means of geolocation, comprising a GPS chip, an accelerometer, and
  • a control circuit designed for:
    • detect the exit of the device from the field of the local transmitter,
    • activate the transmitter of the device in the event of leaving the field of the local transmitter and transmit via the transmitter of the device the position of the device as determined by the geolocation means, and
    • if present in the field of the local transmitter, keep the device in a standby state where power consumption is reduced. Furthermore, according to the invention, the geolocation device is suitable for switching to a static alert state, or a dynamic alert state, under the conditions described in claim 1.

La largeur de bande en émission UNB est classiquement inférieure à 100 Hz, ce qui accroît la portée à puissance équivalente. De préférence, l'émetteur du dispositif est dans l'UHF (entre 300 MHz et 3 GHz), notamment sur la fréquence 868 MHzThe UNB transmission bandwidth is conventionally less than 100 Hz, which increases the range at equivalent power. Preferably, the transmitter of the device is in the UHF (between 300 MHz and 3 GHz), in particular on the 868 MHz frequency

Le dispositif peut également comporter un émetteur VHF, permettant de communiquer sur une bande de fréquences de 30 MHz à 300 MHz, exploitée aujourd'hui par des terminaux VHF existants chez les forces de l'ordre et apportant une aide complémentaire pour localiser l'objet dans les derniers mètres.The device can also include a VHF transmitter, making it possible to communicate on a frequency band from 30 MHz to 300 MHz, used today by existing VHF terminals at the police and providing additional help to locate the object. in the last few meters.

Le dispositif selon l'invention peut également comporter une puce de téléphonie mobile. Dans ce cas, le circuit de contrôle peut être agencé pour activer la puce de téléphonie mobile en cas de sortie du champ de l'émetteur local et transmettre via cette puce la position du dispositif telle que déterminée par le moyen de géolocalisation.The device according to the invention can also include a mobile telephone chip. In this case, the control circuit can be arranged to activate the mobile telephone chip in the event of leaving the field of the local transmitter and to transmit via this chip the position of the device as determined by the geolocation means.

Le réseau de téléphonie mobile peut être de type GSM ou tout autre norme de technologie de téléphonie mobile, UMTS, LTE, etc.The mobile telephony network can be of the GSM type or any other standard of mobile telephony technology, UMTS, LTE, etc.

Le circuit de contrôle peut être agencé pour sélectionner l'émission soit sur le réseau de téléphonie mobile soit sur le réseau de l'émetteur du dispositif, selon la disponibilité de ces réseaux. La sélection peut encore s'effectuer selon le besoin des personnes à la recherche de l'objet volé. Ainsi, le réseau à sélectionner en premier peut être prédéfini, et l'autre réseau n'est sélectionné par le dispositif que si le premier est indisponible, inopérant ou insuffisamment précis.The control circuit can be arranged to select the transmission either on the mobile telephone network or on the network of the transmitter of the device, depending on the availability of these networks. The selection can still be made according to the needs of those looking for the stolen object. Thus, the network to be selected first can be predefined, and the other network is selected by the device only if the first is unavailable, inoperative or insufficiently precise.

Dans l'état de veille, ou dans l'état d'alerte mais en présence du réseau de l'émetteur, la puce de téléphonie mobile peut rester inactive, pour limiter la consommation électrique.In the standby state, or in the alert state but in the presence of the transmitter network, the mobile telephone chip can remain inactive, to limit power consumption.

De préférence, le dispositif est dissimulé à l'intérieur d'un emballage, qui peut être un étui d'un faux paquet de cigarettes.Preferably, the device is concealed within a package, which may be a case of a fake pack of cigarettes.

L'invention offre une solution simple et efficace pour lutter contre le vol d'objets tels que des paquets de cigarettes.The invention offers a simple and effective solution for combating the theft of objects such as cigarette packs.

En effet, le dispositif peut être fabriqué avec un encombrement réduit et présenter une très faible consommation électrique, et ainsi peut être facilement disposé dans un faux étui de cigarettes et rester en veille pendant une très longue période.Indeed, the device can be manufactured with a small footprint and have a very low power consumption, and thus can be easily placed in a fake cigarette case and remain on standby for a very long period.

L'émission en UNB permet une consommation très basse.The emission in UNB allows a very low consumption.

Les données émises sont par exemple sous forme de messages de moins de 100 octets, par exemple de 12 octets, avec par exemple un plafond à 150 messages par jour.The data transmitted is for example in the form of messages of less than 100 bytes, for example of 12 bytes, with for example a ceiling of 150 messages per day.

Il est particulièrement avantageux que le dispositif comporte un accéléromètre, comme expliqué plus loin. Cet accéléromètre peut accroître la précision de la localisation et/ou servir à d'autres fonctions.It is particularly advantageous for the device to include an accelerometer, as explained below. This accelerometer can increase the accuracy of the localization and / or be used for other functions.

Le dispositif peut également comporter divers autres capteurs tels qu'un capteur de luminosité, de température, et/ou de pression.The device can also include various other sensors such as a light, temperature, and / or pressure sensor.

L'invention a encore pour objet, selon un autre de ses aspects, un procédé d'aide à la récupération d'objets volés, comportant les étapes consistant à :

  • installer dans le champ d'un émetteur local un dispositif selon l'invention, et
  • en cas de sortie du dispositif du champ de l'émetteur local et d'émission de données de géolocalisation par le dispositif, acheminer ces données à un terminal client.
Another subject of the invention, according to another of its aspects, is a method of aid in the recovery of stolen objects, comprising the steps consisting in:
  • install in the field of a local transmitter a device according to the invention, and
  • in the event of the device leaving the field of the local transmitter and sending geolocation data by the device, forward this data to a client terminal.

Les données de géolocalisation peuvent transiter via un serveur d'un réseau M2M tel qu'un réseau SIGFOX ou LORA.Geolocation data can pass through a server in an M2M network such as a SIGFOX or LORA network.

Le dispositif peut être caché dans un emballage au milieu d'autres emballages similaires de produits authentiques. Cet emballage peut être un étui de cigarettes.The device may be hidden in a package among other similar packages of genuine products. This packaging can be a cigarette case.

La présence d'un accéléromètre dans le dispositif permet de l'utiliser pour détecter un mouvement du dispositif. Il est alors possible de passer d'un état de veille à un état d'alerte où les données de localisation sont émises, à la double condition d'une perte de réception du signal de l'émetteur local et d'un mouvement du dispositif avant ou après la perte de réception dans un intervalle de temps prédéfini.The presence of an accelerometer in the device enables it to be used to detect movement of the device. It is then possible to go from a standby state to an alert state where the location data is transmitted, on the double condition of a loss of reception of the signal from the local transmitter and of a movement of the device. before or after the loss of reception within a predefined time interval.

La présence d'un accéléromètre peut être utile également pour accroître la précision de la localisation.The presence of an accelerometer can also be useful to increase the accuracy of the location.

Les données de localisation peuvent être émises à une fréquence différente selon que le dispositif détermine qu'il est en mouvement ou non, grâce à l'accéléromètre le cas échéant. Par exemple, lorsque le dispositif est en mouvement, la fréquence d'émission des données de localisation peut être de 1s à plusieurs minutes selon la programmation du système.The location data can be transmitted at a different frequency depending on whether the device determines it is moving or not, using the accelerometer if necessary. For example, when the device is in motion, the location data transmission frequency can be from 1s to several minutes depending on the programming of the system.

Le dispositif peut être agencé pour prendre au moins un état de veille et au moins un état d'alerte.The device can be arranged to take at least one standby state and at least one alert state.

Dans l'état de veille, la consommation électrique est réduite au mieux, et le moyen de localisation peut être désactivé.In the standby state, power consumption is reduced at best, and the locating means can be deactivated.

Dans l'état d'alerte, le dispositif transmet des données de localisation.In the alert state, the device transmits location data.

Il peut s'avérer avantageux que le dispositif puisse passer d'un état d'alerte dynamique, où il est en mouvement avec le moyen de localisation activé, et transmet des données de localisation, à un état d'alerte statique où il est immobile et désactive le moyen de localisation afin de préserver la source d'énergie. La sortie de l'état d'alerte statique vers l'état d'alerte dynamique peut se faire grâce à l'accéléromètre.It may be advantageous for the device to be able to pass from a dynamic alert state, where it is in motion with the locating means activated, and transmits location data, to a static alert state where it is stationary. and deactivates the locating means in order to preserve the energy source. The exit from the static alert state to the dynamic alert state can be done using the accelerometer.

On a représenté à la figure 1 un exemple de dispositif 10 selon l'invention. Celui-ci comporte un circuit électronique qui peut être logé dans un boîtier 12 en matière plastique.We represented at the figure 1 an example of a device 10 according to the invention. This comprises an electronic circuit which can be housed in a housing 12 made of plastic.

Dans un exemple de mise en œuvre de l'invention, le dispositif 10 est destiné à la lutte contre le vol de cigarettes et le boîtier 12 est agencé pour se loger dans un emballage 13 imitant l'apparence d'un étui de cigarettes authentique. Il peut s'agir d'un étui conditionné avec d'autres paquets en cartouche ou d'un étui individuel.In an exemplary implementation of the invention, the device 10 is intended for combating the theft of cigarettes and the housing 12 is arranged to be housed in a packaging 13 imitating the appearance of an authentic cigarette case. This may be a case packaged with other cartridge packs or an individual case.

Le dispositif 10 comporte, comme illustré sur la figure 2, un circuit de contrôle 20 tel qu'un microcontrôleur par exemple, et un certain nombre de composants périphériques tels qu'un émetteur/récepteur 22 opérant à une première fréquence f1, un émetteur/récepteur 21 opérant à une deuxième fréquence f2, une puce de téléphonie mobile 35 et une puce GNSS de localisation par satellites 23, de préférence une puce GPS.The device 10 comprises, as illustrated in figure 2 , a control circuit 20 such as a microcontroller for example, and a certain number of peripheral components such as a transmitter / receiver 22 operating at a first frequency f1, a transmitter / receiver 21 operating at a second frequency f2, a chip of mobile telephony 35 and a GNSS satellite positioning chip 23, preferably a GPS chip.

L'ensemble est alimenté par une source d'énergie 24 telle qu'une ou plusieurs piles, rechargeables ou non, via un éventuel régulateur de tension. Un adaptateur externe peut, le cas échéant, être connecté temporairement au dispositif 10 pour recharger la source d'énergie 24 ou permettre de tester son fonctionnement sans solliciter la source 24.The assembly is powered by an energy source 24 such as one or more batteries, rechargeable or not, via a possible voltage regulator. An external adapter can, where appropriate, be temporarily connected to the device 10 to recharge the energy source 24 or allow its operation to be tested without requesting the source 24.

Dans l'exemple illustré, le microcontrôleur 20 échange des données avec une mémoire 27 qui contient le système d'exploitation.In the example illustrated, the microcontroller 20 exchanges data with a memory 27 which contains the operating system.

Un algorithme implémenté dans le microcontrôleur 20 peut permettre de sélectionner l'émission des données sur le réseau de téléphonie mobile en activant la puce 35, dans le cas où le réseau de l'émetteur/récepteur 21 serait indisponible, inopérant ou insuffisamment précis. Cet algorithme donne à la personne en quête de l'objet égaré la possibilité de sélectionner par elle-même le réseau d'émission.An algorithm implemented in the microcontroller 20 can make it possible to select the transmission of data on the mobile telephone network by activating the chip 35, in the event that the network of the transmitter / receiver 21 is unavailable, inoperative or insufficiently precise. This algorithm gives to the person in search of the lost object the possibility of selecting for himself the emission network.

Le dispositif 10 peut comporter un bus de test de type JTAG.The device 10 can include a JTAG type test bus.

Un ou plusieurs indicateurs lumineux tels que des LEDs peuvent signaler l'état de fonctionnement du dispositif 10.One or more light indicators such as LEDs can indicate the operating state of the device 10.

Le dispositif 10 comporte avantageusement un accéléromètre 26.The device 10 advantageously comprises an accelerometer 26.

L'émetteur / récepteur 21 est destiné à émettre, entre autres, des données de géolocalisation fournies par la puce 23 à un réseau 30, comme illustré sur la figure 3. Ce réseau 30 achemine les données à un terminal client 32, à disposition des forces de l'ordre par exemple.The transmitter / receiver 21 is intended to transmit, among other things, geolocation data supplied by the chip 23 to a network 30, as illustrated in FIG. figure 3 . This network 30 routes the data to a client terminal 32, available to law enforcement, for example.

L'émetteur / récepteur 21 est agencé dans l'exemple illustré pour utiliser un réseau UNB à 868 MHz, 902 ou 928 MHz tel que le réseau M2M SIGFOX ou LORA. Un tel réseau est plus économique à utiliser qu'un réseau de téléphonie mobile de type GSM, ce qui facilite la mise en œuvre de l'invention à une large échelle.The transmitter / receiver 21 is arranged in the example illustrated to use an UNB network at 868 MHz, 902 or 928 MHz such as the M2M SIGFOX or LORA network. Such a network is more economical to use than a GSM type mobile telephone network, which facilitates the implementation of the invention on a large scale.

Un tel réseau comporte une pluralité d'antennes 34 implantées sur l'ensemble d'un territoire. Un serveur 36 permet de transmettre des données reçues sur ce réseau à un destinataire dont l'adresse lui a été communiquée, via une interconnexion au réseau Internet 37 par exemple.Such a network comprises a plurality of antennas 34 located over the whole of a territory. A server 36 makes it possible to transmit data received on this network to a recipient whose address has been communicated to it, via an interconnection to the Internet network 37 for example.

L'émetteur / récepteur 21 est par exemple un module SI 868 25 MW de référence ARF7764AA.The transmitter / receiver 21 is for example an SI 868 25 MW module with reference ARF7764AA.

La transmission des données peut comporter la répétition des messages plusieurs fois, par exemple trois fois, avec un délai de l'ordre de 1s entre les envois.The transmission of data may include the repetition of the messages several times, for example three times, with a delay of the order of 1 s between transmissions.

En cas de réception de données provenant du réseau 30, celles-ci le sont dans une fenêtre temporelle prédéfinie après l'envoi du premier message, cette fenêtre étant de 20s dans le cas du réseau SIGFOX.If data is received from network 30, they are received in a predefined time window after sending the first message, this window being 20 s in the case of the SIGFOX network.

Le dispositif 10 peut être identifié par le réseau 30 grâce à un identifiant intégré à la fabrication de l'émetteur / récepteur 21.The device 10 can be identified by the network 30 by virtue of an identifier integrated into the manufacture of the transmitter / receiver 21.

L'émetteur / récepteur 22 est destiné à recevoir un signal d'un émetteur local 40.The transmitter / receiver 22 is intended to receive a signal from a local transmitter 40.

L'émetteur / récepteur 22 est par exemple un émetteur / récepteur Bluetooth à basse consommation, encore appelé « Bluetooth low energy » et l'émetteur / récepteur local 40 un émetteur Bluetooth local présent uniquement sur le lieu d'achat ou de stockage des produits que l'on souhaite protéger. Cet émetteur / récepteur 40 est par exemple de type Beacon BLE, ce qui correspond à la version V4.0 BLUETOOTH.The transmitter / receiver 22 is for example a low-consumption Bluetooth transmitter / receiver, also called “Bluetooth low energy” and the local transmitter / receiver 40 a local Bluetooth transmitter present only at the place of purchase or storage of the products. that we want to protect. This transmitter / receiver 40 is for example of the Beacon BLE type, which corresponds to the BLUETOOTH version V4.0.

La portée du signal émis par l'émetteur local est ainsi typiquement inférieure à 40m.The range of the signal emitted by the local transmitter is thus typically less than 40m.

Le signal émis par l'émetteur / récepteur local 40 est un signal numérique codé, de sorte que l'on évite toute interférence susceptible de tromper le dispositif 10 quant à la sortie effective du champ de l'émetteur local 40.The signal emitted by the local transmitter / receiver 40 is a coded digital signal, so that any interference which could deceive the device 10 as to the effective exit of the field of the local transmitter 40 is avoided.

Le dispositif 10 peut prendre au moins deux états de fonctionnement.The device 10 can take at least two operating states.

Un premier état correspond à un mode d'attente ou de veille, dans lequel on cherche à minimiser la consommation électrique de façon à prolonger au mieux la durée de vie de la source d'énergie 24. L'autonomie recherchée en état de veille est avantageusement supérieure à 8 mois, mieux à 12 mois.A first state corresponds to a standby or standby mode, in which an attempt is made to minimize the electrical consumption so as to best extend the life of the energy source 24. The autonomy sought in the standby state is advantageously greater than 8 months, better than 12 months.

Dans le mode de veille, l'émetteur / récepteur 21 est inactif ou en activité réduite, c'est-à-dire qu'il ne transmet au réseau 30 aucune donnée de localisation ; il est possible de ne transmettre aucune donnée, quelle qu'elle soit ; en variante, les données transmises peuvent se limiter à des données signalant que le dispositif est toujours en état de fonctionner. Par exemple, ces données peuvent coder l'état de charge de la source d'énergie 24. La fréquence d'émission de ces données peut être supérieure à 1 jour, mieux à 10 jours. Les données transmises peuvent l'être sous un format signalant l'état de veille du dispositif ; un identifiant du dispositif 10 est émis, de façon à attribuer les données reçues au bon dispositif. Le récepteur de l'émetteur / récepteur 21 peut être totalement inactif dans cet état de veille.In the standby mode, the transmitter / receiver 21 is inactive or in reduced activity, that is to say it does not transmit to the network 30 any location data; it is possible not to transmit any data whatsoever; alternatively, the data transmitted may be limited to data indicating that the device is still in working order. For example, these data can code the state of charge of the energy source 24. The transmission frequency of these data can be greater than 1 day, better still 10 days. The data transmitted may be in a format indicating the standby state of the device; an identifier of the device 10 is sent, so as to attribute the data received to the correct device. The receiver of the transmitter / receiver 21 may be completely inactive in this standby state.

En mode veille, l'émetteur /récepteur 22 peut n'émettre aucune donnée à destination de l'émetteur / récepteur local 40, se contentant de détecter sa présence ; il est ainsi possible de n'utiliser qu'un récepteur au lieu d'un émetteur / récepteur 22. En variante, l'émetteur/ récepteur 22 échange des données avec un réseau local dont fait partie l'émetteur local 40, ce qui permet par exemple à l'utilisateur de paramétrer à distance le dispositif 10 via un micro-ordinateur connecté à un réseau local et/ou de le rendre opérationnel.In standby mode, the transmitter / receiver 22 can send no data to the local transmitter / receiver 40, merely detecting its presence; it is thus possible to use only one receiver instead of a transmitter / receiver 22. In variant, the transmitter / receiver 22 exchanges data with a local network of which the local transmitter 40 is a part, which for example allows the user to remotely configure the device 10 via a microcomputer connected to a local network and / or make it operational.

Le dispositif 10 peut aussi passer dans un état d'alerte dynamique, lorsqu'il est en mouvement, ou statique, lorsqu'il est immobile.The device 10 can also go into a dynamic alert state, when it is in motion, or static, when it is stationary.

Le passage dans cet état d'alerte est déclenché par la perte de détection de l'émetteur local 40.The transition to this alert state is triggered by the loss of detection of the local transmitter 40.

Pour assurer cette détection tout en maintenant la consommation électrique à une valeur aussi basse que possible, la détection de la perte du signal de l'émetteur 40 peut ne pas être permanente mais être effectuée de façon périodique, par exemple à des intervalles de temps allant de 1h à 24h.To ensure this detection while keeping the power consumption as low as possible, the detection of the loss of the signal from the transmitter 40 may not be permanent but may be carried out periodically, for example at time intervals ranging from from 1 hour to 24 hours.

De préférence, afin d'éviter de passer intempestivement en mode d'alerte en cas de coupure accidentelle de l'émetteur local suite à une coupure de courant par exemple, le passage en mode d'alerte peut s'effectuer à la double condition d'une part de perte de l'émetteur local 40 et d'autre part de détection d'un mouvement par l'accéléromètre depuis un moment suffisamment reculé dans le temps où le champ de l'émetteur local était détecté.Preferably, in order to avoid inadvertently switching to alert mode in the event of an accidental cut-off of the local transmitter following a power cut, for example, switching to alert mode can be carried out under the double condition of 'on the one hand loss of the local transmitter 40 and on the other hand detection of a movement by the accelerometer from a sufficiently far back in time when the field of the local transmitter was detected.

Ainsi, en cas de perte temporaire de l'émetteur local sans détection de mouvement associée, le dispositif peut rester en état de veille. Par contre, si la perte de l'émetteur s'est accompagnée d'un mouvement, le dispositif peut passer en mode d'alerte.Thus, in the event of temporary loss of the local transmitter without associated movement detection, the device can remain in the standby state. On the other hand, if the loss of the transmitter was accompanied by a movement, the device can go into alert mode.

En état d'alerte, la puce 23 peut être activée, et des données de géolocalisation transmises au dispositif de contrôle 20, où elles peuvent être mémorisées et/ou transmises via le réseau 30 au terminal client, ou stockées sur un serveur distant consultable ensuite par les forces de l'ordre par exemple.In an alert state, the chip 23 can be activated, and geolocation data transmitted to the control device 20, where they can be stored and / or transmitted via the network 30 to the client terminal, or stored on a remote server which can then be consulted. by the police, for example.

La fréquence de transmission des données de géolocalisation au réseau 30 peut s'opérer selon une loi prédéfinie, afin de maximiser les chances d'interception des auteurs du vol.The frequency of transmission of the geolocation data to the network 30 can operate according to a predefined law, in order to maximize the chances of interception of the perpetrators of the theft.

En particulier, la fréquence d'émission est plus élevée tant que le dispositif 10 détecte qu'il est en mouvement.In particular, the transmission frequency is higher as long as the device 10 detects that it is in motion.

Lorsque le dispositif 10 ne détecte plus de mouvement, soit parce que l'accéléromètre délivre un signal qui peut être interprété comme tel, soit parce que la position donnée par la puce GPS n'évolue plus pendant une durée prédéfinie, par exemple d'au moins 15 minutes, le dispositif passe dans un état d'alerte statique et transmet des données signalant son état immobile, en plus de sa dernière position.When the device 10 no longer detects movement, either because the accelerometer delivers a signal which can be interpreted as such, or because the position given by the GPS chip no longer changes for a predefined period, for example at least 15 minutes, the device goes into a static alert state and transmits data indicating its stationary state, in addition to its last position.

Pour économiser la source d'énergie 24, lorsque le dispositif 10 est dans l'état d'alerte statique, la puce GPS est désactivée afin de réduire la consommation électrique et la fréquence d'émission des données de localisation augmentée. Par exemple, la fréquence d'émission des données peut passer de 30s par 10 mns au passage du mode de veille au mode d'alerte dynamique à une fréquence de 1 ou plus par jour après 3 jours. Cette fréquence peut le cas échéant, encore augmenter avec le temps si aucun mouvement n'est détecté.To save the power source 24, when the device 10 is in the static alert state, the GPS chip is deactivated in order to reduce the power consumption and the frequency of transmission of the location data increased. For example, the data transmission frequency can change from 30s per 10 mins to the transition from standby mode to dynamic alert mode at a frequency of 1 or more per day after 3 days. This frequency may, if necessary, increase further over time if no movement is detected.

Le dispositif 10 reste dans cet état jusqu'à ce qu'un mouvement soit à nouveau détecté à l'aide de l'accéléromètre.The device 10 remains in this state until movement is again detected with the aid of the accelerometer.

Dans ce cas, le dispositif 10 repasse dans un état d'alerte dynamique et la puce 23 est réactivée pour transmettre des données de position.In this case, the device 10 returns to a dynamic alert state and the chip 23 is reactivated to transmit position data.

Le dispositif 10 peut être agencé pour détecter la perte du signal GPS de localisation par satellites alors que la puce 23 est activée. Dans ce cas, le dispositif 10 est avantageusement agencé pour le signaler, via l'emploi d'un code particulier dans les données émises.The device 10 can be arranged to detect the loss of the GPS satellite positioning signal while the chip 23 is activated. In this case, the device 10 is advantageously arranged to signal it, via the use of a particular code in the data transmitted.

Pour faciliter le repérage du dispositif 10 une fois les forces de l'ordre arrivées sur le lieu correspondant aux données de localisation transmises, le dispositif 10 peut être agencé pour réagir, en mode d'alerte, à la réception d'un signal de recherche émis par un système de repérage équipant les forces de l'ordre.To facilitate the location of the device 10 once the police have arrived at the place corresponding to the location data transmitted, the device 10 can be arranged to react, in alert mode, to the reception of a search signal. issued by a tracking system fitted to the police.

Ce signal est par exemple similaire à celui de l'émetteur local 40 et il peut être détecté par l'émetteur / récepteur 22. Le dispositif peut être agencé pour réagir à la détection de ce signal en renvoyant une valeur représentative de la force avec laquelle il est reçu ; l'émission par l'émetteur / récepteur peut se faire en continu de façon à faciliter un repérage précis par triangulation.This signal is for example similar to that of the local transmitter 40 and it can be detected by the transmitter / receiver 22. The device can be arranged to react to the detection of this signal by returning a value representative of the force with which it is received; the transmission by the transmitter / receiver can be done continuously so as to facilitate precise identification by triangulation.

Dans une variante, le dispositif 10 comporte un capteur de luminosité ; cela suppose que le dispositif ne soit placé dans un emballage complètement opaque. Le capteur de luminosité peut être utile pour faciliter le repérage du dispositif, en renseignant par exemple sur la présence de lumière artificielle dans le local où se trouve le dispositif.In a variant, the device 10 comprises a light sensor; this assumes that the device is not placed in a completely opaque packaging. The light sensor can be useful to facilitate the location of the device, for example by providing information on the presence of artificial light in the room where the device is located.

Le dispositif peut comporter un capteur de pression ; ce dernier peut fournir une information sur l'étage d'un immeuble dans lequel se trouve le local contenant le dispositif.The device may include a pressure sensor; the latter can provide information on the floor of a building in which the room containing the device is located.

Le dispositif peut encore comporter un capteur de température qui peut renseigner sur son lieu d'entreposage, notamment à l'extérieur ou à l'intérieur d'un bâtiment.The device may also include a temperature sensor which can provide information on its storage location, in particular outside or inside a building.

Les informations provenant du capteur de luminosité et/ou de pression et/ou de température peuvent être transmises au réseau 30 quand le dispositif est en mode d'alerte statique par exemple, ou lorsque le dispositif a capté le signal de recherche utilisé pour le retrouver.The information coming from the light and / or pressure and / or temperature sensor can be transmitted to the network 30 when the device is in static alert mode for example, or when the device has picked up the search signal used to find it. .

Bien que le circuit de contrôle 20 soit, dans l'exemple qui vient d'être décrit, un microcontrôleur, celui-ci peut être remplacé, ainsi que ses composants périphériques, par tout autre circuit adapté à réaliser les fonctions recherchées. On peut ainsi utiliser tout autre circuit numérique à microprocesseur, réseau logique programmable, ASIC, ...Although the control circuit 20 is, in the example which has just been described, a microcontroller, it can be replaced, as well as its peripheral components, by any other circuit suitable for performing the desired functions. It is thus possible to use any other digital microprocessor circuit, programmable logic network, ASIC, etc.

Certains composants qui sont périphériques sur la figure 2 peuvent être intégrés au circuit de contrôle 20 sous la forme d'une puce unique multifonction.Some components that are peripheral on the figure 2 can be integrated into the control circuit 20 in the form of a single multifunction chip.

La puce GPS peut être remplacée par tout autre moyen de géolocalisation par satellites, et la constellation de satellites peut être GALILEO ou toute autre constellation.The GPS chip can be replaced by any other means of geolocation by satellites, and the constellation of satellites can be GALILEO or any other constellation.

L'émetteur / récepteur 21 peut être remplacé par un émetteur seul. La fréquence f1 peut être autre que la bande 868 MHz.The transmitter / receiver 21 can be replaced by a single transmitter. The frequency f1 can be other than the 868 MHz band.

De même, l'émetteur / récepteur 22 peut être remplacé par un récepteur seul. La fréquence f2 peut être autre que la bande 2,4 GHz.Likewise, the transmitter / receiver 22 can be replaced by a single receiver. The frequency f2 can be other than the 2.4 GHz band.

Le dispositif 10 peut être équipé d'un microphone, le cas échéant, afin de lui permettre d'enregistrer les bruits dans son voisinage dans une mémoire, en mode d'alerte ou d'écouter un échange vocal.The device 10 can be equipped with a microphone, if necessary, in order to allow it to record the noises in its vicinity in a memory, in alert mode or to listen to a voice exchange.

Le dispositif 10 peut également être muni d'un haut-parleur, le cas échéant, lui permettant de prendre en mains le dispositif à distance et émettre une instruction vocale.The device 10 can also be provided with a loudspeaker, if necessary, allowing it to take control of the device remotely and to issue a voice instruction.

Bien que le dispositif 10 convienne tout particulièrement à la recherche d'objets volés, il peut encore s'appliquer à la recherche d'animaux domestiques, équipant le collier d'un chien par exemple, ou de personnes à la mémoire déficiente, tels que des patients atteints de la maladie d'Alzheimer. Dans ce cas, le haut-parleur peut permettre à une personne à distance de guider la personne égarée, la rassurer ou déclencher une intervention.Although the device 10 is particularly suitable for the search for stolen objects, it can still be applied to the search for domestic animals, equipping the collar of a dog, for example, or of people with poor memory, such as patients with Alzheimer's disease. In this case, the loudspeaker can allow a remote person to guide the lost person, reassure him or trigger an intervention.

Le dispositif peut encore équiper un véhicule de tout type.The device can also be fitted to a vehicle of any type.

Pour faciliter son utilisation, le dispositif peut à sa première mise en marche écouter les émetteurs locaux et s'appairer automatiquement à celui de plus forte intensité ; en variante, le choix de l'émetteur local est paramétré à l'aide d'un ordinateur connecté au dispositif.To facilitate its use, the device can listen to the local transmitters when it is first switched on and automatically pair with the higher intensity one; as a variant, the choice of the local transmitter is configured using a computer connected to the device.

Dans une variante, le dispositif est équipé d'un émetteur sonore ou visuel, qui est par exemple activé à distance par le signal de repérage, voire un moyen de synthèse vocale qui peut diffuser un message préenregistré ou transmis par l'intermédiaire du signal de repérage.In a variant, the device is equipped with a sound or visual transmitter, which is for example activated remotely by the location signal, or even a voice synthesis means which can broadcast a prerecorded message or transmitted via the signal from spotting.
