    专利说明:

    [0001] The present invention relates to devices and methods for assisting in the retrieval of stolen objects.
    [0002] The invention is particularly but not exclusively concerned with a solution for finding stolen cigarette packages. Vehicle-based antitheft systems are known, comprising a geolocation means and a transmitter for transmitting geolocation data to a mobile telephone network. The system is activated via the telephone network in case of theft. Such a system is relatively complex and expensive and requires to be connected to the vehicle battery in the waking state. It is not suitable for the protection of objects that can not benefit from a high-capacity electrical power source such as a car battery or a mains connection.
    [0003] Therefore, there remains a need for a means to combat the theft of small objects such as cigarette packs. The invention aims to meet this need and it achieves this through a geolocation device, comprising: a receiver of a signal transmitted by a local transmitter, operating on a first frequency range, preferably a Bluetooth frequency, a transmitter operating on a second frequency range, preferably an Ultra narrow band (UNB) transmitter, a geolocation means, preferably a GNSS satellite location chip such as a GPS chip, and a control circuit arranged to: detect the output of the device from the field of the local transmitter; activate the transmitter of the device in case of exit from 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 there is a presence in the field of the local transmitter, keep the device in a standby state where the power consumption is reduced ollowing.
    [0004] 3035225 2 The UNB transmit bandwidth is typically less than 100 Hz, which increases the range to equivalent power. Preferably, the transmitter is in the UHF (between 300 MHz and 3 GHz). Preferably, the device is concealed within a package, which may be a holster of a fake cigarette package. The invention offers a simple and effective solution to fight against theft of objects such as cigarette packs. 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 idle for a very long time. The emission in UNB allows a very low consumption. The transmitted data are for example in the form of messages of less than 100 bytes, for example 12 bytes, with for example a ceiling of 150 messages per day. It is particularly advantageous that the device comprises an accelerometer, as explained below. This accelerometer can increase the accuracy of the location and / or serve other functions. The device may also include various other sensors such as a sensor of brightness, temperature, and / or pressure. The invention further relates, in another of its aspects, to a method for assisting the recovery of stolen objects, comprising the steps of: - installing in the field of a local transmitter a device according to the invention, and - in case of the device of the output of the field of the local transmitter and transmission of geolocation data by the device, route these data to a client terminal. The geolocation data may transit via a server of an M2M network such as a SIGFOX or LORA network. The device may be hidden in a package in the middle of other similar packages of genuine products. This package can be a cigarette case. In the presence of an accelerometer in the device, it can be used to detect a movement of the device. It is then possible to switch from a standby state to a state of alert where the location data is transmitted, on the dual condition of a loss of reception of the signal from the local transmitter and a movement of the signal. device before or after receiving loss in a predefined time interval.
    [0005] 3035225 3 The presence of an accelerometer can be useful also to increase the precision of the localization. The location data may be transmitted at a different frequency depending on whether the device determines that it is in motion or not, thanks to the accelerometer, if any. For example, when the device is in motion, the transmission frequency of the location data may be from 1s to several minutes depending on the programming of the system. The device can be arranged to take at least one standby state and at least one alert state.
    [0006] In the standby state, the power consumption is best reduced, and the locating means can be disabled. In the alert state, the device transmits location data. It may be advantageous for the device to be able to switch from a dynamic alert state, where it is in motion with the activated locating means, and to transmit location data, to a static alert state where it is immobile and disables the location means to preserve the power source. The output of the static alert state to the dynamic alert state can be done through the accelerometer. The invention will be better understood on reading the following detailed description, non-limiting examples of implementation thereof, and on examining the appended drawing, in which: FIG. schematically in perspective an exemplary device according to the invention, - Figure 2 is a block diagram of the device of Figure 1, and - Figure 3 illustrates an example of a global system in which can evolve the device according to the invention . FIG. 1 shows an exemplary device 10 according to the invention. This comprises an electronic circuit which can be housed in a plastic housing 12. In an exemplary implementation of the invention, the device 10 is intended for the fight against 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 . It may be a case packaged with other cartridge packs or an individual case.
    [0007] The device 10 comprises, as illustrated in FIG. 2, a control circuit 20 such as a microcontroller for example, and a certain number of peripheral components such as a transmitter / receiver 21 operating at a first frequency f 1, a transceiver 22 operating at a second frequency f2, and a satellite location GNSS chip 23, preferably a GPS chip. The assembly is powered by a power source 24 such as one or more batteries, rechargeable or not, via a possible voltage regulator. An external adapter may, if necessary, be temporarily connected to the device 10 to recharge the power source 24 or to test its operation without soliciting the source 24.
    [0008] In the illustrated example, the microcontroller 20 exchanges data with a memory 27 which contains the operating system. The device 10 may comprise a JTAG type test bus. One or more light indicators such as LEDs can signal the operating status of the device 10.
    [0009] The device 10 advantageously comprises an accelerometer 26. The transmitter / receiver 21 is intended to transmit, among other things, geolocation data provided by the chip 23 to a network 30, as illustrated in FIG. 3. This network 30 carries the data to a client terminal 32, available to the forces of order for example.
    [0010] The transceiver 21 is arranged in the illustrated example to use an 868 MHz, 902 or 928 MHz UNB network such as the M2M SIGFOX or LORA network. Such a network is more economical to use than a mobile telephone network of GSM type, which facilitates the implementation of the invention on a large scale. Such a network comprises a plurality of antennas 34 implanted on the whole 25 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. The transmitter / receiver 21 is for example a reference SI 868 25 MW module ARF7764AA.
    [0011] The transmission of the data may comprise the repetition of the messages several times, for example three times, with a delay of the order of ls between the transmissions.
    [0012] When receiving data from the network 40, they are in a predefined time window after sending the first message, this window being 20s in the case of the SIGFOX network. The device 10 can be identified by the network 40 by virtue of an identifier integrated in the manufacture of the transmitter / receiver 21. The transmitter / receiver 22 is intended to receive a signal from a local transmitter 40. The transmitter / receiver receiver 22 is for example a low-power Bluetooth transmitter / receiver, also called "Bluetooth low energy" and the local transmitter 40 a 10 local Bluetooth transmitter present only at the place of purchase or storage of the products you want protect. This transmitter is for example Beacon BLE type, which corresponds to version V4.0 BLUETOOTH. The range of the signal emitted by the local transmitter is thus typically less than 40m.
    [0013] The signal transmitted by the local transmitter 40 is a coded digital signal, so that any interference likely to deceive the device 10 as to the effective output of the field of the local transmitter 40 is avoided. The device 10 can take at least two operating states. A first state corresponds to a standby or standby mode, in which it is sought to minimize the power consumption so as to prolong the life of the energy source 24 as much as possible. The autonomy sought in the standby state is advantageously greater than 8 months, better at 12 months. In the standby mode, the transmitter / receiver 21 is inactive or in reduced activity, that is to say that it transmits to the network 30 no location data; it is possible to transmit no data of any kind; alternatively, the transmitted data may be limited to data indicating that the device is still in working order. For example, these data can encode the state of charge of the energy source 24. The transmission frequency of these data can be greater than 1 day, better 10 days. The transmitted data may be in a format indicating the idle state of the device; an identifier of the device 10 is transmitted, so as to allocate the received data to the correct device. The receiver of the transceiver 21 can be totally inactive in this state of standby.
    [0014] In standby mode, the transmitter / receiver 22 may transmit no data to the local transmitter 40, merely detecting its presence; it is thus possible to use only one transmitter instead of a transmitter / receiver 22. In a variant, the transmitter / receiver 22 exchanges data with a local area network of which the local transmitter 40 is part, which allows for example the user to remotely set the device 10 via a microcomputer connected to a local network and / or make it operational. The device 10 can also go into a dynamic alert state, when it is in motion, or static, when it is stationary.
    [0015] The passage into this state of alert is triggered by the loss of detection of the local transmitter 40. To ensure this detection while keeping the power consumption as low as possible, the detection of the signal loss of the Transmitter 40 may not be permanent but may be performed periodically, for example at time intervals ranging from 1 hr to 24 hr. Preferably, in order to avoid accidentally switching to alert mode in case of accidental shutdown of the local transmitter following a power failure for example, the transition to alert mode can be performed under the dual condition of a part of the loss of the local transmitter 40 and secondly of detection of a movement by the accelerometer for a moment sufficiently back in time when the field of the local transmitter was detected. Thus, in the event of a temporary loss of the local transmitter without associated motion detection, the device can remain in a standby state. On the other hand, if the loss of the transmitter is accompanied by a movement, the device can go into alert mode.
    [0016] In the state of alert, 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 searchable remote server. then by the police for example. The frequency of transmission of the geolocation data to the network 30 can take place according to a predefined law, in order to maximize the chances of interception of the authors of the flight.
    [0017] In particular, the transmission frequency may be higher as long as the device 10 detects that it is moving. When the device 10 no longer detects movement, either because the accelerometer delivers a signal that 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 can go into a static alert state and transmit data indicating its stationary state, in addition to its last position. To save the power source 24, when the device 10 is in the static alert state, the GPS chip may be turned off to reduce the power consumption and the transmission frequency of the augmented location data. For example, the data transmission rate can be increased from 30s per 10mns from sleep mode to dynamic alert mode at a rate of 1 or more per day after 3 days. This frequency can, if necessary, increase with time if no movement is detected.
    [0018] Device 10 may remain in this state until motion is again detected using the accelerometer. In this case, the device 10 can return to a dynamic alert state and the chip 23 is reactivated to transmit position data. The device 10 may be arranged to detect the loss of the satellite location GPS 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. In order to facilitate the identification of the device 10 once the security forces have arrived at the location corresponding to the location data transmitted, the device 10 can be arranged to react, in alert mode, to the reception of a signal of search issued by a tracking system equipping the police. 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 he is received; transmission by the transmitter / receiver can be done continuously to facilitate accurate tracking by triangulation.
    [0019] In a variant, the device 10 comprises a brightness sensor; this assumes that the device is placed in a completely opaque package. The brightness sensor may be useful to facilitate the identification of the device, for example by informing about the presence of artificial light in the room where the device 5 is located. The device may comprise a pressure sensor; the latter can provide information on the floor of a building in which the room containing the device is located. The device may also include a temperature sensor that can provide information on its storage location, especially outside or inside a building. The information from the brightness and / or pressure sensor and / or temperature can be transmitted to the network 30 when the device is in static alert mode for example, or when the device has captured the search signal used to find it .
    [0020] Although the control circuit 20 is, in the example just described, a microcontroller, it can be replaced, as well as its peripheral components, by any other circuit adapted to perform the desired functions. It is thus possible to use any other microprocessor-based digital circuit, programmable logic array, ASIC. Some components which are peripheral in FIG. 2 can be integrated in the control circuit 20 in the form of a single multifunction chip. The GPS chip can be replaced by any other means of geolocation by satellites, and the satellite constellation can be GALILEO or any other constellation. The transmitter / receiver 21 can be replaced by a transmitter alone. The frequency f1 may be other than the 868 MHz band.
    [0021] Similarly, the transmitter / receiver 22 may be replaced by a single receiver. The frequency f2 may be other than the 2.4 GHz band. The device 10 can be made without accelerometer, if necessary. The device 10 may be devoid of housing and be housed directly in the packaging of one of the products that one seeks to protect.
    [0022] The device 10 may be equipped with a microphone, if necessary, to enable it to record noises in its vicinity in a memory, in alert mode.
    [0023] 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 people with poor memory, such as patients with Alzheimer's disease.
    [0024] The device can still equip a vehicle of any type. To facilitate its use, the device can at its first start listening to local transmitters and be automatically paired with the one of higher intensity; alternatively, the choice of the local transmitter is set using a computer connected to the device.
    [0025] In a variant, the device is equipped with a sound or visual transmitter, which is for example activated remotely by the registration signal, or even a voice synthesis device which can broadcast a prerecorded message or transmitted via the signal. locating. The device may or may not include an on / off switch as well as a connector such as a micro-USB, serial or other port that allows programming, setting or retrieve stored data. The M2M network can be replaced by any other network for routing the location data to the client terminal. The location data can be viewed on the client terminal in a variety of ways, for example using a Google Maps type interface. The device 10 may comprise a removable memory card such as a micro SD card or a SIM card. A telephony chip such as a GSM chip can be added to the device and activated in case of impossibility to access the network 30 for example. In this case, this chip can also be used to locate the device. In the standby state, or in the state of alert but in the presence of the network 30, the telephony chip can remain inactive, to limit the power consumption. The expression "comprising one" must be understood as being synonymous with "comprising at least one". 30
