Definitions
- the present invention relates to a system for automated inventory and an associated removable anti-theft electronic device.
- the invention finds particular interest in carrying out an automated inventory in premises containing a very large number of items, each equipped with a removable anti-theft electronic device, arranged on sales displays, or even storage halls.
- an electronic anti-theft device is called an electronic system intended to prevent and prevent theft. It comprises a badge or tag attached to a commercial item to be protected. This badge is separable from the article to be protected in order to be able to reuse it, and thus allow its attachment to a new article to be protected after the sale of the first article on which it was mounted.
- the use of these anti-theft devices is necessary in places of storage and presentation for the sale of items to be protected. When the items to be protected are presented for sale in a place, often a store, a consumer can seize them and custom provides that the consumer pays for it regularly at a checkout where the anti-theft device will be detached.
- Anti-theft tags equipped with a so-called passive UHF RFID technology chip are also known, which allow inventories to be taken in store, when a mobile RFID reader embedding a software solution capable of detecting an electromagnetic field produced by said RFID chip, also capable of counting the number of chips detected, is moved to the various store shelves.
- a mobile RFID reader embedding a software solution capable of detecting an electromagnetic field produced by said RFID chip, also capable of counting the number of chips detected, is moved to the various store shelves.
- This inventory operation therefore requires human intervention with a complete or partial scanning of the sales area and/or the reserve with a reader to read the articles, which, although faster compared to a traditional inventory with barcodes, can still seem tedious if the surface of the store is large and can cause some omissions to appear for lack of having gone through all the areas, or not counting all the items when there are too many juxtaposed tags.
- the store's stock is up to date only if the inventory counts are fairly close in time. It should be emphasized that store managers need the most recent stock information possible to better manage their sales activities and replenishment from the depot.
- the invention proposes to find a solution to this problem, in particular by offering an automated inventory solution, without human intervention, and without having to travel to the shelves, while guaranteeing the possibility of regular inventories over a long period of time.
- the advantage of the invention is to make it possible to secure and inventory items whose sales times can be very long, and with shelf-keeping times of several months or years, but also to be able to increase the operability anti-theft devices before they have to be repaired, even when they are used iteratively on successive articles to be protected.
- the invention relates to a system for an automated inventory of several items to be secured arranged in a room, each item being equipped with a removable anti-theft electronic device, the system comprising a detector at an exit from the room and a beacon disposed in the room, this beacon being provided with a wireless communication means, the anti-theft electronic device optionally comprising a detection means capable of being detected by the room detector, and further comprising
- this source can be a battery or an accumulator
- a removable fastening means capable of occupying two states relative to the article, a first locked and manually unremovable state of the article and a detached state of the article
- this state sensor being able to indicate a charge level of the energy source and/or a state of the fastening means
- a wireless control and communication unit capable of transmitting a signal comprising information relating to the article, this signal being intended to be read by the beacon, the device comprising a means of controlling the energy source, this control means making it possible to switch the energy source between 3 modes: off, on standby or active according to status information from the status sensor and an inventory frequency setpoint contained in the memory.
- the interest of the invention is to allow the activation, said passage in active mode of the energy source, when the fixing means is brought into a locked state relative to an article, and thus allow encoding of data relating to this article in the memory.
- This optimization of energy consumption improves the duration of use of the device and the possibility of implementing the automated inventory system.
- the wireless control and communication unit may comprise a near-field communication chip in a body and/or one end of the removable fastening means, the insertion of the end into a housing of the body bringing the securing means into a locked state.
- the locked state of the fixing means can be obtained with an anti-theft device of the clamp type formed of a single body or of the pin type, and in this case, the wireless control and communication unit is housed in this single body.
- the wireless communication and control unit may also be capable of transmitting a signal comprising status information provided by the status sensor.
- the system according to the invention can thus monitor an untimely change of state from locked to detached and synonymous with break-in, just as it can also detect a lowering of the level of the energy source and therefore of the ability of the device to allow said inventories.
- the system may include a software platform for receiving the data collected by the beacon and programming a frequency, a duration and/or a zoning of the readings performed by the beacon.
- the wireless control and communication unit can vary its transmission power according to a distance detected between the device and the beacon.
- the wireless control and communication unit may comprise a means of detecting the nearest beacon, in order to minimize the transmission power.
- the tighter the network of beacons on the sales area the more the transmission power of the wireless control and communication units can be reduced, and thus increase the life of the device, and limit the need to change, renew or recharging the power source.
- anti-theft devices according to the invention retained on items to be secured can each comprise a programmed clock to limit the number of means for controlling the energy source going into active status during the same time period.
- An advantage of this arrangement is to limit the number of signals emitted simultaneously by the various control and wireless communication units respectively of the various devices.
- the energy source can be recharged, and thus extend the operating time of the anti-theft device.
- a means for controlling the energy source may comprise an accelerometer in order to switch the energy source to the active mode when a value measured by the accelerometer exceeds a threshold.
- the energy source control means may include a motion and/or vibration detector.
- the invention also relates to a removable anti-theft electronic device optionally comprising a detection means capable of being detected by a detector of a room, and further comprising
- a removable fastening means capable of occupying two states relative to an article to be secured, a first locked and manually unremovable state of the article and a detached state of the article
- this state sensor being able to indicate a charge level of the energy source and/or a state of the fastening means
- the device comprises means for controlling the energy source , this control means making it possible to switch the energy source between 3 modes: off, on standby or active according to status information from the status sensor.
- the energy source control means can operate according to an inventory frequency setpoint contained in the memory, the wireless control and communication unit being capable of transmitting a signal comprising information relating to the item to be secured.
- the detection means can be separate from the wireless control and communication unit, and be passive.
- this detection means can be of the radiofrequency (standardized RF 8.2 MHz) or acousto-magnetic type.
- the wireless control and communication unit can emit a signal when the energy source is active.
- the wireless control and communication unit can operate according to the Bluetooth low energy protocol (BLE, Bluetooth Low Energy in English). In particular, this unit can communicate actively and bidirectionally at a frequency of 2.4GHz.
- BLE Bluetooth Low Energy in English
- the status information may relate to the current locked or detached state of the fastening means, and or relate to a number of changes of state of said fastening means from its initialization until the date of issue of the information.
- a change of state can be a sign of a break-in, it is possible to detect devices in a detached position which should not be, and or devices locked and probably detached from any article. It is thus possible to count the stolen items during an inventory by counting the number of active devices that are no longer linked to an item. This information also makes it possible to make an inventory of the number of anti-theft devices available in store to secure other items.
- the invention also relates to the assembly formed by an article to be secured and an anti-theft device according to the invention retained on this article, in which the means for controlling the energy source can allow to switch the mode of the energy source according to an inventory frequency setpoint contained in the memory of the device, this inventory frequency being a function of a threshold relating to a quality of said article, for example its market value.
- the invention also relates to a method for associating an article to be secured and a removable anti-theft device according to the invention comprising the following successive steps:
- the energy source control means switches the energy source to active mode for a duration t, the start of which begins at the end of the previous step,
- the energy source is switched to standby mode.
- the invention also relates to a method for dissociating an article to be secured and a removable anti-theft device held irremovably manually on this article, the device being according to the invention, and the dissociation process comprising the following successive steps:
- the energy source control means switches the energy source to active mode for a duration t, the start of which begins at the end of the previous step,
- the wireless control and communication unit transmits a signal comprising information relating to the article and to an identifier of the device, in particular in order to allow this data subsequently collected by the beacon to allow dissociation of these two pieces of information in the software platform,
- the energy source is switched to off or standby mode.
- This dissociation process makes it possible to verify the data collected with a view to an inventory.
- the inventory can thus be constructed subtractively with reference to a known situation, from which we remove the items dissociated.
- inventory can be designed additively, counting only items associated with a device.
- This dissociation process can also be effective to allow billing and sale at the right price of an item to be protected. Indeed, in addition to the price tag of the item, the device can thus allow an additional control of sales receipts.
