    GENERAL TECHNICAL AREA AND CONTEXT OF THE INVENTION
    The present invention relates generally to the management of electronic gondola labels distributed along a rail of a gondola of a sales area. More specifically, it is a question of determining the distribution of these electronic gondola labels, each of said electronic gondola labels being provided with an identifier specific to said electronic gondola label.
    In a sales area, such as in a supermarket, the electronic gondola labels are arranged along rails, said rails themselves being arranged along the outer ends of the shelves of the gondola. The electronic gondola labels are thus visible to consumers of the sales area, and communicate to them information relating to articles located in the immediate vicinity of these electronic gondola labels. Typically, the articles are located above or immediately below the associated electronic gondola label.
    The layout of a sales area is normally described by a planogram. A planogram is a set of association data between items of a sales area and locations of said sales area. The planogram establishes which items must be at such height, on which shelves and on how many linear meters. Preferably, a planogram takes the form of a visual representation of the location of a department or gondola in a sales area. It generally corresponds to a radius or linear seen from the front, but can also be visible in 3D on computer support.
    Ideally, the organization of the sales area and the planogram should reflect each other. However, the planograms currently used are theoretical visions of what the sales area should be. Indeed, they are typically defined generically, for a plurality of stores of similar size, for which the same layout and the same ridership is provided. Then, the layout of a given sales area is carried out on the basis of the theoretical planogram corresponding to the size of the sales area.
    In reality, the reality of the organization of the sales area deviates significantly from this theoretical planogram. Indeed, it is common that on the order of 10 to 15% of the items present in the sales area are not found on the planogram, for example because these items are specific to the sales area, and have not included in the planogram designed for a set of sales areas. In addition, the arrangement of the items in the sales area may vary over time, due to article shifts and adaptations made by the operators of the sales area, for example for seasonal items such as those offered only at Christmas or back to school.
    As a result, the planogram never conforms to reality, and a location of an electronic gondola label or of an article using this planogram suffers from the inability of the planogram to reflect reality. However, the inaccuracy of the planogram has other drawbacks, particularly in terms of inventory management and other commercial aspects, since the planogram is for example used to estimate the quantities of items on the gondolas, on the basis of the theoretical extent of their presence, which, erroneously, can lead to unexpected stock-outs.
    In the context of the management of the sales space, it is therefore very important to be able to determine the distribution of the electronic gondola labels along the rail, and in particular to ensure the correspondence between the distribution of the electronic gondola labels and that of the spaces allocated to the respective articles associated with said electronic gondola tags.
    PRESENTATION OF THE INVENTION
    The present invention thus aims to make it possible to determine the distribution of electronic gondola labels of a sales area.
    To this end, a method of locating electronic gondola labels in a sales area is proposed, said sales area having a plurality of electronic gondola labels distributed in said sales area, each of said electronic gondola labels being associated to an article, each of said electronic gondola labels being provided with its own label identifier, said sales area comprising a plurality of radio frequency tags configured to emit radio signals, said method comprising the steps according to which,
    - a portable terminal provided with a radiofrequency locating module receives radio signals emitted by several radiofrequency beacons and determines data originating from the radio signals by means of said radiofrequency locating module;
    - At an acquisition time, the portable terminal acquires the identifier of an electronic gondola label from said electronic gondola label;
    the portable terminal transmits to a central computer server the label identifier and the data from the signals received at the time of acquisition,
    the central computer server determines association data between the electronic gondola tag identified by the label identifier and a position of said electronic gondola label determined from the data originating from the radio signals received at the instant d 'acquisition.
    By providing for a determination of the information allowing the location to be precisely at the time of acquisition, the method makes it possible to effectively determine the location of an electronic gondola tag in a simple and resource-efficient manner. In particular, the fact that it is the portable terminal which both receives radio signals and which acquires the label identifier makes it possible to ensure greater accuracy in locating the electronic gondola label corresponding to the identifying with respect to a process in which it would be the portable terminal which would send the radio signals and the radiofrequency beacons which would receive them.
    The method according to the invention is advantageously but optionally supplemented by the following characteristics, taken alone or in any of their technically possible combinations:
    - the portable terminal also acquires an identifier of an article associated with the electronic gondola label and transmits said article identifier to the central computer server at the same time as the label identifier and the data originating from the radio signals received at the instant of acquisition, and the central computer server determines association data between the electronic gondola tag, the position of the electronic gondola label and the article associated with said electronic gondola label;
    each electronic gondola label is provided with a radiofrequency device and the portable terminal acquires the identifier of the electronic gondola label by establishing radio frequency communication with said electronic gondola label;
    each electronic gondola label is provided with an element for visual representation of the label identifier, and the portable terminal comprises an optical reader suitable for reading said element for visual representation and acquiring the label identifier;
    the radio frequency location module determines the location of the portable terminal from the radio signals emitted by the radio frequency beacons by measuring the propagation time of the respective signals of said radio frequency beacons, and the data originating from the radio frequency signals are position data;
    - the location data are position coordinates;
    the data originating from the radiofrequency signals are measurements of the instant of reception of said signals, and the location of the portable terminal is determined by the central computer server on the basis of said time measurements;
    - The sales area includes a plurality of gondolas carrying the electronic gondola labels, said gondolas defining aisles between them, and radiofrequency beacons are arranged in the extension of the pavements of the sales area;
    - for each of a plurality of pavements, a radiofrequency beacon is arranged on each side of the extension of the aisle;
    - the radiofrequency beacons emit pulses on a frequency band higher than 500 MHz according to the ultra wide band technique.
    The invention also relates to a system for locating electronic gondola labels in a sales area, said sales area having a plurality of electronic gondola labels distributed in said sales area, each of said electronic gondola labels being associated with an article, each of said electronic gondola labels being provided with its own label identifier, said system comprising:

    - a plurality of radio frequency beacons configured to transmit radio signals,

    Preferably, the system is configured to implement the location method according to the invention.
    PRESENTATION OF THE FIGURES
    Other characteristics, objects and advantages of the invention will emerge from the description which follows, which is purely illustrative and not limiting, and which should be read with reference to the appended drawings among which:
    - Figure 1 shows schematically a system for locating electronic gondola labels according to a possible embodiment of the invention;
    - Figure 2 shows a detailed view of the portable terminal of a gondola electronic tag location system according to a possible embodiment of the invention;
    - Figure 3 is a diagram illustrating steps implemented in a method of locating electronic gondola labels according to a possible embodiment of the invention.
    DETAILED DESCRIPTION
    Figures 1 and 2 show an example of a system for locating electronic gondola labels in a sales area. As indicated above, the sales area has a plurality of electronic gondola labels 1 distributed in said sales area, typically at the level of rails 21 running along the shelves 22 of the gondolas 2. The electronic gondola labels 1 are thus visible to consumers of the sales area, and make available to them information relating to articles 10 located in the immediate vicinity of these labels. Typically, the articles 10 are located above or immediately below the electronic gondola label 1 associated with them. Each of the gondola electronic labels 1 is provided with its own label identifier, typically a set of alphanumeric symbols.
    Generally, an electronic gondola label 1 includes a display screen 12 for displaying information relating to an article 10 with which it is associated. Typically, this information includes the price of item 10, and other information usually available in a sales area, such as the price per kilogram for a food item.
    In particular, the electronic gondola tag 1 comprises a radio frequency communication module for receiving data representative of information relating to an article 10 from a central station, a memory for storing said data, and a microcontroller for controlling the posting of information relating to article 10.
    Preferably, the electronic gondola label 1 also includes a radio frequency device for communicating with a portable terminal. The radiofrequency device of the electronic gondola tag 1 can for example comprise an antenna and an electronic chip of NFC (acronym for English Near Field Communication for near field communication) or RFID (acronym for English Radio Frequency Identification) type. for radio frequency identification). An NFC type radiofrequency device operates with a frequency of 13.56 MHz like a HF RFID type radiofrequency device.
    Typically, one can read in each radiofrequency device a unique identifier (UID, acronym for Unique Identifier Data) which is the serial number of the radiofrequency device, and / or information allowing the identification of the label 1. This information allowing the identification of the electronic label of gondola 1 is definitively assigned to the electronic label of gondola 1 during the manufacture of said electronic label of gondola 1, thus constituting an identifier of the electronic label of gondola 1. This identifier is permanently stored in the radio frequency device.
    Due to the one-to-one nature of the relationship between a radio frequency device and an electronic gondola label 1, and the uniqueness of the identifier for both the label and the radio frequency device, a radio frequency device identifier can identify a label electronic gondola, and vice versa, an electronic gondola label identifier 1 can identify a radio frequency device, so that a radio frequency device identifier is also a label identifier.
    Thereafter, the label identifier is called both the serial number and any information allowing the identification of the electronic gondola label 1.
    The system comprises a plurality of radio frequency beacons 4 configured to transmit radio signals. These radiofrequency beacons 4 are distributed in the sales area, preferably at locations allowing good reception of the radio signals for the major part of the sales area. The radiofrequency beacons 4 are preferably placed at a height greater than the height of most of the gondolas 2 of the sales area. The radiofrequency beacons 4 can thus be placed for example on the ceiling of the sales area.
    Furthermore, as a sales area generally comprises a plurality of gondolas 2 carrying the electronic gondola labels 1, which define aisles 5 between them, radiofrequency beacons 4 can be arranged in the extension of pavements 5 of the sales area. Thus, in the example illustrated by FIG. 1, there is illustrated by a dotted line 50 the extension of each aisle 5, passing between the two gondolas 2 defining this aisle 5. The radiofrequency beacons 4 have here been placed against the wall , at the level of the ceiling, and, as indicated by the fact that the dotted lines 50 pass through the radiofrequency beacons 4, in the extension of the aisles 5.
    Preferably, for the majority of aisles 5 of the sales area, a radio frequency beacon 4 is arranged at each end of the extension of these aisles 5, so that for each aisle 5, the radio signals emitted by at least one of the two beacons 4 opposite radio frequencies can reach any point on this aisle 5.
    The radiofrequency beacons 4 emit pulses on a frequency band greater than 500 MHz according to the ultra wideband technique, better known by the English name of Ultra wideband, which is a radio modulation technique which is based on the transmission of pulses of very short duration, often less than a nanosecond. Thus, the bandwidth reaches very high values.
    Such a system also includes a central computer server 6. The central computer server 6 is generally remote, since it is not physically present in the sales area. The central computer server 6 is a hardware computing device which comprises at least one processor, hardware communication interfaces, and memories in which databases are stored.
    Among these databases are association data between electronic gondola labels 1 and respective positions of said electronic gondola labels 1. This association data can for example take the form of a link between an identifier of label of an electronic label of gondola 1 and data representative of the position of said electronic label of gondola 1, for example the coordinates thereof.
    The system also includes a portable terminal 3. The portable terminal 3 is adapted to acquire an identifier of an electronic gondola label 1 from an electronic gondola label 1. Preferably, the portable terminal 3 can establish communication without wire, typically by radio frequency, with the electronic gondola label 1 to acquire the label identifier of said electronic gondola label 1. The portable terminal 3 can also establish communication by infrared or visible light with the electronic label gondola 1. The portable terminal 3 can also acquire the identifier of an electronic gondola label by other means, for example by reading a visual representation of the label identifier placed on the electronic label gondola 1 or displayed by the electronic gondola label, such as a barcode 13.
    The portable terminal 3 is provided with a radiofrequency location module, configured to exploit the radio signals coming from the radiofrequency beacons 4 so that the portable terminal 3 can determine data originating from the radio signals by means of said radiofrequency location module. The radiofrequency localization module can in particular have one or more antennas dedicated to the reception of the radio signals emitted by the radiofrequency beacons 4.
    Each radiofrequency beacon 4 emits a radio signal making it possible to identify it, typically encoding an identifier. This identifier can for example be coded in a pulse train, or else correspond to a particularity of the radio signal. The radio signals carry time information, and in particular information on their transmission times by their respective radiofrequency beacons 4. Preferably, this time information is found in the instant of transmission of the radio signals. For example, when the radio signals present pulses or pulse trains, a radiofrequency beacon 4 transmits a pulse or a pulse train in a temporally isolated manner at an instant of resignation. The time information then corresponds to the instant of emission of the pulse itself, or to the start or the end of the train of pulses. This time information could also take an explicit form, and be encoded in radio signals. More generally, the radio signals are considered to include time information when these radio signals make it possible to determine a time, or at least a time difference, when one or more radiofrequency beacons 4 are used.
    The transmissions of these pulses or these pulse trains by different radiofrequency beacons 4 are synchronized, so that these radiofrequency beacons 4 simultaneously transmit a pulse or a pulse train making it possible to identify each radiofrequency beacon 4 emitting.
    The central computer server 6 is configured to be able to communicate, typically via a wireless network 60, with the portable terminal 3, in order at least to receive data sent by said portable terminal 3. Communication between the portable terminal 3 and the computer server central 6 can be established by any at least partially wireless communication network, in particular via a DECT, WIFI or 3G type wireless network. Thus, communication can be established via the internet network to which the central computer server 6 is connected.
    With reference to FIG. 3, the method for locating electronic gondola labels in a sales area comprises a first step (step S1) during which radio frequency beacons 4 transmit radio signals in the sales area. These radio signals are therefore propagated in the sales area, and in particular in the aisles 5 defined between the gondolas 2, where people carrying portable terminals 3 are likely to be located. This first stage extends for a certain duration, c that is to say that the radiofrequency beacons 4 transmit radio signals repeatedly, typically at very close intervals or even less than a second, for a period of time which is greater than one minute. The emission of signals can for example be controlled at the start of the determination of the distribution of a plurality of electronic gondola tags, and then stopped (via a command of the radio frequency beacons 4).
    A portable terminal 3 present in the sales area then receives (step S2) radio signals emitted by several of said radiofrequency beacons. Depending on the location of the portable terminal 3 in the sales area, the radio signals transmitted by a radio frequency beacon 4 take more or less time to reach the portable terminal 3. Thus, radio signals transmitted simultaneously by different radio frequency beacons 4 are received by the portable terminal 3 at different times of reception, although sharing the same time of resignation. However, the differences between the instants of reception between radio signals emitted at the same time of transmission by different radio frequency beacons 4 are small (at least two times lower) compared to the intervals between two times of transmission. Thus, the radio signals received by the portable terminal during a limited time interval can be considered to have been transmitted at the same time of transmission.
    To acquire the location of an electronic gondola label 1 (step S3), an operator 7 provided with a portable terminal 3 approaches said portable terminal 3 of the electronic gondola label 1, so as to be able to acquire the identifier d 'label of the electronic gondola label 1. Typically, this acquisition is done by means of a wireless communication by which the electronic label of gondola 1 transmits its label identifier to the portable terminal.
    For example, when the electronic label of gondola 1 is provided with a radio frequency device, it is a question of ensuring that the radio frequency device of the electronic label of gondola 1 is within range of electromagnetic waves emitted by the terminal. portable 3. The radiofrequency device is then activated by the energy of the electromagnetic waves emitted by the portable terminal 3 in order to establish radiofrequency communication with the radiofrequency device of the electronic gondola tag 1. The radiofrequency device of the tag electronics of gondola 1 then in turn transmits electromagnetic waves carrying data on the label identifier to the portable terminal 3. The electronic label of gondola 1 thus transmits its label identifier to the portable terminal 3 which therefore acquires it .
    Other means of acquiring the label identifier can be implemented. One can for example provide a wireless communication not using radio waves, but light waves, visible or invisible such as infrared waves. When the electronic gondola label 1 is provided with an element for visual representation of the label identifier, it is a matter of being visible by an optical reader of the portable terminal 3, and the portable terminal 3 reads then this label identifier.
    The portable terminal 3 can also acquire an article reference of an article 10 associated with the electronic gondola label 1. For example, the portable terminal 3 can read a visual reference of the article 10, such as a barcode . The portable terminal 3 can also read a radio frequency chip attached to article 10 if this is provided. The operator can also enter this article reference on the portable terminal 3 by means of inputting information present thereon, such as a keyboard or a touch screen.
    As explained above, it can also be provided that the portable terminal 3 does not directly recover a tag serial number from the electronic gondola label 1, as in the cases presented above but that the portable terminal 3 recovers from the electronic label of gondola 1, in the above ways, label information allowing the identification of the electronic label of gondola 1. This information allowing the identification of the electronic label of gondola 1 is definitively assigned to the label during the manufacture of said label, thus constituting an identifier of the label. This information can for example be composed of a prefix followed by a reference number of the label forming the label identifier, such as www.SESimagotag.com/123456789, the suffix www.SES-imagotag.com allowing recognize the information as being capable of being communicated by the portable terminal 3 to a remote server determined by the suffix to recover a serial number from the electronic gondola label 1. In any case, the moment when the portable terminal 3 acquires, directly or indirectly, the label identifier from an electronic gondola label 1, constitutes for the portable terminal 3 an acquisition instant.
    The portable terminal 3 acquires the radio signals received at this acquisition time, using the radio frequency location module, and determines (step S4) data from the radio signals by means of said radio frequency location module. The portable terminal 3 can determine data from the radio signals permanently as long as the reception of the radio signals lasts. Only the data from the radio signals received at the time of acquisition are analyzed or transmitted.
    Preferably, while the portable terminal 3 receives and receives repeatedly over a period of time radio signals from radio frequency beacons 4, the portable terminal 3 does not process the radio signals received except those received at the time of acquisition, which allows a considerable saving of resources for the portable terminal 3. The exploitation of this data from the radio signals makes it possible to locate the portable terminal 3.
    The portable terminal 3 transmits (step S5) to the central computer server 6 the label identifier and the data from the signals received at the time of acquisition. If the article reference of an article 10 associated with the electronic gondola label 1 has been acquired by the portable terminal 3, said article reference can also be transmitted to the central computer server 6 at the same time as the label identifier and data from radio signals received at the time of acquisition. The label identifier, the data from the signals received at the time of acquisition, and possibly the article reference, are therefore associated by their simultaneous, or at least successive, transmission.
    The central computer server 6 determines (step S6) association data between the electronic gondola label 1 identified by the label identifier and a position of said electronic gondola label 1 determined from the data from the radio signals received at the time of acquisition.
    The position of the electronic gondola label 1 is determined from the position of the portable terminal 3 at the time of acquisition. As the portable terminal 3 is close to the electronic gondola label 1 at this acquisition time, the position of the electronic gondola label 1 is assimilated to the position of the portable terminal 3.
    The radiofrequency locating module of the portable terminal 3 can itself process the radio signals emitted by the radiofrequency beacons 4 in order to determine its position, and therefore that of the electronic gondola tag 1. The radiofrequency locating module can determine the position of the portable terminal 3 from the radio signals emitted by the radio frequency beacons 4 by measuring the propagation time of the respective signals of said radio frequency beacons 4. For example, the portable terminal 3 can evaluate the distance between the portable terminal 3 and each radio frequency beacon 4 by analyzing the time information of the radio signals, by combining them with the times of reception of the radio signals, since each radio signal identifies the radiofrequency beacon which transmitted it. In particular, with simultaneous transmissions of radio signals by different beacons, the different instants of reception by the portable terminal 3 make it possible to determine the distances from each radiofrequency beacon. By using several radiofrequency beacons 4, it is therefore possible to determine the location of the portable terminal 3, and therefore of the electronic gondola label 1, by trilateration or triangulation for example.
    The data originating from the radiofrequency signals are then position data, that is to say data which translate a position. This position data can for example be position coordinates. This position data is transmitted to the central computer server 6 as data from the signals received at the time of acquisition.
    The data originating from the radiofrequency signals can be measurements of instants of reception of said signals, and the location of the portable terminal 3 is then determined by the central computer server from said time measurements.
    As explained above for the portable terminal 3, the central computer server 6 can determine the position of the electronic gondola label 1 from data from the radio signals received at the time of acquisition, by comparing between data from radio signals from different radio frequency beacons 4.
    The association data indicates that the electronic gondola label 1 in question is at a precise position in the sales area, which can for example be encoded by means of coordinates in a marker, or preferably still, corresponds to a location. predetermined in the sales area. Indeed, the electronic labels of gondola 1 are not found anywhere in the sales area, but precisely on gondolas 2 (hence their name) or similar elements. It is therefore possible to have a set of locations defined in the sales area, which can be assigned as a position to the electronic gondola labels 1.
    Therefore, their location in the sales area can be specified by assigning them the closest location. This can for example be the combination of a gondola reference 2, a shelf number 22, and a distance along the rail 21. The reference of a gondola 2 can also correspond to location information, and by example consist of an aisle number 5 and order in this aisle 5.
    Whatever the solution chosen for managing the knowledge of the position of an electronic gondola label 1, the association data can take different forms allowing their exploitation. In particular, provision can thus be made for knowing the location of each article 10, thanks to the electronic gondola label 1 which is associated with it.
    If the article reference has not been acquired by the portable terminal 3, the label identifier can be used to find in an dedicated database the article reference of the article associated with the electronic gondola label 1 identified by the label identifier. Information is also obtained on the position of each item 10 in the sales area.
    All of the association data therefore forms a planogram, as indicated above. Thanks to this process, one can thus establish the planogram, modify it, or update it. In particular, any movement of electronic gondola label 1 in the sales area can immediately be reflected on the planogram, which makes it possible to adapt it in real time. The invention thus makes it possible to make the planogram a faithful representation of the sales area.
