Definitions
- the present invention relates generally to the management of electronic gondola tags distributed along a rail of a gondola of a sales area. More precisely, it concerns the determination of the distribution of these electronic gondola labels, each of said gondola electronic tags being provided with an identifier specific to said gondola electronic tag.
- the electronic gondola tags are arranged along rails, said rails being themselves arranged along the outer ends of the shelves of the gondola.
- the electronic gondola labels are thus visible to the consumers of the sales area, and communicate to them information relating to articles located in the immediate vicinity of these electronic gondola labels.

- serial number is then referred to as both the serial number and any information enabling the identification of the electronic gondola label 1.
- the system includes a plurality of radio frequency tags 4 configured to transmit radio signals.
- These radiofrequency beacons 4 are distributed in the sales area, preferably at locations allowing good reception of radio signals for most of the sales area.
- the radiofrequency beacons 4 are preferably arranged at a height greater than the height of most of the gondolas 2 of the sales area.
- the radiofrequency tags 4 can thus be arranged for example on the ceiling of the sales area.

- 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 tag identifier placed on the electronic gondola label 1 or displayed by the electronic gondola label, such as a bar code 13.
- the portable terminal 3 is provided with a radiofrequency localization module, configured to exploit the radio signals coming from the radiofrequency beacons 4 so that the portable terminal 3 can determine data derived from the radio signals by means of said radio frequency localization module.
- the radiofrequency localization module may 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 transmits a radio signal making it possible to identify it, typically encoding an identifier.
- This identifier can for example be encoded in a pulse train, or correspond to a particularity of the radio signal.
- the radio signals carry a time information, and in particular information on their transmission times by their respective radio frequency beacons 4.
- this time information is in the instant of transmission of the radio signals.
- a radiofrequency beacon 4 transmits a pulse or a pulse train at a time of emission in a time-isolated manner.
- the time information corresponds to the time of emission of the pulse itself, or at the beginning or at the end of the pulse train.
- This time information could also take an explicit form, and be encoded into the radio signals.
- the radio signals are considered to have 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 emissions of these pulses or pulse trains by different radio frequency beacons 4 are synchronized, so that these radiofrequency beacons 4 simultaneously emit a pulse or a pulse train making it possible to identify each radiofrequency beacon 4 emitting.

- the communication can be established via the internet network which is connected to the central computer server 6.
- the method of locating electronic gondola labels in a sales area comprises a first step (step S1) during which radio frequency tags 4 emit 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 there are likely to be people carrying portable terminals 3.
- This first step extends for a certain period of time. that is, the radio frequency beacons 4 transmit radio signals repeatedly, typically at very close or even less than one second intervals, for a period of time which is greater than one minute.
- the transmission of signals can for example be controlled at the beginning of the determination of the distribution of a plurality of electronic gondola labels, and then stopped (via a control of radio frequency tags 4).
- a portable terminal 3 present in the sales area receives (step S2) then radio signals emitted by several of said radio frequency beacons.
- the radio signals transmitted by a radiofrequency beacon 4 take more or less time to reach the portable terminal 3.
- radio signals emitted simultaneously by different Radio frequency tags 4 are received by the portable terminal 3 at different reception times, although sharing the same transmission time.
- the differences between the reception times between radio signals transmitted at the same time of transmission by different radio frequency beacons 4 are weak (at least twice as low) compared to the intervals between two times of emission.
- the radio signals received by the portable terminal during a restricted time interval can be considered as having been transmitted at the same time of transmission.
- an operator 7 equipped with a portable terminal 3 approaches said portable terminal 3 of the electronic tag of gondola 1, so as to be able to acquire the identifier of Electronic Gondola Tag Label 1.
- this acquisition is done through a wireless communication by which the electronic tag gondola 1 transmits its tag identifier to the portable terminal.
- the electronic tag gondola 1 when the electronic tag gondola 1 is provided with a radio frequency device, it is to ensure that the radiofrequency device of the electronic tag gondola 1 is within range of electromagnetic waves emitted by the terminal 3. The radiofrequency device is then activated by the energy of the electromagnetic waves emitted by the portable terminal 3 in order to establish a radio frequency communication with the radiofrequency device of the electronic gondola label 1. The radiofrequency device of the electronic gondola tag 1 then transmits electromagnetic waves carrying data on the tag identifier to the portable terminal 3. The gondola electronic tag 1 thus transmits its tag identifier to the terminal portable 3 who acquires it so.
- tag identifier can be implemented. For example, it is possible to provide a wireless communication that does not use radiofrequency waves, but light waves, visible or invisible, such as infrared waves.
- a wireless communication that does not use radiofrequency waves, but light waves, visible or invisible, such as infrared waves.
- the electronic tag of gondola 1 is provided with a visual representation element of the tag identifier, it is that it is visible by an optical reader of the portable terminal 3, and the portable terminal 3 reads then this tag identifier.
- the portable terminal 3 can also acquire an article reference of an article 10 associated with the electronic gondola label 1.
- the portable terminal 3 can read a visual reference of article 10, such as a barcode.
- the portable terminal 3 can also read a radiofrequency chip attached to the article 10 if it has one.
- the operator can also enter this item reference on the portable terminal 3 through input means of information present on it, such as a keyboard or a touch screen.
- the portable terminal 3 does not directly retrieve a label serial number from the label.
- electronic gondola 1 as for the cases presented above but that the portable terminal 3 recovers from the electronic label gondola 1, in the above ways, a label information for the identification of the label electronic gondola 1.
- This information enabling the identification of the electronic label of gondola 1 is definitively attributed to the label during the manufacture of said label, thus constituting an identifier of the label.
- This information may for example be composed of a prefix followed by a reference number of the label forming the label identifier, such as www.SES-imagotag.com/123456789, the suffix "www.SES-imagotag .com "for recognizing the information as being capable of being communicated by the portable terminal 3 to a remote server determined by the suffix to retrieve a serial number of the electronic tag gondola 1.
- the moment when the portable terminal 3 acquires, directly or indirectly, the tag identifier from an electronic gondola tag 1 constitutes for the portable terminal 3 a moment of acquisition.
- the portable terminal 3 acquires the radio signals received at this moment of acquisition, using the radiofrequency localization module, and determines (step S4) data from the radio signals by means of said radiofrequency localization module.
- the portable terminal 3 can determine data from the radio signals permanently as long as the reception of the radio signals lasts. Only data from radio signals received at the time of acquisition are analyzed or transmitted.
- the portable terminal 3 While the portable terminal 3 repeatedly picks up and receives radio signals from radiofrequency beacons 4 over a period of time, the portable terminal 3 does not process the received radio signals except those received at the instant of time. acquisition, which allows a considerable saving of resources for the portable terminal 3. The exploitation of these data from the radio signals can locate the portable terminal 3.
- the portable terminal 3 transmits (step S5) to the central computer server 6 the tag identifier and the data from the signals received at the time of acquisition. If the reference article of an article 10 associated with the electronic tag of gondola 1 has been acquired by the portable terminal 3, said article reference can also be transmitted to the central computer server 6 together with the tag identifier and the data from the radio signals received at the time of acquisition.
- the tag identifier, the data from the signals received at the time of acquisition, and possibly the article reference, are therefore associated by their simultaneous transmission, or at least successive.
- the central computer server 6 determines (step S6) association data between the gondola electronic tag 1 identified by the tag identifier and a position of said gondola electronic tag 1 determined from the data from the radio signals. received at the time of acquisition.
- the position of the electronic tag of gondola 1 is determined from the position of the portable terminal 3 at the moment of acquisition. Since the portable terminal 3 is close to the electronic gondola label 1 at this moment of acquisition, the position of the electronic gondola label 1 is assimilated to the position of the portable terminal 3.
- the radiofrequency localization 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 label 1.
- the radiofrequency localization module can determine the position of the portable terminal 3 from the radio signals emitted by the radiofrequency 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 radiofrequency beacon 4 by analyzing the time information of the radio signals, combining them with the times of reception of the radio signals, since each radio signal identifies the radiofrequency beacon which has emitted it.
- the different times of reception by the portable terminal 3 make it possible to determine the distances with respect to each radio frequency beacon.
- the data resulting from the radiofrequency signals are then position data, that is to say data that translate a position. These position data may for example be position coordinates.
- This position data is transmitted to the central computer server 6 as data from the signals received at the acquisition time.
- the data derived from the radio frequency signals may be measurements of times 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.
- the central computer server 6 can determine the position of the electronic tag gondola 1 from the data from the radio signals received at the time of acquisition, comparing between they are data coming from radio signals coming from different radio frequency beacons 4.
- Other modes for determining the location of the portable terminal 3 may be envisaged, as an alternative to detection by radiofrequency beacons.
- the portable terminal 3 may be provided with a positioning module capable of receiving a visible light signal on a frequency between 400 and 800 THz.
- the radiofrequency beacons can be replaced by luminaires with light-emitting diodes or LED luminaires, arranged at known positions in the sales area.
- a database with which the central server 6 can communicate contains location information of each of the LED luminaires in the sales area.
- the emission of light signals can for example be controlled at the beginning of the determination of the location of a plurality of electronic gondola labels, and then stopped.
- the portable terminal 3 receives a light signal or a series of light signals (visible light communication code (s), or VLC for Visible Light Communication) emitted by one or more LED luminaires, VLC codes for uniquely identifying luminaires.
- the positioning module of the portable terminal 3 is configured to recognize the VLC code specific to each LED luminaire, and to communicate with the central server 6 to remove the location data of the LED luminaires, so as to determine in step S4 data location of the portable terminal 3.
- the wireless communication modalities between the portable terminal 3 and the electronic gondola labels 1, in particular the step S3 of acquisition by the portable terminal 3 of a tag ID 3 in the vicinity, are unchanged with respect to the method of FIG. 3. Furthermore, the step S5 of communication between the portable terminal 3 and the central server 6 is also preserved.
- the association data determined in step S6 for an electronic gondola tag 1 indicates that the gondola electronic tag 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 more preferably, corresponds to a predetermined location in the sales area. Indeed, the electronic labels of gondola 1 are not found anywhere in the sales area, but precisely on the gondolas 2 (hence their name) or similar elements. A set of locations defined in the sales area can thus be available, which can be assigned as a position to the electronic gondola labels 1.
- gondola reference 2 may 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 may also correspond to location information, and for example consist of an aisle number 5 and order in this aisle 5.
- the association data can take various forms allowing their exploitation. In particular, it can be expected to know the location of each article 10, thanks to the electronic tag gondola 1 associated with it.
- the tag identifier can be used to find in a dedicated database the article reference of the article associated with the gondola electronic tag 1 identified. by the tag ID. We then also obtain information on the position of each article 10 in the sales area.
- the set of association data thus forms a planogram, as indicated above. Thanks to this process, it is possible to establish the planogram, to modify it, or to update it. In particular, any movement of electronic label 1 of the gondola in the sales area can immediately be reflected on the planogram, which allows to adapt it in real time.
- the invention thus makes it possible to make the planogram a faithful representation of the sales area.
