Description

DISPLAY CASE FOR PRODUCTS WITH RFID TAGS DESCRIPTION:

The present invention generally relates to the product display cases, each provided with a radio wave identification system, called RFID tags, such as food products.

The showcase (1) which has metal walls except the face constituting the door, glazed and translucent (2) to see the products available for sale (3), is equipped with an electronic processing system and computer (4) which comprises means of communication, called RFID reader which is composed of at least one antenna (5) located inside the enclosure and able to communicate by radio waves with the RFID tags (6) of the products presented in the enclosure (3). This or these RFID antennas are placed inside the showcase to detect the products it contains. The showcase has a closure system (7). The electronic and computer processing system also comprises a system for producing an inventory of the products present in the enclosure and an inventory of the products taken out, composed of a transparent anti-wave film (8), filtering the ultra electromagnetic waves. high frequency, applied to the glazed part of the showcase and an algorithm that then makes it possible to filter the products out of those left in the showcase by comparison between the detection data of the labels of the previous inventories and the inventory detection data. after sales. This mechanism works even if an output product is still detected by the RFID reader.

The showcase allows the distribution and sale of the products it contains. It allows you to know at any time the exact inventory of the products it contains and to know which user took out which product.

We know the state of the art of showcases such as that described above. There are two examples.

A French patent FR 2964217, filed by the Société de Logistique et de Distribution Alimentaire, published on March 2, 2012 at BOPI 2012-09 and a US patent WO2015076949 A1, filed by Pantry Retail Inc., published in the WIPO bulletin May 28, 2015. The patents allow the detection of the released products, but only on the basis of the absence of reception of the data of the labels, so if a label is no longer detected, it is that the product is out. As regards the French patent, at the level of the filtering carried out by transparent metallic micro-mesh, 32 db of filtering, it is described that "thanks to such a showcase according to the invention whose or each door is equipped with a blocking screen the communication between the RFID reader and the RFID tags of the products left the enclosure of the window, it can be sure that once the desired product or products removed from the enclosure of the window by the user and once the closed door, the RFID tags of products exiting the enclosure will no longer be detected by the RFID reader ". Regarding the US patent, if mechanisms make it possible to locate the products inside the showcase, thanks in particular to the transmit power of the antennas or the power of reception of the signal of the labels, it is nowhere made mention of the use of this technique to know if a product has been released.

In this context, it has been found that, until now, it has been impossible to efficiently filter out the products that have been released, that is to say, to distinguish the products that have emerged from those that have remained and thus to accurately compare the initial and final inventories. Indeed, a product that has been released and placed far from the window will not in any case be detected by the RFID reader and will be detected as output, the difficulty remaining for the products that remain near the antennas and can therefore be detected despite the filter.

In the present invention, the conjunction of use of a metal film and an algorithmic treatment makes it possible to effectively filter the labels of the products released.

Indeed, to improve the reliability of the detection and to detect which products have been released with a very small source of errors (less than 1% of the flux), two mechanisms are put in place: 1. A transparent anti-wave film ( 8), filtering ultra-high frequency electromagnetic waves, is applied to the glass part of the showcase. 2. An algorithmic filter executed by the computation unit of the computer and computer processing system (4) of the computer integrated in the showcase, then makes it possible to filter the products left those left in the showcase by comparison between the data of detection of the labels of previous inventories and the detection data of the after-sales inventory. This mechanism works even if a product is still detected. The invention can be extended to any means limiting the power of the signal of the supply and / or communication waves of the RFID tags of the products coming out of the showcase, whether it is the door (2) whose window has has undergone a treatment that gives it ultra-high frequency electromagnetic wave filter properties, a filter regardless of its composition, or a system for jamming power supply waves and / or RFID tag communication.

Before starting the sale, the products are put in the showcase by the operator.

A sale consists of an initial inventory, then the withdrawal of products, and a final inventory. During the initial inventory, it is checked whether the products present during the last inventory are still detected. If this is not the case, they are removed from the inventory. Once the door closed by the customer, the final inventory is launched. If a product from the initial inventory is no longer detected, it is removed from inventory and added to the cart. For products still detected by the RFID reader, the algorithm processes the signal characteristic variations (RSSI, Doppler frequency variation, phase angle, antenna read number, and any other signal reception data) and deduce if the product was taken out of the showcase or not. The mechanism works even if an output product is still detected by the RFID reader. If a product has been removed from the showcase (1), it is added to the basket.

The present invention makes it possible to know automatically, very quickly, almost instantaneously and with optimal precision the flow of products between the inside and the outside of the showcase.
