Description

Technical Field

[0001] This utility model relates to the field of electronic price tag technology, and in particular to an electronic tag device and a system with positioning function. Background Technology

[0002] Currently, in supermarkets and other retail operations, paper price tags are generally being replaced with electronic price tags to display product information in order to reduce labor costs. To achieve intelligent electronic price tags that accurately identify the corresponding products and display product information, NFC tag systems with positioning capabilities are commonly used. These systems use an NFC reader coil to read the encoded information from the NFC tag and upload it to a data center. The data center then retrieves pre-stored tag location information and the corresponding product information based on this encoded information. This information is then sent to the electronic price tag, which displays the correct product information. The electronic price tag can also upload this product information to a backend system, allowing the backend to generate a product display image based on the different product information and their corresponding location.

[0003] However, in actual use, the above system may encounter problems such as positioning blind spots. That is, during the actual installation of electronic shelf labels, due to various limitations, it is impossible to guarantee that the installers will install the electronic shelf labels and the NFC tags on the shelves in completely corresponding positions. After the electronic shelf labels are installed on the shelves, there may be a situation where the NFC reading coil in the electronic shelf label does not match the position of the NFC tag preset on the shelf, resulting in the NFC reading coil in the electronic shelf label not being able to read the information of the NFC tag. This will cause the electronic shelf label to fail to display product information or to display product information incorrectly.

[0004] Therefore, this utility model proposes an electronic tag device and a system with positioning function to overcome the defects of the prior art. Utility Model Content

[0005] The purpose of this utility model is to provide an electronic tag device and a system with positioning function, which integrates multiple electronic tags into a whole and sets them on a shelf. By optimizing the arrangement of multiple electronic tags, the electronic price tag at any position on the shelf can read the coded information in the corresponding electronic tag, thereby achieving accurate positioning of the electronic price tag and ensuring accurate display of product information at the corresponding position.

[0006] The objective of this utility model can be achieved by the following solutions:

[0007] This utility model provides an electronic tag device for reading and identifying preset electronic price tags. The electronic tag device includes:

[0008] Base strip;

[0009] Multiple electronic tags are disposed on the base strip and arranged along the length of the base strip, such that when the electronic price tag and the electronic tag device are assembled, the projection of the electronic price tag on the base strip overlaps with the projection of at least one electronic tag, which is half or more than half, on the base strip.

[0010] In a preferred embodiment of the present invention, there is a first gap between two adjacent electronic tags, and the width of the first gap is smaller than the projection width of the electronic price tag on the base strip;

[0011] When the projection of the electronic price tag on the base strip overlaps with the projections of two adjacent electronic tags on the base strip, at least one of the two adjacent electronic tags is read and identified by the electronic price tag.

[0013] In a preferred embodiment of the present invention, in the width direction of the base strip, both the first electronic tag and the second electronic tag have a second gap between themselves and the edge of the base strip.

[0014] In a preferred embodiment of the present invention, the electronic tag device further includes a frequency modulation layer for reducing the resonant point of the electronic tag, the frequency modulation layer being disposed on the base strip, and the electronic tag being located between the base strip and the frequency modulation layer;

[0015] When the electronic tag device is installed on the shelf, the frequency modulation layer is located on the side closer to the shelf.

[0016] In a preferred embodiment of this utility model, a protective layer is provided on the base strip, and the protective layer covers the outside of the frequency modulation layer;

[0022] An electronic price tag is mounted on the guide rail;

[0023] In the aforementioned electronic tag device, the electronic tag device is disposed within the channel, and the projection of the electronic price tag on the base strip of the electronic tag device overlaps with the projection of half or more of at least one electronic tag in the electronic tag device on the base strip.

[0024] In a preferred embodiment of the present invention, the electronic tag device extends along the length of the channel, and the electronic tag device is sandwiched between the bottom wall of the channel and the electronic price tag.

[0025] As described above, the features and advantages of the electronic tag device and the system with positioning function of this utility model are as follows: multiple electronic tags are arranged along the length of the base strip, so that the multiple electronic tags form a whole on the base strip. The electronic price tag is set within the range of the base strip, and the electronic price tag is set close to the electronic tag. No matter how the position of the electronic price tag is set, it is guaranteed that the projection of the electronic price tag on the base strip overlaps with the projection of at least half or more of the electronic tag on the base strip.

[0045] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate this utility model and are not intended to limit the scope of this utility model. After reading this utility model, any modifications of this utility model in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.

[0046] It should be noted that when an element is referred to as being "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0048] In practical applications (such as supermarket operations), in order to reduce labor costs, paper price tags are now generally being replaced by electronic price tags to display product information. To achieve intelligent electronic shelf labels and accurately identify and display product information corresponding to them, an NFC tag system can be used for positioning. This involves using an NFC reader coil embedded in the electronic shelf label to read the encoded information from the NFC tag. This encoded information is then uploaded to a data center. The data center retrieves pre-stored shelf label location information and the corresponding product information based on this encoded information. This information is then sent back to the electronic shelf label, allowing it to display the correct product information. However, this system encounters a blind spot problem, as mentioned in the background section, where the NFC reader coil in the electronic shelf label may fail to read the encoded information from the NFC tag. To prevent this, this invention places multiple NFC tags 2 on a base strip 1, ensuring that the multiple NFC tags 2 on the base strip 1 can always match the NFC reader coil in the electronic shelf label 10. Placing the electronic shelf label 10 at any location within the base strip 1 ensures that at least one NFC tag's encoded information is read, thereby achieving high-precision positioning of the electronic shelf label 10 on the shelf and guaranteeing accurate display of product information.

[0049] The specific structure of the electronic tag device of this utility model is described below:

[0050] Implementation Method 1

[0051] like Figures 1 to 4As shown, this utility model provides an electronic tag device 30, which is used to be read and identified by a preset electronic price tag 10. The electronic tag device 30 includes a base strip 1 and a plurality of electronic tags 2. The plurality of electronic tags 2 are disposed on the base strip 1 and are arranged along the length direction of the base strip 1, such that when the electronic price tag 2 is assembled with the electronic tag device 30, the projection of the electronic price tag 10 on the base strip 1 overlaps with the projection of at least one electronic tag 2, or more than half of the portion, on the base strip 1.

[0052] The electronic tag 2 in this invention is preferably an NFC tag.

[0053] This invention arranges multiple electronic tags 2 along the length of a base strip 1, forming a single unit on the base strip 1. An electronic price tag 10 is positioned within the base strip 1, close to the electronic tags 2. This ensures that regardless of its location within the base strip 10, the projection of the electronic price tag 10 onto the base strip 1 overlaps with the projection of at least half or more of the electronic tag 2 onto the base strip 1. This ensures that the NFC reading coil in the electronic price tag 10 can always accurately read the encoded information from the corresponding electronic tag 2, achieving accurate positioning of the electronic price tag 10 and guaranteeing accurate display of product information at the corresponding location.

[0054] In this invention, when the electronic price tag 10 and the electronic tag device 30 are actually assembled, and only one electronic price tag 10 is set at a position opposite to the base strip 1, the projection of the electronic price tag 10 on the base strip 1 can overlap with the projection of at least half or more of the electronic tag 2 on the base strip 1 at any position within the range opposite to the base strip 1. This ensures that the NFC reading coil in the electronic price tag 10 can accurately read the encoded information in the electronic tag 2 at the corresponding position. When multiple electronic price tags 10 are set at a position opposite to the base strip 1, the projection of each electronic price tag 10 on the base strip 1 can overlap with the projection of at least half or more of the electronic tag 2 on the base strip 1. This ensures that the NFC reading coil in each electronic price tag 10 can accurately read the encoded information in the electronic tag 2 at the corresponding position.

[0055] In one optional embodiment of this utility model, such as Figure 1As shown, there is a first gap 3 between two adjacent electronic tags 2, and the width of the first gap 3 is smaller than the projection width of the electronic price tag 10 on the base strip 1. When the projection of the electronic price tag 10 on the base strip 1 and the projection of the two adjacent electronic tags 2 on the base strip 1 have overlapping areas, it is guaranteed that the encoded information in at least one of the two adjacent electronic tags 2 can be read by the NFC reading coil of the electronic price tag 10. This arrangement involves the non-overlapping placement of adjacent electronic tags 2, maintaining a certain distance (i.e., the first gap 3) between them. This prevents magnetic coupling between adjacent electronic tags 2. Due to the presence of the first gap 3, this arrangement is generally suitable for an electronic price tag 10 with two NFC reading coils. When one NFC reading coil in the electronic price tag 10 cannot read the encoded information in the electronic tag 2 or the reading signal is weak, the other NFC reading coil in the electronic price tag 10 can ensure accurate reading of the encoded information in the electronic tag 2. Of course, this arrangement is also suitable for cases where the electronic price tag 10 has a large dimension in the length direction of the base strip 1, ensuring that the dimension of the electronic price tag 10 in the length direction of the base strip 1 is greater than the sum of the length of one electronic tag 2 and the dimension of the first gap 3, thereby ensuring that the NFC reading coil in the electronic price tag 10 can accurately read the encoded information in the electronic tag 2.

[0056] In another optional embodiment of this utility model, such as Figure 2 As shown, the electronic tag 2 includes multiple first electronic tags 201 and multiple second electronic tags 202. The multiple first electronic tags 201 are arranged at intervals along the length direction of the base strip 1, and there is a first gap 3 between two adjacent first electronic tags 201. At least one second electronic tag 202 is disposed between two adjacent first electronic tags 201, and there is an overlapping area between the second electronic tag 202 and its two adjacent first electronic tags 201. The arrangement of the second electronic tag 202 can completely cover the first gap 3 between two adjacent first electronic tags 201, avoiding the situation where the electronic price tag 10 cannot read the encoded information in the electronic tag 2 due to the existence of the first gap 3. When the size of the electronic price tag 10 is small, in order to avoid the existence of the first gap 3 causing the electronic price tag 10 to be unable to read the encoded information in the electronic tag 2 (e.g., the size of the first gap 3 is larger than the size of the electronic price tag 10 in the length direction of the base strip 1, and the electronic price tag 10 is exactly set at the position opposite to the first gap 3), a second electronic tag 202 can be added between two adjacent first electronic tags 201 and the second electronic tag 202 and the first electronic tag 201 have an overlapping area. This method can enhance the magnetic field coupling effect.

[0057] In this embodiment, as Figure 2As shown, in the width direction of the base strip 1, a second gap 9 needs to be left between the first electronic tag 201 and the second electronic tag 202 and the edge of the base strip 1, so that the magnetic field lines generated by the first electronic tag 201 and the second electronic tag 202 can pass through the second gap 9 to form a closed curve.

[0058] It is understandable that when only the first electronic tag 201 is set and the second electronic tag 202 is not set, a second gap 9 is also required between the edge of the first electronic tag 201 and the base strip 1 in the width direction of the base strip 1, so that the magnetic field lines generated by the first electronic tag 201 can pass through the second gap 9 to form a closed curve.

[0059] In this invention, the electronic tag 2 can be rectangular, rectangular-like, or elliptical. Rectangular or rectangular structures offer better space utilization, while elliptical structures cause less interference between adjacent electronic tags 2. The shape of the electronic tag 2 can be set according to actual conditions and signal transmission requirements; therefore, the specific shape of the electronic tag 2 is not limited herein.

[0060] In one optional embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the electronic tag device 30 also includes a frequency modulation layer 5 for reducing the resonant point of the electronic tag 2. The frequency modulation layer 5 is disposed on the base strip 1, and the electronic tag 2 is located between the base strip 1 and the frequency modulation layer 5. When the electronic tag device 30 is installed on a shelf, the frequency modulation layer 5 is located on the side closer to the shelf. In the actual installation state, the electronic tag device 30 and the electronic price tag 10 need to be placed on the guide rail 20, and then the guide rail 20 is installed on the shelf. Since the shelves are mostly made of metal, when the electronic tag 2 is close to the metal shelf, it will cause the resonant point of the electronic tag 2 to shift and the return loss to be too large, and the performance of the electronic tag 2 will be seriously degraded. Therefore, in this embodiment, at least one frequency modulation layer 5 can be added between the electronic tag 2 and the shelf to reduce the influence of eddy currents and ensure NFC performance.

[0061] In practical use, the resonant point of electronic tag 2 generally needs to be tuned to around 13.56MHz. As mentioned above, due to the influence of the surrounding environment on the resonant point, the resonant point will shift when electronic tag 2 is placed near a metal shelf. Generally, the presence of metal objects near electronic tag 2 will cause its resonant point to be higher. Therefore, adding a frequency modulation layer 5 is used to shift its resonant point to a lower frequency to ensure that the performance of electronic tag 2 is not affected. The frequency modulation layer 5 can be made of an anti-metal material (wave-absorbing material). The anti-metal material can be a composite material obtained by compounding soft magnetic metals (such as iron-silicon-aluminum soft magnetic metal particles) with resin polymer particles (all of which are existing materials), or other materials with the same function. The specific materials used are not limited here.

[0062] Additionally, it should be noted that the Q value (quality factor) of the resonance determines the loss of the electronic tag 2. A larger Q value results in lower loss and a longer communication distance. However, when the NFC reading coil in the electronic price tag 10 is close to the electronic tag 2, an excessively large Q value will cause the resonant points of both the NFC reading coil in the electronic price tag 10 and the electronic tag 2 to deviate significantly from 13.56MHz, leading to a decrease in signal transmission efficiency. Therefore, it is not recommended that the Q value be too high in this invention. The specific Q value can be set according to the actual structure, and no specific limitation is made. The key is to ensure that the resonant point of the NFC reading coil in the electronic price tag 10 and the electronic tag 2 is around 13.56MHz.

[0063] In one optional embodiment of this utility model, such as Figure 3 and Figure 4 As shown, a protective layer 6 is provided on the base strip 1, covering the outside of the frequency modulation layer 5. When the electronic tag device is in the installed state, the protective layer 6 is on the side closer to the shelf. Since the actual installed state may be in a damp or water-accumulated environment, the addition of the protective layer 6 to the outside of the frequency modulation layer 5 can provide moisture-proof and waterproof protection. The frequency modulation layer 5 can be protected by a protective film or coating.

[0064] Furthermore, the protective layer 6 can be made of, but is not limited to, polyethylene terephthalate (PET), high-density polyethylene (HDPE) or thermoplastic polyurethane (TPE), and its service life can generally be more than 10 years. The protective layer 6 covers the frequency modulation layer 5 and the electronic tag 2 to prevent moisture from entering.

[0065] Furthermore, such as Figure 3 and Figure 4 As shown, the electronic tag 2 and the base strip 1, the electronic tag 2 and the frequency modulation layer 5, and / or the frequency modulation layer 5 and the protective layer 6 can be connected by an adhesive layer 7. The adhesive layer 7 can be, but is not limited to, an organic adhesive layer.

[0066] In one specific embodiment of this utility model, such as Figure 3 As shown, the electronic tag 2 can be packaged using chip direct mounting technology (i.e., COB packaging process), where the bare chip is directly fixed onto the printed circuit board, and then wire bonding is performed to form the electronic tag 2. This type of electronic tag 2 requires organic adhesive layers to be set on the front and back, that is, adhesive layers 7 are set simultaneously between the electronic tag 2 and the base strip 1 and between the electronic tag 2 and the frequency modulation layer 5 for connection, which not only serves the purpose of connection but also provides encapsulation and protection for the electronic tag 2.

[0067] In another specific embodiment of this utility model, such as Figure 4As shown, a self-encapsulated chip can also be used. That is, the coil and chip of the electronic tag 2 are placed on the carrier 8, and the electronic tag 2 is placed on the base strip 1 via the carrier 8. The electronic tag 2 and the carrier 8 are located between the base strip 1 and the frequency modulation layer 5, and are connected to the base strip 1 by an adhesive layer 7. The electronic tag 2 and the carrier 8 are also connected to the frequency modulation layer 5 by an adhesive layer 7. The carrier 8 can be, but is not limited to, another base strip.

[0068] In the above embodiments, the base strip 1 may be made of, but is not limited to, PET (polyethylene terephthalate) or PVC (polyvinyl chloride) materials.

[0069] In this invention, an electronic tag 2 with a modified cyclic redundancy check (CRC) function is selected. By modifying the CRC check, the NFC reading coil in some electronic price tags 10 can be kept silent to prevent accidental triggering. This invention can use a preset wake-up command for the NFC reading coil. Before the wake-up command is matched, the electronic tag 2 remains silent and does not respond. It only starts working after the electronic tag 2 receives a matched wake-up command, thereby achieving the purpose of preventing accidental triggering.

[0070] In one optional embodiment of this utility model, such as Figure 1 and Figure 2 As shown, a QR code identification section 4 is provided on the base strip 1 and near one or both ends of the base strip 1. The QR code identification section 4 can be preset with information such as the number and size of the electronic tags 2 set on the corresponding base strip 1, and can also be preset with the encoding information of the corresponding base strip 1. By recognizing the QR code identification section 4, the encoding information of the base strip 1 and the number and size of the electronic tags 2 set on it can be obtained and uploaded to the data center. Since the setting position of each base strip 1 corresponds to the shelf one by one, by obtaining the relevant information of the base strip 1 and the electronic tags 2 on it, the position information of the electronic tags 2 can be obtained, and thus the product information at the corresponding position can be obtained.

[0071] The QR code label 4 can be set on the base strip 1 by laser engraving or affixing.

[0072] It should be noted that the electronic tag 2 in this utility model can be the aforementioned NFC tag, or it can be an RFID tag, etc. When the electronic tag 2 is an RFID tag, the electronic tag system (RFID TAG system) with positioning function can read the encoded information in the electronic tag 2 (RFID TAG) through the RFID reader coil in the electronic price tag 10.

[0073] The features and advantages of this electronic tag device are:

[0074] 1. This electronic tag device, by arranging multiple electronic tags 2 on a base strip 1, ensures that the electronic price tag 10 set within the range of the base strip 1 has half or more of its projection on the base strip 1 overlapping with the projection of the electronic price tag 10 on the base strip 1 at any position. This ensures that the NFC reading coil in the electronic price tag 10 can always accurately read the encoded information in the electronic tag 2 at the corresponding position, thereby achieving accurate positioning of the electronic price tag 10 and ensuring accurate display of product information at the corresponding position by the electronic price tag 10.

[0075] Second, the electronic tag device, through the setting of the frequency modulation layer 5, can ensure that when installed on the shelf, the performance of the electronic tag 2 will not be affected by the resonant point offset or excessive return loss.

[0076] Third, the electronic tag device, through the setting of protective layer 6, can play a protective role such as moisture-proof and waterproof, and extend the service life of electronic tag 2.

[0077] Implementation Method 2

[0078] like Figure 5 As shown, this utility model provides a system with positioning function, which includes a guide rail 20, an electronic price tag 10, and the aforementioned electronic tag device 30. The guide rail 20 has a channel 2001 extending along a length direction, and the guide rail 20 can be installed on a shelf by a snap-fit ​​structure. The electronic price tag 10 is disposed on the guide rail 20, and the electronic tag device 30 is disposed in the channel 2001. The projection of the electronic price tag 10 on the base strip 1 of the electronic tag device 30 overlaps with the projection of half or more of at least one electronic tag 2 in the electronic tag device 30 on the base strip 1.

[0079] Furthermore, the electronic tag device 30 extends along the length of the channel 2001, and is sandwiched between the bottom wall of the channel 2001 and the electronic price tag 10. The electronic price tag 10 has an NFC reading coil, which can read the preset information in the electronic tag 2 at the corresponding position.

[0080] In another optional embodiment of this utility model, such as Figure 6As shown, a first extrusion strip 2002 is formed along the length of the guide rail 20, and the electronic tag device 30 and the electronic price tag 10 are respectively located on both sides of the first extrusion strip 2002. A snap-fit ​​strip 2003 can be respectively provided at the upper and lower parts of the guide rail 20. One end of the snap-fit ​​strip 2003 is connected to the body of the guide rail 20, and the other end of the snap-fit ​​strip 2003 has a protrusion that bends or protrudes towards the first extrusion strip 2002. The electronic tag device 30 is placed between the snap-fit ​​strip 2003 and the first extrusion strip 2002. The protrusion on the snap-fit ​​strip 2003 presses the electronic tag device 30 against one side wall of the first extrusion strip 2002.

[0081] In another alternative embodiment of this utility model, such as Figure 7 As shown, a second extrusion bar 2004 and a third extrusion bar 2005 are formed close to each other on the guide rail 20 along its length direction. The second extrusion bar 2004 and the third extrusion bar 2005 can be arranged parallel to each other in the front-back direction of the shelf, and a clamping space is left between the second extrusion bar 2004 and the third extrusion bar 2005. The electronic tag device 30 can be placed in the clamping space between the second extrusion bar 2004 and the third extrusion bar 2005, and the electronic tag device 30 is clamped by the cooperation of the second extrusion bar 2004 and the third extrusion bar 2005.

[0082] It should be noted that, in addition to the above-mentioned guide rail 20 structure and installation method for the electronic tag device 30, other guide rail 20 structures and installation methods for the electronic tag device 30 may also be used, and no limitation is made here.

[0083] The specific implementation process of this utility model can be as follows:

[0084] First, install the electronic tag device 30 onto the guide rail 20, and then install the guide rail 20 onto the shelf. Next, place the goods on the shelf according to the preset positions. Then, install the electronic price tag 10 onto the guide rail 20 according to the arrangement of the goods. The NFC reading coil of the electronic price tag 10 reads the encoding information of the electronic tag 2 at the corresponding position, and transmits its own ID and the read encoding information of the electronic tag 2 to the back-end server through the base station. The back-end server can send the above information to the electronic price tag 10 according to the pre-stored position information of the electronic tag 2 and the matching product information at the corresponding position. The electronic price tag 10 can then display the correct product information.

[0085] The positioning system of this utility model has the same features and advantages as the above-mentioned electronic tag device, which will not be repeated here.

[0086] It should be noted that in the description of this application, the terms "first," "second," etc., are used only for descriptive purposes and to distinguish similar objects; there is no order between them, nor should they be construed as indicating or implying relative importance. Furthermore, in the description of this application, unless otherwise stated, "multiple" means two or more.

[0087] The various embodiments described in this specification are presented in a progressive manner. The same or similar parts between the embodiments can be referred to each other. Each embodiment focuses on the differences from other embodiments.

[0088] The above are merely several embodiments of this utility model.
