A detailed description follows.

[0040] Embodiment one: in this embodiment, the electronic price tag is not powered by a battery.

[0041] Figure 2 Structure of the electronic price tag system in the embodiment of the application Figure 2 As shown in the figure, the system comprises: a shelf layer edge accessory and a shelf layer edge master circuit; wherein: Figure 2

[0042] The shelf layer edge accessory comprises: an accessory body 11 arranged along the edge of the shelf, used for mounting a plurality of electronic price tags 2; a plurality of accessory NFC antenna units 12 arranged along the accessory body, used for transmitting energy and task instructions to the mounted electronic price tags when the antenna selection circuit 13 is connected with any accessory NFC antenna unit 12; and the antenna selection circuit 13 connected with any accessory NFC antenna unit;

[0043] The shelf layer edge master circuit 3 comprises: a connection with the antenna selection circuit 13, used for controlling the antenna selection circuit 13 to select the connection with any accessory NFC antenna unit 12, so that the shelf layer edge master circuit 3 transmits energy through the connected accessory NFC antenna unit to provide a preset working power for the electronic price tag at the position corresponding to the accessory NFC antenna unit to implement different tasks, and the shelf layer edge master circuit 3 performs wireless communication with the electronic price tag at the position through the connected accessory NFC antenna unit, so that the electronic price tag implements different tasks according to different task instructions.

[0044] The electronic price tag system provided by the embodiment of the application: through the shelf layer edge master circuit, the antenna selection circuit of the shelf layer edge accessory (the electronic price tag mounting device of the shelf layer edge) is controlled to work, and any accessory NFC antenna unit is connected, energy and task instructions are transmitted to the mounted electronic price tag, so that the shelf layer edge master circuit transmits energy through the connected accessory NFC antenna unit to provide a preset working power for the electronic price tag at the position corresponding to the accessory NFC antenna unit to implement different tasks, and the shelf layer edge master circuit performs wireless communication with the electronic price tag at the position through the connected accessory NFC antenna unit, so that the electronic price tag implements different tasks according to different task instructions. A brand-new electronic price tag system architecture, power supply method and communication scheme can be provided, low-carbon electronic price tag work is realized, interference of the wireless channel is reduced, and communication efficiency is improved. The system will be described in detail below.

[0045] ​In a specific implementation, the shelf edge accessory includes a plurality of NFC antenna units, i.e., accessory NFC antenna units, and an antenna selection circuit for selecting the antenna units. The shelf edge master circuit includes a master wireless communication chip for controlling the antenna selection circuit, and an NFC reader and an NFC tag chip. The ESL is an electronic price label including a display screen, and an NFC antenna and a master circuit, which can receive power transmitted by the accessory NFC antenna units of the shelf edge accessory through the NFC antenna, and communicate with the shelf edge master circuit through the NFC antenna. The ESL uses an electronic paper display (EPD) technology, which can display text and images like paper, and does not need continuous power supply, but only consumes power when the display content is changed.

[0046] In an embodiment, the ESL is not powered by a battery, and the power for each operation of the ESL is received by the ESL through the NFC antenna of the ESL from the accessory NFC antenna units of the shelf edge accessory. Therefore, it is important to accurately control the power output by the NFC reader of the shelf edge master circuit to only one of the plurality of accessory NFC antenna units of the shelf edge accessory. This is a key to ensure that the power is effectively transmitted and utilized, and the ESL without communication and business needs does not need to be powered. Because the position of the NFC antenna corresponding to the ESL is known, the antenna selection circuit can accurately control the power provided to the NFC antenna, thereby efficiently controlling the power provided to each ESL.

[0047] In an embodiment, the shelf edge accessory in the embodiment of the present application can be adjusted in length, thereby improving flexibility.

[0048] In an embodiment, as shown in FIG. 3, in the embodiment of the present application, there can be 10 wires between the shelf edge accessory and the shelf edge master circuit, and a fixed point card point between the accessory body and the accessory NFC antenna unit 12. Of course, the number of wires and card points can be adjusted according to actual scenarios.

[0049] In an embodiment, the accessory NFC antenna units in the embodiment of the present application are uniformly distributed and fixed at the card points.

[0050] In an embodiment, as shown in FIG. 3, in the embodiment of the present application, there can be 10 wires between the shelf edge accessory and the shelf edge master circuit, and a fixed point card point between the accessory body and the accessory NFC antenna unit 12. Of course, the number of wires and card points can be adjusted according to actual scenarios. Figure 3 As shown in FIG. 4, the antenna selection circuit 13 includes a plurality of selection switches 131, each of which is connected to a plurality of accessory NFC antenna units 12. In a cascading manner, the output end of a previous selection switch is connected to the input end of a subsequent selection switch.

[0051] In a specific implementation, as shown in FIG. 5, the shelf edge accessory includes a plurality of NFC antenna units, i.e., accessory NFC antenna units, and an antenna selection circuit for selecting the antenna units. The shelf edge master circuit includes a master wireless communication chip for controlling the antenna selection circuit, and an NFC reader and an NFC tag chip. The ESL is an electronic price label including a display screen, and an NFC antenna and a master circuit, which can receive power transmitted by the accessory NFC antenna units of the shelf edge accessory through the NFC antenna, and communicate with the shelf edge master circuit through the NFC antenna. The ESL uses an electronic paper display (EPD) technology, which can display text and images like paper, and does not need continuous power supply, but only consumes power when the display content is changed. Figure 3As shown, the antenna selection circuit is a four-to-one circuit as an example, and can also be eight-to-one or more, and the number of control lines between the shelf edge master circuit and the shelf edge fittings will change accordingly. In a cascading manner, one output of a previous switch is linked to the input signal of the next stage switch, so that more antennas can be selected individually along the strip structure of the shelf edge fittings with fewer wiring numbers.

[0057] In one embodiment, the wireless communication between the connected accessory NFC antenna unit and the electronic price label at the corresponding position can include: the NFC reader 35 reads the identification of the electronic price label at the corresponding position of the connected accessory NFC antenna unit, and sends the task instructions to the electronic price label at the corresponding position through the connected accessory NFC antenna unit.

[0061] In some scenarios, the identification of the shelf edge master circuit 3 needs to be obtained in the implementation. Of course, the NFC tag chip 34 cooperates with the master circuit NFC antenna unit 33 to obtain the identification of the new electronic price tag to be installed, the binding task instruction, and the identification of the electronic price tag to be positioned through the handheld terminal.

[0081] The main working process of the new electronic price tag system architecture will be introduced below. Figures 1 to 3

[0082] 1. Registration

[0083] The ESL (electronic price tag) is installed on a shelf edge accessory, and the shelf edge master circuit can discover in two ways:

[0084] The first way is that the shelf edge master circuit periodically queries and reads whether there is a new ESL ID (electronic price tag identifier) at each accessory NFC antenna unit position, and determines the position at the same time.

[0085] That is, in an embodiment, after the master wireless communication chip provides working power for the electronic price tag at the corresponding position of the accessory NFC unit through the NFC reader, the master wireless communication chip sends different task instructions to the NFC reader, including: after the master wireless communication chip provides working power for the electronic price tag at the corresponding position of the accessory NFC unit through the NFC reader, the master wireless communication chip periodically sends query task instructions to the NFC reader;

[0086] According to the different task instructions, the NFC reader performs wireless communication with the electronic price tag at the corresponding position through the connected accessory NFC antenna unit, so that the electronic price tag implements different tasks according to the different task instructions, including:

[0087] The NFC reader sends the query task instructions to the connected accessory NFC antenna unit; the connected accessory NFC antenna unit is used to obtain the identifier of the new electronic price tag according to the query task instructions;

[0088] The NFC reader reads the identifier of the new electronic price tag obtained by the connected accessory NFC antenna unit and sends it to the master wireless communication chip;

[0089] The working method can further include: ​

[0090] The master wireless communication chip determines the location information of the new electronic price tag after receiving the new electronic price tag identification, initiates communication with the base station, and reports the new electronic price tag identification and its location information to the electronic price tag background server through the base station; the electronic price tag background server registers the new electronic price tag into the network according to the new electronic price tag identification and its location information, that is, all subsequent messages that the network hopes to send to this electronic price tag are transmitted through the master circuit.

[0091] In a specific implementation, the master circuit can store the relationship between the electronic price tag identification and the location information of the electronic price tag. After receiving the new electronic price tag identification, the master wireless communication chip can search for the corresponding location information of the new electronic price tag identification in the relationship.

[0092] Secondly, when the PDA or other handheld terminal touches the edge of the master circuit of the shelf, the master circuit can directly obtain the ESID through the handheld terminal, and then query the ESLID of the NFC antenna position one by one to determine the location.

[0093] That is, in an embodiment, the above working method can further include:

[0094] When the handheld terminal touches the NFC antenna unit of the master circuit, the master wireless communication chip obtains the new electronic price tag identification to be installed transmitted by the handheld terminal through the NFC tag chip; the master wireless communication chip is connected with the NFC tag chip, and the NFC tag chip is connected with the NFC antenna unit of the master circuit;

[0095] After the NFC reader provides working power for the electronic price tag at the position corresponding to the accessory NFC unit, the master wireless communication chip sends different task instructions to the NFC reader, including: when the new electronic price tag is installed on the accessory body, the master wireless communication chip sends the query task instruction to the NFC reader after the NFC reader provides working power for the electronic price tag at the position corresponding to the accessory NFC unit;

[0096] The NFC reader performs wireless communication with the electronic price tag at the position through the connected accessory NFC antenna unit according to the different task instructions, so that the electronic price tag realizes different tasks according to different task instructions, including:

[0097] The NFC reader sends the query task instruction to the connected accessory NFC antenna unit; the connected accessory NFC antenna unit is used to obtain the identification of the new electronic price tag according to the query task instruction;

[0098] The NFC reader reads the identification of the new electronic price tag obtained by the connected accessory NFC antenna unit and sends it to the master wireless communication chip;

[0099] The working method can further include:

[0100] The master wireless communication chip compares the identification of the electronic price tag read by the NFC card reader with the identification of the new electronic price tag obtained through the handheld terminal, and if they are consistent, determines the position information of the new electronic price tag obtained by the connected accessory NFC antenna unit as the position information of the new electronic price tag, initiatively initiates communication with the base station, and reports the new electronic price tag identification and its position information to the electronic price tag background server through the base station; the electronic price tag background server is configured to register the new electronic price tag into the network according to the new electronic price tag identification and its position information.

[0101] After the shelf edge master circuit obtains the new ESL ID, it initiatively initiates communication with the AP, and reports the ESL ID, its own ID, and other necessary attributes to the network through the AP.

[0102] 2. Binding and updating

[0103] There are two ways to bind the ESL and the goods:

[0104] The first way is that the handheld terminal scans the goods, touches the ESL to read the ESL ID, and then touches the shelf edge master circuit, and transmits the goods ID and the ESL ID to the electronic price tag background server through the communication between the master circuit and the AP of the electronic price tag to establish a binding relationship.

[0105] In the embodiment, when the electronic price tag and the goods are bound, the handheld terminal scans the goods to be bound to obtain the information of the goods to be bound, the handheld terminal touches the electronic price tag to be bound to obtain the information of the electronic price tag to be bound, the handheld terminal sends a binding instruction to the shelf edge master circuit through touching the shelf edge master circuit, the binding instruction includes the information of the goods to be bound and the information of the electronic price tag to be bound, the shelf edge master circuit sends the binding instruction to the electronic price tag background server through the base station, and the electronic price tag background server establishes a relationship between the goods to be bound and the electronic price tag to be bound according to the binding instruction.

[0106] As can be seen from the above, in one embodiment, the working method further includes:

[0108] The master control wireless communication chip sends the binding task instruction to the electronic price tag background server through the base station; and the electronic price tag background server is used for establishing the binding relationship between the to-be-bound commodity and the to-be-bound electronic price tag according to the binding task instruction.

[0109] Secondly, after the handheld terminal scans the commodity, the ESL ID is read by touching the ESL, and then the instruction is sent to the electronic price tag background server through the WIFI network or the mobile network to establish the binding relationship.

[0110] In the specific implementation, when the electronic price tag and the commodity are bound, the handheld terminal scans the to-be-bound commodity to obtain to-be-bound commodity information; the handheld terminal touches the to-be-bound electronic price tag to obtain to-be-bound electronic price tag information; the handheld terminal sends a binding instruction to the electronic price tag background server through the network; the binding instruction includes the to-be-bound commodity information and the to-be-bound electronic price tag information; and the electronic price tag background server establishes the relationship between the to-be-bound commodity and the to-be-bound electronic price tag according to the binding instruction.

The electronic price tag can not store multiple pages of FLASH space, and all data are stored on the shelf edge master circuit, and the page turning logic is realized on the shelf edge master circuit and then transmitted to each ESL for display.

[0124] Each time the shelf edge master circuit transmits the instruction and data to a certain electronic price tag, it needs to determine that the corresponding NFC antenna is selected and output enough power for the electronic price tag to complete the corresponding operation of the instruction, such as flashing time and screen brushing time, and then the power supply on the accessory NFC antenna unit can be removed.

[0125] The second kind is the page turning and flashing instruction of NFC operation:
