Description

Technical Field

[0001] This invention belongs to the field of electronic tag technology, and specifically relates to an electronic tag with stable signal transmission. Background Technology

[0002] In existing supermarkets, paper or plastic labels are commonly used to display product information. However, this is cumbersome and time-consuming when changing products or adjusting prices in large quantities, consuming a lot of manpower and resources. Furthermore, paper or plastic labels are mostly non-recyclable, have low reuse rates, are not environmentally friendly, and have poor overall effectiveness.

[0003] Therefore, electronic tags have emerged, which feature digital display and reusability. However, most existing electronic tags transmit information through a single base station to complete functions such as tag updates. But when a base station is responsible for too many electronic tags, it can cause data transmission congestion, resulting in asynchronous tag updates, a certain delay, and unstable transmission signals.

[0004] Therefore, further improvements will be made to address the aforementioned technical issues. Summary of the Invention

[0005] The main objective of this invention is to provide an electronic tag with stable signal transmission. It uses a base station paired with several transmission gateways to distribute the transmission pressure downlink to each transmission gateway. The transmission gateways then issue tag update instructions to each covered electronic tag. This total-to-partition transmission method ensures the update speed and signal transmission stability of each electronic tag.

[0006] Another objective of this invention is to provide an electronic tag with stable signal transmission. This tag uses a sensing module to detect in real time whether a human body is present within the sensing range of the electronic tag. If a human body is present, the power module is driven to switch to the normal working state, and the data is displayed through the display module. Otherwise, the power module is in a low-power mode, and the display module does not display data. This tag has the advantages of low power consumption, long service life, and high security.

[0007] To achieve the above objectives, the present invention provides an electronic tag with stable signal transmission, comprising a control module, a display module, a transmission module, and a power supply module (for power supply), wherein:

[0008] Within the signal coverage area of ​​the base station, the area is divided into regions (e.g., daily necessities area, aquatic products area, fruit area, etc.), and each region is equipped with at least one transmission gateway. The base station issues price tag update instructions to each transmission gateway as needed, so that each transmission gateway transmits the price tag update instructions to the transmission module of each electronic tag according to the transmission model logic.

[0009] The transmission module receives the display data corresponding to the price tag update instruction and transmits the display data to the display module through the control module, so that the display module displays the updated display data.

[0010] As a further preferred technical solution to the above technical solution, for the transmission model logic, let the electronic tag covered by only one transmission gateway be the first tag, let the electronic tag covered by two transmission gateways be the second tag, and let the electronic tag covered by at least three transmission gateways be the third tag, wherein:

[0011] The transmission gateway is located at the center of the coverage area. It calculates the distance from the electronic price tag within the coverage area of ​​each transmission gateway to that transmission gateway and transmits the distance data of all electronic price tags to the base station.

[0012] Before issuing each price tag update instruction, the base station calculates the number of the first, second, and third tags within the coverage area of ​​each transmission gateway, where:

[0013] For the first tag, only the transmission gateway covering the first tag issues the tag update instruction;

[0014] For the second tag, firstly, calculate the number of first tags that the two transmission gateways covering the second tag need to transmit, and sort them in order of quantity. If the number of first tags that the two transmission gateways need to transmit is within a preset difference range, the second tag is updated by the transmission gateway that is closer to the first tag. Otherwise, the second tag is updated by the transmission gateway that needs to transmit fewer first tags. Furthermore, if the total number of second tags (first tags plus second tags) required by the transmission gateway that needs to transmit fewer first tags exceeds a preset difference from the number of first tags initially required by the transmission gateway that needs to transmit more first tags, the excess second tags are updated by the transmission gateway with the smaller total number of tags required (ensuring a balance in the number of electronic tags transmitted by the two transmission gateways). (As a ratio, assume the first transmission gateway needs to transmit 100 first tags, and the second gateway needs to transmit...) If 102 first tags are transmitted, then the number of first tags that each gateway needs to transmit is within a preset range. For the second tags that are covered by both gateways, the closer gateway will transmit them, thus improving the data update speed of the electronic tags. However, if we assume that the first gateway needs to transmit 100 first tags and the second gateway needs to transmit 500 first tags, and the difference in the number of first tags exceeds a preset range, then although some second tags in the shared coverage are closer to the second gateway, the second gateway still needs to transmit 500 first tags simultaneously, causing some data congestion. Therefore, the first gateway, which is slightly farther away but needs to transmit fewer first tags, will issue enhanced update commands for the shared second tags. This ensures the update speed of the second tags while alleviating the transmission pressure on the second gateway, thus ensuring the update speed of the first tags within the second gateway.

[0015] For the third tag, firstly calculate the number of first and second tags that all transmission gateways covering the third tag need to transmit, thus obtaining the total number of first and second tags transmitted by the transmission gateways and sorting them in order of quantity. The third tag is issued by the transmission gateway with the fewest total transmissions first. If the total transmission quantity of the transmission gateway with the fewest total transmissions reaches that of the second fewest transmission gateways, the remaining third tags are then evenly distributed again to ensure the current transmission balance of all transmission gateways.

[0016] As a further preferred technical solution to the above technical solution, the electronic tag with stable signal transmission also has a sensing module. (When the supermarket is open for business) The sensing module determines whether human body detection is required based on preset requirements (because some electronic tags need to be displayed in real time regardless of whether there are people around, while some electronic tags can remain blank when no one is present to save power). (When sensing is required) When the human body detection result indicates that a human body has been detected, the power module switches from a low-power state to a regular working state (in the low-power state, the sensing module is working (or the working time is set to the supermarket's business hours, etc.), and can detect whether there is a human body within a preset distance. If so, it drives the power module to switch to a regular working state, thereby supplying power to the control module, display module, etc.). Thus, the control module displays the display data stored in the storage unit through the display module.

[0017] As a further preferred technical solution to the above technical solution, when the power module is in a low-power state and a human body is detected for the first time within the preset (sensing) range of the sensing module, the display module displays the display data. As long as a human body is present within the preset range of the sensing module, the power module remains in a normal working state, wherein:

[0018] When there is no human body within the preset range of the sensing module, the power module switches from the normal working state to the low power state after the first preset time period when the last human body leaves the preset range, until the next human body enters the preset range of the sensing module. If another human body enters the preset range within the first preset time period, the first preset time period will no longer be counted until the last person in the preset range leaves, at which point the first preset time period will start counting again.

[0019] As a further preferred technical solution to the above technical solution, each time a human body is detected entering the boundary of the preset range of the sensing module, it is marked as a human body detection record. After a second preset time period, the human body detection record is transmitted to the control module, so that the control module transmits the human body detection record to the base station (through the transmission gateway) through the transmission module. Thus, the base station obtains the human body detection records of all electronic tags within its coverage area. The base station then transmits the human body detection record of each electronic tag to the background management system for data processing and analysis, thereby obtaining customer flow data corresponding to each electronic tag (which can then be used to analyze which products sell well and why which products have low customer flow, etc.).

[0020] As a further preferred technical solution to the above technical solution, the electronic tag with stable signal transmission is also equipped with a face detection module. When the power module is in the formal working state, when the face detection module detects a human body facing the electronic tag (the human body detection records within the preset range are not accurate enough and will have some errors; some customers may just pass by without browsing, but will still be counted as a record, while by detecting a face facing the tag, it is more likely to be determined that the customer is browsing the product corresponding to the current electronic tag, thereby improving the accuracy of the human body detection record for each electronic tag), it marks it as a human body detection record and transmits the human body detection record to the control module after a second preset time period, so that the control module transmits the human body detection record to the base station through the transmission module, so that the base station obtains the human body detection records of all electronic tags within its coverage area. The base station then transmits the human body detection record of each electronic tag to the background management system for data processing and analysis, thereby obtaining customer flow data corresponding to each electronic tag (which can then be used to analyze which products sell well and which products have low customer flow, etc.).

[0021] As a further preferred technical solution to the above technical solution, each electronic tag is managed through a blockchain system. Price tag update instructions issued by the base station are transmitted to each electronic tag in the corresponding area via a transmission gateway. (If all electronic tags within the coverage area of ​​the base station gateway were to receive update instructions through the base station gateway, the output would be too large at once, causing data congestion and preventing timely updates for each electronic tag. Using a transmission gateway reduces data congestion at the base station gateway and improves the update speed of the electronic tags.) Wherein:

[0022] Each transmission gateway is designated as a master node and each electronic tag as a child node. Each master node acts as a propagation node to transmit the tag update instructions issued by the base station gateway (using blockchain technology, it is impossible for a single electronic tag to be tampered with, thus improving the security of the electronic tag).

[0024] The following description is intended to disclose the present invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0025] In the preferred embodiments of the present invention, those skilled in the art should note that the background management system and the like involved in the present invention can be considered as prior art.

[0026] Preferred embodiment.

[0027] This invention discloses an electronic tag with stable signal transmission. The electronic tag includes a control module, a display module, a transmission module, and a power supply module (for power supply), wherein:

[0028] Within the signal coverage area of ​​the base station, the area is divided into regions (e.g., daily necessities area, aquatic products area, fruit area, etc.), and each region is equipped with at least one transmission gateway. The base station issues price tag update instructions to each transmission gateway as needed, so that each transmission gateway transmits the price tag update instructions to the transmission module of each electronic tag according to the transmission model logic.

[0029] The transmission module receives the display data corresponding to the price tag update instruction and transmits the display data to the display module through the control module, so that the display module displays the updated display data.

[0030] Specifically, for the aforementioned transmission model logic, let the electronic tag covered by only one transmission gateway be the first tag, the electronic tag covered by two transmission gateways be the second tag, and the electronic tag covered by at least three transmission gateways be the third tag, wherein:

[0031] The transmission gateway is located at the center of the coverage area. It calculates the distance from the electronic price tag within the coverage area of ​​each transmission gateway to that transmission gateway and transmits the distance data of all electronic price tags to the base station.

[0032] Before issuing each price tag update instruction, the base station calculates the number of the first, second, and third tags within the coverage area of ​​each transmission gateway, where:

[0033] For the first tag, only the transmission gateway covering the first tag issues the tag update instruction;

[0034] For the second tag, firstly, calculate the number of first tags that the two transmission gateways covering the second tag need to transmit, and sort them in order of quantity. If the number of first tags that the two transmission gateways need to transmit is within a preset difference range, the second tag is updated by the transmission gateway that is closer to the first tag. Otherwise, the second tag is updated by the transmission gateway that needs to transmit fewer first tags. Furthermore, if the total number of second tags (first tags plus second tags) required by the transmission gateway that needs to transmit fewer first tags exceeds a preset difference from the number of first tags initially required by the transmission gateway that needs to transmit more first tags, the excess second tags are updated by the transmission gateway with the smaller total number of tags required (ensuring a balance in the number of electronic tags transmitted by the two transmission gateways). (As a ratio, assume the first transmission gateway needs to transmit 100 first tags, and the second gateway needs to transmit...) If 102 first tags are transmitted, then the number of first tags that each gateway needs to transmit is within a preset range. For the second tags that are covered by both gateways, the closer gateway will transmit them, thus improving the data update speed of the electronic tags. However, if we assume that the first gateway needs to transmit 100 first tags and the second gateway needs to transmit 500 first tags, and the difference in the number of first tags exceeds a preset range, then although some second tags in the shared coverage are closer to the second gateway, the second gateway still needs to transmit 500 first tags simultaneously, causing some data congestion. Therefore, the first gateway, which is slightly farther away but needs to transmit fewer first tags, will issue enhanced update commands for the shared second tags. This ensures the update speed of the second tags while alleviating the transmission pressure on the second gateway, thus ensuring the update speed of the first tags within the second gateway.

[0035] For the third tag, firstly calculate the number of first and second tags that all transmission gateways covering the third tag need to transmit, thus obtaining the total number of first and second tags transmitted by the transmission gateways and sorting them in order of quantity. The third tag is issued by the transmission gateway with the fewest total transmissions first. If the total transmission quantity of the transmission gateway with the fewest total transmissions reaches that of the second fewest transmission gateways, the remaining third tags are then evenly distributed again to ensure the current transmission balance of all transmission gateways.

[0036] More specifically, the electronic tag with stable signal transmission also has a sensing module. (When the supermarket is open for business) The sensing module determines whether human body detection is needed based on preset requirements (because some electronic tags need to display in real time regardless of whether there are people around, while some electronic tags can remain blank when no one is present to save power). (When sensing is needed) When the human body detection result indicates that a human body has been detected, the power module switches from a low-power state to a regular working state (in the low-power state, the sensing module is working (or the working time is set to the supermarket's business hours, etc.), and can detect whether there is a human body within a preset distance. If so, it drives the power module to switch to a regular working state, thereby supplying power to the control module, display module, etc.). Thus, the control module displays the display data stored in the storage unit through the display module.

[0037] Furthermore, when the power module is in a low-power state and a human body is detected for the first time within the preset (sensing) range of the sensing module, the display module displays the data. As long as a human body is present within the preset range of the sensing module, the power module remains in normal working state.

[0038] When there is no human body within the preset range of the sensing module, the power module switches from the normal working state to the low power state after the first preset time period when the last human body leaves the preset range, until the next human body enters the preset range of the sensing module. If another human body enters the preset range within the first preset time period, the first preset time period will no longer be counted until the last person in the preset range leaves, at which point the first preset time period will start counting again.

[0039] Furthermore, each time a human body is detected entering the preset range of the sensing module, it is marked as a human body detection record. After a second preset time period, the human body detection record is transmitted to the control module, so that the control module transmits the human body detection record to the base station (through the transmission gateway) via the transmission module.

The base station then transmits the human body detection record of each electronic tag to the background management system for data processing and analysis, thereby obtaining customer flow data corresponding to each electronic tag (which can then be used to analyze which products sell well and why which products have low customer flow, etc.).

[0040] Preferably, the electronic tag with stable signal transmission is also equipped with a face detection module. When the power module is in normal working state, when the face detection module detects a human body facing the electronic tag (the human body detection records within the preset range are not accurate enough and will have some errors; some customers may just pass by without browsing, but will still be counted as a record, while by detecting a face facing the tag, it is more likely to determine that the customer is browsing the product corresponding to the current electronic tag, thereby improving the accuracy of the human body detection record for each electronic tag), it marks it as a human body detection record and transmits the human body detection record to the control module after a second preset time period, so that the control module transmits the human body detection record to the base station through the transmission module, so that the base station obtains the human body detection records of all electronic tags within its coverage area. The base station then transmits the human body detection record of each electronic tag to the background management system for data processing and analysis, thereby obtaining customer flow data corresponding to each electronic tag (which can then be used to analyze which products sell well and which products have low customer flow, etc.).

[0041] Preferably, each electronic tag is managed through a blockchain system. Price tag update instructions issued by the base station are transmitted to each electronic tag in the corresponding area via a transmission gateway. (If all electronic tags within the coverage area of ​​the base station gateway receive update instructions through the base station gateway, the output will be too large at once, causing data congestion and preventing timely updates for each electronic tag. Using a transmission gateway reduces data congestion at the base station gateway and improves the update speed of the electronic tags.)

[0042] Each transmission gateway is designated as a master node and each electronic tag as a child node. Each master node acts as a propagation node to transmit the tag update instructions issued by the base station gateway (using blockchain technology, it is impossible for a single electronic tag to be tampered with, thus improving the security of the electronic tag).
