Description

Technical Field

[0001] The present invention belongs to the technical field of electronic tags, and in particular relates to a high-security electronic tag system. Background Art

[0002] On existing supermarket shelves, paper or plastic labels are commonly used to display product information. However, each time a large number of products are replaced or prices are adjusted, it is cumbersome and time-consuming, consuming a lot of manpower and material resources. In addition, paper or plastic labels cannot be recycled, have a low reuse rate, are not environmentally friendly, and the overall effect is poor.

[0003] Therefore, electronic tags have emerged, which have the characteristics of digital display and reuse. However, each existing electronic tag is equipped with a main communication module connected to the base station, which is costly and has no verification during the data transmission process. It is easy to be tampered with and poses a security risk.

[0004] Therefore, further improvements are made to the above problems. Summary of the Invention

[0005] The main purpose of the present invention is to provide a high-security electronic tag system. The main tag is equipped with a main communication module and other secondary tags are equipped with secondary communication modules. Only the main communication module can communicate with the base station, and the rest are transmitted between the secondary communication modules. This greatly reduces the cost by not installing a main communication module on each tag body, and verification is required during the data transmission process to improve security and prevent tampering.

[0006] To achieve the above objectives, the present invention provides a highly secure electronic tag system, comprising a tag body and a shelf, wherein the shelf is provided with a plurality of cargo placement areas for placing goods, and each cargo placement area is provided with a corresponding matching tag body, wherein:

[0007] Sort the tag bodies corresponding to all the cargo placement areas in a preselected area of ​​the shelf (for example, a row or a column of the shelf), and establish wireless communication connections between the tag bodies matching the adjacent cargo placement areas from the beginning to the end of the preselected area (for example, the cargo placement areas and their tag bodies designed from the beginning to the end are sorted and marked as A / B / C / D / E / F in sequence), select one tag body from each tag body as the primary tag and the remaining tag bodies as secondary tags, and determine that the primary tag is located at the end (including the beginning or the end) All paths of the secondary tags (for example, if the above-mentioned tail F is used as the main tag, the path determined by F is the FEDCBA path from F to A. If the above-mentioned C is used as the main tag, the path determined by C is the CBA path from C to A and the CDEF path from C to F). When the tag bodies establish a wireless communication connection between each other, except for the tag body at the end, each tag body stores the identification codes of the two adjacent tag bodies (for example, for C, it stores the identification codes of BD). The main tag is provided with a primary communication module and the secondary tag is provided with a secondary communication module, wherein:

[0008] For the label change instruction issued from the base station (including the change data and verification data of all label bodies that need to be changed), the main communication module receives the label change instruction (after verification) and transmits the label change instruction in sequence through the secondary communication modules of each secondary label according to the determined path. Each time it is transmitted to a node of a secondary label, the label change instruction is verified. If the verification is successful, the data corresponding to the current label change instruction is downloaded to the secondary label, and the data is deleted from the label change instruction and then continued to be transmitted to the next label until the secondary label at the end; if the verification is unsuccessful, the data corresponding to the label change instruction cannot be downloaded to the secondary label, and a fault instruction is generated and transmitted and fed back to the base station in sequence (for example, when the label change instruction is transmitted to C, if the corresponding data contains the identification code of BD, it is matched and the data is downloaded to the label to prevent intrusion and tampering of the label information, thereby improving security. Only the main communication module can communicate with the base station, and the rest are transmitted between the secondary communication modules, so that there is no need to install a main communication module on each label body, which greatly reduces costs);

[0009] For information uploaded from the secondary tag (for example, a fault occurs), the information includes the identification codes of all tags on the path, and only the secondary tags that have passed verification will be forwarded until the initiating secondary tag transmits the information to the main communication module through each secondary communication module along the determined (shortest) path, so that the main communication module uploads the information to the base station (in order to prevent the information uploaded by the tag from being tampered with or actively tampering with the information, the present invention also includes an identification code in the information, and only the tags that have passed verification will be forwarded, thereby improving security).

[0010] As a further preferred technical solution of the above technical solution, an anti-theft device is also included. The tag body includes a processing module, a scanning module, a display module, a wireless module and an anti-theft processing module, wherein:

[0011] After the goods placed in the goods placement area (the tag body is placed on one side of the goods placement area) are selected (i.e., confirmed to be purchased), the identification code of the goods is placed on the scanning module, so that the scanning module scans the selected goods, thereby transmitting the generated scan data to the processing module. After processing, the processing module transmits the purchase information to the display module, so that the display interface of the display module changes from the tag information display interface (displaying price, promotion activities, etc.) to the goods purchase information interface (displaying purchased quantity, price, payment, etc.);

[0012] After the goods purchase information interface receives the payment information, the generated purchase completion data is transmitted to the processing module, so that the processing module, on the one hand, changes the display interface of the display module from the goods purchase information interface to the anti-theft reminder interface (to remind customers to put the goods in a designated place for anti-theft processing), and on the other hand, drives the anti-theft processing module to perform anti-theft processing on the goods located in the anti-theft area and equipped with anti-theft devices (anti-theft strips, etc.) (for example, demagnetize the anti-theft devices) and transmit the anti-theft results to the processing module. (After the anti-theft is successfully removed) the processing module changes the anti-theft reminder interface of the display module to the anti-theft processing completion interface and transmits the successful anti-theft record of the goods to the purchase database of the anti-theft device via the wireless module. The display module changes back to the tag information display interface after a preset time, thereby completing the purchase task through the tag body.

[0013] When the goods pass through the anti-theft device, the anti-theft device first detects the anti-theft device of the goods to determine whether it has been de-thefted by the de-theft processing module. If so, the first detection is completed, otherwise a first alarm message is generated (to prevent someone from directly walking out of the anti-theft device with the goods); after the first detection is completed, the anti-theft device determines whether the current goods are recorded in the purchase database. If so, a second detection is completed, otherwise a second alarm message is generated (to prevent someone from bringing their own de-theft processing device to de-theft the goods, and then walking out of the anti-theft device with the goods, and the second detection is used to protect the goods from theft, thereby improving safety).

[0014] As a further preferred technical solution of the above technical solution, the anti-theft device is provided with a first alarm light and a second alarm light. When the first alarm information is generated, the first alarm light displays the alarm in a first color. When the second alarm information is generated, the second alarm light displays the alarm in a second color (so that the staff who come to check can understand the current alarm situation according to the color).

[0015] As a further preferred technical solution of the above technical solution, the tag body is also provided with a display detection module, which periodically detects the display interface of the display module to determine whether there is an obstruction affecting the display or a display failure occurs on the current display interface. If so, a display alarm message is generated to the processing module, so that the processing module transmits the display alarm message to the background management system through the wireless module (and then notifies the staff to check).

[0017] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0018] In the preferred embodiment of the present invention, those skilled in the art should note that the goods, backend management system, etc. involved in the present invention can be regarded as prior art.

[0019] Preferred embodiment.

[0020] The present invention discloses a high-security electronic tag system, comprising a tag body and a shelf, wherein the shelf is provided with a plurality of cargo placement areas for placing goods and each cargo placement area is provided with a corresponding matching tag body, wherein:

[0021] Sort the tag bodies corresponding to all the cargo placement areas in a preselected area of ​​the shelf (for example, a row or a column of the shelf), and establish wireless communication connections between the tag bodies matching the adjacent cargo placement areas from the beginning to the end of the preselected area (for example, the cargo placement areas and their tag bodies designed from the beginning to the end are sorted and marked as A / B / C / D / E / F in sequence), select one tag body from each tag body as the primary tag and the remaining tag bodies as secondary tags, and determine that the primary tag is located at the end (including the beginning or the end) All paths of the secondary tags (for example, if the above-mentioned tail F is used as the main tag, the path determined by F is the FEDCBA path from F to A. If the above-mentioned C is used as the main tag, the path determined by C is the CBA path from C to A and the CDEF path from C to F). When the tag bodies establish a wireless communication connection between each other, except for the tag body at the end, each tag body stores the identification codes of the two adjacent tag bodies (for example, for C, it stores the identification codes of BD). The main tag is provided with a primary communication module and the secondary tag is provided with a secondary communication module, wherein:

[0022] For the label change instruction issued from the base station (including the change data and verification data of all label bodies that need to be changed), the main communication module receives the label change instruction (after verification) and transmits the label change instruction in sequence through the secondary communication modules of each secondary label according to the determined path. Each time it is transmitted to a node of a secondary label, the label change instruction is verified. If the verification is successful, the data corresponding to the current label change instruction is downloaded to the secondary label, and the data is deleted from the label change instruction and then continued to be transmitted to the next label until the secondary label at the end; if the verification is unsuccessful, the data corresponding to the label change instruction cannot be downloaded to the secondary label, and a fault instruction is generated and transmitted and fed back to the base station in sequence (for example, when the label change instruction is transmitted to C, if the corresponding data contains the identification code of BD, it is matched and the data is downloaded to the label to prevent intrusion and tampering of the label information, thereby improving security. Only the main communication module can communicate with the base station, and the rest are transmitted between the secondary communication modules, so that there is no need to install a main communication module on each label body, which greatly reduces costs);

[0023] For information uploaded from the secondary tag (for example, a fault occurs), the information includes the identification codes of all tags on the path, and only the secondary tags that have passed verification will be forwarded until the initiating secondary tag transmits the information to the main communication module through each secondary communication module along the determined (shortest) path, so that the main communication module uploads the information to the base station (in order to prevent the information uploaded by the tag from being tampered with or actively tampering with the information, the present invention also includes an identification code in the information, and only the tags that have passed verification will be forwarded, thereby improving security).

[0024] Specifically, it also includes an anti-theft device, and the tag body includes a processing module, a scanning module, a display module, a wireless module (i.e., a primary communication module or a secondary communication module) and an anti-theft processing module, wherein:

[0025] After the goods placed in the goods placement area (the tag body is placed on one side of the goods placement area) are selected (i.e., confirmed to be purchased), the identification code of the goods is placed on the scanning module, so that the scanning module scans the selected goods, thereby transmitting the generated scan data to the processing module. After processing, the processing module transmits the purchase information to the display module, so that the display interface of the display module changes from the tag information display interface (displaying price, promotion activities, etc.) to the goods purchase information interface (displaying purchased quantity, price, payment, etc.);

[0026] After the goods purchase information interface receives the payment information, the generated purchase completion data is transmitted to the processing module, so that the processing module, on the one hand, changes the display interface of the display module from the goods purchase information interface to the anti-theft reminder interface (to remind customers to put the goods in a designated place for anti-theft processing), and on the other hand, drives the anti-theft processing module to perform anti-theft processing on the goods located in the anti-theft area and equipped with anti-theft devices (anti-theft strips, etc.) (for example, demagnetize the anti-theft devices) and transmit the anti-theft results to the processing module. (After the anti-theft is successfully removed) the processing module changes the anti-theft reminder interface of the display module to the anti-theft processing completion interface and transmits the successful anti-theft record of the goods to the purchase database of the anti-theft device via the wireless module (which can be directly transmitted through the secondary communication module or forwarded through the main communication module). The display module changes back to the tag information display interface after a preset time, thereby completing the purchase task through the tag body.

[0027] When the goods pass through the anti-theft device, the anti-theft device first detects the anti-theft device of the goods to determine whether it has been de-thefted by the de-theft processing module. If so, the first detection is completed, otherwise a first alarm message is generated (to prevent someone from directly walking out of the anti-theft device with the goods); after the first detection is completed, the anti-theft device determines whether the current goods are recorded in the purchase database. If so, a second detection is completed, otherwise a second alarm message is generated (to prevent someone from bringing their own de-theft processing device to de-theft the goods, and then walking out of the anti-theft device with the goods, and the second detection is used to protect the goods from theft, thereby improving safety).

[0028] Specifically, the anti-theft device is provided with a first alarm light and a second alarm light. When a first alarm message is generated, the first alarm light displays an alarm in a first color. When a second alarm message is generated, the second alarm light displays an alarm in a second color (so that staff who come to check can understand the current alarm situation based on the color).

[0029] More specifically, the tag body is also provided with a display detection module, which periodically detects the display interface of the display module to determine whether there are any obstructions that affect the display or a display failure occurs on the current display interface. If so, a display alarm message is generated to the processing module, so that the processing module transmits the display alarm message to the background management system through the wireless module (and then notifies the staff to check).

[0030] Furthermore, it also includes several transmission gateways, which accurately locate the specific location of the positioning tag body within the coverage range of the base station through the linkage of the base station, the tag body and the transmission gateway (the transmission gateway is distributed within the coverage range of the base station and is used to realize the data flow between the base station and the tag body), wherein:

[0031] The base station sends a positioning query instruction for the preset tag body (i.e. the tag body to be searched) to each of the transmission gateways, so that each of the transmission gateways broadcasts the gateway broadcast information matching the tag body (including the ID information of the tag body, etc.). When the tag body receives the gateway broadcast information matching itself, the tag body and the surrounding transmission gateways are linked to perform positioning processing according to the positioning model, and the specific location information of the tag body is transmitted to the base station (interacting with the background management system information so that the staff can know the location information of the tag body to be queried) to complete the positioning query task of the tag body initiated by the base station.

[0032] Furthermore, the location query task of the tag body initiated by the base station is specifically implemented as follows:

[0033] When each of the transmission gateways broadcasts gateway broadcast information that matches the tag body, each tag body within the transmission gateway broadcast distance receives the gateway broadcast information and matches the gateway broadcast information with its own information to determine whether the tag body required for positioning query in the gateway broadcast information is itself. If so, the tag body actively sends feedback information and interacts with the surrounding transmission gateways to perform positioning processing according to the positioning model; otherwise, the tag body is in a silent state (i.e., no feedback information is sent). For the positioning processing of the positioning model,

[0034] The tag body uses the nearest transmission gateway as the master node according to the strength of the gateway broadcast information received from each transmission gateway, so that the transmission node establishes a positioning node combination with itself as the master node. The positioning node combination includes the master node, the first ranging node, the second ranging node and the backup node (all of the above nodes are transmission gateways). The specific location of the tag body required for positioning query is transmitted to the base station through the positioning node combination.

[0035] Preferably, the positioning node combination for the positioning query task is specifically implemented as follows:

[0036] After the master node is triggered, it drives the first ranging node and the second ranging node to monitor the position of the tag body, thereby obtaining the position information of the first ranging node and the second ranging node respectively with the tag body and transmitting the position information to the master node, so that the master node obtains the specific position of the tag body after calculation and processing and transmits the specific position to the base station.

[0037] Preferably, when the tag body encounters a fault (for example, when the anti-theft processing module fails to process the anti-theft), it is necessary to notify the staff to check, so it is necessary to actively send the location to the base station and then notify, which is specifically implemented as follows:

[0038] When encountering a fault, the tag body broadcasts tag broadcast information that matches itself (including its own ID information, etc.). The tag body and the surrounding transmission gateways are linked to perform positioning processing according to the positioning model, and the specific location information of the tag body is transmitted to the base station to complete the periodic positioning upload task initiated by the tag body and transmitted to the base station.

[0039] The specific implementation of the periodic positioning upload task initiated by the tag body and transmitted to the base station is as follows:

[0040] Each transmission gateway is matched with the transmission gateway closest to it according to the strength of the tag broadcast information received from the tag body, and the transmission gateway is used as the master node, so that the transmission node establishes a positioning node combination with itself as the master node. The positioning node combination includes the master node, the first ranging node, the second ranging node and the backup node (all of the above nodes are transmission gateways), and the specific location of the tag body required for positioning query is transmitted to the base station through the positioning node combination.

[0041] The positioning node combination for the fault active upload task is specifically implemented as follows:

[0042] After the master node is triggered, it drives the first ranging node and the second ranging node to monitor the position of the tag body, thereby obtaining the position information of the first ranging node and the second ranging node respectively with the tag body and transmitting the position information to the master node, so that the master node obtains the specific position of the tag body after calculation and processing and transmits the specific position to the base station.

[0043] If the first ranging node and the second ranging node are working normally, the position of the tag body is monitored by the first ranging node and the second ranging node;

[0044] If any of the first ranging node and the second ranging node fails (does not work), the standby node replaces the failed ranging node and the normally working ranging node and the standby node monitor the location of the tag body;

[0045] If both the first ranging node and the second ranging node fail to work, the backup node and the main node replace the failed ranging nodes and the backup node and the main node monitor the location of the tag body.

[0046] It is worth mentioning that the standby node determines whether a monitoring failure (ie, a failure in monitoring accuracy) occurs during the position monitoring process of the first ranging node and the second ranging node. If a monitoring failure occurs, the standby node directly replaces the first ranging node, otherwise, the standby node does not replace the first ranging node.

[0047] It is worth mentioning that the technical features of the goods, back-end management system, etc. involved in the patent application of this invention should be regarded as prior art. The specific structure, working principle and possible control method and spatial layout method of these technical features can be selected by conventional choices in the field, and should not be regarded as the inventive point of the patent of this invention. The patent of this invention will not be further elaborated.

[0048] For those skilled in the art, it is still possible to modify the technical solutions described in the aforementioned embodiments, or to make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
