Description

Technical Field

[0001] The present invention relates to the technical field of shelf management, and in particular, to a method, device, equipment and medium for positioning an electronic price tag. Background Art

[0002] At present, the determination of the position of an electronic price tag (usually including the shelf number of the shelf where it is located, the layer number of the layer where it is located, and the specific position on that layer) mainly relies on a rail-powered electronic price tag system to achieve. The rail-powered electronic price tag system needs to deploy a rail on each layer of each shelf. The electronic price tag is hard-connected to the rail-powered electronic price tag system through a contact, so that the rail can locate the electronic price tag through the occupied contact.

[0003] Although the rail-powered electronic price tag system can achieve automatic positioning of the electronic price tag, on the one hand, the structure of the rail-powered electronic price tag system is relatively complex, resulting in too high installation and maintenance costs; on the other hand, the rail-powered electronic price tag system needs to be turned on for a long time, and the energy consumption cost is also high. Summary of the Invention

[0004] The present invention provides a method, device, equipment and medium for positioning an electronic price tag to reduce the positioning cost of automatic positioning of the electronic price tag.

[0005] According to one aspect of the present invention, a method for positioning an electronic price tag is provided, including:

[0006] After determining that the current moving state is stopped, obtaining the tag information of the nearby positioning wireless tags; the positioning wireless tags are passive wireless tags with fixed positions on the shelf;

[0007] Determining a target positioning wireless tag from the positioning wireless tags according to the tag information;

[0008] Reading the position code pre-stored in the target positioning wireless tag and reporting the position code to the server.

[0015] According to another aspect of the present invention, there is provided a computer-readable storage medium storing computer instructions for implementing the positioning method of the electronic price tag according to any embodiment of the present invention when executed by a processor.

[0016] In the embodiment of the present invention, the positioning of the electronic price tag is only performed after it is determined that the current moving state is a stopped movement, which avoids the problem of excessive power consumption caused by the continuous reception of the position information of nearby wireless tags and the continuous reporting of the position information during the operation of the electronic price tag. At the same time, positioning wireless tags are deployed on the shelf to automatically position the electronic price tag instead of the guide rail-powered electronic price tag system.

[0025] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] It should be noted that the terms "first", "second", etc. in the present invention are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0027] Figure 1A It is a flowchart of a positioning method for an electronic price tag according to an embodiment of the present invention. This embodiment is applicable to the situation where a large number of passive positioning wireless tags are deployed on a shelf to replace the existing rail-powered electronic price tag system. This method can be executed by a positioning device for an electronic price tag, and this device can be implemented in the form of hardware and / or software. This device can be configured in an electronic device with corresponding data processing capabilities, such as an active electronic price tag. As Figure 1A shown, this method includes:

[0028] S110. After determining that the current movement state is stopped, obtain the tag information of the nearby positioning wireless tags.

[0029] S120. Determine the target positioning wireless tag from the positioning wireless tags according to the tag information.

[0030] S130. Read the position code pre-stored in the target positioning wireless tag and report the position code to the server.

[0031] Among them, the positioning wireless tag is a passive wireless tag with a fixed position on the shelf. A passive wireless tag refers to a tag that can work without its own power supply. It usually consists of a small chip and an antenna, and can be a passive NFC tag or a passive RFID tag, etc. The tag information includes the UID and signal strength of the positioning wireless tag. The target positioning wireless tag is generally the positioning wireless tag closest to the electronic price tag.

[0032] Specifically, a large number of positioning wireless tags are deployed on the shelf in advance, and according to the location of the positioning wireless tag, its location code of its location is written into the internal storage space to complete the preparation work before positioning.

[0033] The electronic price tag detects its own movement state to determine whether the movement state is in motion or stopped. If the movement state is in motion, the positioning is paused. If the movement state is stopped and this movement state has lasted for a certain period of time, the positioning starts.

[0034] The electronic price tag turns on its own wireless signal (such as NFC) field and scans the nearby passive wireless tags using a customized verification initial value. The wireless signal field generated by the electronic price tag provides the energy required for the passive wireless tag to work, enabling the passive wireless tag to respond to the scan. The passive wireless tags that respond to the scan are determined as the nearby positioning wireless tags. The scanning process will be repeated once or multiple times until the number of scanned positioning wireless tags meets the expectation. During the scanning process, the tag information of each scanned positioning wireless tag is recorded.

[0035] According to the signal strength of each scanned positioning wireless tag, the positioning wireless tag with the highest signal strength is determined as the target positioning wireless tag. According to the UID of the target positioning wireless tag, the position code pre-stored in the target positioning wireless tag is read through the wireless signal field, and the position code and the ESL-ID (i.e., the electronic price tag ID) are reported to the server together, and at the same time, its own wireless signal field is turned off. After receiving the newly reported position code and its UID of the electronic price tag, the server updates the position of the electronic price tag in the server.

[0036] After determining that the current movement state is stopped, the embodiment of the present invention performs the positioning of the electronic price tag, avoiding the problem of excessive power consumption caused by the continuous reception of the position information of nearby wireless tags and the continuous reporting of position information during the operation of the electronic price tag. At the same time, positioning wireless tags are deployed on the shelf to automatically position the electronic price tag instead of the rail-powered electronic price tag system. The deployment of the positioning wireless tag is very simple, without the need to upgrade and transform the existing shelf, and the installation and maintenance costs are very low. Moreover, as a passive device, the energy cost of the positioning wireless tag can be ignored, effectively reducing the positioning cost of the automatic positioning of the electronic price tag.

[0037] Exemplarily, as Figure 1B shown, rows of positioning wireless tags are placed on the rails of the shelf. The electronic price tag can be installed on the rail by means of a buckle, etc., and is located in front of the positioning wireless tag, forming a placement method with the electronic price tag in the front and the positioning wireless tag in the back. According to the predefined coding rule, for the 6 positioning wireless tags shown in the figure, the position codes pre-stored in their interiors from left to right are 010201, 010202, 010203, 010204, 010205, and 010206 respectively. Two items are newly placed on this idle shelf, and the electronic price tags of these two items are also placed in front of the positioning wireless tags shown in the figure.

[0038] For the electronic price tag on the left, only the first positioning wireless tag is scanned during the first scanning process, and this positioning wireless tag is directly determined as the target positioning wireless tag, and the position code in the target positioning wireless tag: 010201 is read, and it is known that it is currently in the 1st position from left to right on the 2nd layer of Shelf No. 1, and this position code and the ESL-ID are reported to the server. After receiving this position code and the ESL-ID, the server knows that this electronic price tag and its corresponding item have been moved to the 1st position from left to right on the 2nd layer of Shelf No. 1, and updates the database accordingly.

[0039] For the electronic price tag on the right, 2 positioning wireless tags are scanned during the first scanning process, and the positioning wireless tag with the stronger signal strength is determined as the target positioning wireless tag, and the position code in the target positioning wireless tag: 010206 is read, and it is known that it is currently in the 6th position from left to right on the 2nd layer of Shelf No. 1, and this position code and the ESL-ID are reported to the server. After receiving this position code and the ESL-ID, the server knows that this electronic price tag and its corresponding item have been moved to the 6th position from left to right on the 2nd layer of Shelf No. 1, and updates the database accordingly.

[0040] Figure 2A The flowchart of a method for positioning an electronic price tag provided by another embodiment of the present invention is optimized and improved on the basis of the above embodiment. AsFigure 2A As shown in the figure, the method includes:

[0041] S210. Track the signal strength of nearby wireless access points; determine the current movement state according to the change trend of the signal strength; the movement state includes moving and stopped moving.

[0042] Specifically, as Figure 2B shown in the figure, there are multiple wireless access points placed in the supermarket. The electronic price tag continuously tracks the signal strength of each wireless access point through the 2.4GHz private protocol, records the initial value and continuous change value of the signal strength of each wireless access point, and analyzes the change trend of the signal strength accordingly. If the change trend is not stable, it is determined that the current state is moving; if the change trend is stable, it is determined that the current state is stopped moving. By tracking the signal strength of nearby wireless access points to determine its own movement state, the electronic price tag does not need to add additional hardware structure, with low implementation cost and low overall power consumption, and the movement state is judged more accurately by the signal strength.

[0043] S220. After determining that the current movement state is stopped moving, turn on the wireless signal field; scan nearby wireless tags according to the customized verification initial value, and determine the wireless tags in response to the scan as the nearby positioning wireless tags.

[0044] S230. If the number of the positioning wireless tags meets the positioning requirements, stop scanning and record the tag information of the positioning wireless tags; if the number of the positioning wireless tags does not meet the positioning requirements, return to execute scanning nearby wireless tags according to the customized verification initial value until the number of the positioning wireless tags meets the analysis requirements.

[0045] Among them, the customized verification initial value is a cyclic redundancy check value specifically set for the positioning wireless tags.

[0046] Specifically, initialize the wireless signal - scanning parameters. For each size of product, there is a set of customized parameters, including the initial value of the transmission power, the final value, the step level, the receiving sensitivity, the receiving noise threshold, the antenna matching resistance - capacitance value, and the whole set of parameters is stored in the form of a table. Since the electronic price tag stores commodity information internally, there is a need for wireless reading and writing (such as NFC reading and writing) by other wireless reading and writing devices (such as NFC reading and writing devices), such as the need to be activated, written with commodity information, and modified with commodity information by the handheld wireless reading and writing device of supermarket employees. Therefore, the electronic price tag itself also has a wireless tag. During positioning, the electronic price tag silences its own wireless tag (its own wireless tag will disrupt the positioning judgment logic during the opening - field positioning process, so it needs to be silenced first) and detects the surrounding environment. When the surrounding environment meets the wireless signal field opening conditions, then turn on the wireless signal field.

[0047] Scan the nearby wireless tags by customizing the verification initial value and default scanning parameters. The purpose of using the custom verification initial value is to distinguish between standard wireless tags and positioning wireless tags in the supermarket. Standard wireless tags refer to other wireless tags in the supermarket except for the positioning wireless tags. Standard wireless tags will have verification errors due to incompatibility with the custom verification initial value and thus will not respond to the scan; positioning wireless tags will be verified correctly due to adaptation to the custom verification initial value and thus will respond to the scan. Similarly, positioning wireless tags will not respond to the scan of standard wireless tags due to cyclic redundancy check errors, that is, using the custom verification initial value can avoid mutual influence during reading. Determine the wireless tags that respond to the scan as positioning wireless tags, silence the positioning wireless tags (that is, silence one wireless tag every time a wireless tag is found to avoid affecting the search for subsequent positioning wireless tags) and record the tag information of the positioning wireless tags.

[0048] Determine whether the number of positioning wireless tags found by scanning meets the positioning requirements. If it meets, stop scanning and release its own wireless tag. If it does not meet, return to execute scanning the nearby wireless tags according to the custom verification initial value until the number of the positioning wireless tags meets the analysis requirements. That is, scan repeatedly multiple times until the number of positioning wireless tags found meets the positioning requirements.

[0049] Based on the above embodiments, optionally, the obtaining the tag information of the nearby positioning wireless tags further includes:

[0050] If the number of the positioning wireless tags still does not meet the positioning requirements after at least two scans, upgrade the field power of the wireless signal field and / or update the scanning parameters, and return to execute scanning the nearby wireless tags according to the custom verification initial value until the number of the positioning wireless tags meets the analysis requirements.

[0051] Specifically, preset the upper limit of the number of scans. For example, set the maximum number of scans to 5 times. If the number of positioning wireless tags found still does not meet the positioning requirements after the number of scans reaches the upper limit, it means that it is meaningless to continue scanning according to the current field power of the wireless signal field and scanning parameters. At this time, upgrade the field power of the wireless signal field to scan with a greater field power; or update the scanning parameters to re-scan with the next set of scanning parameters and reset the number of scans to 0. Gradually upgrade the field power during the scan to avoid directly starting the operation of the electronic price tag with a high field power and reduce the power consumption of the electronic price tag during the process of scanning and positioning the wireless price tag.

[0052] Based on the above embodiments, optionally, the positioning requirements include scanning at least one positioning wireless tag.

[0053] Specifically, to reduce the power consumption of the electronic price tag during the scanning process and maximize its battery life, the positioning requirement can be set to scan at least one positioning wireless tag. That is, as long as a positioning wireless tag is scanned during the first scan, the second scan will not be performed to minimize the number of scans during the positioning process.

[0054] Based on the above embodiments, optionally, the wireless tag includes an NFC tag, the passive wireless tag includes a passive NFC tag, the positioning wireless tag includes a positioning NFC tag, and the wireless signal field includes an NFC field.

[0055] Specifically, the positioning of the electronic price tag can be achieved through the relatively mature NFC technology. During the preparation process, a passive NFC tag is selected as the wireless positioning tag and placed on the shelf, and the location code of its location is written into its internal storage space. During the positioning process, the electronic price tag with NFC reading and writing capabilities uses the NFC field as the wireless signal field to scan the nearby NFC tags through the NFC field to find the nearby positioning NFC tags and determine the tag information of these positioning NFC tags. Correspondingly, when the power of the wireless signal field needs to be adjusted subsequently, the electronic price tag adjusts the field power of its own NFC field. Of course, it is also possible to choose the mature RAID technology to achieve the positioning of the electronic price tag. In the case where the positioning principle has been fully described in other embodiments, the specific implementation process is already predictable to those skilled in the art and will not be elaborated here.

[0056] Based on the above embodiments, optionally, the activation of the wireless signal field includes:

[0057] Detect the signal strength of the wireless signal field energy in the nearby environment;

[0058] If the signal strength of the wireless signal field energy is less than the preset threshold, activate the wireless signal field;

[0059] If the signal strength of the wireless signal field energy is not less than the preset threshold, return to detect the signal strength of the wireless signal field energy in the environment after a random light sleep time.

[0060] Specifically, before turning on the wireless signal field, the electronic price tag first detects the signal strength of the wireless signal field in the surrounding environment. If the signal strength of the wireless signal field energy is less than the preset threshold, it indicates that the environmental energy is blank at this time. Turning on the wireless signal field for positioning can not only reduce power consumption but also avoid interference from irrelevant signals. If the signal strength of the wireless signal field energy is not less than the preset threshold, it indicates that there are other NFC devices working at this time. Turning on the wireless signal field will cause mutual interference, so the wireless signal field is not turned on, and a random time for light sleep is entered. After the light sleep ends, the process returns to detect the signal strength of the wireless signal field energy in the nearby environment. It should be noted that if the number of light sleep times reaches the preset upper limit and the signal strength of the wireless signal field energy is still not less than the preset threshold, there is no need to wait for the signal strength of the wireless signal field energy to be less than the preset threshold, and the wireless signal field is directly turned on.

[0061] S240. Determine the target positioning wireless tag from the positioning wireless tags according to the tag information.

[0062] S250. Read the position code stored in advance in the target positioning wireless tag and report the position code to the server.

[0063] Based on the above embodiments, optionally, before reporting the position code to the server, it further includes:

[0064] Receiving a position query instruction sent by the server through a wireless access point;

[0065] Among them, the server issues a position query instruction when the binding relationship between the ID of the electronic price tag and the minimum stock keeping unit code of the commodity changes, the synchronization signal of the electronic price tag is lost, the wireless access point accessed by the electronic price tag changes, or the electronic price tag has no heartbeat signal for a long time.

[0066] Specifically, the wireless access point serves as a communication intermediary between the server and the electronic price tag. The electronic price tag sends heartbeat data to the server, such as a cloud server. The server obtains the heartbeat data of the electronic price tag and determines that the electronic price tag is in the warehouse. The server initiates an inquiry about the capabilities of the electronic price tag, asking whether the electronic price tag has the ability to locate itself. The electronic price tag feedbacks that it has this ability. Based on this, the server issues attribute configurations related to this ability to the electronic price tag and determines that the functions of the electronic price tag are normal. The electronic price tag responds to the received attribute configurations, and the initialization work is completed. The server continuously monitors the electronic price tag. When it is found that the binding relationship between the ID of the electronic price tag and the Stock Keeping Unit (SKU) code of the commodity has changed, the synchronization signal of the electronic price tag is lost, the wireless access point accessed by the electronic price tag has changed, or the electronic price tag has no heartbeat signal for a long time, it is determined that the position of the electronic price tag has changed, and a position query instruction is issued to it accordingly. After receiving the position query instruction, the electronic price tag reports the position code obtained by self-positioning to the server.

[0067] The embodiment of the present invention optimizes the search logic for the electronic price tag to find the nearby positioning wireless tag, so as to reduce the power consumption of the electronic price tag during the search process and improve the battery life of the electronic price tag.
