Description

Technical Field

[0001] This invention relates to the field of positioning price tags, specifically to an integrated control method, system, and storage medium for independent control and display of positioning price tags. Background Technology

[0002] In the retail sector, price tags are the core information carrier connecting products and consumers, and their role goes far beyond simple price indication. Traditional paper price tags or early electronic shelf labels (ESL) mainly solved the cumbersome problem of manually changing prices, achieving an initial evolution from manual labeling to digital display. However, as the retail industry develops towards digitalization, experientialization, and precision, existing technological solutions are gradually revealing significant limitations in meeting the needs of modern commerce.

[0003] Existing technologies typically focus on solving the efficiency and accuracy issues of price updates. A common implementation involves a central server sending price figures in batches to the e-ink displays at retail outlets via wireless networks (such as proprietary 2.4GHz protocols, LoRa, or Bluetooth). While these systems enable centralized remote price modifications, they are essentially still "one-way, static" information transmission tools. The visual presentation of price tags (such as layout, color scheme, and font) is usually pre-defined and uniform, making it impossible to personalize them based on the unique attributes of specific products (such as category, appearance, and brand image).

[0004] Specifically, the shortcomings of existing technologies are mainly reflected in the following aspects:

[0005] Lack of visual intelligence and personalized design capabilities: Traditional electronic price tags have fixed interface templates and monotonous colors. They cannot automatically recognize the visual characteristics of the product itself (especially the main color tone) and generate an interface design that corresponds to it, thus missing important marketing opportunities to enhance product appeal and convey a sense of quality through color psychology and visual harmony.

[0006] Rigid content updates and weak marketing synergy: The system primarily drives changes to "price figures," making it difficult to dynamically and automatically integrate rich marketing content (such as limited-time tags, selling point icons, and traceability QR codes). The linkage between price changes and the overall interface style requires manual intervention and cannot respond to high-frequency and complex promotional rules (such as dynamic pricing based on inventory and time periods), resulting in slow marketing campaign launches and a fragmented user experience on the terminal.

[0007] Fragmented systems lead to high management costs: Product information management, marketing campaign planning, and price tag equipment management are often handled by different systems, resulting in poor data flow. For a single promotion, operations staff may need to set prices in the ERP system, create materials on the marketing platform, and then manually configure the price tag management system. This process is lengthy, error-prone, and fails to achieve end-to-end automation from "strategy conception" to "terminal presentation."

[0008] Lack of data feedback and closed-loop optimization: Existing systems are mostly "open-loop" controls, only issuing instructions and unable to quantify the actual impact of different price tag designs on sales conversion. The lack of A / B testing and performance analysis capabilities based on real sales data makes price tag optimization rely on experience and intuition, making it difficult to achieve continuous and scientific performance improvement.

[0009] Therefore, the market urgently needs a smarter, more integrated, and more marketing-informed price tag control solution. It should not only achieve efficient price synchronization but also understand products, automatically generate attractive personalized interfaces, respond to complex marketing strategies in real time, and form a data-driven optimization loop. This would truly transform electronic price tags from simple "display terminals" into intelligent "marketing touchpoints and decision-making nodes." Summary of the Invention

[0010] The purpose of this invention is to provide an integrated control method, system, and storage medium for independently controlling and displaying price tags, so as to solve the problems mentioned in the background art.

[0011] To achieve the above objectives, the present invention provides the following technical solution: an integrated control method for independently controlling and displaying positioning price tags, comprising the following steps:

[0012] S1. Product Information Digitization and Feature Extraction: Create digital profiles containing visual features for physical products, automatically extract the main and secondary colors of the products as key visual features through image analysis, and bind and store them with product identification information;

[0013] S2. Automated generation of price tag interface: Based on the key visual features of the product and its product classification, a color scheme is matched from the preset color matching strategy library, and an interface template is selected in combination with the current marketing status of the product to automatically generate structured price tag interface data that corresponds to the visual features of the product.

[0014] S3. Dynamic Update of Price and Content: In response to changes in marketing rules, the displayed price and promotional content of the product are recalculated, and the structured price tag interface data is incrementally updated to generate an update data package;

[0015] S4. Command issuance and terminal synchronization: The update data packet is sent to the target electronic shelf label through the edge computing gateway. The edge computing gateway manages the local shelf label network and drives the specified electronic shelf label to refresh and display.

[0016] Preferably, the image analysis includes image segmentation of the main product image to extract the main product area, and cluster analysis of the pixels in the main product area in the HSL or HSV color space to identify and output at least one representative color value and color attribute label.

[0017] Preferably, the method for matching color schemes from a preset color scheme strategy library includes the following steps:

[0018] Use product category as the index to query the color scheme strategy library and obtain basic color scheme rules;

[0019] Using the primary color in the key visual features as the base color, color calculations are performed according to the basic color matching rules to generate a complete color scheme that includes the background color and accent color.

[0020] Choose either the standard display template or the promotional display template based on whether there are currently any active promotional rules for the product.

[0021] The product information, the color scheme, and the selected template are integrated and rendered to generate a structured interface description file for electronic price tag parsing and drawing.

[0022] Preferably, the marketing rules support complex condition rule configuration based on time and inventory status. When a rule is triggered, the elements related to price and promotional tags in the structured price tag interface data are partially redrawn to generate an incremental update package.

[0023] Preferably, when the update data packet is sent to the target electronic shelf label through the edge computing gateway, the task is scheduled according to the update priority and the store's business status. After the electronic shelf label is refreshed, it returns a confirmation signal to the edge computing gateway.

[0024] Preferably, the structured price tag interface data is a JSON format file, which defines the content, position, color, and style attributes of each displayed element on the price tag screen; the electronic price tag uses an e-ink screen and is parsed and partially refreshed based on the structured price tag interface data.

[0025] Preferably, the color matching strategy library stores preset color matching rules according to product categories. The rules include at least one of adjacent color harmony, complementary color prominence, and neutral color contrast, and are associated with color calculation parameters and applicable scenario descriptions.

[0026] As an option, it also includes monitoring and strategy optimization steps: the edge computing gateway collects the device status and update confirmation receipts of each electronic price tag and reports them to the cloud to form a visual device health dashboard;

[0027] The strategy optimization includes configuring at least two different color schemes for the same type of product and controlling their display on different electronic price tags, and collecting and associating product sales data under different color schemes;

[0028] Based on the correlation analysis results, the impact of each color scheme on sales indicators is evaluated, and the color scheme with better performance is updated to the preset color scheme strategy.

[0029] To solve the above-mentioned technical problems, the present invention also provides an integrated control system for independently controlling and displaying price tags, comprising:

[0030] Memory, used to store computer programs;

[0031] A processor for executing the computer program, which, when executed by the processor, implements the steps of an integrated control method for independently controlling the display of a positioning price tag as described in any of the preceding claims.

[0032] To address the aforementioned technical problems, the present invention also provides a readable storage medium having a computer program stored thereon.

[0033] When the computer program is executed by the processor, it implements the steps of an integrated control method for independently controlling the display of a positioning price tag as described in any of the above-mentioned methods.

[0034] In summary, the beneficial effects of this invention are:

[0035] This invention automatically extracts the main color of a product and intelligently generates a corresponding price tag color scheme. The system upgrades traditional price tags into a visual extension and atmosphere amplifier for the product, effectively improving the harmony and attractiveness of the display, thereby subtly enhancing customers' purchasing inclinations. Simultaneously, its cloud-based centralized management, precise edge distribution, and instant terminal refresh architecture ensures that massive amounts of price tag content can be updated consistently and accurately within milliseconds across a global store network, enabling the reliable and efficient implementation of refined marketing strategies such as dynamic pricing and lightning-fast promotions.

[0036] The present invention also provides an integrated control system and storage medium for independently controlling and displaying positioning price tags, which has the above-mentioned beneficial effects, and will not be elaborated further here. Attached Figure Description

[0041] The present invention will now be described in further detail with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0042] To facilitate understanding of the present invention, a more complete description of the invention will be given below with reference to the accompanying drawings, which illustrate several embodiments of the invention. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the invention will be more thorough and complete.

[0043] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0044] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0045] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of at least two elements or the interaction relationship of at least two elements, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0046] The following is combined Figure 1-3This invention provides a detailed description of one embodiment: an integrated control method for independently controlling and displaying price tags, which can automatically generate electronic price tag interfaces that correspond to the visual characteristics of the product, and realize remote centralized management, real-time synchronization, and dynamic updates of prices and marketing content, ultimately improving product attractiveness and purchase conversion rates. The specific method includes the following steps:

[0047] Step 1: Product Information Input and Feature Binding

[0048] Create a digital profile for each physical product, rich in identifiable features;

[0049] Dual channels for information entry:

[0050] Active data entry: Merchants manually fill in basic product information through the cloud platform's backend management interface and are required or advised to upload high-resolution front-facing main images that meet the specifications. The system will verify the image quality (such as resolution and background clarity).

[0051] Automatic synchronization: A more common scenario is that the system's "product information synchronization module" establishes a connection with the enterprise's central product database (ERP). When a new SKU is created in the ERP, a data package containing its main image link is automatically pushed to this system, achieving "zero-latency" creation of product profiles.

[0052] Intelligent color extraction:

[0053] Image preprocessing: It first uses image segmentation techniques (such as semantic segmentation) to separate the main product from common white or contextual backgrounds, eliminate interference from solid color backgrounds, watermarks, etc., and ensure that color analysis focuses on the product itself.

[0054] Color clustering analysis: Clustering algorithm analysis is performed on the pixels of the main product area in the HSL / HSV color space. 1-3 most representative colors are identified, and the main color (with the largest proportion) and auxiliary colors (embellishment colors or highlight colors) are distinguished, and their center color values ​​are output (such as Hex #FF6B6B).

[0055] At the same time, the system will determine the attributes of the color (such as "high saturation warm color") and assign it implicit labels such as "vibrant" and "eye-catching".

[0056] The extracted color values ​​and color tags are strongly bound to the product SKU and stored in the database as key feature attributes.

[0057] Step 2: Automated generation of price tag interface:

[0058] Once the operations staff completes the product-store-specific shelf allocation within the system, the system considers the product ready for sale and automatically triggers the interface generation request. This is an event-driven process.

[0059] Intelligent color matching decision chain:

[0060] Input: The input received is the product SKU, through which the "extract color" and "product category" stored in step one can be obtained.

[0061] Strategy matching: Use "product category" as the first search key to query the "color scheme strategy library".

[0062] For example, "chocolate" belongs to the "snack food" category, and the default strategy for this category might be "to use a warm background of the same color scheme to create a warm and sweet feeling".

[0063] Color calculation: Based on the product's "extracted color" (such as the brown of chocolate), color calculation is performed according to the matching strategy.

[0064] If the strategy is "adjacent color harmony", then the adjacent colors on the color wheel will be calculated as the background color;

[0065] If the strategy is "complementary color highlighting", then the complementary color will be calculated for key elements such as "promotional price" or "buy button", and sufficient contrast will be ensured during the calculation to meet readability standards.

[0066] At the same time, it will check if there are any currently active promotional rules for the product. If not, the "standard template" (highlighting the brand and product name) will be selected.

[0067] If a major promotion is underway, the "Promotion Explosion Template" will be automatically selected (which includes a large price display area and an eye-catching corner label area).

[0068] The final interface generation is a filling and rendering process. The engine combines the product text information, the calculated color scheme, and the selected template structure to generate a lightweight structured data file (such as JSON format).

[0069] This document defines in detail the position, content, font size, and color value of each block on the price tag screen. It is not an image in itself, but a "blueprint" that can be parsed and drawn by the terminal e-ink screen device.

[0070] Step 3: Dynamic updates to pricing and content

[0071] Rule configuration and activation: In the "Marketing Rule Engine", operators can create promotional activities just like setting calendar reminders. The engine supports complex combinations of conditions, such as "when the inventory is higher than 100 units, apply 'second item half price' to product A; when the inventory is lower than 30 units, automatically switch to 'clearance sale with a discount of XX yuan'".

[0072] Scheduled trigger: The rule engine is triggered when the system time reaches the preset start time of the activity.

[0073] Calculation and Notification: The engine recalculates the latest selling price and promotional text to be displayed for all target products according to the rules, and immediately sends an event notification to the "Intelligent Interface Generation Engine" with the content: "SKU XXX, New Price: YYY, Promotional Tag: Limited Time Discount".

[0074] Incremental Generation: The intelligent interface generation engine eliminates the need to decide on color schemes and templates from scratch. It quickly redraws only the price values, promotional labels, and related color-emphasized areas based on the product's existing "design drafts."

[0075] For example, the original price area can be changed to gray and a strikethrough added, while the new promotional price can be highlighted using the previously calculated "accuracy color." This ensures design consistency while greatly improving update efficiency.

[0076] Data package encapsulation: After re-rendering, generate an "incremental update package" containing only the changed parts or a complete new interface data package, ready for distribution.

[0077] Step 4: Command Issuance and Synchronous Display

[0078] After receiving the update command and data packet, it will break down the large task into smaller tasks based on the physical store where the target product is located.

[0079] The scheduler takes into account factors such as the store's time zone, business hours, and network load. For non-urgent daily price adjustments, it may choose to silently update in batches during the early morning hours after the store closes; for flash sales that take effect immediately, they are immediately added to a high-priority queue and issued in real time.

[0080] The update command is sent to the "edge computing gateway" of the target store through an internet security tunnel.

[0081] The edge gateway acts as the local commander, storing a "shelf-price tag" mapping table for the store. It uses a low-power wireless LAN (such as Bluetooth 5.0 or a dedicated RF interface) to precisely send update data packets to the individual addresses of target electronic price tags, much like a walkie-talkie calling a specific team member. This local communication avoids the latency and instability of the internet.

[0082] After receiving the instruction, the electronic shelf label's internal controller parses the data packet and drives the e-ink screen to refresh only the area where the content has changed (partial refresh), completing the visual update within 1-2 seconds and sending back a "update successful" signal. The entire process, from the operator clicking "take effect" to the shelf label refresh across all stores, can be completed within minutes.

[0083] Step 5: Monitoring and Optimizing the Closed Loop

[0084] Status monitoring and reporting: The edge gateway not only issues commands but also continuously collects heartbeat signals and update confirmation receipts from each price tag, and summarizes and reports them to the cloud. The cloud platform provides a visual "Store Equipment Health Dashboard," with green, yellow, and red icons representing online, low battery, and offline faults, respectively, making maintenance clear at a glance.

[0085] Manual verification and intervention: The system generates an execution report (success / failure list) for each batch update. Operations personnel can use the report to conduct random verification during store visits or through store cameras to ensure that "what you see is what you set up".

[0086] Additionally, in one embodiment, data-driven policy optimization is also included:

[0087] Experiment setup: On the cloud platform, operators can launch an A / B test for a certain type of product (such as coffee). The system will automatically generate two different color schemes for this type of product (such as Group A: coffee brown with beige; Group B: dark blue with gold) and randomly deploy them on the same product price tags in different stores or different regions.

[0088] Data correlation: During the test, the system performed correlation analysis between sales data (POS) and price tag version number.

[0089] Results Analysis: After the test, the system provides an analysis report showing the difference in the improvement effects of Plan A and Plan B on core indicators such as "sales revenue" and "conversion rate".

[0090] Strategy Library Iteration: Operators can solidify the winning color scheme into a new rule (e.g., "For 'specialty coffee' products, a dark blue and gold scheme is recommended") and enter it into the "Color Scheme Library." From this point on, the system completes an autonomous evolution of its design wisdom through data validation.

[0091] It achieves complete lifecycle management from product digitization, intelligent design, dynamic response, precise deployment to continuous optimization, completely transforming electronic shelf labels from a display tool into a smart retail marketing terminal.
