[0005] For electronic price tags (ESTs) powered by micro-energy sources like light or conventional ESTs, the energy source for screen display changes and wireless communications is typically electrical energy converted from light or residual energy, or partially derived from internal backup batteries.

[0047] ESL: Electronic Shelf Label

[0048] LDR: Light Dependent Resistor

[0049] AP: ESL controller (Wireless Access Point)

[0056] SoC: System on Chip.

[0057] Currently, solar-powered or other low-energy electronic price tags derive their energy from converted or residual electricity, with some energy coming from internal backup batteries. Due to the instability of low-energy sources like ambient light and fluctuations in the frequency of price tag operations, the amount of energy converted or stored by the electronic price tags varies dynamically. To ensure the proper functioning of these electronic price tags, monitoring and managing their power consumption is crucial, especially for large-scale deployments of low-energy electronic price tag clusters. Power management and maintenance for these large-scale deployments is a daunting task.

[0058] While some demonstration samples of existing solar-powered electronic price tags exist, they have yet to enter mass production. These demonstration price tags draw their energy from solar cells, which, combined with energy storage devices and power management circuits in the back-end circuitry, enable energy collection, power management, and power monitoring for each individual solar-powered price tag. Each solar-powered electronic price tag's power supply is independently maintained. Consequently, existing solar-powered electronic price tags rely on independent management of the light environment, power management, power monitoring, and power maintenance after light energy is harvested, with manual maintenance required for low-power solar-powered price tags. These tags have yet to achieve intelligent linkage with intelligent devices such as the electronic price tag's back-end IoT management system, intelligent light source equipment, and AI robotics, resulting in high maintenance costs and poor real-time performance.

[0059] Furthermore, existing electronic price tags rely on primary lithium-manganese button batteries, primary lithium-manganese soft-pack batteries, and primary lithium-gerdium sulfonyl chloride batteries. These batteries have limited lifespans and are susceptible to self-discharge. This is also affected by factors such as capacity consumption during standby mode, which limits the battery lifespan of electronic price tags. When the battery is depleted, it must be promptly replaced; otherwise, the electronic price tag will not function properly. This battery replacement method incurs additional labor and cost for the user.

[0060] To address the above issues, the present invention provides an electronic price tag power management system to improve the accuracy and efficiency of electronic price tag power management, extend the life cycle of electronic price tags, and reduce the maintenance cost of electronic price tags. Referring to FIG14 , the system may include:

[0061] Multiple electronic price tags 1401 are used to display the content of the electronic price tags and charge themselves by collecting and converting light energy and other energy sources; collect and report their own electronic price tag status information; the electronic price tag status information includes: remaining battery information, ambient light intensity information, and positioning information; other energy sources include: vibration micro energy, radio micro energy, temperature difference micro energy, and battery energy, or any combination thereof;

[0062] The electronic price tag base station 1402 is configured to forward electronic price tag status information received from multiple electronic price tags based on a preset communication protocol;

[0063] The electronic price tag management device 1403 is used to send a power maintenance instruction to the electronic price tag power maintenance device based on the electronic price tag status information received from the electronic price tag base station and different electronic price tag power management strategies to perform power maintenance on different electronic price tags;

[0064] The electronic price tag power maintenance device 1404 is used to charge the electronic price tag according to the electronic price tag power management strategy and electronic price tag status information carried by the power maintenance instruction, based on different charging methods corresponding to the electronic price tag power management strategy; the charging methods include irradiating the electronic price tag with a light source, transmitting radio energy, and near-field coupling charging.

[0065] In this embodiment, communication between multiple electronic price tags 1401 can be achieved through wireless communication technologies such as Bluetooth and Wi-Fi. Sensors within the electronic price tags 1401 can monitor environmental changes in real time, such as light intensity and temperature, and adjust the charging rate and balance charging status based on the monitoring results. The electronic price tags 1401 can also optimize their charging strategies by collecting and processing information from other sensors, such as humidity and light intensity.

[0066] The electronic price tag management device 1403 can remotely control and manage electronic price tags based on their status information. For example, when the remaining battery power of a particular electronic price tag falls below a preset threshold, the electronic price tag management device 1403 can issue a command to prioritize battery power for that electronic price tag to ensure proper operation. Furthermore, the electronic price tag management device 1403 can also rationally schedule charging times and methods based on the electronic price tag's location information to improve charging efficiency.

[0067] The electronic price tag power maintenance device 1404 can select an appropriate charging method based on the electronic price tag's charging needs and environmental conditions. When charging by irradiating the electronic price tag with a light source, the electronic price tag power maintenance device 1404 can control the angle and light intensity of the electronic price tag 1401 to maximize the light energy conversion efficiency. When charging by transmitting radio energy, the electronic price tag power maintenance device 1404 can adjust the radio transmission power and frequency to improve charging efficiency. When charging by near-field coupling charging, the electronic price tag power maintenance device 1404 can control the charging distance and coupling coefficient of the electronic price tag 1401 to achieve safe and efficient charging.

[0068] In addition, the electronic price tag management system may also include a data storage device 1405 for storing electronic price tag status information and charging history data. The data storage device 1405 can use cloud storage or local storage to ensure secure data storage and convenient query. Managers can view the charging status and historical data of electronic price tags through the electronic price tag management device 1403 to better manage and maintain the electronic price tags.

[0069] The electronic price tag power management system provided in the embodiment of the present application collects and processes the status information of the electronic price tag in real time, and performs targeted power maintenance on the electronic price tag according to different electronic price tag power management strategies, thereby improving the accuracy and efficiency of the power management of the electronic price tag. At the same time, the system adopts a variety of charging methods, making full use of the light energy, vibration micro-energy, radio micro-energy and temperature difference micro-energy in the environment, effectively extending the service life of the electronic price tag and reducing the maintenance cost of the electronic price tag. In short, the electronic price tag power management system provided in the embodiment of the present application has high practicality and broad application prospects.

[0070] In an embodiment of the present application, multiple electronic price tags are configured to display content on the electronic price tags and charge themselves by collecting and converting light energy and other energy sources; collect and report their own electronic price tag status information; the electronic price tag status information includes: remaining battery power information, ambient light intensity information, and positioning information; the other energy sources include: one or any combination of vibration micro-energy, radio frequency micro-energy, temperature difference micro-energy, and battery energy; an electronic price tag base station is configured to forward the electronic price tag status information received from the multiple electronic price tags based on a preset communication protocol; an electronic price tag management device is configured to, based on the electronic price tag status information received from the electronic price tag base station and based on different electronic price tag power management strategies, issue power maintenance instructions to an electronic price tag power maintenance device to perform power maintenance on different electronic price tags; the electronic price tag power maintenance device is configured to charge the electronic price tags based on different charging methods corresponding to the electronic price tag power management strategies and the electronic price tag status information carried in the power maintenance instructions; the charging methods include irradiating the electronic price tags with a light source, transmitting radio energy, and charging by near-field coupling. Compared with the technical solutions in the prior art that can only manage the power consumption of electronic price tags through manual maintenance, the technical solutions proposed in the embodiments of the present application are based on the establishment of electronic price tags that are mainly based on light energy and can support other micro-energy collection, and are combined with electronic price tag management devices to realize the power management and maintenance of electronic price tags in multiple ways using different electronic price tag power maintenance devices, thereby avoiding the current problem of errors and omissions caused by manual maintenance of the power consumption of electronic price tags, and improving the accuracy and management efficiency of the power management of electronic price tags. At the same time, according to the pre-made electronic price tag power management strategy, different charging methods corresponding to the electronic price tag power management strategy can be realized, and intelligent lighting and patrol charging maintenance of electronic price tags can be achieved, achieving the effect of intelligent monitoring, management and maintenance of energy throughout the life cycle of electronic price tags, and also extending the life cycle of electronic price tags, reducing the maintenance cost of electronic price tags.

[0071] During specific implementation, multiple electronic price tags are used to display the content of the electronic price tags and charge themselves by collecting and converting light energy and other energy sources; collect and report their own electronic price tag status information; the electronic price tag status information includes: remaining power information, ambient light intensity information and positioning information; other sources of energy include: vibration micro-energy, radio micro-energy, temperature difference micro-energy and battery energy, one or any combination.

[0072] In practical applications, electronic price tags can achieve more intelligent functions through multiple sensors. These sensors can monitor environmental changes such as temperature, humidity, and light, thereby adjusting the electronic price tag's display content accordingly. In addition, electronic price tags can be connected to other smart devices to achieve data exchange and information synchronization, improving the overall system's collaborative efficiency.

[0073] Energy harvesting technology can convert ambient micro-energy, such as vibration, radio frequency, and temperature difference, into electrical energy, providing a continuous and stable power source for electronic price tags. This self-sufficient charging method not only reduces operating costs but also offers environmental and energy-saving advantages.

[0074] To ensure stable operation of electronic price tags, the system also needs to have fault detection and self-repair capabilities. When a fault is detected, the system automatically issues an alarm and promptly uploads the fault information. By analyzing this information, maintenance personnel can quickly locate the problem and take appropriate measures to repair it. Furthermore, the electronic price tag can automatically adjust its operating parameters based on its own status and environmental changes to ensure optimal display quality and battery life.

[0075] In terms of management, ESLs can be centrally managed through a cloud computing platform. This platform receives real-time status information uploaded by ESLs, such as remaining battery life and location information, and uses this information for data analysis and decision-making. Through this cloud computing platform, merchants can better understand product sales and make adjustments based on demand.

[0076] In this embodiment, communication between the multiple electronic price tags 1401 uses wireless communication technology, such as Bluetooth, Wi-Fi, or other wireless communication protocols. The electronic price tags 1401 can also collect environmental information, such as temperature, humidity, and light, through sensors and upload this information to the electronic price tag base station 1402.

[0077] In the embodiment, one or more of solar cells and energy collection and conversion circuits, light intensity detection circuits, near-field coupling circuits such as NFC, radio energy collection circuits, backup batteries, etc. are integrated into the existing electronic price tags, so that the energy source of the electronic price tags is mainly light energy, while supporting other energy sources such as micro energy collection and backup batteries.

[0078] In one embodiment, the electronic price tag includes: a control module, a positioning module, an ambient light intensity monitoring module, an energy storage device, a micro-energy charging circuit, a communication module, and a solar cell.

[0079] The positioning module is used to determine the positioning information of the electronic price tag.

[0080] The ambient light intensity monitoring module is used to monitor the ambient light intensity of the electronic price tag.

[0081] Solar cells are used to charge energy storage devices by collecting and converting light energy; light energy includes ambient light and sunlight.

[0082] The micro-energy charging circuit is used to charge the energy storage device by collecting and converting vibration micro-energy, radio micro-energy and temperature difference micro-energy.

[0083] The control module is used to determine the remaining power information of the electronic price tag based on the collected power-related parameters inside the electronic price tag.

[0084] The communication module is used to report the remaining power information, ambient light intensity information and positioning information of the electronic price tag.

[0085] In the above embodiment, the electronic price tag also features an ambient light intensity monitoring module, which monitors and reports ambient light intensity. Based on this light intensity information, the electronic price tag's power maintenance device adjusts the intelligent light source surrounding the price tag to recharge the price tag. Unlike LCD price tags, EPD (electronic paper display) electronic price tags are non-luminous. Furthermore, the electronic price tag is equipped with a wireless charging circuit that receives wireless charging energy from a charging base via radio waves to provide power to the electronic price tag.

[0086] Electronic price tags (ESTs) are widely used in retail locations, including but not limited to supermarkets, shopping malls, and pharmacies. In these locations, ESTs can display product prices in real time, making them convenient for consumers to view. Furthermore, through communication modules, ESTs can interact with backend management systems, enabling various functions such as inventory management and price adjustments.

[0087] To ensure the stable operation of the electronic price tag, the system is also equipped with a power management circuit for intelligently managing the internal battery of the electronic price tag. The power management circuit can rationally allocate the battery's energy output based on the electronic price tag's real-time power demand, thereby extending the electronic price tag's service life. In addition, the electronic price tag is equipped with a micro-energy charging circuit, which collects and converts micro-energy such as vibration, radio frequency, and temperature differences to provide additional protection for the electronic price tag's battery life.

[0088] In terms of positioning modules, electronic price tags can use various positioning technologies such as GPS, Bluetooth, Wi-Fi, and electronic price tag proprietary protocols to accurately obtain the location information of electronic price tags. This location information can be used to implement functions such as product traceability and logistics tracking, providing more convenience for businesses and consumers.

[0089] In this embodiment, smart devices can maintain the lighting environment and power consumption of solar-powered price tags, extending their lifespan and effectively reducing their carbon footprint, in line with the current trend of low-carbon and environmentally friendly IoT products. Furthermore, smart devices can significantly reduce manual maintenance hours and lifetime costs during the lifespan of solar-powered price tags by maintaining the lighting environment and power consumption of these tags.

[0090] In one embodiment, the control module is specifically configured to:

[0091] When the electronic price tag is in working state, the remaining power information of the electronic price tag is determined based on the load voltage parameter of the energy storage module of the electronic price tag and the association relationship between the preset load voltage parameter and the remaining power information;

[0092] When the electronic price tag is in a non-working state, the remaining power information of the electronic price tag is determined based on the open circuit voltage parameter of the energy storage module of the electronic price tag and the association relationship between the preset open circuit voltage parameter and the remaining power information;

[0093] and / or determining the remaining power information of the electronic price tag based on a voltage difference between an open-circuit voltage parameter and a load voltage parameter of the energy storage module of the electronic price tag and a preset correlation relationship between the voltage difference and the remaining power information;

[0094] And / or, integrating the current consumption generated by the electronic price tag executing the instruction operation to obtain the power consumption generated by the electronic price tag executing the instruction operation; and determining the remaining power information of the electronic price tag based on the power consumption.

[0095] Specifically, various methods can be used to accurately determine the remaining power information of the electronic price tag, including:

[0096] First, while the electronic price tag is in operation, the control module monitors the load voltage parameters of the electronic price tag's energy storage module. By comparing the preset load voltage parameters with the actual measured values, the remaining power of the electronic price tag can be calculated. This method can provide real-time information on the electronic price tag's power consumption while it is in operation.

[0097] Secondly, when the electronic price tag is not in operation, the control module detects the open-circuit voltage parameter of the electronic price tag's energy storage module. Based on the relationship between the preset open-circuit voltage parameter and the remaining power information, the remaining power of the electronic price tag can be estimated. This method can effectively predict the remaining power of the electronic price tag when it is in the non-operating state.

[0098] Next, the control module can determine the remaining charge of the electronic tag by analyzing the voltage difference between the open-circuit voltage parameter and the load voltage parameter of the electronic tag energy storage module. This method comprehensively considers the voltage and current characteristics of the electronic tag and can more accurately predict the remaining charge of the electronic tag.

[0099] Finally, the control module can also integrate the current consumption generated by the electronic price tag executing the command operation to obtain the power consumption generated by the electronic price tag executing the command operation. Based on this power consumption, the remaining power information of the electronic price tag can be further determined. This method can accurately calculate the power consumption of the electronic price tag during each command operation, providing a more accurate basis for estimating the remaining power.

[0100] In a specific implementation case, the implementation methods for reporting the power information of the solar electronic price tag mainly include the following, as shown in Figure 3:

[0101] 1. The load voltage parameter of the energy storage device represents the remaining power:

[0102] The load voltage of the energy storage device measured under typical ESL operating conditions, that is, typical load current, includes but is not limited to the following parameters:

[0103] When the ESL is in the RF receiving or transmitting state, the ESL circuit samples and obtains the output load voltage of the energy storage device;

[0104] When the ESL is in the state of updating the screen display content, the ESL circuit samples the output load voltage of the energy storage device; the following methods are optional;

[0105] When the ESL is in the LED flashing state, the ESL circuit samples the output load voltage of the energy storage device;

[0106] The backend system calculates the remaining capacity of the energy storage device based on the correspondence between the energy storage device type and the load voltage in this characteristic state (such as the load voltage in the RF Burst state in Figure 4) and the capacity of the energy storage device under the preset ESL characteristic state.

[0107] 2. The open circuit voltage parameter of the energy storage device represents the remaining capacity:

[0108] When the ESL is in the sleep standby state, the ESL circuit samples the no-load voltage of the energy storage device (such as the no-load voltage corresponding to the ESL standby low current state in Figure 4) and reports it to the background system;

[0109] The background system calculates the remaining capacity of the energy storage device based on the preset energy storage device type, its open circuit voltage and the corresponding relationship between the energy storage device capacity.

[0110] 3. The voltage difference parameter of the energy storage device represents the remaining power (this is an optional method):

[0111] The ESL collects the voltage difference between the load voltage and the no-load voltage in the RF burst state (such as V1 or V2 in Figure 4) and reports it to the background system;

[0112] The background system calculates the remaining capacity of the energy storage device based on the corresponding relationship between the voltage difference and the capacity of the energy storage device under the preset RF burst characteristic current.

[0113] 4. The integral capacity parameter of the energy storage device current over time represents the remaining capacity:

[0114] As shown in Figure 5, the ESL monitors internal command operations and integrates the current consumption generated by each command operation to obtain the ESL cumulative power consumption Q (mAh) as of the current moment.

[0115] Q=3I1*T1+I2*T2

[0116] Wherein, Q represents the cumulative power consumption of the ESL up to the current moment; I1 represents the typical pulse current of the RF receive frame in the ESL standby state; T1 represents the typical pulse current time width of the RF receive frame in the ESL standby state; I2 represents the typical pulse current of the RF transmit frame in the ESL standby state; T2 represents the typical pulse current time width of the RF transmit frame in the ESL standby state.

[0117] The electronic shelf label backend system or electronic shelf label deducts the power consumption Q from the known energy storage device capacity to obtain the remaining power of the ESL energy storage device.

[0118] 5. Load output voltage or current of power devices such as solar cells;

[0119] In the case that the ESL has no internal energy storage device (such as a large area solar cell), the ESL monitors and collects the load output voltage or current of the power device such as the solar cell and reports it to the background system;

[0120] The electronic price tag backend system or electronic price tag obtains the driving state of the device based on the known driving capability of the output voltage or current of the power device such as the solar cell.

[0121] The above five methods can all be used to report the power information of solar electronic price tags, so as to accurately monitor and evaluate the remaining power of energy storage devices.

[0122] For example, a micro-energy electronic price tag consists of the following components: a light-powered electronic price tag (optional) includes an ESL main control circuit, a light intensity acquisition circuit or module, solar cells, energy storage devices, power management circuits, micro-energy charging circuits, wireless charging circuits, software wireless positioning algorithms, and other components or hardware and software modules. The main functions of each module of the light-powered electronic price tag are as follows:

[0123] The main control circuit is responsible for wireless communication, price change display and wireless positioning of the electronic price tag;

[0124] The light intensity acquisition circuit or module is equipped with a light-sensitive sensor such as LDR to monitor the ambient light intensity;

[0125] The main control circuit collects parameters such as power, voltage, and current inside the price tag to monitor the remaining power;

[0126] The communication module provides various parameters and status information of the electronic price tag to the IOT (Internet of Things) platform of the electronic price tag management system;

[0127] The electronic price tag obtains and reports location information through wireless communication and positioning algorithms;

[0128] The electronic price tag integrates solar cells, and can also integrate micro-energy transducers such as vibration and radio, as well as energy collection circuits, to achieve micro-energy collection;

[0129] Other types of renewable micro-energy electronic price tags integrate micro-energy transducers such as vibration, radio, and temperature difference, as well as energy collection circuits. They also include main control circuits, energy storage devices, power management circuits, wireless positioning algorithms, etc.

[0130] In this embodiment, the operating principle of the micro-energy electronic price tag can be divided into the following steps:

[0131] First, the solar-powered electronic price tag collects ambient light energy through solar cells and converts it into electrical energy. Part of this energy is used for power supply, and the other part is stored in energy storage devices for future use.

[0132] Next, the ESL main control circuit manages the collected energy to ensure the normal operation of the electronic price tag. The light intensity collection circuit or module is responsible for monitoring the ambient light level. The electronic price tag power maintenance device can formulate intelligent maintenance strategies based on the light intensity information reported by the price tag and the remaining power status of the energy storage device to ensure the stable operation of the electronic price tag.

[0133] Furthermore, the electronic price tag also features wireless communication and wireless positioning. The communication module transmits the electronic price tag's various status and parameters to the electronic price tag management system's IoT platform. Through wireless communication and positioning algorithms, the electronic price tag can obtain its own location information and report it to the management system.

[0134] In terms of micro-energy harvesting, electronic price tags integrate not only solar cells but also micro-energy transducers such as vibration and radio energy, as well as energy harvesting circuits. These micro-energy transducers and energy harvesting circuits can collect micro-energy such as vibration and radio energy in the environment, further improving the energy efficiency of electronic price tags.

[0135] Finally, the ESL uploads the collected information to the ESL management system IoT platform through wireless communication and positioning algorithms. This allows managers to understand the ESL's operating status in real time and remotely control and manage it as needed.

[0136] In short, micro-energy electronic price tags fully utilize micro-energy harvesting technology to achieve energy conservation and environmental friendliness. By integrating multiple functional modules, such as light energy harvesting, wireless communication, and wireless positioning, the electronic price tags not only achieve low energy consumption but also provide convenient management methods.

[0137] In a specific implementation, the electronic price tag base station is used to forward the electronic price tag status information received from multiple electronic price tags based on a preset communication protocol.

[0138] The electronic price tag base station acts as an information transfer station, responsible for receiving and processing status information from each electronic price tag. The base station uses a preset communication protocol to ensure the accuracy and timeliness of the information. After receiving the status information sent by the electronic price tag, the base station will analyze and process this information. In the embodiment, the base station mainly receives, processes, and forwards information, and is usually not used as a device for batch processing of important information data. Large quantities of product data information are the work of the backend system, that is, the work of the electronic price tag management device.

[0139] In one implementation case, it is built on the basis of wireless communication protocols such as proprietary protocols / BT / WiFi, and involves components such as ESL monitoring system, ESL management system, map and navigation services and database, including electronic price tags, APs, WiFi routers, database servers and docking servers and other hardware devices. The typical system equipment is shown in Figure 6.

[0140] Typical functions of the price tag system include but are not limited to: binding / unbinding, updating, multi-page storage, frame adjustment, global flashing, global page switching, fast flashing, fast page switching, precise timing services, point-to-point flashing, point-to-point page switching, heartbeat, price tag upgrade, base station upgrade, network optimization, timed screen refresh, temperature collection, equipment and communication security, fast network access, mobile scenarios and positioning (electronic price tags and intelligent maintenance equipment, etc.), etc.

[0141] In the above embodiment, the ESL base station uses advanced algorithms and data analysis technologies to efficiently process the collected ESL status information. The base station houses a highly efficient data processing unit capable of analyzing the status information transmitted by the ESL in real time and rapidly transmitting the results to the relevant merchants or management personnel. Furthermore, the base station also features an artificial intelligence assistant that, by mining and analyzing historical data, predicts product sales trends and provides merchants with more precise marketing strategies.

[0142] The ESL base station also features remote monitoring and maintenance. Merchants or managers can monitor ESL usage through the base station, gaining real-time insights into product sales and inventory. If an abnormality occurs, the base station automatically issues an alarm, alerting relevant personnel to address it promptly. This helps reduce operating costs and improve management efficiency.

[0143] Furthermore, the ESL base station supports multiple communication protocols, including proprietary protocols, Bluetooth, and WiFi, offering excellent compatibility and stability. In practical applications, the base station can seamlessly connect with other system devices, such as access points (APs) and WiFi routers, enabling data exchange and sharing. This provides strong support for building a smart retail ecosystem.

[0144] To achieve more efficient data processing and analysis, the ESL base station can also be integrated with other business systems, such as mapping and navigation services, and databases. For example, product inventory and sales status can be plotted on electronic maps, providing merchants with intuitive business data analysis. Furthermore, the base station can be connected to smart devices, such as smart handheld terminals and smart surveillance cameras, to enable the collection and processing of diverse data.

[0145] In specific implementation, the electronic price tag management device is used to send power maintenance instructions to the electronic price tag power maintenance device based on the electronic price tag status information received from the electronic price tag base station and different electronic price tag power management strategies to perform power maintenance on different electronic price tags.

[0146] After receiving the electronic price tag status information transmitted by the electronic price tag base station, the electronic price tag management device will issue a power maintenance instruction to the electronic price tag power maintenance device according to different electronic price tag power management strategies. This operation performs power maintenance on different electronic price tags, ensuring the normal operation of the electronic price tags.

[0147] During implementation, the ESL management device categorizes and manages ESLs based on their real-time status. For example, for ESLs with insufficient power, the device will prioritize issuing power replenishment instructions to ensure they meet normal operating requirements. Meanwhile, for ESLs with sufficient power, the device will regularly check to ensure their power levels remain within a reasonable range.

[0148] In addition, the ESL management device will adjust the ESL power management strategy based on the ESL's usage scenario and importance. For example, during critical occasions or important time periods, the ESL management device will strengthen the monitoring of the ESL's power consumption to ensure its stable operation. During non-critical occasions or non-important time periods, the ESL management device will appropriately reduce the management of the ESL's power consumption to conserve resources.

[0149] During the ESL power maintenance process, the ESL management device also works in conjunction with other related devices. For example, when the ESL battery is low, the ESL management device communicates with the charging device to provide charging services for the ESL. Furthermore, the ESL management device dynamically adjusts the charging strategy based on the ESL's charging progress to ensure efficient and safe charging of the ESL.

[0150] In summary, power management via the ESTA management device effectively ensures the normal operation of ESTAs. Furthermore, the ESTA management device dynamically adjusts power management strategies based on the ESTA's status and usage scenarios, enabling intelligent management of ESTAs. This will help improve the effectiveness of ESTA applications and reduce maintenance costs.

[0151] In this embodiment, the electronic price tag management device 1403 can analyze the status information of the electronic price tag to obtain the remaining power and location information of each electronic price tag in real time. Based on this information, the electronic price tag management device 1403 can formulate corresponding power management strategies for different electronic price tags. These strategies include but are not limited to:

[0152] 1. For electronic price tags with low remaining power, the electronic price tag management device 1403 can prioritize the allocation of energy collection and charging resources to ensure their normal operation.

[0153] 2. For electronic price tags in remote locations, the electronic price tag management device 1403 can adjust the charging method and frequency of the electronic price tags to reduce energy loss.

[0154] 3. For an electronic price tag that has not been used for a long time, the electronic price tag management device 1403 can put the electronic price tag into a sleep mode to reduce energy consumption.

[0155] In one embodiment, the electronic price label management device is specifically used to:

[0156] Determine the power status, ambient light intensity information, and positioning information of each electronic price tag based on the electronic price tag status information received from the electronic price tag base station;

[0157] Determine the charging priority of different electronic shelf tags based on the power status of each electronic shelf tag;

[0158] Based on artificial intelligence technology, the charging topology of each electronic price tag is determined according to its charging priority, ambient light intensity, and positioning information. The charging topology is used to display the charging sequence of different electronic price tags and the power management strategy of the electronic price tags.

[0159] According to the charging topology of the electronic price tag, a power maintenance instruction is sent to the electronic price tag power maintenance device to perform power maintenance on different electronic price tags.

[0160] Taking a specific example, as shown in Figures 1 and 2, the management platform of the electronic price tag system can be divided into the following levels:

[0161] 1. The basic layer of the electronic price tag application management system: SaaS cloud management platform;

[0162] 2. Support layer of electronic price tag application management system: system API interface;

[0163] 3. The renewable micro-energy electronic price tag power monitoring and maintenance platform mainly includes the following systems:

[0164] 3.1 Electronic price tag power monitoring and maintenance platform;

[0165] 3.2 Solar electronic price tag power monitoring and maintenance system;

[0166] 3.3 Backend system, located in the cloud or local server, mainly includes the following modules:

[0167] 3.3.1 Price tag reporting information extraction module;

[0168] 3.3.2 AI intelligent analysis and decision-making module;

[0169] 3.3.3 Early warning and maintenance instruction interaction module;

[0170] 3.3.4 Shelf and electronic price label location information service system.

[0171] Specifically, the implementation process of the electronic price label management device is as follows:

[0172] First, the ESL management device determines the battery level and location of each ESL based on the ESL status information received from the ESL base station. This step is primarily to obtain real-time ESL status, providing a basis for subsequent charging management.

[0173] Next, the ESL management device determines the charging priority of each ESL based on its battery level. This step aims to ensure fairness and efficiency in charging. The priority can be determined based on factors such as the remaining battery level and the importance of the device.

[0174] Then, powered by artificial intelligence, the ESL management device determines a charging topology for each ESL based on its charging priority and location information. This topology is a graphical representation of the charging sequence and power management strategy for each ESL, helping managers clearly understand the charging process and power management strategy.

[0175] Finally, based on the charging topology of the electronic price tag, the electronic price tag management device will send a power maintenance instruction to the electronic price tag power maintenance device to perform power maintenance on different electronic price tags. The main purpose of this step is to achieve real-time charging management of the electronic price tag and ensure the normal operation of the electronic price tag. Specifically, based on the charging topology of the electronic price tag, the electronic price tag management device will send a power maintenance instruction to the electronic price tag power maintenance device. The power maintenance for different electronic price tags can be that the electronic price tag management device determines the order of sending power maintenance instructions to different electronic price tag power maintenance devices based on the charging sequence of different electronic price tags in the charging topology of the electronic price tag and / or the electronic price tag power management strategy, and then sends a power maintenance instruction to the electronic price tag power maintenance device based on the order, and performs power maintenance on different electronic price tags. Furthermore, the order of issuing power maintenance instructions to different electronic price tag power maintenance devices can be, for example, the charging order of different electronic price tags. For example, it can also be based on the charging order of different electronic price tags and the electronic price tag power management strategy to determine indicator data representing the charging urgency, and determine the order of issuing power maintenance instructions to different electronic price tag power maintenance devices based on the indicator data (for example, the larger the indicator data, the more urgent the need for charging, and the higher the order).

[0176] In summary, the ESL management device achieves intelligent management of ESLs by receiving ESL status information, determining charging priorities, generating charging topology maps, and issuing power maintenance instructions. This management approach not only improves charging efficiency and reduces risks during the charging process, but also provides a convenient ESL user experience. In practical applications, the ESL management device can be widely used in places such as shopping malls and warehouses where real-time product information management is required.

[0177] In specific implementation, the electronic price tag power maintenance device is used to charge the electronic price tag based on the electronic price tag power management strategy and electronic price tag status information carried by the power maintenance instruction, based on different charging methods corresponding to the electronic price tag power management strategy; the charging methods include irradiating the electronic price tag with a light source, transmitting radio energy, and near-field coupling charging.

[0178] During implementation, the ESL power maintenance device first needs to obtain the ESL's power maintenance instructions, which contain the ESL's power management strategy and status information. Based on this information, the ESL power maintenance device will adopt the appropriate charging method to charge the ESL.

[0179] There are three main charging methods: light irradiation charging, radio energy transmission charging, and near-field coupling charging. These three charging methods each have their own characteristics and can meet the charging needs of electronic price tags in different scenarios.

[0180] Light-irradiation charging utilizes energy from a light source to charge the electronic shelf tag. This charging method is highly adaptable to various environments and can provide a stable charging source for the electronic shelf tag in any environment with sufficient sunlight. Furthermore, light-irradiation charging is environmentally friendly, as the light source can be natural light, such as sunlight, or artificial light, such as LED lights. This charging method is suitable for both outdoor and well-lit indoor environments.

[0181] Radio energy transmission charging uses radio waves to provide charging energy for electronic price tags. This charging method eliminates the need for physical contact and maintains stable charging even at long distances. Radio energy transmission charging offers high flexibility and convenience, making it suitable for a variety of scenarios. For example, it can be used for wireless charging between smart home devices and for wireless charging of electric vehicles.

[0182] Near-field coupling charging uses a near-field magnetic field to provide charging energy to electronic price tags. This charging method offers the advantages of fast charging speed and high efficiency, and can achieve efficient charging over short distances. Near-field coupling charging is suitable for scenarios requiring high charging speed and efficiency, such as charging automated equipment on production lines and high-speed charging stations.

[0183] In practice, the ESL battery maintenance device flexibly selects the appropriate charging method based on the ESL's actual status and environmental conditions. During the charging process, the device monitors the ESL's charging status in real time to ensure safe and effective charging. Furthermore, through connection to a cloud platform, the ESL battery maintenance device uses artificial intelligence to continuously learn and optimize charging strategies, improving charging efficiency and reducing charging costs.

[0184] In short, the ESL battery maintenance device provides efficient, safe, and environmentally friendly charging services for ESLs through three charging methods: light illumination charging, radio energy transmission charging, and near-field coupling charging. In practical applications, the ESL battery maintenance device can flexibly select the appropriate charging method based on the actual needs of the ESL and environmental conditions, effectively managing the ESL battery level. This helps extend the lifespan of the ESL, reduce operating costs, and provide a convenient, intelligent experience for consumers and businesses.

[0185] In the embodiment, after receiving the power maintenance instruction, the electronic price tag power maintenance device 1404 will charge the electronic price tag using a corresponding charging method according to the actual situation of the electronic price tag. These charging methods include:

[0186] 1. Light source irradiation charging: Use light to illuminate the photocell on the surface of the electronic price tag and convert light energy into electrical energy for charging.

[0187] 2. Radio energy charging: By emitting radio waves, radio energy is converted into electrical energy for charging.

[0188] 3. Near-field coupling charging: Utilize the principle of near-field magnetic resonance to achieve wireless charging between electronic price tags and charging devices.

[0189] In this embodiment, an electronic price tag with multiple energy sources and integrated multiple types of sensors, combined with a background electronic price tag power monitoring and maintenance system that integrates a price tag management system, a price tag positioning and navigation system, and various AI power maintenance devices, can achieve intelligent monitoring, management, and maintenance of energy throughout the entire life cycle of the electronic price tag. It should be noted that this application does not limit the types of charging methods, that is, in addition to the above three charging methods, other charging methods can also be included.

[0190] In one embodiment, the electronic price tag power maintenance device includes an artificial intelligence inspection robot;

[0191] Artificial intelligence inspection robots, including:

[0192] A first electronic price tag positioning module, configured to determine a first electronic price tag to be charged based on positioning information in the electronic price tag status information carried by the power maintenance instruction;

[0193] The first charging module is used to call the charging method corresponding to the electronic price tag power management strategy carried by the power maintenance instruction when the artificial intelligence inspection robot moves to the position of the electronic price tag to be charged, and charge the first electronic price tag to be charged.

[0194] In this embodiment, the core component of the electronic price tag power maintenance device is an artificial intelligence inspection robot. This robot has multiple functional modules, including a first electronic price tag positioning module and a first charging module.

[0195] First, the first ESL positioning module is responsible for accurately locating the first ESL that needs charging based on the ESL status information contained in the power maintenance instruction. This positioning module can use various positioning technologies, such as RFID, Bluetooth, and Wi-Fi, to ensure that the robot can accurately find the ESL that needs charging.

[0196] When the AI ​​inspection robot moves to the location of an ESL to be charged, the first charging module comes into play. Based on the ESL power management strategy contained in the power maintenance instruction, this module invokes the appropriate charging method to charge the first ESL. This charging method can be wireless, wired, or other to meet the needs of different scenarios.

[0197] In addition, the electronic price tag power maintenance device can also be equipped with other functional modules, such as a second electronic price tag positioning module, a second charging module, a data transmission module, etc. These modules can work together to further improve the charging efficiency and stability of the electronic price tag.

[0198] In practical applications, the ESL battery maintenance device can be widely used in shopping malls, supermarkets, warehouses, and other places. Regular inspections and charging by AI inspection robots can ensure that the ESL battery level remains within the appropriate range, thus ensuring the proper functioning of the ESL. Furthermore, this device can be integrated with other intelligent systems, such as product management systems and warehouse management systems, to achieve intelligent and automated charging management.

[0199] In this embodiment, the artificial intelligence inspection robot and its charging method provide an efficient and intelligent solution for maintaining the power level of electronic price tags. In the future, with the continuous advancement of technology, the power maintenance device of electronic price tags will be further improved to provide better services for various scenarios.

[0200] As a specific example, Figure 8 shows the system architecture of an AI inspection robot. The following details the robot's positioning and navigation, power replenishment methods, and key equipment:

[0201] The robot positioning system (for example, the first ESL positioning module is part of the robot positioning system) consists of two parts: the ESL communication positioning system and the robot navigation and positioning subsystem. The ESL communication positioning system includes ESL devices or modules with proprietary protocols, BT, or WiFi communication protocols, and positioning capabilities. The robot navigation and positioning subsystem includes radar-assisted positioning, image-assisted positioning, and inertial navigation.

[0202] The AI ​​inspection robot's recharge method is as follows: the backend server notifies the robot of the shelf location of any ESLs requiring recharge, and the robot navigates accordingly. If a shelf contains one or more ESLs requiring recharge, the robot confirms their location by flashing the ESLs' lights or updating the screen. If the ESLs' battery level is insufficient to flash or update, the robot will take the following recharge measures: uniformly recharging all ESLs on the shelf; individually recharging any ESLs that haven't flashed or updated; or recharging each one individually using methods such as near-field coupling or radio waves. The recharging duration can be adjusted based on the ESL's battery level.

[0203] In the X86 computing subsystem, the robot's core processor module calculates the trajectory path and drives the robot's drive subsystem based on background scheduling instructions, combined with robot positioning information, target price tag location information and map data, to perform maintenance actions.

[0204] The robot's power supply energy output devices or interfaces include: near-field coupling devices or interfaces such as NFC, fill lights such as robot control, and radio wave transmission interfaces.

[0205] In one embodiment, the electronic price tag power maintenance device includes an artificial intelligence shopping cart;

[0206] AI shopping cart, including:

[0207] A second electronic price tag positioning module is configured to determine a second electronic price tag to be charged within a preset range of the artificial intelligence shopping cart based on the positioning information in the electronic price tag status information carried by the power maintenance instruction;

[0208] The second charging module is used to call the charging method corresponding to the electronic price tag power management strategy carried by the power maintenance instruction during the movement of the artificial intelligence shopping cart, and charge all second electronic price tags to be charged within a preset range of the artificial intelligence shopping cart.

[0209] In this embodiment, the core component of the electronic price tag power maintenance device is an artificial intelligence shopping cart. The artificial intelligence shopping cart mainly consists of two parts: a second electronic price tag positioning module and a second charging module.

[0210] The second ESL positioning module is responsible for accurately determining the location of the second ESL to be charged within the preset range of the AI ​​shopping cart based on the ESL status information contained in the power maintenance instruction. The effective operation of this module ensures that the ESL can be charged at the correct location.

[0211] The second charging module is responsible for invoking the appropriate charging method based on the ESL power management strategy contained in the power maintenance instruction during the movement of the AI ​​shopping cart, charging all the second ESLs within the preset range. The operation of the second charging module ensures that the ESLs are charged according to the preset strategy, thereby maximizing the lifespan of the ESLs.

[0212] In addition, the AI ​​shopping cart also has a real-time power monitoring function, which can monitor the power level of the electronic price tag in real time to ensure that the electronic price tag will not be overcharged or undercharged during the charging process. This function further improves the accuracy and safety of the electronic price tag charging.

[0213] In general, the electronic price tag power maintenance device in this embodiment fully utilizes the advantages of the artificial intelligence shopping cart, realizes the precise positioning and efficient charging of the electronic price tag, and effectively improves the use efficiency and life of the electronic price tag.

[0214] For example, the system architecture of an AI shopping cart is shown in Figure 9. The modules related to positioning and price tag charging equipment are as follows:

[0215] 1. The AI ​​shopping cart positioning method (for example, the positioning method of the second electronic shelf label positioning module) consists of two parts:

[0217] Positioning subsystem: This subsystem consists of two parts: radar-assisted positioning and inertial positioning.

[0218] 2. Shopping Cart Master Control System: This system includes a core processor and control module. Based on backend dispatch instructions, the master control system maintains the power levels of neighboring price tags around the shopping cart based on the cart's location information, neighboring price tag locations, and map data.

[0219] 3. Shopping cart power-replenishing energy output devices or interfaces: including near-field coupling devices or interfaces such as NFC, fill lights for robot control, radio wave transmission interfaces, etc.

[0220] In short, the AI ​​shopping cart system realizes functions such as intelligent positioning of the shopping cart and price tag charging through the collaborative work of various modules.

[0221] In one embodiment, the electronic price tag power maintenance device includes an artificial intelligence light source;

[0222] Artificial intelligence light source, including:

[0223] a third electronic price tag positioning module, configured to determine a third electronic price tag to be charged within the radiation range of the artificial intelligence light source based on the positioning information in the electronic price tag status information carried by the power maintenance instruction;

[0224] The third charging module is used to call the charging method corresponding to the electronic price tag power management strategy carried by the power maintenance instruction, and charge the third electronic price tag to be charged within the radiation range of the artificial intelligence light source.

[0225] In this embodiment, the core component of the electronic price tag power maintenance device is the artificial intelligence light source. The artificial intelligence light source mainly consists of two parts: the third electronic price tag positioning module and the third charging module.

[0226] The third ESL positioning module is responsible for accurately locating the third ESL to be charged within the radiation range of the AI ​​light source based on the ESL status information contained in the power maintenance instruction. This positioning module can utilize various positioning technologies, such as RFID, Bluetooth, and Wi-Fi, to obtain the ESL's location information. This ensures that the charging light source accurately charges the ESL in need, avoiding resource waste and charging errors.

[0227] The third charging module is responsible for selecting an appropriate charging method for the third ESL to be charged, based on the ESL power management strategy contained in the power maintenance instruction. This charging module is compatible with multiple charging methods, such as wireless charging and USB charging, to meet the charging needs of different ESL types. Furthermore, the charging module intelligently adjusts the charging power and charging time based on the ESL's real-time power status and charging needs to achieve optimal charging results.

[0228] The entire electronic price tag power maintenance device operates as follows: first, it receives a power maintenance instruction, which contains the electronic price tag's status information and power management strategy; then, the third electronic price tag positioning module determines the location of the electronic price tag to be charged; then, according to the power management strategy, the electronic price tag is charged through the third charging module; finally, the charging process is monitored to ensure charging safety and charging effect.

[0229] In this way, the ESL power maintenance device can achieve intelligent management and charging of a large number of ESLs, significantly improving charging efficiency and reducing operating costs. Furthermore, by combining big data and machine learning technologies, it can analyze and predict charging behavior, further optimizing charging strategies and improving the utilization rate and service quality of charging equipment.

[0230] Taking a specific example, the implementation of the AI ​​light source is shown in Figure 7, but is not limited to the form of Figure 7. Based on private protocols, Bluetooth (BT), wireless local area network (WiFi) and other electronic tag system wireless communication protocols, the monitoring of the AI ​​light source equipment is realized; the AI ​​light source equipment is based on the electronic tag circuit, retains modules such as radio frequency (RF), near-field communication (NFC), embedded system-level chip (ESL SoC) and circuit, and adds external power interface, voltage conversion, programmable switch, drive circuit, light source device, etc.; with the help of electronic tag positioning system, intelligent shelf positioning system, store map information service, etc., the AI ​​light source equipment is positioned; based on the above-mentioned communication protocols, hardware systems and positioning systems, etc., AI intelligent fill light based on private protocols, Bluetooth (BT), wireless local area network (WiFi) and other electronic tag wireless communication systems is realized.

[0231] In one embodiment, the electronic price tag power maintenance device includes an artificial intelligence shelf;

[0232] Artificial intelligence shelves, including:

[0233] a fourth electronic price tag positioning module, configured to determine a fourth electronic price tag to be charged on a different artificial intelligence shelf based on positioning information in the electronic price tag status information carried by the power maintenance instruction;

[0234] The fourth charging module is used to call the charging method corresponding to the electronic price tag power management strategy carried by the power maintenance instruction, and charge the fourth electronic price tag to be charged on different artificial intelligence shelves.

[0235] First, the fourth ESL positioning module on the AI ​​shelf is responsible for accurately locating each ESL. By receiving ESL status information carried in power maintenance instructions, this module can quickly identify ESLs that need charging and transmit their location information to the charging module.

[0236] Secondly, the fourth charging module adopts the corresponding charging method to charge the ESL according to the ESL power management strategy. This flexible charging method can be adjusted according to the actual power level of the ESL and charging needs, ensuring charging efficiency while reducing losses during the charging process.

[0237] Furthermore, AI-powered shelves feature data analysis and remote monitoring. By analyzing the charging status and inventory data of electronic price tags, the shelves can intelligently adjust charging and inventory management strategies to achieve optimal operational results. Furthermore, this data can be monitored remotely in real time, allowing merchants to keep abreast of product inventory and charging status, enabling them to make informed decisions.

[0238] The implementation of AI shelves is illustrated by a specific example. As shown in Figure 10, the electrical system and typical physical appearance of the AI ​​shelf include the following key devices or modules: wireless communication systems such as proprietary protocols / BT / WiFi; the smart shelf equipment is based on the electronic price tag circuit, retaining modules such as RF, NFC, ESL SoC chips and circuits, while adding external power interfaces, voltage conversion, programmable switches, drive circuits, fill light sources, as well as near-field coupling power devices, wireless power transmission equipment, physical power supply interfaces, etc.; the shelf itself and the electronic price tag have a unique ID within the electronic price tag system, and based on the electronic price tag positioning system, the smart shelf positioning system, the store map information service, etc., they achieve self-positioning and establish a binding relationship with the electronic price tags deployed in this shelf; based on the above communication protocols, hardware systems, store positioning systems, etc., the electronic price tags can be recharged through the smart shelf.

[0239] In one implementation, intelligent hardware devices are used to maintain the battery life of price tags, including but not limited to the following: AI inspection robots, AI light sources, PDA terminals, AI shopping carts, and AI shelves. These devices possess AI positioning or navigation capabilities and are equipped with one or more of a remote-controlled light source module, a radio energy transmission module, a near-field coupling module, and other devices.

[0240] Smart hardware devices play an important role in maintaining the power consumption of price tags. The following is a detailed introduction to several smart hardware devices and their application scenarios:

[0241] 1. AI Inspection Robot: This AI inspection robot automatically checks the battery level of shelf labels and transmits the results to the backend management system in real time. By analyzing this data, administrators can promptly understand the battery status of labels in each area and provide early warning of low battery levels, thereby improving operational efficiency. Furthermore, the AI ​​inspection robot can recharge itself, ensuring a fully charged battery during extended operation.

[0242] 2. AI Lighting: The AI ​​lighting system not only provides optimal lighting for products but also monitors the battery level of price tags in real time through light sensors. If a powered price tag detects low battery, the AI ​​light source automatically adjusts the light intensity to provide sufficient energy for the tag. Furthermore, the AI ​​light source can work collaboratively with other smart hardware devices to achieve intelligent control of lighting and price tag battery life.

[0269] A specific embodiment is given below to illustrate the specific application of the method of the present application. In this embodiment, the following steps may be included:

[0270] The solar electronic price tag power monitoring and maintenance platform mainly includes an AI intelligent analysis and decision-making module. By analyzing the data information reported by the price tags and based on various big data parameters and strategies preset in the platform, it automatically generates early warning and maintenance plans for the reported price tags or price tag groups.

[0271] 1) The platform is located in the ESL business system. The core part is the background program located in the cloud or local server (the ESL power monitoring and maintenance platform in the ESL business system), which mainly includes the following parts:

[0272] a) Price tag information extraction module: Decodes and extracts data such as energy storage device type, sampled temperature data, solar cell type identification, and illumination data reported on price tags through wireless communication systems such as proprietary protocols / BT / WiFi;

[0273] b) AI intelligent analysis and decision-making module: By analyzing the data information reported by price tags and based on various big data parameters and strategies preset in the platform, it automatically generates early warning and maintenance plans for the price tags or price tag groups reported. The details are as follows:

[0274] Electronic shelf tags proactively report parameters such as voltage and battery life to the backend server, or predict the duration of a low battery condition. The backend server's data analysis module selects ESLs nearing low battery based on voltage thresholds, battery thresholds, or low battery duration thresholds. The backend server then ranks the shelves and aisles requiring recharging based on the physical locations of these ESLs. The number of shelves requiring recharging forms the basis for the sorting algorithm, while the number of ESLs requiring recharging on all shelves within an aisle forms the basis for the aisle sorting algorithm. The decision-making system combines these sorting results and prioritizes the locations of priority recharging areas, either by shelf or aisle, or by aisle first, then shelf.

[0275] Early warning and maintenance instruction interaction module: Based on the early warning and maintenance plan generated by the AI ​​intelligent analysis and decision module, it is responsible for scheduling and monitoring the early warning and maintenance operations of various price tags and various price tag power intelligent maintenance hardware equipment;

[0276] c) The typical deployment location of the electronic price tag power monitoring and maintenance platform is the cloud server or local server where the price tag business management system is located (as shown in Figure 2);

[0277] d) The typical architecture of the intelligent service system for the ESL power monitoring and maintenance platform is shown in Figure 11. The intelligent service system for the ESL power monitoring and maintenance platform is an embedded subsystem of the ESL management system. It monitors and schedules the lower-layer devices of the ESL system through the service layer interface and application layer interface of the ESL.

[0278] 2) The information extraction and intelligent analysis and decision-making process of the electronic price tag power monitoring and maintenance platform is shown in Figure 12:

[0279] a) The platform receives information such as ambient light intensity, energy storage device voltage or power, backup battery voltage or power, location parameters, and radio transceiver parameters reported by electronic price tags or other devices, identifies ESL status information, and generates corresponding maintenance strategies based on preset maintenance strategies or parameters.

[0280] b) The electronic price tag power monitoring and maintenance platform generates a specific ESL power maintenance plan based on the generated maintenance strategy, the map information and navigation services preset in the system, the built-in ESL positioning system and ESL positioning information, the positioning information of the AI ​​device, etc. The maintenance plan includes but is not limited to the following methods:

[0281] 1. Dispatch the required power to maintain the intelligent light source equipment near the light energy price tag, perform ambient light supplement, etc., to increase the energy collected by the light energy price tag, that is, to increase the collected electrical energy.

[0282] 2. The map information, location information, navigation path, etc. are transmitted to the AI ​​inspection robot, which is then dispatched to the designated target price tag and its power is maintained through various methods such as fill light, radio, and near-field coupling.

[0283] 3. Dispatch the smart shopping cart and match it to the target price tag requiring maintenance based on its positioning information. When the smart shopping cart reaches the target price tag requiring power maintenance, power maintenance is achieved through various methods such as fill light, radio, and near-field coupling.

[0284] 4. When solar price tags are deployed on smart shelves with power maintenance functions, the smart shelves where the price tags that need maintenance are located are dispatched based on their positioning information. Through various methods such as fill light, radio, and near-field coupling, power maintenance is achieved for the solar price tags that need power maintenance.

[0285] 5. The map information, location information, navigation path, etc. are transmitted to the price tag maintenance personnel, who then arrive at the target price tag that needs power maintenance. Through devices such as PDAs, power maintenance of the target price tag is achieved through various methods such as direct lead charging, fill light, wireless, and near-field coupling.

[0286] Figure 12: The information extraction and intelligent analysis and decision-making process of the electronic price tag power monitoring and maintenance platform also includes:

[0287] c) The ESL power monitoring and maintenance platform monitors ESLs in real time after maintenance, collecting information such as their operating status, ambient light intensity, and power consumption, and evaluates the effectiveness of maintenance. Based on the evaluation results, the platform optimizes maintenance strategies to improve power maintenance effectiveness.

[0288] d) The platform accumulates relevant data and experience from the maintenance process to form a maintenance knowledge base. This knowledge base can be used to optimize existing maintenance strategies, improve maintenance efficiency, and provide a reference for other similar scenarios of electronic price tag power maintenance.

[0289] e) The ESL power monitoring and maintenance platform continuously learns and optimizes to adapt to changes in the environment and the demands of ESLs. This continuous optimization makes power maintenance more intelligent and automated, reducing labor costs and improving service quality.

[0290] f) The platform can also be combined with other intelligent systems, such as intelligent warehousing and logistics management systems, to achieve comprehensive intelligent management of electronic price tags. Through data sharing and collaborative work, the efficiency and competitiveness of the entire supply chain can be improved.

[0291] In short, the ESL power monitoring and maintenance platform achieves intelligent maintenance for ESLs through information extraction, intelligent analysis and decision-making, and real-time monitoring. This not only improves the stability and reliability of ESLs, but also reduces operating costs and improves service quality for retailers. With the continuous development and optimization of technology, the application prospects of the ESL power monitoring and maintenance platform will become even broader.

[0292] 3) The location information service module of store shelves and electronic price tags, as shown in Figure 13, in the application environment, the shelf information can be displayed through a floor plan of a specific scale, and each shelf and aisle is marked with a corresponding number. Based on the marked coordinate information, the position of the corresponding shelf in the map can be determined. The positioning of the electronic price tag system usually relies on wireless communication technologies and positioning algorithms such as private protocols / Bluetooth / WiFi to track and locate the exact location and movement status of the electronic price tag. An algorithm based on neighbor positioning can effectively achieve precise positioning of electronic price tags in supermarkets. Such systems help merchants to achieve precise control and management of electronic price tags in stores, covering aspects such as positioning, quotation updates and inventory management.

[0293] The location information service module provides a method and system for accurately locating electronic shelf tags within supermarkets using a neighbor positioning algorithm. For example, the system can determine the relative position of electronic shelf tags by analyzing the communication signal strength between them and the signal strength between the electronic shelf tags and the base station, thus achieving precise positioning without the need for additional hardware.

Furthermore, by analyzing customer shopping behavior, personalized promotional information and shopping guide services can be provided to customers.

[0305] 2. Intelligent Inventory Management: By monitoring the location of electronic price tags in real time, merchants can understand the inventory status of goods and replenish them in a timely manner to avoid stockouts. In addition, combined with sales data, merchants can also analyze hot and slow-moving goods, thereby adjusting product structure and increasing sales.

[0306] 3. Energy saving and emission reduction: Supermarkets can achieve the goal of energy saving and emission reduction by analyzing the real-time number of people and activities in the area where the electronic price tags are located, and intelligently adjust the switches and power of lighting, air conditioning and other equipment.

[0307] 4. Safety Monitoring: With the precise positioning technology of electronic shelf labels, supermarkets can monitor the distribution of personnel in real time and improve safety management.

[0309] The precise positioning system for electronic shelf labels (ESLs), based on a neighbor positioning algorithm, has broad application prospects within supermarkets. By continuously optimizing and improving the system's functionality, it can provide merchants with more efficient and convenient management tools, improve overall supermarket operations, and maximize commercial value. This system also contributes to enhancing the customer shopping experience and promoting the sustainable development of the supermarket industry. In the future, we look forward to seeing this technology being widely applied in even more areas, bringing greater convenience to people's lives.
