[0046] The following application will describe the technical solutions in the embodiments of this application in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0047] It should be noted that the terms "first", "second", "target", "candidate", "alternative" and the like in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0048] It should be noted that, for the terminal positioning problem in supermarket scenarios, the existing solutions are mostly to deploy multiple independent systems at the same time in the supermarket venue: WLAN system, price tag system, positioning system, to respectively solve the user's broadband data communication needs, electronic price tag management needs and positioning business needs. However, multiple systems dispersed in the same venue can partially solve the user's needs in actual applications, but this non-inherently unified multi-system combination solution will encounter many problems in actual implementation, such as: 1. Separate installation is required during construction deployment; 2. The control interfaces of multiple systems are independent of each other, which makes it difficult to uniformly manage and coordinate functions during user use; 3. The working frequency bands of multiple systems may overlap, and mutual interference on the RF channel during operation is difficult to avoid. In response to the above problems, this application proposes a solution to distribute configuration information and allocate working channels to different terminals through the interaction of servers, integrated base stations and terminals, so as to achieve real-time and precise positioning of terminal devices. It deeply integrates the price tag management system with clear requirements of the supermarket industry with broadband services and precise positioning services, and integrates multiple sets of hardware and software that were originally independent of each other from the design source, so that multiple systems can work together to realize unified digital management of shelf goods and supermarket assets. The implementation method will be introduced in subsequent embodiments.

[0049] Example 1

[0050] Figure 1A is a flow chart of a terminal positioning method provided in Example 1 of the present application; Figure 1B is a schematic diagram of the structure of a fusion base station provided in Example 1 of the present application; this embodiment is applicable to situations where the fusion base station interacts with the target terminal based on target configuration information sent by the server to achieve accurate positioning of the target terminal. The method can be executed by a terminal positioning device, which can be implemented in software and / or hardware and can be integrated into an electronic device with terminal positioning capabilities. As shown in Figure 1A, the terminal positioning method includes the following steps.

[0051] S101. If target configuration information sent by the server is detected, the target configuration information and the working channel of the target terminal are sent to the target terminal according to the sending time of the target configuration information, so as to instruct the target terminal to feed back a positioning signal to the fusion base station based on the target configuration information and the working channel.

[0052] The target terminal may be a terminal equipped with a radio frequency signal transmitting component, such as an ultra-wideband (UWB) signal transmitter, an angle-of-arrival (AOA) signal transmitter, or other wireless signal transmitter. The target terminal may utilize the radio frequency signal transmitting component to interact with the fusion base station for positioning. The target terminal may be placed in a supermarket, and there may be at least one target terminal.

[0053] The target terminal may be a terminal device in a supermarket, and may include a narrowband electronic shelf label (ESL). The electronic shelf label is a form of terminal that can be installed in a supermarket through actual hardware. ESL price tags may include ink screen (Electrophoresis Display, EPD) price tags and liquid crystal display (Liquid Crystal Display, LCD) price tags. The target terminal may also include terminals that integrate narrowband and broadband modules, such as shopping carts, smart cameras, and robots, and may also include location tags that integrate narrowband and positioning modules. Target configuration information refers to configuration information that needs to be sent to the target terminal to instruct the target terminal to send a positioning signal. The target configuration information may include the period and number of times the target terminal sends a positioning signal to the fusion base station.

[0054] Optionally, referring to FIG1B , the fusion base station includes a narrowband module, a positioning module, and a broadband module. Accordingly, the target configuration information and the target terminal's operating channel are transmitted to the target terminal based on the target configuration information's transmission time, including: determining the target configuration information's transmission time and the target terminal's operating channel based on the operating states of the narrowband module, positioning module, and broadband module of the fusion base station; and transmitting the target configuration information and the operating channel to the target terminal based on the transmission time.

[0055] Optionally, if the local narrowband module, positioning module and broadband module of the fusion base station are in the working state of business data reception and transmission processing, it is necessary to wait until the business data reception and transmission is completed before sending the target configuration information. Accordingly, the sending time of the target configuration information is determined according to the working state of the local narrowband module, positioning module and broadband module of the fusion base station, including: if the working state of the local narrowband module, positioning module and broadband module of the fusion base station is the working state of business processing, the sending time of the target configuration information is determined according to the target time required for the completion of business processing; if the working state of the local narrowband module, positioning module and broadband module of the fusion base station is the stopped working state, the sending time is determined to be the current moment, and then the narrowband module is called to send the target configuration information to the target terminal at the current moment.

[0056] It should be noted that the above method can avoid sending target configuration information when multiple modules of the fusion base station are sending and receiving business data, so as to ensure that the sending process of configuration information will not be interfered by business data, thereby improving the reliability of configuration information sending.

[0057] Optionally, the fusion base station can send the target configuration information and the working channel of the target terminal to the target terminal based on the working channel of the target terminal, or it can directly send the target configuration information and the working channel of the target terminal to the target terminal based on the working channel of its local narrowband module. This application does not impose any restrictions on this.

[0058] The fusion base station can send the target configuration information and the working channel to the target terminal at the same time according to the sending time of the target configuration information and the working channel of the target terminal, so as to instruct the target terminal to feedback the positioning signal to the fusion base station through the corresponding working channel according to the target configuration information.

[0059] Optionally, the target terminal may send a positioning signal on the allocated working channel at a specified period based on the received target configuration information.

[0060] Optionally, determining the working channel of the target terminal includes: if the working status of the local broadband module of the fusion base station is a stopped working state, then using the preset default working channel as the working channel of the target terminal; if the working status of the local broadband module of the fusion base station is a working state or a paused working state, then determining the current channel of the broadband module, and based on the current channel, screening out a target channel different from the current channel from the candidate channels as the working channel of the target terminal.

[0061] The stopped working state of the broadband module is a pre-specified state in which the broadband module will not be enabled to work for a long time or permanently, and the suspended working state is a pre-specified state in which the broadband module temporarily stops working for a short period of time.

[0062] Optionally, based on the current channel, a channel as far away as possible from the current channel being used by the broadband service module may be selected from the candidate channels as the target channel.

[0063] Optionally, after determining the current channel of the broadband module, the center frequency of the current channel of the broadband module can be determined. Based on the center frequency and the preset isolation bandwidth, channels outside the preset isolation bandwidth from the center frequency are determined as candidate channels, and a target channel different from the current channel is screened out from the candidate channels, wherein the impact of the broadband signal on the reception of the positioning signal is less than the effective signal-to-noise ratio threshold of the positioning signal.

[0064] The target channel obtained by the above method can be centered on the center frequency and extended to the left and right by a preset isolation bandwidth, so that the working channel of the broadband module and the working channel of the target terminal can be separated, effectively improving the working efficiency of the broadband module and subsequent interaction with the target terminal.

[0065] It should be noted that the optional range of the working channels of multiple modules of the fusion base station is within the frequency of 2.4GHz-2.5GHz, which is overlapping, so they need to be staggered through configuration, that is, configured on different channels (frequencies). By screening out the target channel that is different from the current channel from the candidate channels, the working channels of multiple modules of each fusion base station can be staggered in frequency, thereby improving work efficiency.

[0066] It should be noted that a narrowband channel of the target terminal can be set to receive the configuration information sent by the fusion base station. If it is not fixed, the base station needs to reallocate it each time. This process will affect work efficiency. By fixing the communication channel, work efficiency can be improved.

[0067] Optionally, the fusion base station can also interact with the server's integrated management platform to obtain other configuration information (such as price tag display information, broadband terminal Internet Protocol (IP) address, robot business travel speed and other configuration information), and send the configuration information to the target terminal to achieve three-way interaction for business processing.

[0068] S102: Acquire a positioning signal fed back by the target terminal, and perform preliminary calculation processing on the positioning signal to convert the positioning signal into position information.

[0069] Optionally, the positioning signal receiving module inside the fusion base station can obtain the positioning signal fed back by the target terminal through the corresponding working channel based on the preset target channel corresponding to each target terminal, and perform preliminary processing in the base station.

[0070] Exemplarily, the positioning signal may be preliminarily solved based on a preset positioning algorithm, such as an AOA positioning algorithm, to convert the positioning signal into position information.

[0071] S103: Send the location information to the server to instruct the server to update and display the locally stored map information according to the location information to achieve positioning of the target terminal.

[0072] Optionally, the fusion base station can upload the solved location information to the positioning service server module on the server side through the network, that is, send the location information to the server to instruct the server to perform final processing on the received location information and display and mark it on the map.

[0073] It's important to note that the converged base station, through its narrowband module, controls the communication behavior of all modules in the system. This allows the integrated management platform or the converged base station itself to coordinate the wireless spectrum resources used by various services, preventing the inevitable radio frequency interference that occurs in previously decentralized systems. For example, the aforementioned process accounts for the interference of WLAN 2.4GHz signals with AOA positioning signals. This coordinated scheduling significantly improves the availability and robustness of the entire solution, a key value proposition of the converged base station.

[0074] It should be noted that the solution proposed in this application integrates the positioning business and broadband business that are urgently needed in the supermarket field on the basis of the existing electronic price tag business of supermarkets, and operates and maintains them through a unified comprehensive management platform, so that coordination between multiple businesses can be easily achieved. While meeting customers' needs for digital management of product prices, it can also meet the needs of precise positioning of shelves, products, and hot spots, thereby improving employee work efficiency and enhancing operational benefits.

[0075] The technical solution of the embodiment of the present application is that if the fusion base station detects the target configuration information sent by the server, it will send the target configuration information and the working channel of the target terminal to the target terminal according to the sending time of the target configuration information, so as to instruct the target terminal to feedback the positioning signal to the fusion base station based on the target configuration information and the working channel of the target terminal; obtain the positioning signal fed back by the target terminal, and perform preliminary solution processing on the positioning signal to convert the positioning signal into location information; send the location information to the server to instruct the server to update and display the locally stored map information according to the location information to realize the positioning of the target terminal. In this way, the target terminal can be accurately positioned through the interaction of the server, the fusion base station and the target terminal, so that multiple systems of the supermarket can work together to realize the unified digital management of shelf goods and supermarket assets.

[0076] It's important to note that the functional modules within the converged base station can be individually enabled or disabled to meet the needs of different user scenarios. For example, in the early stages of a customer project, if only the electronic price tag service is required, the broadband and positioning modules can be temporarily disabled to save system power. As needs evolve, such as introducing robot patrol services and real-time positioning of shopping carts, the broadband and positioning services can be enabled in turn.

[0077] It should be noted that the fusion base station deeply integrates the price tag business, positioning business and broadband communication business with clear demand in the supermarket field. A set of systems can be used to solve users' various business needs. At the same time, the fusion base station realizes unified management and scheduling of narrowband, broadband and positioning services, so as to better meet the business needs of the supermarket field. Compared with the original solution obtained by combining scattered equipment, the system availability and robustness constructed according to the solution of this application will be greatly improved. It can also achieve radio frequency channel avoidance according to the user's business status to avoid conflicts between multiple services.

[0078] Optionally, the fusion base station of the present application integrates a WLAN broadband service module in hardware, and a broadband service server is configured in the server, which enables multiple base stations to cooperate in using the received signal strength of the broadband WLAN signal for triangulation positioning. For supermarket terminal devices with large data transmission and reception requirements, such as shopping carts and robots, broadband service modules can be integrated. For example, robots can upload the pictures and video information they obtain to the integrated management platform through the integrated WLAN module. The integrated management platform can be a remote Software as a Service (SaaS) or a local business management platform. Compared with the multiple management interfaces of a decentralized system, the integrated management platform can more conveniently and effectively manage and coordinate multiple businesses in the entire system, thereby enhancing user value.

[0079] The converged base station can also integrate a narrowband module, corresponding to the narrowband service server in the server. If the target terminal needs to coordinate services through the converged base station, it can receive small amounts of information from the integrated management platform forwarded by the converged base station through the integrated RF signal receiving component. Configuration information such as price tag display information, broadband terminal IP address, and robot service travel speed can all be distributed by this narrowband module.

[0080] Within the converged base station, the hardware integrates a positioning service receiving module, a broadband service module, and a price tag service module (narrowband module). These modules interact with the positioning service antenna, narrowband service antenna, and broadband WLAN service antenna, respectively, enabling unified coordination of antenna transmission and reception for multiple services, preventing interference and improving system robustness. Software-wise, the operation of multiple modules is coordinated based on service needs. This makes the converged base station not a simple hardware bundle, but rather a system inherently integrated with multiple components. For example, based on service needs, the narrowband module can deliver configuration information required for positioning services. The narrowband module then exchanges information with terminals requiring broadband communication to schedule broadband service access. When the server-side positioning service module initiates a positioning operation for a specified target terminal (e.g., a shopping cart integrating narrowband and positioning modules) based on user instructions or established policies, it can execute operations S101-S103 described above to accurately locate the target terminal.

[0081] Example 2

[0082] Figure 2 is a flowchart of a terminal positioning method provided in Example 2 of this application. This embodiment is applicable to situations where a server interacts with a fusion base station based on the positioning requirements of a target terminal to achieve precise positioning of the target terminal. This method can be performed by a terminal positioning device, which can be implemented using software and / or hardware and can be integrated into an electronic device with terminal positioning capabilities. As shown in Figure 2, the terminal positioning method includes the following steps.

[0083] S201: Determine target configuration information to be sent to the target terminal according to the positioning requirement of the target terminal.

[0084] Positioning requirements refer to the need to set different positioning information transmission modes based on different terminal types or the user's positioning requirements for the target terminal during actual use.

[0085] It should be noted that the server can receive positioning requirements for the target terminal issued by relevant personnel, and determine the working mode of the target terminal specified in the positioning requirements, and determine different positioning signal sending strategies for different target terminals according to the working mode, which can be a positioning signal sending strategy with a specified period and number of times.

[0086] It should be noted that the software in the server may include a narrowband service server, a broadband service server, a positioning service server and a comprehensive service management platform. According to the positioning requirements of the target terminal, the positioning service server module of the server may submit the target configuration information to the narrowband service server module on the server side.

[0087] Optionally, determining the target configuration information to be sent to the target terminal includes: if the working mode of the target terminal is a fixed mode, determining the target configuration information to be sent to the target terminal based on the first period and the first number; if the working mode of the target terminal is a mobile mode, determining the target configuration information to be sent to the target terminal based on the second period and the second number.

[0088] The target terminal in fixed mode can be an electronic shelf label or a smart camera. The target terminal in mobile mode can be a shopping cart or a robot. The first period is greater than the second period; the first number is less than the second number.

[0089] For example, the EPD price tags, LCD price tags, and cameras on the shelves are relatively fixed and can send positioning signals every 1-2 hours; shopping carts and robots are generally in a mobile state, so the frequency of sending positioning signals must be higher. For example, a shopping cart needs to send a positioning signal once per second. In this way, resource waste can be reduced.

[0090] S202: Send the target configuration information to the fusion base station to instruct the fusion base station to send the target configuration information and the working channel to the target terminal according to the sending time of the target configuration information.

[0091] Among them, the internal hardware of the fusion base station includes an uplink network module, a narrowband module (for small data volume communication, such as the transmission of ESL price tag information, camera or robot device configuration information), a WLAN broadband module (for large data volume communication, such as the transmission of images and video data collected by cameras and robots) and a positioning module (for the reception and preprocessing of positioning signals emitted by location tags), etc.; the fusion base station management platform software inside the fusion base station is responsible for the coordination of multiple hardware modules of the base station itself. The sending time refers to the time when the fusion base station sends the target configuration information to the corresponding target terminal. The working channel refers to the communication frequency between the target terminal and the different modules of the fusion base station. The optional working channel range of the narrowband module, broadband module and positioning module of the fusion base station is all within the frequency range of 2.4GHz-2.5GHz. For example, the narrowband module can use 2.402GHz, the positioning module can use 2.480GHz, and the broadband module can use 2.462GHz.

[0092] It should be noted that in the fusion base station, the working channel of the narrowband module can be preset to a fixed value; the working channel of the broadband module can be allocated on-site during network deployment, or it can be dynamically selected by the fusion base station according to the radio frequency environment in which it is located, that is, the working channel of the width module may be a variable value; the channel used by the positioning module needs to avoid the channels currently used by the above narrowband module and broadband module, for example, the narrowband module uses 2.402GHz, the broadband module uses 2.462GHz, and the positioning module uses 2.480GHz.

[0093] It should be noted that the fusion base station includes a price tag service module, a positioning service module, and a broadband service module. The spectrum resources occupied by the above modules when working can be coordinated uniformly by the processor of the fusion base station.

[0094] Optionally, the server can also obtain the real-time working status of multiple business modules through its internal fusion management platform, and allocate a suitable working channel to the target terminal, and send the allocated working channel and target configuration information to the fusion base station to instruct the fusion base station to send the target configuration information and the allocated working channel to the target terminal.

[0095] Optionally, after determining the target configuration information to be sent to the target terminal, the server can use the narrowband service server-side module on the server side to communicate with the fusion base station to send the target configuration information to the fusion base station, instruct the fusion base station to determine the sending time and working channel of the target configuration information, and send the target configuration information and working channel to the target terminal according to the sending time.

[0096] S203: Acquire the location information fed back by the fusion base station, and update and display the locally stored map information based on the location information to achieve positioning of the target terminal.

[0097] Optionally, the locally stored map information is updated and displayed based on the location information, including: determining the historical coordinates of the target terminal in the locally stored map, and judging whether the deviation between the current coordinates of the target terminal in the location information and the historical coordinates is within a preset deviation range; if the deviation between the current coordinates of the target terminal in the location information and the historical coordinates is within a preset deviation range, the locally stored map information is updated according to the current coordinates, and the updated map is displayed to relevant personnel.

[0098] Optionally, different preset deviation ranges can be set for target terminals in fixed mode and mobile mode according to the working mode of the target terminal. For example, a target terminal with a fixed working mode allows a small deviation range. If the deviation is too large, it is considered unreasonable. A target terminal with a mobile working mode allows a large deviation range. If the deviation is too small, it can be considered that there is no movement and no update is performed at this time, and an error reminder of the target device is issued.

[0099] Optionally, the target terminal is also configured to send a service coordination request to the fusion base station.
