[0024] The following is an explanation and description of the technical solutions of the embodiments of this specification in conjunction with the drawings of the embodiments of this specification, but the following embodiments are only preferred embodiments of this specification, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of this specification.

[0025] The terms "first", "second", "third", etc. in the description and claims of this specification and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. 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 that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.

[0026] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate directions or positional relationships are only used to facilitate the description of the embodiments and simplify the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation of this specification.

[0027] The data involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection of relevant data complies with the relevant laws, regulations and standards of relevant countries and regions.

[0028] This embodiment provides a new type of ESL positioning electronic price label 10, see the attached Figure 1 and attached Figure 2 The electronic price tag 10 includes a panel 12, a display screen 13, a base 14, a camera 11, a display screen controller 21, a positioning chip 22, a communication module 24, a power supply module and a controller 23. The panel 12 is mounted on the base 14, the display screen 13 is embedded in the panel 12, and the camera 11 is mounted on the panel 12. Please refer to the attached Figure 3, the display screen controller 21, positioning chip 22, communication module 24, power supply module and controller 23 are all installed in the base 14. The display screen 13 can display information such as product name, product specifications, product price, production date, barcode, etc., which is convenient for consumers to purchase. When the supermarket needs to adjust the price or information of a certain product, the price change information is sent through the communication module 24, and then the display controller 21 controls the display to display. The supermarket adjusts the price and other information with high efficiency. As a recommended method, the positioning electronic price tag 10 adopts an ink screen, which can save electricity with its low power consumption characteristics. At the same time, the ink screen has a good viewing angle and contrast, and can provide clear and readable text display effects under various lighting conditions. The camera 11 can determine whether there are consumers approaching, so that the flow of consumers can be counted.

[0029] Please see attached Figure 4 , multiple electronic price tags 10, employee badges 40, multiple positioning base stations 60 and the server 30 cooperate with each other to realize the positioning and display of the electronic price tag 10. Among them, the controller 23 of the electronic price tag 10 establishes a communication connection with the server 30 through the communication module 24, the employee badge 40 is built with a positioning chip 22, a second communication module 24 and a second controller 23, the second controller 23 uploads the location information of the employee badge 40 to the server 30 through the second communication module 24, and multiple positioning base stations 60 are distributed in the sales area 50. The positioning chip 22 establishes a communication connection with the positioning base station 60, and the server 30 controls the display content of the electronic price tag 10 according to the location information of the employee badge 40 and the electronic price tag 10.

[0030] For example, please see the attached Figure 5 , is a plan distribution diagram of a supermarket used in this embodiment. There are multiple shelves 51 distributed in the supermarket, and multiple positioning base stations 60 are distributed within the supermarket. As a recommended method, the positioning base stations 60 are distributed on the top of the supermarket. Among them, the positioning chip 22 includes a processor and a Bluetooth receiving module, the positioning base station 60 includes a Bluetooth broadcasting module, and the processor of the Bluetooth broadcasting module of the positioning base station 60 is connected to the Bluetooth receiving module.

[0031] When the processor obtains the location information from the positioning base station 60, the processor performs the following steps: receiving broadcast information including base station numbers and base station locations broadcasted by at least four positioning base stations 60; Calculate the distance to the corresponding broadcast base station based on the signal strength of the received broadcast information; The own position information is obtained according to the distances from the four positioning base stations 60 and the base station positions of the positioning base stations 60 .

[0032] Bluetooth itself does not directly support positioning, but by analyzing the strength of Bluetooth signals received from multiple positioning base stations 60, the relative distance between the receiving device and each base station can be estimated. This method is called RSSI (Received Signal Strength Indication) ranging method. In theory, as long as there are more than four positioning base stations 60 with known locations, the three-dimensional coordinates can be calculated using the triangulation principle to achieve the purpose of accurate positioning.

[0033] Receive broadcast information including base station numbers and base station locations broadcast by at least four positioning base stations 60. Each positioning base station 60 will periodically broadcast its unique base station number and the coordinates of the known base station location (usually X, Y, Z coordinates). These broadcast information is captured by the electronic price tag 10 (ESL) or other devices with receiving capabilities through wireless communication protocols such as Bluetooth low energy broadcast (BLE). When the ESL receives these broadcast information, it estimates the distance between each base station based on the strength of the received signal. This process involves the application of received signal strength indication (RSSI, ReceivedSignal Strength Indication) technology. RSSI is a method of measuring the strength of radio waves, usually expressed in decibel milliwatts (dBm). Ideally, the closer you are to the base station, the stronger the received signal; otherwise, the weaker it is.

[0034] However, there are many factors in the actual environment that may affect signal propagation, such as attenuation or reflection caused by obstacles such as walls and human bodies. Therefore, the distance calculation based on RSSI is not completely accurate, but it can provide a relatively accurate estimate. In order to improve positioning accuracy, the system usually uses multiple base stations for triangulation or multilateral measurement. When receiving broadcast information from four different base stations, and being able to extract their respective numbers, locations and corresponding RSSI values. Then convert RSSI into actual distance. This step can be done through a preset empirical formula or machine learning model.

[0035] Once the approximate distances from the ESL to each base station are obtained, mathematical methods, such as the least squares method, can be used to calculate the exact location of the ESL. Specifically, the location coordinates of the four base stations are (x1, y1, z1), (x2, y2, z2), (x3, y3, z3) and (x4, y4, z4), and the distances between the positioning chip 22 and the four positioning base stations 60 are d1, d2, d3 and d4, respectively. By solving the following nonlinear equations: (x - x1)^2 + (y - y1)^2 + (z - z1)^2 = d1^2 (x - x2)^2 + (y - y2)^2 + (z - z2)^2 = d2^2 (x - x3)^2 + (y - y3)^2 + (z - z3)^2 = d3^2 (x - x4)^2 + (y - y4)^2 + (z - z4)^2 = d4^2 Among them, (x, y, z) represents the position coordinates of the positioning chip 22. Since this is an overdetermined problem, that is, the number of equations is greater than the number of unknowns, the least square method or other numerical optimization algorithms can be applied to find the best fitting solution to obtain the position information closest to the actual situation. After calculation, the position information of the positioning chip 22 itself can be finally obtained.

[0036] The server 30 involved in the present application can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery networks (Content Delivery Network, CDN), as well as big data and artificial intelligence platforms.

[0037] Please refer to the attached Figure 6 , the electronic price tag 10 is placed on the shelf 51 and is used to identify the product name, price and other relevant information. In this embodiment, when controlling the electronic price tag 10 to display the goods sales information and goods management information, the three-dimensional coordinates are used to represent the position of the electronic price tag 10. When used to determine the distance between the electronic price tag 10 and the employee card 40, the vertical coordinate is ignored, and only the horizontal coordinate is used to calculate the distance. That is, the (x, y) coordinates are used to calculate the distance between the electronic price tag 10 and the employee card 40. Therefore, when the employee card 40 is located near an electronic price tag 10, the electronic price tags 10 with the same or close vertical coordinates as the electronic price tag 10 will display the goods management information. This can not only reduce the amount of calculation, but also conform to the actual operation. Supermarket employees can operate a vertical row of goods at the same location.

[0038] Please refer to the attached Figure 7 And attached Figure 8 When the server determines whether the distance between the electronic price tag 10 and the employee badge 40 is less than the preset distance, the server performs the following steps: A trigger circle is defined for each electronic price tag 10, wherein the trigger circle is a circle with the position of the electronic price tag 10 as the center and a preset distance as the radius; Receive the position information reported by the employee badge 40, and determine whether the employee badge 40 is within any trigger circle; If the employee badge 40 is outside any trigger circle, the circumscribed circle of the nearest trigger circle is obtained with the current position of the employee badge 40 as the center; The radius of the circumscribed circle is issued to the employee badge 40, and the employee badge 40 is instructed not to report the position information until it exceeds the range of the circumscribed circle; If the employee badge 40 is within a trigger circle, the inscribed circle of the trigger circle is obtained with the current position of the employee badge 40 as the center; The radius of the inscribed circle is issued to the employee badge 40 , and the employee badge 40 is instructed not to report position information until it exceeds the range of the inscribed circle.

[0039] Specifically, the process of the server 30 controlling the display of the electronic price tag 10 is as follows: the employee badge 40 reports its own location information; the server 30 determines whether the employee badge 40 is close enough to any electronic price tag 10, that is, whether the distance is less than the preset distance. When there is no electronic price tag 10 that is close enough to the employee badge 40, no operation is performed, but the next position report of the employee badge 40 is waited for. When there is an electronic price tag 10 that is close enough to the employee badge 40, the corresponding electronic price tag 10 is controlled to display the goods management information, and when the electronic price tag 10 has already displayed the goods management information, the display is maintained. When the reported location information of the employee badge 40 is received and it is found that the employee badge 40 has left the electronic price tag 10 that previously displayed the goods management information, the electronic price tag 10 is controlled to stop displaying the goods management information and display the goods sales information instead.

[0040] When a supermarket employee, such as a stocker, gradually approaches an electronic price tag 10 with an employee badge 40, in order to enable the corresponding electronic price tag 10 to switch to display the goods management information as soon as possible, the employee badge 40 needs to communicate with the server 30 more intensively and inform the server 30 intensively of the current position of the employee badge 40. As a result, the server 30 can control the corresponding electronic price tag 10 to switch the displayed content as soon as possible when the employee badge 40 just enters the trigger circle range. When the electronic price tag 10 displays the goods management information, in order to determine whether the employee badge 40 has left the trigger circle range of the electronic price tag 10, the employee badge 40 is also required to frequently report the current location information, and the server 30 determines whether it has left the trigger circle and controls the corresponding electronic price tag 10 to change back to display the goods sales information. However, such intensive reporting of location information will lead to a large consumption of server 30 resources and occupy more communication bandwidth. When there are many employee badges 40 in the supermarket, or the electronic price tags 10 are relatively dense, the hardware resources of the server 30 will be exhausted, resulting in failures, affecting the normal management of the supermarket.

[0041] To solve this problem, after receiving the position information reported by the employee badge 40, this embodiment first determines whether the employee badge 40 is within any trigger circle. If the employee badge 40 is outside any trigger circle, the circumscribed circle with the current position of the employee badge 40 as the center is obtained. The radius of the circumscribed circle is issued to the employee badge 40, and it is indicated that the employee badge 40 will not report the position information until it exceeds the circumscribed circle range. If the employee badge 40 does not exceed the circumscribed circle range, it is impossible to enter the range of any electronic price tag 10. Therefore, within the circumscribed circle range, the server 30 does not need to receive the position information reported by the employee badge 40. Correspondingly, if the employee badge 40 is within a trigger circle range, the inscribed circle of the trigger circle is obtained with the current position of the employee badge 40 as the center. The radius of the inscribed circle is issued to the employee badge 40, and it is indicated that the position information will not be reported until the employee badge 40 exceeds the inscribed circle range. When the employee badge 40 does not exceed the range of the inscribed circle, it is impossible for the employee badge 40 to leave the trigger circle range, so the server 30 does not need to process the location information of the employee badge 40. That is, it indicates that the employee badge 40 will no longer report the location information when it does not exceed the range of the inscribed circle. It is worth noting that when the radius r1 of the circumscribed circle or the inscribed circle is too small, such as less than r0, the radius of the circumscribed circle and the inscribed circle is set to r0. When the value of r0 is small, the sensitivity of controlling the display of the electronic price tag 10 will be high, but it will cause the corresponding load of the server 30 to increase. When the value of r0 is large, the sensitivity of controlling the display of the electronic price tag 10 will decrease, but the load of the server 30 will decrease accordingly.

[0042] When the processor of the employee badge 40 determines whether the range of the circumscribed circle is exceeded, the following steps are performed: Record the location information reported each time as the center of the circle; When receiving the radius of the circumscribed circle, periodically calculating the distance between the current own position and the center of the circle; When the distance is greater than the radius of the circumscribed circle, it is determined that the employee badge 40 is beyond the range of the circumscribed circle; When the processor of the employee badge 40 determines whether the range of the inscribed circle is exceeded, the following steps are performed: Record the location information reported each time as the center of the circle; When receiving the radius of the inscribed circle, periodically calculating the distance between the current own position and the center of the circle; When the distance is greater than the radius of the inscribed circle, it is determined that the employee badge 40 is beyond the inscribed circle. For this calculation process, the employee badge 40 itself can perform the calculation without communicating with the server 30, which reduces the pressure on the server 30 and does not occupy the network bandwidth.

[0043] On the other hand, this specification provides a novel control method for ESL positioning electronic price tag 10, which is used for controlling the electronic price tag 10 as described above. Fig. 9 , including the following steps: Step S101) receiving the location information of the electronic price tag 10, receiving the goods sales information, goods management information and goods location information; Step S102) Associating the corresponding electronic price tag 10 according to the goods location information, and controlling the electronic price tag 10 to display goods sales information; Step S103) receiving the position information of the employee badge 40, and determining whether the distance between the electronic price tag 10 and the employee badge 40 is less than a preset distance; Step S104) When the distance between the electronic price tag 10 and the employee badge 40 is less than a preset distance, the corresponding electronic price tag 10 is controlled to display the goods management information; and when the distance between the electronic price tag 10 and the employee badge 40 is greater than a preset distance, the corresponding electronic price tag 10 is controlled to display the goods sales information.

[0044] On the other hand, please see the attached Fig.10 The method for determining whether the distance between the electronic price tag 10 and the employee badge 40 is less than a preset distance comprises the steps of: Step S201) defining a trigger circle for each electronic price tag 10, wherein the trigger circle is a circle with the position of the electronic price tag 10 as the center and a preset distance as the radius; Step S202) receiving the position information reported by the employee badge 40, and determining whether the employee badge 40 is within any trigger circle; Step S203) If the employee badge 40 is outside any trigger circle, taking the current position of the employee badge 40 as the center, obtain a circumscribed circle with the nearest trigger circle; Step S204) issuing the radius of the circumscribed circle to the employee badge 40, and instructing the employee badge 40 not to report position information until it exceeds the range of the circumscribed circle; Step S205) If the employee badge 40 is within a trigger circle, the inscribed circle of the trigger circle is obtained with the current position of the employee badge 40 as the center; Step S206) The radius of the inscribed circle is issued to the employee badge 40, and the employee badge 40 is instructed not to report position information until it exceeds the range of the inscribed circle.

Optionally, the processor 1101 can be implemented in at least one hardware form of DSP, FPGA, and PLA. The processor 1101 may integrate one or a combination of a CPU, a GPU, and a modem, etc. The CPU mainly processes the operating system, the user interface, and the application program, etc.; the GPU is responsible for rendering and drawing the content to be displayed on the display screen 13; and the modem is used to process wireless communications.

[0047] It is understandable that the above-mentioned modem may not be integrated into the processor 1101, but may be implemented by a separate chip.

[0048] Among them, the memory 1105 may include RAM or ROM. Optionally, the memory 1105 includes a non-transitory computer-readable medium. The memory 1105 can be used to store instructions, programs, codes, code sets or instruction sets. The memory 1105 may include a program storage area and a data storage area, wherein the program storage area may store instructions for implementing an operating system, instructions for at least one function (such as a touch function, a sound playback function, an image playback function, etc.), instructions for implementing the above-mentioned various method embodiments, etc.; the data storage area may store data involved in the above-mentioned various method embodiments, etc. The memory 1105 may also be at least one storage device located away from the aforementioned processor 1101.

[0049] The embodiments of this specification also provide a computer-readable storage medium, which stores instructions, and when the instructions are executed on a computer or a processor, the computer or the processor executes the multiple steps in the above embodiments. If the components of the above electronic device are implemented in the form of software functional units and sold or used as independent products, they can be stored in the computer-readable storage medium.

[0050] The embodiments of this specification also provide a computer program product, including a computer program, which implements multiple steps in the above embodiments when executed by a processor.

[0051] In the absence of conflict, the technical features in this embodiment and implementation scheme can be combined arbitrarily.

[0052] In the above embodiments, it can be implemented in whole or in part by software, hardware, firmware or any combination thereof. When implemented by software, it can be implemented in whole or in part in the form of a computer program product. The computer program product includes a plurality of computer instructions. When the computer program instructions are loaded and executed on a computer, the process or function described in the embodiment of this specification is generated in whole or in part.

[0053] When implemented by hardware or firmware, the aforementioned method flow is programmed into the hardware circuit to obtain the corresponding hardware circuit structure and realize the corresponding function. For example, a programmable logic device (PLD) (such as a field programmable gate array (FPGA)) is such an integrated circuit, and its logic function is determined by the user programming the device. The designer programs by himself to "integrate" a digital system on a PLD, without asking a chip manufacturer to design and make a dedicated integrated circuit chip. Moreover, nowadays, instead of manually making integrated circuit chips, this programming is mostly implemented by "logic compiler" software, which is similar to the software compiler used when writing program development, and the original code before compilation must also be written in a specific programming language, which is called hardware description language (HDL), and HDL is not just one, but many. Those skilled in the art should also be aware that it is only necessary to program the method flow slightly in the above-mentioned hardware description languages ​​and program it into the integrated circuit to easily obtain the hardware circuit that implements the logic method flow.
