Description

[Technical Field]

[0001] The present invention relates to the technical field of positioning, and more particularly to a method and system for positioning a device using signal direction. [Background technology]

[0002] Electronic shelf labels (also called electronic price tags) installed in physical stores can display prices, making it easier for store managers to centrally manage prices. When store staff manage merchandise in stores, or when customers shop in large stores, there is a common need to quickly find products. To satisfy this need, a technical solution is needed that can accurately determine the position of products and people in the store and guide people's behavior. An electronic shelf label system is a wireless communication system. Moreover, electronic shelf labels have a one-to-one correspondence with products. Wireless communication and signal processing between electronic shelf labels enable the physical location of electronic shelf labels to be obtained, and product locations can also be determined. Summary of the Invention [Problem to be solved by the invention]

[0003] In the conventional technology, the proximity relationship between electronic shelf labels is established mainly through mutual communication and measurement between electronic shelf labels, and the positioning of electronic shelf labels is also possible. However, this solution still has some inconveniences in terms of implementation and deployment, and in some inappropriate scenarios, there are also shortcomings in terms of human positioning.

[0004] Additionally, Ibeacons can be added to a scene to measure people's positions in real time. Ibeacons use wireless signal identifiers for positioning. However, once an object, such as a shelf, in a scene changes, the identifier information also changes significantly, making the positioning results inaccurate. [Means for solving the problem]

[0005] An embodiment of the present invention provides a method for positioning a device using signal direction, the method comprising: A step in which the positioning target device transmits to the base station a signal capable of measuring an angle, the signal including heartbeat data with the positioning target device ID attached thereto and a sine wave having a predetermined time length or a modulated wave having a known digital sequence; A base station including a signal arrival angle AOA calculation module and an antenna array required for AOA measurement calculates a signal arrival angle based on the angle-measurable signal, and sends the signal arrival angle to a positioning server; The positioning server calculates the position of the device to be positioned based on the signal arrival angle.

DETAILED DESCRIPTION OF THE INVENTION

[0012] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will further describe the embodiments of the present invention with reference to the accompanying drawings, wherein the exemplary embodiments of the present invention and the description thereof are for interpreting the present invention but are not intended to limit the present invention.

[0013] The acquisition, storage, use, and processing of data in the technical solution of this application shall all comply with the relevant provisions of national laws and regulations.

[0014] In view of the problems existing in the prior art described above, the present invention proposes a system for locating a device using signal direction. As shown in Fig. 1, the system includes a device to be located, a base station, and a positioning server. Here, the device to be located may be an electronic shelf label (ESL) (using 2.4G as shown in Fig. 1), a shopping cart in a supermarket (not shown in Fig. 1), or a person shopping (not shown in Fig. 1; the position of the person is determined by a mobile terminal carried by the person). The base station is, in other words, the AP shown in Fig. 1. The above-mentioned positioning target device, base station and positioning server are for realizing a method for positioning a device using signal direction. As shown in Figure 2, the method includes the following steps:

[0015] In step 201, the device to be positioned transmits to the base station a signal capable of measuring an angle, the signal including heartbeat data with the device ID attached and a sine wave having a predetermined time length or a modulated wave having a known digital sequence.

[0016] In step 202, a base station including a signal arrival angle AOA calculation module and an antenna array required for AOA measurement calculates the signal arrival angle based on the angle-measurable signal, and transmits the signal arrival angle to a positioning server (via the electronic shelf label network ESLW).

[0017] In step 203, the positioning server calculates the position of the device to be positioned based on the signal arrival angle.

[0018] Specifically, the heartbeat data is assigned the ID of the device to be positioned, making it easier to apply in the future. As shown in Figure 1, the AP includes a module (APcomm, hereinafter represented by an electronic shelf label ESL) that communicates with the device to be positioned and an additional 2.4G AOA (Arrival of Angle) module required for positioning. Note that an AP used separately for positioning includes only an AOA module but does not include a communication module. Some APs have both communication and positioning functions, while others only have an AOA module for positioning. This is merely an explanation of the options.

[0019] The location server is responsible for the positioning algorithms, including the electronic shelf label positioning algorithms and the positioning algorithms for people, shopping carts, etc.

[0020] Since the coverage area of ​​the module responsible for communicating with the electronic shelf label in the AP is larger than the measurement area of ​​the AOA received signal, it is necessary to install additional base stations that perform AOA measurements in several locations, as shown in Figure 3.

[0021] Here, stores may be advised to install APs with communication capabilities or APs with only positioning capabilities every 10 meters. However, regardless of the AP type, an AOA module must be installed. The positioning accuracy is approximately 1 meter. The AP is responsible for measuring the angle of the electronic shelf label signal, and the location server performs calculations on the positioning results. Alternatively, the AP may only be responsible for acquiring the original signal, and the location server may perform calculations on the angle and positioning results. This solution may also provide positioning functions for shopping carts and people.

[0022] 4 is a schematic diagram of the main circuit frame of the base station. In one embodiment, the base station includes RF circuits necessary for performing traffic data communication with the electronic shelf labels.

[0023] The above method is The method further includes a step in which the base station performs traffic communication with the positioning target device by using the RF circuit, and receives the heartbeat data and a sine wave or modulated wave from the positioning target device within its coverage area.

[0024] That is, the base station includes an antenna array necessary for angular positioning. The base station communicates traffic with the positioning target device using the RF circuit, and as shown in FIG. 4, the base station may have multiple RF circuits.

[0025] In an embodiment of the present invention, as shown in FIG. 1, the system further includes a map server, which controls the overall positioning process, map management, and APPs on the map, i.e., collects the results of calculations performed by the positioning server and maps them, and provides more flexible APP interfaces to higher-level APPs.

[0026] Specifically, as shown in FIG. 5, the method further includes the following steps:

[0027] In step 501, the position of the device to be positioned is transmitted to a map server, and the map server displays the position of the device to be positioned on a map.

[0028] In an embodiment of the present invention, as shown in FIG. 1, the system further includes an anchor (2.4G may be used), which is attached to the top of a shelf and transmits an AOA signal. Since the anchor is placed in a good position, the AP can perform more accurate positioning relative to the anchor. Further association between the anchor and the electronic shelf label may then be performed by a neighborhood learning method (a known positioning method). Thus, the position of the electronic shelf label can be obtained.

[0029] Specifically, as shown in FIG. 6, the method further includes the following steps:

[0030] In step 601, an anchor with a fixed and known location transmits an angle-measurable signal that is transmitted by a base station to a positioning server.

[0031] In step 602, the positioning server calibrates the attitude of the antenna array at the base station based on the signal angles of arrival of anchors of known location.

[0032] In step 603, the positioning server determines the location of the positioning target device having a neighbor relationship with the anchor by a neighbor positioning method based on the angle-measurable signal.

[0033] As described above, by calibrating the attitude of the antenna array at the base station, the accuracy of the attitude of the antenna array at the base station can be further improved, which in turn can further improve the accuracy of the coordinate system subsequently established based on the attitude of the positioning server and the base station.

[0034] 7, in the embodiment of the present invention, the positioning server calculates the position of the positioning target device based on the signal arrival angle in step 203. This step 203 includes the following steps:

[0035] In step 701, a coordinate system is established based on the positioning server and the attitude of the base station.

[0036] In step 702, a position simultaneous equation is constructed based on the signal arrival angle and the coordinate system.

[0037] In step 703, a solution is found from the simultaneous position equations to obtain the position of the device to be positioned.

[0038] Specifically, the basic principle of the system using 2.4G signals to perform AOA positioning of electronic shelf labels is as follows:

[0039] As shown in FIG. 8, a base station measures the signal strength and signal direction angle of an electronic shelf label, and then combines the signal strength and direction angle of the electronic shelf labels simultaneously received by multiple base stations to determine the location of some electronic shelf labels.

[0040] A single base station can measure the direction of a given electronic shelf label and map it to a single line in space. However, this line has a certain degree of error. Multiple lines corresponding to multiple base stations may have their own errors, but in theory they will intersect at a single point, and in practice they may intersect within a small area, or the one with the smallest error may intersect at a certain point in space.

[0041] The equations for a line in space are c1=a1x+b1y, c2=a2x+b2z.

[0042] For a given AP, its specific position in space is AP1(x1,y1,z1),AP1(x2,y2,z2),AP3(x3,y3,z3). From the measurement results, the following simultaneous equations can be constructed:

[0043]

number

[0044] The average of these solutions for x corresponds to the solution for x with the smallest error. When that x is reintroduced into the simultaneous equations, multiple solutions for y and z are obtained. Similarly, the average of these multiple solutions for y and z corresponds to the solutions for y and z with the smallest error. The final average values ​​of x, y, and z do not necessarily satisfy each equation, but each corresponds to the solution with the smallest error.

[0045] Regarding how the above linear simultaneous equations based on the base station measurements are constructed, the following will be explained by taking the AOA measurements by the base station.

[0046] The base station is equipped with an antenna array required for AOA measurement, and a separate 2.4GHz RF chip (i.e., a signal arrival angle calculation module) is added for AOA measurement. The design rules for the antenna array must comply with the requirements of the AOA algorithm. In principle, the transmission paths between the antennas in the antenna array and the main chip are completely identical, and the spatial distances between the antennas are completely equal. Examples of antenna arrays are shown in Figures 9 and 10. The multiple antennas are symmetrically arranged and have a circular or rectangular shape. It is sufficient to determine that the distance between adjacent antennas is half the wavelength of the 2.4GHz RF signal.

[0047] The base station controls the AOA measuring chip to receive the heartbeat signal of the ESL (the heartbeat signal is the signal capable of measuring the angle) and output the angle result. At the same time, the base station may also control the communication module to communicate with the ESL. At the same time, the AOA measuring chip will measure the signal.

[0048] As shown in Figure 11, the angle A1pha in the xy plane and the angle Beta in the xz plane are returned as the results of the AOA measurement. The slope of the line in the xy plane can be obtained based on A1pha, and the slope of the xz plane can be obtained based on Beta, and thus the above equation can be obtained accordingly. From the results of multiple APs, a corresponding simultaneous equation can be obtained. Taking AP1 as an example,

[0051] Finally, the electronic shelf tag is assigned to the shelf it belongs to based on the nearest shelf on the map of the positioning results.

[0052] Electronic shelf labels whose precise locations can be obtained may be located in the upper areas of the shelves and within direct line of sight of the base station.

[0053] Other electronic shelf labels located in lower shelf areas only have a relationship with the base station in which the signal is reflected or refracted multiple times, and it is difficult to obtain accurate positioning results for them using the angle measurement method. These electronic shelf labels can be further positioned according to the neighbor relationship (using the neighbor relationship positioning method in the prior art).

[0054] In an embodiment of the present invention, the AOA requires a sinusoidal signal with a certain duration. This signal may be added after the heartbeat signal of the electronic shelf label, as shown in Figure 12. The base station may individually designate the electronic shelf label, and a signal with such characteristics may be provided as the response signal of the electronic shelf label.

[0055] The heartbeat signal is a signal that is continuously received by all base stations. As described above, the electronic shelf label periodically reports the heartbeat, the base station continuously receives the heartbeat of the electronic shelf label, and the base station has its own positioning chip to process the signal, so no additional system-level processes are required in the positioning process. The positioning chip in the base station calculates and obtains the angle of a certain electronic shelf label, and then transmits the data to the positioning server. The positioning server can then construct a system of equations to find the solution.

[0056] Specifically, as shown in FIG. 13, before the positioning target device transmits an angle measurement signal to the base station, the method may further include the following steps:

[0057] In step 1301, the positioning server transmits an inquiry signal to the positioning target device via the base station.

[0058] The step of the base station calculating the signal arrival angle based on the angle-measurable signal includes the following steps:

[0059] Step 1302 includes the steps of the base station switching its frequency to a frequency of the inquiry signal, receiving a sine wave having a predetermined time length or a modulated wave having a known digital sequence, and calculating the signal arrival angle based on the sine wave or modulated wave.

[0060] Specifically, for a shelf label that has not received a heartbeat signal for a long period of time, the positioning server issues an inquiry to that shelf label, and the shelf label replies on the inquiry channel with a special ACK that meets the format shown in Figure 14. Multiple base stations can then individually query that shelf label and measure its signal. The measurement results are sent to the positioning server, which then performs calculations to obtain the positioning results. The communications subplate in the base station is responsible for querying the shelf label and receiving the ACK. At the same time, the positioning subplate, under signal control by the main plate, receives a sine wave or modulated wave at the specified query frequency point and determines the angle, referring to the switching frequency.

[0061] Interrogation of signals from multiple base stations will have a time lag, but interrogation of the positioning of electronic shelf labels that are stationary the majority of the time is still applicable.

[0062] In an embodiment of the present invention, once the trailing sine wave signal increases due to the shelf label heartbeat, a similar transmitting circuit to the shelf label may be added to the cart-positioned device or other device moving within the store, and the AP determines the actual location of the cart in the store based on the directional angle of the shelf label heartbeat signal received by the AP.

[0063] The cart transmits periodically according to the AOA signal that the AP can receive. The AP then performs positioning of the cart. Because the cart is located low, the signal that reaches the AP is the result of multiple path signals superimposed, and it is expected that there will be a large error.

[0064] Similarly, if a person walking inside a store turns on the Bluetooth function in the app on their mobile phone, their position can be determined using the AP's AOA, but it can be predicted that there will be a large error.

[0065] In one embodiment, the step of calculating the position of the positioning target device based on the signal arrival angle by the positioning server includes: a positioning server receiving signal arrival angles obtained by measuring the same positioning target device from one or more base stations during a time window having a predetermined time length; The positioning server calculates the position of the device to be positioned based on the signal arrival angles measured by the one or more base stations.

[0066] That is, the embodiment of the present invention can support calculating the position of the target device based on multiple signal arrival angles of the same target device measured by multiple base stations, thereby achieving the objective of enabling accurate measurement. An embodiment of the present invention further provides a computer device, the computer device including: a memory; a processor; and a computer program stored in the memory and executable by the processor, the computer program, when executed by the processor, realizing the method for positioning a device using signal directions as described above.

[0067] An embodiment of the present invention further provides a computer-readable storage medium, which stores a computer program, and when the computer program is executed by a processor, realizes the method for locating a device using signal direction described above.

[0068] An embodiment of the present invention further provides a computer program product, the computer program product including a computer program, which, when executed by a processor, implements the method for positioning a device using signal direction as described above.

[0069] In an embodiment of the present invention, electronic shelf labels communicate with and measure each other to determine their neighbor relationships. Furthermore, compared to conventional technologies that use additional IBeacons to perform positioning on electronic shelf labels or to enable real-time positioning of people, the present invention allows a device to be positioned to transmit an angle-measurable signal, including heartbeat data and a sine wave with a predetermined duration, to a base station. The base station, which includes a signal arrival angle calculation module and an antenna array required for AOA measurement, calculates the signal arrival angle based on the angle-measurable signal and transmits the signal arrival angle to a positioning server. The positioning server then calculates the location of the device to be positioned based on the signal arrival angle, thereby improving the accuracy of positioning for electronic shelf labels and reducing the complexity of the electronic shelf label positioning system. This positioning solution provides reliable positioning results for shelf labels within the direct line of sight of the AOA module, but not for shelf labels outside the direct line of sight. For those shelf tags that are not directly visible, a more accurate positioning result can be obtained by using a neighborhood learning method depending on the neighborhood relationship with the shelf tag with high reliability.
