detailed description

In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

The embodiments of the present application can be applied to indoor positioning scenarios. For indoor environments such as shopping malls and supermarkets, auxiliary indoor positioning can be performed based on existing equipment.

Taking supermarkets as an example, in current retail stores such as supermarkets, Electronic Shelf Labels (ESL) are often used to display the prices of retail goods and other information. This application can take advantage of the existing ESL system capabilities to reduce the equipment investment and maintenance investment for store positioning capacity building. The ESL broadcasts the beacon (Beacon) signal, which does not generate additional ESL management burden. Afterwards, indoor positioning can be performed based on the beacon signal broadcast by ESL to improve the accuracy of indoor positioning.

In the embodiment of this application, the electronic price tag ESL or other similar electronic devices can increase the Beacon signal source function, and the Beacon signal can be broadcast and sent wirelessly, such as through Bluetooth (bluetooth), radio frequency (Radio Frequency, RF), Zigbee ( ZigBee), wireless fidelity (WIreless-Fidelity, WI-FI) and other wireless methods to achieve signal transmission. Wherein, the electronic price tag ESL can be an active ESL or a passive ESL.

Referring to FIG. 1 , it shows a schematic diagram of an indoor positioning scenario according to an embodiment of the present application.

In the indoor scene, the Beacon signal is sent through the electronic price tag of the shelf, and the Beacon signal sent by a random number of electronic price tags can be received through various terminal devices, and the signal data of each Beacon signal can be uploaded to the server, so that based on the signal data Perform indoor positioning.

Among them, the electronic price tag ESL compatible with the beacon function can be deployed and broadcast.

The existing electronic price tag ESL can be upgraded to make it compatible with the beacon function, that is, the signal source function of the Beacon signal can be set for the electronic price tag ESL, and the electronic price tag ESL can be used as a signal source to broadcast the Beacon signal. Therefore, indoor positioning is performed based on the Beacon signal broadcast by each electronic price tag ESL.

Among them, the electronic price tag ESL is randomly distributed in the indoor environment, and the random distribution can be understood as this positioning method does not limit the placement of the electronic price tag ESL, but is determined based on the layout of indoor shelves and commodities. In order to prevent interference caused by too many Beacon signals, deployment and broadcast settings can be based on positioning accuracy requirements and Beacon signals, as shown in Figure 2:

Step 202, determine the price tag identification and location information of the electronic price tag, and generate a corresponding target list.

Electronic price tags ESL compatible with beacon functions can be deployed in stores and other indoor environments, and the location information and price tag identification of each electronic price tag ESL can be determined. The location information may be expressed in various forms such as longitude and latitude information, coordinate information, and the like. Taking the supermarket as an example, the product information is displayed on the shelf through the electronic price tag ESL. Among them, the commodities on the shelves of the supermarket are usually placed according to the regulations, and the commodity information can be displayed through the electronic price tag ESL, so the position information of each electronic price tag deployment can be determined, and the position of each electronic price tag can be recorded in the target list information. Among them, the price tag identification is the unique identification of the electronic price tag, which is used to uniquely determine an electronic price tag. It can be a unique string assigned to the electronic price tag, or it can be the MAC (Media Access Control, media access) of the electronic price tag. control layer) address, etc.

In some scenarios, the electronic price tag is used to display the product information of the product object, so the corresponding information can be recorded based on the product object in the target list, such as the minimum stock keeping unit (Stock keeping Unit, SKU) of the product object as the product identification , or other product identifiers. And record the product information corresponding to the product in the target list, such as the name, etc., and also record the device identification and location information of the electronic price tag. The embodiment of the present application does not limit the manner in which the electronic price tag is recorded in the target list, and may be determined based on actual applications. Wherein, the target list includes at least the device identification and location information of each electronic price tag.

Step 204, randomly assigning an offset to the electronic price tag, and setting a broadcast start time according to the offset.

After completing the deployment and recording of electronic price tags, in order to prevent interference caused by too many Beacon signals, a random broadcast time can be set for each electronic price tag to make the broadcast time slot random. Among them, a random offset can be configured for the electronic price tag, and the random offset can be set as a random number, taking a value between 0-100 seconds. Among them, in order to facilitate the management of the electronic price tag ESL, an electronic price tag management platform can be set up to randomly assign a random offset to the electronic price tag through the ESL registration system as the offset of the ESL's own time system. The time system may correspond to a reference broadcast time point, such as 0:00 or other designated time points, so that the start time of the electronic price tag broadcast is set by the reference broadcast time point and the offset, and its start broadcast is randomized point in time. Therefore, multiple electronic price labels ESLs in the same area may have different broadcast start times.

Step 206, based on the deployment information and positioning accuracy information of the electronic price tag, set the broadcast time interval of the electronic price tag, so as to perform indoor positioning based on the broadcasted beacon signal.

For the broadcast frequency of the electronic price tag ESL, it can be set based on the positioning accuracy requirements. Among them, under the condition of real-time requirements, the number of Beacon signals collected within the effective transmission area of Beacon signals is related to the deployment density of electronic price tags ESL, the effective transmission area of Beacon signals, broadcast time slots, and the probability that Beacon signals are detected by terminal equipment scanning . The effective transmission area of the Beacon signal is based on the effective transmission distance of the Beacon signal. The broadcast frequency of the Beacon signal can be determined based on the broadcast time slot. Therefore, setting the broadcast frequency reasonably under the premise of ensuring the positioning accuracy can reduce the power consumption of the electronic price tag ESL. For passive ESL, reducing power consumption can also reduce the loss of service life.

Wherein, the deployment information is information related to deploying the electronic price tag ESL in the indoor environment. Deployment information includes: deployment density information, effective signal transmission area and scanning probability. The deployment density information is the deployment density of the electronic price tag ESL in the indoor environment. The effective signal transmission area is the effective transmission area of the Beacon signal of the electronic price tag ESL, that is, the Beacon signal of the electronic price tag ESL can be received within the transmission area. The scanning probability is the probability that the Beacon signal of the electronic price label ESL is scanned. The positioning accuracy information is accuracy requirement information for indoor positioning. The positioning accuracy information may include the number of positioning signals, where the number of positioning signals is the number of Beacon signals collected for indoor positioning. The positioning accuracy information may also include real-time demand information for positioning, etc., which may be determined according to actual positioning requirements.

In an optional embodiment, setting the broadcast time interval of the electronic price tag based on the deployment information and positioning accuracy information of the electronic price tag includes: determining the deployment information of the electronic price tag, and the deployment information includes: Deployment density information, effective signal transmission area and scanning probability; determine the positioning accuracy information of indoor positioning; calculate the broadcast frequency of the electronic price tag according to the deployment information and positioning accuracy information of the electronic price tag; set the broadcast frequency according to the The broadcast time interval of the electronic price tag.

In an example, assume that the deployment density of ESLs is, for example, 10,000 ESLs/1,000 square meters of store customer area, and the deployment density of ESLs is ESL_Density=10/square meter. Positioning accuracy requirement: Req_Resolution=2 meters. The effective transmission distance of the Beacon signal of the electronic price tag ESL is Sig_Effect_Distance=10 meters. Beacon signal effective transmission area: Sig_Effect_Area = 100 square meters. To achieve positioning accuracy, the number of Beacon signals that need to be collected in the effective transmission area of Beacon signals per unit time: Req_Effect_Beacon_Num=5, that is, the collected Beacon signals must be no less than 5. Beacon signal DA scanning discovery probability: Scan_Probability=0.2. Real-time positioning requirements: Req_Loc_Frequency=1 time/second.

Under the condition of real-time requirements, the number of Beacon signals within the effective transmission area of Beacon signals satisfies: ESL_Density (ESL deployment density) * Sig_Effect_Area (Beacon signal effective transmission area) * Frequency_Beacon (broadcast time slot) * Scan_Probability (Beacon signal DA scanning discovery probability )=Req_Effect_Beacon_Num (Number of Beacon signals to be collected)*Req_LLoc_Frequency (requirements for real-time positioning). That is, 10*100*Frequency_Beacon*0.2=5*1. Corresponding Frequency_Beacon = 0.025 times/second. Therefore, it is determined that the ESL compatible with the beacon function needs to set the time interval of the Beacon broadcast signal: 40 seconds/time.

The broadcast time interval of the electronic price tag can be set based on the time interval, so as to determine the transmission interval of each Beacon signal. Through the broadcast frequency calculation, the broadcast frequency matching the positioning accuracy requirements is obtained, and the balance between the positioning accuracy and the broadcast function’s impact on the ESL life of the electronic price tag is realized, and the positioning accuracy and positioning Beacon signal broadcast energy efficiency and Bluetooth channel occupancy are balanced to meet the application requirements. indoor positioning capability. And it can realize the electronic price tag ESL compatible indoor positioning function at a relatively small cost. In addition, indoor positioning can be performed based on the electronic price tag, and the positioning accuracy can be improved.

After completing the above settings, indoor positioning can be performed based on the beacon signal broadcast by the electronic price tag in supermarkets, shopping malls and other indoor environments.

Wherein, the terminal device for indoor positioning may be various terminal devices, such as a handheld device (Digital Assistant, DA), a tablet computer, and a mobile phone, and may be selected based on requirements and applications. Among them, the handheld device DA can be used by employees with display and input components when performing operations such as putting on shelves, sorting, replenishing, packing, and moving warehouses for corresponding objects in retail, pharmaceutical, and logistics industries. Electronic equipment, equipped with memory, CPU, screen and keys or keyboard, capable of wireless data transmission and processing, equipped with batteries, can be used mobile. The mobile phone can be a mobile phone used by the user. For example, the user's mobile phone is installed with an application program of a supermarket or a shopping mall. After obtaining the user's authorization, functions such as scanning and positioning and product search can be enabled. Another example is that a tablet computer or other terminal equipment can be installed on a shopping cart in a supermarket, so that the user can locate or search for the corresponding product object if necessary during the shopping process. In each of the above methods, after the positioning function is enabled, the terminal used by the user can scan the beacon signals of the surrounding electronic price tags, and locate his own position through the signal data of multiple beacon signals. It is also possible to determine the discharge location of the product to be searched based on the demand, and determine the route based on its own location information and the discharge location of the product, so that it is convenient to quickly find the corresponding product for shopping, distribution and other processing.

Referring to FIG. 3 , it shows an interactive schematic diagram of an indoor positioning method according to an embodiment of the present application.

Step 302, the terminal device scans the beacon signal broadcast by the electronic price tag, and receives signal data of multiple beacon signals.

When necessary, the terminal device can turn on the scanning function to scan the beacon signal broadcast by the electronic price tag, so as to receive the signal data of multiple beacon signals in a unit time. Signal data includes price tag identification and positioning related information. Wherein, the signal identifier may be a unique identifier of the electronic price tag, such as a MAC address. The location-related information may be information related to location, such as signal strength, signal fingerprint, and other information. For example, Bluetooth positioning can be Bluetooth fingerprints, and WI-FI positioning can be WI-FI fingerprints. Wherein, the signal strength may be acquired when a beacon signal is scanned.

In other scenarios, such as when a user is shopping in a supermarket, and sometimes needs certain product objects, the target product object can be queried through a mobile phone or a terminal device on a shopping cart, etc., and the keyword of the target product object can be input to open In the case of the positioning function, the terminal device can scan the beacon signal to locate its own location, check the placement location of the target product object, and plan the path from the location to the product discharge location, which is convenient for quick purchase of product objects .

In other scenarios, for staff in supermarkets, shopping malls, etc., terminal devices such as handheld devices can be used, and the terminal device can enable the positioning function to scan beacon information to locate their own location. Operations such as point confirmation and location reporting can be performed based on the positioning location, so that it is convenient to confirm the location of the relevant user. Therefore, when the designated location is reached, the scanning function can be activated to receive the beacon signals broadcast by multiple electronic price tags through scanning. In addition, combined with the location information of the staff, it is also possible to manage the staff, confirm whether the location is correct, judge whether there is any illegal operation, etc., and correspondingly generate a positioning report result, which is displayed on the user's terminal, and there are violations in the supermarket Such as equipment loss, loss of goods, etc., can also be verified based on location information to improve management efficiency. For example, the product objects in the supermarket need to be maintained by relevant staff, and expired products are removed from the shelves. Once expired products appear, the relevant processing personnel can be checked based on the location information.

Step 304, the terminal device uploads the signal data of the plurality of beacon signals to the server.

The received signal data of multiple beacon signals may be sent to the server.

In step 306, the server separately queries the location information corresponding to the plurality of beacon signals through the target list.

After obtaining the signal data of multiple beacon signals, the server can obtain the price tag identification and positioning related information, and then query the target list according to each price tag identification. Wherein, the commodity object corresponding to the price tag identifier can be queried in the target list, and then the location information of the commodity object can be queried. Among them, generally in supermarkets and other environments, product objects will be displayed according to certain rules, and a target list will be generated accordingly to record the product information, location of the product object and the price tag information of the associated electronic price tag. Therefore, the price tag identification based on the electronic price tag can also be corresponding to the corresponding commodity object, and then the position of the electronic price tag is determined based on the position of the commodity object. And in this process, electronic price tags can also be filtered based on multiple location information. If the position corresponding to some electronic price tags is far away from the position corresponding to other electronic price tags, it can be considered as noise data , ignore the electronic price tag.

Therefore, when setting the broadcast time slot of the electronic price tag, you can set a reasonable number. By scanning an appropriate number of Beacon information, you can avoid too much electromagnetic interference on site due to too many quantities, and will not cause excessive electromagnetic interference due to too few quantities. Inaccurate positioning. Moreover, some Beacon signals corresponding to the electronic price tags do not match the list, which can be regarded as noise and discarded to ensure the accuracy of the data.

In step 308, the server calculates the location information of the terminal device according to the location information and positioning related information corresponding to the plurality of beacon signals.

After the location information of the electronic price tag corresponding to each beacon signal is acquired, the location information of the terminal device can be determined based on the location information and location-related information.

When the location-related information is the signal strength of the beacon signal, the location information of the terminal device may be determined based on the signal strength of the beacon signal and location information. For example, the position and distance of the target can be determined based on the triangulation method, using the principles of triangular geometry. The distance to the corresponding electronic price tag can be determined based on the signal strength of the beacon signal, and the center position can be determined based on at least three electronic price tags as the location information of the terminal device. For example, after determining the beacon signals of the three electronic price tags, the center position can be determined based on the triangulation method, so as to obtain the position information of the terminal. For another example, after determining the beacon signals of 4 or more electronic price tags, the position can be calculated based on information such as the coordinates of each electronic price tag and the received signal strength.

In some other scenarios, the location-related information may be fingerprint information, such as Bluetooth fingerprint data, WI-FI fingerprint data, and the like. Among them, the wireless fingerprint data can be understood as a location fingerprint, which refers to the connection between the location in the actual environment and a certain "fingerprint", and a location corresponds to a unique fingerprint. The fingerprint database of each location can be collected and established based on the corresponding wireless method in advance. Therefore, the fingerprint information corresponding to the beacon signal of the electronic price tag can be measured, and the fingerprint information is matched with the wireless fingerprint data corresponding to the fingerprint database to determine the matched position information, and then determine the position information of the terminal device.

The above are only two examples of positioning, and positioning can be performed according to requirements in actual processing.

Step 310, determine a positioning result according to the location information of the terminal device.

The location information of the terminal device can be used as the positioning result. In other scenarios, the product information of the product object within the predetermined range can also be searched based on the location information. The information is the center of the circle, and the product object within the predetermined range returns the product information of the product object together with the positioning result, so that it is easy to understand the product layout around the current location. Therefore, for the staff of the supermarket, they can conveniently determine their location and surrounding commodity objects, so as to facilitate the putting and adjustment of commodity objects. And if the user who uses positioning is a shopping user, it can determine which commodity objects are around, which is convenient for selection.

In the above embodiments, the positioning beacon signal may be sent along with the query request. Therefore, the location information of the queried target commodity object can be determined based on the target list, and then based on the location information of the positioned terminal device, it can be based on the path from the positioned location to the location of the target commodity object. Therefore, the staff of the supermarket can quickly determine the position and path of the commodity object to be placed. For shopping users, you can quickly find the location of the product object to be purchased and the path to it, improving the shopping experience.

Step 312, sending the positioning result to the terminal device.

Step 314, display the positioning result on the interface.

At least one of the following positioning results may be displayed on the interface: displaying the positioned location information on the interface; displaying commodity information within a predetermined range of the location information on the interface; displaying path information to the target commodity object on the interface. The display mode of the specific positioning result may be determined according to requirements.

In summary, by searching the target list and the position information of the electronic price tag corresponding to the commodity object in the database, the actual spatial position information of the electronic price tag ESL is obtained, which is used for the positioning calculation of the positioning engine. Guarantees the availability of randomized low frequency broadcast Beacon signals.

On the basis of the above-mentioned embodiments, the embodiment of the present application provides an indoor positioning method, which can conveniently inquire about the location and the arrival route of the target product object.

Referring to FIG. 4A , it shows an interactive schematic diagram of an indoor positioning method according to an embodiment of the present application.

Step 402, receiving the query keywords, and receiving beacon signals broadcast by multiple electronic price tags by scanning.

In the case of inquiring about the target commodity object, the query function of the corresponding application program can be started, such as the user's supermarket application program, the application program used by the staff to distribute goods, and the like. The keyword can be determined based on the commodity object to be queried, and the corresponding keyword can be input and searched. After the terminal device receives the keyword, it can start the scanning function to receive the beacon signals broadcast by multiple electronic price tags through scanning.

Step 404, the terminal device generates a query request by using the plurality of beacon signals and keywords.

Step 406, the terminal device sends the query request to the server.

In a scenario as shown in FIG. 4B , the supermarket can install a terminal device with a display such as a tablet computer on the armrest crossbar of a transportation device such as a shopping cart, a sorting cart for distribution, and a replenishment cart. During the shopping process of the user or the process of arranging the commodity objects, the user can input the keyword of the target commodity object to be queried through the terminal device. Another example is that when the staff sorts out the commodity objects, they can scan the corresponding target commodity objects through the terminal device to obtain keywords, such as the barcode identification of the target commodity object, or other commodity logos, commodity names, etc. as keywords. Wherein, in order to improve search efficiency, corresponding query conditions may also be provided, which is not limited in this embodiment of the present application.

A query request is generated based on the scanned multiple beacon signals and keywords, and the terminal device sends the query request to the server to query the commodity object.

In step 408, the server searches for the matched target product object and the location information of the target product object based on the keyword. Wherein, at least one target commodity object and its location information that can be retrieved can also be filtered based on some query conditions.

In step 410, the server separately queries the location information corresponding to the plurality of beacon signals through the target list.

In step 412, the server calculates the location information of the terminal device according to the location information and positioning related information corresponding to the plurality of beacon signals.

The server may determine the location information of the terminal device based on the signal data of multiple beacon signals, in a manner similar to that of the above-mentioned embodiment, so details are not repeated here.

Step 414, the server determines the route information to the target commodity object according to the location information of the terminal device and the location information of the target commodity object.

Based on the location information of the terminal device and the location information of the target commodity object, a path from the location of the terminal device to the location of the target commodity object can be calculated to obtain route information to the target commodity object.

Step 416, the server generates query results according to the commodity information and route information of the target commodity object.

Wherein, the query result can be regarded as a positioning result. The location information of the terminal device and the location information of the target commodity object can also be added to the query result.

Step 418, the server sends the query result to the terminal device.

Step 420, the terminal device displays the commodity information and route information of the target commodity object on the interface. As shown in FIG. 4B, product information such as the name of the target product object can be displayed, and route information to the product object can also be displayed.

Therefore, when the user uses it, the path to the target commodity object can be quickly determined, and the efficiency of querying the target commodity object can be improved.

In some examples, a device similar to an electronic price tag that can emit wireless signals for positioning can also be installed on some designated commodity objects, so that the beacon signal of the designated commodity object can be received through the above-mentioned method, and the location of the designated commodity object can be determined. In some other examples, positioning devices similar to terminal equipment are installed on some designated commodity objects, which have the ability to receive signals and interact with the server, so that they can receive beacon signals from multiple electronic price tags around them and upload them to The server performs positioning, so that the location change and real-time location of the specified commodity object can be obtained. The designated product object can be set according to the requirement, such as the product object that needs to be managed, the high-value product object, etc., so as to improve the security of the product object and facilitate the management of the product object.

The embodiment of the present application also provides a location reporting method. Take the scene where the staff of the supermarket is replenishing and tallying the goods as an example. The staff can carry handheld devices, or terminal devices such as handheld devices are installed on the transport devices and basket devices used by the staff. Based on this terminal The device is positioned.

After detecting that the positioning condition is met, scan the beacon signal broadcast by the electronic price tag, and receive the signal data of multiple beacon signals. Wherein, the positioning condition is a condition for starting positioning, and the positioning condition includes that the dwell time exceeds a preset time, and/or, the reporting period is reached. After the positioning condition is met, the terminal device can be used to scan and receive the signal data of the beacon signal. Then, the signal data of multiple beacon signals and the terminal information of the terminal can be used as positioning reporting information and reported to the server. The server can separately query the location information corresponding to the plurality of beacon signals through the target list; calculate the location information of the terminal device according to the location information and positioning related information corresponding to the plurality of beacon signals, and based on the location information Determine the positioning result. Based on the positioning result of the terminal device, for example, the terminal information includes the terminal identification, etc., the server may record terminal information such as the terminal identification, positioning result, positioning time, etc. in the corresponding positioning record. Wherein, the positioning time may be the reporting time of the positioning reporting information.

Therefore, the information of each terminal and its reported positioning results and reporting time can be recorded on the server side. The staff can associate with the terminal device when using the terminal device, and end the association when the use is over, so that the association relationship can be determined. The positioning results reported within the usage time. In the management process, when a target event occurs in some areas, the staff at the location can be determined based on the positioning results, so as to determine the person in charge. Another example is when an expired product is checked or sold, the staff responsible for the deadline review can be determined based on the positioning result. As another example, when the product object is damaged, the staff who distribute, pick and inspect the goods can also be checked based on the positioning results to improve management efficiency.
