[0028] Example 1

[0029] Figure 1 This is a flowchart illustrating a method for determining a tracking target according to Embodiment 1 of the present invention. This embodiment is applicable to scenarios involving the location of at-risk individuals visiting indoor spaces. The method can be executed by a target determination device, which can be implemented in hardware and / or software and can be configured in an electronic device. Figure 1 As shown, the method includes:

[0030] S110. Obtain the location information of at least two user terminals through the analysis platform, and determine at least one user group based on the location information of each user terminal.

[0031] This solution can be executed by a target tracking analysis system, which may include an analysis platform, at least one user terminal, and pre-deployed positioning beacons in an indoor space. The user terminal may be a mobile phone, tablet, or other device equipped with a location application. The positioning beacon may be a beacon providing a reference position based on technologies such as infrared, Bluetooth, or ZigBee. The positioning beacon can periodically broadcast a device with its own unique identifier. The user terminal can communicate with the positioning beacon, receive the broadcast signal, and determine the strength value of the broadcast signal. The user terminal can transmit the received broadcast signal strength value to the analysis platform via the internet. Based on the broadcast signal strength value, the analysis platform can calculate the user terminal's location information and record the location time information for each location. The location information is determined based on the user terminal's location information and the location time information. The user terminal's location information and location time information can be in a one-to-one correspondence.

[0032] In this solution, optionally, the positioning information includes the location information of the user terminal and the positioning time information;

[0033] The step of determining at least one user group based on the location information of each user terminal includes:

[0034] Based on the location information and positioning time information of each user terminal, at least one user group is identified.

[0035] Understandably, the analysis platform can determine the location and distance between user terminals based on their location information. Based on the location time information, the platform can determine whether each user terminal is at the target location. If a user terminal is detected at the target location, the platform can also record the duration of that stay. Based on the location, distance, and stay time of each user terminal, the platform can determine whether the users holding these terminals meet the conditions for risk propagation. If the conditions are met, the user terminals that meet these conditions can be grouped together to search for and track the target once a reference target is identified within the group.

[0036] Based on the above scheme, determining the user group according to the location information and positioning time information of each user terminal includes:

[0037] If the location information of at least two user terminals meets the preset location conditions and the location time information meets the preset time conditions, then the at least two user terminals constitute a user group.

[0038] Specifically, the risk propagation conditions may include location conditions and time conditions. Location conditions may include the spatial coordinates of each user terminal being within a preset range, or the distance between user terminals being less than or equal to a preset distance threshold. Time conditions may include each user terminal maintaining a constant relative position for a preset duration within a certain error tolerance range. If the location information of at least two user terminals satisfies both the location condition and the time information, then these at least two user terminals are determined to be a user group.

[0039] The above scheme can group user terminals that meet the risk propagation conditions based on location information, so that the analysis platform can determine the tracking target according to the user group, which is conducive to achieving decentralized positioning.

[0040] S120. Send an identifier transmission and reception instruction to each user terminal in the user group, so that each user terminal sends the matching terminal identifier information and receives the terminal identifier information of other user terminals besides the user terminal itself.

[0041] After identifying a user group, the analysis platform can send identifier transmission and reception instructions to each user terminal within that group. Upon receiving the instructions, each user terminal can send its own identifier information and simultaneously receive the identifier information from other user terminals within the group, thus enabling the recording of identifiers within the user group.

[0042] S130. If the target user terminal is determined to be the reference target, the target terminal identification information recorded by the target user terminal is obtained, and the tracking target is determined based on the target terminal identification information.

[0043] The analysis platform can determine tracking targets based on the target user terminal identified as a reference target. The reference target can be a user terminal used by a user diagnosed with an infectious disease. Since user terminals record the identification information of each user terminal within the same user group, the analysis platform can determine the identification information of other user terminals within the user group based on the target terminal identification information recorded on the target user terminal. The analysis platform can use all user terminals matching the target terminal identification information as tracking targets, or it can determine the contact risk ranking based on information such as coexistence time and coexistence distance, and then determine the tracking targets based on the contact risk ranking.

[0044] This technical solution acquires the location information of at least two user terminals and determines at least one user group based on the location information of each user terminal. Then, it sends identification transmission and reception commands to each user terminal within the user group, enabling each user terminal to send matching terminal identification information and receive terminal identification information from all other user terminals except its own. If a target user terminal is determined as a reference target, the target terminal identification information recorded by the target user terminal is acquired, and the tracking target is determined based on the target terminal identification information. This technical solution solves the problems of poor positioning accuracy and low efficiency in indoor space target tracking, improving the efficiency of target determination while achieving accurate target positioning.

[0045] Example 2

[0046] Figure 2 This is a flowchart of a method for determining a tracking target according to Embodiment 2 of the present invention. This embodiment is a refinement based on the above embodiment. Figure 2 As shown, the method includes:

[0047] S210. Obtain the location information of at least two user terminals through the analysis platform, and determine at least one user group based on the location information of each user terminal.

[0048] In this solution, optionally, the target tracking analysis system also includes Bluetooth beacons pre-deployed in the indoor space; the Bluetooth beacons communicate with the user terminal via Bluetooth.

[0049] The acquisition of location information from at least two user terminals through the analysis platform includes:

[0050] The platform obtains time information and signal strength information received by the user terminal;

[0051] The platform analyzes signal strength information to determine the distance and direction of each user terminal relative to the Bluetooth beacon.

[0052] The platform analyzes distance, direction, and time information to determine the location information of each user terminal.

[0053] Understandably, the Bluetooth beacon can be a device that periodically broadcasts its own unique identifier via Bluetooth to provide reference location information for personnel positioning. User terminals can communicate with the Bluetooth beacon via Bluetooth, receive the broadcast signal, and determine the signal strength. User terminals can communicate with the analysis platform via the internet, sending the received Bluetooth beacon broadcast signal strength value to the platform. Based on the broadcast signal strength value, the analysis platform can calculate the distance and direction information of each user terminal relative to the Bluetooth beacon, and then determine the user terminal's location information based on this distance and direction information. Simultaneously, the analysis platform can record the positioning time information corresponding to each Bluetooth positioning. The positioning information is determined based on the user terminal's location information and positioning time information. The user terminal's location information and positioning time information can be in a one-to-one correspondence.

[0054] Intuitively, a user terminal equipped with a directional antenna network can achieve accurate directional positioning. To determine the direction of a signal, the receiver (angle of arrival, AoA) or transmitter (angle of departure, AoD) of the broadcast signal can have a permanently installed antenna mesh network, and the receiver can determine the direction of the signal transmission. Angle information can be determined by triangulation of one or more angles calculated in terms of AoA or AoD, and by measuring distance using RSSI (Received Signal Strength Indication), allowing position determination to be accurate to within centimeters. In enclosed spaces, AoA can be used for tracking, and AoD for navigation. In AoA-based applications, the transmitter can be a Bluetooth beacon with a single antenna, and multiple permanently installed receivers can be used to determine the direction of the received broadcast signal, where each receiver can be equipped with a complex antenna mesh network.

[0055] Regarding antenna mesh networks, the antenna mesh network of a user terminal can be a simple series of antennas arranged one after another, or it can be a more complex configuration in three-dimensional space to determine the horizontal and vertical angles and achieve more accurate directional positioning.

[0056] This invention can achieve accurate user terminal positioning, reduce positioning errors, and thus achieve more precise user group segmentation.

[0057] S220. The analysis platform sends identification transmission and reception instructions to each user terminal in the user group, so that each user terminal sends matching terminal identification information and receives terminal identification information from other user terminals besides its own.

[0058] Optionally, in this solution, the step of sending identifier transmission and reception instructions to each user terminal within the user group through the analysis platform, so that each user terminal sends matching terminal identifier information and receives terminal identifier information from other user terminals besides its own, includes:

[0059] The analysis platform sends identification transmission and reception instructions to each user terminal within the user group, enabling each user terminal to send matching signals and receive signals from other user terminals besides its own.

[0060] This scheme records the identification signals of each user terminal in the same user group by sending identification signals within the user group. This enables simple and convenient identification information recording, saves hardware resources, and achieves more comprehensive tracking target information recording.

[0061] S230. If the target user terminal is determined to be a reference target, an identifier upload instruction is sent to the target user terminal through the analysis platform so that the target user terminal uploads the target terminal identifier information to the tracking target analysis system.

[0062] To conserve hardware resources in the target tracking analysis system, if the target user terminal is identified as a reference target, the analysis platform can send an identifier upload message to the target user terminal, enabling the target user terminal to upload the target terminal identifier information recorded in the target user terminal to the target tracking analysis system.

[0063] By acquiring the target terminal identification information when the target user terminal is identified as the reference target, the target tracking and analysis system can avoid storing a large amount of identification information and analyzing large-scale data. It only needs to acquire the target terminal identification information of the target user terminal, which greatly saves the storage and computing resources of the target tracking and analysis system.

[0064] S240. The user terminal whose target terminal identification information matches is taken as the tracking target.

[0065] The analysis platform can track all user terminals that match the target terminal identification information as the tracking target to achieve reliable and effective risk control.

[0066] This technical solution acquires the location information of at least two user terminals and determines at least one user group based on the location information of each user terminal. Then, it sends identification transmission and reception commands to each user terminal within the user group, enabling each user terminal to send matching terminal identification information and receive terminal identification information from all other user terminals except its own. If a target user terminal is determined as a reference target, the target terminal identification information recorded by the target user terminal is acquired, and the tracking target is determined based on the target terminal identification information. This technical solution solves the problems of poor positioning accuracy and low efficiency in indoor space target tracking, improving the efficiency of target determination while achieving accurate target positioning.

[0070] The identifier transmission and reception instruction sending module 320 is used to send identifier transmission and reception instructions to each user terminal in the user group through the analysis platform, so that each user terminal sends matching terminal identifier information and receives terminal identifier information from other user terminals besides its own.

[0071] The target determination module 330 is used to obtain the target terminal identification information recorded by the target user terminal through the analysis platform if the target user terminal is determined to be a reference target, and to determine the tracking target based on the target terminal identification information.
