[0060] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0061] The following detailed description is an exemplary description, which is intended to provide further detailed description of the present invention. Unless otherwise specified, all technical terms used in the present invention have the same meaning as those generally understood by those skilled in the art to which the present invention belongs. The terms used in the present invention are only for describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present invention.

[0062] Before describing this embodiment, a brief description of the application scenario is given first. Figure 1 , the schematic diagram includes a first device 101, a second device 102, a star flash beacon 103 and a server 104. The first device 101 and the second device 102 are respectively connected to the server 104 for communication, and the star flash beacon 103 is set on the object or within a preset distance range of the object. The star flash beacon 103 is a wireless communication device for sending wireless signals to identify a specific location or provide key information.

[0063] Both the first device 101 and the second device 102 can track the item through the star flash beacon 103. The first device 101 can upload the target position information of the tracked item to the server 104, and then send it to the second device 102 via the server 104, or the second device 102 can upload the target position information of the tracked item to the server 104, and then send it to the first device 101 via the server 104.

[0064] In one embodiment, the first device 101 and the second device 102 can directly establish a communication connection with the Star Flash Beacon 103, wherein the communication protocol framework of the first device 101, the second device 102 and the Star Flash Beacon 103 can be constructed based on the Star Flash technology. Alternatively, the first device 101 and the second device 102 can also use an external transceiver to achieve communication with the Star Flash Beacon 103, wherein the communication protocol framework between the external transceiver and the Star Flash Beacon can be constructed based on the Star Flash technology, and the external transceiver can improve the compatibility of the tracking method of the item.

[0065] The communication protocol framework of Star Flash technology can be found in Figure 2 , which consists of three parts: Star Flash access layer, basic service layer and basic application layer.

[0066] The basic application layer provides protocol support for audio streaming services, video streaming services, data transmission services, etc., and formulates profiles for specific applications. The Spark Basic Service Layer provides a unified and complete functional interface for specific applications of the basic application layer, including functional units such as device discovery, service discovery, connection management, QoS management, security management, multi-domain coordination and measurement management. The control plane of the basic service layer establishes connections and configures transmission parameters. The data plane of the basic service layer performs data transmission and adaptation, and measures transmission quality. The Spark Access Layer provides a pipeline for air interface transmission for the basic service layer, supports the basic service layer functions and the QoS required for data transmission, and can carry deterministic synchronous data transmission or asynchronous data transmission. The Spark Access Layer provides two communication interfaces: SparkLinkbasic (SLB) and SparklinkLowEnergy (SLE). Among them, SLB adopts multiple technologies such as ultra-short frames, multi-point synchronization, two-way authentication, fast interference coordination, two-way authentication encryption, cross-layer scheduling optimization, etc., to support business scenarios with transmission requirements such as low latency, high reliability, precise synchronization, high concurrency and high security. SLE uses Polr channel coding to improve transmission reliability, reduce retransmission and save power consumption. It also supports a maximum transmission bandwidth of 4MHz, a maximum of 8PSK modulation, supports multi-reliable multicast, supports 4KHz short-delay interaction and other features. While ensuring transmission efficiency as much as possible, it fully considers energy-saving factors and is used to carry business scenarios with low power consumption demands. Both SLB and SLE are composed of a physical layer and a data link layer, and provide different transmission services for different business demands. The two complement each other and continue to evolve smoothly according to business needs. In this embodiment, since the application scenario is an indoor positioning scenario, and based on cost considerations, the Star Flash node provided in this embodiment preferably adopts an SLE communication interface.

[0067] The ranging accuracy of Star Flash technology can reach centimeter level, which is better than object tracking based on Bluetooth. In the process of tracking objects, the Star Flash beacon is used as the SLE client, and only needs to communicate with the first device 101 or the second device 102 when the ranging connection is in progress. When not connected, it is in a scanning state, with low power consumption and battery power supply. It can be placed near any object that needs to be tracked, and has the effect of low power consumption and high precision ranging.

[0068] In one embodiment, the server 104 may be two complete computing engines (processing cores) integrated on a multi-core processor, and may belong to two different single-core processors or two different multi-core processors. A multi-core processor refers to two or more complete computing engines integrated into one processor. Furthermore, the server 104 may also be other computer devices having the same or similar computing devices as the processor. Furthermore, the server 104 may be replaced by a server system, a computing platform or a server cluster including multiple servers.

[0069] On this basis, see Figure 3 The embodiment of the present invention provides a method for tracking an item, which is applied to a mobile device, and the method includes:

[0070] S301: Acquire multiple groups of historical movement information corresponding to a mobile device during multiple historical movement processes.

[0071] Among them, each set of historical movement information in the multiple sets of historical movement information includes historical device location information and corresponding historical distance information. The historical device location information can be determined by any one of GPS, RFID, Bluetooth, Star Flash technology, etc. The historical distance information is the historical distance information between the mobile device and the object under the historical device location information.

[0072] In one embodiment, a star flash beacon is configured on the object, or a star flash beacon is configured within a preset distance range of the object. The number of star flash beacons can be one or more. Figure 4 , before step S301, further comprising:

[0073] S401. Broadcast a configuration message to the Star Flash beacon.

[0074] The broadcast configuration message is used to instruct the Star Flash Beacon to send a connection request message to the mobile device. Specifically, the broadcast configuration message may include at least one of the mobile device's identifier, service information, and a connection request identifier.

[0075] Specifically, the premise for the Star Flash Beacon to receive the broadcast configuration message is that the Star Flash Beacon is in a listening state. After receiving the broadcast configuration message, the Star Flash Beacon will initiate a connection request message according to the content in the broadcast configuration message. The Star Flash Beacon sends a connection request message. The connection request message may include at least one or more of the Star Flash Beacon's identifier, target server information, connection parameters, security requirements, and service type.

[0076] S402: Establish a connection with the Star Flash Beacon according to the connection request message sent by the Star Flash Beacon.

[0077] In one embodiment, after the mobile device establishes a communication connection with the Star Flash beacon, see Figure 5 The specific steps of obtaining each set of historical movement information in step S402 include:

[0078] S3011. For each historical movement process, send an attribute configuration message to the Star Flash Beacon.

[0079] The attribute configuration message is used to instruct the Star Flash Beacon to send an attribute message to the mobile device. The attribute message is used to perform position measurement to obtain historical movement information. In this embodiment, the historical movement information may specifically be historical distance information.

[0080] The attribute message may be a SSAP (Signal Strength Access Point) message. The attribute message includes one or more of the following: Received Signal Strength Indication (RSSI), Reference Signal Receiving Power (RSRP), the difference between the sending time and receiving time of the signal, the arrival angle received by different receiving antennas of the Star Flash Beacon, the phase difference of the signal waveform received by different receiving antennas of the Star Flash Beacon, the phase difference of the signal transmitted by different antennas of the device received by the same antenna of the Star Flash Beacon, or the time difference, the round trip time difference (RTT) of the signal transmitted between the device and the Star Flash Beacon.

[0081] S3012. Perform position measurement according to the attribute message sent by the Star Flash Beacon to obtain each group of historical movement information.

[0082] In one embodiment, step S3012 further includes: smoothing the historical distance data according to the RSSI in the attribute data to reduce the impact of the interfered historical distance data on the position tracking and improve the position tracking accuracy.

[0083] S302: Acquire current device location information of the mobile device.

[0084] Among them, the current device location information can be determined by any one of GPS, RFID, Bluetooth, star flash technology, etc.

[0085] S303: Determine target position information of the object relative to the mobile device based on multiple sets of historical movement information and current device position information.

[0086] In one embodiment, the target position information includes object position information and current distance information. Figure 6 , step S303 includes:

[0087] S3031. Determine the location information of the item based on multiple sets of historical movement information.

[0088] In one embodiment, the object location information is determined based on three sets of historical movement information among the multiple sets of historical movement information.

[0089] See also Figure 7 The following is an example of the calculation process of the item location information. When the three sets of historical movement information of the mobile device include: historical movement information A, historical movement information B and historical movement information C, the item location information can be calculated according to the three-point positioning. The calculation formula is as follows:

[0090]

[0091] Among them, (x A ,y A ) is the historical device location information of historical mobile information A, d A is the historical distance information of historical movement information A, (x B ,y B ) is the historical device location information of historical mobile information B, d B is the historical distance information of historical movement information B, (x C ,y C ) is the historical device location information of historical mobile information C, d C is the historical distance information of terminal C, (x p ,y p ) is the item location information.

[0092] S3032. Determine current distance information based on the object location information and the current device location information.

[0093] The specific calculation formula for the current distance information is as follows:

[0094]

[0095] Among them, (x D ,y D ) is the current device location information, (xp ,y p ) is the item location information, d C is the current distance information.

[0096] In one embodiment, the target position information also includes current direction information. Step 303 also includes: determining the current direction information according to the object position information and the current device position information. The current direction information is used to indicate the direction of the object relative to the mobile device.

[0097] In one embodiment, the mobile device is also provided with a posture sensor and an acceleration sensor. The acceleration sensor can be used to obtain the historical acceleration offset information of the mobile device during each movement, and the posture sensor is used to obtain the current direction offset information of the mobile device during the movement. In the process of position tracking, the object position information or current direction information determined by the mobile device may have certain differences. At this time, the object position information can be adjusted by the historical acceleration offset information or the current direction offset information can be adjusted by the current direction information.

[0098] In one embodiment, after step S303, the method further includes: providing information prompts according to the target position information, wherein the information prompts may be provided in the form of any one or more of sound, vibration frequency, etc., to provide specific position prompts, which is easy to operate and improves the user experience.

[0099] In this embodiment, the distance measurement during the movement of the mobile device can ensure the real-time location update and improve the accuracy of item tracking. The mobile device can track items without relying on other devices or service terminals.
