[0058] Method Example

[0059] The device management method provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0060] Reference Figure 1 , shows a flow chart of the steps of a device management method provided by an embodiment of the present application, such as Figure 1 As shown, the method specifically includes the following steps:

[0061] 101. Configure a Bluetooth anchor array in each room of the management area;

[0062] 102. Determine location information of a terminal device based on the Bluetooth anchor point array;

[0063] 103. Determine the room information corresponding to the terminal device based on the location information and the floor plan corresponding to the management area.

[0064] The device management method provided by the embodiment of the present invention is applied to a server. Figure 2, shows a schematic diagram of the architecture of a device management system provided by an embodiment of the present invention. Figure 2 As shown, the device management system includes a terminal device 110, a server 120 and a Bluetooth anchor array. The Bluetooth anchor array includes Bluetooth anchors 31, 32, 33, 34 and 35. It is understandable that Figure 2 The Bluetooth anchor points included in the Bluetooth anchor point array are shown as an example only. A Bluetooth anchor point array includes at least two Bluetooth anchor points. In actual applications, the number of Bluetooth anchor points can be determined according to the size of the management area, for example, 3 Bluetooth anchor points, 5 Bluetooth anchor points, 6 Bluetooth anchor points, etc. The embodiment of the present invention does not specifically limit the number of Bluetooth anchor points in the Bluetooth anchor point array.

[0065] The server can be a standalone physical server, a server cluster or distributed system consisting of multiple physical servers, and can also provide cloud services, cloud databases, cloud computing, cloud functions, cloud storage, cloud communications, network services, middleware services, content delivery networks (CDNs), and basic cloud computing services such as big data and artificial intelligence platforms. In an optional embodiment, server 120 can be the backend server of an application used for device management in terminal device 110.

[0066] The terminal device is a smart device, which can specifically be: a smart speaker, a smart TV, a smart camera, a smart air conditioner, a smart refrigerator, a smart washing machine, a smart toilet, a smart humidifier, a sweeping robot, a smart air purifier, electric curtains, a smart lamp, a smart sensor (such as a thermometer, a barometer, an infrared sensor, a hygrometer lamp), a smart door lock, etc.

[0067] The device management method provided by the embodiment of the present invention can determine the location information of the terminal device based on the Bluetooth anchor point array configured in the management area after the terminal device is networked, and allocate room information to the terminal device according to the location information of the terminal device and the floor plan corresponding to the management area, so as to group the terminal devices and achieve more refined control and scene linkage.

[0068] It should be noted that the management area in the embodiments of the present invention can be a podium management zone, a standard floor management zone, a basement management zone, or an elevator management zone. The podium management zone is a management zone constructed by radio frequency units installed on the lower floors of a building (i.e., the podium, such as the first-floor lobby), which have large floor areas, few spatial partitions, and are open. The standard floor management zone is a management zone constructed by radio frequency units installed on floors above the podium, with relatively regular spatial spacing, typically used for residences, offices, or hotel rooms. The basement management zone is a management zone constructed by radio frequency units installed on floors below ground level, such as basements or underground garages. The elevator management zone is a management zone constructed by radio frequency units installed in the building's elevators.

[0069] In an embodiment of the present invention, the management area can be divided into at least one room or sub-area based on its spatial characteristics and apartment layout. At least two Bluetooth anchor points can be deployed in each room to form a Bluetooth anchor point array. A three-dimensional spatial coordinate system can then be established within each room or sub-area, and the position coordinates of each Bluetooth anchor point can be determined. For example, a three-dimensional spatial coordinate system can be established with the geometric center of the room or sub-area as the origin, the axis parallel to the window as the X-axis, the axis perpendicular to the wall as the Y-axis, and the axis perpendicular to the ground as the Z-axis. The position coordinates of each Bluetooth anchor point can be determined based on its position relative to the origin.

[0070] It is understandable that the Bluetooth anchor point in the embodiment of the present invention is a smart device that supports Bluetooth technology and has a relatively fixed position, such as a smart TV, a smart refrigerator, a smart washing machine, a smart toilet, a smart humidifier, a smart sensor, etc.

[0071] After a terminal device connects to the network (network configuration), its location is determined based on the Bluetooth anchor point array. For example, the terminal device transmits a timestamped broadcast signal. The Bluetooth anchor point detects signal strength (RSSI), time of flight (ToF), and other metrics, locally calculating the distance to the terminal device and determining the terminal device's relative position relative to the Bluetooth anchor point. Each Bluetooth anchor point in the Bluetooth anchor point array transmits its locally determined location information relative to the Bluetooth anchor point to a server. The server then performs high-precision positioning based on the location information sent by each Bluetooth anchor point to determine the terminal device's final location.

[0072] As an example, assume that the management area is an indoor warehouse with an area of ​​10m×10m×3m (X∈[0,10], Y∈[0,10], Z∈[0,3]). Four Bluetooth anchor points A, B, C, and D are deployed with coordinates of A(0,0,3), B(10,0,3), C(10,10,3), and D(0,10,3). The terminal device is an AGV.

[0073] The AGV periodically (1Hz) sends Bluetooth broadcast packets with a timestamp (e.g., T=10:00:00.000). The packets contain: the device ID, such as AGV-001; the broadcast timestamp, which is used for ToF calculation; and other metadata, such as the device type and battery level.

[0074] After receiving the broadcast signal, each Bluetooth anchor point calculates the terminal's relative position to itself through the following steps:

[0075] 1. Measure RSSI and ToF to calculate distance di.

[0076] Take anchor point A as an example:

[0077] The signal strength RSSI of the signal received by anchor point A is -60dBm. Substituting it into the RSSI ranging model, the calculated RSSI measurement value is:

[0078]

[0079] The timestamp of the terminal device broadcast signal is T1=10:00:00.000, and the timestamp of anchor point A receiving the broadcast signal is T2=10:00:00.034μs (signal flight time ). Substitute into the time of flight ToF ranging formula (speed of light ), the calculated distance value is:

[0080]

[0081] Taking multipath error into account, the above distance value can be corrected to 5.0m.

[0082] Fuse the RSSI and ToF results, such as taking the average, or using algorithms such as Kalman filtering to obtain the final distance between the terminal device and anchor point A. Assuming that the averaging method is used for fusion, we get = .

[0083] Furthermore, anchor point A measures the signal angle of arrival (AoA) using an antenna array (e.g., four antennas) and obtains:

[0084] Horizontal angle of incidence , that is, the angle between the terminal and the X axis in the XY plane of anchor point A is 45°; the vertical incidence angle , that is, the vertical angle between the terminal and anchor point A, that is, the angle with the Z axis is 60°.

[0085] Based on the angle and distance, calculate the local coordinates of the terminal device relative to anchor point A (with anchor point A as the origin):

[0086]

[0087] The global coordinates of anchor point A are A(0,0,3), so the initial position of the terminal device relative to the global coordinate system is:

[0088]

[0089] For other anchor points, the global preliminary position of the terminal device is calculated synchronously according to the above steps. Assume that the measurement results of other anchor points (B, C, D) are as shown in Table 1:

[0090]

[0091] Each anchor point sends the measurement results to the server. For example, the information sent by the anchor point to the server may include: anchor point ID (A / B / C / D), terminal device ID, global preliminary position of the terminal device relative to the anchor point , can also carry other auxiliary information, such as measurement errors (e.g. di standard deviation), angular error, dynamic weight ,etc.

[0092] The server considers the reliability of each anchor point (dynamic weight) based on the preliminary position sent by each anchor point. ), and finally calculate the global position P (x, y, z) of the terminal device.

[0093] For example, dynamic weight It is used to reflect the reliability of anchor data and is usually inversely proportional to the error. Assumptions:

[0094] The measurement error of anchor point A is large. , the ranging errors of anchor points B, C, and D are small, The coordinate calculation is performed using weighted fusion. The specific calculation formula is as follows:

[0095] , , (1)

[0096] Take the x coordinate as an example:

[0097] Anchor Point A: , m, , = ≈0.0236;

[0098] Anchor point B: , m, , = ≈0.1323;

[0099] Anchor point C: , m, , = ≈0.1281;

[0100] Anchor point D: , m, , = ≈0.0579.

[0101] The sum of the molecules is: 0.0236+0.1323+0.1281+0.0579≈0.3419

[0102] The sum of the denominators is:

[0103] + + + ≈0.0654

[0104] The final result is x=0.3419 / 0.0654≈5.3m.

[0105] Similarly, calculate y and z according to the above steps, and finally obtain the position P (5.1, 4.9, 1.1) of the terminal device.

[0106] Based on the calculated location P of the terminal device and the floor plan of the management area, the server can determine the room information where the terminal device is located, and then bind the device tag of the terminal device to the room tag (such as the room ID) to realize the room allocation of the terminal device, so as to achieve group management and refined control of the terminal device.

[0107] For example, you can remotely control devices by room. For example, on your way home from get off work, you can use the device management app to access the "Bedroom" group, turn on the air conditioner, and adjust the temperature in advance. Or, while on a business trip, you can check the camera feed in the "Children's Room" to confirm your child's activities. By assigning devices to rooms, you can avoid the clutter of multiple devices and quickly locate the target device by room, improving operational efficiency.

[0108] Alternatively, you can implement automated scene management based on spatial logic linkage. For example, you could trigger "bedroom" device linkage based on motion detection: the human sensor at the bedroom door detects movement and automatically turns on the bedroom night light. Or, you could trigger "living room" device linkage based on time: at 6:00 AM, the living room curtains automatically open, and so on.

[0109] Alternatively, device management and control in complex scenarios can be achieved based on the room information and control modes assigned to terminal devices. For example, in Away mode, all lights and appliances in the "living room, bedroom, and kitchen" area can be turned off with one click, while the "entrance" camera security mode is activated. Alternatively, in Movie Mode, receiving the voice command "I want to watch a movie" will dim the living room lights, turn on the TV, mute the air conditioner, and so on.

[0110] The device management method provided by an embodiment of the present invention configures a Bluetooth anchor point array within a management zone. Based on this array, the location information of terminal devices is determined. A server can then automatically determine the room information corresponding to the terminal device based on the terminal device's location information and the floor plan corresponding to the management zone. Compared to related techniques that require users to manually assign rooms to devices during batch device network configuration, the present invention achieves high-precision positioning of terminal devices through the Bluetooth anchor point array. Based on the determined location information, room information is automatically assigned to the terminal device, eliminating the need for manual user configuration and improving room allocation efficiency and accuracy.

[0111] Optionally, the step of determining the location information of the terminal device based on the Bluetooth anchor point array in step 102 includes:

[0112] Step S11: receiving first information sent by each Bluetooth anchor point in the Bluetooth anchor point array; the first information is used to reflect the position information of the Bluetooth anchor point relative to the terminal device;

[0113] Step S12: Determine the location information of the terminal device according to the first information.

[0114] Reference Figure 3 , shows a schematic diagram of the interaction between the terminal device, the Bluetooth anchor point and the server in an embodiment of the present invention. Figure 3 As shown, after the terminal device is connected to the network, it sends a broadcast signal carrying a timestamp. After receiving the broadcast signal sent by the terminal device, each Bluetooth anchor point in the Bluetooth anchor point array performs signal detection to determine the first information. For example, the Bluetooth anchor point detects the signal strength (RSSI), flight time (ToF), etc., calculates the distance between the terminal device and the local device, and determines the relative position of the terminal device relative to the Bluetooth anchor point, and then sends the first information to the server. The first information can carry the anchor point ID, the terminal device ID, and the global preliminary position of the terminal device relative to the anchor point. , can also carry other auxiliary information, such as measurement errors (e.g. di standard deviation), angular error, dynamic weight ,etc.

[0115] After receiving the first information, the server determines the terminal device's location based on the first information sent by each Bluetooth anchor point, such as the terminal device's preliminary location coordinates. It then determines the room information corresponding to the terminal device based on the terminal device's location information and the floor plan of the management area. Finally, the server can send a corresponding room tag, such as a room ID, to the terminal device based on the determined room information to notify the terminal device of the room assignment. After receiving the room ID, the terminal device can send a confirmation message to the server, informing the server of the room assignment.

[0116] In the subsequent device management process, the server can group and manage and control multiple terminal devices according to the room allocation results.

[0117] The embodiment of the present invention determines the location information of the terminal device in combination with the first information sent by each Bluetooth anchor point in the Bluetooth anchor point array, which can fully integrate multi-source data, improve the accuracy of the positioning result, and is conducive to further improving the accuracy of room allocation.

[0118] Optionally, the first information includes signal strength, arrival angle and arrival time difference of a signal transmitted between the Bluetooth anchor point and the terminal device, and the first location coordinates of the terminal device.

[0119] Determining the location information of the terminal device according to the first information in step S12 includes:

[0120] Step S21: for each Bluetooth anchor point in the Bluetooth anchor point array, determine a dynamic weight corresponding to the Bluetooth anchor point according to the signal strength, the arrival angle, and the arrival time difference;

[0121] Step S22: Determine the second position coordinates of the terminal device according to the first position coordinates corresponding to each Bluetooth anchor point and the dynamic weight.

[0122] In an embodiment of the present invention, a distributed signal processing architecture can be adopted, in which the Bluetooth anchor point first locally calculates the preliminary position of the terminal device relative to the global coordinate system, that is, the first position coordinate, to disperse the computing load of the server. The server only needs to fuse multi-source data based on the first information sent by the Bluetooth anchor point, without the need for a large number of complex calculations, thereby improving data processing efficiency.

[0123] Specifically, after each Bluetooth anchor point receives the broadcast signal, it can first calculate the first distance between itself (Bluetooth anchor point) and the terminal device based on the signal strength RSSI and flight time ToF. di.

[0124] Furthermore, the Bluetooth anchor point can measure the angle of arrival (AoA) of the signal based on an antenna array (e.g., four antennas) and calculate the local coordinates of the terminal device relative to the Bluetooth anchor point (with the Bluetooth anchor point as the origin) based on the AoA and the first distance. Then, based on the position coordinates of the Bluetooth anchor point (global coordinates) and the local coordinates of the terminal device, the preliminary position of the terminal device relative to the global coordinate system, i.e., the first position coordinates, is determined.

[0125] Each Bluetooth anchor point in the Bluetooth anchor point array sends the calculated first position coordinates to the server, and sends the signal strength RSSI, arrival angle AoA and arrival time difference TDOA to the server to assist the server in performing high-precision positioning calculations.

[0126] The server considers the reliability of the data provided by the Bluetooth anchor point based on the signal strength RSSI, arrival angle AoA and arrival time difference TDOA, and determines the dynamic weight corresponding to the Bluetooth anchor point. It is understood that the dynamic weight is used to reflect the data reliability of the Bluetooth anchor point, which is usually inversely proportional to the error. For example, if the signal strength of a certain anchor point is high and the ranging error is small, then If the signal is interfered with (such as the Bluetooth anchor point is blocked), Smaller.

[0127] The server fuses the first position coordinates calculated by each Bluetooth anchor point based on the dynamic weight to obtain the final second position coordinates of the terminal device. The specific fusion method can refer to the processing process shown in the above formula (1).

[0128] The embodiment of the present invention determines the dynamic weight corresponding to each Bluetooth anchor point by comprehensively considering the signal strength, arrival angle and arrival time difference, and fuses the positioning information of the Bluetooth anchor point array based on the dynamic weight. This can suppress the influence of anchor point data with large errors on the final positioning result, achieve high-precision estimation of the global position of the terminal device, improve positioning accuracy, and help further improve the accuracy of the room allocation result of the terminal device.

[0129] Optionally, determining the dynamic weight corresponding to the Bluetooth anchor point according to the signal strength, the arrival angle, and the arrival time difference in step S21 includes:

[0130] Sub-step S211: determining a first weight and a first weight coefficient corresponding to the signal strength, a second weight and a second weight coefficient corresponding to the arrival angle, and a third weight and a third weight coefficient corresponding to the arrival time difference;

[0131] Sub-step S212: performing a weighted sum operation based on the first weight, the first weight coefficient, the second weight, the second weight coefficient, the third weight, and the third weight coefficient to obtain the dynamic weight.

[0132] As an example, the dynamic weight in the embodiment of the present invention can be expressed as:

[0133] (2)

[0134] in, is the first weight coefficient corresponding to the signal strength, is the first weight corresponding to the signal strength RSSI; is the second weight coefficient corresponding to the angle of arrival AoA, is the second weight corresponding to the angle of arrival AoA; is the third weight coefficient corresponding to the time difference of arrival TDOA, is the third weight corresponding to the time difference of arrival TDOA.

[0135] According to the above formula (2), the first weight, the second weight and the third weight are weighted and summed to obtain the dynamic weight in the embodiment of the present invention: .

[0136] Optionally, the method further includes:

[0137] At least one of the first weight coefficient, the second weight coefficient, and the third weight coefficient is adjusted according to the environment information of the terminal device.

[0138] It's understandable that RSSI is significantly affected by environmental attenuation but is simple to calculate; AoA requires an antenna array and offers high accuracy but is affected by multipath; and TDOA requires time synchronization and offers high accuracy but requires complex equipment. The embodiments of the present invention integrate these factors when calculating dynamic weights. Specifically, in embodiments of the present invention, the weight coefficients can be adjusted based on the real-time environment of the terminal device. For example, AoA can be weighted more in stable signal environments, while TDOA can be weighted more in complex multipath environments.

[0139] The embodiment of the present invention dynamically adjusts the weight coefficient based on environmental information so that the calculation result can adapt to the environment in which the terminal device is located, thereby minimizing the impact of the environment on the positioning result and improving the positioning accuracy.

[0140] Optionally, the method further includes:

[0141] Step S31: Determine the device identification and total number of terminal devices for batch network configuration in the management area;

[0142] Step S32: Determine the time slice corresponding to each terminal device according to the total number of devices and the network distribution period;

[0143] Step S33: Generate second information according to the time slice and the device identifier;

[0144] Step S34: Send the second information to the terminal device, so that the terminal device can establish a network connection within the corresponding time slice.

[0145] In embodiments of the present invention, dynamic time-division multiplexing can also be used to configure network configuration and room allocation for terminal devices. Specifically, a time slice corresponding to each terminal device can be determined based on the total number of terminal devices requiring batch network configuration in the management area and a preset network configuration time. Second information can be generated based on the terminal device's device identifier and the time slice, and the second information can be sent to the terminal device, instructing the terminal device to establish a network connection within the corresponding time slice.

[0146] When multiple devices simultaneously send network connection requests to the server, each device is allocated a specific time slot. During this time slot, the device can send its network configuration information, such as its device identification and configuration parameters. This prevents conflicts caused by multiple devices sending data simultaneously, improving the success rate and efficiency of network configuration.

[0147] Furthermore, in embodiments of the present invention, the time slice size and allocation order for each terminal device can be flexibly adjusted based on the actual transmission needs of the terminal device. For example, if a terminal device has a lot of data to transmit, more time slices can be allocated to it; if a device temporarily has no data to transmit, its time slice can be temporarily allocated to other devices with data needs.

[0148] In summary, the device management method provided by the embodiments of the present invention configures a Bluetooth anchor array within a management zone and determines the location information of terminal devices based on the Bluetooth anchor array. The server can then automatically determine the room information corresponding to the terminal device based on the terminal device's location information and the floor plan corresponding to the management zone. Compared to related techniques that require users to manually set the room to which devices belong when configuring a batch of devices, the embodiments of the present invention achieve high-precision positioning of terminal devices through the Bluetooth anchor array, automatically assigning room information to terminal devices based on the determined location information without requiring manual user configuration, thereby improving the efficiency and accuracy of room allocation.
