Due to space constraints and considerations for antenna performance, millimeter-wave transceiver antennas are often placed close to the bottom corner of the watch, or even tilted at a horizontal angle.

The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments".

[0030] It should be noted that the concepts of "first" and "second" mentioned in this invention are only used to distinguish different devices, modules or units, and are not used to limit the order of functions performed by these devices, modules or units or their interdependencies.

[0031] It should be noted that the terms "a" and "a plurality of" used in this invention are illustrative rather than restrictive. Those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0032] It is understood that the data involved in this technical solution (including but not limited to the data itself, the acquisition or use of the data) shall comply with the requirements of relevant laws, regulations and related provisions.

[0033] Figure 1a This is a top view of a watch provided in an embodiment of the present invention. Figure 1a It includes a watch screen 101, a watch strap slot 102, and a knob 103. Figure 1b A side view of a watch provided for an embodiment of the present invention, such as... Figure 1b As shown, Figure 1b It includes a watch case 105, a millimeter-wave transmitter / receiver module 104 (i.e., a millimeter-wave module), and a knob 103. The millimeter-wave transmitter / receiver module 104 is located near the bottom corner (lower left corner) of the watch, so that the radiation path of the millimeter-wave antenna passes through the curved bottom of the watch case. Figure 2 This is a schematic diagram of the wireless transmission path of the millimeter-wave transmitting / receiving module provided in an embodiment of the present invention. Figure 2 The system includes a millimeter-wave transmitting / receiving module 201 inside the watch, a watch case 202, a millimeter-wave transceiver box 203, and a millimeter-wave transmitting / receiving module 204 within the millimeter-wave transceiver box 203. The millimeter-wave transmitting / receiving module 201 (antenna) inside the watch is tilted at a horizontal angle. Because the dielectric constant of glass differs from that of air, incident waves refract when they enter the interface between the glass and air. The path of the refracted wave varies depending on the dielectric constant of the glass. When the transmission path deviates too far above the millimeter-wave transmitting / receiving module 204 within the millimeter-wave transceiver box 203, the transmission distance becomes too great, resulting in no reception. This is because millimeter waves are high-frequency signals, and their signal attenuation increases significantly with the square of the distance in air. These issues affect communication between the watch and the millimeter-wave transmitting / receiving module 204 within the millimeter-wave transceiver box 203, leading to a failure to transmit signals.

[0034] Figure 3 This is a schematic diagram of a millimeter-wave signal transmission system architecture provided by an embodiment of the present invention. The system is used to execute a millimeter-wave signal transmission method. Figure 3 As shown, the system includes a watch 301, a millimeter-wave transceiver box 302, a motor 303, a testing platform 304, a computer 305, and a tilt angle adjustment device. Figure 3 Not displayed. Figure 7The display includes a display screen 306; wherein the display screen 306 is connected to the computer 305, the computer 305 is connected to the test platform 304 and the millimeter-wave transceiver box 302, the test platform 304 is connected to the watch carrier 300 of the watch 301 via a motor 303; wherein the millimeter-wave transceiver box 302 is placed on the test platform 304; the millimeter-wave module in the watch 301 transmits millimeter-wave signals to the millimeter-wave module in the millimeter-wave transceiver box 302; The tilt angle adjustment device is used to move the position of the millimeter-wave module carrier in the millimeter-wave transceiver box to adjust the tilt angle of the millimeter-wave module carrier; the computer 305 is used to control the movement of the motor 303 based on the test platform 304 to drive the watch carrier 300 to move; the computer 305 is also used to read the signal strength value from the millimeter-wave module in the millimeter-wave transceiver box 302, determine the target tilt angle based on the signal strength value, and display the signal strength value on the display screen 306.

[0035] like Figure 3 As shown, the test platform 304 can serve as a platform for placing the millimeter-wave transceiver box 302, and the motor 303 can control the movement of the watch carrier 300 along the X, Y, and Z axes. The computer 305 (i.e., the host computer) can be connected to the test platform 304 via a USB 2.0 cable, allowing the computer 305 to control the movement of the motor 303 through the test platform 304. The computer 305 communicates with the millimeter-wave module (i.e., the millimeter-wave transceiver module) inside the millimeter-wave transceiver box 302 via a USB 2.0 to Type-C cable, and can read the Received Signal Strength Indication (RSSI) value and display it on the display screen 306.

[0036] In this embodiment, the tilt angle adjustment device can move the position of the millimeter-wave module carrier in the millimeter-wave transceiver box 302, thereby obtaining multiple tilt angles. At each tilt angle, the following operations are performed: acquiring the bit packet between the watch 301 and the millimeter-wave transceiver box 302, and determining the bit error rate based on the bit packet; if the bit error rate is less than a set bit error rate, the corresponding tilt angle is retained, obtaining a set number of candidate tilt angles. Among the set number of candidate tilt angles, for any candidate tilt angle, the following operations are performed: the computer 305 controls the motor 303 to move through the test platform 304, thereby moving the watch carrier 300, thereby acquiring the different coordinate positions of the watch carrier 300; at each coordinate position, the computer 305 reads the signal strength value from the millimeter-wave module in the millimeter-wave transceiver box 302, determines the target tilt angle based on the multiple signal strength values ​​of the multiple candidate tilt angles, and displays the multiple signal strength values ​​of the multiple candidate tilt angles on the display screen 306.

[0037] In this embodiment, the position of the millimeter-wave module carrier in the millimeter-wave transceiver box is moved by the tilt angle adjustment device, and the movement of the motor is controlled by a computer based on the test platform. By reading the signal strength value from the millimeter-wave module in the millimeter-wave transceiver box and determining the target tilt angle based on the signal strength value, the millimeter-wave module in the millimeter-wave transceiver box can effectively transmit signals with the millimeter-wave module in the watch based on the target tilt angle, thereby improving the transmission efficiency of millimeter-wave signals.

[0038] Figure 4 A top view of the watch carrier and millimeter-wave transceiver box provided in an embodiment of the present invention. Figure 4 This includes a watch carrier 401, a spring insert 402, a millimeter-wave transceiver box 403, a watch strap slot 404, and a knob 405. For example... Figure 4 As shown, the spring-loaded insert 402 on the watch carrier 401 is used to fix and eject the watch carrier. The watch is fixed on the watch carrier. The watch carrier 401 can be placed on the millimeter-wave transceiver box 403, which is connected to a computer. Signal transmission can be performed between the watch and the millimeter-wave module of the millimeter-wave transceiver box. Figure 5 A side view of the watch carrier and millimeter-wave transceiver box provided in an embodiment of the present invention. Figure 5 This includes a watch carrier 501, a millimeter-wave transceiver box 502, a millimeter-wave transmitting / receiving module (i.e., a millimeter-wave module) 503 inside the watch, a millimeter-wave transmitting / receiving module (i.e., a millimeter-wave module) 504 in the millimeter-wave transceiver box 502, and a millimeter-wave module carrier 505 on the millimeter-wave transceiver box 502. For example... Figure 5As shown, the millimeter-wave transmitting / receiving module (i.e., millimeter-wave module) 503 inside the watch is designed with a set horizontal tilt angle due to space limitations inside the watch. In order to achieve better transmission efficiency, the millimeter-wave module carrier 505 on the millimeter-wave transceiver box 502 can also include a set horizontal tilt angle. The millimeter-wave module carrier 505 can be fixed to the millimeter-wave transceiver box 502 by screws. The millimeter-wave transmitting / receiving module (i.e., millimeter-wave module) 504 of the millimeter-wave transceiver box 502 is on the millimeter-wave module carrier 505. Figure 6 This is a schematic diagram of the wireless transmission path of a millimeter-wave module provided in an embodiment of the present invention. Figure 6 As shown, Figure 6 The system includes a millimeter-wave transceiver box 601, a millimeter-wave transmitting / receiving module 605 within the transceiver box 601, a millimeter-wave module carrier 602 for the millimeter-wave transmitting / receiving module 605, a millimeter-wave transmitting / receiving module 604 inside the watch, and a watch case 603. The small square (black) represents the millimeter-wave module (i.e., the millimeter-wave transmitting / receiving module). When the millimeter-wave transmitting / receiving module 605 inside the transceiver box 601 transmits millimeter-wave signals to the watch based on the target tilt angle θ, the signal can propagate between the watch and the transceiver box 601 along the shortest path between the receiving and transmitting antennas, achieving efficient transmission.

[0039] For example, Figure 7 This is a schematic diagram of the tilt angle adjustment device provided in an embodiment of the present invention. Figure 7 This includes a millimeter-wave transceiver box 701, a millimeter-wave transmitting / receiving module 702 within the millimeter-wave transceiver box 701, a tilt angle adjustment device 703, a millimeter-wave transmitting / receiving module 704 inside the watch, a watch case 705, and a millimeter-wave module carrier 706 for the millimeter-wave transmitting / receiving module 702. For example... Figure 7 As shown, the tilt angle adjustment device 703 is a slide rail or a gear rack. It should be noted that in the early stages of development, a slide rail or gear rack can be added to adjust the tilt angle of the millimeter-wave module carrier 706 on the millimeter-wave transceiver box 701 to obtain an angle with better transmission efficiency. Later, when mass-producing for use in production line testing stations, the slide rail or gear rack can be removed to save costs, thereby reducing development time and costs and enhancing competitiveness.

[0040] Figure 8This is a schematic flowchart illustrating a millimeter-wave signal transmission method according to an embodiment of the present invention. This embodiment is applicable to millimeter-wave signal transmission between a wearable device and a millimeter-wave transceiver box; the wearable device is not limited in this embodiment, and can be, for example, a watch; the method can be executed by a millimeter-wave signal transmission system or a millimeter-wave signal transmission device. The millimeter-wave signal transmission device can be implemented in software and / or hardware, optionally through an electronic device, such as a mobile terminal, a PC, or a server. Figure 8 As shown, the method includes:

[0041] S810: Acquire bit packets between the watch and the millimeter-wave transceiver box.

[0042] Both the watch and the millimeter-wave transceiver box include millimeter-wave modules; the millimeter-wave modules are used to receive / transmit millimeter-wave signals; the watch is fixed inside a watch carrier, and the millimeter-wave modules inside the millimeter-wave transceiver box are fixed inside a millimeter-wave module carrier; the millimeter-wave module carrier includes multiple different tilt angles.

[0043] The watch carrier can also include a set tilt angle. The tilt angle can be understood as an angle tilted horizontally. The movement of the watch carrier moves the watch, and the movement of the millimeter-wave module carrier moves the millimeter-wave module inside the millimeter-wave transceiver box. A bit packet can be understood as the encapsulation of binary data transmitted between the watch and the millimeter-wave transceiver box, forming a bit packet.

[0044] Optionally, before acquiring the bit packet between the watch and the millimeter-wave transceiver box, the method further includes: acquiring multiple millimeter-wave module carriers; wherein each millimeter-wave module carrier includes a different tilt angle; or, controlling the movement of the millimeter-wave module carriers to adjust the tilt angle of the millimeter-wave module carriers.

[0045] In this embodiment, the millimeter-wave module carrier can include different tilt angles in the following two ways: First, in the early stage of development, multiple millimeter-wave module carriers with different tilt angles are designed; second, the movement of the millimeter-wave module carrier is controlled to adjust the tilt angle of the millimeter-wave module carrier, so that a millimeter-wave module carrier can include multiple different tilt angles.

[0046] Optionally, acquiring bit packets between the watch and the millimeter-wave transceiver box includes: acquiring bit packets between the watch and the millimeter-wave transceiver box at each tilt angle.

[0047] In this embodiment, at multiple different tilt angles, the computer can issue instructions in units of tilt angle, the millimeter-wave module of the millimeter-wave transceiver box transmits bit packets, the millimeter-wave module of the watch receives the bit packets and transmits them back to the millimeter-wave module of the millimeter-wave transceiver box, and the computer obtains the bit packets from the millimeter-wave module of the millimeter-wave transceiver box.

[0048] S820. Determine the bit error rate based on the bit packet.

[0049] In this embodiment, the bit error rate is determined by bit packets in order to filter out the tilt angle of the bit error rate that meets the conditions.

[0050] S830. Determine a set number of candidate tilt angles based on the bit error rate.

[0051] In this embodiment, the tilt angle of the bit error rate that meets the conditions can be used as the candidate tilt angle, and a set number of candidate tilt angles can be obtained. In this embodiment, there is no limit to the specific value of the set number, for example, it can be 3.

[0052] Optionally, determining a set number of candidate tilt angles based on the bit error rate includes: if the bit error rate is less than the set bit error rate, then retaining the corresponding tilt angle to obtain a set number of retained candidate tilt angles.

[0053] In this embodiment, if the bit error rate is greater than or equal to a set bit error rate, the corresponding tilt angle can be eliminated; if the bit error rate is less than the set bit error rate, the corresponding tilt angle is retained, and the retained tilt angles are used as candidate tilt angles to obtain a set number of retained candidate tilt angles. This embodiment does not limit the specific value of the set bit error rate; for example, the set bit error rate can be 1%.

[0054] For example, during the initial development phase, different tilt angles can be designed, such as 30 degrees, 35 degrees, ..., 55 degrees, 60 degrees, etc. However, the bit error rate (BER) at 30 degrees and 60 degrees is greater than 1%, which does not meet the standard for millimeter-wave transceiver modules to establish communication. Occasionally, BERs at 35 degrees and 55 degrees also exceed 1%. Therefore, the candidate tilt angles selected that achieve a BER of less than 1% and are suitable for establishing communication are 40 degrees, 45 degrees, and 50 degrees.

[0055] S840. Obtain the signal strength value corresponding to the set number of candidate tilt angles.

[0056] In this embodiment, the corresponding signal strength value can be obtained in units of candidate tilt angle.

[0057] Optionally, obtaining the signal strength value corresponding to the set number of candidate tilt angles includes: for the set number of candidate tilt angles, controlling the watch carrier to move within a set coordinate range according to a set step size at each candidate tilt angle; obtaining the coordinate position of the watch carrier after movement; and obtaining the signal strength value between the watch located at the coordinate position and the millimeter-wave transceiver box.

[0058] In this embodiment, for any candidate tilt angle, the following operations can be performed: control the watch carrier to move within a set coordinate range according to a set step size; after each step, the coordinate position of the watch carrier after movement can be obtained; obtain the signal strength value between the watch at the coordinate position and the millimeter-wave transceiver box. Thus, for any candidate tilt angle, the signal strength values ​​corresponding to multiple coordinate positions can be obtained. The set coordinate range can be understood as the coordinate range of movement on the X-axis and / or the coordinate range of movement on the Y-axis.

[0059] Optionally, controlling the watch carrier to move within a set coordinate range according to a set step size includes: controlling the watch carrier to move within a first set range of the first coordinate axis and / or a second set range of the second coordinate axis according to a set step size.

[0060] In this embodiment, there is no limitation on the specific setting step size, for example, it can be 0.5mm. In this embodiment, there is also no specific limitation on the first setting range and the second setting range. For example, the first setting range can be -1mm to 1mm, the second setting range can be -2mm to 2mm, the first coordinate axis can be the X-axis, and the second coordinate axis can be the Y-axis.

[0061] For example, the height distance Z between the center of the millimeter-wave module of the watch and the center of the millimeter-wave module of the millimeter-wave transceiver box is 3.7mm. With the center of the millimeter-wave module of the millimeter-wave transceiver box as the origin of the coordinate system, after the millimeter-wave module carrier is installed on the millimeter-wave transceiver box, the computer program controls the movement of the stepper motor: moving the position of the watch carrier, and measuring the signal strength values ​​(i.e., RSSI data) at 0.5mm steps for the X-axis coordinate from -1mm to 1mm and the Y-axis coordinate from -2mm to 2mm, for a total of 45 positions.

[0062] S850. Determine the target tilt angle based on the signal strength value, so that the millimeter-wave module in the millimeter-wave transceiver box can transmit millimeter-wave signals to the watch based on the target tilt angle.

[0063] In this embodiment, the candidate tilt angle is still used as the unit. The candidate tilt angle with the smallest change in signal strength value amplitude and the largest number of maximum signal strength values ​​can be used as the target tilt angle.

[0064] Optionally, determining the target tilt angle based on the signal strength value includes: determining the number of maximum signal strength values ​​corresponding to each candidate tilt angle; wherein the maximum signal strength value is the maximum value among the signal strength values ​​of multiple candidate tilt angles; determining the variance of the signal strength value corresponding to each candidate tilt angle; and taking the candidate tilt angle with the most maximum signal strength values ​​and / or the smallest variance of the signal strength value as the target tilt angle.

[0065] In this embodiment, for any candidate tilt angle, the following operations are performed: determining the number of maximum signal strength values; wherein the maximum signal strength value is the maximum value among the signal strength values ​​of multiple candidate tilt angles; and determining the variance of the signal strength value corresponding to the tilt angle. In this embodiment, no specific limitation is placed on the specific variance algorithm; it only needs to characterize the change in the amplitude of the signal strength value. After determining the number of maximum signal strength values ​​and the variance of the signal strength value for each candidate tilt angle, the candidate tilt angle with the largest number of maximum signal strength values ​​and / or the smallest variance of the signal strength value is selected as the target tilt angle.

[0066] For example, the candidate tilt angle (e.g., 45 degrees) that has the most maximum signal strength values ​​(e.g., -16dBm) and the smallest variance in signal strength values ​​can be used as the target tilt angle.

[0067] The technical solution of this invention involves acquiring bit packets between a watch and a millimeter-wave transceiver box; determining the bit error rate based on the bit packets; determining a set number of candidate tilt angles based on the bit error rate; acquiring the signal strength values ​​corresponding to the set number of candidate tilt angles; and determining a target tilt angle based on the signal strength values, so that the millimeter-wave module in the millimeter-wave transceiver box can transmit millimeter-wave signals to the watch based on the target tilt angle. In this embodiment, by determining a set number of candidate tilt angles through the bit error rate and determining the target tilt angle from the candidate tilt angles based on the signal strength values, the millimeter-wave module in the millimeter-wave transceiver box can effectively transmit signals to the millimeter-wave module in the watch based on the target tilt angle, thereby improving the transmission efficiency of millimeter-wave signals.

[0068] Figure 9 This is a schematic flowchart illustrating another millimeter-wave signal transmission method provided in an embodiment of the present invention. Figure 9As shown, bit packets are acquired from the millimeter-wave module of the millimeter-wave transceiver box; the bit error rate is determined based on the bit packets; it is determined whether the bit error rate is less than a set bit error rate (e.g., 1%). If the bit error rate is less than the set bit error rate, the corresponding tilt angle is retained, obtaining a set number of candidate tilt angles. If the bit error rate is greater than or less than the set bit error rate, the next tilt angle is selected, and bit packets are acquired again. At each candidate tilt angle, the watch carrier is controlled to move within a first set range of the first coordinate axis and / or a second set range of the second coordinate axis according to a set step size; the coordinate position of the watch carrier after movement is obtained; the signal strength value between the watch and the millimeter-wave transceiver box at the coordinate position is obtained, and the signal strength value is displayed on the display screen. The millimeter-wave transceiver box with different candidate tilt angles is replaced with a millimeter-wave module carrier. It is determined whether all candidate tilt angles have been measured. If all candidate tilt angles have been measured, the target tilt angle is determined based on the signal strength value. If not, the measurement continues until the signal strength value of all candidate tilt angles has been measured. At each candidate tilt angle, the watch carrier is controlled to move within a set coordinate range according to a set step size, and the signal strength value after the movement is obtained.
