Description

Technical Field

[0001] This application relates to the field of smart glasses technology, and in particular to a common coil power and data transmission method and related apparatus for smart glasses hinges. Background Technology

[0002] In existing technologies, the frame side and temple side of smart glasses are usually connected by a hinge. The temple side is equipped with electronic components such as sensors, communication modules, and interaction modules. Therefore, power transmission and data transmission are required between the frame side and the temple side to ensure the normal operation of the electronic components on the temple side.

[0003] Existing technologies typically employ physical electrical connection structures such as flexible circuit boards, wires, spring contacts, or connectors to transmit electrical energy and data signals between the frame side and the temple side. Because these physical electrical connection structures need to pass through or cross the hinge area, which undergoes frequent opening and closing rotation during the use of smart glasses, they are susceptible to repeated bending, pulling, wear, or poor contact, leading to abnormal power supply, unstable data transmission, or even complete device malfunction.

[0004] Existing technologies also include solutions that use wireless transmission to reduce reliance on physical electrical connections at the hinge. However, the hinge area of ​​smart glasses has limited space. If different transmission structures are used for power transmission and data transmission respectively, it will increase the structural complexity and assembly difficulty of the hinge area, and occupy more hinge space. At the same time, different transmission structures may interfere with each other, affecting the efficiency of power transmission and the stability of data transmission. Summary of the Invention

[0005] This application provides a common coil power and data transmission method and related device for smart glasses hinges, which can realize stable transmission of electrical energy and data between the frame side and the temple side.

[0006] The first aspect of this application provides a common coil power and data transmission method for a smart glasses hinge, applied to smart glasses. The smart glasses include a frame side and a temple side connected by a hinge. The frame side is provided with a first inductive coupling coil, and the temple side is provided with a second inductive coupling coil. The first inductive coupling coil and the second inductive coupling coil constitute a single pair of coil transmission channels spanning the hinge. The method includes:

[0007] According to the transmission cycle, power transmission time slots and data transmission time slots are alternately configured on the single pair of coil transmission channels; During the power transmission time slot, inductive electrical energy is transmitted from the frame side to the temple side through the single pair of coil transmission channels. During the data transmission time slot, data is transmitted between the frame side and the temple side via the single pair of coil transmission channels.

[0008] Optionally, during the data transmission time slot, data transmission is performed between the frame side and the temple side via the single pair of coil transmission channels, including: The data transmission time slot is divided into downlink data transmission segments and uplink data transmission segments; Within the downlink data transmission segment, downlink data is transmitted from the frame side to the temple side via the single pair of coil transmission channels; Within the uplink data transmission segment, uplink data is transmitted from the temple side to the frame side via the single pair of coil transmission channels.

[0009] Optionally, transmitting downlink data from the frame side to the temple side via the single pair of coils through the downlink data transmission channel within the downlink data transmission segment includes: On the frame side, the first carrier signal applied to the first inductive coupling coil is modulated according to the downlink data to be transmitted; The modulated first carrier signal is received via the second inductive coupling coil on the temple side; The modulated first carrier signal is demodulated on the temple side to obtain the downlink data.

[0010] Optionally, transmitting uplink data from the temple side to the frame side via the single pair of coil transmission channels within the uplink data transmission segment includes: The load state of the second inductive coupling coil side is switched on the temple side according to the uplink data to be transmitted; The change in reflection impedance on the first inductive coupling coil side caused by the load state switching is detected on the frame side; The uplink data is obtained by demodulating the reflection impedance change on the side of the lens frame.

[0011] Optionally, the inductive power transfer from the frame side to the temple side via the single pair of coils during the power transmission time slot includes: A second carrier signal is applied to the first inductive coupling coil on the side of the mirror frame; Electrical energy is received via the second inductive coupling coil on the temple side; The electrical energy received by the second inductive coupling coil on the temple side is rectified and regulated, and the rectified and regulated electrical energy is supplied to the temple side load and the energy storage unit, so that when the data transmission time slot arrives, the energy storage unit supplies power to the temple side load.

[0012] Optionally, the method further includes: Before entering the power transmission time slot, the first inductive coupling coil is connected to the power drive path and the data communication path is disconnected; Before entering the data transmission time slot, the first inductive coupling coil is connected to the data communication path, and the power drive path is disconnected.

[0013] Optionally, the step of alternately configuring power transmission time slots and data transmission time slots on the single pair of coil transmission channels according to the transmission period includes: Obtain the power consumption and / or data transmission requirements of the temple side; Based on the power demand and / or the data transmission demand, determine the duration of the power transmission time slot and the data transmission time slot within the transmission cycle, respectively. The power transmission time slot and the data transmission time slot are alternately configured on the single pair of coil transmission channels according to the stated duration.

[0014] Optionally, the method further includes: During the execution of the power transmission time slot and / or the data transmission time slot, at least one of the following is collected: temple-side received power, temple-side received signal strength, frame-side demodulation quality, and communication error rate, wherein the communication error rate is the communication error rate between the frame side and the temple side. Based on the acquisition results, the coupling state parameters between the first inductive coupling coil and the second inductive coupling coil are determined; When the coupling state parameter indicates that the coupling between the first inductive coupling coil and the second inductive coupling coil is weakened, the carrier drive power in the power transmission time slot is increased, and / or the data transmission rate in the data transmission time slot is decreased. When the coupling state parameter indicates enhanced coupling between the first inductive coupling coil and the second inductive coupling coil, the carrier drive power in the power transmission time slot is reduced, and / or the data transmission rate in the data transmission time slot is increased.

[0015] A second aspect of this application provides smart glasses for implementing the method of the first aspect and any possible implementation thereof. The smart glasses include a frame side and a temple side connected by a hinge.

The smart glasses include: A configuration unit is used to alternately configure power transmission time slots and data transmission time slots on the single pair of coil transmission channels according to the transmission cycle; A power transmission unit is used to transmit inductive power from the frame side to the temple side through the single pair of coil transmission channels during the power transmission time slot. The data transmission unit is used to transmit data between the frame side and the temple side via the single pair of coil transmission channels during the data transmission time slot.

[0016] A third aspect of this application provides an electronic device, comprising: Processor, memory, input / output units, and bus; The processor is connected to the memory, the input / output unit, and the bus; The memory stores a program, and the processor calls the program to execute the method of the first aspect and any possible implementation of the first aspect.

[0017] The fourth aspect of this application provides a computer-readable storage medium storing a program that, when executed on a computer, causes the computer to perform the methods of the first aspect and any possible implementation thereof.

[0018] As can be seen from the above technical solutions, this application has the following advantages: In this application, the first inductively coupled coil and the second inductively coupled coil constitute a single-pair coil transmission channel spanning the hinge. The power transmission time slot and the data transmission time slot are alternately configured according to the transmission cycle, enabling this single-pair coil transmission channel to be used for inductive power transmission and data transmission at different time periods. Therefore, by setting only one pair of inductively coupled coils in the hinge area of ​​the smart glasses, both the power supply and data transmission needs between the frame side and the temple side can be met, reducing the number of coils and conductive connection structures in the hinge area, increasing the freedom of hinge area structural design, and improving the long-term reliability of the smart glasses.

Detailed Implementation

[0021] This application provides a common coil power and data transmission method and related device for smart glasses hinges, used to achieve stable transmission of electrical energy and data between the frame side and the temple side.

[0022] The embodiments of this application will now be described with reference to the accompanying drawings.

[0023] Please see Figure 1 , Figure 1 An embodiment of the common coil power and data transmission method for the hinge of smart glasses provided in this application is applied to smart glasses. The smart glasses include a frame side and a temple side connected by a hinge. The frame side is provided with a first inductive coupling coil, and the temple side is provided with a second inductive coupling coil. The first inductive coupling coil and the second inductive coupling coil form a single pair of coil transmission channels across the hinge. This embodiment includes: 101. According to the transmission cycle, power transmission time slots and data transmission time slots are alternately configured on a single pair of coil transmission channels; The frame divides the working time of the single-coil transmission channel according to a preset transmission cycle, so that the single-coil transmission channel is in power transmission mode and data transmission mode at different time periods. The power transmission time slot and the data transmission time slot alternate in time, with the power transmission time slot used for power transmission and the data transmission time slot used for data transmission. Since power transmission and data transmission do not occupy the single-coil transmission channel at the same time, the same pair of inductively coupled coils can perform power transmission function and data transmission function at different time periods.

[0024] The transmission cycle can be a continuously repeating periodic time unit. Each transmission cycle may include one power transmission time slot and one data transmission time slot, or it may include multiple power transmission time slots and multiple data transmission time slots, as long as the power transmission time slots and data transmission time slots are alternately configured on a single pair of coil transmission channels. The specific durations of the power transmission time slots and data transmission time slots can be preset according to the actual design needs of the smart glasses; this embodiment does not limit the specific ratio of their durations.

[0025] 102. During the power transmission time slot, inductive power is transmitted from the frame side to the temple side through a single pair of coil transmission channels. During the power transmission time slot, the frame side acts as the power transmitting side, and the temple side acts as the power receiving side. An inductive coupling relationship is formed between the first and second inductive coupling coils, allowing power to be transmitted from the frame side to the temple side via a single pair of coils spanning the hinge. Since the first inductive coupling coil is located on the frame side and the second inductive coupling coil is located on the temple side, no physical wire needs to pass through the hinge area between them, enabling non-contact power transmission between the two sides of the hinge.

[0026] During this power transmission time slot, the single pair of coil transmission channels primarily undertakes the function of inductive power transmission, allowing the temple side to obtain the power required to maintain the operation of its electronic components. The temple-side electronic components may include functional circuits or load circuits disposed on the temple side. Since power transmission is achieved via the first and second inductive coupling coils, the smart glasses do not require a conductive connection structure passing through the hinge at the hinge for power supply between the frame side and the temple side.

[0027] 103. During the data transmission time slot, data is transmitted between the frame side and the temple side through a single pair of coil transmission channels.

[0028] During the data transmission time slot, the single-coil transmission channel switches from power transmission to data transmission. The first and second inductively coupled coils are used to transmit data signals between the frame side and the temple side. Data can be transmitted from the frame side to the temple side, or from the temple side to the frame side, or between the frame side and the temple side according to the control requirements of the smart glasses. This embodiment does not limit the specific direction, specific communication segment, or specific modulation method of data transmission.

[0029] During this data transmission time slot, control data, status data, sensor data, or other data related to the operation of the smart glasses can be transmitted between the frame side and the temple side. Since the data transmission is still completed via a single pair of coils consisting of the first and second inductive coupling coils, the data connection between the frame side and the temple side does not need to be achieved through a flexible circuit passing through the hinge.

[0030] In this embodiment, the first inductively coupled coil and the second inductively coupled coil form a single-pair coil transmission channel spanning the hinge. The power transmission time slot and the data transmission time slot are alternately configured according to the transmission cycle, allowing this single-pair coil transmission channel to be used for inductive power transmission and data transmission at different time periods. Therefore, by setting only one pair of inductively coupled coils in the hinge area of ​​the smart glasses, both the power supply and data transmission needs between the frame side and the temple side can be met, reducing the number of coils and conductive connection structures in the hinge area, increasing the freedom of hinge area structural design, and improving the long-term reliability of the smart glasses.

[0031] Please see Figure 2 In some embodiments of this application, step 103 in the above embodiments, which involves data transmission between the frame side and the temple side via a single pair of coil transmission channels during the data transmission time slot, may include the following steps: 201. Divide the data transmission time slot into downlink data transmission segments and uplink data transmission segments; Within a data transmission time slot, the frame side divides the time slot into a downlink data transmission segment and an uplink data transmission segment according to a preset communication timing sequence. The downlink data transmission segment is used for the frame side to send downlink data to the temple side, and the uplink data transmission segment is used for the temple side to send uplink data to the frame side. The downlink and uplink data transmission segments are staggered in time, allowing the frame side and temple side to share a single pair of coil transmission channels to complete bidirectional data transmission within the same data transmission time slot.

[0032] The downlink and uplink data transmission segments can be configured in the order of downlink first, then uplink, or other pre-agreed sequences according to communication control requirements. Both the frame side and the temple side determine whether they are currently in the downlink or uplink data transmission segment based on this communication timing, thereby preventing the frame side and temple side from simultaneously sending data to a single pair of coil transmission channels.

[0033] 202. On the frame side, the first carrier signal applied to the first inductive coupling coil is modulated according to the downlink data to be transmitted; During the downlink data transmission segment, the frame side acquires the downlink data to be transmitted to the temple side, and modulates the first carrier signal applied to the first inductive coupling coil according to the downlink data, so that the detectable parameters of the first carrier signal change with the symbol state of the downlink data. The detectable parameters may include the amplitude, frequency, phase, or other signal parameters that can be identified by the temple side of the first carrier signal.

[0034] Downlink data may include control commands, configuration data, synchronization information, or other data that needs to be received by the temple side, sent from the frame side to the temple side. The first carrier signal, modulated by the data, is output by the first inductive coupling coil and transmitted to the temple side through the inductive coupling relationship between the first and second inductive coupling coils.

[0035] 203. The modulated first carrier signal is received on the temple side via a second inductive coupling coil; Within the downlink data transmission segment, the second inductively coupled coil receives the modulated first carrier signal coupled and transmitted by the first inductively coupled coil, and provides the received inductive signal to the data receiving circuit on the temple side. Since the first and second inductively coupled coils form a single pair of coils transmission channel across the hinge, downlink data does not need to be transmitted via wires or flexible circuits passing through the hinge.

[0036] When the temple side receives the modulated first carrier signal, it can determine that the currently received signal belongs to the downlink data transmission process based on the downlink data transmission segment in the data transmission time slot, and then perform subsequent data recovery processing on the signal received by the second inductive coupling coil.

[0037] 204. Demodulate the modulated first carrier signal on the temple side to obtain downlink data.

[0038] The data receiving circuit on the temple side demodulates the modulated first carrier signal received by the second inductive coupling coil, identifies the signal changes in the first carrier signal corresponding to the downlink data symbols, and recovers the downlink data transmitted from the frame side based on these signal changes. The recovered downlink data can be read and executed by the control circuit, sensing circuit, functional circuit, or other electronic components on the temple side.

[0039] After the downlink data demodulation is completed, the temple side can perform corresponding adjustments to the operating status, parameter configuration, or data processing based on the demodulated downlink data. Thus, the frame side can transmit data to the temple side using the same single pair of coil transmission channels.

[0040] 205. On the temple side, switch the load state on the second inductive coupling coil side according to the uplink data to be transmitted; Within the uplink data transmission segment, the temple side acquires the uplink data to be transmitted to the frame side, and switches the load state of the second inductive coupling coil side according to the uplink data. The load state of the second inductive coupling coil side may include at least two different equivalent impedance states, each corresponding to a different symbol state in the uplink data.

[0041] The temple side can control the connection or disconnection of the load branch associated with the second inductive coupling coil based on the uplink data, causing the equivalent load on the second inductive coupling coil side to change with the uplink data. This load state change is reflected to the frame side through the inductive coupling relationship between the first and second inductive coupling coils.

[0042] 206. Detect the change in reflection impedance on the first inductive coupling coil side due to load state switching on the frame side; Within the uplink data transmission segment, the frame side detects changes in the electrical signal on the first inductive coupling coil side and identifies changes in reflected impedance caused by the load state switching on the second inductive coupling coil side. Since changes in the load state on the second inductive coupling coil side alter the coupling response of a single pair of coil transmission channels, the first inductive coupling coil side can sense the reflected impedance change corresponding to this load state change.

[0043] The frame side can obtain a detection signal corresponding to the load state switching of the temple side by detecting voltage changes, current changes, phase changes, or other parameters that can characterize the change in reflective impedance on the first inductive coupling coil side. This detection signal is used to subsequently recover the uplink data transmitted by the temple side.

[0044] 207. Demodulate the data on the side of the mirror frame based on the change in reflection impedance to obtain the uplink data.

[0045] The lens frame side demodulates the detected changes in reflective impedance, identifies the uplink data symbol state corresponding to the changes in reflective impedance, and recovers the uplink data transmitted by the temple side. The uplink data may include temple side status data, sensor data, response data, or other data that needs to be fed back to the lens frame side.

[0046] After demodulating the uplink data, the frame side can perform subsequent control, recording, judgment, or processing based on the obtained uplink data. Thus, within the same data transmission time slot, a single pair of coil transmission channels is first used to transmit downlink data from the frame side to the temple side, and then used to transmit uplink data from the temple side to the frame side, enabling bidirectional data transmission between the frame side and the temple side without adding additional coil pairs.

[0047] In this embodiment, the data transmission time slot is divided into a downlink data transmission segment and an uplink data transmission segment, so that the process of sending downlink data from the frame side to the temple side and the process of sending uplink data from the temple side to the frame side are separated in time, avoiding data conflicts caused by the frame side and the temple side simultaneously occupying a single pair of coil transmission channels. The frame side uses carrier modulation to send downlink data, while the temple side uses load state switching to form a change in reflective impedance and send uplink data. This allows both downlink and uplink data transmission to be completed based on the same single pair of coil transmission channels formed by the first and second inductive coupling coils. Thus, bidirectional data communication between the frame side and the temple side can be achieved without adding additional data coils or hinge conductive connection structures, improving the structural compactness of the hinge area and the reliability of data transmission.

[0048] Please see Figure 3 In some embodiments of this application, step 102 in the above embodiments, which involves inductive power transmission from the frame side to the temple side via a single pair of coil transmission channels during the power transmission time slot, may include the following steps: 301. Apply a second carrier signal to the first inductive coupling coil on the side of the mirror frame; During the power transmission time slot, a second carrier signal is applied to the first inductively coupled coil from the frame side, causing the first inductively coupled coil to form an alternating electromagnetic field in the hinge region. The second carrier signal can be generated by the power drive circuit on the frame side and configured according to the electrical parameters of the first inductively coupled coil and the inductive coupling relationship between the first and second inductively coupled coils. Under the action of the second carrier signal, the first inductively coupled coil acts as a power transmission coil, enabling electrical energy to be transmitted to the temple side via a single pair of coils spanning the hinge.

[0049] It should be noted that, in this application, the first carrier signal and the second carrier signal are used to distinguish the different signal uses of the single-pair coil transmission channel in the data transmission time slot and the power transmission time slot. The first carrier signal is used in the data transmission time slot, where it can modulate the downlink data to be transmitted so that the downlink data is transmitted via the first inductive coupling coil and the second inductive coupling coil; the second carrier signal is used in the power transmission time slot, where it is used to drive inductive power transmission between the first inductive coupling coil and the second inductive coupling coil. The first carrier signal and the second carrier signal can be signals output by the same carrier generation circuit in different time slots, or signals output by different carrier generation circuits respectively; this application does not limit this.

[0050] The second carrier signal can be an AC drive signal suitable for near-field inductive coupling transmission. The second carrier signal is continuously or intermittently applied to the first inductive coupling coil during the power transmission time slot on the frame side, so that the first inductive coupling coil and the second inductive coupling coil maintain an inductive coupling state for power transmission.

[0051] 302. Electrical energy is received on the temple side via a second inductive coupling coil; During the power transmission time slot, the second inductive coupling coil on the temple side receives electrical energy transmitted by the first inductive coupling coil via inductive coupling. The second inductive coupling coil is located on the temple side and forms a relative coupling relationship with the first inductive coupling coil in the hinge region. Therefore, the second inductive coupling coil can generate an induced electrical signal under the action of the alternating electromagnetic field formed by the first inductive coupling coil.

[0052] The electrical energy received by the second inductive coupling coil is output to the rear circuit on the temple side in the form of an induced AC signal. Since the electrical energy reception is completed by the second inductive coupling coil, the temple side does not need to rely on a physical conductive connector passing through the hinge area to obtain electrical energy from the frame side.

[0053] 303. The electrical energy received by the second inductive coupling coil on the temple side is rectified and regulated, and the rectified and regulated electrical energy is supplied to the temple side load and the energy storage unit, so that when the data transmission time slot arrives, the energy storage unit supplies power to the temple side load.

[0054] The induced AC signal received by the second inductive coupling coil on the temple side is input to the rectifier and voltage regulator circuit. The rectifier and voltage regulator circuit rectifies and regulates the induced AC signal to generate a DC supply voltage suitable for the load on the temple side. The rectified and regulated electrical energy supplies both the load on the temple side and the energy storage unit, enabling the load on the temple side to obtain operating power during the power transmission time slot and allowing the energy storage unit to replenish electrical energy during the power transmission time slot.

[0055] The temple-side load may include functional circuits, detection circuits, communication circuits, sensing circuits, or other electronic components requiring power, all located on the temple side. The energy storage unit can be a capacitor-type energy storage device or other device capable of storing and releasing electrical energy for a short period. The rectified and regulated electrical energy simultaneously supplies both the temple-side load and the energy storage unit, ensuring that the electrical energy received during the power transmission time slot meets immediate power supply needs while also providing energy reserves for the continuity of power supply during subsequent data transmission time slots.

[0056] In this way, when the data transmission time slot arrives, a single pair of coil transmission channels is used for data transmission between the frame side and the temple side, while the temple side load can be powered by the energy storage unit. The energy storage unit receives and stores rectified and regulated electrical energy during the power transmission time slot, and releases electrical energy to the temple side load during the data transmission time slot, so that the temple side load maintains a continuous working state during the alternating execution of power transmission and data transmission.

[0057] When the energy storage unit supplies power to the load on the temple side, it can maintain the operating voltage of the load on the temple side within the allowable range, enabling the temple side to perform normal data reception, data transmission, or other operational operations during the data transmission time slot. Therefore, even if a single pair of coil transmission channels is mainly used for data transmission during the data transmission time slot, the load on the temple side can still maintain power supply continuity by relying on the energy storage unit.

[0058] In this embodiment, the frame side applies a second carrier signal to the first inductive coupling coil during the power transmission time slot, and the temple side receives electrical energy using the second inductive coupling coil. After rectification and voltage regulation on the temple side, the energy is supplied to the temple side load and energy storage unit, enabling the temple side to obtain stable power from a single pair of coil transmission channels. The energy storage unit supplies power to the temple side load during the data transmission time slot, ensuring that the temple side load does not lose power due to power transmission pauses when the power transmission time slot and data transmission time slot alternate, thereby improving the continuity of power supply on the temple side and the operational stability of the common coil transmission at the hinge of the smart glasses.

[0059] Please see Figure 4 In some embodiments of this application, the method may further include the following steps: 401. Before entering the power transmission time slot, connect the first inductive coupling coil to the power drive path and disconnect the data communication path; Before entering the power transmission time slot, the frame side switches the circuit connection state of the first inductive coupling coil according to the time slot control signal in the transmission cycle, electrically connecting the first inductive coupling coil to the power drive path and disconnecting it from the data communication path. The power drive path provides a drive signal for inductive power transmission to the first inductive coupling coil during the power transmission time slot. After the first inductive coupling coil is connected to the power drive path, it can participate in the inductive power transmission from the frame side to the temple side as a power transmitting coil on the frame side.

[0060] When the first inductively coupled coil is connected to the power drive path, the data communication path is disconnected from the first inductively coupled coil, so that the data communication path does not participate in the coil driving process within the power transmission time slot. Therefore, the first inductively coupled coil mainly undertakes the function of power transmission within the power transmission time slot, avoiding circuit state conflicts caused by the data communication path and the power drive path being simultaneously connected to the first inductively coupled coil during power transmission.

[0061] 402. Before entering the data transmission time slot, connect the first inductive coupling coil to the data communication path and disconnect the power drive path.

[0062] Before entering the data transmission time slot, the frame side switches the circuit connection state of the first inductive coupling coil again according to the time slot control signal in the transmission cycle, electrically connecting the first inductive coupling coil to the data communication path and disconnecting it from the power drive path. The data communication path is used to cooperate with the first inductive coupling coil to transmit and / or receive data during the data transmission time slot. After the first inductive coupling coil is connected to the data communication path, it can participate in data transmission between the frame side and the temple side as a data transmission coil on the frame side.

[0063] When the first inductively coupled coil is connected to the data communication path, the power drive path is disconnected from the first inductively coupled coil, so that the power drive path does not participate in the data communication process within the data transmission time slot. Therefore, the first inductively coupled coil primarily undertakes the data transmission function within the data transmission time slot, preventing the power drive path from affecting the data communication path during data transmission.

[0064] In this embodiment, before entering the power transmission time slot, the first inductive coupling coil is connected to the power drive path and disconnected from the data communication path. Before entering the data transmission time slot, the first inductive coupling coil is connected to the data communication path and disconnected from the power drive path. This allows the first inductive coupling coil to be connected to the corresponding functional path in different time slots, reducing the mutual influence between the power drive path and the data communication path and avoiding drive conflicts caused by the same inductive coupling coil being connected to two types of functional paths at the same time. This improves the circuit switching determinism and transmission stability during the time-division transmission process of the common coil.

[0065] Please see Figure 5 In some embodiments of this application, step 101 in the above embodiments, which alternately configures the power transmission time slot and the data transmission time slot on a single pair of coil transmission channels according to the transmission cycle, may include the following steps: 501. Obtain the power consumption and / or data transmission requirements of the temple side of the glasses; The frame side can obtain the power consumption and / or data transmission requirements of the temple side. The temple side's power consumption requirement characterizes the energy demand of the temple-side load under current operating conditions, while the data transmission requirement characterizes the data transmission duration requirement between the frame and temple sides under current operating conditions. The power consumption requirement can be determined based on the temple-side load's operating mode, load power consumption, power supply status, or other information reflecting the temple-side's power consumption; the data transmission requirement can be determined based on the amount of data to be transmitted, data type, communication frequency, or real-time communication requirements.

[0066] In one alternative approach, the frame side can determine the power consumption and / or data transmission requirements of the temple side based on a preset operating mode. For example, when the temple side load is in a high-power operating mode, it can be determined that the temple side has a high power consumption requirement; when a large amount of control data or status data needs to be transmitted between the frame side and the temple side, it can be determined that there is a high data transmission requirement between the temple side and the frame side. In another alternative approach, the temple side can also feed back information related to power consumption and / or data transmission requirements to the frame side, enabling the frame side to determine the configuration basis for power transmission time slots and data transmission time slots in subsequent transmission cycles.

[0067] 502. Determine the duration of the power transmission time slot and the data transmission time slot within the transmission cycle based on the power demand and / or data transmission demand, respectively; Based on the acquired power demand and / or data transmission demand, the frame side determines the duration of the power transmission time slot and the duration of the data transmission time slot within the transmission cycle, respectively. When the power demand is high, the duration of the power transmission time slot within the transmission cycle can be increased, allowing the single-coil transmission channel to have a longer power transmission time within that transmission cycle; when the data transmission demand is high, the duration of the data transmission time slot within the transmission cycle can be increased, allowing the single-coil transmission channel to have a longer data transmission time within that transmission cycle.

[0068] The durations of power transmission time slots and data transmission time slots can be allocated given a fixed total transmission cycle duration, or determined together with the total transmission cycle duration while meeting the basic requirements for power transmission and data transmission. If both the power consumption and data transmission requirements on the temple side are high, the relative durations of the power transmission time slots and data transmission time slots can be determined based on their priorities, the temple side's operating mode, or preset configuration rules. Therefore, the durations of the power transmission time slots and data transmission time slots do not need to be fixed but can be matched to the operational requirements on the temple side.

[0069] 503. Power transmission time slots and data transmission time slots are alternately configured on a single pair of coil transmission channels according to their duration.

[0070] The frame side configures the time slot structure within the transmission cycle according to the determined power transmission time slot duration and data transmission time slot duration, causing the single-coil transmission channel to alternately enter the power transmission state and data transmission state according to the configured time slot structure. When the power transmission time slot arrives, the single-coil transmission channel is used for inductive power transmission from the frame side to the temple side; when the data transmission time slot arrives, the single-coil transmission channel is used for data transmission between the frame side and the temple side.

[0071] The configured power transmission time slots and data transmission time slots can be used continuously over multiple transmission cycles, or they can be redefined and updated after new power demand and / or data transmission demand is obtained. Therefore, the configuration of power transmission time slots and data transmission time slots within a transmission cycle can be adjusted according to changes in the operating requirements on the temple side, enabling a single pair of coil transmission channels to achieve an adaptive allocation between power transmission time and data transmission time.

[0072] In this embodiment, the frame side acquires the power consumption and / or data transmission requirements of the temple side, and determines the duration of the power transmission time slot and data transmission time slot within the transmission cycle accordingly. This ensures that the time slot configuration of a single pair of coil transmission channels corresponds to the actual operating requirements of the temple side. Increasing the power transmission time slot duration when the power consumption on the temple side is high, and increasing the data transmission time slot duration when the data transmission requirements are high, helps avoid the problem of insufficient power transmission time or insufficient data transmission time under a fixed time slot configuration. This improves the utilization efficiency of the common coil transmission channel and the operational adaptability of the smart glasses under different working states.

[0073] Please see Figure 6 In some embodiments of this application, the method may further include the following steps: 601. During the execution of the power transmission time slot and / or data transmission time slot, collect at least one of the following: temple-side received power, temple-side received signal strength, frame-side demodulation quality, and communication error rate. During the execution of the power transmission time slot, the received power on the temple side can be collected to reflect the strength of the electrical energy received by the second inductive coupling coil from the first inductive coupling coil; during the execution of the data transmission time slot, at least one of the received signal strength on the temple side, demodulation quality on the frame side, and communication error rate can be collected to reflect the data transmission status of the single pair of coil transmission channels under the current hinge posture. The received power on the temple side can be obtained by detecting the received voltage, received current, or power supply output status of the second inductive coupling coil on the temple side; the received signal strength on the temple side can be obtained by detecting the amplitude or energy of the data signal received by the second inductive coupling coil on the temple side; the demodulation quality on the frame side can be determined by the frame side based on the amplitude stability, phase stability, symbol decision margin, or synchronization hold status during the data demodulation process; the communication error condition refers to the communication error condition generated during communication between the frame side and the temple side. Specifically, the communication error condition is used to characterize the situation where the data transmitted between the frame side and the temple side is judged as erroneous at the receiving end, including inconsistent received data and transmitted data, data verification failure, abnormal frame data parsing, missing acknowledgment response, or the need to retransmit data. The communication error condition can be determined based on the data verification results, retransmission status, or error statistics between the frame side and the temple side.

[0074] The aforementioned data acquisition objects can be used individually or in combination. For example, when only the power transmission status needs to be determined, the received power on the temple side can be acquired; when only the data transmission status needs to be determined, the received signal strength on the temple side, the demodulation quality on the frame side, or the communication error rate can be acquired; when both the power transmission status and data transmission status need to be determined simultaneously, the corresponding parameters can be acquired separately in the power transmission time slot and the data transmission time slot. Thus, acquisition results characterizing the current transmission status of a single pair of coil transmission channels can be obtained.

[0075] 602. Determine the coupling state parameters between the first inductive coupling coil and the second inductive coupling coil based on the acquisition results; Based on the acquisition results, the coupling state parameters between the first and second inductive coupling coils are determined. These coupling state parameters characterize the strength of the coupling between the first and second inductive coupling coils in their current hinge opening / closing state, relative position state, or relative attitude state. The coupling state parameters can be quantitative or hierarchical; quantitative parameters represent the numerical value of the current coupling strength, while hierarchical parameters indicate whether the current coupling state is weakened, normal, or strengthened.

[0076] When determining the coupling state parameters, the received power on the temple side can be compared with a preset power range, the received signal strength on the temple side can be compared with a preset signal strength range, the demodulation quality on the frame side can be compared with a preset demodulation quality range, or the communication error rate can be compared with a preset error threshold. When the acquisition results show a decrease in received power, a decrease in received signal strength, a decrease in demodulation quality, or an increase in communication errors, it can be determined that the coupling state parameters represent a weakening of the coupling between the first inductive coupling coil and the second inductive coupling coil; when the acquisition results show an increase in received power, an increase in received signal strength, an improvement in demodulation quality, or a decrease in communication errors, it can be determined that the coupling state parameters represent an strengthening of the coupling between the first inductive coupling coil and the second inductive coupling coil.

[0077] 603. When the coupling state parameter indicates that the coupling between the first inductive coupling coil and the second inductive coupling coil is weakened, the carrier drive power in the power transmission time slot is increased, and / or the data transmission rate in the data transmission time slot is decreased. When the coupling state parameter indicates a weakening of the coupling between the first and second inductively coupled coils, it suggests a decrease in either the power transmission capability, data transmission capability, or both of the single-coil transmission channel under the current condition. In this case, the carrier drive power within the power transmission time slot can be increased to generate stronger inductive coupling excitation in the first inductively coupled coil, compensating for the impact of weakened coupling on the received power at the telescope's mounting side. Alternatively, the data transmission rate within the data transmission time slot can be reduced to provide a larger signal decision margin during data transmission, thereby mitigating the impact of weakened coupling on data demodulation and bit error rates.

[0078] Increasing carrier drive power and reducing data transmission rate can be performed selectively or simultaneously. For example, when weakened coupling is mainly manifested as insufficient receiving power on the telescope arm side, the carrier drive power in the power transmission time slot can be increased first; when weakened coupling is mainly manifested as increased communication errors or degraded demodulation quality, the data transmission rate in the data transmission time slot can be reduced first; when insufficient receiving power and degraded communication quality occur simultaneously, the carrier drive power in the power transmission time slot can be increased and the data transmission rate in the data transmission time slot can be reduced simultaneously.

[0079] 604. When the coupling state parameter characterizes the enhanced coupling between the first inductive coupling coil and the second inductive coupling coil, reduce the carrier drive power in the power transmission time slot and / or increase the data transmission rate in the data transmission time slot.

[0080] When the coupling state parameter characterizes the enhanced coupling between the first and second inductively coupled coils, it indicates that the single-coil transmission channel has good power transmission capability, data transmission capability, or one of both in the current state. At this time, the carrier drive power within the power transmission time slot can be reduced, allowing the temple side to still obtain sufficient receiving power while reducing unnecessary drive energy consumption; alternatively, the data transmission rate within the data transmission time slot can be increased, enabling the single-coil transmission channel to carry more data in a better coupling state, thus improving data transmission efficiency.

[0081] Reducing carrier drive power and increasing data transmission rate can be performed selectively or simultaneously. For example, when coupling enhancement is mainly manifested as the received power on the telescope side exceeding the required range, the carrier drive power in the power transmission time slot can be reduced first; when coupling enhancement is mainly manifested as good demodulation quality or low communication error rate, the data transmission rate in the data transmission time slot can be increased; when both sufficient received power and good communication quality occur simultaneously, the carrier drive power in the power transmission time slot and the data transmission rate in the data transmission time slot can be reduced and increased at the same time.

[0082] In this embodiment, parameters related to received power, received signal strength, demodulation quality, or communication errors are collected during the execution of the power transmission time slot and / or data transmission time slot. Based on these parameters, the coupling state parameters between the first and second inductive coupling coils are determined, allowing the carrier drive power and data transmission rate to be adjusted according to the coupling changes caused by the opening and closing of the hinge. When the coupling weakens, the carrier drive power is increased and / or the data transmission rate is decreased; when the coupling strengthens, the carrier drive power is decreased and / or the data transmission rate is increased. This helps to balance the received power on the temple side, communication error control, and energy consumption control, thereby improving the stability of power and data co-coil transmission of the smart glasses under different hinge postures.
