Description

Technical Field

[0001] This invention relates to the field of smart wearable devices and human-computer interaction technology, and in particular to a human-computer interaction control method and its intelligent control system based on behavioral intention perception. Background Technology

[0002] With the integration of artificial intelligence and the Internet of Things (IoT) technologies, wearable smart devices have become an important medium for human-computer interaction. However, in practical applications, especially in scenarios such as outdoor work, special vehicle driving, and winter sports, existing wearable devices still have significant shortcomings in their human-computer interaction methods: First, the start / stop control and mode switching of existing wearable devices heavily rely on users' physical button operations or touchscreen input. This interaction method not only occupies the user's visual attention and hand operation resources, but is also difficult to perform when the user's hands are occupied (such as holding tools, operating a steering wheel, ski poles) or wearing heavy protective gear. This violates the principles of naturalness, efficiency, and non-intrusion pursued in human-computer interaction, lacks the ability to proactively perceive and predict the user's behavioral intentions, and causes the device to be in a "passive response" state.

[0003] Secondly, existing wearable devices have weak motion recognition and behavior monitoring capabilities. The system cannot autonomously determine whether a user is in a "high-activity working state," a "static insulation state," or a "device detached (offline) state." This "interaction deafness" prevents the device from dynamically adjusting its operating mode based on the user's real-time behavior, resulting in energy waste, delayed response, and even continued high-power operation after the user stops activity, posing safety hazards.

[0004] Third, existing systems lack a refined feedback adjustment mechanism based on user behavior. Different areas of the human hand (such as the back of the hand and fingertips) consume and require different amounts of heat during activity, but existing devices mostly heat only one area or have simple on / off control. They cannot provide differentiated dynamic heat compensation based on user behavior patterns (such as clenching a fist, extending, or grasping), resulting in a poor user experience and failing to achieve the optimal match between energy supply and the actual needs of the human body.

[0005] Therefore, there is an urgent need for a wearable human-computer interaction control system that can perceive the user's wearing status and behavioral intentions in real time through non-contact sensor networks, and has intelligent behavior recognition and adaptive response capabilities, so as to realize the leap of the device from "passive response to operation" to "active understanding of user intentions". Summary of the Invention

[0006] The technical problem this invention aims to solve is to overcome the shortcomings of existing technologies and provide a human-computer interaction control method and its intelligent control system based on behavioral intent perception. This addresses issues in existing heated gloves, such as the susceptibility to low temperatures, humidity, and repeated pressing leading to insufficient reliability of start-stop, the tendency to forget to disconnect power after removal, coarse control of the heating area, unintuitive battery status, and unstable battery life due to continuous high-power operation. Simultaneously, it enables the device to perceive and autonomously respond to the user's wearing intent without physical contact, improving the naturalness and convenience of human-computer interaction.

[0007] To achieve the aforementioned objectives, the first aspect of this invention provides a human-computer interaction control method based on behavioral intent perception, applied to an intelligent control system for heated gloves, comprising the following steps: The Hall magnetic induction switch module detects the change in magnetic induction intensity caused by the user's closing action when wearing the garment in a non-contact manner, and generates a wear status signal. The central control chip compares the wearable status signal with a preset first authorization threshold and a second disconnection threshold, wherein the first authorization threshold is greater than the second disconnection threshold; When the magnetic induction intensity signal is greater than the first authorized threshold, the central control chip allows the PWM power adjustment unit to output heating power to the partitioned flexible heating module; when the magnetic induction intensity signal is less than the second disconnection threshold, the central control chip controls the PWM power adjustment unit to stop outputting heating power to the partitioned flexible heating module. During the heating process, the central control chip independently adjusts the PWM output duty cycle of the flexible heating pads in the finger area, palm area, and back of hand area based on the zone temperature information collected by multiple temperature sensors. The central control chip records the continuous working time in the wearable authorized state through the timing unit. When the continuous working time reaches the preset sleep time, the PWM power adjustment unit is controlled to reduce or suspend the heating output to enter the sleep energy-saving state. In the sleep energy-saving state, the temperature signals of each temperature sensor are continuously monitored. When the temperature fluctuation of any heating zone reaches the preset wake-up temperature difference, the heating output is restored.

[0008] Optionally, the method further includes: the central control chip controlling the RGB three-color LED indicator to display different colors according to the lithium battery power range detected by the power detection unit; when the lithium battery power is lower than the safety threshold, reducing the maximum output duty cycle of the PWM power adjustment unit or stopping the heating output.

[0009] A second aspect of this invention provides a human-computer interaction intelligent control system based on behavioral intent perception, applied to heated gloves, which has intelligent sensing and adaptive heating control functions, including: The glove body includes a waterproof and abrasion-resistant outer layer, a skin-friendly and heat-insulating inner layer, and a heating interlayer disposed between the waterproof and abrasion-resistant outer layer and the skin-friendly and heat-insulating inner layer; The glove body includes a Hall magnetic induction switch module located on the wrist, a partitioned flexible heating module located in the heating interlayer, multiple temperature sensors corresponding to the partitioned flexible heating module, a constant temperature sleep control module located on the wrist, a power detection unit, an RGB three-color LED indicator, a lithium battery, a Type-C fast charging interface, and a charging management circuit located between the Type-C fast charging interface and the lithium battery. The charging management circuit includes an overcharge protection circuit, an over-discharge protection circuit, an overcurrent protection circuit, and a temperature protection circuit. The Hall magnetic induction switch module includes a Hall sensor, a permanent magnet induction element and a signal processing unit, which is used to detect changes in magnetic induction intensity caused by the user's closing action of wearing the device in a non-contact manner and generate a wear status signal. The partitioned flexible heating module includes a flexible heating pad for the finger area, a flexible heating pad for the palm area, and a flexible heating pad for the back of the hand area. The constant temperature sleep control module includes a central control chip, a PWM power adjustment unit, a timing unit, and a sleep trigger circuit; The Hall sensor, the signal processing unit, the temperature sensor, the PWM power adjustment unit, the timing unit, the sleep trigger circuit, the power detection unit, and the RGB tri-color LED indicator are all electrically connected to the central control chip. The central control chip has a built-in behavior intention recognition program. By executing instructions stored in non-volatile memory, it performs multi-source information fusion and comprehensive judgment on Hall sensor signals, temperature sensor signals, power detection signals and timing unit signals, and outputs PWM control signals to each zone of flexible heating element to autonomously decide on the power-on, power-off, power adjustment and sleep wake-up of the heating system.

[0010] Optionally, the Hall sensor is disposed on one side of the wrist, and the permanent magnet induction element is disposed on the opposite side of the wrist or at the wristband buckle end, so that when the glove body is in the wearing closed state, the permanent magnet induction element approaches the Hall sensor and forms a magnetic induction trigger state; the signal processing unit is used to filter, shape and threshold the magnetic induction intensity signal output by the Hall sensor, and send the processed wearing state signal to the central control chip.

[0011] Optionally, the central control chip is configured to: allow the PWM power adjustment unit to output heating power to the partitioned flexible heating module when the magnetic induction intensity signal is greater than the first authorized threshold; and stop the PWM power adjustment unit from outputting heating power to the partitioned flexible heating module when the magnetic induction intensity signal is less than the second disconnection threshold, wherein the first authorized threshold is greater than the second disconnection threshold, forming a hysteresis interval for magnetic induction judgment.

[0012] Optionally, the flexible heating pads in the finger area are arranged in segments along the knuckle direction of the fingers, forming a flexible transition area between adjacent segments; the flexible heating pads in the palm area are arranged around the outer edge of the palm bearing area; and the flexible heating pads in the back of the hand area cover the heat dissipation area of ​​the back of the hand.

[0013] Optionally, the plurality of temperature sensors are respectively set for the flexible heating pads in the finger area, the palm area, and the back of the hand area. The central control chip independently controls the PWM output duty cycle of the flexible heating pads in the finger area, the palm area, and the back of the hand area based on the zone temperature information collected by the plurality of temperature sensors.

[0014] Optionally, the timing unit is used to record the continuous working time of the glove body in the wear authorization state, and the sleep trigger circuit is used to output a sleep trigger signal to the central control chip when the continuous working time reaches a preset sleep time; after receiving the sleep trigger signal, the central control chip controls the PWM power adjustment unit to reduce or suspend the heating output to the partition flexible heating module and enter the sleep energy-saving state.

[0015] Optionally, in the sleep energy-saving state, the central control chip continuously acquires the temperature signal from the temperature sensor, and when any temperature sensor detects that the temperature fluctuation of the corresponding heating zone reaches the preset wake-up temperature difference, it controls the PWM power regulation unit to resume heating output.

[0016] Optionally, the power detection unit is electrically connected to the lithium battery, and the central control chip controls the RGB tri-color LED indicator to display different colors according to the power range detected by the power detection unit. When the power of the lithium battery is lower than the safety threshold, the chip reduces the maximum output duty cycle of the PWM power adjustment unit or stops the heating output.

[0017] The beneficial effects of this invention are: 1. This invention constructs a non-contact behavioral intent perception and proactive response interaction mechanism, significantly improving the naturalness and convenience of human-computer interaction in wearable devices. This invention abandons traditional mechanical buttons or touch switches that rely on physical contact. Through the cooperation of Hall sensors and permanent magnet induction components, it achieves non-contact perception of the user's "preparing to wear" or "completing wearing" behavioral intent. The central control chip autonomously decides whether to power on or off the heating system based on the comparison between the magnetic induction intensity and a preset threshold, without requiring manual operation by the user. This design enables the device to "proactively understand" the user's intent, effectively freeing the user's hands, and is particularly suitable for interaction scenarios where hands are occupied (such as driving or holding tools), significantly improving the human-computer interaction efficiency of wearable devices in complex working conditions.

[0018] 2. This invention achieves intelligent fusion and collaborative decision-making of multi-source heterogeneous sensing signals, improving the environmental adaptability and decision-making accuracy of the interactive system. This invention uses a central control chip to centrally process and comprehensively judge the wearer status signal (user intent) acquired by the Hall magnetic induction switch module, the zoned temperature feedback signal (thermal state) acquired by the temperature sensor, the continuous working timing signal (behavior duration) acquired by the timing unit, and the energy status signal acquired by the power detection unit. This multi-source information linkage mechanism enables the device to adaptively switch working modes (normal heating, fine power adjustment, hibernation standby, low power) under different states (wearing authorization, temperature met, timeout standby, low power), realizing a complete intelligent control process from environmental and status perception to adaptive adjustment at the execution end.

[0019] 3. This invention achieves intelligent sleep and precise wake-up through behavioral timing analysis, demonstrating continuous tracking of user intent. The invention records the duration of the user's "wearable authorized state" using a timing unit, which serves as the basis for determining whether the user is in a state of "prolonged inactivity" or "forgotten offline." When continuous working time exceeds the limit, the system automatically enters a low-power sleep mode, avoiding unnecessary energy consumption. Simultaneously, during sleep, the system continues to monitor temperature sensor signals, using "temperature fluctuations in any heating zone" as a wake-up source. This allows for sensitive perception of the user's intention to resume activity (such as changes in heat caused by limb movement), thereby accurately restoring heating output and achieving dynamic adaptation of the device to changes in user behavior.

[0020] 4. This invention addresses the differentiated thermal needs of different areas of the human hand by employing ergonomic, zoned, and refined thermal management. Recognizing the significant differences in physiological structure and heat dissipation characteristics among the fingers, palm, and back of the hand, three independent flexible heating elements are designed for each area: the finger area, the palm area, and the back of the hand. Each element is equipped with its own independent temperature sensor and PWM power adjustment channel. The central control chip independently adjusts the heating power of each area based on real-time temperature feedback. This zoned, differentiated control method, compared to single-area heating, more effectively meets the varying thermal needs of different parts of the hand during actual use (e.g., pressure on the palm during gripping, and fingertips easily cooling), significantly improving heat utilization efficiency and user comfort.

[0021] 5. This invention integrates visualized energy status interaction with low-battery autonomous protection, improving the transparency of information in human-computer interaction. The invention monitors the remaining lithium battery power in real time through a power detection unit and provides intuitive and visualized power status feedback to the user via RGB tri-color LED indicators, improving the transparency of information in human-computer interaction. More importantly, when the battery level falls below a safe threshold, the system does not simply shut down. Instead, it autonomously and smoothly reduces the maximum output duty cycle of the PWM power regulation unit based on the remaining energy status, achieving intelligent extension of battery life and effective avoidance of battery over-discharge risks, thus improving the safety and reliability of the device throughout its entire lifecycle.

[0024] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0025] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0026] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0027] like Figures 1 to 6 As shown, this embodiment provides a human-computer interaction intelligent control system based on behavioral intent perception, applied to a heated glove, which has intelligent sensing and adaptive heating control functions, including a glove body 1. The glove body 1 includes a waterproof and wear-resistant outer layer 2, a skin-friendly and heat-insulating inner layer 3, and a heating interlayer 4 disposed between the waterproof and wear-resistant outer layer 2 and the skin-friendly and heat-insulating inner layer 3. The wrist 5 of the glove body 1 is provided with a Hall magnetic induction switch module 6, a constant temperature sleep control module 9, a power detection unit 10, an RGB three-color LED indicator 11, a lithium battery 12, and a Type-C fast charging interface 13. The heating interlayer 4 is provided with a partitioned flexible heating module 7, and multiple temperature sensors 8 are provided corresponding to the partitioned flexible heating module 7.

[0028] The waterproof and abrasion-resistant outer layer 2 is used to resist rain, snow, friction, and low-temperature environments, and can be made of TPU composite fabric, nylon fabric, polyester Oxford cloth, or other flexible materials with waterproof and abrasion-resistant properties. The skin-friendly and heat-insulating inner layer 3 is used to contact the user's hands and retain heat, and can be made of fleece, polar fleece, thermal insulation cotton, or other soft insulation materials. The heating interlayer 4 is located between the waterproof and abrasion-resistant outer layer 2 and the skin-friendly and heat-insulating inner layer 3, and is used to accommodate the partitioned flexible heating module 7, temperature sensor 8, and related flexible wires.

[0029] The Hall magnetic induction switch module 6 is used to identify whether the glove body 1 is in the wearing closed state. The constant temperature sleep control module 9 is used to control the heating output according to the wearing state, zone temperature, continuous working time and power status. The power detection unit 10 is used to detect the power status of the lithium battery 12. The RGB three-color LED indicator 11 is used to display different power ranges. The Type-C fast charging interface 13 is used to connect to an external charging power source. The lithium battery 12 is used to provide power to various electrical components.

[0030] like Figure 3 As shown, the Hall magnetic induction switch module 6 includes a Hall sensor 61, a permanent magnet induction element 62, and a signal processing unit 63. The Hall sensor 61 is disposed on one side of the wrist 5, and the permanent magnet induction element 62 is disposed on the opposite side of the wrist 5 or at the wristband fastening end. When the user wears gloves and closes the wrist 5 in place, the permanent magnet induction element 62 approaches the Hall sensor 61, and the Hall sensor 61 detects the change in magnetic induction intensity and outputs a magnetic induction intensity signal.

[0031] The signal processing unit 63 is electrically connected to the Hall sensor 61 and the central control chip 91. The signal processing unit 63 is used to filter, shape and threshold the magnetic induction intensity signal output by the Hall sensor 61 to suppress false triggering caused by wrist swaying, short-term magnetic field disturbance or slight changes in wearing position, and sends the processed wearing status signal to the central control chip 91.

[0032] The central control chip 91 is used to: determine that the glove body 1 is in a wear authorization state when the magnetic induction intensity signal is greater than the first authorization threshold, and allow the PWM power adjustment unit 92 to output heating power to the partitioned flexible heating module 7; and determine that the glove body 1 is not in a wear authorization state when the magnetic induction intensity signal is less than the second disconnection threshold, and stop the PWM power adjustment unit 92 from outputting heating power to the partitioned flexible heating module 7. The first authorization threshold is greater than the second disconnection threshold, thereby forming a hysteresis interval for magnetic induction judgment, reducing frequent start-stops caused by slight relative movement between the permanent magnet induction element 62 and the Hall sensor 61 near the critical distance.

[0033] In a preferred embodiment, the effective sensing distance between the Hall sensor 61 and the permanent magnet induction element 62 is 3mm to 8mm. When the effective sensing distance is less than 3mm, the accuracy requirement for the wrist 5 closing position is high, which may reduce the tolerance for wearing errors; when the effective sensing distance is greater than 8mm, the probability of false triggering in the non-closed state may increase. Setting the effective sensing distance to 3mm to 8mm can balance the reliability of wrist 5 closing recognition and wearing comfort.

[0034] In another preferred embodiment, a mounting compensation angle of 15° to 35° is formed between the sensitive surface of the Hall sensor 61 and the magnetic pole direction of the permanent magnet induction element 62 to accommodate changes in the magnetic field direction caused by wrist bending, wrist swinging, and slight shifts in wearing position. Setting the mounting compensation angle within the above range is beneficial for improving the stability of magnetic induction recognition.

[0035] like Figure 4 , Figure 5 As shown, the partitioned flexible heating module 7 is disposed in the heating interlayer 4, including a flexible heating sheet 71 for the finger area, a flexible heating sheet 72 for the palm area, and a flexible heating sheet 73 for the back of the hand area.

[0036] Flexible heating pads 71 ​​in the finger area are arranged in segments along the knuckles of the fingers. Flexible transition areas can be formed between adjacent segments to accommodate finger bending movements and reduce bending fatigue of the heating pads at the knuckles. Flexible heating pads 72 in the palm area are arranged around the outer edge of the palm's pressure-bearing area, avoiding the main pressure areas when gripping tools, handlebars, or ski poles, reducing the risk of damage to the heating pads due to prolonged pressure. Flexible heating pads 73 in the back of the hand area cover the heat dissipation area of ​​the back of the hand to compensate for planar heat loss in low-temperature environments.

[0037] Multiple temperature sensors 8 are respectively positioned corresponding to the flexible heating pad 71 in the finger area, the flexible heating pad 72 in the palm area, and the flexible heating pad 73 in the back of the hand area. The temperature sensors 8 can be NTC thermistors, digital temperature sensors, or flexible temperature sensing elements. Preferably, the temperature sensors 8 are positioned close to the skin-friendly heat-insulating inner layer 3, so that the temperature collected by the temperature sensors 8 is closer to the temperature perceived by the user's hand.

[0038] The central control chip 91 controls the PWM output duty cycle of the flexible heating element 71 in the finger area, the flexible heating element 72 in the palm area, and the flexible heating element 73 in the back of the hand area based on the zone temperature information collected by multiple temperature sensors 8. When the temperature of a certain heating zone is lower than the corresponding preset temperature, the central control chip 91 increases the PWM output duty cycle of the corresponding heating zone; when the temperature of a certain heating zone reaches or exceeds the corresponding preset temperature, the central control chip 91 decreases the PWM output duty cycle of the corresponding heating zone or pauses the heating output of the heating zone.

[0039] In a preferred embodiment, a flexible buffer gap is provided between adjacent flexible heating elements, with a width of 2mm to 6mm. This flexible buffer gap provides deformation space for hand bending and gripping movements, reducing stress concentration at the edges of the flexible heating elements. When the flexible buffer gap is less than 2mm, the buffering effect is insufficient; when it is greater than 6mm, it may affect the continuity of heating coverage. Therefore, setting the flexible buffer gap to 2mm to 6mm balances flexibility and heating coverage.

[0040] In an alternative embodiment, the flexible heating element 71 in the finger area uses a flexible conductive fiber heating layer, the flexible heating element 72 in the palm area uses a carbon fiber heating layer, and the flexible heating element 73 in the back of the hand area uses a graphene composite heating film. The flexible conductive fiber heating layer is suitable for high-frequency bending in the finger area, the carbon fiber heating layer is suitable for pressure conditions in the palm area, and the graphene composite heating film is suitable for planar heat dissipation compensation in the back of the hand area. The above materials can be replaced with equivalent materials according to the actual application scenario, as long as the flexible heating function of the corresponding heating zone can be achieved.

[0041] like Figure 6 As shown, the constant temperature sleep control module 9 includes a central control chip 91, a PWM power adjustment unit 92, a timing unit 93, and a sleep trigger circuit 94. The Hall sensor 61, signal processing unit 63, temperature sensor 8, PWM power adjustment unit 92, timing unit 93, sleep trigger circuit 94, power detection unit 10, and RGB tri-color LED indicator 11 are all electrically connected to the central control chip 91.

[0042] The central control chip 91 has a built-in behavior intention recognition program. By executing instructions stored in non-volatile memory, it performs multi-source information fusion and comprehensive judgment on Hall sensor signals, temperature sensor signals, power detection signals and timing unit signals, and outputs PWM control signals to each zone of flexible heating element to autonomously decide on the power-on, power-off, power adjustment and sleep wake-up of the heating system.

[0043] The PWM power adjustment unit 92 adjusts the heating power of the flexible heating sheet 71 in the finger area, the flexible heating sheet 72 in the palm area, and the flexible heating sheet 73 in the back of the hand area according to the PWM control signal output by the central control chip 91.

[0044] The timing unit 93 records the continuous working time of the glove body 1 while it is in the authorized wearing state. The sleep trigger circuit 94 outputs a sleep trigger signal to the central control chip 91 when the continuous working time reaches the preset sleep time. After receiving the sleep trigger signal, the central control chip 91 controls the PWM power adjustment unit 92 to reduce or pause the heating output to the partitioned flexible heating module 7, so that the heated glove enters a sleep energy-saving state.

[0045] In sleep-and-energy-saving mode, the central control chip 91 continues to monitor the Hall sensor 61 and the temperature sensor 8. When any temperature sensor 8 detects that the temperature fluctuation of the corresponding heating zone reaches the preset wake-up temperature difference, the central control chip 91 controls the PWM power regulation unit 92 to resume heating output to the corresponding heating zone or all heating zones.

[0046] In one implementation, the preset sleep time is 10 minutes, and the preset wake-up temperature difference is 2°C. In another implementation, the preset sleep time can be set to 5 minutes, 15 minutes, or 30 minutes, and the preset wake-up temperature difference can be set to 1°C, 3°C, or 5°C. A shorter preset sleep time improves energy efficiency; a longer preset sleep time helps maintain continuous heat preservation. A smaller preset wake-up temperature difference allows for more timely resumption of heating; a larger preset wake-up temperature difference reduces power consumption fluctuations caused by frequent wake-ups. These parameters can be set according to the usage scenario, ambient temperature, and battery capacity.

[0047] The power detection unit 10 is electrically connected to the lithium battery 12 and is used to detect the remaining power, voltage, or capacity status of the lithium battery 12. The RGB tri-color LED indicator 11 is located on the surface of the wrist 5 and is electrically connected to the central control chip 91, allowing the user to observe the power status while wearing the device.

[0048] The central control chip 91 controls the RGB tri-color LED indicator 11 to display different colors based on the power range detected by the power detection unit 10. For example, when the power is in the high range, the RGB tri-color LED indicator 11 displays green; when the power is in the medium range, the RGB tri-color LED indicator 11 displays blue or yellow; and when the power is in the low range, the RGB tri-color LED indicator 11 displays red. The correspondence between the above colors and power ranges can be adjusted according to the product design, as long as different colors can distinguish different power states.

[0049] When the lithium battery 12's charge level falls below a safe threshold, the central control chip 91 reduces the maximum output duty cycle of the PWM power regulation unit 92 or stops the heating output, and provides a low-charge warning via the RGB tri-color LED indicator 11. This setting reduces the risk of over-discharge of the lithium battery 12 and avoids increased battery burden caused by continuous high-power output when the battery is low.

[0050] The lithium battery 12 is located inside the wrist 5 and is used to supply power to the central control chip 91, Hall sensor 61, signal processing unit 63, temperature sensor 8, PWM power adjustment unit 92, timing unit 93, sleep trigger circuit 94, power detection unit 10, RGB three-color LED indicator 11 and zoned flexible heating module 7.

[0051] The Type-C fast charging port 13 is located on the wrist 5 and is connected to the lithium battery 12 via the charging management circuit 14. The charging management circuit 14 includes an overcharge protection circuit 141, an over-discharge protection circuit 142, an overcurrent protection circuit 143, and a temperature protection circuit 144.

[0052] During charging, the overcharge protection circuit 141 limits or stops charging when the charging voltage or state of charge of the lithium battery 12 reaches a set protection condition; the over-discharge protection circuit 142 limits or cuts off discharge when the discharge voltage of the lithium battery 12 is lower than a set protection condition; the overcurrent protection circuit 143 limits or cuts off the current path when the charging or discharging current exceeds a set protection condition; and the temperature protection circuit 144 limits or cuts off the charging and discharging process when the temperature of the lithium battery 12 or the charging management circuit 14 is abnormal. Through the coordinated operation of these protection circuits, the safety of the lithium battery 12 in charging, discharging, and low-temperature operating environments can be improved.

[0053] The working principle of this embodiment is as follows: After the user puts on the gloves and closes the wrist 5, the permanent magnet induction element 62 approaches the Hall sensor 61. The Hall sensor 61 detects the change in magnetic field and outputs a magnetic induction intensity signal. The signal processing unit 63 filters, shapes, and performs threshold judgment on the magnetic induction intensity signal, and then sends the wearing status signal to the central control chip 91.

[0054] The central control chip 91 compares the processed magnetic induction intensity signal with the first authorized threshold. When the magnetic induction intensity signal is greater than the first authorized threshold, the central control chip 91 determines that the glove body 1 is in the wearing authorized state and allows the PWM power adjustment unit 92 to output heating power to the flexible heating sheet 71 in the finger area, the flexible heating sheet 72 in the palm area, and the flexible heating sheet 73 in the back of the hand area.

[0055] During the heating process, multiple temperature sensors 8 detect the temperature of their respective heating zones and send the zone temperature information to the central control chip 91. The central control chip 91 adjusts the duty cycle of the corresponding PWM output based on the temperature feedback from each heating zone, ensuring that the finger area, palm area, and back of the hand area are maintained within a preset constant temperature range according to their respective heat dissipation characteristics. Thus, the finger area can provide heating compensation for easily cooled extremities, the palm area can avoid major load-bearing areas to reduce the risk of pressure injury, and the back of the hand area can cover the heat dissipation area to compensate for surface heat loss.

[0056] When the user removes the glove or the wrist 5 is not fully closed, the permanent magnet induction element 62 moves away from the Hall sensor 61, and the magnetic induction intensity signal output by the Hall sensor 61 decreases. When the magnetic induction intensity signal is less than the second disconnection threshold, the central control chip 91 determines that the glove body 1 is not in a wearing authorization state and controls the PWM power adjustment unit 92 to stop outputting heating power to the partitioned flexible heating module 7. Since the first authorization threshold is greater than the second disconnection threshold, the central control chip 91 can form hysteresis control between wearing authorization and disconnection judgment, reducing frequent start-stop caused by slight shaking of the wrist 5.

[0057] When the glove body 1 is in the authorized wearing state and has been working continuously for a preset sleep time, the timing unit 93 and the sleep trigger circuit 94 cooperate to output a sleep trigger signal to the central control chip 91. After receiving the sleep trigger signal, the central control chip 91 controls the PWM power adjustment unit 92 to reduce or pause the heating output to the partitioned flexible heating module 7, causing the glove to enter a sleep energy-saving state. In the sleep energy-saving state, the central control chip 91 continues to acquire the temperature signal from the temperature sensor 8. When any temperature sensor 8 detects that the temperature fluctuation of the corresponding heating partition reaches the preset wake-up temperature difference, the central control chip 91 controls the PWM power adjustment unit 92 to resume the heating output, thereby maintaining the necessary heat preservation capacity while reducing ineffective power consumption.

[0058] The power detection unit 10 monitors the power status of the lithium battery 12 in real time or periodically and sends the power detection signal to the central control chip 91. The central control chip 91 controls the RGB tri-color LED indicator 11 to display different colors according to the power range to indicate the current remaining power to the user. When the power of the lithium battery 12 is lower than the safety threshold, the central control chip 91 reduces the maximum output duty cycle of the PWM power regulation unit 92 or stops the heating output to reduce the risk of over-discharge of the lithium battery 12.

[0059] When an external power source is connected via the Type-C fast charging interface 13, the charging management circuit 14 manages the charging of the lithium battery 12. The overcharge protection circuit 141, over-discharge protection circuit 142, overcurrent protection circuit 143, and temperature protection circuit 144 respectively protect the charging and discharging voltage, current, and temperature status to improve the charging and discharging safety of the heated gloves.

[0060] Without departing from the concept of this invention, the Hall sensor 61 can be a unipolar Hall switch, a bipolar Hall switch, a linear Hall sensor, or other magnetic sensing devices capable of detecting changes in the magnetic field. The permanent magnet sensing element 62 can be a neodymium iron boron magnet, a ferrite magnet, or other permanent magnet materials capable of providing a stable magnetic field.

[0061] Without affecting the power display function, the RGB tri-color LED indicator 11 can use a single RGB LED, a combination of multiple monochrome LEDs, or a light strip structure with multi-color display capabilities. The correspondence between power ranges and display colors can be set according to the application scenario.

[0062] Without affecting the sleep energy-saving control function, the preset sleep time, preset wake-up temperature difference, first authorization threshold, second disconnection threshold, and safety threshold can all be set according to different battery capacities, different usage scenarios, different ambient temperatures, and different heating power levels.

[0063] In summary, this implementation method constructs a complete human-computer interaction closed loop of "perception → recognition → decision-making → execution → feedback": using a Hall magnetic induction switch module as a non-contact intention perception entry point, a central control chip as the core of multi-source signal fusion and autonomous decision-making, a zoned flexible heating module as a refined execution terminal, RGB three-color LED indicator as a status feedback output terminal, and a timing and sleep circuit as a behavior status tracking and proactive adaptation mechanism, thereby enabling the device to leap from "passively responding to operations" to "actively understanding user behavior intentions".

[0064] As an embodiment of the human-computer interaction control method based on behavioral intention perception of the present invention, the following is combined with Figures 1 to 6 The system structure shown illustrates the implementation details of the control method. This method can be applied to the intelligent control systems described in the above embodiments, where the central control chip 91 executes behavioral intent recognition program instructions stored in non-volatile memory to achieve autonomous decision-making and adaptive control of the heated glove heating system.

[0065] The control method in this embodiment includes the following steps: Step S1: Non-contact sensing and generation of wear status signals. The wear status signal is generated by non-contact detection of the change in magnetic induction intensity caused by the user's closing action of wearing the device through the Hall magnetic induction switch module 6.

[0066] Specifically, when the user puts on the gloves and closes the wrist 5, the Hall sensor 61 located on one side of the wrist 5 approaches the permanent magnet induction element 62 located on the opposite side of the wrist 5 or at the buckle end of the wristband. The Hall sensor 61 detects the change in magnetic induction intensity and outputs a corresponding analog or digital signal of magnetic induction intensity. The signal processing unit 63 filters (e.g., low-pass filtering to remove high-frequency noise), shapes (e.g., a comparator to shape into a square wave signal), and performs threshold judgment (e.g., preliminary screening of the effective signal range) on the signal to suppress false triggering caused by wrist shaking, short-term magnetic field disturbances, or slight changes in wearing position, and sends the processed wearing status signal to the central control chip 91.

[0067] If the Hall sensor 61 does not detect a sufficient change in magnetic induction intensity (e.g., the user is not wearing gloves or the wrist is not closed properly), the central control chip 91 determines that the current state is an unauthorized wearable state and does not start the heating output.

[0068] Step S2: Threshold comparison of wearable status signal and heating authorization decision. The central control chip 91 compares the wearable status signal with a preset first authorization threshold and a second disconnection threshold. The first authorization threshold is greater than the second disconnection threshold.

[0069] Specifically, the central control chip 91 internally stores a first authorization threshold (e.g., the magnetic induction intensity value corresponding to an effective sensing distance of 8mm between the Hall sensor 61 and the permanent magnet induction element 62) and a second disconnection threshold (e.g., the magnetic induction intensity value corresponding to an effective sensing distance of 10mm). A hysteresis interval is formed between the two thresholds to avoid frequent start-stop due to wrist micro-movements.

[0070] The central control chip 91 compares the real-time received magnetic induction intensity signal value with the two thresholds mentioned above to determine the current range of the magnetic induction intensity signal.

[0071] Step S3: Based on the threshold comparison result, the heating is powered on or off. When the magnetic induction intensity signal is greater than the first authorized threshold (i.e., the user's gloves are closed in place), the central control chip 91 allows the PWM power adjustment unit 92 to output heating power to the partitioned flexible heating module 7. When the magnetic induction intensity signal is less than the second disconnection threshold (i.e., the user takes off the gloves or the wrist is not closed in place), the central control chip 91 controls the PWM power adjustment unit 92 to stop outputting heating power to the partitioned flexible heating module 7.

[0072] In this step, since the first authorization threshold is greater than the second disconnection threshold, when the magnetic induction intensity signal is in the hysteresis interval between the first authorization threshold and the second disconnection threshold, the central control chip 91 maintains the current heating output state unchanged—that is, if it is currently in a heating state, it continues to heat; if it is currently in a stopped state, it remains stopped. This hysteresis control mechanism can effectively avoid the system frequently switching between the "authorized" and "disconnected" states when the permanent magnet inductor 62 and the Hall sensor 61 are near the critical distance and there is a slight relative displacement due to normal user activity (such as a slight wrist movement), thereby improving the stability of control and the user experience.

[0073] Step S4: Zoned temperature acquisition and independent PWM control during the heating process. During the heating process, the central control chip 91 independently adjusts the PWM output duty cycle of the flexible heating sheet 71 in the finger area, the flexible heating sheet 72 in the palm area, and the flexible heating sheet 73 in the back of the hand area based on the zoned temperature information collected by multiple temperature sensors 8.

[0074] Specifically, each temperature sensor 8 is positioned near the flexible heating pads in the finger area, palm area, and back of the hand area, respectively, and close to the skin-friendly heat-insulating inner layer 3, in order to collect temperature values ​​that are closer to the actual temperature perceived by the user's hand. Each temperature sensor 8 sends the collected zone temperature information to the central control chip 91 in real time.

[0075] The central control chip 91 compares the temperature of each zone with the preset target temperature value for the corresponding zone: When the current temperature of a certain heating zone is lower than the preset temperature corresponding to that zone, the central control chip 91 increases the duty cycle of the PWM output corresponding to that heating zone to increase the heating power; When the current temperature of a certain heating zone reaches or exceeds the preset temperature corresponding to that zone, the central control chip 91 reduces the duty cycle of the PWM output corresponding to that heating zone or pauses the heating output of that heating zone.

[0076] The preset temperature values ​​for each zone can be the same (e.g., uniformly set to 45℃), or they can be set differently according to the heat dissipation characteristics of different zones and the user's perception sensitivity (e.g., preset 48℃ for the finger area, 43℃ for the palm area, and 46℃ for the back of the hand area) to adapt to the different thermal needs of different areas under different action modes such as gripping and stretching. The temperature of each zone is controlled independently and does not interfere with each other.

[0077] Step S5: Monitoring the continuous working time and sleep decision of the wearable authorized state. The central control chip 91 records the continuous working time in the wearable authorized state through the timing unit 93. When the continuous working time reaches the preset sleep time, the PWM power adjustment unit 92 is controlled to reduce or suspend the heating output to enter the sleep energy-saving state.

[0078] Specifically, in step S3, when the central control chip 91 determines that the magnetic induction intensity signal is greater than the first authorized threshold and starts heating output, it triggers the timing unit 93 to start timing. The timing unit 93 continuously records the continuous working time of the glove body 1 in the authorized wearing state.

[0079] When the continuous working time recorded by the timing unit 93 reaches the preset sleep time (e.g., 10 minutes), the sleep trigger circuit 94 outputs a sleep trigger signal to the central control chip 91. After receiving the signal, the central control chip 91 controls the PWM power adjustment unit 92 to reduce the PWM output duty cycle of the partitioned flexible heating module 7 (e.g., reduce it to 50% of the normal operating duty cycle) or completely stop the heating output, so that the heated glove enters a sleep energy-saving state.

[0080] This step is designed based on continuous tracking of user behavior intentions: when the user has not performed any significant activities for a long time (as evidenced by a stable temperature distribution inside the glove with no obvious thermal fluctuations), the system determines that the user may be in a static state or has forgotten to go offline, and actively reduces power consumption to avoid energy waste.

[0081] Step S6: Temperature fluctuation monitoring and precise wake-up in sleep mode. In the sleep energy-saving state, the temperature signals of each temperature sensor 8 are continuously monitored. When the temperature fluctuation of any heating zone reaches the preset wake-up temperature difference, the heating output is restored.

[0082] Specifically, in the sleep-and-energy-saving state, the central control chip 91 pauses or reduces the heating power output, but still maintains signal reception and monitoring of each temperature sensor 8. The central control chip 91 calculates the temperature fluctuation of each heating zone by performing a difference calculation between the real-time temperature values ​​collected by each temperature sensor 8 and the temperature values ​​of each sensor at the moment of entering sleep mode.

[0083] When any temperature sensor 8 detects that the temperature fluctuation of the corresponding heating zone reaches or exceeds the preset wake-up temperature difference (e.g., 2°C), the central control chip 91 determines that the user has resumed activity (e.g., limb movement causing changes in air convection inside the glove, or the heat redistribution caused by the compression of the insulation layer due to the hand applying force again). At this time, the central control chip 91 controls the PWM power adjustment unit 92 to resume the heating output to the corresponding heating zone or all heating zones, so that the glove re-enters the normal heating working state.

[0084] If, during the hibernation period, the temperature fluctuations detected by all temperature sensors 8 do not reach the preset wake-up temperature difference, the system will continue to maintain the hibernation energy-saving state until the magnetic induction intensity signal indicates that the user is offline (less than the second disconnection threshold) or the temperature fluctuation triggers a wake-up.

[0085] Step S7 (optional): Battery status detection and visual prompts, and low battery protection.

[0086] As a preferred extension of the above control method, the central control chip 91 controls the RGB three-color LED indicator 11 to display different colors according to the power range of the lithium battery 12 detected by the power detection unit 10; when the power of the lithium battery 12 is lower than the safety threshold, the maximum output duty cycle of the PWM power adjustment unit 92 is reduced or the heating output is stopped.

[0087] Specifically, the power detection unit 10 detects the remaining power of the lithium battery 12 in real time or periodically and sends the power signal to the central control chip 91. The central control chip 91 compares the detected power value with preset power ranges. When the battery level is in a high range (e.g., remaining battery level ≥ 60%), the RGB tri-color LED indicator 11 will display green. When the battery level is in the middle range (e.g., 30% ≤ remaining battery < 60%), the RGB tri-color LED indicator 11 will display either blue or yellow. When the battery level is low (e.g., 10% ≤ remaining battery < 30%), the RGB tri-color LED indicator 11 will display red.

[0088] When the lithium battery 12's charge level is below a safety threshold (e.g., remaining charge <10%), the central control chip 91 reduces the maximum output duty cycle of the PWM power regulation unit 92 (e.g., limiting the maximum duty cycle to 50% of the normal value) to extend the battery life. When the charge level is further below the cut-off threshold (e.g., remaining charge <5%), the central control chip 91 completely stops the heating output, while the RGB three-color LED indicator 11 continues to flash red to remind the user to charge, thereby effectively avoiding the risk of over-discharge of the lithium battery.

[0089] The execution order of the above steps is not strictly chronological. Step S4, temperature acquisition and PWM adjustment, runs throughout the entire heating process; step S5, timing, and step S6, sleep / wake-up, operate in tandem during heating; and step S7, power monitoring, is performed throughout the entire process. Each step is centrally controlled and scheduled by the central control chip 91, forming a complete human-machine interactive control loop of "perception → recognition → decision → execution → feedback."

[0090] In one preferred parameter configuration, the preset sleep time is 10 minutes and the preset wake-up temperature difference is 2°C. In another parameter configuration, the preset sleep time can be set to 5 minutes, 15 minutes, or 30 minutes, and the preset wake-up temperature difference can be set to 1°C, 3°C, or 5°C. The specific values ​​can be adjusted according to the usage scenario, ambient temperature, battery capacity, and heating power level, and do not constitute a limitation of the present invention.

[0091] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
