Description

Technical Field

[0001] This invention relates to the field of power supply equipment safety protection, and in particular to a fault-grading protection control method and system for a laptop adapter. Background Technology

[0002] As a core power supply component for laptops, the stability of the external power adapter directly determines the operational safety and lifespan of the laptop. With the increasing demand for portability in consumer electronics, adapter designs are becoming increasingly miniaturized and lightweight, leading to higher integration of internal power devices and reduced heat dissipation space. During daily use, adapters are prone to abnormal temperature increases due to prolonged high-load operation, proximity to external heat sources, and being covered by lightweight materials such as tissues or cloth. Simultaneously, aging internal circuitry and power device malfunctions can also cause temperature runaway, resulting in safety hazards such as short circuits and fires.

[0003] To avoid the above risks, existing technologies typically employ a control strategy that triggers protection based on a single temperature threshold. Specifically, a temperature sensor is installed in the adapter casing or internal power circuit to collect temperature data in real time. When the monitored temperature reaches a preset protection threshold, protective operations such as reducing battery power and cutting off power supply are directly triggered.

[0004] Regarding the aforementioned technologies, traditional adapter protection systems rely solely on a single temperature threshold to determine whether protection is triggered, making it impossible to distinguish whether the temperature anomaly is caused by an external heat source or an internal circuit fault. Summary of the Invention

[0005] To address the limitations of traditional adapter protection systems that rely solely on a single temperature threshold to determine whether protection is triggered, this invention provides a fault-level protection control method and system for laptop adapters.

[0006] In a first aspect, the present invention provides a fault-level protection and control method for a laptop adapter, employing the following technical solution: A fault-level protection control method for a laptop adapter includes: Step 1: In response to temperature detection information, acquire the adapter power supply temperature and adapter casing temperature in real time; Step 2: Determine the current rate of change of the adapter power supply temperature based on the adapter power supply temperature; Step 3: Determine the current rate of change of adapter housing temperature based on the adapter housing temperature; Step 4: Determine the current rate of change deviation based on the current adapter casing temperature change rate and the adapter power supply temperature change rate; Step 5: When the current rate of change deviation value falls within the preset abnormal rate of change deviation range, accumulate the deviation duration; Step 6: If the deviation duration falls within the preset reliable observation duration, determine the trend of the rate of change deviation value based on the rate of change deviation value; Step 7: When the trend of the rate of change deviation value is upward, output an external interference signal and do not perform the preset battery protection operation; Step 8: When the trend of the rate of change deviation value is downward, perform battery protection operation.

[0007] By adopting the above technical solution, the system can monitor the temperature changes of the adapter power supply and casing in real time. By calculating the temperature change rate deviation and its trend, it can determine whether the abnormal adapter temperature is caused by external interference or its own malfunction. When the rate deviation trend is rising, it is determined to be external interference, and the battery protection operation is not executed, avoiding false protection caused by external factors and ensuring the normal operation of the laptop. When the rate deviation trend is falling, the battery protection operation is executed, which can promptly deal with the adapter's own malfunction, reduce the possibility of safety hazards such as short circuits and casing fires, and effectively improve the safety and stability of the laptop adapter.

[0008] Optionally, it also includes a method for performing a blowing operation when external interference signals are present, the method comprising: Step 70: When the adapter casing temperature falls within the preset danger temperature range, acquire wind direction data; Step 71: Determine the direction of heat source flow based on wind direction data; Step 72: When there is a heat source flow direction, obtain the current laptop position and the current adapter position; Step 73: Determine the first direction based on the current laptop location and the current adapter location; Step 74: Determine the second direction based on the current adapter location and heat source flow direction; Step 75: Search the preset fan database based on the first direction to determine the current blower fan number; Step 76: Determine the fan blowing angle based on the second direction; Step 77: Perform a blowing operation based on the current blower fan number and fan blowing angle.

[0009] By adopting the above technical solution, when the adapter casing temperature is within the dangerous temperature range and there is a heat source flow direction, the system can accurately determine the fan number and blowing angle based on airflow data, the position of the laptop and the adapter, and perform effective airflow. This helps to dissipate heat, reduce the adapter temperature, and decrease the risk of malfunction caused by excessive adapter temperature due to external heat source interference, further ensuring the stable operation of the laptop adapter. At the same time, precise fan control avoids unnecessary energy waste and improves heat dissipation efficiency.

[0010] Optionally, it also includes a method for performing a diagonal encircling airflow operation when the current blower fan number does not exist, the method comprising: Step 750: Determine the current adapter's heat-facing area based on the second direction and the current adapter's position; Step 751: Based on the current adapter's heat-facing area and the first direction, search the fan database to determine the current cooperating fan number; Step 752: Calculate the encirclement angle based on the current cooperating fan number and the second direction; Step 753: Perform oblique encirclement blowing operation based on the current cooperating fan number and encirclement angle.

[0011] By adopting the above technical solution, when the current fan number is not available, the system can perform a diagonal surround airflow operation by determining the adapter's heat-facing area, the cooperating fan number, and the surround airflow angle. This method can dissipate heat from multiple angles, effectively reducing the adapter's temperature even when a suitable direct airflow fan is unavailable. The diagonal surround airflow creates a more concentrated heat dissipation area, enhancing the cooling effect, reducing the risk of adapter failure due to poor heat dissipation, and improving the stability and safety of the laptop adapter under complex cooling conditions. Simultaneously, by consulting the fan database and calculating the angle, the accuracy and effectiveness of the diagonal surround airflow operation are ensured.

[0012] Optionally, it also includes a method for stopping the oblique encircling air blowing operation, the method comprising: Step 754: When performing the oblique encircling air blowing operation, obtain the current temperature of the adapter's heat-facing area in real time; Step 755: Determine the temperature change trend of the current adapter's heat-facing area based on the current adapter's heat-facing area temperature; Step 756: When the temperature change trend of the current adapter's heat-facing area is decreasing and the adapter's outer casing temperature does not fall into the dangerous temperature range, determine the current cooperative fan position based on the current cooperative fan number; Step 757: Sort the current cooperating fans from the outside to the inside to form a cooperating fan sequence; Step 758: Determine the number of the currently closed fan based on the cooperative fan sequence, and control the fan corresponding to the currently closed fan number to stop the oblique encircling air blowing operation; Step 759: After stopping the oblique encirclement operation, determine and correct the current temperature change trend of the adapter's heat-facing area based on the current temperature change trend of the adapter's heat-facing area; Step 760: When the current temperature change trend of the adapter's heat-facing area is corrected to a downward trend, proceed with steps 758 to 759; Step 761: When the temperature change trend of the current adapter's heat-facing area is corrected to an upward trend, stop executing steps 758 to 759, and control the fan corresponding to the currently closed fan number to perform an oblique encircling air blowing operation.

[0013] By adopting the above technical solution, the system can dynamically adjust the oblique, encircling airflow operation based on the temperature change trend of the adapter's heat-facing area. When the temperature shows a downward trend and the casing temperature is no longer dangerous, unnecessary fans are gradually stopped, reducing energy consumption and promptly addressing unnecessary energy waste caused by the disappearance of the heat source. If the temperature rises again, operation is resumed in a timely manner, ensuring that the adapter always remains within a safe temperature range. This intelligent control strategy not only improves energy efficiency but also flexibly responds to different temperature changes, effectively ensuring the stable operation of the laptop adapter, reducing the risk of failure due to abnormal temperatures, and further enhancing the reliability and safety of the entire system.

[0014] Optionally, it also includes a method for performing a power-off operation when there is no heat source flow direction, the method comprising: Step 78: Obtain the current adapter image information; Step 79: Determine the current expected heat source based on the current adapter image information; Step 80: When a predicted heat source is present, execute the preset pop-up reminder operation and accumulate the waiting time; Step 81: After the waiting time reaches the preset non-response time, obtain and correct the current adapter image information; Step 82: Determine the corrected expected bonding heat source based on the corrected current adapter image information; Step 83: Perform a feature comparison operation based on the corrected predicted heat source and the current predicted heat source to determine the feature similarity; Step 84: When the feature similarity falls within the preset feature consistency similarity range, perform the power off operation.

[0015] By adopting the above technical solution, when there is no heat source flow direction, the system determines the expected heat source by acquiring adapter image information, issues a pop-up reminder, and accumulates the waiting time. If the waiting time reaches the inactive time limit, the system acquires image information again to determine and correct the expected heat source, and determines the similarity through feature comparison. When the feature similarity falls within the preset feature consistency similarity range, it can be determined that the user has not manually removed the adhesive, and the power is turned off. This method can further determine whether there is a continuous heat source on the adapter when heat dissipation by blowing air is not possible, ensuring the safe operation of the laptop adapter and the entire laptop.

[0016] Optionally, it also includes a method for not performing the power-off operation when the feature similarity does not fall within the feature consistency similarity range, the method comprising: Step 840: Determine the coverage area of ​​the bonding compound based on the currently expected heat source; Step 841: When there is an area covered by the adhesive, locate the preset adapter safety range; Step 842: When the coverage area of ​​the adhesive falls within the safe range of the adapter, determine that the adapter does not cover the core heat-generating area; Step 843: Obtain the temperature of the core heat-generating area not covered by the adapter; Step 844: When the temperature of the core heat-generating area not covered by the adapter falls into the dangerous temperature range, perform a power-off operation; Step 845: Perform battery protection operation when the temperature of the core heat-generating area not covered by the adapter does not fall into the dangerous temperature range.

[0017] By employing the above technical solution, and by determining the coverage area of ​​the adhesive layer and comparing it with a preset adapter safety range, it can be determined whether the adhesive layer covers the core heat-generating area of ​​the adapter. If the coverage area of ​​the adhesive layer falls within the adapter safety range, it indicates that the core heat-generating area is not covered. In this case, the temperature of the uncovered core heat-generating area is obtained. If this temperature falls within the danger temperature range, a power-off operation is performed to avoid safety hazards caused by localized high temperatures, ensuring the safety of the device and the user. If the temperature does not fall within the danger temperature range, a battery protection operation is performed, which can reduce the load on the adapter to a certain extent, reduce the possibility of failure, and also avoid unnecessary power-off operations, ensuring that the laptop continues to operate under relatively safe conditions.

[0018] Optionally, it also includes a method for performing a blowing operation when there is an area covered by the adhesive, the method comprising: Step 846: Determine the fit size information based on the current adapter image information; Step 847: Determine the expected weight of the adhesive based on the adhesive size information; Step 848: When the expected weight of the adhesive falls within the preset blown-away weight range, obtain the position of the adhesive; Step 849: Determine the bonding agent blow-off fan number and the corresponding current bonding agent blowing angle based on the bonding agent position and the current laptop position; Step 850: Perform a blowing operation based on the adhesive blower fan number and the current adhesive blowing angle.

[0019] By adopting the above technical solution When an adhesive sticker is covering the adapter, the system can estimate its weight by determining the sticker's size information. If the estimated weight is within a removable range, the system can further determine the fan number and corresponding airflow angle for removing the sticker based on its location and the laptop's position, and then perform the airflow operation. This method can attempt to automatically remove the adhesive sticker covering the adapter without affecting the normal use of the laptop, reducing the risk of poor adapter heat dissipation due to the sticker covering.

[0020] Optionally, it also includes a method for not performing a blowing operation when the expected weight of the laminate falls within the blown-out weight range, the method comprising: Step 8500: Determine the expected area where the adhesive will be blown off based on the position of the adhesive and the current blowing angle of the adhesive; Step 8501: When there is a predicted area where the adhesive is blown off, obtain the current desktop image information; Step 8502: Determine the danger zone based on the current desktop image information; Step 8503: When the area where the adhesive is expected to fall is a dangerous area, locate an open and safe area on the desktop based on the current desktop image information; Step 8504: When there is a safe, empty area on the desktop, determine the safety sticker blowing fan number and the corresponding safety sticker blowing angle based on the safe, empty area on the desktop, the sticker position, and the current laptop position; Step 8505: When there is a safety sticker blow-off fan number and a safety sticker blowing angle, perform a blowing operation based on the safety sticker blow-off fan number and the safety sticker blowing angle; Step 8506: If there is no safety sticker blower number and no safety sticker blowing angle, the blowing operation is not performed.

[0021] By adopting the above technical solution, when the expected weight of the adhesive is within the blown-off weight range, the system will first consider the potential impact of blowing the adhesive off. By determining the expected area where the adhesive will fall, and combining this with desktop image information, the system will determine whether this area is a danger zone. If it is a danger zone, the system will search for a safe, open area on the desktop and attempt to blow off the adhesive from a safe angle. If the safe adhesive removal fan number and safe blowing angle can be determined, the blowing operation will be performed to avoid blowing the adhesive into a danger zone and causing other problems; if safe blowing parameters cannot be determined, the blowing operation will not be performed to ensure the safety of the entire usage environment.

[0022] Optional, also includes: Step 8507: Obtain the image information of the laminate; Step 8508: Analyze the image information of the adhesive to output the flammable signal of the paper towel; Step 8509: When a signal indicating that the paper towel is flammable is detected, proceed from step 846 to step 850.

[0023] By adopting the above technical solution, the system can analyze the image information of the adhesive. When the adhesive is detected to be flammable material such as tissue paper, a forced air blowing operation is performed to remove the flammable adhesive as quickly as possible, reducing the risk of fire caused by the adapter overheating. This measure further enhances the system's ability to prevent potential safety hazards and ensures the safety of the laptop adapter and its surrounding environment.

[0024] Secondly, the present invention provides a fault classification protection and control system for a laptop adapter, which adopts the following technical solution: A fault classification protection control system for a laptop adapter, comprising: The acquisition module is used to acquire the adapter power supply temperature and the adapter casing temperature; The memory is used to store the program of the fault classification protection control method for a notebook adapter as described above; The processor loads and executes programs from memory.

[0025] By adopting the above technical solution, this laptop adapter fault classification protection control system can acquire the adapter power supply temperature and adapter casing temperature in real time using the acquisition module, providing a data foundation for subsequent fault diagnosis and protection operations. The memory stores detailed fault classification protection control method programs, which the processor loads and executes. This allows the system to automatically perform a series of operations such as battery protection, air blowing, and power shutdown based on the acquired temperature data and preset logic and steps. This system architecture achieves graded protection for laptop adapter faults, taking corresponding protective measures according to different fault conditions and levels of danger. This effectively improves the safety and stability of the laptop adapter, reduces the possibility of safety hazards and equipment damage caused by faults, ensures the normal operation of the laptop, and also enhances the safety and reliability of the user's laptop use. Furthermore, the modular design of this system provides good scalability and maintainability, facilitating subsequent updates and optimizations of the protection control methods to adapt to different usage scenarios and technological development needs.

[0026] In summary, the present invention has at least one of the following beneficial technical effects: By monitoring the rate of change and trend of the adapter power supply temperature and the casing temperature, it is possible to accurately determine whether the temperature anomaly is caused by external heat source interference or internal circuit failure. In the event of external interference, only a signal is output without triggering battery protection, avoiding the problems of accidental power cuts and power reduction under traditional single-threshold protection mechanisms, thus ensuring a normal user experience for the laptop. A tiered protection system was constructed, comprising directional airflow cooling, multi-fan surround cooling, intelligent blowing away of flammable materials, and emergency power cut-off. Corresponding protection strategies were matched to different fault scenarios. At the same time, a high-priority forced blowing mechanism was set up for flammable materials such as tissues, effectively avoiding safety hazards such as overheating and fire, and short circuits, and realizing a closed-loop protection process from early warning to disposal. During the protection process, the fan operation status can be dynamically adjusted according to the temperature change trend. For example, when the heat is being dissipated at an angle, the long-distance fan can be gradually turned off to reduce energy consumption. When blowing away the attached object, the risk of the landing point is predicted by image recognition, and the object is blown in a safe, open area on the desktop first to avoid impacting fragile items or falling to the ground, thus reducing secondary interference while ensuring safety. Attached Figure Description

[0027] Figure 1 This is a flowchart of a fault classification protection control method for a laptop adapter according to an embodiment of this application. Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0029] This invention discloses a fault-level protection control method for a laptop adapter. (Refer to...) Figure 1 A fault classification protection control method for a laptop adapter includes: Step 1: In response to temperature detection information, acquire the adapter power supply temperature and adapter casing temperature in real time.

[0030] Temperature detection information refers to the collection of temperature electrical signals acquired by the internal temperature sensor and the adapter casing temperature sensor of the power adapter. This serves as the initial input signal triggering the temperature monitoring process of this method. The adapter power supply temperature refers to the temperature of the core heat-generating components inside the power adapter, specifically including the real-time temperature of power devices such as SiCMOS transistors and transformers. The adapter casing temperature refers to the real-time temperature of the outer surface of the power adapter casing.

[0031] Step 2: Determine the current adapter power supply temperature change rate based on the adapter power supply temperature.

[0032] The adapter power supply temperature change rate refers to the change in adapter power supply temperature per unit time. Specifically, it is calculated by dividing the difference in adapter power supply temperature collected at two adjacent time points by the time interval between those two time points. For example, if the adapter power supply temperature collected at time point t1 is T1, and the adapter power supply temperature collected at time point t2 is T2, with a time interval Δt = t2 - t1, then the adapter power supply temperature change rate ΔT = (T2 - T1) / Δt.

[0033] Step 3: Determine the current rate of change of adapter housing temperature based on the adapter housing temperature.

[0034] The adapter casing temperature change rate refers to the amount of change in the adapter casing temperature per unit time. The calculation method for the adapter casing temperature change rate is the same as that for the adapter power supply temperature change rate, and will not be repeated here.

[0035] Step 4: Determine the current rate of change deviation based on the current adapter casing temperature change rate and the adapter power supply temperature change rate.

[0036] The current rate of change deviation value refers to the difference between the rate of change of the adapter housing temperature and the rate of change of the adapter power supply temperature, which is obtained by subtracting the rate of change of the adapter power supply temperature from the rate of change of the adapter housing temperature.

[0037] Step 5: When the current rate of change deviation value falls within the preset abnormal rate of change deviation range, accumulate the deviation duration.

[0038] The abnormal rate of change deviation range refers to a pre-calibrated range of differences used to determine if there is an anomaly in temperature change. Deviation duration refers to the cumulative time the current rate of change deviation value remains within the abnormal rate of change deviation range. When the deviation value is within the abnormal rate of change deviation range, it indicates that the adapter casing temperature change rate is significantly higher than the internal component heating rate, potentially indicating external influencing factors.

[0039] Step 6: If the deviation duration falls within the preset reliable observation duration, determine the trend of the rate of change deviation value based on the rate of change deviation value.

[0040] Reliable observation duration refers to the minimum observation time threshold preset to avoid misjudgment due to instantaneous fluctuations. The trend of the rate of change deviation value refers to the overall trend of multiple sets of rate of change deviation values ​​collected continuously within the reliable observation duration, specifically divided into two categories: upward trend and downward trend.

[0041] Step 7: When the trend of the rate of change deviation value is upward, output an external interference signal and do not perform the preset battery protection operation.

[0042] An upward trend refers to a situation where the rate of change deviation value increases successively in three or more consecutive acquisitions within a reliable observation period. External interference signals refer to the indicator signals that this method determines are caused by external heat sources (such as hot objects touching the device or hot air blowing through it) leading to an abnormal increase in the adapter casing temperature.

[0043] Battery protection operation refers to tiered protection measures for internal faults in the power adapter, specifically including: Level 1 frequency reduction protection (reducing the PFC frequency to 600kHz), Level 2 power reduction protection (reducing the output power to 70% of the rated value), and Level 3 shutdown protection (cutting off the adapter output). Battery protection operation is set according to different fault temperature ranges of the adapter power supply temperature, aiming to prevent damage to the power adapter due to internal overheating. When the rate of change deviation value shows an upward trend, it indicates that the increase in the adapter casing temperature is caused by the continuous action of an external heat source, rather than by heat generated by internal component failure. Executing battery protection operation in this case would cause unnecessary functional limitations, therefore, it is not triggered.

[0044] Step 8: When the trend of the rate of change deviation value is downward, perform battery protection operation.

[0045] When the deviation of the rate of change is trending downward, it indicates that the difference between the rate of change of the adapter casing temperature and the rate of change of the internal adapter power supply temperature is narrowing. This is likely due to faulty overheating of internal components in the adapter, and the impact of the overheating is gradually becoming more apparent. To prevent the fault from escalating and damaging the components or affecting battery safety, the corresponding battery protection operation must be performed immediately.

[0046] This also includes a method for performing a blowing operation when there are external interference signals, the method comprising: Step 70: Obtain wind direction data when the adapter casing temperature falls within the preset danger temperature range.

[0047] The danger temperature range refers to a pre-defined temperature threshold interval for the adapter casing that could lead to performance degradation or pose a safety hazard to the surrounding environment. This range is set according to the operating state; for example, it is 60°C to 85°C when the adapter is charging, and 55°C to 80°C when it is in standby mode. Airflow data refers to the direction and angle of hot airflow collected by the laptop's built-in miniature wind speed and direction sensor, used to locate the path of heat propagation from the heat source. When the adapter casing temperature falls into the danger temperature range, it indicates that the thermal impact of the external heat source on the adapter has exceeded its natural heat dissipation capacity. Without active airflow intervention, this could further lead to overheating and damage to the adapter or trigger safety risks.

[0048] Step 71: Determine the direction of heat source flow based on wind direction data.

[0049] The direction of heat flow refers to the straight-line propagation direction of the hot airflow from the center of the heat source towards the outer casing of the power adapter. Specifically, it is calibrated by establishing a three-dimensional rectangular coordinate system with the power adapter as the origin.

[0050] Step 72: When there is a heat source flow direction, obtain the current laptop location and the current adapter location.

[0051] The current adapter position refers to the spatial coordinate system established with the geometric center of the external power adapter casing as the origin of the three-dimensional rectangular coordinate system. Its axes are defined as follows: the x-axis is the left-right direction of the adapter (right is positive), the y-axis is the front-back direction of the adapter (front is positive), and the z-axis is the up-down direction of the adapter (up is positive). The three-dimensional coordinate parameters of the adapter position in this coordinate system are fixed at (0, 0, 0).

[0052] The current position of the laptop refers to the three-dimensional coordinate parameters (x, y, z) corresponding to the geometric center of the laptop body based on the same three-dimensional coordinate system mentioned above. The sign of the coordinate value directly reflects the spatial orientation of the laptop relative to the adapter (e.g., x>0 means the laptop is to the right of the adapter, y>0 means the laptop is in front of the adapter, z>0 means the laptop is above the adapter). The absolute value of the coordinate reflects the straight-line distance between the two in the corresponding direction.

[0053] Step 73: Determine the first direction based on the current laptop location and the current adapter location.

[0054] The first direction refers to the spatial orientation and distance relationship between the laptop and the adapter in a three-dimensional coordinate system with the adapter as the origin. For example, "the laptop is located 20cm to the right, 15cm in front, and 8cm above the adapter", or "the laptop is located 18cm to the left, 10cm behind, and 5cm below the adapter".

[0055] Step 74: Determine the second direction based on the current adapter location and the direction of heat source flow.

[0056] The second direction refers to the combination of the spatial orientation and incident angle of the hot air from the heat source flowing into the adapter shell in a three-dimensional rectangular coordinate system with the adapter as the origin. The spatial orientation is characterized by the x, y, and z axis components of the hot air flow direction, and the incident angle is the angle between the center line of the hot air flow and the plane of the adapter's heat-facing side shell (the incident angle is 0° when the air is incident horizontally, and the incident angle is 0° to 90° when the air is incident obliquely from above). For example, the hot air flow is incident obliquely from the upper right of the adapter (positive x direction, positive z direction) with an incident angle of 30° or the hot air flow is incident horizontally from the front of the adapter (positive y direction) with an incident angle of 0°.

[0057] Step 75: Search the preset fan database based on the first direction to determine the current blower fan number.

[0058] The fan database refers to a structured dataset pre-stored in the laptop's control system. It contains core parameters such as the three-dimensional installation position of each built-in fan, the horizontal angle range of the airflow coverage, the pitch angle range of the airflow coverage, the effective operating distance, and the fan speed setting. All these parameters are calibrated based on a three-dimensional coordinate system with the adapter as the origin. Because the adapter's power cord has an upper limit on length, the effective operating distance and fan speed setting are set according to the maximum length of the adapter's power cord. The current fan number refers to a unique identifier code matched from the fan database, indicating a fan whose airflow coverage completely covers the adapter area, and whose installation orientation matches the pitch angle range of the airflow coverage with the height in the first direction.

[0059] Step 76: Determine the fan blowing angle based on the second direction.

[0060] The fan blowing angle refers to the three-dimensional angular parameters of the fan outlet set to precisely counteract the hot airflow, specifically the horizontal deflection angle and the pitch angle. The horizontal deflection angle is the angle between the fan outlet in the xy-plane of the three-dimensional coordinate system and the horizontal direction of the hot airflow. The pitch angle is the angle between the fan outlet in the vertical plane and the heat-facing side plane of the adapter, matching the angle of the hot airflow. For example, when the hot airflow enters from the right front of the adapter at a 30° angle of incidence, the fan's horizontal deflection angle is 45° in the opposite direction, and the pitch angle is 30°.

[0061] Step 77: Perform a blowing operation based on the current blower fan number and fan blowing angle.

[0062] The blowing operation refers to controlling a single set of matching fans to output airflow in a directional manner according to the wind speed and three-dimensional blowing angle determined by the distance between the laptop and the adapter. The airflow is directly sprayed in the opposite direction of the hot air inflow, forming a one-way opposing airflow barrier. This barrier can directly block the hot airflow from contacting the adapter shell, while also carrying away some of the heat from the adapter surface.

[0063] This also includes a method for performing a diagonal encircling air blowing operation when the current blower fan number does not exist, the method comprising: Step 750: Determine the current adapter's heat-facing area based on the second direction and the current adapter's position.

[0064] The current heat-facing area of ​​the adapter refers to the core heated surface of the adapter shell facing the direction of the hot air inflow from the heat source in a three-dimensional coordinate system with the adapter as the origin, and the spatial protective zone of 10 to 15 cm around the heated surface. The extent of this area is determined by the spatial orientation and incident angle of the second direction. For example, when the hot airflow enters from the upper right at 30°, the heat-facing area is the upper right side of the adapter shell and the corresponding space around it.

[0065] Step 751: Search the fan database based on the current adapter's heat-facing area and the first direction to determine the current cooperating fan number.

[0066] The current collaborative fan number refers to the set of identification codes of multiple fan groups selected from the fan database when no single fan group can directly cover the adapter. Although the airflow coverage of these fans cannot cover the adapter individually, they can cover the outer protective zone of the adapter's heat-facing area from different spatial orientations when combined, and the installation orientation is compatible with the first direction.

[0067] Step 752: Calculate the encirclement angle based on the current cooperating fan number and the second direction.

[0068] The encirclement angle refers to the three-dimensional angle parameter set for each set of cooperating fans to make the airflow of multiple sets of cooperating fans converge at the periphery of the adapter's heat-facing area. This angle does not directly collide with the hot airflow, but points to the edge of the outer protective belt of the heat-facing area. It includes the horizontal encirclement angle (the distribution angle of each set of fans in the xy plane) and the pitch coordination angle (the tilt angle that matches the inflow angle of the hot airflow), ensuring that multiple airflows can form a ring convergence within the protective belt.

[0069] Step 753: Perform oblique encirclement blowing operation based on the current cooperating fan number and encirclement angle.

[0070] The oblique encircling air blowing operation refers to controlling multiple sets of cooperating fans to output airflow at a preset wind speed according to their respective encircling oblique blowing angles, so that multiple airflows converge within the protective belt outside the heat-facing area of ​​the adapter, forming a closed three-dimensional annular airflow barrier. This barrier does not directly confront the hot airflow, but rather blocks the hot airflow outside the protective belt through the annular flow of airflow, while simultaneously driving the hot air inside the protective belt to dissipate rapidly.

[0071] This also includes a method for stopping the oblique encircling air blowing operation, which includes: Step 754: When performing the oblique encircling air blowing operation, obtain the current temperature of the heat-facing area of ​​the adapter in real time.

[0072] The current adapter's heat-facing area temperature refers to the average temperature value of the adapter's heat-facing area, which is collected in real time by the adapter's outer casing temperature measurement module, including the surface temperature of the adapter's core heat-receiving surface.

[0073] Step 755: Determine the temperature change trend of the current adapter's heat-facing area based on the current adapter's heat-facing area temperature.

[0074] The current temperature change trend of the adapter's heat-facing area refers to the trend of temperature rise and fall calculated from the continuously collected temperature data of the heat-facing area within a preset time window. It is divided into a downward trend (the subsequent temperature is lower than the previous temperature), an upward trend (the subsequent temperature is higher than the previous temperature), and a stable trend.

[0075] Step 756: When the temperature change trend of the current adapter's heat-facing area is decreasing and the adapter's casing temperature does not fall into the dangerous temperature range, determine the current cooperative fan position based on the current cooperative fan number.

[0076] The current collaborative fan position refers to the three-dimensional installation coordinate parameters of each collaborative fan on the laptop body in a three-dimensional Cartesian coordinate system with the adapter as the origin. It includes the spatial position information of the fan air outlet and is used to determine the distance between the fan and the adapter.

[0077] If the temperature of the adapter's heat-facing area is trending downwards and the adapter's casing temperature is not falling into the danger range, it indicates that the oblique encircling airflow operation has achieved the expected cooling effect and the adapter is in a safe temperature range. To avoid the heat source disappearing and redundant participation of the cooperating fans, some cooperating fans can be gradually turned off, and the current temperature of the adapter's heat-facing area can continue to be observed.

[0078] Step 757: Sort the current cooperating fans from the outside to the inside to form a cooperating fan sequence.

[0079] The cooperative fan sequence refers to an ordered list formed by arranging the current cooperative fan numbers in order of increasing straight-line distance from the adapter, with the adapter as the origin. Fans that are farther away from the adapter contribute less to the annular airflow barrier and are given priority for shutdown.

[0080] Step 758: Determine the number of the currently closed fan based on the cooperative fan sequence, and control the fan corresponding to the currently closed fan number to stop the oblique encircling air blowing operation.

[0081] The currently closed fan number refers to the identification code of the fan group that is furthest from the adapter in the cooperative fan sequence.

[0082] Step 759: After stopping the oblique encirclement operation, determine and correct the current adapter's current heat-facing area temperature change trend based on the current adapter's current heat-facing area temperature change trend.

[0083] Correcting the current temperature trend of the adapter's heat-facing area refers to re-collecting temperature data of the heat-facing area after shutting down some fans, and calculating the new temperature trend within the same time window.

[0084] Step 760: When the current temperature change trend of the adapter's heat-facing area is corrected to a downward trend, proceed with steps 758 to 759.

[0085] If the current temperature trend of the adapter's hot-facing area is corrected to a downward trend, it means that the airflow barrier formed by the remaining cooperating fans can still maintain effective cooling, the adapter temperature continues to decrease, and the next batch of remote fans can continue to be shut down in sequence.

[0086] Step 761: When the temperature change trend of the current adapter's heat-facing area is corrected to an upward trend, stop executing steps 758 to 759, and control the fan corresponding to the currently closed fan number to perform an oblique encircling air blowing operation.

[0087] When the current temperature trend of the adapter's hot zone is corrected to an upward trend, it indicates that the protective capability of the annular airflow barrier has weakened after some fans were turned off, and the hot airflow has begun to affect the adapter again, causing the temperature to rise. At this time, it is necessary to immediately turn on the fans that were just turned off to rebuild the complete airflow barrier and prevent the adapter temperature from entering the dangerous range again.

[0088] This also includes a method for performing a power-off operation when there is no heat source flow direction, the method comprising: Step 78: Obtain the current adapter image information.

[0089] The current adapter image information refers to the set of image data of the external power adapter and its surrounding environment collected in real time through the built-in camera of the laptop or an external vision sensor; it includes the appearance outline and placement posture of the adapter, as well as the visual features such as the shape and position distribution of objects within 10cm of the adapter, which are used to identify whether there are high-temperature objects attached to the adapter.

[0090] Step 79: Determine the current expected heat source based on the current adapter image information.

[0091] Currently, the heat source in contact is defined as a high-temperature object that is in direct contact with or about to come into contact with the adapter shell, as determined from the current adapter image information by using the YOLO real-time target detection algorithm combined with the ResNet-based heat source feature transfer learning classification algorithm. If a thermal imaging sensor is equipped, the U-Net infrared thermal image semantic segmentation algorithm is used simultaneously to enhance thermal feature recognition. Common types include hand warmers, electric blankets, high-temperature radiators, and heating surfaces exposed to direct sunlight. The determination criteria are the object's morphological features, the contact area with the adapter, and the matching results of a preset heat source feature library.

[0092] Step 80: When a heat source is expected to be present, execute the preset pop-up reminder operation and accumulate the waiting time.

[0093] A pop-up notification refers to a visual prompt window that appears on the laptop's control system screen. The window contains a text reminder that the adapter is in contact with a high-temperature heat source and should be removed immediately, an image showing the adapter's current location, and a countdown timer. This is used to inform the user of a safety risk and guide manual intervention. The waiting time refers to the time from when the pop-up notification is executed until the adapter image information is collected and corrected.

[0094] Step 81: After the waiting time reaches the preset non-response time, obtain and correct the current adapter image information.

[0095] The non-response time refers to the pre-set maximum tolerable time after receiving a pop-up reminder if the user fails to remove the attached heat source. Correcting the current adapter image information refers to re-collecting image data of the adapter and its surrounding environment using the same visual acquisition device after the waiting time has ended; the acquisition range and angle are completely consistent with the current adapter image information, used for comparison to determine whether the user has removed the attached heat source.

[0096] Step 82: Determine the corrected expected heat source based on the corrected current adapter image information.

[0097] The corrected heat source refers to the high-temperature object that is still in contact with the adapter casing, as determined by the same image recognition algorithm from the corrected current adapter image information; if the user has removed the heat source, this parameter will be empty.

[0098] Step 83: Perform a feature comparison operation based on the corrected expected heat source and the current expected heat source to determine the feature similarity.

[0099] Feature similarity refers to the quantitative matching degree obtained by matching the core features (including object shape, contact position with adapter, and contact area ratio) of the corrected expected heat source with the current expected heat source.

[0100] Step 84: When the feature similarity falls within the preset feature consistency similarity range, perform the power off operation.

[0101] The feature similarity range refers to a pre-defined threshold range of feature similarity used to determine if the user has not removed the heat source. The power-off operation refers to the laptop's control system actively cutting off the power supply path between the external power adapter and the laptop motherboard, simultaneously stopping the laptop battery discharge as a safety protection measure. This operation completely prevents the adapter from overheating and being damaged due to continuous contact with a high-temperature heat source, or from causing short circuits and other safety hazards. When the feature similarity falls within the feature similarity range, it indicates that the user did not remove the heat source during the waiting period, and the heat source continues to exert a high-temperature effect on the adapter. In this case, passive cooling and active airflow cannot eliminate the risk; power disconnection is necessary for ultimate safety protection.

[0102] This also includes a method for not performing a power-off operation when the feature similarity does not fall within the feature consistency similarity range. This method includes: Step 840: Determine the coverage area of ​​the adhesive based on the current expected heat source.

[0103] The coverage area of ​​the adhesive refers to the area and location of the contact area between the adhesive and the adapter shell, as determined by image recognition algorithms, and is expressed as a percentage of the total area of ​​the adapter shell and the corresponding coordinate range.

[0104] Step 841: When there is an area covered by the adhesive, locate the preset adapter safety range.

[0105] The adapter safety range refers to the pre-defined area of ​​the adapter shell corresponding to non-core heat-generating components (such as terminals and shell supports) inside the adapter. The normal operating temperature of this area is less than 45°C, and the temperature rise rate after the adhesive is applied is generally less than 3°C / min, which will not cause the overall overheating risk of the adapter. The range is determined based on the internal component layout and thermal simulation data of the adapter.

[0106] Step 842: When the coverage area of ​​the adhesive falls within the safe range of the adapter, determine that the adapter does not cover the core heat-generating area.

[0107] The adapter not covering the core heat-generating area refers to the high-temperature area of ​​the adapter casing corresponding to the internal core heat-generating components (transformer, switching transistors, rectifier bridge). When the area covered by the adhesive falls within the adapter's safe range, it means that the adhesive only contacts the low-risk casing area of ​​the adapter and does not block the heat dissipation channels of the core heat-generating components. The adapter does not currently pose an overheating risk due to the adhesive covering, and there is no need to immediately perform the strong protection operation of shutting off the power.

[0108] Step 843: Obtain the temperature of the core heat-generating area not covered by the adapter.

[0109] The temperature of the core heat-generating area not covered by the adapter refers to the temperature value of the corresponding shell area of ​​the core heat-generating device, which is collected in real time by a miniature temperature sensor embedded in the adapter shell.

[0110] Step 844: When the temperature of the core heat-generating area not covered by the adapter falls into the dangerous temperature range, perform a power-off operation.

[0111] When the temperature of the core heat-generating area not covered by the adapter falls into the dangerous temperature range, it indicates that the core heat-generating component inside the adapter has overheated. Even if the adhesive only covers the safe area, the natural heat dissipation capacity of the core heat dissipation channel cannot control the risk. If the power is not cut off, it may cause safety hazards such as burnout of core components and short circuit. The power must be turned off immediately.

[0112] Step 845: Perform battery protection operation when the temperature of the core heat-generating area not covered by the adapter does not fall into the dangerous temperature range.

[0113] When the temperature of the core heat-generating area not covered by the adapter does not fall within the dangerous temperature range, it indicates that the thermal state of the core components inside the adapter is within a safe range, and the bonding material does not cause substantial thermal interference to the normal operation of the adapter. At this time, it is only necessary to perform battery protection operation to reduce the overall power consumption of the system without affecting the normal use of the user.

[0114] This also includes a method for performing a blowing operation when there is an area covered by an adhesive, the method comprising: Step 846: Determine the fit size information based on the current adapter image information.

[0115] The size information of the bonding material refers to the three-dimensional parameters of the bonding material's length, width, and thickness, as well as the contact area ratio between the bonding material and the adapter shell, obtained after parsing the adapter image information through image recognition algorithms.

[0116] Step 847: Determine the expected weight of the adhesive based on the adhesive size information.

[0117] The estimated weight of the adhesive is the weight of the adhesive calculated by combining the size information of the adhesive with a preset density model of common lightweight adhesives (such as tissue paper density 0.6g / cm³, thin plastic film density 0.9g / cm³) using the formula m=ρ×V (m is weight, ρ is density, and V is volume). It is used to determine whether the adhesive can be blown away by airflow.

[0118] Step 848: When the expected weight of the adhesive falls within the preset blown-away weight range, obtain the position of the adhesive.

[0119] The blowable weight range refers to the pre-defined weight range of the adhesive that the fan airflow can effectively blow away from the adapter shell. It is suitable for lightweight and flammable adhesives such as tissues, thin paper, and plastic films. Adhesives exceeding this range (such as thick cardboard and fabric) cannot be blown away by the airflow, directly triggering a pop-up warning. The adhesive position refers to the specific coordinate position of the adhesive on the adapter shell surface, determined by an image recognition algorithm from the adapter image information. This includes the center position and boundary coordinates of the adhesive, used to locate the target area for the fan airflow.

[0120] Step 849: Determine the bonding agent blow-off fan number and the current bonding agent blowing angle corresponding to the bonding agent blow-off fan number based on the bonding agent position and the current notebook position.

[0121] The current blowing angle of the adhesive refers to the precise three-dimensional angle parameter of the fan outlet pointing towards the adhesive in a three-dimensional coordinate system with the adapter as the origin. Its value is determined by the center coordinates of the adhesive on the surface of the adapter shell and the boundary coordinates of the covered area.

[0122] Step 850: Perform a blowing operation based on the adhesive blower fan number and the current adhesive blowing angle.

[0123] This also includes a method for not performing a blowing operation when the expected weight of the laminate falls within the blown-away weight range, the method comprising: Step 8500: Determine the expected area where the adhesive will be blown off based on the position of the adhesive and the current blowing angle of the adhesive.

[0124] The expected area where the adhesive is blown off refers to the spatial coordinate range in a three-dimensional coordinate system with the adapter as the origin, which is calculated by combining the size, weight, air resistance parameters of the adhesive, and the direction of airflow thrust at the current blowing angle of the adhesive. This area includes two categories: the landing point on the desktop and the ground landing area.

[0125] Step 8501: When there is a predicted area where the adhesive is blown off, obtain the current desktop image information.

[0126] Desktop image information refers to the set of visual data collected by the laptop's built-in camera, centered on the adapter, covering the desktop and its surrounding area; it includes the placement of desktop items and the position information of the desktop edges.

[0127] Step 8502: Determine the danger zone based on the current desktop image information.

[0128] Dangerous areas refer to areas where stickers are not suitable for falling or remaining, specifically areas where stickers may collide with other items on the table or fall directly to the ground after being blown by airflow.

[0129] Step 8503: When the area where the attached material is expected to fall is a dangerous area, locate an open and safe area on the desktop based on the current desktop image information.

[0130] A safe, open area on the desktop refers to a flat, unoccupied area within the coverage of the desktop image information, at least 10cm from the edge of the desktop. This area should be at least twice the size of the adhesive layer to ensure that the adhesive layer lands smoothly on the desktop after being blown, without impacting items or slipping to the ground. If the area where the adhesive layer is expected to fall is a danger zone, it means that performing the blowing operation at the current blowing angle will cause the adhesive layer to impact and damage items on the desktop, or fall directly to the ground, increasing the cleaning burden. The blowing path needs to be replanned.

[0131] Step 8504: When there is a safe, empty area on the desktop, determine the safety sticker blowing fan number and the corresponding safety sticker blowing angle based on the safe, empty area on the desktop, the sticker position, and the current laptop position.

[0132] The safety sticker blower fan number refers to a unique identifier code of a fan matched from a preset fan database, whose blowing coverage can accurately point to an open and safe area on the desktop, and whose effective wind speed is sufficient to push the sticker to that area.

[0133] The air blowing angle of the safety fit refers to the three-dimensional angular parameter of the fan outlet pointing towards the contact gap between the fit and the adapter shell in a three-dimensional coordinate system with the adapter as the origin; it includes the horizontal orientation angle and the pitch angle.

[0134] Step 8505: When there is a safety sticker blower number and a safety sticker blowing angle, perform a blowing operation based on the safety sticker blower number and the safety sticker blowing angle.

[0135] When the fan number for the safety sticker removal device and the blowing angle for the safety sticker are present, it means that the system has been matched with a suitable fan and a precise blowing angle. This allows the sticker to be smoothly blown from the adapter surface to a clear and safe area on the desktop, achieving automatic removal of the sticker without causing damage to the item or adding to the cleaning burden.

[0136] Step 8506: If there is no safety sticker blower number and no safety sticker blowing angle, the blowing operation is not performed.

[0137] If there is no fan number or blowing angle for the safety sticker, it means that there is currently no suitable fan or blowing angle to safely remove the sticker. The pop-up window mentioned above can remind the user to manually remove the sticker.

[0138] This also includes: Step 8507: Obtain the image information of the adhesive.

[0139] The image information of the adhesive refers to the set of visual data captured by high-definition close-up of the adhesive on the surface of the adapter through the built-in camera of the laptop. It includes the texture features, edge shape, light transmittance and surface wrinkles of the adhesive.

[0140] Step 8508: Analyze the image information of the adhesive to output the flammable signal of the paper towel.

[0141] The flammable tissue signal refers to a high-priority risk trigger signal that is output after determining that the attached material is a lightweight flammable material such as tissue, toilet paper, or thin paper balls based on the image information of the attached material and through a preset tissue texture feature matching algorithm (such as fibrous texture recognition and edge fragmentation feature comparison).

[0142] Step 8509: When a signal indicating that the paper towel is flammable is detected, proceed from step 846 to step 850.

[0143] When a signal indicating the presence of flammable paper towels is detected, it means that the adhesive covering the adapter surface is made of flammable paper towels. Such items are highly susceptible to ignition and fire hazards when continuously heated by the adapter's high-temperature casing. In this case, the hazard assessment step for the area where the adhesive has fallen should be skipped, and the adhesive removal operation should be prioritized to eliminate the fire risk as soon as possible. If the adhesive subsequently falls into a dangerous area, a pop-up window should be used to remind the user to clean up the fallen material.
