Detailed Implementation

[0011] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0012] The target control method, target control device, electronic device, and storage medium of the present disclosure are described below with reference to the accompanying drawings.

[0013] Figure 1 This is a schematic flowchart of a fan control method provided in one embodiment of the present disclosure.

[0014] It should be noted that the target control method of this disclosure can be applied to a target control device, which can be configured in an electronic device so that the electronic device can perform target control functions.

[0015] like Figure 1As shown, the wind turbine control method of this disclosure includes the following steps: S101, based on the state information of the target device in the target power consumption mode, determine that the target device has experienced a target event.

[0016] In some embodiments of this disclosure, the target device may be, but is not limited to, any of the following types: Smart home devices, such as refrigeration equipment with doors, like refrigerators; Equipment that requires active cooling, such as data center equipment (e.g., servers, network switches, storage arrays).

[0017] When the target device is operating in a target power consumption mode (such as standby mode, sleep mode, or low-power mode), the system continuously monitors the device's status information, including temperature changes, vibration signals, door opening / closing signals, and battery level. If the detected status information meets preset trigger conditions, a target event is determined to have occurred on the target device.

[0018] The following is an example of a target event: Refrigerator door opening event: A door opening event is generated when a refrigerator door open signal is detected, indicating that the door is open. Server CPU temperature rise anomaly event: A temperature rise anomaly event is generated when the server CPU temperature exceeds a set temperature threshold, or when the temperature rise rate within a set time exceeds a set temperature rise rate threshold. Low battery event: A low battery event is generated when the battery level is lower than a set threshold (e.g., 18%-22%).

[0019] S102, Based on the target event, determine the target state machine associated with the target event.

[0020] In some embodiments of this disclosure, if the target event is a low-battery event where the remaining battery power of the target device is less than a set battery power threshold, the initial state machine of the wind turbine is reconstructed to obtain the target state machine. The reconstruction process is as follows: dynamic state compression technology is used to disable the pulse width modulation start state (START PWM state) in the initial state machine, and a direct state transition is configured between the power-on state (POWER_ON state) and the running state (RUNNING state), thereby skipping the soft-start process and simplifying the state machine.

[0021] For example, the initial state machine includes at least the POWER_ON state, START PWM state, and RUNNING state. When the remaining battery power is detected to be below a set power threshold, the POWER_ON and START PWM states in the wind turbine's initial state machine are merged into a simplified state; that is, the process transitions directly from the POWER_ON state to the RUNNING state, without entering the START PWM state again. This reconfiguration method can effectively reduce power consumption and control latency during the wind turbine startup phase.

[0022] The POWER_ON state refers to the initial operating state of the fan control system, where the power supply is connected but the motor has not yet started. In this state, the fan control system completes hardware initialization, parameter loading, and self-testing, preparing for subsequent startup or operation.

[0023] START PWM state: This refers to the soft-start phase before operation of the wind turbine control system, which transitions from the POWER_ON state. In this state, the main control unit in the wind turbine control system outputs a PWM signal with a gradually increasing duty cycle. This signal controls the power switching devices through the drive circuit, causing the wind turbine motor to accelerate slowly in a controlled manner. This process aims to suppress starting current surges, reduce mechanical stress, and prevent bus voltage drops.

[0024] RUNNING state: refers to the normal operating stage where the fan motor has reached the target speed and is working stably.

[0025] S103, based on the target state machine, controls the fan in the target equipment.

[0026] In some embodiments of this disclosure, during the fan startup process, a target state machine obtained by reconstructing the initial state machine is used to control the fan in the target device. That is, the fan is controlled to transition directly from the POWER_ON state to the RUNNING state, skipping the START PWM state.

[0027] Therefore, the control method disclosed herein eliminates the PWM duty cycle ramp-up process during the soft-start phase, reducing power consumption and control latency during startup and improving the fan response speed. This control method is particularly suitable for low-power scenarios. For target devices powered by batteries or equipped with batteries, this control method helps reduce startup power consumption, extend battery life, and avoid energy waste caused by redundant startup processes under power-limited conditions.

[0028] In some other embodiments of this disclosure, the target device is a refrigeration device with a door, such as a refrigerator.

[0029] If the target event is a door opening event, since opening the door will cause cold air to leak out and the cooling demand will be relatively reduced, at this time, reducing the fan speed can reduce the additional cooling loss caused by forced air supply and prevent cold air from blowing directly on the user. If the target event is a vibration event where the vibration intensity of the target equipment exceeds the set vibration threshold, the fan will be stopped. This vibration event may be caused by abnormal operation of the target equipment or external interference. Shutting down the fan prevents damage from continuous vibration and ensures system safety. The fan can be restarted as needed after the vibration subsides or the fault is resolved.

[0030] In some other embodiments of this disclosure, the target device is a target device that requires active cooling, such as a server.

[0031] If the target event is an abnormal temperature rise event of the target equipment, in order to dissipate the heat generated by the target equipment in a timely manner and prevent damage due to overheating, it is necessary to quickly increase the speed of the fan in the target equipment to enhance its heat dissipation capacity and ensure that the target equipment operates within a safe temperature range. Abnormal temperature rise events include: the temperature of the target equipment exceeding a set temperature threshold, or the temperature rise rate of the target equipment exceeding a set temperature rise rate threshold.

[0032] In some embodiments of this disclosure, such as Figure 2 As shown, the wind turbine control method also includes steps S201-S203, which are used to drive and control the wind turbine according to the actual duty cycle of the pulse width modulation signal (i.e., PWM signal) received by the wind turbine.

[0033] S201, during the operation of the fan, determine the actual duty cycle of the PWM signal received by the fan.

[0034] For example, the actual duty cycle can be determined in any of the following ways: Register read method: The main control unit in the target device can directly read the currently configured duty cycle value from the PWM output register as the actual duty cycle; Sampling measurement method: The external PWM signal is sampled and measured by a timer or input capture module, and the ratio of the high-level duration to the period is calculated as the actual duty cycle.

[0035] S202, determine the target duty cycle interval where the actual duty cycle is located from multiple set duty cycle intervals.

[0036] In some embodiments of this disclosure, multiple predefined duty cycle intervals can be pre-divided.

[0037] For example, the multiple set duty cycle intervals include a first set duty cycle interval (0% ≤ duty cycle ≤ 30%) and a second set duty cycle interval (30% < duty cycle ≤ 100%).

[0038] The first set duty cycle interval corresponds to the pulse group drive mode.

[0039] In pulse group drive mode, the original PWM signal is converted into a set of short-duration, high-frequency pulse group signals. Intermittent signals are then generated based on these pulse group signals to control the power switching devices (such as MOSFETs) in the wind turbine's drive circuit to operate intermittently. For example, a pulse group generator can enable only one or more high-frequency pulse subgroups in each control cycle, causing the MOSFET to conduct only during the effective pulse group period and remain off for the rest of the time. This drive method significantly reduces the total number of switching operations of the power switching devices, effectively suppressing switching and conduction losses when the wind turbine is under low load conditions, achieving deep energy savings. The energy-saving principle is shown in Table 1.

[0040] The second setting of the duty cycle range corresponds to the continuous PWM drive mode.

[0041] In continuous PWM drive mode, the PWM signal output by the main control unit is directly transmitted to the drive circuit as the drive signal to control the MOSFET to work continuously. Since the PWM signal remains continuous and the duty cycle can be flexibly adjusted, the fan speed can be precisely adjusted to meet the requirements of dynamic response and control accuracy of the fan in medium and high load scenarios. The energy-saving principle is shown in Table 1.

[0042] Table 1

[0043] S203, drive control of the fan's drive circuit according to the target duty cycle range.

[0044] In some embodiments of this disclosure, if the driving mode determined based on the target duty cycle range is a pulse group driving mode, the PWM signal is converted into a corresponding pulse group signal and output to the fan's drive circuit. The fan's drive circuit controls the power switching device to conduct only during the effective pulse group period in each control cycle, and remains off for the rest of the time, thereby driving the fan motor in an intermittent operating mode. This method is suitable for low duty cycle conditions and effectively reduces switching losses and static power consumption.

[0045] If the driving mode determined based on the target duty cycle range is a continuous PWM driving mode, the main control unit will directly use the PWM signal as the driving signal to control the power switching devices in the driving circuit to work continuously, so that the fan motor can obtain continuous voltage / current excitation, achieve smooth and high-precision speed regulation, and is suitable for medium and high loads or scenarios with high dynamic response requirements.

[0046] Therefore, this disclosure dynamically switches between pulse group drive and continuous PWM drive modes according to the duty cycle range, reducing the number of invalid switching of power switching devices and lowering static power consumption under low duty cycle conditions, and ensuring speed control accuracy and dynamic response performance under medium and high duty cycle conditions, thereby achieving synergistic optimization of energy efficiency and reliability across the entire load range.

[0047] In some embodiments of this disclosure, such as Figure 3 As shown, the wind turbine control method further includes steps S301 and S302, which are used to implement adaptive wind turbine drive control based on battery health status.

[0048] S301, during the fan control process in the target equipment, the health of the battery is determined based on the state parameters of the battery in the target equipment; wherein, the state parameters include at least one of the following: charging and discharging current, cumulative number of charging and discharging cycles, open circuit voltage, and operating temperature.

[0049] In some embodiments of this disclosure, the target device collects these state parameters in real time and combines them with a preset health model (such as a capacity decay model or internal resistance estimation model) to calculate the current health of the battery online in real time. This health indicator can effectively characterize the degree of battery aging or its remaining power supply capacity.

[0050] It should be noted that the preset health model (such as the capacity decay model or internal resistance estimation model) is a well-known technology in this field, and its specific implementation will not be described in detail here.

[0051] S302 adjusts the fan's operating parameters based on the battery's health.

[0052] In some embodiments of this disclosure, the operating parameters of the fan include the maximum duty cycle of the PWM signal.

[0053] The target device has a pre-set health threshold (e.g., 80%), and a differentiated control strategy is executed based on the comparison between the battery health and the set health threshold, as shown in Table 2 below: If the battery health level is greater than the set health threshold, it indicates that the battery is in good condition and can provide sufficient power support for the wind turbine. At this time, the wind turbine is controlled to operate at the first maximum duty cycle (e.g., 100%) to ensure that the wind turbine can work at full power. At the same time, the operating parameters of the wind turbine are sampled at the first sampling time interval (e.g., 10ms). This can ensure real-time and accurate monitoring of the wind turbine's operating status, ensure control precision and rapid response capability, and enable the wind turbine to adjust its working status in a timely manner according to the equipment's operating conditions.

[0054] If the battery's health status is less than or equal to the set health threshold, it indicates that the battery has aged to a certain extent and has limited remaining power supply capacity. In this case, the maximum drive capacity of the fan needs to be limited, and the fan should be controlled with a second maximum duty cycle (e.g., 80%). By reducing the maximum duty cycle, the overall power consumption of the fan can be effectively reduced, extending the battery's runtime. Simultaneously, the sampling interval for the fan's operating parameters should be adjusted to a second sampling interval (e.g., 50ms). While meeting the basic functional requirements of the fan, this reduces the number of samplings, thereby reducing energy consumption. Specifically, the first maximum duty cycle is greater than the second maximum duty cycle, and the first sampling time interval is less than the second sampling time interval. Through this differentiated control strategy, when the battery is in good condition, priority is given to ensuring the performance of the wind turbine, guaranteeing efficient operation of the target equipment; when the battery is aging, priority is given to ensuring the energy efficiency and stability of the equipment, extending the service life of the target equipment.

[0055] Table 2

[0056] Therefore, through the above mechanism, the target device can adaptively adjust the drive intensity and sampling interval of the fan according to the battery health, achieving a dynamic balance between performance and battery life throughout the entire life cycle of the target device, thereby improving the overall user experience and reliability of the target device.

[0057] In summary, the wind turbine control method proposed in this disclosure determines a target event occurring in the target device based on the state information of the target device under the target power consumption mode, determines a target state machine associated with the target event based on the target event, and then controls the wind turbine in the target device according to the target state machine. This disclosure achieves adaptive control of the wind turbine by using a target state machine matched to the target event, thereby improving the response speed under the target power consumption mode.
